Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a computer-aided education support system capable of improving the efficiency of education by individually grasping the progress of learners by using a computer and instructing each of them. about the arm.

[0002]

2. Description of the Related Art A conventional computer-based education support system (C
AI: Computer Aided Instruction System) is roughly classified into three types according to the form of the system. They are (a) center method, (b) network method and
(c) It is a stand-alone method. (a) In the center method, various teaching materials and user information such as learning history and grades are stored in the memory of the host computer, and each user can use a terminal, personal computer, workstation, etc. connected to this computer. Learn by using. (b) The network system uses a computer network. There may be a central host computer in the computer network, but it may not exist. Even if they exist, unlike the center system, the data such as the teaching materials are not centrally arranged in the host computer, but the learning materials are managed by each individual computer connected to the network. The host computer is only used, for example, for user management, learning history management, teaching material upgrade, and the like. Further, in the (c) stand-alone method, all the processes such as management of the learning material and management of the learning history of the user are processed by only one computer. Regarding the system form of these computer use education support systems, for example, "CA
I Handbook "(supervised by Watanabe and Sakamoto, Fuji Techno System, 1989), pp.446-460, and for frame type systems, the same as pp.212-223.

[0003]

Whatever the above-mentioned method (a), (b) or (c) is used, the central educational method for these systems is the so-called "frame type method". It is a technique. This frame-type technique uses a sequence of electronic images such as picture-story show paper, which is a teaching material called a frame, and sequentially presents them to the user. In the process of sequentially presenting frames, exercises and the like are inserted, the progress is checked, and next, teaching materials that match the progress are presented. In this method, it is necessary to incorporate the teaching material and its related information for responding to various changes in the user's progress status, and the order of the progress, etc. in the program as static logic in advance. However, it is difficult to incorporate information that can handle all situations. In a normal educational environment that does not use a computer, a teacher can dynamically select teaching materials according to the learning situation of the user. Also, the user can obtain information other than the predetermined information from the teacher. However, in an educational environment that uses a computer, the user cannot freely select a teaching material or refer to information other than what the system has depending on the learning situation. That is, the user has no choice but to see the teaching material in some predetermined order.

In a normal educational environment that does not use a computer, the teacher can give appropriate education while the teacher and the student look at a certain teaching material together. However, such an ordinary learning environment also has the above-mentioned (a), (b) or (c).
This method cannot be realized. The reason is that the same screen is physically shared by different computers, teachers and students cannot see the same screen, and even if one screen is operated, the other screen is affected. This is because it cannot be exerted. The present invention has been made in view of the above circumstances, and an object of the present invention is to solve the above-mentioned problems in the conventional technology and easily present necessary information to a user in accordance with his / her learning situation. and to provide a computer usage Education <br/> system possible. Another object of the present invention is to
Even if the teacher and the student who are the users are physically far away,
Can be made to dress affect each other the screen and the operation against it, the teacher makes a fine guidance to the students, to be subjected Hisage the computer usage education support system, such as can be finely grasp the progress of students is there.

[0005]

The above objects of the present invention are as follows.
(1) Divide the teaching material into appropriate sizes according to the educational content,
Separated teaching materials each having a learning material identifier attached thereto, link information indicating a relation between the separated learning materials as a pair of the learning material identifiers, and a partially separated learning material identification for identifying a part of the learning material
A storage device storing a child, and (2) a display device that switches and displays the breakable teaching material and the link information including the contents of the breakable teaching material and the learning material identifier attached to the break teaching material, (3 ) One of the selections corresponding to the display of the break-out teaching material on the display device and one selection of the link information corresponding to the display of the contents of the break-out teaching material and the link information on the display device are input. An input device, and (4) in response to the selection of the delimiter teaching material from the input device, the content of the delimited teaching material selected and link information including the teaching material identifier of the delimiting teaching material are read from the storage device, and the display device (5) The teaching material identifier is included in the selected link information according to the selection of the link information from the input device,
A second means for reading the content of the other separated teaching material not displayed on the display device and the other link information including the teaching material identifier of the other separated teaching material from the storage device and outputting the read content to the display device. It is achieved me by the computer usage education support system which is characterized in that it has.

[0006]

In the computer-aided education support system according to the present invention, the teaching material is divided into certain units, the links showing the relationship between the divided teaching materials are defined, and the link information is always displayed on the screen. This allows you to specify the link information and freely walk between the teaching materials. That is, by following the link information,
You can easily refer to the necessary information. Also, it is possible to define links for some of the teaching materials,
Make it easier to obtain a more detailed explanation of a part of the teaching material and a little special information. Further, by using a computer network to operate a plurality of computers in an interlocking manner and transferring information on the operation for one computer to another computer, one educational environment can be realized on the plurality of computers. For example, by using the system according to the present invention, students and teachers can carry out highly-dense education with each other and improve their effects.

This is a partial display area for displaying link information for displaying the link information defined in the separated teaching material. Figure 8
6 is a flowchart of processing executed by the central processing unit 201 in the present embodiment. First, an initial screen shown in FIG. 6 is displayed in order to select a teaching material for the user. Specifically, the content of the delimiter teaching material file 205 is read out to the main storage device 208, and the delimiter teaching material identifier 301 therein.
Is displayed according to the format shown in FIG. 6 (step
801). Next, the user receives a selection input of the teaching material from the input device 202 or the pointing device 203.

In the case of using the input device 202, the number designated as the break teaching material is input, and the pointing device 20
In the case of 3, the name of the separated teaching material is recognized from the clicked position (step 802). In order to allow the user to confirm the selected content of the teaching material, the identifier of the selected delimited teaching material is displayed in the teaching material selection unit 602 on the initial screen. The subsequent steps are repeated until the user finishes using the selected teaching material. The substance of the separated teaching material is read into the main storage device 208 corresponding to the selected separated teaching material. In detail, the contents of the area (file) indicated by the pointer 304 to the entity of the selected delimiter teaching material are stored in the main storage device 2
It is read into 08 (step 803). Link information file 2
The link information indicating the delimited teaching material for which the link source delimited teaching material identifier 402 is selected is read from 06 and stored in the main storage device 208 (step 804). Further, the partial break teaching material showing the break teaching material for which the break teaching material identifier 502 is selected is read from the partial break teaching material file 207 and stored in the main storage device 208 (step 805). Next, the information read in steps 803 to 805 is displayed on the screen of the display device 204 according to the format shown in FIG.

First, the data read in steps 803 and 805 is displayed in the teaching material display partial display area 702, and the link information read in step 804 is displayed in the link information display partial display area 703. Next, in the command display partial area 701, the command for the separated teaching material is displayed. Examples of commands are'Delete ',' Edit ',
There are commands such as "Add" and "End" (Step 80
6). Next, a command input by the input device 202 or the pointing device 203 is accepted (step 807). Start the processing program corresponding to the entered command and process the command (step 80).
8). Steps 807 and 808 are repeated until a command indicating the end is input for the break teaching material. Above,
The process for one piece of teaching material is completed. Next, the display process of step 806 will be described in detail with reference to FIG. The display device 204 supports a multi-window system capable of displaying a plurality of windows on the same screen. Here, a partial display area 70 on the screen shown in FIG.
One window is assigned to each of 1, 702 and 703, and these three windows are managed (displayed and processed) as one group.

First, three windows are created, and these three windows are created.
Group one window so that it can be operated as one window (step 901). Well-known X-
When using a window system, a window containing three windows is created. This is temporarily called a root window. Next, as sub windows of this root window, windows corresponding to the partial display areas 701 to 703 shown in FIG. 7 are generated. A plurality of windows generated as subwindows can be operated as if they were one window. A unique identifier is given to each subwindow. here,
The identifiers of the sub-windows corresponding to the partial display areas 701 to 703 are set to s-w-1, s-w-2 and s, respectively.
-W-3. The identifier of the root window for collectively handling these three is s-0.
Next, the data of the separated teaching material read in step 803 is displayed in the sub window sw-2 (step 90).
2). The link information read in step 804 is displayed on the sub window sw-3 (step 903).

Next, the partial break teaching material data read in step 803 is displayed in the sub window sw-2.
(Step 904). For this purpose, first, the size of the display area of the partial break teaching material is calculated using the information on the position where the partial break teaching material should be displayed. For example, in the case of text data, the size of the display area is calculated from the number of vertical and horizontal dots for displaying the start / end line / digit and one line and one digit. In the case of an image or a figure, the size of the display area can be calculated in the same way from the coordinate data of the upper left and the lower right. A window having the same size as the display area thus obtained is generated as a subwindow of the subwindow sw-2. That is, the subwindow s-
Using w-2 as a root window, a sub-window is further created for each of the partially-separated teaching material display areas. After that, the data of the partial break teaching material is displayed in the sub window. This process is repeated for the number of the partial break teaching materials read in step 805. In this way, the display of the partial break teaching material is completed. Finally, the subwindow s-
An icon or the like indicating a command is displayed on w-1 (step 905). The above is the display processing in step 806 (display of teaching material data).

Next, step 807 and step 808 in FIG.
The command reception and execution process of is described in detail with reference to the process flowcharts shown in FIGS. When the screen of the display device 204 is clicked by the pointing device 203, information as to which window is clicked and which window is clicked are obtained. The information is represented by a set of the window identifier and the clicked coordinate (step 1001).
Next, three processes are performed according to the type determined from the window identifier, that is, the type of the clicked window.
It branches to (1, 2, 3) (step 1002). If the command display partial display area 701 is clicked, the process branches to 1 and the command designated is obtained from the clicked coordinates (step 1003). The processing program corresponding to the specified command is activated, and the process returns to the command reception step (step 807) (step 1004).

If the teaching material display partial area 702 is clicked, the process branches to 2, and it is determined whether or not the obtained coordinates indicate a partial break teaching material display subwindow. Specifically, it is determined whether or not it is included in the sub-window for displaying the partial break teaching material calculated in step 904 (step 1005). If the partial break teaching material display window is not shown, for example, a bell is rung as an error (step 1009). If the partial break teaching material display window is shown, the link information display partial display area 703 is cleared (step 1006). In step 805, the link name 506 of the link information of the partial break teaching material read in the main storage device 208 is set to the partial display area 703 for link information display.
(Step 1007). Furthermore, for later processing,
The partial break teaching material clicked flag indicating that the partial break teaching material is picked is turned on. Although not shown, the partial break teaching material clicked flag is provided in the work area in the main storage device 208 (step 1008).

When the link information display partial display area 703 is clicked, the process branches to 3 and which link information is specified is obtained from the obtained coordinates (step 1010).
The window displaying the break teaching material is deleted (step 1011). If the partial break teaching material clicked flag is ON in step 1008, steps 803 to 806 are repeated, and the break specified in the break teaching material name 507 specified in the link information of the partial break teaching material read in step 805. Open the teaching material and step to accept commands
Return to (step 807) (step 1012). In addition, when the partial break teaching material clicked flag is OFF, step
803 to 806 are repeated to open the separated teaching material specified in the link destination 507 specified in the link information read in step 804, and the process returns to the command reception step (step 807) (step 1013). This is the end of the command processing. In the present embodiment, the X-window system is assumed for ease of explanation, but since similar functions are supported in other multi-window systems, the above contents can be applied without depending on the window system. .

Next, a modification of the processing shown in FIG. 13 will be described with reference to FIG. Use the multi-process function (multi-tasking function) supported by many computers. The difference between the processing of FIG. 14 and the processing of FIG. 13 is that the step corresponding to step 1011 is eliminated and the display window of the currently displayed breakable teaching material is not closed. Instead, a process (task) for displaying a new breakout material in a new window using the multi-process function.
Is generated in the process of step 1012 of FIG.
Perform steps 1111 and 1112 corresponding to 1013. That is, a program having the same function is generated as another process, and the processes shown in FIGS. 9, 11, 12 and 14 are started for the designated break teaching material. As a result, the newly generated process can realize a function of newly generating one root window, displaying the designated teaching material in the root window, and not closing the teaching material that has been displayed until then. Inputs are allowed for the individual root windows thus created, so that all root windows have exactly the same function. When using this function, a command to close the break teaching material is prepared as a command shown in the command display part area.

Next, an example different from the above of the teaching material selection processing of step 802 of FIG. 8 will be described using the flowchart shown in FIG. Information for search is input (step 1201), then search is executed based on the search information (step 1202), and the result of the search is displayed (step 1203).
A specific process in these steps is to display a delimiter material based on a keyword input by attaching a keyword to the delimiter material. Further, when the input is not a keyword but a natural language sentence including the keyword, the keyword is extracted from the character string. The details will be described below. FIG. 16 is a flowchart showing the natural language analysis process of step 1201 of FIG. First, morphological analysis is performed to determine conjugations by determining conjugations of input words, processing suffixes, prefixes, etc.
(Step 1301). Next, the syntactic analysis for analyzing the syntactic structure of the input sentence is performed (step 1302), and the analysis result obtained by the steps up to that point is output (step 1303).

FIG. 17 is a diagram showing an example of the structure of dictionary data used in the natural language analysis process shown in FIG. 1 in the figure
Reference numeral 401 is a heading section that defines forms of inflectional words, prefixes, synonyms, and the like, and 1402 eliminates the polysemy of words in each heading section, and a regular word section that represents a representative word.
Reference numeral 1403 denotes a meaning / part-of-speech code portion for entering a previously defined part-of-speech or a symbol representing the meaning in order to express the meaning of each regular word. In the above-mentioned meaning / part-of-speech code portion 1403, a certain specific code, for example, a code “kw” meaning “may be a keyword” is given to a word that can be a keyword for a search in advance.
In addition, a meaning code is given to a word that cannot be a keyword such as a particle, auxiliary verb, or conjunction, if necessary. Here, a code "n-kw" which means "not to be a keyword" is given. The dictionary data shown in FIG. 17 can be stored in, for example, the main storage device 208 in FIG.

FIG. 18 is a diagram of a table data structure representing the syntactic analysis result of the input natural language sentence output in step 1303 of FIG. Here, 1501 is a clause number part indicating the number of the clauses divided as a result of the input sentence analysis, 1
Reference numeral 502 denotes a clause portion indicating a clause, 1503 denotes a clause portion 1502.
Numeral 1504 is a regular word part indicating a regular word, and a reference numeral 1504 is a meaning code portion indicating a part of speech / semantic code of the regular word of the regular word part 1503. The analysis result content shown in FIG. 18 is stored in the main storage device 208. Hereinafter, referring to FIGS.
Detailed operation will be described. When the processing shown in FIG. 15 is started, a search request is input by inputting a character string (step 120).
1). If the search request is entered in keyword format,
The process moves to the search execution process (step 1202). When the search request is input as the search sentence in the natural language, the search sentence in the natural language input is analyzed according to the process of FIG.

First, the morphemes of the input sentence are analyzed (step 1
301), split the input sentence into phrases. Next, the following processing is repeated for each of the divided clauses. The phrase to be processed is compared with each of the headwords 1401 in FIG. 17, and if there is a matching headword, the corresponding regular word 1402 and meaning / part of speech code 1
403 is stored in the columns of the regular word 1503 and the meaning / part of speech code 1504 of the corresponding node number 1501 (the sequence number from the beginning of each divided clause) in the analysis result table of FIG. After the processing is completed for each clause, FIG.
Check the meaning and part-of-speech codes in the analysis result table shown in, collect the words that can be keywords, that is, the regular words 1503 when the meaning code is'kw ', and use this as a keyword to indicate the target break material for the user. Be a set of. For example, when there are m keywords, the set of these keywords is expressed as kw-1 to kw-m. If the user directly specifies the keyword instead of entering the natural language, in step 1201 of FIG. 15, the direct kw-
1 to kw-m will be obtained. When the set of keywords is obtained, a search is then performed (step 1202) to search for the necessary delimited teaching material. The procedure of this search is shown in FIG.
Follow the flowchart shown in.

FIG. 19 is a flow chart showing a search procedure when there are p pieces of delimiting teaching materials (ft). In the description of FIG. 19, symbols are used as follows. kw-i is the i-th keyword. ft-j is an identifier indicating the j-th segment teaching material. The number of keywords is sequentially increased from i = 1 (steps 1601 and 1602), and the number of separated teaching materials is sequentially increased from j = 1 (steps 1603 and 1604). The following processing is repeated until the number of times is multiplied. Counter variable count
The value of r (j) is set to 0 (step 1605), and the number of keywords to be added, k = 0, is set (step 1606). Further, the following processing is repeated according to the number of assigned keywords (step 1607). The i-th keyword kw-i and the j-th separated teaching material ft-j k-th keyword 303 (see FIG. 3)
If and match, a counter variable counter (j) indicating the number of matching keywords for the j-th teaching material
Is incremented by 1 (steps 1608 and 1609). This processing is applied to all separated teaching materials by using the given keyword kw.
Repeat from -1 to kw-m. After the processing is completed for all the keywords, the teaching material with the largest number of matching keywords is selected.

After making the above selections, step 8 of FIG.
After the processing from 03, the teaching material data is displayed (step 806), and the command is accepted and executed (steps 807 and 808). It should be noted that in the process of selecting the break-out teaching material that best matches the user's request, advanced processing can be performed, for example, by adding a weight to each keyword. Even in this case, the basic processing is the same as described above. Next, a modification of the system configuration that realizes the above-described embodiment will be described in detail. 20
It is a block diagram of the modification of a computer use education support system.
Reference numerals 1701 to 1708 in FIG. 20 correspond to 201 to 208 in FIG. 2, and the external storage device 1709 stores a table for storing user management information.
Is added. FIG. 21 shows an external storage device 170.
It is a block diagram of the user management table in 9. 1801 is a field for entering the name of a user, 1802 is a field for entering a password for each user, 1803 is a field for entering the number of break-out teaching materials that the corresponding user has already learned, and 1804 is a user already learned This is a field for entering a list of the names of teaching materials.

FIG. 22 is a flowchart of the processing executed by the central processing unit 1701 in this modification. When the system is activated, first, a screen for inputting the user's identifier is displayed (step 1901). After the user inputs the identifier, the user management information is read from the user management information storage device using this user identifier (step 1902). In this case, by setting a password, it is possible to exclude unauthorized use by a user who does not have a valid use right. Next, the computer use education support system shown in FIG. 8 is started, and the processes 801 to 808 are started (step 1903). Next, the following processing is repeated until the end of the system is selected. That is, when a certain teaching material is designated (step 1904) and the teaching material is designated, the already-learned teaching material name (1804 in the table) in the user management information is searched, and if the teaching material designated in step 1904 is specified. If the teaching material is included in the already-learned teaching material name 1804, a message to that effect is output. Then, the teaching material other than the designated teaching material is presented (step 1905).

If the teaching material designated in step 1904 has not been learned, the designated break teaching material is presented (step 1906). Next, the name of the learning material designated in step 1904 is added to the learned learning material name 1804 in the user management information (step 1907). By the processing described above, it is possible to improve the efficiency of education by presenting more appropriate teaching materials according to the progress status of learning of the user. The following selections can be made as other teaching materials presented in step 1905 of FIG. That is, (a)
Present the following teaching materials. (b) Present teaching materials that include more general concepts. (c) Present an exercise related to it, and select whether to re-present the already-learned teaching material or the next teaching material depending on the answer to the exercise. In the method (a), steps
The teaching material designated as the next teaching material after the teaching material designated in 1904 is displayed on the initial screen (see FIG. 6) at system startup.

The next teaching material can be designated by using the link name 403 in FIG. 4, that is, the link expressing the related information. In the method (b), the link information 403 of FIG. 4 can be used as a teaching material including a more general concept. Further, (c) if the exercise is defined as a link in the teaching material and the exercise is not yet solved, the exercise is presented. If there are no exercises, (a) (b)
Present the teaching material selected in either. In addition, if the score is less than a certain score due to the condition of the exercise, the teaching material already learned is presented again, and the link information 40 in FIG.
Many variations can be realized by using 3. FIG. 23 is a configuration diagram of still another modification of the computer use education support system. FIG. 23 shows communication lines 2001 and 200.
2 is a configuration diagram of a computer network composed of four computers 2003 to 2006 connected by 2.
In this modification, a computer use education support system is linked with a plurality of computers in a computer network.

In the following description, description of functions such as mail realized by known network communication technology will be omitted. FIG. 24 is a flowchart of processing executed by each computer in the computer network of FIG. Each computer has a network management table that stores the name of each computer and the address of the computer within the network. In the computer on which the computer use education support system is started, another computer name to be linked is input (step 2101). Based on the input computer name, the address of the computer is obtained from the network management table (step 2102), and a communication path is secured with the computer (step 2103). This communication path can transfer commands and data to the partner computer or program, and is realized by ordinary network communication technology. Next, through the secured communication path, step 2102
A start instruction of the computer use education support system is transmitted to the computer of the address obtained in (step 2104).

After that, while the computer use education support system is operating on either computer, the display such as the movement of the pointing device such as the mouse, the input from the keyboard, the screen refresh, etc. is changed on both computers. Whenever an event that has a possibility to occur occurs, not only is the computer in which the event occurred perform its processing, but the event that occurred occurs is also notified to the other computer via the communication path.
(Step 2105). Further, both computers not only monitor the pointing device, keyboard, etc. attached to themselves when waiting for the occurrence of an event on their own computer, but also monitor the communication path at the same time. This allows one computer to capture the operation of the other computer.
As a result, the operation of the computer use education support system is the same on both computers. To monitor the pointing device, keyboard, etc. connected to the computer in parallel with the communication path, (a) accept interrupts corresponding to the occurrence of events from input / output devices or communication paths, and select the type of interrupt. A round-robin flag monitoring method is used, which processes correspondingly (interrupt method), and (b) periodically monitors the occurrence of an event from an input / output device or a communication path.

In step 2105, by performing the above processing, it is possible to simultaneously control the computer use education support system operating on two computers. When the use of the support system is completed in either computer through such processing, the fact is transmitted to the other computer, thereby completing the processing in both computers.
In this case, the processing is ended after opening the secured communication path (step 2106). FIG. 25 is a diagram showing an example of a screen of a display device connected to each computer in this modification. In FIG. 25, 2201 is a reduced display of the screen of another computer connected to the network, 2202 is an input device such as a keyboard, 2203 is a pointing device such as a mouse, and 2204 is a cursor. In order to realize the reduced display unit 2201 of another computer, one window may be associated with one reduced screen using, for example, a multi-window system. Also, the display position is determined in advance for each identifier of the computers connected to the network. When looking at an ordinary window system from software, one window looks like one terminal or computer.

Therefore, a computer can reproduce the same screen as the screen of its own display device on the screen of the display device of the other computer by notifying the operation of the terminal to the other computer. By using the system having such a configuration, the following educational form which cannot be realized by the conventional CAI system becomes possible. For example, the teacher uses the reduced display unit 22 on the display screen of his computer.
01 can be appropriately observed to grasp the learning progress status of the learner. Thus, for example, for a learner having a slow progress, the same display device as that of the calculator of a learner having a slow progress is displayed on the display device of the teacher's computer, and the learner and the teacher interact through the computer. You can teach and teach. For example, a normal multi-window system has a function to dynamically display a window on the screen, but when the teacher opens one window by this function, the same window is displayed on the display device of the learner's computer. Also open. Then, when the teacher appropriately inputs a character string for comment or instruction in this window, the same character string is displayed on the screen of the learner.

Further, when the learner is confused about the process of following the link displayed on the screen, the teacher can operate the computer on his / her own computer to instruct the learner. Further, since the teacher can take the learning history information 1803 of the learner into his or her computer through the network, the teacher can refer to the learning history information 1803 in accordance with the learning history information 1803 in order to more closely match the degree of understanding of the learner. Each of the above examples,
According to the modification, it is possible to provide more detailed instruction according to the learning situation of the learner, as compared with the simple presentation of mechanical review questions and the display of review materials, which has been performed by a conventional CAI system or the like. become.
