An element classification item name “means” is tagged to a phrase such as “numerical analysis”. The element classification item name “Conclusion” is tagged to phrases such as “I want to solve”, “I want to know”, and so on.

  The machine learning unit 122 extracts words / phrases from the learning corpus and stores them for each classification item of the corresponding element. That is, the machine learning unit 122 uses the teacher data including the learning corpus as a learning material, learns and stores words belonging to each element classification item for each element classification item with reference to the teacher data.

  Further, the machine learning unit 122 learns and stores the appearance pattern of elements in the learning corpus. For example, by learning the appearance pattern such as in what order the words belonging to which classification item appear, such as the words belonging to the element “means” appear after the target “gas-liquid interface phenomenon” Remember. For example, an appearance pattern in which words indicating “object”, “means”, and “conclusion” appear in the order of “object → means → conclusion” is learned and stored. With such an appearance pattern, even if a word that is not included in the learning corpus appears, it is possible to recognize a word indicating “object”, “means”, and “conclusion”.

  The learning target analysis data that is learned and stored by the machine learning unit 122 is model data (model data) that indicates what element classification items are to be decomposed into the elements constituting the text data indicating the learning target. Used as.

  Further, the machine learning unit 122 outputs model data to an external computer via a communication line or a storage medium, or inputs model data learned by an external computer via a communication line or a storage medium. You can also. Therefore, the model data learned in the learning support system 1 can be used in another learning support system, and conversely, the model data learned in another learning support system can be used in the learning support system 1.

  The learning target analysis unit 123 uses the model data learned by the machine learning unit 122 or the model data acquired from the outside as a reference, and uses morpheme analysis using morpheme analysis data and dependency using dependency analysis data. Analysis, conversion of synonyms into representative words using dictionary data, and free sentence information (learning target information) indicating a learning target accepted by the input information accepting unit 121 using a well-known SVM (Support Vector Machine) Is analyzed. Therefore, the learning target analysis unit 123 analyzes the learning target information input by the learner while specifying one content from a number of phrases indicating the same content by performing processing using dictionary data. Then, the learning target analysis unit 123 identifies the content of the learning target information (that is, the intention of the learner) by identifying the elements of the phrase indicating the items “object”, “means”, and “conclusion” as a result of this analysis. Can be identified.

  FIG. 7 illustrates a screen (hereinafter also referred to as “learning target input screen”) GM for inputting a free sentence indicating a learning target displayed on the display unit 13 by the control of the display control unit 12A in the terminal 10 in the learning support operation. It is a figure to do. In the learning support operation, when the learning target input screen GM is displayed on the display unit 13 and the learner appropriately operates the operation unit 14, a free sentence indicating the learning target is described in the input field B1. Then, when the execution button EX1 is pressed by the mouse pointer MP, learning target information is input to the terminal control unit 12. The learning target information input to the terminal control unit 12 is temporarily stored in the memory 12b, subsequently transmitted to the server control unit 120 via the I / Fs 11 and 150, and received by the input information receiving unit 121. . At this time, the learning target information is temporarily stored in the memory 120b.

  For example, as shown in FIG. 7, on the learning target input screen GM, a free sentence “I want to solve the phenomenon of liquid and gas by numerical analysis” indicating a learning target is input, and input information indicating the free sentence is input information reception When received by the unit 121, the learning target analysis unit 123 includes an element “Phenomenon at the gas-liquid interface” indicating the item “target”, an element “numerical analysis” indicating the item “means”, and an element indicating the item “conclusion”. Recognize "I want to solve".

  In this case, in order to convert synonyms into one representative word using dictionary data, for example, a plurality of different expressions “gas-liquid interface” having the same meaning as “I want to solve the phenomenon of liquid and gas by numerical analysis”. "I want to solve this phenomenon by numerical analysis", "I want to solve the interface between liquid and gas using partial differential equations" and "I want to numerically calculate the flow of liquid with interfaces using partial differential equations" The learning target analysis unit 123 can recognize “a phenomenon at the gas-liquid interface”, “numerical analysis”, and “I want to solve” as elements indicating the items “object”, “means”, and “conclusion”. it can.

  The information extraction unit 124, based on the analysis result of the learning target information in the learning target analysis unit 123, one or more teaching material item elements corresponding to the learning target information received by the input information receiving unit 121, and the one or more teaching material items A plurality of teaching material item elements composed of one or more teaching material item elements having a predetermined relationship with the element, and information indicating the relationship between the plurality of learning material item elements are extracted from the content data related information 112. Note that the information extraction unit 124 extracts a part of the content data related information 112, and thus the information extracted by the information extraction unit 124 is also referred to as “partially related information”. Note that the partial related information extracted by the information extraction unit 124 is temporarily stored in the memory 120b.

  The “predetermined relationship” here refers to a relationship indicating one large concept and a relationship belonging to a learning material related element indicating the one large concept, based on one or more learning material item elements corresponding to the learning target information. Show.

  For example, the learning target analysis unit 123 recognizes an element “phenomenon at the gas-liquid interface” indicating the item “object”, an element “numerical analysis” indicating the item “means”, and an element “I want to solve” indicating the item “conclusion”. In this case, the information extracting unit 124 uses the keywords “gas-liquid interface phenomenon”, “numerical analysis”, “I want to solve” as attribute values for the attributes “target”, “means”, and “conclusion” from the content data related information 112. The attached learning material item element is extracted as a learning material item element corresponding to the learning target information.

  Specifically, for example, as shown in FIG. 4, the keywords “gas-liquid interface phenomenon”, “numerical analysis”, “I want to solve” are assigned as attribute values for the attributes “object”, “means”, and “conclusion”. The learning material item element “partial differential equation” is extracted as the learning material item element corresponding to the learning target information. In this way, the learning item element “partial differential equation” is set to be extracted for the learning goal of “I want to solve the phenomenon at the gas-liquid interface by numerical analysis”. This is because the partial differential equation is used when solving with.

Then, as shown in FIG. 8, the teaching material item element “Fundamental basis of differentiation” showing a concept larger than the educational material item element “Partial differential equation” and a plurality of teaching material item elements belonging to the educational material item element “Fundamental basis of differentiation” (Here, “ordinary differential equation”..., And “partial differential equation”...) Are partially extracted from the content data related information 112. In this way, the related teaching material item elements other than the teaching material item elements directly corresponding to the learning target information are extracted, for example, in order to solve the “partial differential equation”, the “mass conservation equation” This is because knowledge of the “momentum equation” is required. Furthermore, in order to solve the “partial differential equation”, knowledge of various approximation methods is necessary, and basic knowledge of differentiation is also necessary.

  The partial related information extracted by the information extraction unit 124 is sent to the terminal control unit 12 of the terminal 10 via the I / Fs 150 and 11 and the like. At this time, the terminal control unit 12 stores some related information in the memory 12b.

  In the terminal control unit 12, the display control unit 12A realized as a function associates the teaching material item elements included in the partial related information with each other in a network based on the partial related information stored in the memory 12b. The display unit 13 controls the display unit 13 to display the information (network information). At this time, when one or more elements with detailed items are included in the partial related information, the teaching material item elements excluding the one or more detailed item elements are controlled based on the partial related information under the control of the display control unit 12A. The network information associated with the network is visually output (displayed) on the display unit 13.

  FIG. 8 is a diagram illustrating a network information list display D <b> 1 displayed on the display unit 13. The screen including the list display of network information as shown in FIG. 8 functions as a screen (hereinafter, also referred to as “teaching material item designation screen”) on which the learner can specify necessary teaching material items at his / her own will. To do.

  For example, as shown in FIG. 9, when the learner appropriately operates a mouse included in the operation unit 14, the learner himself / herself wants to learn from a plurality of learning item elements included in the list display D1. (Hereinafter also referred to as “learning target item element”) can be selected.

  Specifically, in the list display D1 shown in FIG. 8, when the learner appropriately operates the operation unit 14 and performs a predetermined mouse operation according to a desired teaching material item element, the item selection unit 12B selects one teaching material item element with the mouse pointer MP. That is, one teaching material item element belonging to one hierarchy included in a plurality of hierarchies of the content data related information 112 is selected. At this time, information (item specifying information) for specifying the teaching material item element selected from the partial related information by the item selecting unit 12B is temporarily stored in the memory 12b.

  In the list display D1, the display control unit 12A selects one teaching material item element (hereinafter also referred to as “selected teaching material item element”) selected by the item selection unit 12B based on the item specifying information, and the one selected teaching material. One or more (here, plural) belonging to a hierarchy lower than one hierarchy to which the selected teaching material item element belongs among two or more (here, plural) of the item elements and partly related information. The teaching material item element is controlled to have a different display mode that is distinguishable from the remaining learning material item elements. Here, one selected learning material item element and one or more (here, a plurality of) learning material item elements associated so as to belong to the one selected learning material item element in the partial related information are the remaining learning materials. The display mode is controlled to be different from the item element.

  FIG. 9 is a diagram illustrating a screen after the learning target item element is selected in the list display D1. FIG. 9 shows that the display of the teaching material item elements of the series selected by the learner in the list display D1 is colored in a different color (for example, colored in red) that is distinguishable from the display of the learning material item elements of the other series. A display example D11 displayed in this manner is shown.

  Here, a process of obtaining the display example D11 of FIG. 9 will be described.

  By appropriately operating the mouse included in the operation unit 14 by the learner, the learner moves the mouse pointer MP to the element “partial differential equation” in the list display D1 shown in FIG. When right-clicking, elements belonging to the element “partial differential equation” and element “partial differential equation” (element “mass conservation law” “momentum equation” “approximation method” and all elements belonging to the element ) Is colored with a predetermined color.

  Next, when the mouse pointer MP is placed on the element “approximation method” of the elements “mass conservation law”, “momentum equation”, and “approximation method” in the same hierarchy and the predetermined mouse operation is performed, the same as the element “approximation method” Coloring (coloring of a predetermined color) of other elements “mass conservation law” and “momentum equation” in the hierarchy is canceled. If there are elements belonging to the elements “mass conservation law” and “momentum equation”, the coloring of these elements is also canceled.

  Next, when the mouse pointer MP is moved to the element “mesh cutting” among the elements “tailor expansion” and “mesh cutting” in the same hierarchy, the element “mesh cutting” Coloring (coloring of a predetermined color) of the other element “Taylor development” in the same level as that of is canceled.

  Furthermore, when a predetermined mouse operation is performed by placing the mouse pointer MP on the element “implicit method” among the elements “explicit method” and “implicit method” in the same hierarchy, the other elements “ The “explicit method” coloring (coloring of a predetermined color) is canceled.

  FIG. 10 shows a state in which the learner performs a specific mouse operation (for example, left click) with the mouse pointer MP on the element “mesh cutting” to learn the learning material item “mesh cutting”. ing.

  The element “how to cut mesh” is an element with detailed items as shown in FIG. 5, and the mouse pointer MP is put on the element “how to cut mesh” to perform a specific mouse operation (for example, left click). Then, the detailed item display request unit 12C requests to display the detailed item elements belonging to the element “mesh cutting method” in the list display displayed on the display unit 13. Then, in response to the request, under the control of the display control unit 12A, based on the partial related information stored in the memory 12b, the three subdivided detailed item elements “concept” belonging to the element “mesh cutting method” "Method A" and "Method B" are displayed on the display unit 13 in the manner shown in FIG. Therefore, the learner can learn only the teaching material “concept” and can appropriately learn other “method A” and “method B”.

  In addition, although the example which displays three detailed item elements which belong to element with detailed items "how to cut a mesh" was shown in FIG. 10, it is not restricted to this. For example, when one or more arbitrary number of detailed item elements belong to one element with detailed items, one or more arbitrary numbers of details belonging to one element with detailed items respond to a learner's operation. You may make it display an item element.

  In FIG. 10, since the learner who has acquired the items “concept” and “method A” is not confident in acquiring “method B”, the mouse pointer MP is set to the item element “method B” and a specific mouse operation is performed. The state after going is shown.

  As shown in FIG. 5, the element “B method” is an element with detailed items, and the detailed item elements “teaching material” and “confirmation test” are associated with the element “B method”. Here, similarly to the display of the detailed item element related to the element “how to cut the mesh” described above, when the mouse pointer MP is set to the element “method B” and a specific mouse operation is performed, the display control unit 12A controls it. Based on the partial related information stored in the memory 12b, the two subdivided detailed item elements “teaching material” and “confirmation test” belonging to the element “B method” are displayed on the display unit 13 in a manner as shown in FIG. Is displayed.

  In response to the input operation by the learner, the learning material item specifying unit 12D of the terminal control unit 12 specifies a learning material item element (hereinafter also referred to as “execution target item element”) indicating the content data to be executed from the learning material item specification screen. To do. The information specifying the execution target item element is temporarily stored in the memory 12b, and then transmitted to the server control unit 120 via the I / Fs 11, 150 and the like, and stored in the memory 120b.

  The teaching material extraction and provision unit 125 of the server control unit 120 extracts content data corresponding to the execution target item element from the content data group 111 by referring to the information specifying the execution target item element stored in the memory 120b. The content data extracted by the teaching material extraction / providing unit 125 is temporarily stored in the memory 120b, and then transmitted to the terminal control unit 12 via the I / Fs 11, 150, and stored in the memory 12b. That is, the content data is provided to the learner's terminal 10. At this time, the screen based on the content data is displayed on the display unit 13 by the display control unit 12A of the terminal control unit 12 based on the content data corresponding to the execution target item element stored in the memory 12b. That is, the content data is visually provided to the learner.

  For example, when the learner performs a specific mouse operation with the mouse pointer MP over the element “learning material” in a state where the learning material item designation screen as shown in FIG. By extracting and executing the content data associated with the element “learning material” of the method B in the content data group 111 in 112, the “teaching material” of the method B can be learned.

  In addition, the learner uses the “confirmation test” of the B method by performing a specific mouse operation by aligning the mouse pointer MP with the element “confirmation test” before learning using the “teaching material” of the B method. You can check your level of understanding. Specifically, in the teaching material item designation screen shown in FIG. 10, by performing a specific mouse operation by putting the mouse pointer MP on the element “confirmation test”, the content data related information 112 is associated with the element “confirmation test”. The stored content data “confirmation test” can be extracted from the content data group 111 and executed.

  FIG. 11 is a diagram illustrating a screen CT (hereinafter referred to as a “confirmation test screen”) CT displayed on the display unit 13 under the control of the display control unit 12A based on the content data “confirmation test”.

  In the confirmation test screen CT shown in FIG. 11, one or more (for example, 10 questions) test questions for “Method B” are listed, and a radio button for designating an answer (“YES” or “NO”) for each test question RB is displayed to the right of each test question. In a state where the confirmation test screen CT is displayed on the display unit 13, the learner operates the mouse as appropriate to specify the radio button RB by left-clicking the mouse with the mouse pointer MP set to the desired radio button RB. You can take action on each problem. Finally, information indicating an answer to the confirmation test (hereinafter referred to as “confirmation test answer information”) is sent from the memory 12b to the I / F 11, 150, etc. by moving the mouse pointer MP to the transmission button TB and left-clicking the mouse. Can be transmitted to the server control unit 120 via the server 120 and stored in the memory 120b.

  The server control unit 120 performs scoring on the confirmation test answer information stored in the memory 120b, and sends information indicating the scoring result (hereinafter referred to as “scoring result information”) from the memory 120b via the I / Fs 11, 150, and the like. To the terminal control unit 12. In the terminal control unit 12, after the scoring result information is stored in the memory 12b, the scoring result information is visually output on the display unit 13 under the control of the display control unit 12A. The learner can confirm his / her level of understanding by viewing the scoring results. Then, if the learner thinks that his / her own understanding level is low, the “teaching material” of the B method may be learned.

  FIG. 12 shows that the learner determined that his / her level of understanding was insufficient in the “confirmation test” and performed a specific mouse operation on the teaching material item designation screen with the mouse pointer MP on the element “learning material”. Indicates the state. FIG. 12 shows the element “Method B” and elements subordinate to the element, and the other elements are not shown.

  As shown in FIG. 12, the elements “explanation”, “example 1”, “example 2”, “question 1”, and “question 2” are associated with the element “learning material” so as to be subordinate.

  At this time, when the learner appropriately operates the operation unit 14 to perform a specific mouse operation by placing the mouse pointer MP on the element “commentary”, the learning item item specifying unit 12D causes the element “commentary” to be executed as an item item to be executed. Specified as Then, content data corresponding to the element “commentary” is extracted from the content data group 111 while referring to the content data related information 112 by the operation of the teaching material extraction providing unit 125, and the element “commentary” is operated by the operation of the display control unit 12A. A screen (for example, FIG. 13) based on the content data corresponding to is displayed on the display unit 13. That is, the contents of the teaching material related to the element “commentary” are displayed. The learner can try to understand the “Method B” by reading the contents of the “commentary” teaching material.

  Then, by reading the “commentary” through the same operation, the learner designates the elements “example 1” and “example 2” in time order as execution target item elements on the teaching material item designation screen. A screen (for example, FIG. 14) showing the contents of the teaching materials of “Example 1” and “Example 2” can be displayed on the display unit 13 so as to try to understand “Method B”. In other words, after reading the contents of the “commentary” teaching material, the degree of understanding is increased by solving “example 1” and “example 2”.

  Further, thereafter, by performing the same operation, the learner designates the elements “Problem 1” and “Problem 2” as the execution target item elements in time order on the teaching material item designation screen, thereby “Problem 1” and “Problem”. By displaying a screen showing “2” on the display unit 13 and solving “Problem 1” and “Problem 2”, the degree of understanding of “Method B” can be confirmed.

  Problems such as “Problem 1” and “Problem 2” are, for example, those in which YES / NO is selectively answered (for example, FIG. 15), as in the confirmation test shown in FIG. Such a problem can be easily scored by a computer. For this question, the learner can input information indicating the answer to the question (referred to as “question answer information”) by appropriately operating the operation unit 14 as in the confirmation test. At this time, in the terminal control unit 12, after the question answer information is stored in the memory 12b, it is determined whether or not the answer indicated by the question answer information matches the correct answer included in the content data related to the question. (Hereinafter referred to as “scoring information”) is obtained. The scoring information is transferred from the terminal control unit 12 to the server control unit 120 via the I / Fs 11 and 150 from the memory 12b and stored in the memory 120b.

  The scoring information includes information for identifying the question and information indicating whether or not the answer is correct, and the scoring information management unit 126 manages the correct answer rate of each question based on a large number of scoring information. To create a list (correct answer rate list) to be stored in the storage unit 101. For example, when the administrator variously operates the operation unit 194 of the management terminal 190, the correct answer rate list stored in the storage unit 101 is transferred to the PC control unit 192 by the function of the server control unit 120, and the display control unit Under the control of 192A, the correct answer rate list is visually output on the display unit 193. At this time, the manager visually recognizes the correct answer rate list. For example, when the correct answer rate of “question 2” is low even though the correct answer rate of “question 1” is high, Recognize that teaching materials are insufficient.

  As described above, when the manager finds a problem with a low correct answer rate, for example, the manager makes a correction to appropriately add descriptions on how to solve “question 2” to “explanation”, “example 1”, and “example 2”. Thus, the content data group 111 can be evolved to be enriched.

  Specifically, in response to the operation of the operation unit 194 by the administrator, a signal and data for correcting the content data related information 112 and the content data group 111 are transmitted from the PC control unit 192. At this time, for example, by the function of the information update unit 127, content data related to a new item constituting the teaching material is added to the content data group 111, and a new item indicating a new item for the content data related information 112 is added. A new learning material item element is added, and further, new content data corresponding to the new learning material item element is associated.

  In the above, the operation related to the teaching material provision has been described from the viewpoint of the functional configuration, but the operation flow regarding the teaching material provision will be described below.

  FIG. 16 is a flowchart showing an operation flow relating to provision of teaching materials. The operation flow illustrated in FIG. 16 is realized by control in which the functions of the server control unit 120 and the terminal control unit 12 cooperate. This operation flow is started when a predetermined signal is transmitted from the terminal control unit 12 to the server control unit 120 by the learner operating the operation unit 14 of the terminal 10 in various ways.

  In step S <b> 1, it is determined whether or not learning target information has been received by the input information receiving unit 121. Here, the determination in step S1 is repeated until learning target information is received, and when learning target information is received, the process proceeds to step S2. The following steps will be described assuming that learning target information “I want to solve the phenomenon of the interface between liquid and gas by numerical analysis” is input on the learning target input screen GM as shown in FIG.

  In step S2, the learning target information received in step S1 is analyzed by the learning target analysis unit 123. For example, the contents indicated by the learning target information (that is, the intention of the learner) are identified by identifying the elements “gas interface”, “numerical analysis”, “want to solve” indicating the items “object”, “means”, “conclusion”. Is identified. At this time, information indicating the analysis result is temporarily stored in the memory 120b.

  In step S3, the information extraction unit 124 recognizes the learning material item element corresponding to the learning target information received in step S1, based on the analysis result of step S2. For example, for the attributes “object”, “means”, and “conclusion”, the learning item element “partial differential equation” with the keywords “gas-liquid interface phenomenon”, “numerical analysis”, “want to solve” as attribute values is the learning target. Recognized as a teaching material item element corresponding to information.

  In step S4, the learning material item element recognized in step S3, a plurality of learning material item elements having a predetermined relationship with the learning material item element, and the relationship between the plurality of learning material item elements are shown. The part related information is extracted from the content data related information 112. For example, a teaching material item element “partial differential equation”, a teaching material item element “basic of differentiation” showing a concept larger than the teaching material item element “partial differential equation”, and a plurality of teaching material item elements “basic of differentiation” Partially related information associated with a large number of educational material item elements including educational material item elements (here, “ordinary differential equation”..., “Partial differential equation”...) Is extracted from the content data related information 112. Is done. At this time, some related information is temporarily stored in the memory 120b.

  In step S <b> 5, the partial related information extracted in step S <b> 4 is transferred to the terminal control unit 12. At this time, some related information is temporarily stored in the memory 12b.

  In step S6, a learning material item designation screen including a list display of network information in which each learning material item element is associated in a network state is displayed by the display control unit 12A based on the partial related information received in step S5 (for example, FIG. 8) is displayed on the display unit 13.

  In step S7, in response to the operation of the operation unit 14 by the learner by the learning material item specification unit 12D, has the execution target item element been specified from the list display of the learning material item specification screen displayed on the display unit 13 in step S6? Judge whether or not. Here, the determination in step S7 is repeated until the execution target item element is specified, and when the execution target item element is specified, the process proceeds to step S8. At this time, information indicating the execution target item element is transferred from the memory 12b to the server control unit 120 via the I / Fs 11 and 150, and temporarily stored in the memory 120b.

  In step S8, the learning material extraction providing unit 125 refers to the content data related information 112, thereby extracting content data corresponding to the execution target item element specified in step S7. At this time, the extracted content data is temporarily stored in the memory 120b.

  In step S9, the content data extracted in step S8 is transferred to the terminal control unit 12. That is, content data is provided to the terminal 10 (learner). At this time, the content data is temporarily stored in the memory 12b.

  In step S10, a screen based on the content data received in step S9 is displayed on the display unit 13 by the display control unit 12A. In other words, the learning material based on the content data is provided to the learner.

  In step S11, it is determined whether the display of the screen based on the content data started in step S10 has been completed. That is, it is determined whether or not the execution of the content data has been completed. Here, the determination in step S11 is repeated until the execution of the content data is completed, and when the execution of the content data is completed, the process returns to step S6, and a teaching material item designation screen including a list display of network information is displayed on the display unit 13.

  As described above, in the learning support system 1 according to the first embodiment, the content data related information 112 in which a plurality of teaching material item elements respectively indicating a plurality of items constituting the teaching material are associated with each other is stored in the storage unit 101. Keep it. Further, content data corresponding to each learning material item element is stored in the content data group 111 stored in the storage unit 101, and the corresponding content data is associated with each learning material item element in the content data related information 112. Remember. When the learner inputs learning target information at the terminal, the learning target information includes at least one teaching material item element corresponding to the learning target information and one or more teaching material item elements having a predetermined relationship with the one or more learning material item elements. Department related information is extracted. After that, based on the extracted partial related information, a list display of network information in which each learning material item element is associated with the network is displayed on the learner's terminal. By adopting such a configuration, the learner can easily select a desired learning material while referring to the list display of the learning material items suitable for the intention of the learner. That is, a learning material suitable for the intention of the learner can be provided.

  In addition, since the content data corresponding to the learning item item element designated by the learner in the list display is visually provided to the learner, the learning material can be obtained by the learner in accordance with his / her intention.

  In addition, in the list display of network information displayed on the learner's terminal in response to the learning target information input by the learner, the detailed item elements indicating the detailed items constituting the learning material are omitted, and each learning material item element is connected to each other. The network information associated with the network is visually output. For this reason, it is possible to avoid such a problem that there are too many learning material item elements included in the list display, and it becomes difficult for the user to find a desired learning material item from the list display.

  Further, detailed item elements are also displayed in the list display in response to the learner's request. For this reason, the learner can select a desired learning material item from a plurality of items including detailed items constituting the learning material.

  In the content data related information 112, a plurality of teaching material item elements has a hierarchical structure. In the list display, when one learning material item element is selected according to the learner's operation, the one learning material item element and the learning material item element belonging to the one learning material item element are converted into the remaining learning material item elements. Are displayed in different display modes that can be distinguished from each other. For this reason, the operation | movement which narrows down and designates a desired learning material from a list display becomes easy.

  Further, in response to the operation of the administrator, new content data is added, and a new item is also added to the content data related information 112. By adopting such a configuration, the learner can easily select a desired teaching material including a new teaching material after the administrator has evolved the contents of the teaching material as necessary.

  In addition, information serving as a reference when analyzing information input by a learner including learning target information is acquired by machine learning. By adopting such a configuration, it is possible to deal with a wide variety of information input by the learner.

  Further, when analyzing information input by a learner including learning target information, one content is specified from a plurality of expressions indicating the same content. By adopting such a configuration, it is possible to deal with a wide variety of information input by the learner.

  Further, by adopting a configuration in which the content data related information 112 is described by RDF, the content data related information 112 can be described easily.

The contents of the learning support operation such as various displays such as a list display to be presented are different. However, since the outline of the system configuration and the functional configuration are the same, description thereof will be omitted, and different points will be described below.

<Storage contents of storage unit>
FIG. 17 exemplifies some information included in the content data related information 112. FIG. 17 shows teaching materials related to items to be understood when learning “CPU hardware design”.

  As shown in FIG. 17, in the content data related information 112, three teaching material item elements “layout design”, “logical design”, and “computer architecture” are associated with the teaching material item element “CPU design”. In addition, one or more teaching material item elements are sequentially associated with the three learning material item elements. Specifically, the teaching material item elements "semiconductor device" "semiconductor properties" "electronic properties" "basic physics" "logic design" "logic circuit" "electronic circuit" "electric circuit" "basic mathematics" "hardware description language" "Programming" and "Information mathematics" are related to each other as appropriate.

  Although not shown in FIG. 17, as in the first embodiment, in the content data related information 112, a plurality of keywords representative of the content of the learning material item element are used as information for searching each learning material. It is attached to the item element. Each learning item element is associated with information (hereinafter also referred to as “learning route information”) indicating a route to be learned (learned route) when learning the (hardware) design of the CPU. Here, numbers 1 to 15 are associated as learned route information. Further, as in the first embodiment, the learning material item element included in the content data related information 112 includes an element with a detailed item associated with a detailed item element indicating a detailed item constituting the learning material. .

  The contents data group 111 includes teaching material item elements “CPU design”, “layout design”, “logic design”, “computer architecture”, “semiconductor device”, “semiconductor properties”, “electronic properties”, “basic physics”, “logic design”, “ Contents data corresponding to logic circuit, electronic circuit, electrical circuit, basic mathematics, hardware description language, programming, and information mathematics are stored.

  Although not shown in FIG. 17, as in the first embodiment, in the content data related information 112, the teaching material items below the three teaching material item elements “layout design”, “logic design”, and “computer architecture” are included. The elements are associated with data (content data) indicating the substantial contents of the learning material corresponding to each learning material item element in the content data group 111.

  Hereinafter, the learning support operation in the learning support system 1A will be described. The functional configuration realized in the server control unit 120 when the basic learning support operation is executed is the same as that shown in FIG.

<Basic learning support operation>
In FIG. 18, partial related information in which a plurality of elements below the element “CPU design” are associated with learning target information input by the learner operating the terminal 10 is extracted from the content data related information 112. It is a figure which illustrates the teaching material item designation | designated screen displayed in the display part 13 in a case.

  Here, when the partial related information (FIG. 17) extracted from the content data related information 112 by the learning material extraction providing unit 125 is transferred to the terminal control unit 12, the display unit 13 controls the learning material item under the control of the display control unit 12A. A designation screen (FIG. 18) is displayed. At this time, the display control unit 12A displays, in the display unit 13, a list of network information in which the teaching material item elements included in the partially related information are associated with each other based on the partially related information as illustrated in FIG. Controlled to display.

  At this time, under the control of the display control unit 12A, as shown in FIG. 18, the teaching material item designation screen is based on the learning path information (stored contents of the storage unit 101) included in the partial related information shown in FIG. Information based on learning path information (specifically, numbers 1 to 15) is added to each learning material item element and is visually output (displayed).

  Thus, on the learning material item designation screen, information indicating the guideline (order) of the route to be learned is attached to each of the plurality of learning material item elements, such as numbers 1 to 15, so that the learner By referring to this number, the order of teaching materials to be learned can be easily grasped.

  Here, for example, if the element “information mathematics” is an element with detailed items, the learner operates the operation unit 14 variously as shown in FIG. When a specific mouse operation (for example, left click) is performed, the detailed item display request unit 12C displays the detailed item elements belonging to the element “information mathematics” in the list display displayed on the display unit 13. To request. Then, in response to the request, under the control of the display control unit 12A, the subdivided detailed item elements “set” “XX” belonging to the element “information mathematics” based on the partial related information stored in the memory 12b. "XX", "Mapping", "Algebra Fundamentals" and "Boolean Algebra" are displayed on the display unit 13 in the manner shown in FIG. Regarding the element “information mathematics”, a detailed item element (such as “set”) in the first layer is referred to as a child item element, and a detailed item element (such as “OO”) in the second layer is appropriately referred to as a grandchild item element.

  The learner visually confirms the detailed item elements enumerated as shown in FIG. 19, confirms the detailed items for “information mathematics”, and whether or not he / she understands the contents of “information mathematics”. Judgment can be made.

  If it is determined that there is a possibility that the content of the detailed item element “information mathematics” is not understood in a state where the screen as shown in FIG. 19 is displayed, the learner operates the operation unit 14 variously. Then, for example, when a specific mouse operation is performed by placing the mouse pointer MP on the element “XX”, the element “teaching material” “confirmation test” belonging to the element “XX” as in the mode shown in FIG. Is displayed. At this time, by performing the “confirmation test”, when the learner himself can confirm the degree of understanding and determine that he / she understands, the learning related to the item element can be skipped. On the other hand, when it can be determined that the user does not understand, the teaching material related to the element “XX” can be learned by designating the element “teaching material” as the execution target item element. In addition, about the designation | designated of an element, it can be set as the method similar to the said 1st Embodiment. Then, the learner can try to understand “information mathematics” by learning the teaching material “XX”.

  In addition, by specifying any element that the learner himself does not understand from the multiple detailed item elements listed as the execution target item element, by understanding the contents of the teaching material related to the execution target item element, You can also learn that suits you.

  The basic learning support operation has been described so far, but a special learning support operation will be described below.

<Special learning support action>
In the above description, the teaching material item designation screen based on the partial related information has been described. However, in the learning support system 1A according to the second embodiment, when the partial related information is extracted, the server 100 acquires the learned knowledge of the learner. A questionnaire (question) to be investigated can be displayed on the learner's terminal, and a learning material item designation screen customized according to the answer can be displayed in response to the input of the learner's answer to the question. Hereinafter, this operation is referred to as “customization operation”.

  FIG. 20 is a block diagram illustrating a functional configuration realized by the server control unit 120 when performing a customization operation. FIG. 20 shows a configuration obtained by adding a functional configuration related to the customization operation to the functional configuration shown in FIG. Here, in the content data related information 112, question data (reaching level question data) asking the learning achievement level is associated with the teaching material item element in advance as appropriate, and further, the content data group 111 is substantively reached. Explanation will be made assuming that level question data is included.

  As shown in FIG. 20, the server control unit 120 implements a learned knowledge survey unit 128 and a display customization unit 129 when performing a customization operation.

  The learned knowledge survey unit 128 provides a question to the learner about the learning achievement level, analyzes the answer information, recognizes the learning achievement level of the learner, and learns from some related information. One or more teaching material item elements corresponding to the level are recognized.

  Here, specific processing of the learned knowledge survey unit 128 will be described.

  The learned knowledge survey unit 128 displays the partial related information when the attainment level question data is associated with the teaching material item element included in the partial related information extracted from the content data related information 112 by the information extraction unit 124. Before transferring to the control unit 12, the terminal control unit 12 is provided with the achievement level question data. At this time, the achievement level question data is temporarily stored in the memory 12b, and a screen (reaching level question screen) QG based on the achievement level question data is displayed on the display unit 13 under the control of the display control unit 12A.

  FIG. 21 is a diagram showing a display example of the achievement level question screen QG. FIG. 21 shows a reaching level question screen QG for the element “CPU design”.

  As shown in FIG. 21, the attainment level question screen QG lists one or more (for example, 10 questions) about “CPU design” and answers to each question (for example, “YES” or “NO”). Is displayed on the right side of each question. In addition, as a question, the question regarding the past learning history, such as whether the unit of the electronic circuit was acquired at the university, etc. can be considered.

  In a state where the attainment level question screen QG is displayed on the display unit 13, the learner appropriately operates the mouse so that the mouse pointer MP is set to the desired radio button RB and the mouse is left-clicked to select the radio button RB. The designated operation is performed for each question, and finally the information (answer information) indicating the answer to the question is sent from the memory 12b to the I / F 11, 150, etc. by moving the mouse pointer MP to the send button TB1 and left-clicking the mouse. Can be transmitted to the server control unit 120 via At this time, the input information receiving unit 121 receives the answer information indicating the learning achievement level of the learner, and the answer information is temporarily stored in the memory 120b.

  The learned knowledge surveying unit 128 analyzes the answer information, so that it is considered that the learner has already learned among a plurality of teaching material item elements included in the partially related information regarding the “CPU design” that has already been extracted. Recognize one or more material item elements. In this recognition process, for example, data (in which “YES” or “NO”) is associated with information indicating whether each learning item item element has been learned or not learned is associated with an answer to each question regarding the learning achievement level (for example, “YES” or “NO”) (Learning criteria data) is stored in the teaching material DB 110 in advance, and the learned knowledge survey unit 128 can refer to the learned criteria data.

  The display customization unit 129 stores information on the recognition result by the learned knowledge survey unit 128 (that is, information indicating which learning item item element is learned / unlearned), which is temporarily stored in the memory 120b. Append to information. The information generated at this time is hereinafter referred to as “partially related information with recognition information”. Then, the educational material extraction providing unit 125 transmits the partial related information with recognition information to the terminal control unit 12 and temporarily stores it in the memory 12b. At this time, the display control unit 12A was recognized by the learned knowledge survey unit 128 as being learned in the list display displayed on the display unit 13 based on the partial related information with recognition information stored in the memory 12b. One or more learning material item elements (learned item elements) are controlled to be displayed in a different manner distinguishable from the remaining learning material item elements.

  As for the different modes that can be distinguished here, for example, a mode in which the learned item elements are displayed in a color different from the remaining learning material item elements may be considered. FIG. 22 is a diagram exemplifying a list display when the learned item elements are displayed in a color different from the remaining learning material item elements, and the hatched elements indicate the learned item elements. As for the different modes that can be distinguished, other modes in which different fonts are used and different emphasis levels, such as the thickness of characters, are considered. In addition, there may be a mode in which the number of the element to be skipped is not displayed, or the number after the number of the element to be skipped is prepended and the number is attached to the element.

  With such a customization operation of the teaching material item designation screen, the learner can easily recognize the learned item element.

  In addition, the content of the customization operation on the teaching material item specification screen is not limited to the above-mentioned example, and if the learner knows that there is already learned knowledge, the teaching material item specification that indicates the learning route that skips “basic mathematics” It can be a screen. For students who have studied physical properties at university, the elements "computer architecture" "electric circuit" "electronic circuit" "information mathematics" "logic circuit" "logic design" "hardware description language" "semiconductor device" "layout" It is also possible to use a teaching material item designation screen showing a learning route for learning “design”.

  In the above, the learned item element is displayed in a different display manner that can be distinguished from the remaining learning item item elements, but it is determined that the learner has forgotten the contents of the learned item element, and the learned item element is related to the learned item element. You can also learn.

  As described above, in the learning support system 1A according to the second embodiment, in the list display of the network information included in the learning material item designation screen, information indicating the learning path is visually added to each learning material item element. Is output. For this reason, the order which a learner should learn can be grasped | ascertained easily.

  Further, the learning material item elements corresponding to the learning achievement level of the learner are recognized, and are displayed in a different display manner distinguishable from the remaining learning material item elements in the list display included in the learning material item designation screen. For this reason, the learner can easily grasp the learning path according to his / her level.

<Modification>
As mentioned above, although embodiment of this invention was described, this invention is not limited to the thing of the content demonstrated above.

  ◎ For example, in the above embodiment, when a free sentence indicating a learning target is input, the phrasal indicating the items “target”, “means”, “conclusion” is recognized by using the morphological analysis of the free sentence, and the element Is extracted from the content data related information 112, but is not limited to this. For example, one or more words are obtained by performing morphological analysis on a free sentence indicating a learning target. It is also possible to extract from the content data related information 112 the learning material item elements that are recognized and to which more keywords that match the one or more words are attached.

  In addition, in the content data related information 112, a large number (eg, 100) of free sentences indicating the learning target assumed for each learning material item element (e.g., 100 pieces) is given, and a free sentence indicating the learning target. May be extracted from the contents data related information 112.

  Further, by inputting a free sentence indicating a learning target, a list display of the content data related information 112 as shown in FIG. 3 is displayed on the display unit 13 in addition to an aspect of inputting the intention of the learner, and the learner However, by appropriately operating the operation unit 14, it is possible to narrow down the teaching material item elements that match the learning target by sequentially selecting subordinate elements from elements that indicate a larger concept (for example, “mathematics”). good.

  Furthermore, the learning target information is not limited to text data, and may be various elements such as symbols, diagrams, and tables.

  In the above embodiment, the teaching material item element is composed of words, but is not limited thereto, and may be various elements such as symbols, diagrams, tables, and the like.

  In the first embodiment, as shown in FIG. 9, the display of the selected teaching material item elements in the list display D1 is colored with a different color that can be distinguished from the display of other learning material item elements. However, the present invention is not limited to this. For example, as shown in FIG. 23, only the selected teaching material item elements in the list display D1 are displayed, and other learning material item elements are displayed from the list display D1. By erasing, the teaching material item elements of the selected series may be displayed in different manners that can be distinguished from other teaching material item elements.

  In the above embodiment, the learner appropriately selects, specifies, and inputs various information by operating the mouse as appropriate. However, the present invention is not limited to this, and various types of information included in the operation unit 14 such as a keyboard can be used. Selection, designation, input, etc. of various information may be executed by the learner operating the member. In addition, selection, designation, input, and the like of various types of information may be performed by receiving a voice uttered by a learner and recognizing the voice.

  In the content data related information 112, for example, one or more arbitrary number of learning material item elements included in the content data related information 112 may be elements with detailed items.

  In the above embodiment, the designated detailed item element is designated by designating one educational material detailed item element included in the plurality of detailed item elements in response to the learner input on the educational material item designation screen. The content data corresponding to is extracted from the content data group 111 and provided to the learner. However, the present invention is not limited to this, and by specifying one learning material item element included in a plurality of learning material item elements included in the content data related information 112, the content data corresponding to the specified learning material item element is stored in the content data group. It may be extracted from 111 and provided to the learner.

  In the above embodiment, the test question given as the confirmation test is to answer YES / NO selectively, but is not limited to this, and can be scored by a computer such as a so-called hole filling problem. Any test question is acceptable.

  In the above embodiment, the problems such as “Problem 1” and “Problem 2” are problems in a form that can be scored by a computer. However, the present invention is not limited to this, and a problem that seeks an answer in a descriptive form is also conceivable. FIG. 24 is a diagram exemplifying a screen that presents a question of a descriptive expression. In such an embodiment, after the learner solves the test question, if the user clicks a predetermined answer button, an example of the answer is shown, and the learner can judge his / her own understanding level by scoring. Anyway. In addition, when the learner inputs information indicating the scoring result (scoring result information) at the terminal 10, the scoring result information is transferred to the server control unit 120 and managed by the scoring information management unit 126 of the server control unit 120. Below, you may make it produce | generate the list | wrist which matched each answer with the correct answer rate, score distribution, etc., and memorize | store it in the memory | storage part 101. FIG.

  In the first embodiment, the learner is provided with a list display composed of learning material item elements related to learning of numerical analysis logic and algorithm for a learning target to learn numerical analysis. Not limited to this.

  For example, a learner who wants to learn numerical analysis may also want to learn programming. In such a case, it is necessary to present a list display composed of educational material item elements relating to the programming language and coding rules for the learning goal for which numerical analysis is to be learned. That is, for the learning target information, it is necessary to extract a group of learning material item elements related to learning of numerical analysis logic and algorithm and a group of learning material item elements related to learning of programming knowledge.

  However, when a plurality of groups of learning material item elements (teaching material item element groups) associated with a plurality of learning material item elements are extracted in this way, a list display indicating a plurality of learning material item element groups is displayed on the display unit 13. If displayed simultaneously, the list display becomes difficult to see, and it becomes difficult for the learner to specify the execution target item element. It can be said that such a state is a state where the input learning target information alone is not sufficient and the range of the teaching material item elements to be presented cannot be narrowed down and determined.

  Therefore, when a plurality of learning material item element groups are extracted, a list display showing the plurality of learning material item element groups is once displayed on the display unit 13, and any one learning material item element group is selected. In this way, the learner may be encouraged.

  An operation for realizing such a configuration will be described below.

  The input information receiving unit 121 receives the learning target information input by the learner, and temporarily stores the learning target information in the memory 120b. Next, the learning target analysis unit 123 analyzes the learning target information, specifies the content indicated by the learning target information, obtains information (target specifying information) for specifying the learning target, and temporarily stores it in the memory 120b. . Further, the information extraction unit 124 has a predetermined relationship with one teaching material item element corresponding to the learning target information from the content data related information 112 based on the target specifying information stored in the memory 120b and the one teaching material item element. Partially relevant information indicating a plurality of teaching material item element groups each including one or more teaching material item elements having the above is extracted, temporarily stored in the memory 120b, and transferred to the terminal control unit 12. At this time, partial related information indicating a plurality of teaching material item element groups is temporarily stored in the memory 12b. Based on the information stored in the memory 12b, the display control unit 12A controls the display of a list of a plurality of teaching material item element groups and the designation of one teaching material item element group from the plurality of learning material item element groups. A teaching material item designation screen including a message to prompt the user is displayed on the display unit 13.

  FIG. 25 is a diagram exemplifying a learning material item designation screen instructing the user to select one learning material item element group from a plurality of learning material item element groups. In the teaching material item designation screen shown in FIG. 25, a list display related to group A of learning material item elements related to learning of numerical analysis logic and algorithms, a list display related to group B of learning material item elements related to learning of programming, and Is displayed. In such a state that the teaching material item designation screen is displayed, the user performs various mouse operations on the operation unit 14 so that the mouse pointer MP is operated in accordance with the display of the group A or group B, thereby performing a specific mouse operation. One group can be selected.

  In response to this selection operation, a list display relating to one group is displayed on the display unit 13 under the control of the display control unit 12A. For example, when group A is selected on the learning material item designation screen shown in FIG. 25, a learning material item designation screen including a list display as shown in FIG.

  By adopting the configuration as described above, even when a learning target that cannot narrow down the initial learning material is input, it is possible to provide a learning material that finally matches the intention of the learner.

  As described above, in addition to a mode in which any one teaching material item element group is selected from a plurality of teaching material item element groups, various modes in which the learning material item element group is narrowed down and presented to the learner are conceivable.

  For example, teaching materials including a list display as shown in FIG. 8 are attached to the content data related information 112 such that learning of numerical analysis logic and algorithm is given priority over learning of programming knowledge. An item designation screen may be displayed on the display unit 13 and a question asking whether programming learning is necessary may be presented on the teaching material item designation screen. The learner may answer the question with “YES”, “NO”, or the like to display the learning material item element group related to learning of programming on the learning material item designation screen.

  Further, for example, at the time when learning related to one learning material item element group (for example, learning material item element group related to numerical analysis logic and algorithm acquisition) is completed, another learning material item element group (for example, knowledge of programming related knowledge) A question asking whether or not to perform learning related to the learning material item element group related to acquisition may be displayed on the display unit 13. Such an operation is realized by the following processing, for example. When the learner performs various operations on the operation unit 14 and is instructed to end learning of one teaching material item element group, the display control unit 12A controls the display unit 12A based on the partial related information stored in the memory 12b. Then, a question asking whether or not to perform learning related to another learning material item element group is displayed on the display unit 13.

  FIG. 26 is a diagram illustrating a state in which a question asking whether or not to perform learning related to another learning material item element group is displayed on the display unit 13.

  When the learner operates the operation unit 14 in a state where the screen as shown in FIG. 26 is displayed, when the mouse pointer MP is set to a predetermined OK button and the OK button is pressed, the display control unit 12A. Under the control, a learning material item designation screen including a list display relating to another learning material item element group (a learning material item element group related to acquisition of programming knowledge) is displayed based on the part related information stored in the memory 12b. Displayed in the section 13.

  Further, when two or more teaching material item element groups are extracted at the time when the learning target information is input, one teaching material item element group is selected from a plurality of learning material item element groups as shown in FIG. Instead of prompting, it may be displayed that prompting the user to input more detailed learning target information on the assumption that the condition for narrowing the teaching material item element group to one is insufficient.

  In the above embodiment, the learning of the learning material item element “learning material” has been described. However, at the end of the learning of the “learning material”, the learner may be able to input questions related to the learning material.

  For example, when learning the contents of the teaching material as shown in FIG. 12, after answering question 2, a screen (question item entry screen) for entering the question items as shown in FIG. 27 is displayed. It may be displayed on the part 13. In order to realize such an operation, for example, the data for displaying the question entry screen is included in the content data of “Question 2”, and the student inputs an answer to “Question 2”. In response to the above, a mode in which the question entry screen is displayed based on the content data of “Problem 2” under the control of the display control unit 12A is conceivable.

  In the question item entry screen shown in FIG. 27, a frame WF for inputting text information indicating the question item is arranged in the approximate center, and the learner indicates the question item in the frame WF by variously operating the operation unit 14. You can fill in the text. Furthermore, when the learner performs various operations on the operation unit 14 and performs a specific mouse operation by moving the mouse pointer MP to the transmission button TB, the transmission button TB is pressed and the question items entered in the frame WF are shown. Sentence information (question information) is transmitted from the terminal control unit 12 to the server control unit 120 via the I / F 11, 150, etc. from the memory 12b. At this time, the question information is received by the input information receiving unit 121 and temporarily stored in the memory 120b. Then, by the function of the server control unit 120, the question information is transferred to the PC control unit 192, and the question information is temporarily stored in the memory 192b. As a result, under the control of the display control unit 192A, based on the question information stored in the memory 192b, the question information is visually presented on the display unit 193 in a manner as shown in FIG. FIG. 28 shows a state where question information such as “I don't know XX of example 2” is presented visually.

  The administrator can add new content data according to the question from the learner by visually recognizing the display screen as shown in FIG. In other words, the teaching materials can be evolved in a form corresponding to the learner's situation.

  For example, if there are many questions such as “I don't know example 2” for the element “learning material” shown in FIG. 5, it is considered that there is a logical leap between example 1 and example 2. Thus, the elements “example 1-2” and “example 1-3” may be added between the element “example 1” and the element “example 2”. At this time, instead of the learning material item designation screen shown in FIG. 12, a learning material item designation screen shown in FIG. 30 may be displayed on the display unit 13. In addition, when the questioner asks for the existence of another answer to the question, an example of the answer to the question may be added.

  As an operation for realizing the addition of new content data, the following operation is conceivable as described in the first embodiment. In response to an operation by the administrator, a signal and data for correcting the content data related information 112 and the content data group 111 are transmitted from the PC control unit 192. At this time, by the function of the information updating unit 127, a new learning material item element indicating a new item constituting the learning material is added to the content data related information 112, and a new corresponding to the new learning material item element is added. The content data is associated and stored in the storage unit 110.

  In the above, the question information is transmitted via the Internet. However, the present invention is not limited to this. For example, the learner can send the question by other means such as a letter. The same measures can be taken. It is also possible to send a separate question using e-mail.

  In the above description, the administrator understands the question items by visually recognizing them and determines the data to be added. However, the server control unit 120 uses a method similar to the analysis of learning target information in the learning target analysis unit 123. Then, by analyzing the question information stored in the memory 120b, the server control unit 120 may automatically recognize information that specifies the content of the question information.

  That is, the server control unit 120 has a function of specifying one content from a number of phrases indicating the same content when analyzing various input information input by the learner such as learning target information and question information. Also good. Further, for example, data corresponding to information for specifying the content of the question information is stored in the teaching material DB 110 in advance, and the content data related information 112 is asked based on the information for specifying the content obtained as the analysis result of the question information. A teaching material item element indicating the content of new content data corresponding to the information may be added.

  Further, for example, the server control unit 120 performs language analysis using the same method as the learning target information on the question information input by the learner and transmitted from the terminal control unit 12 to the server control unit 120, Recognizing information (question specifying information) for specifying the content of information, the function of the server control unit 120 adds new content data to the content data group 111 based on the question specifying information, and adds new content data. The teaching material item element to be shown may be added to the content data related information 112. In order to realize such an operation, the question specifying information assumed in the teaching material DB 110 and new content data of additional candidates may be stored.

  In the second embodiment, information related to the learning route is displayed on the teaching material item designation screen. However, the content data may be added and the learning route may evolve. Specifically, in response to the operation of the operation unit 194 by the administrator, the information updating unit 127 of the server control unit 120 adds a new teaching material item element to the content data related information 112 and a new teaching material item. New learning route information indicating a learning route and corresponding new content data may be associated with the element and additionally stored in the teaching material DB 110. By adopting such a configuration, in the list display included in the teaching material item designation screen, information indicating the learning path is also added to the teaching material item element indicating the new content data, and is output visually. The learner can easily grasp the learning order including new teaching materials.

  For example, in the information shown in FIG. 17, information indicating a learning route such as “3.5” and the like, while adding a new teaching material item element “XX” between the element “electric circuit” and the element “basic mathematics” In addition, content data corresponding to the new teaching material item element “XXX” may be added. At this time, the content data corresponding to the learning material item element “XXX” may be added to the content data group 111.

  In the above description, the case where the contents of the question are easy to understand has been described as an example. However, the present invention is not limited to this. For example, there is a possibility that a rough question that does not understand the contents of the question is input. For example, as shown in FIG. 31, it may be possible to input a question such as “I don't know” or the like so that the subject of the question is not well understood. In such a case, for example, as shown in FIG. 32, a request for re-entry of the question is requested on the question entry screen (in FIG. 32, “I ’m sorry, please fill in so that the intention of the question is clear”). It is very convenient to display the sentence).

  A configuration example for realizing this operation will be described below.

  The input information receiving unit 121 receives the question information from the terminal control unit 12 and temporarily stores it in the memory 120b. Then, the function of the server control unit 120 determines whether or not an element belonging to a predetermined item that specifies the content of the question information is included. This predetermined item includes an item “object” indicating the subject of the question, an item “conclusion” indicating the conclusion of the question, and the like. For example, when a question “I don't know example 2” is input, the question information includes the element “example 2” for the item “object” and the element “not sure” for the item “conclusion”. It is determined. On the other hand, if the question "I don't know" is entered, the element "Conclusion" contains the element "I don't know", but the question information does not contain the element "Target" Determined.

  At this time, information indicating the determination result of the server control unit 120 is transferred from the memory 120b to the terminal control unit 12 via the I / Fs 11, 150, etc., and temporarily stored in the memory 12b. If the determination result is a determination result indicating that the question information does not include all elements belonging to the predetermined item for specifying the contents, the question items displayed on the display unit 13 under the control of the display control unit 12A. The entry screen displays a message requesting the learner to re-enter the question.

  By adopting such a configuration, it is possible to easily cope with a case where the learner's intention is not understood only from the question.

  In the above embodiment, information such as keywords is added to each teaching material item element of the content data related information 112. However, the present invention is not limited to this, and the elements “target”, “means”, “conclusion” Information (for example, a list) indicating the relationship between a plurality of elements corresponding to each and the teaching material item element is stored in the teaching material DB 110 in advance, and the learning target information is analyzed while referring to the information to cope with it. You may enable it to derive a teaching material item element.

  In the second embodiment, as an example of displaying the elements in a different manner in which the elements can be distinguished in the list display, for example, an aspect in which the learned item elements are displayed in a color different from the remaining teaching material item elements, etc. However, the present invention is not limited to this. For example, a mode in which the learned item elements are not displayed is also conceivable.

  In the second embodiment, the teaching material item designation screen is customized according to the learning achievement level of the learner, but is not limited thereto. For example, if the learner's position is different, the contents and depth to be learned in the field to be learned are different. Specifically, the degree of goal to understand (depth of knowledge required) depends on whether you want knowledge as a full-fledged designer about “CPU design” or if you want general knowledge as a manager. Different. In this way, the information regarding the learning path presented on the teaching material item designation screen may be varied depending on the required knowledge depth. For example, instead of or in addition to the question regarding the learning achievement level, a question for asking a learner the target position may be performed.

  For example, on the achievement level question screen QG, a selective question for asking a learner's target position (for example, “full-scale designer”, “manager”, etc.) is added, and teaching material item elements corresponding to the position are added. If the data to be shown is stored in the teaching material DB 110 in advance, a customized teaching material item designation screen can be presented according to the answer to the question of the target position. Specifically, taking the teaching material item designation screen shown in FIG. 22 as an example, if the target position is a full-fledged designer except for customization according to the achievement level, all teaching material item elements Is a learning target, and a careful learning path is recommended. On the other hand, if the target position is a manager, only those extracted from child item elements of “computer architecture”, “logic circuit”, “logic design”, and “hardware description language” will be subject to learning, and will be outlined in a short time. A learning route that allows you to learn

  In addition, as a method to distinguish between the case where the target position is a full-fledged designer and the case of a manager, for example, the conclusion extracted from learning target information is "I want to manage" "I want to design" "I want to make" For example, a method of separating the positions can be considered by paying attention to the fact that the position differs depending on the target position.

  In the second embodiment, the learner is asked about the learning achievement level at the time when some relevant information is extracted. However, the present invention is not limited to this, and the learning material item element is designated on the learning material item designation screen. You can start learning from an item that you do not understand by asking the learning achievement level for the specified learning item item element each time, and if it is already learned, it is recommended to skip the learning item item element. You may make it easy.

  In addition, when it can be determined that the user has already learned just by looking at the scoring result of the confirmation test or viewing the display of the small items and grandchild items, the learner operates the operation unit 14 in various ways, If it is input that is a learned item, a different display mode may be used in which the learning item item element indicating the learned item is distinguished from the learning item item element indicating the unlearned item on the learning item item designation screen.

  In the above embodiment, the learner specifies a learning material item element in accordance with his / her intention by viewing a list of network information composed of a plurality of learning material item elements and viewing learning route information. I was able to learn. However, if it is determined from the answer of the question or the like that the learner has insufficient understanding of the learning material previously learned, a warning may be given to return to the previously learned learning material.

  A functional configuration for realizing such an operation will be described below.

  For example, information (hereinafter referred to as “learning guideline information”) that associates the learning item item element to be learned next with the answer result (correct answer / incorrect answer) for the question is stored in advance in the learning material DB 110. This learning guideline information is associated with the detailed item element (hereinafter referred to as “question item element”) indicating the corresponding question item in the content data related information 112, and the question item element is included in some related information. If this is the case, a part of the related information is stored in the memory 12b in a state in which the learning guideline information is included.

  In such a state, under the control of the teaching material item specifying unit 12D, the question item element (for example, “B method”) for one teaching material item element being displayed in a list according to the operation of the operation unit 14 by the learner (for example, “Method B”) When the question 1 shown in FIG. 15 or the like is specified, the display control unit 12A controls the question to the learner (for example, question 1 shown in FIG. 15) based on the content data of the question item elements. A screen to be presented is displayed on the display unit 13.

  When the learner operates the operation unit 14 in a state where the screen is displayed, information (answer information) indicating an answer to the question is stored in the memory 12b. Furthermore, as shown in FIG. 33, the display controller 12A refers to the answer information stored in the memory 12b and the learning guideline information included in the partially related information, so that the learner should learn next. The teaching material item element (for example, the previously learned element “differential equation”) is controlled to be displayed on the display unit 13. In other words, the following learning guidelines are presented.

  In this way, according to the learner's answer to the question about one learning material item, adopting a configuration in which the learning material item element to be learned next by the learner is adopted, so that it corresponds to the situation of the learner. Since the learning guidelines are shown, the learning effect can be improved.

  In this way, if you do not understand the problem in the middle, for example if you make a mistake, you can go back to the items necessary for understanding them, but you can also automatically insert material item elements that were not originally included in the learning path. In other words, the learning path may be changed. If not further understood, a mode may be adopted in which child items and learning materials that are not normally presented are learned, and the difficulty level of the learning materials is gradually increased to match the level of the learner.

  In the above embodiment, only one type of content data is prepared for one teaching material item element. However, a plurality of types of content data corresponding to a plurality of levels are provided for one teaching material item element. You may make it prepare and provide the content data according to a learner's level.

  A functional configuration for realizing such an operation will be described below.

  The content data related information 112 includes a teaching material item element group composed of one or more teaching material item elements respectively corresponding to a plurality of levels, and the teaching material item elements associated with each other so that the teaching material item element groups of the plurality of levels belong to each other. (Hereinafter also referred to as “teaching item elements with multiple levels”). Further, information (hereinafter referred to as “level grasping question”) indicating information (hereinafter also referred to as “level grasping question”) in the content data group 111 as content data of the teaching material item elements with multiple levels is known. And information indicating the relationship between the answer result for the level grasping question and a plurality of levels (hereinafter also referred to as “answer analysis information”). Further, content data including level grasping question information and answer analysis information is associated with the teaching material item elements with multiple levels of the content data related information 112.

  In this state, the teaching material with a plurality of levels is added to the partial related information that is extracted by the information extraction unit 124 and then transferred from the memory 120b to the terminal control unit 12 via the I / Fs 11 and 150 and temporarily stored in the memory 12b. When the item element is included, the terminal control unit 12 is associated with the multi-level teaching material item element stored in the memory 12b according to the designation of the multi-level teaching material item element by the operation of the operation unit 14 of the learner. The level grasping question information is read from the content data group 111 to the memory 12b. Then, the display control unit 12A controls to display the level grasping question on the display unit 13 based on the level grasping question information stored in the memory 12b.

  When the learner appropriately operates the operation unit 14 in a state where the level grasping question is displayed on the display unit 13, information (answer information) indicating the learner's answer result to the level grasping question is received by the terminal control unit 12. And stored in the memory 12b. Next, the terminal control unit 12 reads the response analysis information associated with the teaching material item elements with multiple levels stored in the memory 12b from the content data group 111 to the memory 12b. Furthermore, the display control unit 12A refers to the response analysis information stored in the memory 12b, thereby grasping one level corresponding to the response information stored in the memory 12b. Control is performed to selectively display the grasped one-level learning material item element group on the display unit 13 from the learning material item element group.

  For example, as shown in FIG. 34, a plurality of levels of teaching material item element groups such as “Introduction”, “Intermediate”, “Advanced”, etc. are prepared for the teaching materials of the B method. Then, when the element “learning material” is designated on the learning material item designation screen, a question screen for asking the learner about the learning material item element “learning material” as shown in FIG. 21 under the control of the display control unit 12A. It is displayed on the display unit 13. Next, information (answer information) indicating the learner's answer to the question of the learning material item element “learning material” is stored in the memory 12b by the same operation as the operation on the question screen shown in FIG. Furthermore, the display control unit 12A selects one level of teaching material item elements corresponding to the answer information from among a plurality of levels of teaching material item element groups ("Introduction", "Intermediate", and "Advanced" teaching material item elements shown in FIG. 34). Control is performed so that the group is selectively displayed on the display unit 13. FIG. 35 shows a state in which the teaching material item element group related to “Introduction” is selectively displayed.

  In this way, according to the learner's answer to the question about one learning material item, adopting a configuration in which the learning material item element to be learned next by the learner is adopted, so that it corresponds to the situation of the learner. Since the learning guidelines are shown, the learning effect can be improved.

  In the above embodiment, the learning materials in the engineering field such as “the phenomenon at the gas-liquid interface” and “CPU circuit” have been described as examples. However, the present invention is not limited to this. For example, various learning materials in the humanities and medical fields The present invention can also be applied to educational materials.

  One example will be briefly described below.

  For example, a student studying nursing learns “basic nursing” and then “nursing by disease”. After that, "practical training" is performed to acquire practical knowledge. By associating each teaching material item element of the learning system in the nursing field according to the system, and further associating the details of each teaching material item element in the same format as shown in the first embodiment, A learning support system similar to that shown in the embodiment can be constructed.

  On the other hand, if such a detailed learning support system that systematically associates teaching material item elements related to nursing knowledge can be constructed, it can be useful for general patients and families.

  For example, it is common for patients who have had their stomach removed due to stomach cancer to struggle to eat after discharge. However, in hospitals, it is not possible to give dietary guidance to patients who visit the clinic after discharge. At that time, the patient and family can access the learning support system to refer to the diet control method and the defecation control method after the stomach is excised. In addition, information that is not in the teaching materials is fed back to the administrator by asking questions, and the administrator answers the questions by himself / herself, and at the same time incorporating the answer into the appropriate position of the teaching material item elements, The learning path to be presented can also be evolved. In addition, if this mechanism is used, various experiences of general patients can be collected and teaching materials based on the experiences of patients can be easily created.

  In the above-described embodiment, the server 100, the management terminal 190, and the terminals 10 to 50 are configured separately, and various types of data are transmitted and received via the network line NT. 100, the management terminal 190, and the functions of the terminals 10 to 50 may be mounted on one computer (for example, a personal computer).

  ◎ In addition, as shown in FIG. 24, questions that ask the learner for answers in a narrative form are presented, and the learner judges the degree of understanding by looking at the answer examples after solving the test questions. However, the teaching material item element to be learned next may be automatically and visually output on the display unit 13 by using the self-understanding degree.

  Hereinafter, a specific example will be described. In the learning target input screen GM shown in FIG. 7, learning target information “I want to solve the phenomenon of the interface between the liquid and the gas with an electric field applied by numerical analysis” is input, and the network information shown in FIG. The case where the teaching material item designation screen including the list display D1 is presented on the display unit 13 will be described as an example.

  Here, in the content data related information 112, for example, as shown in FIG. 36, the detailed item element “teaching material” and “confirmation test” are subordinate to the element “momentum equation” with detailed items. The detailed item elements “explanation”, “example 1”, “example 2”, “question 1”, “question 2”, and “example of answer” are subordinate to the element “learning material” with detailed items. Further, content data is associated with the detailed item elements “explanation”, “example 1”, “example 2”, “question 1”, “question 2”, and “example of answer”.

  In FIG. 37, in the learning material item designation screen including the list display D1 (FIG. 8), the learner tries to learn the learning material item “momentum equation” and the mouse pointer MP is put on the element “momentum equation” and is included in the operation unit 14. A state in which a specific mouse operation (for example, left click) is performed is shown. When the mouse pointer MP is placed on the element “momentum equation” and a specific mouse operation (left click) is performed, the detail item display requesting unit 12C includes details belonging to the element “momentum equation” with detailed items in the displayed list display. Requests that an item element be displayed. Then, in response to the request, under the control of the display control unit 12A, based on the partial related information stored in the memory 12b, the two subdivided detailed item elements “belonging to the momentum equation” “ “Learning Material” and “Confirmation Test” are displayed on the display unit 13 in the manner shown in FIG.

  FIG. 38 shows a state where the learner has performed a specific mouse operation on the teaching material item designation screen by placing the mouse pointer MP on the element “teaching material” with detailed items. FIG. 38 shows the learning material item element “momentum equation” and the learning material item element subordinate to the learning material item element, and the other learning material item elements are not shown.

  As shown in FIG. 38, the detailed item elements “explanation”, “example 1”, “example 2”, “question 1”, “question 2”, and “example of answer” are associated with the educational material item element “learning material”. It has been.

  At this time, when the learner appropriately operates the operation unit 14 to perform a specific mouse operation by putting the mouse pointer MP on each learning item item element, each learning item item element is executed by the learning item item specifying unit 12D. Specified as For example, after the learner learns “commentary”, “example 1”, and “example 2”, the learning material item elements “question 1” and “question 2” are sequentially specified as execution target item elements on the learning material item designation screen. By displaying the screens indicating “Problem 1” and “Problem 2” on the display unit 13 and solving “Problem 1” and “Problem 2”, the degree of understanding of the “momentum equation” can be confirmed. .

  FIG. 39 is a diagram exemplifying a screen (problem presentation screen) for presenting the content of the question (question) of the descriptive expression related to the learning material item element (question item element) “question 2”.

  In the problem presentation screen shown in FIG. 39, the problem sentence “Show basic equations that are established instantaneously for a conductive fluid with a free surface that has been processed with an incompressible Newtonian fluid” is placed at the top of the screen. From the center to the bottom of the screen, there is a field (answer field) WA that allows you to input text related to the answer, and a command button (answer example request button) RX for requesting display of an example of the answer is placed at the bottom right of the screen ing. When the learner operates the operation unit 14 to enter an answer to the question sentence WD in the answer column WA and then presses the answer example request button RX with the mouse pointer MP, the learning material item designation unit 12D currently displays the answer. The learning material item element “answer example” corresponding to the learning material item element “question 2” related to the question presentation screen is automatically specified as the execution target item element.

  FIG. 40 and FIG. 41 are diagrams illustrating a screen (hereinafter, also referred to as “answer example presentation screen”) that presents an answer example corresponding to the question (question) of the descriptive expression related to the teaching material item element “answer example”.

  In the answer example presentation screens shown in FIGS. 40 and 41, the upper half is configured by an area RA1 in which the answer examples are presented (hereinafter also referred to as “answer example presentation area”) RA1, and the lower half indicates the level of understanding of the learner about the problem. An area for inputting (hereinafter also referred to as “understanding level input area”) RA2 is configured. In the initial state, an answer example presentation area RA1 is mainly displayed as shown in FIG. 40, and thereafter, the scroll bar SB at the right end of the screen is slid by the mouse pointer MP, so that the degree of understanding is shown as shown in FIG. The state where the input area RA2 is mainly displayed and the state where the answer example presenting area RA1 is mainly displayed as shown in FIG. 40 can be appropriately switched.

  As shown in FIG. 40, in the answer example presentation area RA1, the problem sentence “Show a basic equation that is established instantaneously locally for a conductive fluid with a free surface that has been processed with an incompressible Newtonian fluid.” WD Is arranged, and a column (answer example column) WX in which answer examples corresponding to the questions are displayed from the center to the lower part of the screen is arranged. In the answer example column WX, for example, an answer example (exemplary answer) as shown in FIG. 42 is visually presented. By visually recognizing the answer example, the learner can understand the degree of understanding of his / her problem and can deepen the understanding.

  However, for questions that ask complex expressions, it is difficult to let the computer determine the correctness or wrongness of the answer, or the part that cannot be understood, and it is more efficient for the learner to judge by referring to the answer example. It can be said. In view of this, in the understanding level input area RA2, the learner inputs the understanding level as a result of referring to the answer example, so that the learning material provided thereafter is optimized.

  As shown in FIG. 41, in the comprehension input area RA2, question sentences for asking the comprehension level of the learner's problem are listed, and radio buttons for selectively answering with YES or NO to the right of each question sentence, respectively. RB1 is provided. Here are four questions: "Are you able to show the mass conservation equation?" "Are you able to show the equation of motion?" "Are you able to express the term of electrostatic force?" Each question sentence asks whether the content is already understood by the user or not yet understood. Here, when the user operates the operation unit 14 variously, the mouse pointer MP is appropriately placed on the radio button RB1 and left-clicked, so that a black circle indicating that the radio button RB1 is appropriately designated appears. be able to.

  Further, at the bottom of the understanding level input area RA2, a command button (hereinafter also referred to as “next button”) NX requesting to proceed to the next learning after selecting an answer is arranged, and a mouse pointer is appropriately selected. When the next button NX is pressed by MP, information indicating the degree of understanding regarding the user problem input in the understanding level input area RA2 is transferred from the terminal control unit 12 to the server control unit 120. The information indicating the degree of understanding (hereinafter also referred to as “understanding level information”) includes information for specifying the content that the user has already understood regarding the question (hereinafter also referred to as “underlying content information”) and the user regarding the question yet. Information for identifying content that cannot be understood (hereinafter also referred to as “ununderstood content information”).

  Since this understanding level information includes ununderstood content information, it can be regarded as information (learning target information) related to a goal that the user should learn (that is, want to learn). Here, the learning target analysis unit 123 analyzes the learning target information and recognizes the ununderstood content information. For example, in the comprehension level input area RA2 shown in FIG. 41, when “NO” is specified for the question sentence “Did you show the mass conservation formula?”, The “mass conservation law” is not understood content information. Recognized as The rules for realizing this recognition may be stored in the storage unit 101 as appropriate. The rule may be, for example, information that associates the content of the question text, the answer “NO”, and the ununderstood content (for example, the law of conservation of mass).

  Here, in the learning material DB 110 in the storage unit 101, each ununderstood content information included in a plurality of ununderstood content information is included in the content data related information 112 and configured by one or more teaching material item elements. It is assumed that information (hereinafter also referred to as “information element association information”) in which information (partially related information) associated with each other is stored in advance. In this information element association information, partial related information including the learning material item element related to the learning material item to be learned is associated with the ununderstood content information.

  Under such conditions, when the next button NX of the understanding level input area RA2 is pressed with the mouse pointer MP, the learning target analysis unit 123 recognizes the ununderstood content information and the information extraction unit 124 recognizes the ununderstood content information. Is associated with the information element association information. Then, the partial related information is transferred to the terminal control unit 12, and the display control unit 12A displays a list of information (network information) in which the teaching material item elements included in the partial related information are associated with each other in a network form. Displayed visually on the display unit 13.

  FIG. 43 and FIG. 44 are diagrams exemplifying screens (that is, teaching material item designation screens) on which some related information corresponding to ununderstood content information is visually presented. The teaching material item designation screen shown in FIG. 43 is displayed when the answer “NO” is designated to the question sentence “Have you shown the mass conservation formula?” In the understanding level input area RA2 shown in FIG. If the answer “NO” was specified for the sentence “Have you shown the equation of motion?”, And the answer “NO” was specified for the question sentence “Have you expressed the term of surface tension?” It shows a teaching material item designation screen that is displayed when the menu item is displayed. Here, if the mass conservation equation or the equation of motion itself cannot be shown, it is determined that the learner does not have an understanding of the differential method but has insufficient knowledge of fluid mechanics. Network information related to the learning system is shown. Further, even when the surface tension term cannot be expressed, it is determined that knowledge of fluid dynamics is insufficient, and thus network information related to the fluid dynamics learning system is shown.

  Also, the teaching material item designation screen shown in FIG. 44 is displayed when the answer “NO” is designated to the question sentence “Did you express the term of electrostatic force?” In the understanding level input area RA2 shown in FIG. The teaching material item designation screen to be displayed is shown. Here, when the term of the electrostatic force cannot be expressed, it is determined that the knowledge of electromagnetism is insufficient, and thus network information related to the electromagnetism learning system is shown.

  The learner can deepen the understanding of the contents that are not yet understood by performing learning or the like while appropriately specifying the learning material item elements on the learning material item designation screen as shown in FIGS. 43 and 44.

  FIG. 45 is a flowchart showing an operation flow according to this modification. This operation flow is started when a teaching material item element (for example, the element “question 2”) related to the problem of the descriptive expression is designated as the execution target item element, and the process proceeds to step SP1.

  In step SP1, the display unit 13 displays a question presentation screen on which a question (question) of a narrative expression is presented under the control of the display control unit 12A. For example, when the learner appropriately operates the operation unit 14 to perform a specific mouse operation with the mouse pointer MP on the learning item item element “Problem 2” on the learning item item designation screen, the learning item item designation unit 12D The teaching material item element “Problem 2” is designated as the execution target item element, and the designation information is transferred to the server control unit 120. At this time, the teaching material extraction providing unit 125 extracts the content data corresponding to the execution target item element “Problem 2” from the content data group 111 and transfers the content data to the terminal control unit 12. Then, the display control unit 12A of the terminal control unit 12 displays a problem presentation screen as shown in FIG. 39 on the display unit 13 based on the content data corresponding to the execution target item element “problem 2”.

  In step SP2, the terminal control unit 12 determines whether display of an answer example is requested. For example, when the answer example request button RX is pressed with the mouse pointer MP on the question presentation screen, it is determined that display of the answer example is requested, and the process proceeds to step SP3. On the other hand, the determination in step SP2 is repeated until the answer example request button RX is pressed with the mouse pointer MP.

  In step SP3, the learning material item specifying unit 12D specifies the learning item item element “answer example” associated with the question item element related to the question currently being asked in the content data related information 112 as the execution target item element.

  In step SP4, the display control unit 12A displays an answer example presentation screen on the display unit 13 based on the content data relating to the element “answer example” specified in step SP3.

  In step SP5, the terminal control unit 12 determines whether or not the understanding level information is input on the answer example presentation screen. Here, if the next button NX provided in the understanding level input area RA2 on the answer example presentation screen is pressed with the mouse pointer MP, it proceeds to step SP6 assuming that the understanding level information has been input. Note that the determination in step SP5 is repeated until the next button NX is pressed.

  In step SP6, the terminal control unit 12 accepts understanding level information input on the answer example presentation screen. At this time, the understanding level information is transferred from the terminal control unit 12 to the server control unit 120 and received by the input information receiving unit 121.

  In step SP7, the learning target analysis unit 123 analyzes the understanding level information received and transferred in step SP6. Here, ununderstood content information included in the understanding level information is recognized.

  In step SP8, the information extraction unit 124 extracts partial related information corresponding to the analysis result in step SP7 (that is, ununderstood content information) from the content data related information 112. For example, in the information element association information stored in the teaching material DB 110, partial related information associated with ununderstood content information is extracted from the content data related information 112. Here, the partial related information is transferred from the server control unit 120 to the terminal control unit 12.

  In step SP9, based on the partial related information extracted in step SP8 under the control of the display control unit 12A, the information (network information) in which the teaching material item elements included in the partial related information are associated in a network form. The list display is visibly displayed on the display unit 13, and the operation flow ends.

  In the above configuration, after the learner answers the question, an example of the answer is presented to the learner. Then, when information related to contents that the learner who has viewed the answer example cannot understand is input, a list display of network information in which the teaching material item elements corresponding to the information are associated in a network form is presented. For this reason, the learner can easily grasp the learning material corresponding to his / her level. That is, with this configuration, it is possible to provide a learning material suitable for a learner's intention such as wanting to perform proper learning.

  In the above, an alternative answer is requested for the question asking for the degree of understanding. However, the degree of understanding is input as a free sentence (free sentence), and the learning target analysis unit 123 explained in the above embodiment. A configuration may be adopted in which the understanding level information is analyzed by the same language processing as that of the object, and the unrecognized content information is recognized by recognizing each element related to the items “target”, “conclusion”, and the like. For example, when the free sentence “Fe term, I don't know” is input as an understanding level, the element “Fe term” related to the item “target” and the element “I don't know” related to the item “Conclusion” are recognized. A configuration in which information indicating content that is not understood by the learner (ununderstood content information) is recognized.

  In the case of adopting such a configuration, the information extraction unit 124 analyzes the understanding level information in the same manner as the process of extracting some related information based on the learning target information analysis result in the above embodiment. A plurality of teaching material item elements corresponding to the ununderstood content information, and one or more teaching material item elements having a predetermined relationship with the one or more learning material item elements. Information indicating the relationship between the plurality of teaching material item elements and the plurality of teaching material item elements may be extracted from the content data related information 112 as partially related information.

  Further, the analysis result (that is, the recognized ununderstood content information) by the learning target analysis unit 123 is transferred to the management terminal 190, and the ununderstood content information is output visually under the control of the display control unit 192A. May be. With this configuration, the administrator can determine that it is necessary to review the contents of the teaching material at a place where the learner does not frequently understand (or mistake) after learning the teaching material. Therefore, it is preferable because the administrator can change the contents of the teaching materials as appropriate.

  For example, in the PC control unit 192, ununderstood content information of a large number of learners is statistically processed, and the information is table-like information that summarizes the number of inputs according to information indicating content that the learner cannot understand. If the list display of the information is visually output to the display unit 193 under the control of the display control unit 192A, the administrator can easily grasp the location where the learner frequently trips (cannot understand). preferable. Then, when the administrator operates the operation unit 194 of the PC control unit 192 in various ways to input various information, the contents of the teaching material DB 101 are appropriately changed by the function of the information update unit 127.

  Regarding the content change of the teaching material DB 110 by the function of the information updating unit 127, for example, the following modes 1 to 4 may be considered.

<Aspect 1>
Based on information input from the management terminal 190 by the administrator of the system, which is a specific user, the information update unit 127 makes a new data different from the plurality of content data already included in the content data group 111 in the storage unit 101 Content data related information 112 is added to the content data related information 112, and a new teaching material item element corresponding to the new content data is different from the plurality of teaching material item elements already included in the content data related information 112. Added. At this time, in the content data related information 112, the function of the information updating unit 127 associates a new teaching material item element with an existing teaching material item element as appropriate, and new content data is associated with the new teaching material item element. Associated. Examples of addition of such new teaching material contents include addition of “examples” aimed at improving the multistage and steady understanding as shown in FIG.

<Aspect 2>
Based on information input from the management terminal 190 by the administrator of the system that is a specific user, the information update unit 127 performs at least one of the plurality of content data already included in the content data group 111 in the storage unit 101. One or more contents data is changed. An example of such a change in the content data is a change in the content data related to the enhancement of the content related to the element “commentary” aimed at eliminating the adverse effects due to lack of explanation.

<Aspect 3>
Based on the information input from the management terminal 190 by the administrator of the system, which is a specific user, the information update unit 127 uses the existing information regarding the association between the plurality of teaching material item elements that define the learning path in the content data related information 112. A new association different from the association is added. As an example of adding such a new association, for example, when it is considered that it is better to learn the understanding of another equation in order to understand a certain equation, a new association for adding the learning route is added. Addition etc. are mentioned.

<Aspect 4>
Based on the information input from the management terminal 190 by the administrator of the system that is a specific user, the information update unit 127 changes the association between the plurality of teaching material item elements that define the learning path in the content data related information 112. The Examples of such a change in association include, for example, a change in association between a plurality of teaching material item elements for changing the learning path when the order in which learning materials are to be learned is incorrect.

  As for modes 3 and 4, when learning route information (for example, numbers 1, 2, 3,...) As shown in the second embodiment is associated with each learning material item element. Further, addition and change of learned route information can be considered.

  In this way, a specific user such as an administrator can add a new teaching material item element or content data, update content data, or between multiple teaching material item elements in consideration of the learner's understanding. Can be added, or the association between a plurality of teaching material item elements can be updated. As a result, the teaching materials are optimized.

  Here, the content data group 111 and the content data related information 112 are appropriately updated by the information update unit 127 based on information input from the management terminal 190 by the administrator. However, the present invention is not limited to this, and IP address filtering, Information input for information update may be permitted to the terminal by inputting a password or ID. In such a configuration, the content data group 111 and the content data related information 112 are operated by a user (a specific user such as an administrator) variously operating a predetermined device (terminal or the like) to which access right for information update is given. Will be updated accordingly.

  In this specification, adding new content data to the content data group 111 means adding separate content data different from the content data already included in the content data group 111. In addition, adding a new teaching material item element to the content data related information 112 adds a separate teaching material item element different from the teaching material item elements already associated with each other in the content data related information 112, It is to associate with the teaching material item element of. And the new item which comprises a learning material is a separate item different from the item which has already comprised the learning material.

  The present invention can also be used for learning in various other fields such as troubleshooting. As an example of trouble handling learning, there is learning about trouble handling of a copying machine. For example, if a “toner fixing failure” occurs in a copying machine, “the pressure applied to the toner during fixing, the heating temperature of the toner is low”, “the melting point of the used toner is high”, “the used toner This may be caused by a large particle size.

  Assuming that the learning material item for learning about trouble handling in such a case is included in the trouble shooting learning material of the copying machine, for example, in the content data related information 112, an element with detailed items “toner fixing failure” The detailed item elements “pressure and temperature of toner”, “melting point of toner”, and “particle size of toner” are related to each other, and when the learning target information “There is poor fixing” is input by the service person, the content data Partial related information including an element with detailed items “toner fixing failure” and detailed item elements subordinate to the element may be extracted from the related information 112 and displayed visually. With such a configuration, the service person can appropriately learn about troubleshooting for “fixing failure”. This learning can be used for training and training of service personnel, and is also useful from the viewpoint of obtaining practical reference information for dealing with actual troubles.
