  Hereinafter, embodiments of a display program, a display device, and a display method according to the present invention will be described in detail with reference to the drawings.

(Embodiment)
FIG. 1 is an explanatory diagram of an example of the display method according to the embodiment. In FIG. 1, the display device 101 arranges and moves a plurality of symbols S in accordance with a symbol S placement instruction from each of a plurality of terminals T and a movement instruction for the symbol S for which the placement instruction is given. Is a computer that generates

  The symbol S is a symbol or a figure corresponding to each of the plurality of terminals T or the users of the plurality of terminals T. Each symbol S may include information specifying each terminal T or a user of each terminal T, for example, display of a terminal name of the terminal T, a user's name, and the like. The terminal T is a computer used by the user, and is, for example, a tablet PC, a smartphone, or a notebook PC.

  In each terminal T, the user can arrange the symbol S on a screen such as digital imitation paper or move the arranged symbol S. Digital imitation paper is electronic imitation paper (whiteboard) displayed on each terminal T, and is used for, for example, collaborative learning in school education or group discussion in a company.

  The user of each terminal T can express what he / she thinks depending on in which area on the digital imitation paper the symbol S is arranged or moved. The display device 101 may be realized by, for example, another computer that is communicably connected to a plurality of terminals T, or may be realized by each terminal T of the plurality of terminals T.

  Here, in collaborative learning, it is important to capture changes (changes) in the thinking of students. For example, the teacher can evaluate the thinking ability, judgment ability, etc. of the student by capturing the change in the thinking of the student. In addition, by sharing thought changes among students, it is possible to promote dialogue and develop the ability to revise one's thoughts.

  As a technique for capturing changes in the thinking of children and students, for example, there is a method of judging from a questionnaire before and after learning. However, with this method, it is difficult to capture changes in students' thinking in real time. In addition, it is possible to capture changes in thinking from the content of the students' remarks, but due to reasons such as class time and aggressiveness, some students who speak in the class become part of it and capture changes in the thinking of all students. It ’s difficult.

  Moreover, in collaborative learning, it is required to let students think about whether they disagree with or agree with the other's opinions, but there are places where they are opposed but sympathize. However, if it is difficult to understand how the opinions that you have spoken affect the other party, it may seem wasteful to speak, and in turn, you may instill a weak feeling of discussion. In addition, although the collaborative learning in school education was mentioned as an example and demonstrated here, it is not restricted to this. For example, a similar problem may occur in a conference or group discussion in a company.

  Therefore, in the present embodiment, a display method that makes it possible to capture changes in the user's thoughts by visualizing changes in the user's thoughts will be described. Hereinafter, a processing example of the display device 101 will be described.

  Here, a case will be described as an example in which whether or not a certain theme is in favor or not is discussed using a digital imitation paper screen displayed on the terminal T. The digital imitation paper screen is an operation screen on which the symbol S can be arranged or the arranged symbol S can be moved by an operation input by the user of the terminal T. However, the stronger the idea that the user agrees with a certain theme, the more the idea that the user places the symbol S on the left side of the digital imitation paper screen, and the stronger the opposite is, the more the symbol S appears on the right side of the digital imitation paper screen. Shall be placed.

  (1) The display device 101 instructs each of the plurality of terminals T to place a symbol S corresponding to each of the plurality of terminals T or the users of the plurality of terminals T, and a movement instruction about the symbol S for which the placement instruction has been made Accept. Then, the display device 101 generates image data for arranging and moving the plurality of symbols S in accordance with the placement instruction and the movement instruction.

  In the example of FIG. 1, image data 111 to 113 are generated according to the placement instruction and the movement instruction of the symbols S1 to S3 from the terminals T1 to T3. Symbols S1 to S3 are symbols S corresponding to users of the terminals T1 to T3, respectively. The image data 111 to 113 are image data of an operation screen (digital imitation paper screen) displayed in real time on each of the terminals T1 to T3 while performing collaborative learning.

  Thereby, in each terminal T1-T3, the change of each user's thought in collaborative learning etc. can be caught in real time by the change of the arrangement position of the symbol S. For this reason, for example, it becomes easy for the user to understand how the opinion he / she spoke affects the other party, and as a result, an effective discussion can be performed.

  (2) The display device 101 highlights the specific symbol S with respect to the other symbols S in response to receiving the movement history display instruction specifying the specific symbol S included in the plurality of symbols S. Screen data representing the movement history of each symbol S is generated. Here, highlighting a specific symbol S relative to other symbols S means displaying the specific symbols S in a display mode different from the other symbols S.

  Examples of highlighting include highlighting a specific symbol S, displaying it blinking, displaying it in a color different from that of other symbols S, and displaying it with higher saturation than other symbols S. It is done. As highlighting, a specific symbol S may be marked, or the specific symbol S may be surrounded by a frame.

  The movement history of each symbol S represents how the position of each symbol changes over time, and is represented by, for example, movement of an arrow and / or symbol S. The movement history display instruction is given, for example, during the collaborative learning or at an arbitrary timing after the collaborative learning.

  In the example of FIG. 1, screen data 121 to 123 are generated in response to a movement history display instruction designating the symbol S2. In the screen data 121 to 123, the symbol S2 is highlighted by displaying the symbol S2 in a color (●) different from the color (◯) of the symbols S1 and S3. In the screen data 121 to 123, the movement history of each symbol S1 to S3 is expressed by the movement of each symbol S1 to S3.

  Thereby, the change of the thought in the time series of each user in collaborative learning etc. can be confirmed at arbitrary timings. At this time, since the specified specific symbol S is highlighted, the user picks up the symbol S of a specific user, for example, a user who is worried about himself, or a user who is less active and difficult to judge a change in thinking. By highlighting, it is possible to capture changes in thought of a specific user over time.

(System configuration example of the learning support system 200)
Next, a system configuration example of the learning support system 200 according to the embodiment will be described. Here, a case where the learning support system 200 is used for collaborative learning performed in elementary and junior high schools will be described as an example.

In FIG. 2, the learning support system 200 is configured to include an information management device 201 and terminals T1 to Tn (n: a natural number of 2 or more). In the learning support system 200, the information management apparatus 201 and the terminals T1 to Tn are connected via a wired or wireless network 210. The network 210 is, for example, the Internet, a mobile communication network, a LAN (Local Area Network), a WAN (Wide Area Network), or the like.

  In the following description, an arbitrary terminal among the terminals T1 to Tn may be expressed as “terminal Ti” (i = 1, 2,..., N).

  Here, the information management apparatus 201 is a computer that has a user information DB (Database) 220 and an operation information DB 230 and manages the operation information of the terminals T1 to Tn. The operation information is information indicating an operation performed on the digital dummy paper screen EV in each terminal Ti. The digital imitation paper screen EV is an operation screen that can be shared between terminals, and can arrange symbols Si corresponding to each terminal Ti or a user of each terminal Ti, and can move the arranged symbols Si.

  The contents stored in the user information DB 220 and the operation information DB 230 will be described later with reference to FIGS. A screen example of the digital imitation paper screen EV will be described later with reference to FIGS. 8A, 8B, and 8C. The information management apparatus 201 may be a server or a PC, for example.

  The terminal Ti is a computer used by the user. The terminal Ti is, for example, a tablet PC, a smartphone, a notebook PC, or the like. The user is, for example, a child student or a teacher. The terminal Ti has an operation information table 240. However, since the data structure of the operation information table 240 is the same as that of the operation information DB 230, the illustration is omitted. The display device 101 illustrated in FIG. 1 corresponds to, for example, the terminal Ti.

  In the terminal Ti, the user can select, for example, a digital imitation paper mode and a movement history reproduction mode. The digital imitation paper mode is a mode in which a plurality of symbols S are arranged and moved in real time according to operation information (arrangement instruction, movement instruction, etc.) from each terminal T. For example, the digital imitation paper mode is selected when performing collaborative learning. Is done. The movement history reproduction mode is a mode in which the movement history of each symbol S is displayed in accordance with a movement history display instruction designating a specific symbol, and is selected, for example, during or after collaborative learning.

  In the present embodiment, the information management apparatus 201 is provided separately from the terminals T1 to Tn. However, the present invention is not limited to this. For example, the function of the information management apparatus 201 may be realized by any one of the terminals T1 to Tn.

  The terminal Ti may include, for example, various sensors, an SSD, a disk drive, a disk, a GPS (Global Positioning System) unit, and the like in addition to the components described above.

(Storage contents of user information DB 220)
Next, the contents stored in the user information DB 220 included in the information management apparatus 201 will be described. The user information DB 220 is realized by a storage device such as the memory 302 and the disk 305 of the information management apparatus 201 shown in FIG.

  FIG. 5 is an explanatory diagram showing an example of the contents stored in the user information DB 220. In FIG. 5, the user information DB 220 has fields of terminal ID, name, grade, class, and attendance number. By setting information in each field, user information (for example, user information 500-1, 500-2) is stored as a record.

  Here, the terminal ID is an identifier for uniquely identifying the terminal Ti. The name is the name of the user corresponding to the terminal Ti. The grade is the user's grade. The class is a user class. The attendance number is the attendance number of the user. When the user is a teacher, “-(Null)” is set as the attendance number.

(Storage contents of the operation information DB 230)
Next, the storage contents of the operation information DB 230 included in the information management apparatus 201 will be described. The operation information DB 230 is realized by a storage device such as the memory 302 and the disk 305 of the information management apparatus 201 shown in FIG.

  FIG. 6 is an explanatory diagram showing an example of the contents stored in the operation information DB 230. In FIG. 6, the operation information DB 230 includes fields for class ID, symbol ID, operation time, position, comment, and selected symbol ID. By setting information in each field, operation information (for example, operation information 600-1 to 600-3) is stored as a record.

  Here, the lesson ID is an identifier for uniquely identifying the lesson C in which the collaborative learning has been performed. As the class ID, for example, the name of class C can be used. The name of the lesson C is expressed by, for example, a combination of grade, class, subject, unit, and the like. The symbol ID is an identifier that uniquely identifies the symbol Si. The symbol ID of the symbol Si corresponding to the terminal Ti or the user of the terminal Ti is “Si”.

  The operation time indicates the date and time when the operation on the symbol Si was performed. The operation time may be, for example, the actual date and time when the operation on the symbol Si was performed at the terminal Ti, or the date and time when the information management apparatus 201 received the operation information from the terminal Ti (so-called time stamp). May be.

  The position indicates the position of the symbol Si on the digital dummy paper screen EV. Here, the position is expressed by coordinates in an orthogonal coordinate system including the X axis and the Y axis. The origin is set at an arbitrary position (for example, lower left) on the digital dummy paper screen EV. The comment indicates information input from the terminal Ti for the symbol Si. The selected symbol ID indicates the symbol ID of another symbol Sj (j ≠ i, j = 1, 2,..., N) selected immediately before moving the symbol Si.

(Functional configuration example of terminal Ti)
Next, a functional configuration example of the terminal Ti will be described.

  FIG. 7 is a block diagram illustrating a functional configuration example of the terminal Ti. In FIG. 7, the terminal Ti is configured to include a reception unit 701 and a display control unit 702. The reception unit 701 and the display control unit 702 are functions as control units. Specifically, for example, by causing the CPU 401 to execute a program stored in the memory 402 illustrated in FIG. 4 or by the I / F 403. Realize its function. The processing result of each functional unit is stored in the memory 402, for example.

  The accepting unit 701 accepts a display instruction for the digital imitation paper screen EV. As described above, the digital imitation paper screen EV is an operation screen on which the symbols Si corresponding to each terminal Ti or the user of each terminal Ti can be arranged or the arranged symbols Si can be moved.

  The display instruction of the digital imitation paper screen EV is performed, for example, when collaborative learning is started in the digital imitation paper mode. The display instruction of the digital imitation paper screen EV includes, for example, the class ID of class C in which collaborative learning is performed. Specifically, for example, the reception unit 701 receives a display instruction for the digital imitation paper screen EV by a user operation input using the input device 405 illustrated in FIG.

  The display control unit 702 performs control to display the digital dummy paper screen EV. Specifically, for example, when the display control unit 702 receives a display instruction for the digital imitation paper screen EV, the display control unit 702 displays the digital corresponding to the class ID included in the display instruction on the display 404 illustrated in FIG. The imitation paper screen EV is displayed.

  Note that the image data of the digital imitation paper screen EV corresponding to the class ID may be stored in the memory 402 in advance, for example. Further, the display control unit 702 may acquire image data of the digital imitation paper screen EV corresponding to the class ID from, for example, the information management apparatus 201 or another terminal Tj.

  A plurality of areas can be set on the digital imitation paper screen EV. The plurality of areas classify users having different opinions and assertions. For example, the user of the terminal Ti can express what he / she thinks depending on in which area on the digital dummy paper screen EV the symbol Si is arranged or moved.

  The setting of the area can be performed by each terminal Ti, for example, and the setting content is shared between the terminals. Two or more arbitrary areas can be set as the plurality of areas. In addition, in the digital imitation paper screen EV, which region of which shape is set can be performed by designating a boundary line between the regions, for example. Specifically, for example, the setting of the first area and the second area on the digital imitation paper screen EV is performed for each area adjacent to the boundary line according to the designation of the boundary line. The designation of the boundary line is performed by a user operation input using the input device 405, for example. However, the setting of the area may be permitted only at a specific terminal T (for example, a terminal T used by a teacher).

  The receiving unit 701 receives operation information indicating operations performed on the digital dummy paper screen EV. Examples of operations performed on the digital dummy paper screen EV include arrangement of symbols S, movement of symbols S, and input of comments. The arrangement of the symbol Si means that the symbol Si is arranged on the digital dummy paper screen EV. Further, the movement of the symbol Si means that the symbol Si arranged on the digital dummy paper screen EV is moved. That is, after the symbol Si is once arranged, the subsequent change in the position of the symbol Si is treated as the movement of the symbol Si.

  Specifically, for example, the accepting unit 701 accepts operation information indicating an operation performed on the digital imitation paper screen EV in its own terminal (terminal Ti) by a user operation input using the input device 405. In this case, the reception unit 701 transmits the received operation information to the information management apparatus 201. Further, the receiving unit 701 receives operation information from the information management apparatus 201, thereby receiving operation information indicating an operation performed on the digital dummy paper screen EV in another terminal Tj. However, the reception unit 701 may directly receive operation information from another terminal Tj.

  Note that when the operation information is received from the terminal Ti, the information management apparatus 201 stores the received operation information in the operation information DB 230. Then, the information management apparatus 201 transfers the operation information received from the terminal Ti to another terminal Tj. The other terminal Tj is a terminal of another user (child student or teacher) participating in the collaborative learning together with the user of the terminal Ti. For example, the information management apparatus 201 refers to the user information DB 220 illustrated in FIG. 5 as the other terminal Tj, and identifies a terminal of another user who has the same grade as the user of the terminal Ti and has the same class. You may decide. When starting collaborative learning, all users participating in collaborative learning may be registered in the information management apparatus 201.

  The operation information when the symbol S is arranged and moved includes, for example, a lesson ID, a symbol ID, an operation time, and a position. The class ID is an identifier that uniquely identifies class C in which collaborative learning has been performed. The symbol ID is an identifier that uniquely identifies the symbol S. The operation time indicates the date and time when the operation on the symbol S was performed. The position indicates the position of the symbol S arranged or moved on the digital dummy paper screen EV.

  The operation information when a comment is input further includes the input comment. When another symbol S is selected immediately before moving the symbol S, the operation information further includes a selected symbol ID indicating the symbol ID of the other symbol S. For example, the user of the terminal Ti selects the symbol Sj corresponding to the other user immediately before moving the symbol Si, when his / her idea changes greatly due to the influence of other users' opinions. The received operation information is stored in, for example, the operation information table 240 included in the terminal Ti.

  In the following description, the terminals T of a plurality of users (may include teachers) who participate in a certain collaborative learning may be referred to as “terminals T1 to Tn”.

  The display control unit 702 generates image data P that arranges and moves the symbols S <b> 1 to Sn based on the operation information received by the reception unit 701 and the operation information received from the information management apparatus 201. Each symbol S1 to Sn is a symbol or a figure representing the terminal T1 to Tn or the user of the terminal T1 to Tn. Each symbol S1 to Sn may include display of information (name, attendance number, etc.) specifying the user of each terminal T1 to Tn. Then, the display control unit 702 performs control to display the generated image data P.

  Note that information specifying the user of the terminal Ti may be stored in the memory 402 in advance, for example. Further, information specifying the user of the terminal Ti may be inquired from the terminal Ti to the information management apparatus 201. The information management apparatus 201 can specify the name, attendance number, and the like of the user of the terminal Ti with reference to the user information DB 220, for example.

  Specifically, for example, the display control unit 702 arranges the symbols S1 to Sn on the digital imitation paper screen EV or moves the arranged symbols S1 to Sn according to the received operation information. Data P is generated. Then, the display control unit 702 displays the generated image data P on the display 404.

  Thereby, according to the arrangement | positioning instruction | indication and movement instruction | indication of each symbol S1-Sn from each terminal T1-Tn, each symbol S1-Sn is arrange | positioned or arrange | positioned on the digital imitation paper screen EV displayed on the display 404. Each symbol S1 to Sn can be moved.

  In addition, for example, when the first region and the second region are set, the display control unit 702 calculates the number of symbols S belonging to the first region and the number of symbols S belonging to the second region. The image data P including the display may be generated. In the following description, the number of symbols S belonging to the first region may be expressed as “symbol number N1”. In addition, the number of symbols S belonging to the second region may be expressed as “symbol number N2”.

  The number of symbols N1 and N2 can be specified from the operation information table 240, for example. Specifically, for example, the display control unit 702 refers to the operation information table 240 and identifies the latest position of each symbol Si. Then, the display control unit 702 may calculate the number of symbols N1 and the number of symbols N2 based on the latest position of each identified symbol Si.

  However, the symbol numbers N1 and N2 may be inquired from the terminal Ti to the information management apparatus 201. In this case, the information management apparatus 201 refers to the operation information DB 230 and identifies the latest position of each symbol Si. Next, the information management apparatus 201 calculates the number of symbols N1 and the number of symbols N2 based on the latest position of each identified symbol Si. Then, the information management apparatus 201 transmits the calculated symbol numbers N1 and N2 to the terminal Ti.

  In addition, when the first region and the second region are set, the display control unit 702 determines whether the position of the arranged symbol S is included in the first region or the second region. You may decide to specify. Then, the display control unit 702 may set the color of the symbol S on the image data P according to the specified area. In this case, the display control unit 702 may maintain the set color of the symbol S until the display of the digital dummy paper screen EV is finished.

  Specifically, for example, when the position of the symbol Si arranged on the digital dummy paper screen EV is included in the first area, the display control unit 702 sets the color of the symbol Si to the first color. . On the other hand, when the position of the symbol Si is included in the second area, the display control unit 702 sets the color of the symbol Si to a second color different from the first color.

  Thereby, the color of the symbol Si can be determined according to the region where the symbol Si is first arranged. For this reason, even if the position of the symbol Si changes as collaborative learning progresses, it is possible to determine what idea the user corresponding to the symbol Si initially had.

  Also, the display control unit 702 determines whether the position of the moved symbol S is included in the first area or the second area when the first area and the second area are set. You may decide to specify. Then, the display control unit 702 may change the color of the symbol S on the image data P according to the specified area.

  Specifically, for example, when the position of the symbol Si moved on the digital dummy paper screen EV is included in the first area, the display control unit 702 changes the color of the symbol Si to the first color. . On the other hand, when the position of the moved symbol Si is included in the second region, the display control unit 702 changes the color of the symbol Si to a second color different from the first color.

  Thereby, whenever the area | region where symbol Si belongs with a movement, the color of symbol Si can be changed according to the area | region. For this reason, even if the boundary between the first region and the second region is not clearly shown, it is possible to intuitively determine to which region each symbol S belongs.

  Further, the display control unit 702 may perform control to display the boundary line designated when setting the first and second regions on the image data P. The boundary line is expressed by, for example, a solid line, a dotted line, a broken line, or the like. Accordingly, it is possible to easily determine the boundary between the first and second regions on the digital dummy paper screen EV.

  Further, the display control unit 702 may perform control to display information input from the terminal Ti corresponding to the symbol Si on the image data P together with the symbol Si. Specifically, for example, on the digital imitation paper screen EV, the reception unit 701 receives a display instruction for a comment corresponding to the symbol Si. The display control unit 702 identifies the comment corresponding to the symbol Si with reference to the operation information table 240 in response to the reception unit 701 receiving a display instruction for the comment corresponding to the symbol Si. Then, the display control unit 702 may display the specified comment in association with the symbol Si on the digital dummy paper screen EV.

  The accepting unit 701 accepts a movement history display instruction specifying a specific symbol S included in the symbols S1 to Sn. The movement history display instruction is given, for example, at any timing during or after cooperative learning in the movement history reproduction mode. The movement history display instruction includes, for example, a lesson ID and a symbol ID of a specific symbol S. Specifically, for example, the reception unit 701 receives a movement history display instruction in which a specific symbol S is specified by a user operation input using the input device 405.

  The display control unit 702 highlights the specific symbol S with respect to the other symbols S in response to the reception unit 701 receiving an instruction to display a movement history specifying the specific symbol S. Screen data Q representing the movement history is generated. Then, the display control unit 702 performs control to display the generated screen data Q.

  Specifically, for example, the display control unit 702 transmits an operation information acquisition request to the information management apparatus 201 in response to the reception unit 701 receiving a movement history display instruction. Here, the operation information acquisition request is for requesting operation information corresponding to the class ID included in the movement history display instruction. The operation information acquisition request includes the lesson ID included in the movement history display instruction.

  When receiving the operation information acquisition request from the terminal Ti, the information management apparatus 201 sequentially extracts operation information corresponding to the class ID included in the operation information acquisition request from the operation information DB 230 according to the operation time. And the information management apparatus 201 transmits the operation information extracted sequentially to the terminal Ti.

  As a result, in the terminal Ti, the operation information corresponding to the lesson ID included in the movement history display instruction is sequentially accepted according to the operation time. The display control unit 702 generates screen data Q each time operation information from the information management apparatus 201 is sequentially received. The operation information sequentially received from the information management apparatus 201 is stored in, for example, the operation information table 240.

  However, the operation information corresponding to the lesson ID included in the movement history display instruction may be stored in the operation information table 240. In this case, the display control unit 702 may generate the screen data Q by sequentially extracting the operation information corresponding to the lesson ID included in the movement history display instruction from the operation information table 240 according to the operation time. Good.

  More specifically, for example, the display control unit 702 highlights a specific symbol S relative to other symbols S on the movement history display screen MR based on operation information sequentially received from the information management apparatus 201. Screen data Q representing the movement history of each symbol S is generated. Then, the display control unit 702 displays the generated screen data Q on the display 404.

  Here, the movement history display screen MR is an operation screen representing the movement history of each symbol S. In the movement history display screen MR, the movement history of each symbol S is expressed by, for example, an arrow and / or movement of each symbol S. Note that expressing the movement history of the symbol S with an arrow means, for example, displaying an arrow connecting the symbols S before and after the movement. A screen example of the movement history display screen MR will be described later with reference to FIGS. 9A, 9B, 9C, 9D, and 9E.

  In addition, for example, when the first region and the second region are set, the display control unit 702 may generate the screen data Q including the display of the symbol number N1 and the symbol number N2. Further, the display control unit 702 may perform control to display the boundary line designated when setting the first and second areas on the screen data Q.

  In addition, when the first region and the second region are set, the display control unit 702 determines whether the position of the arranged symbol S is included in the first region or the second region. You may decide to specify. Then, the display control unit 702 may set the color of the symbol S on the screen data Q according to the specified area.

  Also, the display control unit 702 determines whether the position of the moved symbol S is included in the first area or the second area when the first area and the second area are set. You may decide to specify. Then, the display control unit 702 may change the color of the symbol S on the screen data Q according to the specified area.

  The display control unit 702 counts the number of times the symbol S has been moved based on the received operation information, and displays the counted number of movements on the screen data Q (or image data P). Also good. Specifically, for example, the display control unit 702 refers to the operation information table 240 and counts the number of times of movement of each symbol S1 to Sn (the number of operation information whose position is different from the previous position). Then, the display control unit 702 displays the counted number of movements of each of the symbols S1 to Sn on the screen data Q. Note that the display control unit 702 may count only the number of movements for the specified specific symbol S.

  When counting the number of movements of the symbol Si at a certain time t, the display control unit 702 refers to the operation information of the terminal Ti whose operation time is before the time t, and counts the number of movements of the symbol Si. However, the number of movements of the symbol Si at a certain time t may be inquired from the terminal Ti by specifying the class ID to the information management apparatus 201. In this case, the information management apparatus 201 moves the symbol Si with reference to the operation information of the terminal Ti whose operation time is earlier than the time t among the operation information corresponding to the designated class ID in the operation information DB 230. Count the number of moves.

  The display position for displaying the number of movements of the symbol S on the screen data Q can be arbitrarily set. Specifically, for example, the display control unit 702 may display the number of movements of the symbol S together with the symbol S on the movement history display screen MR. Further, the display control unit 702 may provide a display area for displaying the number of movements of each of the symbols S1 to Sn in the movement history display screen MR.

  Further, the display control unit 702 may perform control to display information input from the terminal Ti corresponding to the symbol Si on the screen data Q together with the symbol Si. Specifically, for example, on the movement history display screen MR, the accepting unit 701 accepts an instruction to display a comment corresponding to the symbol Si. The display control unit 702 identifies the comment corresponding to the symbol Si with reference to the operation information table 240 in response to the reception unit 701 receiving a display instruction for the comment corresponding to the symbol Si. Then, the display control unit 702 may display the specified comment in association with the symbol Si on the movement history display screen MR.

  Further, the symbol S on the image data P (digital imitation paper screen EV) has a user's idea (thinking) corresponding to the symbol S depending on the position in the axial direction parallel to the boundary line between the first area and the second area. ) May be expressed. In this case, the display control unit 702 may display a graph representing a time-series change in the position of the specific symbol S in the axial direction parallel to the boundary line. The graph is, for example, a line graph.

  For example, it is assumed that an area in the digital dummy paper screen EV is divided into a first area and a second area by a boundary line parallel to the Y axis. In this case, for example, the display control unit 702 refers to the operation information table 240 and identifies the time-series change in the Y coordinate of the specific symbol S. Next, the display control unit 702 generates a graph representing a time-series change in the Y coordinate of the specified specific symbol S. Then, the display control unit 702 displays the generated graph on the display 404. The graph generation instruction is performed, for example, on the movement history display screen MR.

  In addition, the display control unit 702 may display the specific symbol S on the screen data Q in a predetermined display mode when the movement distance by which the specific symbol S is moved is equal to or greater than the threshold value α. The threshold value α can be arbitrarily set. For example, when the moving distance is equal to or greater than the threshold value α, the threshold value α is set to a value that can be determined to have greatly changed the user's idea. As the predetermined display mode, for example, a specific symbol S is blinked and a specific symbol S is marked.

  In addition, the display control unit 702 counts the number of times the symbol S is selected immediately before moving another symbol S, and displays the counted number of selections on the screen data Q (or image data P). May be. Specifically, for example, the display control unit 702 refers to the selected symbol ID in the operation information table 240, and counts the number of times each of the symbols S1 to Sn is selected immediately before the other symbol S is moved. To do. For example, the number of selections of the symbol Si is the number of pieces of operation information in which “Si” is set as the selected symbol ID. Then, the display control unit 702 displays the counted number of selections of each of the symbols S1 to Sn on the screen data Q. Note that the display control unit 702 may count only the number of selections for the specified specific symbol S.

  When counting the number of selections of the symbol Si at a certain time t, the display control unit 702 refers to all the operation information whose operation time is before the time t, and counts the number of selections of the symbol Si. However, the number of selections of the symbol Si at a certain time t may be inquired from the terminal Ti by specifying the class ID to the information management apparatus 201. In this case, the information management apparatus 201 counts the number of selections of the symbol Si with reference to all the operation information whose operation time is before the time t among the operation information corresponding to the designated class ID in the operation information DB 230. To do.

  The display position for displaying the number of selections of the symbol S on the screen data Q can be arbitrarily set. Specifically, for example, the display control unit 702 may display the number of selections of the symbol S together with the symbol S on the movement history display screen MR. In addition, the display control unit 702 may provide a display area for displaying the number of selections of each of the symbols S1 to Sn in the movement history display screen MR.

  Further, when another symbol S is selected immediately before the specific symbol S is moved, the display control unit 702 indicates the correspondence relationship between the moved specific symbol S and the other symbol S selected immediately before. You may control to display on the screen data Q. Specifically, for example, the display control unit 702 may display a link (for example, a solid line, a dotted line, etc.) that connects a specific symbol S and another symbol S on the movement history display screen MR.

  Note that the display control unit 702 displays the specific symbol when the movement distance by which the specific symbol S is moved is equal to or greater than the threshold value α and another symbol S is selected immediately before the specific symbol S is moved. A link connecting S and another symbol S may be displayed. That is, a link between symbols may be displayed when a user's idea changes greatly due to the influence of other users' opinions.

(Screen example of digital imitation paper screen EV)
Next, a screen example of the digital imitation paper screen EV displayed on the display 404 of the terminal Ti will be described with reference to FIGS. 8A, 8B, and 8C.

  8A, 8B, and 8C are explanatory diagrams illustrating screen examples of the digital imitation paper screen EV. In (8-1), the digital imitation paper screen EV is an initial screen on which no symbol S is arranged. On the digital dummy paper screen EV, a first region TR1 and a second region TR2 are set, and a boundary line L between the first region TR1 and the second region TR2 is displayed.

  Here, an example will be described in which it is discussed whether to support “Takamori Saigo” or “Toshimichi Okubo” in collaborative learning.

  When each user supports “Takamori Saigo”, the user places a symbol S corresponding to each user in the first region TR1. At this time, each user places the symbol S on the left side in the first region TR1 as the desire to support “Takamori Saigo” increases. Each user arranges the symbol S on the upper side in the first region TR1 as the idea (thinking) that supports “Takamori Saigo” becomes clearer.

  On the other hand, when each user supports “Toshimichi Okubo”, the symbol S corresponding to each user is arranged in the second region TR2. At this time, each user arranges the symbol S on the right side in the second region TR2 as the desire to support “Toshimichi Okubo” increases. In addition, each user arranges the symbol S on the upper side in the second region TR2 as the idea (thinking) that becomes the basis for supporting “Toshimichi Okubo” is clearer.

  In (8-2), a plurality of symbols S are arranged on the digital imitation paper screen EV. The number displayed on each symbol S indicates the attendance number of the student corresponding to each symbol S. Here, the symbols S arranged in the first region TR1 and the symbols S arranged in the second region TR2 are set to different colors. The color of the symbol S set here is maintained until the display of the digital dummy paper screen EV is completed.

  Further, the number “13” of symbols S belonging to the first region TR1 is displayed in the display region Z1 in the digital dummy paper screen EV. In addition, the number “8” of symbols S belonging to the second region TR2 is displayed in the display region Z2. Thereby, it can be easily determined which of “Saigo Takamori” and “Okubo Toshimichi” is dominant. Here, when starting the discussion, Takamori Saigo is dominant.

  In (8-3) to (8-5), as the discussion proceeds, each symbol S moves. As a result, the number of symbols S belonging to the second region TR2 gradually increases, and in (8-5), the majority of students support “Toshimichi Okubo”. At this time, since the color set when the symbol S is arranged is maintained, by looking at the distribution of the color of each symbol S, many users who initially supported “Takamori Saigo” It can be intuitively judged that the idea has changed in favor of Toshimichi Okubo.

  In addition, although illustration is abbreviate | omitted, the comment about symbol Si is input or the comment input about each symbol S is displayed by selecting the symbol S on the digital imitation paper screen EV in terminal Ti. be able to.

(Screen example of the movement history display screen MR)
Next, screen examples of the movement history display screen MR displayed on the display 404 of the terminal Ti will be described with reference to FIGS. 9A, 9B, 9C, 9D, and 9E. Here, a screen example of the movement history display screen MR corresponding to the digital dummy paper screen EV shown in FIGS. 8A, 8B, and 8C will be described.

  9A, 9B, 9C, 9D, and 9E are explanatory diagrams illustrating screen examples of the movement history display screen MR. In (9-1), the movement history display screen MR is an initial screen. Similar to the digital imitation paper screen EV shown in (8-1), a first area TR1 and a second area TR2 are set on the movement history display screen MR, and the first area TR1 and the second area TR1 are displayed. A boundary line L with the second region TR2 is displayed.

  The movement history display screen MR includes a student list 910. In the student list 910, student names and check boxes (for example, check boxes 911) are displayed in association with each other. When any check box in the student list 910 is selected by a user operation input, a student symbol S corresponding to the selected check box is designated as a specific symbol S.

  Here, the check box 911 is selected, and the student's symbol S with the name “Fuji Hanako” is designated as the specific symbol S. However, the attendance number of the student with the name “Fuji Hanako” is “10”, and the symbol S is “symbol S10”. Then, when a reproduction button 920 in the movement history display screen MR is selected by a user operation input, display of the movement history of each symbol S is started.

  In the student list 910, two boxes (for example, boxes 912 and 913) are provided on the right side of each student's name. In the left box (for example, box 912), the number of times of movement of the symbol S is displayed. According to this number of movements, it is possible to grasp how many times the symbol S has been moved, that is, how many times the user's thought corresponding to the symbol S has changed. In the box on the right side (for example, box 913), the number of times the symbol S is selected immediately before the other symbol S is moved is displayed. According to the number of selections, it is possible to grasp the number of times other users have agreed to the opinion of the user corresponding to the symbol S. Note that the display content of each box is updated when, for example, the update button 930 is selected.

  In (9-2), a plurality of symbols S are arranged on the movement history display screen MR as in the digital imitation paper screen EV shown in (8-2). However, here, the symbol S10 designated as the specific symbol S is displayed in a frame and highlighted with respect to the other symbols S. Thus, the user can easily determine the symbol S10 designated as the specific symbol S.

  In the display area Z1 in the movement history display screen MR, the number “13” of symbols S belonging to the first area TR1 is displayed. In the display area Z2, the number “8” of symbols S belonging to the second area TR2 is displayed. Thereby, it can be easily determined which of “Saigo Takamori” and “Okubo Toshimichi” is dominant.

  In (9-3) to (9-5), each symbol S moves as time elapses. In (9-3), as a result of selecting the update button 930 by the user's operation input, the display contents of each box in the student list 910 are updated. For example, “5” is displayed in the box 912 and “1” is displayed in the box 913. Thereby, the user can recognize the number of movements “5” and the number of selections “1” of the symbol S10 at this time.

  In (9-4), as a result of the movement distance of moving the symbol S10 being equal to or greater than the threshold value α, the arrow AR connecting the symbols S10 before and after the movement is displayed, and the symbol S10 after the movement is blinked. ing. In addition, since another symbol S5 is selected immediately before the symbol S10 is moved, a link K that connects the symbol S10 and the other symbol S5 is displayed.

  This makes it difficult to overlook the moment when the user's thought (thinking) corresponding to the symbol S10 has changed significantly. In addition, it is possible to understand who has moved the symbol S10, that is, who has changed the idea greatly. The blinking display of the symbol S10 is performed, for example, until a certain time (for example, several seconds) elapses or is canceled by a user operation input.

  In (9-5), as a result of selecting the update button 930 by the user's operation input, the display content of each box in the student list 910 is updated. For example, “0 (0)” is displayed in the box 914 of the student with the name “Saburo Takahashi”, and “5” is displayed in the box 915. However, the attendance number of the student with the name “Saburo Takahashi” is “No. 5” and the symbol S is “Symbol S5”. The number in parentheses in the box 914 is the number of movements at the time of the previous update.

  As a result, the user refers to the box 915 to determine that there are many (5) who agree with the opinion of the student of the name “Saburo Takahashi” and that the opinion of this student has a great influence on the whole. Can do. In addition, the number of times of movement of the symbol S is displayed in the left box (for example, boxes 912 and 914) corresponding to each student. Also, the number of movements from a certain point in time (for example, the timing set by the teacher during the lesson, the timing of pressing the update, etc.) is displayed in parentheses following the number of movements. As a result, it is possible to easily grasp the symbol S (student's opinion) that has been moved after the previous confirmation that the teacher confirmed the number of movements. For this reason, from among many symbols S, the moved symbol S and the unmoved symbol S are grasped. For example, if there is a movement in the symbol S of the student who does not speak in the class, the opinion ( It is possible to grasp the moment when the transformation is happening and to develop lessons that could not be done so far, such as encouraging remarks.

  On the movement history display screen MR, when any symbol S is selected by a user operation input, a menu screen (not shown) is displayed. On the menu screen, items such as comment display, graph generation, and number of approvals can be selected. For example, when the number of approval items is selected on the menu screen of the symbol S5, the number of times (selection frequency) that another user has agreed to the opinion of the user corresponding to the symbol S5 can be displayed. At this time, for example, the terminal Ti may list other users who have selected the symbol S5 at the position shown in FIG. 9D and display them in a selectable manner. Note that the other user who has selected the symbol S5 at the position shown in FIG. 9D is, for example, operation information after moving the symbol S5 to the position shown in FIG. 9D, and “S5” is set as the selected symbol ID. Can be identified from the operation information. Then, the terminal Ti stores the movement history of the selected user's symbol S, for example, the movement history of other users' symbols S before and after selecting the symbol S5 (including arrows connecting the symbols S before and after the selection). Display may be possible. At this time, the terminal Ti may display information indicating the length (distance) of the arrows connecting the symbols S before and after the selection. As a result, the user corresponding to the symbol S5 can visually grasp how much his / her speech has affected the other party from the movement number and movement history (distance) of the other user's symbol S. , Can improve the willingness to participate in discussions and devise (improvement) the remarks.

  In the example (9-5), as a result of selecting the comment display item on the menu screen of the symbol S5, the comment 940 input from the terminal T5 is displayed in association with the symbol S5. Thereby, the user can confirm the comment 940 input by the student who has had a great influence on the whole.

  Also, on the movement history display screen MR shown in (9-5), for example, when a graph generation item is selected on the menu screen of the symbol S2, a graph 1010 as shown in FIG.

  FIG. 10 is an explanatory diagram illustrating a specific example of a graph. In FIG. 10, a graph 1010 is displayed on the graph screen 1000. A graph 1010 is a line graph showing a time-series change in the clarity of the idea of the user (attendance number: 2; name: Jiro Inada) of the symbol S2.

  According to the graph 1010, it is possible to grasp how the clarity of thought of the user (attendance number: No. 2, name: Jiro Inada) has changed over time. Specifically, according to the graph 1010, it can be seen that the clarity of the idea of the user (attendance number: No. 2, name: Jiro Inada) increases with time. In this way, by making it possible to visually grasp the clarity of thoughts of students in the course development, it is possible to confirm the degree of understanding of the students, and to improve individual guidance and class development. Can be connected. Further, the terminal Ti may display a screen in which, for example, the graph 1010 and the movement history display screen MR (for example, FIGS. 9A to 9E) are overlapped. Thereby, it is possible to make it easy to grasp not only the temporal change in the clarity of the thoughts of the students but also the thoughts of the students at that time. In this way, by making it possible to grasp and grasp the change history of the thoughts and understandings of the students, it can be used for confirming the achievement and understanding of the lesson goals of the students.

(Display processing procedure of terminal Ti in digital imitation paper mode)
Next, a display processing procedure of the terminal Ti in the digital imitation paper mode will be described.

  FIG. 11 is a flowchart illustrating an example of a display processing procedure of the terminal Ti in the digital imitation paper mode. In the flowchart of FIG. 11, first, the terminal Ti determines whether or not a display instruction for the digital imitation paper screen EV has been received (step S1101). Here, the terminal Ti waits to receive a display instruction for the digital imitation paper screen EV (step S1101: No).

  If the display instruction for the digital imitation paper screen EV is received (step S1101: Yes), the terminal Ti displays the digital imitation paper screen EV corresponding to the class ID included in the display instruction on the display 404 (step S1102). ). Here, it is assumed that the first area and the second area in the digital imitation paper screen EV are set.

  Next, the terminal Ti determines whether or not the operation information has been accepted by a user operation input using the input device 405 or by receiving operation information from the information management device 201 (step S1103). Here, when the operation information is not received (step S1103: No), the terminal Ti moves to step S1109.

  On the other hand, when the operation information is received (step S1103: Yes), the terminal Ti stores the received operation information in the operation information table 240 (step S1104). Next, the terminal Ti refers to the operation information table 240 and determines whether there is other operation information having the same symbol ID as the received operation information (step S1105).

  Here, when there is no other operation information (step S1105: No), the terminal Ti arranges the symbol S on the digital dummy paper screen EV based on the received operation information (step S1106). At this time, the terminal Ti specifies whether the position of the arranged symbol S is included in the first area or the second area, and sets the color of the symbol S according to the specified area. It may be.

  Next, the terminal Ti refers to the operation information table 240 and calculates the symbol numbers N1 and N2 of the first and second regions (step S1107). The terminal Ti displays the calculated symbol numbers N1 and N2 on the digital dummy paper screen EV (step S1108). Next, the terminal Ti determines whether or not the display of the digital imitation paper screen EV has ended (step S1109).

  Here, when the display of the digital imitation paper screen EV has not ended (step S1109: No), the terminal Ti returns to step S1103. If there is other operation information in step S1105 (step S1105: Yes), the terminal Ti determines whether or not the received operation information and the other operation information have the same position (step S1110). .

  If the positions are the same (step S1110: YES), the terminal Ti moves to step S1109. On the other hand, if the positions are different (step S1110: No), the terminal Ti moves the symbol S on the digital dummy paper screen EV based on the received operation information (step S1111), and proceeds to step S1107.

  In step S1109, when the display of the digital imitation paper screen EV is completed (step S1109: Yes), the terminal Ti ends the series of processes according to this flowchart. Thereby, according to the arrangement | positioning instruction | indication and movement instruction | indication of each symbol S1-Sn from each of terminal T1-Tn, the image data P which arrange | positions and moves symbol S1-Sn can be produced | generated and displayed on the display 404.

  The stored contents of the operation information table 240 may be initialized at the start or end of the lesson C (collaborative learning), for example.

(Transfer processing procedure of information management apparatus 201 in digital imitation paper mode)
Next, a transfer processing procedure of the information management apparatus 201 in the digital imitation paper mode will be described.

  FIG. 12 is a flowchart illustrating an example of a transfer processing procedure of the information management apparatus 201 in the digital imitation paper mode. In the flowchart of FIG. 12, first, the information management apparatus 201 determines whether operation information has been received from the terminal Ti (step S1201). Here, the information management apparatus 201 waits to receive operation information from the terminal Ti (step S1201: No).

  When the operation information is received from the terminal Ti (step S1201: Yes), the information management apparatus 201 stores the received operation information in the operation information DB 230 (step S1202). Next, the information management apparatus 201 transfers the received operation information to another terminal Tj (step S1203), and ends a series of processes according to this flowchart.

  Thereby, the operation information from the terminal Ti can be transferred to the terminal Tj of another user participating in the collaborative learning.

(Display processing procedure of terminal Ti in movement history reproduction mode)
Next, a display processing procedure of the terminal Ti in the movement history reproduction mode will be described.

  13 and 14 are flowcharts showing an example of a display processing procedure of the terminal Ti in the movement history reproduction mode. In the flowchart of FIG. 13, first, the terminal Ti determines whether or not an instruction to display a movement history specifying a specific symbol S has been received (step S1301). Here, the terminal Ti waits to receive a movement history display instruction (step S1301: No).

  If a movement history display instruction is received (step S1301: Yes), the terminal Ti displays a movement history display screen MR corresponding to the class ID included in the display instruction on the display 404 (step S1302). Here, it is assumed that the first area and the second area in the movement history display screen MR are set.

  Note that the image data of the movement history display screen MR (initial screen) corresponding to the class ID may be stored in the memory 402 in advance, for example. Further, the terminal Ti may acquire the image data of the movement history display screen MR corresponding to the class ID from, for example, the information management apparatus 201 or another terminal Tj.

  Next, the terminal Ti transmits an operation information acquisition request to the information management apparatus 201 (step S1303). The operation information acquisition request includes the lesson ID included in the received movement history display instruction. Then, the terminal Ti receives the operation information from the information management apparatus 201, and determines whether or not the operation information has been received (step S1304).

  Here, when the operation information is received (step S1304: Yes), the terminal Ti stores the received operation information in the operation information table 240 (step S1305). Next, the terminal Ti refers to the operation information table 240 and determines whether there is other operation information having the same symbol ID as the received operation information (step S1306).

  Here, when there is no other operation information (step S1306: No), the terminal Ti determines whether or not the symbol ID included in the received operation information matches the symbol ID of the specified specific symbol S. (Step S1307). Here, when the symbol ID matches the symbol ID of the specific symbol S (step S1307: Yes), the terminal Ti places the symbol S highlighted on the movement history display screen MR with respect to the other symbols S ( Step S1308) and the process proceeds to Step S1401 shown in FIG.

  On the other hand, if it does not match the symbol ID of the specific symbol S (step S1307: No), the terminal Ti places the symbol S on the movement history display screen MR (step S1309), and proceeds to step S1401 shown in FIG. . In step S1308 and step S1309, the terminal Ti specifies whether the position of the arranged symbol S is included in the first area or the second area, and the symbol S is determined according to the specified area. The color may be set.

  If there is other operation information in step S1306 (step S1306: Yes), the terminal Ti determines whether or not the received operation information and the other operation information are in the same position (step S1310). . If the positions are the same (step S1310: YES), the terminal Ti moves to step S1401 shown in FIG.

  On the other hand, if the positions are different (step S1310: No), the terminal Ti moves the symbol S on the movement history display screen MR based on the received operation information (step S1311), and proceeds to step S1401 shown in FIG. Transition. In step S1304, when the operation information is not received (step S1304: No), the terminal Ti moves to step S1403 shown in FIG.

  In the flowchart shown in FIG. 14, first, the terminal Ti refers to the operation information table 240 and calculates the numbers of symbols N1 and N2 in the first and second regions (step S1401). The terminal Ti displays the calculated symbol numbers N1 and N2 on the movement history display screen MR (step S1402).

  Next, the terminal Ti determines whether or not an update button 930 (see, for example, FIG. 9A) is pressed on the movement history display screen MR (step S1403). If the update button 930 has not been pressed (step S1403: No), the terminal Ti moves to step S1406.

  On the other hand, when the update button 930 is pressed (step S1403: Yes), the terminal Ti refers to the operation information table 240 and counts the number of movements of each symbol S (step S1404). The terminal Ti displays the counted number of times of movement of each symbol S on the movement history display screen MR (step S1405).

  Next, the terminal Ti determines whether or not the display of the movement history display screen MR is finished (step S1406). Here, when the display of the movement history display screen MR has not ended (step S1406: No), the terminal Ti returns to step S1304 shown in FIG. On the other hand, when the display of the movement history display screen MR is ended (step S1406: Yes), the terminal Ti ends a series of processes according to this flowchart.

  As a result, the specific symbol S included in the symbols S1 to Sn can be highlighted with respect to the other symbols S, and the movement history of each symbol S1 to Sn can be displayed.

(Transfer processing procedure of the information management apparatus 201 in the movement history reproduction mode)
Next, a transfer processing procedure of the information management apparatus 201 in the movement history reproduction mode will be described.

  FIG. 15 is a flowchart illustrating an example of a transfer processing procedure of the information management apparatus 201 in the movement history reproduction mode. In the flowchart of FIG. 15, the information management apparatus 201 first determines whether or not an operation information acquisition request has been received from the terminal Ti (step S1501). Here, the information management apparatus 201 waits to receive an operation information acquisition request from the terminal Ti (step S1501: No).

  When the information management apparatus 201 receives the operation information acquisition request (step S1501: Yes), the information management apparatus 201 extracts from the operation information DB 230 unextracted operation information corresponding to the class ID included in the received operation information acquisition request. The operation information is extracted according to the operation time (step S1502).

  Next, the information management apparatus 201 transmits the extracted operation information to the terminal Ti (step S1503). Then, the information management apparatus 201 determines whether there is unextracted operation information that has not been extracted among the operation information corresponding to the class ID included in the operation information acquisition request (step S1504).

  If there is unextracted operation information (step S1504: YES), the terminal Ti returns to step S1502. On the other hand, when there is no unextracted operation information (step S1504: No), the information management apparatus 201 ends a series of processes according to this flowchart.

  Thereby, according to the operation information acquisition request from the terminal Ti, the operation information corresponding to the class ID included in the operation information acquisition request can be sequentially transferred according to the operation time.

  As described above, according to the terminal Ti according to the embodiment, the arrangement instruction (operation information) of the symbol S corresponding to each of the terminal T or the user of the terminal T, and the arrangement instruction from each of the plurality of terminals T. It is possible to accept a movement instruction (operation information) for the symbol S that has been made. Then, according to the terminal Ti, it is possible to generate image data P (digital imitation paper screen EV) for arranging and moving a plurality of symbols S according to the received arrangement instruction and movement instruction.

  Thereby, in terminal Ti, by confirming the position and movement of each symbol S on the digital imitation paper screen EV, it is possible to capture changes in the thinking of each user participating in collaborative learning in real time. This makes it easier for students to understand how the opinions they have spoken affect the other party, and as a result, it is possible to conduct effective discussions. In addition, teachers can evaluate thinking ability, judgment ability, etc. even for students who have not spoken in class by capturing changes in thinking.

  In addition, according to the terminal Ti, it is possible to accept a movement history display instruction specifying a specific symbol S included in a plurality of symbols S. According to the terminal Ti, in response to receiving the movement history display instruction, the screen data Q expressing the movement history of each symbol S by highlighting the specific symbol S with respect to the other symbols S is displayed. Can be generated.

  Thereby, the user (for example, teacher) can confirm the change of the thought in the time series of each student in collaborative learning at arbitrary timings. At this time, since the specified specific symbol S is highlighted, it is possible to pick up students and the like that are less active and difficult to judge a change in thinking from a statement, and to capture a change in thinking in time series.

  Further, according to the terminal Ti, when the first region and the second region are set, the number of symbols S belonging to the first region and the number of symbols S belonging to the second region are displayed. The image data P (digital imitation paper screen EV) or the screen data Q (movement history display screen MR) can be generated. Accordingly, the user can intuitively determine whether the opinion or claim corresponding to any of the first and second regions is dominant or inferior.

  Further, according to the terminal Ti, the first region and the second region can be set for each region adjacent to the boundary line according to the designation of the boundary line (L). Thereby, a plurality of areas for classifying users having different opinions and assertions can be set by a simple operation of designating a boundary line on the digital imitation paper screen EV.

  Further, according to the terminal Ti, when the first area and the second area are set, it is determined which of the first area and the second area the position of the arranged symbol S is included. The color of the symbol S on the image data P or the screen data Q can be set according to the specified area.

  Thereby, the color of the symbol S can be determined according to the area | region where the symbol S was arrange | positioned initially. For this reason, even if the position of the symbol S changes as the collaborative learning progresses, it is possible to determine from the color of the symbol S what idea the user corresponding to the symbol S initially had. it can.

  Further, according to the terminal Ti, when the first area and the second area are set, it is determined which of the first area and the second area the position of the moved symbol S is included. The color of the symbol S on the image data P or the screen data Q can be changed according to the specified area.

  Thereby, whenever the area | region where the symbol S changes with a movement, the color of the symbol S can be changed according to the area | region each time. For this reason, even if the boundary between the first region and the second region is not clearly shown, it is possible to intuitively determine to which region each symbol S belongs. For example, when the first area and the second area are set, the terminal Ti can further divide each area further and color-code the background. That is, a color boundary line may be provided. Specifically, for example, the terminal Ti sets a boundary line of a color that divides each area into K segments (K: a natural number of 2 or more) parallel to the boundary line between the first area and the second area. May be. This allows, for example, not only to divide opinions by white (in favor) and black (opposite) at the boundary line on the digital imitation paper screen EV, but also to visually understand the situation of opinions including intermediate opinions. It can make it easy to grasp. Moreover, it is possible to focus on intermediate opinions and facilitate the development of discussions.

  Further, according to the terminal Ti, the number of times of movement of the symbol S can be counted based on the received operation information, and the counted number of movements can be displayed on the screen data Q. Thereby, the user can easily determine how many times the thoughts (thoughts) of the students have changed in the class.

  Further, according to the terminal Ti, the change history of the user can be easily grasped intuitively by expressing the movement history of the symbol S by the movement of the arrow and / or the symbol S.

  Further, according to the terminal Ti, information (comments) input from the terminal T corresponding to the symbol S can be displayed on the image data P or the screen data Q together with the symbol S. Thereby, each user can judge the validity of the opinion and claim of the student while confirming the comment etc. input by the student.

  Further, according to the terminal Ti, it is possible to display a graph representing a time-series change in the position of the specific symbol S in the axial direction parallel to the boundary line between the first region and the second region. Thereby, the time series change of the clearness degree of the user's idea corresponding to the specific symbol S can be visualized. For this reason, the teacher can confirm how the user's idea has changed as the class progresses, and can evaluate the user's understanding and thinking ability.

  Further, according to the terminal Ti, when the distance that the specific symbol S is moved is equal to or greater than the threshold value α, the specific symbol S can be displayed in a predetermined display mode (for example, blinking display). Thereby, it is possible to make it difficult to overlook the moment when the user's thinking corresponding to the specific symbol S changes greatly.

  For these reasons, according to the learning support system 200 according to the embodiment, it is possible to support the fulfillment of collaborative learning by the students and the evaluation of the students by the teacher. Can develop abilities, judgment, understanding, etc. For example, according to the learning support system 200, a choice such as a questionnaire or a clicker that expresses one of the choices such as white (in favor) / black (opposite), 3 choices, and 5 choices (total value Z1, In addition to Z2), there are not only two choices such as white and black, but also an intermediate (gray) opinion (think) that is neither white nor black, or a slightly white (light gray) opinion (think) Can be expressed by the display position of the symbol S. A change in opinion (thinking) can be displayed by a change in the display position of the symbol S. Thereby, the change of the situation of the opinion (thinking) of black and white can be grasped visually. Further, the degree of white / black can be grasped by the position of the symbol S. Furthermore, by visually grasping the doubt of the opinion (thinking) of white or black, it is possible to grasp the tendency of thinking of students (thought change), and to use the information for guidance and evaluation by the teacher. Can do.
