The present invention relates to a system for supporting education, and more particularly to an education support system for supporting classes by educators and school affairs associated therewith, and an education support method using the same. The present invention also relates to a learning support system for learners and a learning support method using the same.

Traditionally, in educational settings such as school classes, as a method of evaluating the level at which students or learners such as students have mastered or understood the content of learning, in general, "tests" in which learners answer questions have been used. is carried out. In such tests, in addition to tests made by educators themselves, so-called "Vendor Tests" created by publishers according to the course of study have been used for some time. Test papers are distributed to learners who belong to a certain cluster and tests are conducted, then the collected test papers or answer sheets are graded, and the graded results are fed back to the learners.

By the way, various systems have been proposed to support educators and/or learners as the use of information communication technology (ICT) in educational settings progresses.

For example, so-called digital textbooks replace traditional paper-based textbooks by allowing educators and learners to interactively display learning content on the screens of computing devices (e.g., tablet computers) so that computing devices can be used as textbooks. make available as In computer-based testing (CBT), under the control of a computer system, learners answer questions displayed on a computer screen. It is a form of test that evaluates whether the degree has reached a certain standard.

Patent Literature 1 below discloses an education support system that enables efficient lectures by collecting and analyzing test scores. In such an education support system, educational material data such as textbook data is displayed on the first display device, a lecture is given with reference to this, and when a test related to the content of the lecture is given, answers to the test data are collected. , are analyzed, and link information indicating the answer-related parts in the teaching material data is generated and displayed on the second display device. Also, the teacher uses the link information to give further lectures.

Further, Patent Literature 2 below discloses a technique for effectively supporting the scoring of answer sheets. Specifically, the answer processing unit acquires image data of answer sheets for all the answers, extracts all answer columns and name columns as image data, associates them, and records them in the scan data DB. The aggregation output unit generates and prints out an answer collection in which only the same answer columns are extracted and aggregated. The grading processing unit acquires the grading consolidated printing output for grading, extracts it as image data, and records it. Also, the grading processing unit determines a score by identifying ◯ and × etc. added to the image data. The result output unit acquires the image data and the total score of the designated answerer (person to be printed), and prints it out as an answer sheet after grading.

The calculated statistical data can be referred to by the scoring processing unit 438, for example.

The grading processing unit 438 generates return answer data by adding specific teaching information that is considered to have a high learning effect (review effect) for the learner to the grading result data based on the learner's answer data. More specifically, the grading processing unit 438, for a specific question in the grading result data based on the answer data for each learner, according to the learner's action history data stored in the action history database 550, the teaching information database Specific teaching information is extracted from 530, and answer data for return is generated by adding the extracted specific teaching information. A specific problem to which instructional information is given is, for example, a problem in which the learner made a mistake. The teaching information includes, for example, comments on the intention of asking questions, explanatory comments on questions, recommendation comments for overcoming problems, and link information indicating specific parts in digital textbooks, supplementary teaching materials, etc. related to questions. obtain. As a result, the learner who receives the return answer data confirms his own answer sheet on the learner's terminal device 20, and if necessary, confirms the advice on the learning method for the wrong question. be able to.

In addition, the action history acquisition unit 434 may be regarded as the action history acquisition unit of the education support system 1 alone, or the action history acquisition unit 224 of the learner's terminal device 20 and / or the teacher's terminal device 30 may be regarded as an action history acquisition unit of the education support system 1 in cooperation with the action history acquisition unit 324 of 30 .

(Description of action history data acquisition processing)
FIG. 5 is a flowchart illustrating an example of action history data acquisition processing in the learner's terminal device according to one embodiment of the present invention. The processing shown in the figure is realized, for example, by the processor of the learner's terminal device 20 executing the learner's client program in cooperation with other hardware resources.

That is, as shown in the figure, the action history acquisition unit 224 of the learner's terminal device 20 monitors whether or not a predetermined event has occurred during operation (S501). The predetermined event is, for example, an operation related to reading of a specific page or learning item of a digital textbook or the like by the learner or an input for answering a practice problem. Predetermined events may also include a remote operation by a teacher to view a specific page or learning item in a learner's digital textbook or the like. Based on various operations performed by the learner on the user interface unit 230, the action history acquisition unit 224 determines whether an event such as page display of a digital textbook or input for answering a practice problem has occurred. It monitors whether an event such as page display of a digital textbook or the like from the teacher's terminal device 30 has occurred.

More specifically, when the action history acquisition unit 224 detects an event (page display event) related to page display of a digital textbook or the like, the action history acquisition unit 224 adds time information (for example, time information) to the page information indicating the page displayed based on the page display event. (S502). Further, when the action history acquisition unit 224 detects an event (exercise event) related to an input operation for answering an exercise, it generates and stores action history data in which the exercise and its answer are time-stamped. Recorded in the unit 210 (S503). Similarly, when the action history acquisition unit 224 detects another specific event, it generates action history data with a time stamp attached to the event, and records it in the storage unit 210 (S504). The action history acquisition unit 224 transmits the action history data recorded in this way to the education support server 40 at a timely timing (S505). The education support server 40 classifies the transmitted action history data for each learner and stores them in the action history database 550 .

In the above, an example in which the learner's terminal device 20 attaches a time stamp is shown, but the present invention is not limited to this. , the education support server 40 may time stamp the event when it is received.

Further, although the learner's action history acquisition processing in the learner's terminal device 20 has been described above, the teacher's action history data acquisition processing in the teacher's terminal device 30 is also performed in the same manner. In addition, the action history of the learner may be based not only on operations on the learner's terminal device 20, but also on remarks or announcements made by the learner during class, for example. For example, the teacher uses the teacher's terminal device 30 to input predetermined items as the learner's action history regarding such remarks or presentations by the learner.

FIG. 6 is a timing chart for explaining an example of action history data acquisition processing in the education support system according to one embodiment of the present invention. The figure shows how a plurality of learners perform display operations of a designated page of a digital textbook in accordance with an instruction by a teacher to display a designated page of the digital textbook.

That is, as shown in the figure, for example, at time _tn during class, the teacher verbally instructs the learner, for example, to open page Px of the digital textbook, and to display page Px, The user himself/herself operates the user interface unit 330 of the teacher's terminal device 30 . In response, the teacher's terminal device 30 acquires the page display event _ET1 , adds a time stamp _tn +δ1 to it, records it, transmits it to the education support server 40, and displays it on the user interface unit 330. Display the page Px. On the other hand, learners A and B operate the user interface unit 230 of their own learner terminal devices 20 at respective timings in order to display the page Px in response to instructions from the teacher. In response to this, the learner terminal device 20 of the learner A acquires the page display event _EA1 , adds a time stamp t _n + δ1 to it, records it, transmits it to the education support server 40, and The page Px is displayed on the interface section 230 . Similarly, the learner's terminal device 20 of the learner B acquires the page display event _EB1 , adds a time stamp t _n + δ2, records it, transmits it to the education support server 40, and the user interface unit 230 Display the page Px on top.

Note that the values of the time stamps for the events of learners A and B differ due to differences in operation timing in real time. ), the education support server 40, for example, based on the time stamp of the event corresponding to the teacher, rounding the value by a predetermined unit time (for example, 30 seconds, 1 minute, 2 minutes, etc.) good.

Next, at time tn ₊₁ , the teacher instructs the learner to open page Py of the digital textbook, and similarly performs a display operation for page Py. In response to this, the teacher's terminal device 30 generates a page display event _ET2 , adds a time stamp tn ₊₁ to it, records it, transmits it to the education support server 40, and displays it on the user interface unit 330. Display page Py. At this time, it is assumed that the learner A receives the teacher's instruction and operates the user interface unit 230 of the learner's terminal device 20 without delay to display the page Py. In response to this, the learner terminal device 20 of the learner A generates a page display event _EA2 , adds a time stamp t _n+1 +δ1 to it, records it, transmits it to the education support server 40, and The page Px is displayed on the interface section 230 . On the other hand, it is assumed that learner B refers to page Px without switching the display to page Py regardless of the teacher's instruction. Therefore, the learner's terminal device 20 of the learner B does not generate a page display event at this point.

Further, it is assumed that although learner A switched to page Py according to the teacher's instruction, he again performs a display operation of page Px. In response to this, the learner terminal device 20 of the learner A generates a page display event _EA3 , adds a time stamp t _n+1 +δ2 to it, records it, transmits it to the education support server 40, and The page Px is displayed on the interface section 230 . In this case, if the display time of the page Py on the learner's terminal device 20 of the learner A is equal to or longer than a predetermined threshold time, the page Py is considered to be displayed and/or synchronized with the teacher's page display. shall be deemed to have

Next, at time tn ₊₂ , the teacher instructs the learner to open page Pz of the digital textbook, and performs a display operation for page Pz. In response to this, the teacher's terminal device 30 generates a page display event _ET3 , adds a time stamp tn ₊₁ to it, records it, transmits it to the education support server 40, and displays it on the user interface unit 330. Display page Pz. The learners A and B operate the user interface section 230 of their own learner terminal devices 20 at substantially the same timing in response to instructions from the teacher. In response to this, the learner terminal device 20 of the learner A generates a page display event E _A4 , adds a time stamp t _n+2 +δ1 to it, records it, transmits it to the education support server 40, and The page Pz is displayed on the interface section 230 . In addition, the learner's terminal device 20 of the learner B generates a page display event _EB2 , adds a time stamp t _n+2 +δ1 to it, records it, transmits it to the education support server 40, and the user interface unit 230 Display the page Pz on top.

As described above, events occurring in the learner's terminal device 20 and the teacher's terminal device 30 are transmitted as action history data to the education support server 40, and the education support server 40, for example, as shown in FIG. The transmitted action history data is stored in the action history database 550 for each user. Note that, as described above, the timestamp value may be a value rounded to a predetermined unit time (eg, 30 seconds, 1 minute, 2 minutes, etc.) in consideration of differences in operation timing in real time. good. Also, as described above, an event may be considered not to have been generated if the time until the next event is less than a predetermined threshold time.

(Description of scoring process)
FIG. 8 is a flow chart for explaining scoring processing in the education support server according to one embodiment of the present invention. The processing shown in the figure is realized, for example, by the processor of the education support server 40 executing a scoring processing program in cooperation with other hardware resources.

The grading processing unit 438 of the education support server 40, for example, upon receiving a grading processing request from the teacher's terminal device 30, extracts learners to be graded (S801). A learner to be graded is, for example, a learner who has taken a predetermined test among the learners in charge of the teacher. Although not shown, the scoring processing unit 438 terminates the processing when the learner to be graded cannot be extracted, for example, assuming that an error has occurred. Next, the grading processing unit 438 selects one learner from among the extracted learners (S802), and reads the grading result data of the selected learner from the performance management database 540 (S803). The grading result data is data in which grading attributes of correctness (including partial correctness or partial demerit points, etc.) are associated with each question of the learner's answer data. Grading attributes are associated, for example, when a teacher inputs grading using the teacher's terminal device 30 .

Next, the grading processing unit 438 adds teaching information to the read grading result data based on the action history data of the learner, and generates answer data for return (S804). The details of the teaching information addition process will be described later.

After generating the return answer data, the grading processing unit 438 determines whether or not the above grading process has been performed for all the learners to be graded (S805). When the scoring unit 438 determines that the above scoring process has not been performed for all learners (No in S805), the process returns to S801 to select the next learner. On the other hand, if the grading processing unit 438 determines that the above grading processing has been performed for all learners (Yes in S805), the processing ends.

FIG. 9 is a flowchart for explaining teaching information imparting processing in the education support server according to an embodiment of the present invention, and more specifically, a flowchart showing details of step S804 shown in FIG.

That is, as shown in the figure, the scoring unit 438 refers to the action history database 550 and reads action history data of the selected learner (S901). In this case, the scoring processing unit 438 can refer to the time stamp of the action history data and extract action history data within a predetermined learning period associated with the test. Next, the scoring unit 438 analyzes the extracted action history data and classifies the action history data into subsets for each learning item (S902). For example, if each learning item is associated with, for example, a predetermined page of a digital textbook, the grading processing unit 438 selects each event in the action history data according to the page number indicated in the content of the event in the action history data. are classified according to learning items.

Next, the grading processing unit 438 sequentially selects one test question according to the learner's grading result data (S903), and determines whether or not the learner's answer to the question was correct (S904). . In this example, when the grading processing unit 438 determines that the answer to the question is correct (Yes in S904), feedback to the learner is unnecessary, so the process returns to S903 and selects the next question. . On the other hand, if the grading processing unit 438 determines that the answer to the question was incorrect (No in S904), it refers to the test question database 520 and identifies the learning item associated with the question. (S905).

Subsequently, the scoring unit 438 evaluates the learning status of the learner based on the action history data corresponding to the specified learning item (S906). For example, the scoring processing unit 438 determines whether or not there is a subset (event) of action history data corresponding to the specified learning item. is evaluated as unlearned. Also, even if there is a subset of action history data corresponding to the learning item, the scoring unit 438 determines that the accumulated display time (the time from the start time of an event to the start time of the next event) does not exceed the predetermined threshold value. Even when it is determined that the time is less than the time, the learning situation of the learner can be evaluated as unlearned. The learning status may be indicated by a level corresponding to the accumulated time instead of the binary value of learned or unlearned.

The scoring unit 438 then refers to the teaching information database 530 based on the evaluation result of the learning situation, and extracts at least one appropriate teaching information item (teaching item) for the question (S907). , the extracted teaching item is given to the question in the scoring result data as teaching information (S908). Instruction information includes, for example, items such as comments on the intention of asking questions, explanatory comments on questions, recommendation comments for overcoming problems, and link information indicating specific parts in digital textbooks and supplementary teaching materials related to questions. including. As an example, if the evaluation result indicates that the subject has not been learned, the grading processing unit 438 provides link information or the like indicating a specific part in a digital textbook or supplementary teaching material related to the question as instruction information. As another example, if the evaluation result indicates that learning has been completed, the grading processing unit 438 adds a recommendation comment for overcoming the problem in addition to a comment regarding the intention of asking the question and an explanation comment for the question. It is given as teaching information.

After adding teaching information to the grading result data, the grading processing unit 438 determines whether or not the above processing has been performed for all questions (S909). (No in S909), the process returns to S903. On the other hand, if the grading processing unit 438 determines that all the questions have been processed (Yes in S909), it assumes that the generation of the learner's return answer data has ended, and sends the return answer data to the grade management database 540. , and terminates the teaching information assignment process.

Each learner's return answer data stored in the grade management database 540 is referred to, for example, on the learner's terminal device 20 . For example, the learner operates the interface unit 230 on the learner's terminal device 20 in order to confirm the graded answer of the test that the learner has taken. In response to this, the test result display control unit 226 of the learner's terminal device 20 requests the education support server 40 to return the answer data, and the education support server 40 sends the answer data for return from the grade management database 540 to the learner. Answer data is extracted and transmitted to the terminal device 20 for learners. The learner terminal device 20 receives the return answer data, and the test result display control unit 226 displays the scored answer sheet (return answer sheet) on the user interface unit 230 based on the return answer data. ) is displayed.

FIG. 10 is a diagram showing an example of a return answer sheet displayed on the learner's terminal device in the education support system according to one embodiment of the present invention. As shown in the figure, the return answer sheet 1000 is displayed on the browser screen of the learner's terminal device 20, for example. Return answer sheet 1000 may include annotations 1010, for example. An annotation 1010 indicates that the question is given teaching information. For example, when the learner taps the annotation 1010, the learner's terminal device 20 displays teaching information given to the question in a pop-up window. In this example, a display example on the learner's terminal device 20 has been described, but the present invention is not limited to this, and the teacher can use the teacher's terminal device 30 to check the return answer sheet of the learner. can.

In this way, teaching information is added to questions with incorrect answers on the return answer sheet, and the learner can know that teaching information has been added from the annotation 1010 . Also, by tapping the annotation 1010, the learner can check the teaching information given to the question, and can proceed with learning according to the teaching information.

In this example, when the answer to the question is correct, it is considered that the learner understands the question, so the grading processing unit 438 does not add teaching information, but is not limited to this. For example, even if a question is answered correctly, the scoring unit 438 may be configured to add a comment regarding the intent of asking the question so that the learner can reconfirm the question. As another example, even if the answer to the question is correct, the scoring unit 438 evaluates the learning situation based on the learner's action history data, and provides optimal teaching according to the evaluation result. It may be configured to provide information.

[Second embodiment]
In this embodiment, which is a modification of the above-described first embodiment, regarding the questions of the test taken by the learner, the synchronization state based on the action history of the learner himself and all learners and the correct answer rate of all learners Based on, a technique is disclosed in which appropriate teaching information is given to an answer. The synchronization state is typically determined based on whether or not the individual learner displays a predetermined page of the digital textbook in synchronism with the teacher's display of the predetermined page during class. That is, in the first embodiment described above, teaching information is given based on the action history of whether or not the learner has displayed (browsed) a predetermined page. This differs from the first embodiment in that information such as the synchronization state and the rate of correct answers to questions is taken into consideration. As a result, individual learners can receive more detailed teaching information.

FIG. 11 is a diagram showing an example of teaching information provision rules in the education support server according to one embodiment of the present invention. That is, as shown in the figure, according to the teaching information provision rule 1100 of the present embodiment, what kind of teaching information is provided based on the overall synchronization state 1110, the learner's synchronization state 1120, and the correct answer rate 1130. A table or data structure that defines rules about what to do.

More specifically, the overall synchronization status 1110 is indicated as either "synchronized" or "unsynchronized" based on, for example, the synchronization rate of all learners in the class being taught by the teacher. For example, in the class, the percentage of the number of learners who displayed the page in sync with the page displayed by the teacher (synchronization rate) exceeds a predetermined threshold (eg, 80%, 90%, etc.) If so, the overall sync state 1110 is considered to be "sync." A learner's sync status 1120 is indicated as either "sync" or "out of sync" based on the learner's own rate of sync with the teacher. The correct answer rate 1130 is, for example, the correct answer rate of all learners in the class targeted by the teacher, and the correct answer rate is high or low based on a predetermined threshold (eg, 60%, 70%, 80%, etc.) are distinguished by either

As an example, for a question that a certain learner answered incorrectly, all the learners were in sync, and the learner was also in sync, but the correct answer rate was low. Since it is considered that the learner's understanding was insufficient, teaching information that recommends referring to the corresponding page (learning item) of another teaching material with a lower difficulty level is selected. As another example, for a question that a certain learner answered incorrectly, all the learners were in sync, but the learner was asynchronous, and if the correct answer rate was high, the learner had not learned. Therefore, teaching information that recommends reference to the corresponding page of the basic teaching material (digital textbook) is selected again.

Note that the teaching information provision rule may be configured, for example, to simply provide teaching information based only on the synchronization state of the learner, or the combination of the synchronization state of the learner and the overall synchronization state You may be comprised so that teaching information may be provided based on. Alternatively, the teaching information provision rule may be configured to provide teaching information based on a combination of the learner's synchronous state and correct answer rate.

FIG. 12 is a flow chart for explaining scoring processing in the education support server 40 according to one embodiment of the present invention. The scoring process shown in FIG. It is different from the scoring process shown in .

Referring to FIG. 4, the grading processing unit 438, for example, upon receiving a grading processing request from the teacher's terminal device 30, extracts learners to be graded (S1201). Subsequently, the grading processing unit 438 calls the statistical processing unit 436 to acquire the overall synchronization rate and the overall correct answer rate for the test questions (S1202). That is, when the test grading process starts, the statistical processing unit 436 calculates the synchronization rate of all learners for each question (overall synchronization rate ), and the correct answer rate (overall correct answer rate) of all learners for each question is calculated. For example, the statistical processing unit 436 refers to the action history database 550 for learning items (digital textbook pages) associated with each test question, determines the synchronization status of each learner, and determines the synchronization status of all learners. By calculating the rate and comparing it to a predetermined threshold, the overall synchronicity of the learners is determined. In this sense, the statistical processing section 436 functions as a synchronization state determining section. In addition, the statistical processing unit 436 counts the number of learners who gave correct answers for each test question, and calculates the ratio of how many learners answered correctly to the total number of learners. In this sense, the statistical processing section 436 functions as a correct answer rate calculating section. The calculated overall synchronization rate and overall correct answer rate are referred to when providing teaching information.

Subsequently, the grading processing unit 438 selects one learner and performs a process of adding instruction information to the grading result data of the learner (S1203 to S1207). These processes are the same as those shown in FIG. 8, except for the specific processing contents in the teaching information addition process of S1206, so description thereof will be omitted.

The teaching information imparting process in this embodiment will be explained using the flowchart shown in FIG. Furthermore, in the process of step S907, the scoring processing unit 438 extracts teaching information from the teaching information database 530 according to the teaching information provision rule 1100, which is different from the first embodiment.

That is, the scoring unit 438 evaluates the learner's learning status based on the action history data corresponding to the learning item for the question, and determines the learner's synchronous state (S906). For example, the grading processing unit 438 determines whether it is “synchronous” or “asynchronous” according to a subset (event) of teacher and learner action history data corresponding to the learning item. Next, the grading processing unit 438 extracts recommendations for the question from the teaching information database 530 according to the teaching information provision rule 1100 based on the overall synchronization state, the overall percentage of correct answers, and the learner's synchronization state.

As described above, according to the present embodiment, appropriate teaching information corresponding to the action history and correct answer rate of all learners and the action history of the learner himself/herself is added to the answer for the question that the learner answered incorrectly. will be able to Therefore, this enables individual learners to receive more detailed teaching information.

[Third Embodiment]
This embodiment, which is a modification of the second embodiment, discloses a technique for providing teaching information to a teacher regarding test questions taken by a learner. That is, the above embodiment provides teaching information to the learner, but this embodiment provides teaching information to the learner and also provides teaching information to the teacher. This is different from the above embodiment in this point. As a result, for example, it is possible to expect improvement in the teacher's teaching method for problems with a low percentage of correct answers.

FIG. 13 is a diagram showing an example of teaching information provision rules for teachers in the education support server according to one embodiment of the present invention. That is, as shown in the figure, the teaching information provision rule 1300 of this embodiment is a table or data structure that defines rules regarding what kind of teaching information should be provided for teachers.

More specifically, according to the teacher's teaching information provision rule 1300, as an example, all learners were in sync with a question that a learner answered incorrectly, and the learner was also in sync, but the correct answer rate was If it is low, teaching information that recommends improvement of the teaching method in class is selected. The improvement of the teaching method is, for example, the recommendation of supplementary lectures using different teaching materials. As another example, regarding a question that a certain learner answered incorrectly, all learners and the learner are asynchronous, and if the correct answer rate is low, many of the learners in class are not concentrating on the main topic. Therefore, teaching information that recommends improvement of the teaching method so that the learner's concentration can be directed to the lesson is selected.

The learner's return answer data to which the teaching information is added for the teacher in this way can be displayed as a return answer sheet on the user interface unit 330 of the teacher's terminal device 30, for example. The teacher can check the teaching information for the learner and the teaching information for the teacher on the return answer sheet displayed on the user interface unit 330 of the teacher's terminal device 30 . This enables the teacher to know what kind of instruction should be given, for example, for questions with a low percentage of correct answers.

As described above, according to the present embodiment, a teacher is recommended to improve the teaching method for a question that the learner answered incorrectly, based on the overall action history and correct answer rate and the learner's action history. and can give feedback to teachers on test results.

Each of the above embodiments is an example for explaining the present invention, and is not intended to limit the present invention only to these embodiments. The present invention can be embodied in various forms without departing from the gist thereof.

For example, in the methods disclosed herein, steps, actions or functions may be performed in parallel or in a different order without conflicting results.
