Further, a learner file 40 updated by the learning level update unit 23 and a learning situation file 50 referred to by the next screen selection unit 24 are connected to the CAI 20.
[0005]
FIG.7These are figures which show the contents of a learner file. As shown in the figure, the learner file 40 holds the student ID and the level of the student for each learning item for each student ID.
FIG.8These are figures which show the content of the learning condition file. As shown in the figure, the learning status file 50 includes a learning precondition for displaying a learning screen and a learning level of the learner when the problem displayed on the screen is 100 points. The change value of (understanding level) is shown, and when it is 50 points, it is an intermediate value.
[0006]
As the CAI management function, the student's learning level, learning preconditions, and learning effects are respectively managed, and the learning level (degree of understanding) for each student is stored for each learning item. Each of these pieces of management information is given a learning precondition that indicates the level of understanding that the learner must reach in order to display a certain learning screen in response to the problem for each screen, and the answer to the teaching material has been completed. The learning effect is also managed at that time. In this way, the CAI selects a plurality of screens that match the learning prerequisites from the learner's learning level, and selects the screen having the highest learning effect from among them.
[0007]
In this learning support system, the student displays the teaching material provided in a stand-alone manner on the screen, learns by viewing the teaching material on the screen, or answers a question displayed on the screen. The teacher side acquires and manages only the progress information of the students via the LAN.
[0008]
If there is a question from the student to the teacher, the student calls the teacher or makes a videophone call and verbally tells the teacher the screen corresponding to the question. Both the teacher PC 10 and the student PC 21 The screen is displayed on the screen, and questions and answers are made over the phone while viewing the screen.

As a result, the question analysis unit 140 reads the question storage unit 170, sorts the question information by title, and totals the number of questions for each title. Therefore, if a title with a large number of questions is extracted and the student of the title has a low level of understanding, it is determined that the title (educational item) should be considered, and a list for making various revisions. Is generated.
[0060]
Further, as statistical processing, it is possible to refer to the understanding level data and learning effect data of all students, calculate an average score and an average score for each student, and transmit the average score to each student via the mail system 120. .
As described above, according to the fourth embodiment, it is possible to extract teaching materials and teaching material contents with a large number of questions and use them for revision of the teaching materials.
[0061]
[Fifth embodiment]
Next, as a fifth embodiment, comprehension data is obtained from each student PC, the comprehension data is aggregated, the average score and the rank for each student are analyzed, and each student PC is analyzed. An example of transmission is shown. At this time, it is assumed that the question storage unit 170 stores not the question but the understanding level data acquired from the student PC.
[0062]
FIG. 14 shows the configuration of the question analysis unit of the teacher PC according to the fifth embodiment of the present invention. In the same figure, the totaling unit 191 reads the comprehension data stored in the question accumulation unit 170 as a pre-process for calculating the average score, and totals the points. Next, the average score calculation unit 192 calculates an average score based on the total score and the number of received data. Further, the rank determining unit 193 determines the rank for each student, and outputs it to the mail system 123 of the communication control unit 120. As a result, the mail system 120 delivers the average score and rank data for each student.
