As an example of such an educational support system using a computer, an exercise problem is presented to a learner, and a score is displayed for the answer.

[0003]

The conventional educational support system has a problem that the curriculum is static. That is, since the system is generally supplied by a teaching material producing company, the curriculum is fixed, and for example, the system does not have a function of changing the teaching material according to the student's learning progress or level. This can be very difficult for some learners,
There was a problem that it was too easy. For this reason,
It is conceivable that teachers can build their own educational support systems, but it has been difficult for individual teachers to perform such programming.

[0004] The present invention has been made in view of the above circumstances, and can dynamically select learning materials in accordance with the learning progress or level of each learner, and can provide a curriculum to teachers and other instructors. It is an object of the present invention to realize an education support system that can provide an easy-to-operate interface for creating a program.

According to the present invention, a curriculum database storing a curriculum including a presentation order index of teaching materials and level information of the teaching materials, and a teaching material presentation for presenting a learning material referred to by the curriculum to a learner Means, a learning result evaluation means for receiving and evaluating the learning result for the learning material from the learner, and a presentation order index of the learning material included in the curriculum, level information, and using the evaluation received from the learning result evaluation means, There is provided an education support system having learning control means for dynamically selecting a teaching material to be presented next. According to such a configuration, the learning material to be presented next is dynamically selected according to the learning result of the learner. Therefore, it is possible to provide a learning environment according to the level of the learner.

The evaluation performed by the learning result evaluation means includes an evaluation of the learning result of the teaching material presented this time and an evaluation of the growth of the learning result between the teaching material presented in the past and the teaching material presented this time. It is desirable to be. As a result, the learning material can be selected in accordance with the learner's past learning history, so that the learner can learn the learning material to be learned more accurately.

Further, the learning control means obtains a reference value by multiplying the evaluation received from the learning result evaluation means by a weighting factor, and compares the reference value with level information of a teaching material to be provided next. Next, it is preferable to select the level of the teaching material to be provided. According to such a configuration, when a plurality of different outcomes are output from the learning outcome means, when a reference value for selecting a level of a teaching material is determined, a standard that largely reflects the outcome emphasized in the curriculum. The value can be determined.

[0008] Further, it is preferable that the educational support system further includes a teaching material creating means for creating a teaching material, and a curriculum creating means for creating a curriculum based on the created teaching material. According to such a configuration, a teaching material can be created, and a curriculum can be created based on the created teaching material.

[0009]

(Curriculum / Teaching Material Providing Unit) The curriculum / teaching material providing unit 6 (FIG. 1) is based on a request from the teaching material reader 12 provided in the learner system 2 and an instruction to select a learning material by the learning control unit 9. And has a function of sending the appropriately selected teaching material to the teaching material reader 12 for display.

(Teaching Material Reader) Teaching Material Reader 12 (FIG. 1)
Displays the contents of the teaching material through browsing software such as a browser. Through the teaching material reader 12, the learner can learn the teaching materials and can input answers to the provided exercises. The learner can use the note creator 13 as a record of his or her learning content.

(Note creating section) This note creating section 13
Has a note editor. The note editor has the same function as the teaching material editor in principle. For example, an office made by Macrosoft, various formula editors, and drawing software can be used in OLE automation. The learner can use this note editor to create graphs and the like for solving exercises.

(Learning Result Evaluation Unit) The learning result evaluation unit 7
It has a function of evaluating a learning result of a learner input through the teaching material reader 12. The evaluations performed by the learning outcome evaluation unit 7 are: (1) Evaluation within the currently processed teaching material (j) (2) Evaluation on the growth of the grade from the previously processed teaching material (j-1) (3) Current This is an evaluation of the processing time of the teaching material (j). Each evaluation will be described below in order.

[Evaluation in the currently processed teaching material] For example, it is assumed that the learner i has learned the teaching material (j) in section j following the teaching material in section j-1. It is assumed that there are n questions (k) (k = 1, 2,... N) in the teaching material (j), and the questions include small questions (s).

Here, there are different aspects of proof, calculation, and sentence as evaluation parameters (intrinsic properties of the problem) inherent in the problem included in the teaching material (j). Consider an evaluation vector. The evaluation vector includes one for each teaching material (j) and one for each question (k).

The evaluation vector of the teaching material (j) is the teaching material (section)
The evaluation vector of the question (k) indicates the property of each question (k) included in the teaching material (j).

Here, the evaluation vector Q of the teaching material (j)
_j is represented by Q _j = (Q proof _j , Q calculation _j , Q text _j ) (Q proof _j + Q calculation _j + Q text _j = 100% (an integer value in%)).

The evaluation vector V _{jk for} each question is V
_jk = (V proof _jk , V calculation _jk , V document _jk ) (V proof _jk + V calculation _jk + V document _jk = 100)
%)).

First, the point vector in question (k),
That is, the score k for each question is multiplied by V _jk , and (the score _k *
V proof _jk , score _k * V calculation _jk , score _k * V sentence _jk ) and further multiply the raw score vector, that is, raw k by V _jk , to obtain (raw _k * V proof _jk , raw score _k
* V calculation _jk , raw point _k * V sentence _jk ) are obtained.

As described above, the score vector P is obtained by the following equation. P proof _j = (Σprime point _k * V proof _jk / Σpoint score _k * V proof
_jk ) P calculation _j = (Σprimary point _k * V calculation _jk / Σcalculation _k * V proof
_jk ) P sentence _j = (Σ sentence _k * V proof _jk / Σ sentence _k * V proof
_jk ) Pj = (P proof j, P calculation j, P sentence j) where Σ is from k = 1 to n. The score vector P _j is used to evaluate the proof, calculation, and text parameters in the teaching material (j), and the total of them is 10
It is expressed so as to be 0%.

Next, when the score vector P _j is multiplied by the evaluation vector Q _j in the teaching material (j) (the inner product is taken), the evaluation of the proof, calculation, and text abilities in the teaching material (j) is evaluated. It can be obtained as a value δ _j (δ _j = Q _j · P _j ) that sums up to 100%. As described above, it is possible to obtain the evaluation in the current teaching material (j) including the questions and all the questions.

[Evaluation of Grade Growth from Previously Processed Teaching Material] In the present invention, not only evaluation in the learning material (j) but also evaluation of growth in grade from the previous learning material (j-1) is performed. In other words, the previous teaching material (previous section)
Assuming that the increase in the score from (j-1) to this section (j) is C _j , the difference between the score vectors P is calculated, and C _j = P _j −P
_j-1 .

Next, the growth C_jAnd this teaching material
Score vector Q of (j)_jMultiply by (the inner product and
). As a result, proofs, calculations,
The evaluation of each ability of the text is 100
Γ_j(Γ_j= Q _j・ C_jGet as
be able to.

[Evaluation for Processing Time] In this embodiment, the time T required for processing the teaching material (j) is T
j is also evaluated.

Then, For example, if the average processing time of the materials and TM _j, evaluation of the treatment time tau _j is, tau _j =
It is represented by Min (100 * TM _j / T _j , 100).

The learning result evaluation section 7 sends the above evaluation and the time T required for processing the question or the teaching material to the learning result recording section 8, and a KR indicated by 28 in FIG.
An evaluation message is created using the KR information stored in the information database, and is fed back to the learner system 2.

The KR information is as shown in FIG. 7 and is created by the KR information creating section 29. This KR
The information is set, for example, for each aspect of proof, text, and calculation, and stores an evaluation and a message corresponding to the evaluation. The learning result evaluation unit 7 extracts a message corresponding to the evaluation from the KR information database 28 and sends the message to the learner system 2.

(Learning Result Recording Unit) The learning result recording unit 8
Information (teaching material number) for identifying the question and the evaluation are stored in the learner database 31 shown in FIG. 1 together with the learner ID.

(Learning Control Unit) The learning control unit 9 selects the next teaching material (j + 1) to be provided to the learner according to the three evaluation values δ, γ, and τ output from the learning result evaluation unit 7. Play a function.

That is, the most important problem in the education support system is how to realize guidance according to each learner. This is because if the teaching materials can be appropriately selected and provided according to the learner's scholastic ability, motivation for the learner's learning can be increased.

Therefore, the learning control unit 9 dynamically selects a learning material (j + 1) to be provided next time by using a genetic algorithm (GA) approach.

That is, not only the learning result of the current teaching material (j), but also a dynamic evaluation is performed in consideration of the comparison with the results of the previous teaching material, the time required for processing the current teaching material, and the like. Based on this, select the teaching materials to be provided next time.

First, a reference value K _{j + 1} for selecting the next teaching material (j + 1) is obtained by using the above three kinds of evaluations.
On the other hand, for example, it is assumed that the following teaching materials (j + 1) include levels 1 to 5, and thresholds W1 to W5 for level selection are set corresponding to the levels. In this case, the level can be selected by comparing the reference value K with the threshold value W.

The reference value K _{j + 1} is obtained by the following equation. K _{j + 1} = a * τ _j + b * δ _j + c * γ _j where a ≧ 0, b ≧ 0, c ≧ 0, a + b + c = 1.

Here, a, b, and c are weighting factors. For example, when the creator of the teaching material advances the curriculum and places emphasis on the growth of the results, the value of c may be increased in comparison with other coefficients. When the processing time is important, the value of a may be increased.

The learning control unit 9 calculates the reference value Kj _{+ 1} every time a grade is input, and calculates the threshold values W1 to W5.
Then, the next teaching material α _{j + 1, m} (m: level = 1 to 5) is selected by comparing with. Such a selection method can be described using the hub type shown in FIG.

Note that the calculation in the learning control unit 9 is as shown in FIG.
Is performed with reference to the control information stored in the control information database 33 shown in FIG. This control information is created in advance by a teacher or other instructor, and includes an evaluation vector (Q,
V), the various coefficients (a, b, c, etc.), the standard processing time (TM), etc. are stored in association with the curriculum (teaching materials, questions, etc.).

(Main Screen of Authoring System) FIG. 9 shows a main screen of the authoring system. The teaching material editor button 33 is used when the teaching material editor is started to create a teaching material. The teaching material database creation button 34 is used when creating or modifying the teaching material database 18 and the curriculum database 26. The control information registration button 35 is used to register various types of control information in the control information database 33. The author registration button 36 is used for inputting a person who creates a curriculum using the authoring system or an author of a textbook to be used. The exercise question creation button 37 is used to create an exercise question.

The CMI button 38 is used for confirming the learner's learning status. For example, creation of a Time-Points table showing the processing time and the progress of the score, creation of a Time-Progress table showing the processing time of each chapter,
Stude showing the results of multiple learners in a comparable state
An nts-Problems table is created.

Also, the Mathematical button 3

The help creation button 41 is used to create a word, a term explanation, a hint, and the like in processing the teaching material in a hypertext form. The KR information button 42 is used to create the KR information.

(Flow of Curriculum Learning) On the other hand, the flow of the curriculum viewed from the learner system is as shown in the flowchart of FIG.

(1) Step S1 The learner starts the teaching material reader 12 of the learner system 2 and inputs the learner ID and the password.

(2) Step S2 Next, the teaching materials α _{j, 1 to} α of the corresponding levels W1 to W5
_The learning by _{j, 5} is started. When learning the curriculum for the first time, a preset teaching material is displayed on the teaching material reader 12. In the case where the curriculum has been studied in the past in the past, the evaluation on the last learned teaching material is taken out from the learner database, and the learning control unit 9 selects an appropriate level of the learning material by the method.

(4) Steps S5 and S6 When the learning of the teaching material is completed, it is determined whether the learning is continued or not (S6). When shifting to the next teaching material, the learning control unit 9 determines and selects the level of the learning material to be learned next by the above-described procedure (S7). Based on this, the curriculum / teaching material providing unit 6 provides the teaching material (S
2).

(5) Steps S8 and S9 On the other hand, when the learning of the teaching material is to be ended, the learning information up to that point is recorded in the learner database 31, and the processing is ended.

The present invention is not limited to the embodiment described above. For example, the parameters of the evaluation vector are not limited to the three elements of proof, calculation, and sentence. For example, a smaller number of parameters may be used, or a larger number of parameters may be used. .

Further, the reference value K _{j + 1} used for selecting the learning material in the learning control unit is determined by the evaluation δ _j in the learning material (j),
