Let me.

FIG. 2 is a diagram illustrating the classification and correlation of learning problems for one learning unit of mathematics.

In FIG. 2, Q1 to Q10 represent learning problems for one learning unit that are given in a predetermined number of times of learning in mathematics. In addition, classification information (classification ID) for classifying the learning problem by type is added to each learning problem. It means that learning problems to which the same classification information is added are related (relevant) to each other.

Each learning problem has a plurality of types (referred to as the first classification type) representing the learning field, such as the probability problem, the calculation problem, the geometric problem, and the graphic problem in FIG. 2, based on the entire content of the learning problem. It is classified as either. In the example of FIG. 2, Q2 belongs to the probability problem, Q1, Q5, Q6, and Q9 belong to the calculation problem, and Q4, Q8, and Q10 belong to the geometric problem. 3 and Q7 belong to the graphic problem.

In addition, each learning problem is classified into a type in which the type of the first classification is subdivided, or a type of knowledge required in the process of deriving the answer of the learning problem (referred to as the type of the second classification). In the example of FIG. 2, Q2 and Q6 belong to the differential calculation, and Q4, Q5, and Q10 belong to the matrix calculation. Depending on the learning problem, it does not belong to any of the second classification types.

The type of the first classification to which the learning problem belongs and the type of the second classification are added to each learning problem as classification information.

The number of classification information added depends on the learning problem. For example, with respect to Question 5 in FIG. 2, two classification informations, a calculation problem (calculation) which is a type of the first classification and a matrix calculation which is a type of the second classification, are added. For Question 1, one classification information of only the calculation problem (calculation), which is the type of the first classification, is added.

If any one of the classification information added to the learning problem matches any one of the classification information added to the other learning problem, those learning problems are related learning problems.

Further, in the example of FIG. 2, the case where the learning problem is classified by two classification methods of the first classification and the second classification has been described, but the learning problem may be classified by one or three or more classification methods.

In the storage unit 44, a subject ID representing a subject and classification information (classification ID) corresponding to each learning problem included in each learning unit are stored as problem classification.

FIG. 3 is a diagram illustrating the configuration of the learning screen 201 displayed on the display 102.

The user A may use the keyboard 85 or the mouse 84 of the input unit 42 when inputting the answer or the like in the answer area 242, or when the touch panel 83 is provided on the screen of the display 102, the user A may use the keyboard 85 or the mouse 84 of the input unit 42. Characters or the like may be directly written on the answer area 242 on the screen using a touch pen or the like.

The information input by the user in the answer area 242 is referred to as input information in the answer area 242.

The shared area 222 (screen) has a self area 261 and another person areas 262 to 264.

In the self-area 261, the input information to the answer area 242 of the self-terminal device 21 (the terminal device 21 used by the user A) is displayed. The user identification information 261A representing the user who is inputting the input information to the answer area 242 displayed in the self area 261 is displayed below the self area 261. As the user identification information 261A, "self", the user name of the user A, the user ID of the user A, and the like are displayed.

In the other area 262 to 264, the input information to the answer area 242 in the terminal device 21 of the shared user is displayed.

The shared user is a user (student) who is learning using a terminal device 21 different from the user A, and is a user other than the user A who is solving the same learning problem as the user A, and has a learning tendency. Refers to a user similar to user A. A user whose learning tendency is similar to that of user A represents a user who is grouped into a group having the same learning tendency as user A. The method of selecting shared users will be described later.

Below each other area 262 to 264, user identification information 262A to 264A of the user who is inputting the input information to the answer area 242 displayed in each other person area 262 to 264 is displayed. In FIG. 3, as the user identification information 262A to 264A, the user names of the user D, the user E, the user H, the user ID, and the like are displayed. User D, user E, and user H are examples of shared users who are solving the same learning problem as user A and are selected as users whose learning tendency is similar to that of user A.

In the following, the terminal device 21 used by a certain user is simply referred to as the terminal device 21 of that user. Further, the component (answer area 242, etc.) of the learning screen 201 displayed on the display 102 of the terminal device 21 of a certain user is simply referred to as the component of the user. For example, the answer area 242 of the learning screen 201 displayed on the display 102 of the terminal device 21 used by the user D is referred to as the answer area 242 of the user D.

Further, in FIG. 3, only the other areas 262 to 264 for three users exist in the shared area 222, but for example, by scrolling the screen in the shared area 222 or by displaying the screen in the shared area 222. By switching, the input information to the answer area 242 of three or more shared users may be displayed.

FIG. 4 is a diagram illustrating the detailed configuration of the shared area 222.

In FIG. 4, the shared area 222 shows the self area 261 shown in FIG. 3, the other areas 262 to 264, and the user identification information 261A to 264A.

In FIG. 4, a share button 265, a chat button 266, and a help button 267 are displayed at the upper part of the shared area 222. The share button 265, the chat button 266, and the help button 267 are buttons for switching the learning mode (operation mode of the terminal device 21) indicating the mode when the user solves the learning problem.

There are three learning modes: information sharing mode (shared mode, non-sharing mode), voice conversation mode (chat mode, non-chat mode), and help mode (help mode, non-help mode). It is determined by the combination of.

Further, as an operation mode of the terminal device 21, in addition to the learning mode in which the user learns, there is a teacher mode described later in which the learning user acts as a teacher and gives advice to other users.

The share button 265 is a graphical user interface that switches the learning mode (mode related to sharing) to the shared mode or the non-shared mode.

The sharing mode is a mode in which the input information to the user A (user A using the terminal device 21 displaying the information of the shared area 222 in FIG. 4) and the shared user's answer area 242 is shared. The non-shared mode is a mode in which the information is not shared.

The answer areas 242 of the user A and the shared user represent the answer area 242 on the learning screen 201 displayed on the display 102 of the terminal device 21 used by each user.

Each time user A clicks the share button 265 with a mouse or the like, the learning mode is switched between the shared mode and the non-shared mode. In the initial state, the learning mode is set to, for example, the shared mode. The operation of the graphical user interface on the screen such as the share button 265 is not limited to a specific method.

When the learning mode is set to the shared mode, communication is performed between the terminal device 21 of the user A and the terminal device 21 of the shared user in the shared mode.

The shared user in the shared mode means a shared user whose learning mode is set to the shared mode in the terminal device 21 of each shared user as in the case of user A.

Then, in the terminal device 21 of the user A, the input information to the answer area 242 of the user A is displayed in the self area 261, and the answer area 242 of the shared user in the shared mode is displayed in the other areas 262 to 264. The input information is displayed.

Further, in the terminal device 21 of each shared user in the shared mode, the input information to the answer area 242 of the user A is displayed in any of the other areas 262 to 264.

According to the sharing mode according to the present technology, the user A and the sharing user can input a question to another user, an answer to a question from another user, and the like by using each answer area 242. Further, since the user A and the shared user are users having similar learning tendencies, they can provide mutually useful information or teach, instead of providing one-sided information.

In addition, according to the sharing mode related to this technology, when there are many users (students) learning for the number of teachers, even if the teachers cannot respond appropriately to each student, the students can interact with each other. You will be able to give advice and explanations for learning problems.

Furthermore, according to the sharing mode related to this technology, students suitable for each student's learning level and comprehension level are selected as shared users, so that each student can perform efficient self-study.

The user selected as the shared user does not necessarily have to be a user who solves the same learning problem as user A, and does not necessarily have to be a user whose learning tendency is similar to that of user A.

When the learning mode is set to the non-shared mode, the input information for the shared user's answer area 242 is not displayed in the shared area 222, and the user A's answer is displayed in the shared area 222 of each shared user. The input information for the area 242 is also not displayed. The shared area 222 of each user represents the shared area 222 on the learning screen 201 displayed on the display 102 of the terminal device 21 used by each shared user.

The chat button 266 is a graphical user interface that switches the learning mode (mode related to voice conversation) to chat mode or non-chat mode.

The chat mode is a mode in which a voice conversation (voice conversation) is performed between the user A and another shared user, and the non-chat mode is a mode in which the voice conversation is not performed.

Each time user A clicks the chat button 266 with a mouse or the like, the learning mode is switched between chat mode and non-chat mode. In the initial state, the learning mode is set to, for example, a non-chat mode.

When the learning mode (mode related to information sharing) is set to the shared mode, the shared mode is maintained regardless of whether the learning mode (mode related to voice conversation) is set to the chat mode or the non-chat mode. Will be done. In this case, the learning screen 201 and the shared area 222 of the learning screen 201 are maintained in the states of FIGS. 3 and 4. Further, when the learning mode is set to the non-shared mode, the learning mode is automatically set to the non-chat mode, and the learning mode cannot be switched to the chat mode.

When the learning mode is set to chat mode, voice conversation between user A and the shared user is possible. However, the voice conversation between the user A and the shared user whose learning mode is set to the non-chat mode is not performed.

When the learning mode is set to the chat mode, the control unit 41 in the terminal device 21 of the user A receives the voice information from the microphone 81, and the terminal device 21 of the shared user whose learning mode is set to the chat mode. Is transmitted via the network unit 45.

Further, the network unit 45 of the terminal device 21 of the user A receives the voice information from the microphone 81 of the terminal device 21 of the shared user set in the chat mode and supplies the voice information to the control unit 41. The control unit 41 outputs the voice information from the network unit 45 from the speaker 101. In the terminal device 21 of the shared user whose learning mode is set to the chat mode, the same processing as that of the terminal device 21 of the user A is performed.

This enables voice conversation between user A and the shared user whose learning mode is set to chat mode.

When the learning mode is set to the non-chat mode, voice information is not transmitted / received between the terminal device 21 of the user A and the terminal device 21 of the shared user, and voice conversation is not performed.

The help button 267 is a graphical user interface that switches the learning mode (mode related to help) to the help mode or the non-help mode.

The help mode is a mode in which the user A asks for advice from another user (teacher user) who is a teacher different from the shared user, and the non-help mode is a mode in which the user A does not ask the teacher user for advice. The teacher user is a user selected from the users (students) who perform learning.

Each time user A clicks the help button 267 with the mouse or the like, the learning mode is switched between the help mode and the non-help mode. In the initial state, the learning mode is set to, for example, the non-help mode.

When the learning mode is set to the help mode, the transition to the help mode is transmitted from the terminal device 21 to the server device 22.

Upon receiving the transition from the terminal device 21 to the help mode, the server device 22 selects a teacher user and shifts the selected teacher user information (address of the terminal device 21 used by the teacher user, etc.) to the help mode. It is transmitted to the terminal device 21.

The teacher user is, for example, a user (student) who has already answered the learning problem answered by user A, and is a user who has correctly answered, and is not currently solving any learning problem (solving the learning problem). It is selected from users who have finished and before moving to the next learning problem, or who have finished solving the learning problem and have not finished learning). The method of selecting teacher users will be described later.

When the terminal device 21 of the user A receives the teacher user information from the server device 22, the terminal device 21 of the user A transmits a help communication connection request to the terminal device 21 of the teacher user based on the teacher user information. When the teacher user's terminal device 21 receives the help communication connection request from the user A's terminal device 21, a help button (described later) for the help request is displayed on the teacher user's learning screen 201. When the teacher user clicks the help button, the help request is accepted, and the terminal device 21 of the user A and the terminal device 21 of the teacher user are communicably connected.

FIG. 5 is a diagram illustrating the state of the shared area 222 in which the learning mode is set to the help mode.

When the learning mode is set to the help mode, in FIG. 5, in the other area 262 of one of the other areas 262 to 264 in the shared area 222, the answer area 242 of the teacher user (user X) is assigned to the answer area 242. The input information is displayed. User identification information 262A representing the user name and the like of the teacher user (user X) is displayed below the other area 262.

In addition, the input information for the answer area 242 of the user A is displayed in the self area 261. User identification information 261A representing "self", the user name of user A, and the like is displayed below the self area 261.

In this way, when the user A sets the learning mode to the help mode and the teacher user accepts the help request by the help button 281 of FIG. 6, the user A asks a question or the like to the teacher user in the same manner as the shared user. Can and get advice from teacher users.

Further, in FIG. 7, point information 295 is displayed at the upper part of the shared area 222. The point information 295 represents the number of points that the teacher user has acquired so far. By becoming a teacher user, each user can acquire a predetermined number of points each time, and the points are added to and accumulated in the past. When the accumulated teacher points exceed a certain number of points, the user is given the privilege of receiving a specific service and the privilege of being able to apply for a gift.

The number of points earned by the teacher user at one time is calculated when the user A or the like who requested the help switches the learning mode to the help mode or the non-help mode (the teacher user operates the terminal device 21). May be determined when switching to the teacher mode or when switching the operation mode to the non-teacher mode (learning mode).

As described above, the control unit 41 of the terminal device 21 of the user A of interest generates the learning screen 201 of FIG. 3 when the operation mode is set to the learning mode, and displays the learning screen 201 as image information on the display 102. The learning screen 201 is supplied and displayed on the display 102.

Further, when the user A is selected as the teacher user and receives a help request from the terminal device 21 of another user, the control unit 41 of the terminal device 21 of the user A includes learning including the help button 281 of FIG. The screen 201 is generated and displayed on the display 102.

Further, when the user A selected as the teacher user clicks the help button 281 of FIG. 6, the control unit 41 of the terminal device 21 of the user A switches the operation mode to the teacher mode. A learning screen 201 including the screen of the shared area 222 of FIG. 7 is generated and displayed on the display 102.

The control unit 41 generates a screen that simultaneously displays the screen of the question area 241 and the screen of the answer area 242 in the personal area 221 of the learning screen 201 of FIGS. 3 and 6 and the screen of the shared area 222 on the display 102. Then, the screen of the question area 241 and the screen of the answer area 242 and the screen of the shared area 222 are simultaneously displayed on the display 102.

However, when the user clicks a button (not shown), the control unit 41 switches the screen of the question area 241, the screen of the answer area 242, and the screen of the shared area 222 one by one and displays them on the display 102. May be good. Further, the control unit 41 may switch between two screens of the question area 241 screen, the answer area 242 screen, and the shared area 222 screen and the remaining one screen to be displayed on the display 102. ..

Further, the display form of the information input by the self and the shared user in the shared area 222 is not limited to the form shown in FIGS. 4, 5, 7, and the like. Further, the control unit 41 displays the information input in the answer area 242 in the shared area 222, but the information displayed in the shared area 222 may be the information input in an area other than the answer area 242. ..

(Collection of learning level information)
Next, the collection of learning level information of each user to be referred to when selecting a shared user will be described.

FIG. 8 is a diagram illustrating learning problems to be given to each user.

The learning problem 301 in FIG. 8 is a problem for finally finding the area on the graph.

The process of deriving the answer to the learning problem of FIG. 8 can be divided into 6 stages of answer phase 1 to answer phase 6 as follows.

Answer phase 1: Find the coordinates of points A and B.

Answer phase 2: Find the formula for the straight line AB.

Answer phase 3: Find the coordinates of point C.

Answer phase 4: Find the area of △ ACO.

Answer phase 5: Find the area of △ BCO.

Answer phase 6: Find the area of △ AOB.

In this way, each learning question is divided into a plurality of answer phases in advance, and the correctness of the user's answer is determined for each answer phase. It is assumed that there is only one answer phase for a learning problem that cannot be divided into a plurality of answer phases.

The storage unit 44 of the terminal device 21 used by each user stores a learning question created in advance, the content of the answering phase of each learning question, and the correct answer for each answering phase.

It is assumed that the control unit 41 of the terminal device 21 reads the learning problem from the storage unit 44, displays it in the problem area 241 of FIG. 3, and asks the user a question. At this time, the answer time analysis unit 62 of the control unit 41 resets the timer 46 and starts measuring the elapsed time after the learning question is displayed in the question area 241.

Further, the control unit 41 transmits information (learning problem information) about the question to be asked to the server device 22.

FIG. 9 is a diagram showing the format of the learning problem information.

In FIG. 9, the learning problem information includes problem ID, problem classification, and problem content information.

The question ID is an identification number that identifies each learning question, and a different identification number is assigned to each learning question in advance.

Problem classification consists of subject ID and classification ID (classification information). The subject ID is identification information that identifies the subject to which the learning problem belongs. The classification ID is identification information that identifies the classification information that classifies the learning problems described in FIG. 2 by type.

The question content is information that represents the content of the learning question.

FIG. 10 is a diagram showing a specific example of learning problem information.

In FIG. 10, the question ID is "0001", the question classification is "math: graph", and the question content is the learning question in FIG.

The control unit 41 transmits the learning problem information about the set learning problem to the server device 22 each time the learning problem is given to the user.

The user inputs the answer of the learning question displayed in the question area 241 into the answer area 242 of FIG. Then, for example, the user clicks an end button (not shown) to end the answer to the learning problem.

When the answer time analysis unit 62 of the control unit 41 finishes answering the learning question (when the user clicks the end button), the measurement time is acquired from the timer 46, and the learning question is given until the answer is finished. Find the answer time required to answer.

Further, the control unit 41 evaluates the answer when the answer to the user's learning problem is completed.

The answer analysis unit 63 of the control unit 41 analyzes the answers entered in the answer area 242 as the answer phase analysis, and detects the input points corresponding to each of the answer phases 1 to 6 and the input contents thereof.

The correct answer determination unit 61 of the control unit 41 determines the correctness of the content of the input portion corresponding to each answer phase input to the answer area 242 based on the correct answer of each answer phase of the learning question stored in the storage unit 44. judge.

Then, the correct answer determination unit 61 obtains the phase correct answer rate based on the correct / incorrect determination result. The phase correct answer rate represents the number of correct answer phases for the total number of answer phases.

When the above evaluation is completed for the answer of one learning problem, the control unit 41 transmits the answer information to the server device 22. The answer information includes the question ID of the learning question answered by the user, the answer time, and the phase correct answer rate (correctness of the answer).

When the server device 22 receives the answer information from the terminal device 21, the server device 22 adds the received answer information and the question classification information of the learning question information to the learning level information for each user stored in the storage unit 122. ..

FIG. 11 is a diagram illustrating the format of the learning level information.

In FIG. 11, the learning level information includes user ID, question classification, question ID, answer time, and phase correct answer rate information.

The user ID is identification information that identifies the user, and indicates that the learning level information is information about the user indicated by the user ID.

The question classification is the information included in the learning question information from the terminal device 21, and the answer time and the phase correct answer rate are the information included in the answer information from the terminal device 21.

Every time a user answers one learning question, one set of learning level information consisting of question classification, question ID, answering time, and phase correct answer rate is added to the learning level information about the user. Will be done.

FIG. 12 is a diagram showing a specific example of learning level information.

In FIG. 12, the user ID is "Mr. A", the question classification is "math: graph", the question ID is "0001", the answer time is "000512", and the phase correct answer rate is "04:06". Each is.

In the answer time "000512", the upper two digits represent hours, the following two digits represent minutes, and the lower two digits represent seconds. The force correct answer rate "04:06" represents n: N when the number of correct answer phases n and the number of all answer phases are N. A value of n / N can be adopted as the phase correct answer rate.

(How to select shared users)
Next, a method of selecting a shared user will be described.

To explain again focusing on a certain user A, the shared user selected for the user A is selected from the users who have the same learning problem as the user A and whose learning tendency is similar to that of the user A. Will be done. That is, the shared users selected for the user A are the users who are grouped into groups having the same learning tendency as the user A.

The problem solved by user A, that is, the learning problem given to user A in the problem area 241 of FIG. 3, is hereinafter referred to as a focus learning problem.

The user selected as the shared user is a user whose learning tendency regarding the attention learning problem is similar to that of user A.

That is, the user selected as the shared user is a user whose learning tendency regarding the learning problem whose problem classification matches the attention learning problem is similar to that of the user A.

The learning problem of interest and the learning problem whose problem classification matches are defined as follows.

Problem classification consists of subject (subject ID) and classification information (classification ID). A learning problem in which the subject and classification information completely match the focus learning problem is a learning problem in which the focus learning problem and the problem classification match.

In addition, as shown in FIG. 2, a plurality of types (plurality of classification information) may be added to the learning problem as classification information. In the example of FIG. 2, the types of the first classification and the types of the second classification are added to the learning problems of Q2, Q4, Q5, Q6, and Q10.

When a plurality of classification information is added to the focus learning problem, the learning problem in which the subjects match and one of the classification information added to the focus learning problem is added is the focus learning problem. And the problem classification is the same as the learning problem.

Note that a learning problem in which the focus learning problem and the problem classification match is called a related learning problem related to the focus learning problem.

Further, the fact that the learning tendency is similar to that of user A means that the tendency to answer and correct the answer to the related learning problem is similar to that of user A.

The tendency to answer related learning questions is related to the phase correct answer rate for related learning questions, the number of words and sentences worth adding points, and the answering time required for answering (details will be described later).

The tendency of correct answers to related learning questions is related to the degree of agreement between the related learning questions that answered correctly and the related learning questions that answered incorrectly (details will be described later).

The selection of the shared user for the user A is performed by the processing unit 121 of the server device 22 of FIG.

The correlation determination unit 141 in the processing unit 121 of FIG. 1 acquires learning problem information (see FIGS. 9 and 10) regarding the learning problem in which the terminal device 21 has started to give a question to the user A from the terminal device 21. Here, the learning problem that the terminal device 21 has started to ask the user A, that is, the learning problem that the user A is solving (the learning problem displayed in the problem area 241 of the user A) is set as the focus learning problem.

Then, the correlation determination unit 141 reads the learning level information (see FIGS. 11 and 12) stored in the storage unit 122 for the user who is solving the learning problem of interest (referred to as the user who is answering). As shown in FIG. 11, the learning level information includes the question classification of the learning question that the user has already answered during the answer, the answer time, and the phase correct answer rate.

The correlation determination unit 141 extracts the learning level information about the related learning problem (referred to as the related learning problem Q) among the learning problems that the user A has answered in the past, based on the learning level information of the user A.

Further, the correlation determination unit 141 extracts the learning level information of the related learning problem Q for the answering user other than the user A.

The correlation determination unit 141 extracts the learning level information for each answering user, for example, from the new learning level information to a predetermined number (for example, 30 etc.) of the learning level information, or from the past to the present. It may be limited to the range of learning level information added during the predetermined period up to.

The clustering unit 142 of the processing unit 121 of the server device 22 has a similar answer tendency to the user A based on the learning level information (answer information) of the related learning question Q for each answering user extracted by the correlation determination unit 141. The answering user to be answered and the answering user having a similar correct answer tendency to the user A are selected as shared candidate users who are candidates for the shared user.

The selection of shared candidate users whose answer tendency is similar to that of user A is based on the answer tendency classification by kNN (k-nearest neighbor algorithm: k-nearest neighbor method). On the other hand, the selection of shared candidate users whose correct answer tendency is similar to that of user A is performed based on the correct answer tendency analysis.

Then, the clustering unit 142 determines the shared user of the user A based on the shared candidate user having a similar answer tendency to the user A and the shared candidate user having a similar correct answer tendency to the user A.

(Selection of shared candidate users whose answer tendency is similar to that of user A: Answer tendency classification by kNN)
A method of selecting a shared candidate user whose answer tendency is similar to that of user A will be described.

The clustering unit 142 classifies the answer tendency by kNN one by one for the related learning question Q.

For example, assuming that the learning problem of FIG. 8 is one of the related learning problems Q, a case where the answer tendency classification by kNN is performed for the learning problem of FIG. 8 will be described.

13 and 14 are diagrams for explaining the answer tendency classification by kNN for the learning problem of FIG.

In the two-dimensional coordinates of FIGS. 13 and 14, the horizontal axis is the answer time and the vertical axis is the phase correct answer rate.

The clustering unit 142 obtains the coordinate points in the two-dimensional coordinates corresponding to the answer time and the phase correct answer rate of each user based on the learning level information of the learning problem of the user in FIG. 8 during each answer.

The two-dimensional coordinates in FIG. 13 show the coordinate points corresponding to the answer time and the phase correct answer rate of each answering user other than user A. For example, the shorter the answer time, the left the coordinate point on the two-dimensional coordinates, and the higher the phase correct answer rate, the higher the coordinate point on the two-dimensional coordinates.

FIG. 14 shows the two-dimensional coordinates in which the coordinate points corresponding to the answer time and the phase correct answer rate of the user A are added as points P1 or P2 with respect to the coordinate points of the two-dimensional coordinates of FIG. ..

Assuming that the coordinate point of the user A is the point P1 in FIG. 14, the clustering unit 142 uses kNN with k as 3, within the range of a circle having a radius r1 centered on the point P1, and 3 other than the point P1. Increase the radius r1 from 0 until only one coordinate point is included.

Then, when the three coordinate points a, b, and c other than the point P1 are included in the range of the circle as shown in FIG. 14, the clustering unit 142 sets the answer time for those coordinate points a, b, and c. And three answering users whose coordinate points correspond to the phase correct answer rate are selected as shared candidate users whose answering tendency is similar to that of user A.

That is, the three answering users corresponding to the coordinate points a, b, and c are users who are grouped into groups having the same answering tendency as the user A, and the three answering users are shared candidate users. Elected as.

Assuming that the coordinate point of the user A is the point P2 in FIG. 14, the clustering unit 142 uses a kNN with k as 3, within a circle having a radius r2 centered on the point P2, and has 3 other than the point P2. Increase the radius r2 from 0 until only one coordinate point is included.

Then, when the three coordinate points d, e, and f other than the point P2 are included in the range of the circle as shown in FIG. 14, the clustering unit 142 sets the answer time for those coordinate points d, e, and f. And three answering users whose coordinate points correspond to the phase correct answer rate are selected as shared candidate users whose answering tendency is similar to that of user A.

That is, the three answering users corresponding to the coordinate points d, e, and f are users who are grouped into groups having the same answering tendency as the user A, and the three answering users are shared candidate users. Elected as.

In this way, the clustering unit 142 uses kNN one by one for the related learning problem Q to share the user corresponding to the coordinate points included in the predetermined range centered on the coordinate point corresponding to the user A as a sharing candidate. Elected as a user.

The clustering unit 142 selected three users answering user A as shared candidate users having similar answering tendencies by kNN with k set to 3, but k was less than three or less than three. Four or more shared candidate users may be selected.

Further, the clustering unit 142 selects a user corresponding to the coordinate points included in the range of the circle centered on the coordinate point corresponding to the user A as a sharing candidate user, but within the range of the shape other than the circle (predetermined). A user corresponding to the coordinate points included in (within the range) may be selected as a sharing candidate user.

Further, the clustering unit 142 is a candidate for sharing the user corresponding to the coordinate points included in the range of the circle within the radius of the circle containing the predetermined number of coordinate points centered on the coordinate points corresponding to the user A. Although selected as a user, a user corresponding to a coordinate point included in a circle having a predetermined radius centered on the coordinate point corresponding to user A may be selected as a sharing candidate user. In addition, the shared candidate U-za may be selected only from the phase correct answer rate without considering the answer time.

According to the method of selecting a shared candidate user whose answer tendency is similar to that of user A, a user whose answer time is similar to that of user A is not simply a user who is similar to the correctness of the answer of user A as a shared candidate user. A user who is selected and whose tendency such as strengths and weaknesses in the academic field related to the learning problem of interest is similar to that of user A is selected as a shared candidate user.

(Selection of shared candidate users with similar correct answer tendency to user A: correct answer tendency analysis)
Next, a method of selecting a shared candidate user whose correct answer tendency is similar to that of user A will be described.

The clustering unit 142 selects users who are answering the related learning question Q with a similar tendency to correct answers.

The clustering unit 142 obtains the number of correct / incorrect matches of the related learning question Q of each answering user with respect to the correct / incorrect of the related learning question Q of the user A, and the user in the answer having a larger number of matches tends to have the correct answer with the user A. Sharing candidate users are preferentially selected in order from the answering user with the largest number of matches as being similar.

The case of analyzing the correct answer tendency from the learning questions for one learning unit of Q1 to Q10 shown in FIG. 2 will be described as an example.

Assuming that user A is answering question 10, question 10 is a learning problem of interest. Then, the related learning problem Q for Q10 is selected based on the problem classification of the attention learning problem and the learning level information (information of the problem classification) of the user A.

In Q1 to Q10 of FIG. 2, when Q10 is a focused learning problem, Q4 and Q8, which match the type of the first classification as a geometric problem with respect to Q10, correspond to the related learning problem Q. In addition, Q4 and Q5, which match the types of the second classification as matrix calculation with respect to Q10, correspond to the related learning problem Q.

Here, the correctness of question x, which is the related learning problem Q of question 10, which is the focus learning problem, is represented by qx (x is 1 to 9). For qx, 1 is for a correct answer and 0 is for an incorrect answer.

It is assumed that the user A correctly answers the learning questions of Q4 and Q5 with respect to Q4 and Q8 corresponding to the related learning question Q for Q10 as a geometric problem. At this time, (q4, q8) of user A is (1, 1).

On the other hand, assuming users B, C, D, and E as the answering users, user B's (q4, q8) is (1,1), user C's (q4, q5) is (0,0), and the user. It is assumed that (q4, q5) of D is (0,1) and (q4, q5) of user E is (1,0).

Regarding Q4 and Q8, the clustering unit 142 also obtains the number of correct / incorrect matches of each of users B to E for the correctness of user A with respect to the correctness of user A. As a result, the clustering unit 142 obtains the result that the number of matches of user B is 2, the number of matches of user C is 0, the number of matches of user D is 1, and the number of matches of user E is 1.

Similarly, as a matrix calculation, the clustering unit 142 also obtains the number of correct / incorrect matches of users B to E with respect to the correct / incorrect of user A for Q4 and Q5 corresponding to the related learning problem Q for Q10. User A's (q4, q5) is (1, 0), User B's (q4, q5) is (1, 1), User C's (q4, q5) is (0, 1), and User D's (q4). , Q5) is (0,0), and (q4, q5) of user E is (1,0). In this case, the clustering unit 142 obtains the result that the number of matches of user B is 1, the number of matches of user C is 0, the number of matches of user D is 1, and the number of matches of user E is 2.

The clustering unit 142 obtains the sum of the two matching numbers of each of these users B to E. As a result, the clustering unit 142 obtains the result that the number of matches of user B is 3, the number of matches of user C is 0, the number of matches of user D is 2, and the number of matches of user E is 3.

It should be noted that the clustering unit 142 does not obtain the number of correct / incorrect matches for the related learning problem Q in the learning problems for one learning unit, but the correctness of all the related learning problems Q extracted by the correlation determination unit 141. The number of matches may be calculated.

The larger the number of matches for user A's correctness, the higher the degree of similarity between user A and the correct answer tendency. For example, the clustering unit 142 selects users who are answering up to a predetermined order in descending order of the number of matches as shared candidate users who belong to the same group as user A in the correct answer tendency. However, the method of selecting as a shared candidate user who belongs to the same group as the user A in the correct answer tendency based on the number of matches is not limited to this.

According to the method of selecting shared candidate users whose correct answer tendency is similar to that of user A, the tendency of correctness of the answer to the learning problem is emphasized regardless of the answering time, and the user who is similar to user A is the shared candidate user. Be elected.

As described above, the clustering unit 142 has similar answer tendencies to user A (grouped into groups having the same answer tendencies as user A) and similar correct answer tendencies to user A (grouped into groups having the same answer tendencies). Select the shared candidate users (grouped into groups with the same correct answer tendency as user A).

When finding the number of matches for each of users B to E with respect to the correctness of user A, find the number of matches for each classification method (first classification and second classification) of the related learning problem Q, and classify them. Although the sum of the number of matches for each method was calculated, the number of matches may be calculated without dividing for each classification method.

When the sharing candidate users of the answer tendency and the correct answer tendency are selected as described above, the clustering unit 142 groups the shared candidate users into a group in which both the answer tendency and the correct answer tendency are the same as the user A. Determine as a shared user.

Here, in the clustering unit 142, users selected as having similar answer tendencies to any of the related learning questions Q for the learning problem of interest (users grouped into groups having the same answer tendencies as user A) are related. Find the number (number of selections) selected as having similar answer tendencies for all the questions in learning question Q.

Then, the clustering unit 142 may use users up to a predetermined number of users in descending order of the number of selections as sharing candidate users.

Further, in the clustering unit 142, when the number of shared candidate users grouped into a group in which both the answer tendency and the correct answer tendency are the same as the user A is large, the number of correct answers for the related learning question Q is the same. Users may be shared users up to a predetermined number of users in descending order or in descending order of the number of selections selected as having similar answer tendencies.

According to the above method for selecting a shared user, a user having a learning tendency similar to that of the user A is selected as the shared user. Therefore, the user A and the shared user, or the shared users can give advice and explanations to each other. Therefore, all users of user A and the shared user can perform efficient and meaningful learning.

The clustering unit 142 may select a shared user by using either a method of selecting a user having a similar answer tendency to the user A or a method of selecting a user having a similar correct answer tendency. .. That is, the clustering unit 142 may use users who are grouped into groups in which at least one of the answer tendency and the correct answer tendency is the same as the user A as a shared user.

(Selection of teacher users)
The teacher user is selected from among the users who have not answered the learning problem when the user A clicks the help button 267 in the shared area 222 of FIG.

In addition, the teacher user is selected from the users who have already answered the attention learning problem that the user A has answered.

When the processing unit 121 of the server device 22 receives from the terminal device 21 of the user A that the learning mode is set to the help mode, the processing unit 121 selects a user (referred to as a standby user) who has not answered the learning problem.

Subsequently, the processing unit 121 reads out the learning level information about the learning problem (focused learning problem) solved by the user A from the learning level information of FIG. 12 for each standby user.

Then, the processing unit 121 waits for the waiting user who has the shortest answer time and the highest phase correct answer rate based on the learning level information (answer information) read for each waiting user, or the waiting user who correctly answered the learning problem of interest. Election the user as a teacher user.

Note that the processing unit 121 may select the teacher user by using the same method as the answer tendency classification by kNN used for selecting the shared user. For example, the processing unit 121 obtains coordinate points corresponding to the answer time and the phase correct answer rate for the learning problem of interest of the waiting user in the two-dimensional coordinates in which the horizontal axis is the answer time and the vertical axis is the phase correct answer rate. Then, the user corresponding to the coordinate points distributed in the upper left on the two-dimensional coordinates is selected as the teacher user.

Note that the processing unit 121 may select a teacher user from other than the standby user who has not answered the learning problem when the user A clicks the help button 267.

In step S18, the control unit 41 sets the display of the shared area 222 on the learning screen 201 of FIGS. 3 and 4 to the non-shared mode display. That is, the control unit 41 does not display the information entered in the answer area 242 of the shared user in the shared area 222. The process proceeds from step S18 to step S24.

If it is determined in step S16 that the learning mode is the shared mode, the process proceeds to step S19.

In step S19, the control unit 41 connects the communication with the terminal device 21 of the shared user. The process proceeds from step S19 to step S20.

In step S20, the control unit 41 sets the display of the shared area 222 on the learning screen 201 of FIGS. 3 and 4 to the shared mode display. That is, the control unit 41 displays the information entered in the answer area 242 of the shared user in its own shared area 222 (other areas 262 to 264). The process proceeds from step S20 to step S21.

In step S21, the control unit 41 determines whether or not the learning mode is the chat mode.

If it is determined in step S21 that the mode is not in chat mode, the process proceeds to step S22, the control unit 41 blocks the voice information from the microphone 81, and does not send / receive the voice information to / from the terminal device 21 of the shared user. .. The process proceeds from step S22 to step S24.
