Description

  The present invention relates to a technique for presenting teaching materials in an appropriate order, for example, in e-learning, mobile learning, and the like, and in particular, a teaching material for selecting and presenting teaching materials in an order that continues the interest of the learner. The present invention relates to a presentation order control apparatus and the control program.

  Presenting learning materials such as words to be memorized, sentences, sentences, tasks to be learned, problems to be solved, etc. to the learner in an appropriate order is to maintain the learner's motivation and ensure the learning effect. Is important to.

  For example, rather than continuously presenting problems that are completely unrelated to each other, it is thought that the learning effect is greater when the related problems are presented continuously because the learner can easily obtain the outline. On the other hand, it is easy to get bored only with related problems.

  Therefore, it is desirable that the teaching material provider has a high degree of freedom in setting the presentation order so that related problems can be presented continuously, and sometimes unrelated problems can be presented continuously. In addition, it is desirable to realize problem selection control as easily as possible.

  Conventionally, the presentation order of such teaching materials is determined manually in advance, or the problem to be presented is selected at random. There is a problem that it is difficult and efficient to manually determine the presentation order of teaching materials, and the degree of freedom in setting the presentation order is inferior. When selecting a problem at random, it is possible to put restrictions such as for each field, but it is also impossible to present the problem in an order that takes into account the relationship between the problems.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a teaching material presentation order control apparatus and a computer program that can appropriately perform the presentation order setting automatically and without maintaining the learner's interest. .

  Another object of the present invention is to provide a teaching material presentation order control device and a computer program that have a high degree of freedom in setting the presentation order and can be automatically performed so as to maintain the interest of the learner. It is to be.

  A teaching material presentation order control device according to an aspect of the present invention provides an initial teaching material selection means for selecting one of a plurality of teaching materials based on a predetermined initial selection condition, and a correlation between the plurality of teaching materials. And a next teaching material selecting means for sequentially selecting teaching materials to be presented subsequent to the teaching material selected by the initial teaching material selecting means based on the relevance degree table storing the degrees.

  The selection means selects the next learning material to be presented following the previous learning material based on the relevance level table. Since the relevance table can be automatically created, the teaching material presentation order is automatically set without human intervention, which is efficient and leads to cost reduction. In addition, by appropriately modifying the contents of the table, the presentation order can be freely set, so that the degree of freedom in setting the presentation order can be significantly improved.

  In the above teaching material presentation control device, the selecting means is a means for selecting, as the next teaching material, a teaching material having a relevance degree satisfying a predetermined condition with the previously presented teaching material based on the relevance level table. May be included.

  Next, a teaching material having a relevance degree satisfying a predetermined condition with the presented teaching material is presented. A predetermined relationship is established between the teaching materials continuously presented, and the learner's interest can be maintained.

  The same applies to the case where the selection means selects the teaching material whose degree of association with the previously presented teaching material satisfies the predetermined threshold as the next teaching material based on the relevance level table. An effect is obtained.

  In addition, a counter for recording the number of presentations of each learning material is further included, and the selection means includes a means for selecting the next learning material from the learning materials for which the number of presentations recorded by the counter does not reach a certain value. Also good.

  The teaching material whose count value has reached a certain value is no longer selected, and the same teaching material can be prevented from being repeatedly presented.

  The possible values of the relevance level of the teaching materials include a predetermined first value and a second value different from the first value. When the teaching materials satisfy the predetermined relationship, the relevance level of both teaching materials Is the first value, the degree of relevance is the second value when it is not satisfied, and the selection means uses the learning material having the first value as the degree of relevance with the previously presented learning material as the next learning material. Means for selecting may be included.

  Since the teaching materials with the first relevance level are presented continuously, if a relevance level table is prepared in advance so that the relevance level of the teaching materials with an appropriate relevance is the first value, the teaching material is automatically The teaching materials that have the appropriate relationship with each other will be presented continuously.

  Regarding whether or not two teaching materials are related, for example, when the teaching material is a problem of presenting a word, when the last letter or pronunciation of one of the two words is the same, or When two words are synonymous, synonymous, anomaly, or when there is a derivation relationship between the two words, or when the translation of the two words is the same, the relevance of both materials is the first value, otherwise There is a method of setting the second value.

  In addition, the teaching material is a problem of presenting a sentence, and the relevance between any two teaching materials may be indicated by a predetermined similarity calculated between sentences constituting each teaching material, for example, the Tanimoto coefficient. Good.

  Based on the relevance indicated by the similarity, the teaching material presentation order is determined so that sentences similar to each other continue.

  In addition, a predetermined symbol is provided instead of the relevance level in an arbitrary part of the relevance level table, and the selection unit is detected in the relevance level table as the relevance level corresponding to the previously presented teaching material. Based on the symbol, a process different from the selection of the next teaching material may be executed. With this symbol, it is possible to stop the continuous presentation of the learning material and insert another process, or end the presentation of the learning material.

  A computer program according to another aspect of the present invention is a computer program that, when executed by a computer, causes the computer to operate as one of the above teaching material presentation order control devices.

  The embodiment of the present invention described below is realized by a computer and software operating on the computer. Of course, part or all of the functions described below can be realized by hardware instead of software.

[Description of device]
FIG. 3 is a block diagram functionally showing the program of the present embodiment as a teaching material presentation order control device 80. Referring to FIG. 3, N teaching materials Ii (iε {0, 1,..., N−1}) are stored in advance in hard disk 54. Furthermore, the degree of association RijεR between the teaching materials Ii and Ij is calculated in advance, tabulated as a degree-of-association table 100 between the teaching materials Ii and Ij, and stored in the hard disk 54. An example of the relevance table is shown in FIG. The association degree table will be described later with reference to FIG.

  The teaching material presentation order control device 80 includes an initial teaching material selection unit 81 for selecting a teaching material to be presented first from the teaching materials stored in the hard disk 54, a problem currently selected and presented to the learner, Based on the relevance table stored in the hard disk 54, the teaching material to be presented next to the learner and not presented for a predetermined number of times (n times) is selected and given to an output unit (not shown). And a counter 83 used when the next teaching material selection unit 82 counts the number of times the teaching material is presented.

  Referring to FIG. 4, in the present embodiment, relevance degree table 100 stored in hard disk 54 is in a matrix format of N rows and N columns. In FIG. 4, the number of the teaching material presented first (Mth) in the column direction (vertical direction), and the number of the teaching material presented next (M + 1) in the row direction (horizontal direction). It is shown. That is, in the i-th row and j-th column of the relevance level table 100, the value of the relevance Rij between the two teaching materials Ii (the teaching material presented first) and Ij (the teaching material presented later) is stored. In the present embodiment, the relevance level Rij is set to 1 when the teaching materials Ii and Ij are related, and the relevance level Rij is set to 0 when they are not related.

  In the example shown in FIG. 4, each educational material has a relevance level of 1 with itself, but this value can be 0 or 1 depending on the definition of the relevance level. When the degree of association with one is 1, there is a risk that an infinite loop may occur by selecting one after another.

  In this embodiment, each teaching material Ii assumes a problem in which a foreign language word to be studied is given and the translation is asked. The so-called siritri method is used as the degree of relevance of the learning material, and the character (or pronunciation) at the end of the learning material (word) Ii matches the first character (or pronunciation) of the learning material (word) Ij out of the two words. If the two are related to each other, the degree of association Rij is set to 1 and the values are set to 0 if they do not match.

  Further, for example, when learning is to be ended with a specific learning material (for example, learning material Ij), all values of relevance Rjx (x is an arbitrary number from 0 to N−1) are set to −1. When the teaching material Ij is selected as the teaching material to be presented next with reference to the table 100 after the previous teaching material Ii is presented, the degree of relevance corresponding to this teaching material Ij is all −1, so the learning is forced by the teaching material Ij. End automatically. That is, in this embodiment, the degree of association −1 is used as a stop symbol.

  Of course, the stop symbol is not limited to −1, and the values of one line may not be all −1, and only one specific degree of association may be −1. In this case, after the degree of relevance 1 or -1 is identified and the next learning material is selected, the processing may be terminated when the relevance level of the selected learning material is -1.

  In addition, a specific identification symbol other than 0 or 1 is appropriately written instead of the relevance level Rij, and when the identification symbol is selected, the content for breathing (eg animation) is temporarily presented. Later, a learning material corresponding to the identification symbol may be selected to return to learning.

  As another method of setting the relevance level during word learning, refer to the thesaurus, and when the two words Ii and Ij are synonymous, synonymous, or affirmative, the relevance Rij is set to 1; May be set to 0. In addition, referring to the word dictionary, when there is a derivation relationship (for example, a relationship between an adjective and a noun) between the two words Ii and Ij, the degree of association Rij may be set to 1, otherwise it may be set to 0. Good. Also, referring to the bilingual dictionary, when the bilingual translation of the two words Ii and Ij is the same (for example, when the Japanese translation is the same with respect to English), the relevance level Rij of both teaching materials may be set to 1, and the others may be set to 0. .

  The initial learning material selection unit 81 selects an initial learning material from the learning materials Ii stored in the hard disk 54. In this embodiment, the initial teaching material is selected appropriately (for example, by random numbers) from the genre problems specified by the user.

  When the initial learning material is selected by the initial learning material selection unit 81, the next learning material selection unit 82 has a function of referring to the relevance level table 100 and selecting and determining the subsequent teaching material. Specifically, in accordance with a predetermined condition, the presentation order of the teaching materials is determined with reference to the relevance table 100 shown in FIG. For example, under the condition that a learning material having a relevance level Rij of 1 is presented, a learning material having a relevance level of 1 is searched from the Ii row of the relevance level table for the learning material Ii given as the initial learning material. For example, if the degree of association between the teaching materials Ii and Ij or the teaching materials Ii and Ik is 1, either Ij or Ik is selected as the teaching material to be presented next. If there are a plurality of teaching materials with a relevance level 1, they may be set in advance so that they are selected in descending order or ascending order, or randomly selected. When a learning material having a relevance of −1 is selected, the process is terminated at that point. If you want to stop learning as soon as possible for some reason, pre-read the degree of association with the next teaching material for a plurality of teaching materials with a relevance level of 1, and select the teaching material with a pre-read relevance level of -1. You may do it.

  When the next teaching material selection unit 82 selects the teaching material Ik and outputs it, if there is a teaching material Im having a relevance level Rkm of 1 in the row direction from the position of Ik in the column direction, this is used as a teaching material to be presented next. select. When there are a plurality, the next problem is selected according to some selection condition as described above. The same applies hereinafter.

  The counter 83 counts the number of times selected as the next teaching material to be presented next by the next teaching material selection unit 82, in other words, the number of times presented for each teaching material in the counter table 110 as shown in FIG. . In the present embodiment, the teaching material whose number of selections (presentation number) has reached a predetermined number (n times) is no longer selected as the next presentation material. With this configuration, consideration is given to avoiding only the same teaching materials being presented in a biased manner.

[Program control structure]
Next, a control structure of a program for realizing the function of the teaching material presentation order control apparatus 80 shown in FIG. 3 using a computer will be described with reference to the flowchart of FIG.

  First, in step 202, the initial teaching material Ii is selected according to a predetermined selection method. The selected initial teaching material is transmitted to the output unit in step 204, and further transmitted from the output unit to a personal computer, a mobile device, etc. and presented to the learner.

  Next, it is searched with reference to the relevance level table 100 whether or not there is a relevance level 1 learning material for the initial learning material Ii (step 206). If there is a learning material having a relevance of 1 with respect to the initial learning material Ii (YES at step 206), the process proceeds to step 208. If not (NO at step 206), the process proceeds to step 216.

  In step 208, if there are a plurality of teaching materials having a relevance level 1, one of them is selected according to some selection method. Thereafter, the process proceeds to step 210.

  In step 210, it is determined from the counter table 110 whether or not the learning material with the relevance level 1 (referred to as learning material Ij) selected for the initial learning material Ii has already been presented n times or more. If this learning material Ij has been presented n times or more (YES at step 210), the process returns to step 206, and the next candidate that has a relevance level of 1 with the learning material Ij is searched using the relevance level table 100. If the teaching material Ij has not been presented n times or more (NO at step 210), this teaching material Ij is selected as the next teaching material (step 212) and transmitted to the output unit (step 214). Then, returning to step 206, in order to select the next presented learning material, a learning material having a relevance of 1 with the learning material Ij is searched. Thereafter, the same processing is repeated, and related teaching materials are presented in a serial format.

  On the other hand, in step 216, it is determined whether or not all the relevance levels stored in the row corresponding to the problem presented immediately before in the relevance level table 100 are −1. If all the relevances are −1 (YES at step 216), the process is forcibly stopped (step 218). If all the relevance levels are not -1 (NO in step 216), the relevance level is all 0 and there is no related learning material, so the process returns to step 202 and the process is restarted from the selection of the initial learning material.

[Operation]
The above-described teaching material presentation order control device 80 operates as follows. Referring to FIG. 3, first, a teaching material and a relevance level table 100 are prepared on the hard disk 54. In response to a request from the learner, the initial learning material selection unit 81 selects the first learning material from the learning materials stored in the hard disk 54 and gives it to the output unit and the next learning material selection unit 82.

  Based on the number of the learning material given from the initial learning material selection unit 81, the next learning material selection unit 82 determines the relevance level stored in the row corresponding to the learning material in the relevance level table stored in the hard disk 54. It is determined whether or not there is one that becomes 1. If there is only one that becomes 1, the next learning material selection unit 82 once selects the learning material corresponding to the column in which the degree of association 1 exists as the next learning material. When there are a plurality of relevance levels of 1, the next teaching material selection unit 82 selects one of them according to a predetermined selection method, and selects the teaching material corresponding to the column having the relevance level as the next teaching material. As once selected.

  The next teaching material selection unit 82 further determines with reference to the counter 83 whether or not the teaching material once selected in this way has been selected (presented) n times or more. If the selected number is n times or more, the presentation of this teaching material is stopped. If less than n times, this learning material is selected and given to the output unit, and 1 is added to the count of the counter 83 corresponding to this learning material.

  Next, regardless of whether or not it is actually selected, there is one that is 1 in the relevance stored in the row corresponding to the learning material selected as the next learning material candidate by the next learning material selection unit 82. Is determined with reference to the relevance table 100. Thereafter, the next teaching material is selected according to the same method as described above.

  When all the values stored in the row corresponding to the selected learning material in the relevance table 100 are −1, the learning material presentation order control device 80 stops the process and the problem presentation ends. At this time, a message indicating that the presentation of the problem has ended may be sent to the learner via the output unit.

  The above is the outline of the operation of the teaching material presentation order control apparatus 80.

  In the embodiment shown in FIG. 6, a learning material with a relevance level of 1 is selected as a teaching material to be presented next, but a learning material with a relevance level of 0 may be selected as the next learning material. In this case, irrelevant teaching materials are presented before and after. The degree of relevance is not limited to 0 and 1, but a multi-stage value may be used.

In the above-described embodiment, when the selected teaching material candidate has been presented n times or more, the teaching material is not presented. However, the teaching material presented even once is the next presented teaching material. It is good also as a setting which is not selected as. In this case, each teaching material is presented only once, and many types of teaching materials can be presented.
[Other embodiments]
FIG. 7 shows an association degree table according to another embodiment of the present invention. The relevance level table 120 shows a case where the teaching material Ii is a sentence, and the relevance level is calculated by a Tanimoto coefficient.

  The Tanimoto coefficient is a value obtained by dividing the product set size (number of elements) of the constituent words of the teaching material Ii sentence and the teaching material Ij sentence by the union size (element number). Specifically, when the two teaching materials are, for example, a sentence “Do you have the time?” And a sentence “Do you have time time?”, The union of the constituent words is “Do”, “you”, “ “have”, “the”, “time”, the number of elements is 5, the product set is “Do”, “you”, “have”, “time”, and the number of elements is 4. Therefore, the Tanimoto coefficient is 4/5. The similarity of sentence contents can be expressed by the Tanimoto coefficient. When the Tanimoto coefficient is 1, the degree of similarity is maximized and can be regarded as a sentence close to synonym. Tanimoto's coefficient is 1 with itself. In this case, as shown in FIG. 4, there is a risk of falling into an infinite loop that repeats itself, and it is necessary to take measures to prevent it.

  Also in the relevance level table 120, the relevance level -1 may be intentionally set at an arbitrary location in order to forcibly stop the teaching material presentation.

  Even when this relevance degree table 120 is used, the apparatus 80 of the first embodiment can be used as it is. When the initial learning material is selected by the initial learning material selection unit 81, the next learning material selection unit 82 selects and determines the learning material to be presented subsequently. Specifically, in accordance with a predetermined condition, the presentation order of the teaching materials is determined with reference to the relevance level table 120 shown in FIG. For example, in the condition that the learning material having the maximum relevance level Rij is presented, the learning material having the maximum relevance level Rij is searched from the row of the relevance level table Ii with respect to the learning material Ii given as the initial learning material. . For example, if the degree of association with the teaching material Ij is the maximum, the teaching material Ij is selected as the teaching material to be presented next. When there are a plurality of teaching materials having the maximum degree of relevance, an arbitrary one may be selected, or any one may be selected according to some second criterion (for example, sentence length).

  When the teaching material Ij is presented, the teaching material having the maximum relevance is searched from the row corresponding to the teaching material Ij in the relevance level table 120, and this is selected as the teaching material to be presented next.

  Further, instead of selecting a learning material having the maximum relevance level Rij, an arbitrary learning material may be selected from teaching materials having a higher relevance level than a preset threshold value.

  Also in this embodiment, the teaching material whose number of selections (the number of presentations) has reached n times may be set so that it is no longer selected as the next presenting teaching material. It is good also as a setting which is not selected as a presentation teaching material.

  The program flowchart for realizing the present embodiment is the same as that of the first embodiment except that in step 206 in FIG. Description is omitted.

  In the above-described embodiment, it is assumed that there is only one learner. However, as apparent from the fact that the above-described apparatus can be realized by a program, a plurality of programs are operated in parallel. It is also possible to give different series of problems to a plurality of learners using the same association degree table.

  The embodiment disclosed herein is merely an example, and the present invention is not limited to the above-described embodiment. The scope of the present invention is indicated by each claim in the claims after taking into account the description of the detailed description of the invention, and all modifications within the meaning and scope equivalent to the wording described therein are intended.
