Description

  The present invention relates to a display control program, a display control device, and a display control method.

  In recent years, demonstration experiments of next-generation education using information terminals including tablet terminals have been conducted, and it is thought that this next-generation education will spread nationwide in the future.

  As a form of next-generation education using information terminals, teachers present students with assignments, and students input their opinions on tablet terminals, etc. An example of this would be to have students present their opinions and discuss them as a whole.

  In this form, for example, an assignment is transmitted from a teacher terminal held by a teacher to a student terminal held by each student. In each student terminal, an answer column is displayed on the display, and each student inputs an opinion in the answer column. At the student terminal for which input has been completed, the student's answer (opinion) is transmitted (submitted) and received by the teacher terminal, and displayed in a list, for example, in a matrix on the teacher terminal or the electronic blackboard.

Japanese Patent Laid-Open No. 08-263251 JP 2012-53824 A

  In the form of the above-mentioned class, it is preferable to display the opinions of all students on the electronic blackboard or the like so as to proceed with the discussion. However, for example, when displaying the opinions of all students in a class of 40 students, In the case of an electronic blackboard of a size that can be installed in a classroom, the display size of the opinion per student is small, so the letters are small. In this case, it is difficult for students in the seat away from the electronic blackboard (for example, behind the classroom) to view the opinion displayed on the electronic blackboard.

  For this reason, for example, the teacher selects a certain opinion from among the opinions displayed in a matrix form, and the opinions of some students (for example, nine students) including the selected opinion are enlarged and displayed on the electronic blackboard (highlighted) ) The style of the lesson is also conceivable. In this case, the teacher can proceed with the discussion while moving the enlarged display area (enlarged area) in the list screen. This makes it easier for students in the seat away from the electronic blackboard to view the enlarged view on the electronic blackboard, so that the student can be expected to actively participate in the discussion.

  However, in a class where discussions can proceed while moving the enlarged area, the class ends with some of the opinions of all students listed on the electronic blackboard not being magnified. There is. This may reduce the willingness to actively participate in classes (discussion) for students whose opinions are not enlarged. In addition, teachers may not be able to conduct a satisfactory class without being able to zoom in on other meaningful opinions (introducing or discussing opinions).

  In one aspect, an object of the present invention is to provide support for selecting a part of answers to be displayed on a display device from a plurality of answers.

In one mode, the display control program of this case may make a computer perform the 1st control, the 2nd control, and the 3rd control . The first control, the first display state that displays a plurality of answers received from a plurality of terminals for the information to determine the answer may control Viewing device. Further, the second control is the selected in the first display state, the display device controls the second display state that displays a portion of the answer of the plurality of answers, the second The storage unit that stores information on the answer that is the target of the second display state may be updated based on the partial answer that is the target of the display state . Further, the third control selects a non-target answer in the second display state from the plurality of answers based on information stored in the storage unit, and selects a target answer in the second display state. The display device may be controlled to a third display state in which different display is performed depending on the selected non-target answer. The first display state may include a state in which each of the plurality of answers is displayed in a corresponding area. The third display state may include a state in which information relating to a position of a non-target answer in the second display state in the first display state is displayed. The information on the position is the direction of each non-target answer in the second display state in the first display state based on the partial answer displayed in the second display state. It may be information indicating.

  In one aspect, it is possible to provide support for selecting some answers to be displayed on the display device from a plurality of answers.

  The teacher terminal 3 and the student terminal 4 may also have a hardware configuration similar to that of the opinion display server 2 described above. When the teacher terminal 3 and the student terminal 4 are tablet terminals, the input / output unit 2e may include a touch panel in which an input device and a display device are integrated. In addition, the teacher terminal program 31 and the student terminal program 41 may be downloaded from the network 6 via the interface unit of the teacher terminal 3 and the student terminal 4, or stored and provided in a recording medium. It may be read by the reading unit of the terminal 4.

  The hardware configuration of the opinion display server 2 described above is an example. Therefore, hardware increase / decrease in the opinion display server 2 (for example, addition or omission of arbitrary blocks), division, integration in an arbitrary combination, addition or omission of buses, etc. may be performed as appropriate. The same applies to the hardware configurations of the teacher terminal 3 and the student terminal 4.

[1-3] Functional Configuration Example of Opinion Display Server Next, a functional configuration example of the opinion display server 2 according to an embodiment will be described with reference to FIG. As shown in FIG. 3, the opinion display server 2 can include a communication unit 210, an assignment presentation unit 212, an opinion acquisition unit 214, a display control unit 216, and a DB storage unit 220 exemplarily.

  The DB storage unit 220 stores the assignment DB 22, the student DB 23, and the assignment answer DB 24 shown in FIG. For example, the DB storage unit 220 is realized by at least a part of the storage area of the storage unit 2c illustrated in FIG. Each DB 22 to 24 will be explained in the explanation of each functional block of the opinion display server 2.

  The communication unit 210 communicates with the teacher terminal 3, the student terminal 4, and the electronic blackboard 5, respectively. For example, the communication unit 210 can be realized by at least part of the functions of the CPU 2a and the interface unit 2d shown in FIG. Information received by the communication unit 210 is transferred to each corresponding functional block, and information from each functional block is transmitted to the teacher terminal 3, the student terminal 4, or the electronic blackboard 5. Hereinafter, for the sake of convenience, description will be made on the assumption that each functional block directly transmits / receives information to / from the teacher terminal 3, the student terminal 4, or the electronic blackboard 5.

  The assignment presentation unit 212 causes the teacher terminal 3 to select an assignment in response to a request from the teacher terminal 3 and presents the assignment selected by the teacher terminal 3 to the student terminal 4.

  As an example, when the assignment presentation unit 212 receives a request for displaying the assignment selection screen 230 (see FIG. 5) issued from the teacher terminal 3 via the teacher terminal program 31, the assignment presentation unit 212 refers to the assignment DB 22 in the DB storage unit 220. Information on the assignment, for example, an assignment ID (Identifier) and assignment contents are acquired.

  The teacher terminal 3 accesses, for example, an IP (Internet Protocol) address of the opinion display server 2 or a URL (Uniform Resource Locator) such as a Web server provided by the opinion display server 2 to start selecting an assignment. By performing an operation (command issuance), a request for displaying the assignment selection screen 230 can be transmitted.

  An example of the task DB 22 is shown in FIG. The assignment DB 22 exemplarily includes information associated with an assignment ID that uniquely identifies the assignment, the contents of the assignment, and the response time limit of the assignment. The response time limit is the time from when an assignment is presented to the student terminal 4 until the end of the response time.

  As an example, the task DB 22 is associated with the task ID “0002” with the task content “What do you think about the acceptance of rubble?” And the response time limit “20 minutes”. In the following description, it is assumed that “0002” is selected as the assignment ID.

  When the task presentation unit 212 acquires the task ID and the task content as task information from the task DB 22 illustrated in FIG. 4, the task presenting unit 212 generates the task selection screen 230 using the acquired task information, and the generated task selection screen 230 The access destination information, for example, the URL is transmitted to the teacher terminal 3.

  An example of the assignment selection screen 230 is shown in FIG. For example, the assignment selection screen 230 includes a selection button for selecting an assignment, an assignment ID, an assignment content, an assignment transmission button for sending the selected assignment to the opinion display server 2, and a cancel button for canceling the assignment selection. included.

  The teacher uses the input / output unit (corresponding to the input / output unit 2e in FIG. 2) of the teacher terminal 3 to select an arbitrary assignment button for the assignment selection screen 230 displayed by the teacher terminal program 31 such as a web browser. Check the box and press the assignment transmission button. When the assignment is selected in this way, the teacher terminal 3 transmits the assignment ID of the selected assignment and the assignment transmission request to the opinion display server 2.

  Upon receiving the assignment transmission request and the assignment ID from the teacher terminal 3, the assignment presentation unit 212 acquires the assignment contents corresponding to the received assignment ID from the assignment DB 22, and uses the acquired assignment contents to answer a screen 240 (see FIG. 7). ) And the information on the generated answer screen 240 is transmitted to the student terminal 4.

  Note that the assignment presentation unit 212 can specify information of the student terminal 4 that is the transmission destination of the information on the answer screen 240, for example, an IP address, by referring to the student DB 23 illustrated in FIG.

  As shown in FIG. 6, in the student DB 23, for example, a student ID for uniquely identifying a student, a student name (or student name), an IP address of a student terminal 4 distributed to the student, and a student seat Information associated with the seat information representing is included. The seat information is information representing the seat position of the student by row and column numbers, and corresponds to the display position of the answer on the list screen 250 (see FIG. 9) displayed on the electronic blackboard 5. When the answer is displayed on the list screen 250 by arrangement based on another rule, the student DB 23 has various position information such as a matrix based on another rule and a vector from the reference position instead of the seat information. May be set.

  An example of the answer screen 240 is shown in FIG. The answer screen 240 exemplarily shows an assignment content (and assignment ID), an approval / disapproval selection button, an opinion input field for inputting an opinion on the assignment content, and an input opinion to the opinion display server 2 “Send to teacher” A button and an opinion clear button for clearing the input contents in the opinion input field are included. The approval / disapproval selection button is a button for selecting approval / disapproval with respect to the task content, and can be selected as an approval or disagreement.

  The information on the answer screen 240 may be an access destination to the answer screen 240, for example, a URL, or the answer screen 240 itself, for example, an html (Hyper Text Markup Language) file. When the student terminal 4 has a screen generation function, the opinion display server 2 may omit the generation of the answer screen 240 and transmit the assignment content to the student terminal 4. The same applies to the following description.

  In addition, when the assignment presentation unit 212 transmits the assignment (information on the answer screen 240) to the student terminal 4, the assignment presentation section 212 updates the assignment answer DB 24.

  An example of the problem answer DB 24 is shown in FIG. As shown in FIG. 8, the assignment answer DB 24 exemplarily includes information associated with assignment ID, student ID, approval / disapproval and opinion contents included in the answer received from the student terminal 4, and a displayed flag. It is. The displayed flag is information indicating whether or not the answer displayed on the list screen 250 has been partially enlarged (highlighted), and is used in processing by the display control unit 216 described later.

  For example, when the assignment is transmitted to the student terminal 4, the opinion display unit 212 adds the assignment of the assignment ID of the assignment transmitted to the student terminal 4 to the assignment ID DB 24 for the student ID of the destination student terminal 4. To do.

  The opinion acquisition unit 214 receives an answer to the assignment transmitted from the student terminal 4 at a predetermined timing, and updates the assignment answer DB 24.

  In the student terminal 4 that has received the information on the answer screen 240 from the opinion display server 2, the following operations are performed by the student.

  For example, the student agrees or disagrees with the answer screen 240 (see FIG. 7) displayed by the student terminal program 41 using the input / output unit of the student terminal 4 (corresponding to the input / output unit 2e in FIG. 2). Check the approval / disapproval selection button and input the opinion in the opinion input field. When the input or the like is completed, the student presses a “send to teacher” button.

  When the transmission of the answer is instructed in this way, the student terminal 4 transmits the student ID set in the own terminal, the selected approval / disapproval, and the input opinion character string to the opinion display server 2.

  When the opinion acquisition unit 214 receives the response transmitted from the student terminal 4 at the time of the submission of the response, the received approval / disapproval and opinion are received with respect to the received student ID entry among the task IDs presented in the task response DB 24. Set (register) the contents.

  The opinion acquisition unit 214 acquires an answer from the student terminal 4 until the answer limit time expires after the assignment presentation unit 212 transmits the assignment to the student terminal 4, and updates the content of the above-described assignment answer DB 24 To do. For this reason, it is preferable that the opinion acquisition unit 214 acquires the assignment transmission time and the response time limit for the assignment set in the assignment DB 22 when the assignment presentation unit 212 transmits the assignment to the student terminal 4, for example. .

  Up to this point, the opinion acquisition unit 214 has been described as acquiring an answer transmitted from the student terminal 4 at a predetermined timing. However, the present invention is not limited to this. For example, the opinion acquisition unit 214 may transmit a polling request to the student terminal 4 periodically or at a predetermined timing, and receive an answer from the student terminal 4 as a response to the polling request.

  The display control unit 216 performs various controls related to the screen displayed on the electronic blackboard 5 and the teacher terminal 3. As illustrated in FIG. 3, the display control unit 216 can include, for example, a list generation unit 216a, a partial enlargement control unit 216b, and a non-displayed opinion presentation unit 216c.

  The list generation unit 216a generates a list screen 250 of answers to be displayed on the electronic blackboard 5 and the teacher terminal 3 (see FIG. 9). For example, when the assignment presentation unit 212 transmits the assignment to the student terminal 4, the list generation unit 216a generates, for example, a matrix-like list screen 250 indicating the submission status of responses from the student terminal 4, and information on the generated list screen 250 Is transmitted to the electronic blackboard 5 and the teacher terminal 3 to be displayed.

  An example of the list screen 250 displayed on the electronic blackboard 5 is shown in FIG. The list screen 250 exemplarily includes an assignment content 251, an opinion display area 252, a partial enlarged display button 253, and an end button 254 for ending the display of the opinion on the electronic blackboard 5. The partial enlargement display button 253 is a button for enlarging and displaying an opinion of a predetermined area (enlarged area) 252b (see FIG. 10) including an opinion of the area 252a selected and activated. The teacher terminal 3 may also display a list screen 250 similar to that in FIG.

  In the opinion display area 252, the opinions of the students from the corresponding student terminals 4 are displayed in a matrix in an arrangement designated by the row and column of the seat information in the student DB 23. In other words, it can be said that the list screen 250 is a screen that displays each of a plurality of answers in a corresponding area. Hereinafter, when the position or area of a specific opinion is indicated in the opinion display area 252, the row and column numbers may be represented as (x, y), respectively, as x and y.

  Each opinion can be alternatively selected (activated) / deselected by, for example, an operation on the teacher terminal 3 or the electronic blackboard 5 using a mouse or a touch panel. Hereinafter, the activated active opinion area (see the area surrounded by the broken line in FIG. 9) is referred to as an active area 252a or simply an area 252a. The display control unit 216 may determine, for example, an opinion in an area touched (clicked) by an operation on the touch panel as an active opinion, clicked with a cursor by a mouse operation, or simply placed on the front. Opinions in other areas may be judged as active opinions.

  In each opinion area, approval / disapproval / opinion content and student name may be displayed. In the example of FIG. 9, for the sake of convenience, only “opinion 1” in (1, 1) displays the approval / disapproval / opinion content and the student name, but in actuality other opinions (“opinion 2” to “ This information is also displayed in the opinion 42 "). If the opinion display server 2 has not received an answer from the student terminal 4, “not received” (and student name) is displayed. For example, immediately after the generation of the list screen 250 (immediately after the transmission of the assignment), the opinion display server 2 has not received an answer from the student terminal 4, so “not received” is displayed for all the opinions in the list screen 250. The

  Various operations such as selection of an opinion and pressing of a button on the list screen 250 displayed on the electronic blackboard 5 are performed by an operation of the teacher terminal 3 or the electronic blackboard 5 by a teacher or the like. This operation includes, for example, an operation through an input unit such as a touch panel of the electronic blackboard 5, an instruction from the teacher terminal 3 through an interface unit of the electronic blackboard 5, and a teacher terminal that is synchronized with the list screen 250 of the electronic blackboard 5. The operation of the list screen 250 displayed in 3 may be included. Hereinafter, unless otherwise noted, operations similar to the above can be basically performed on other screens displayed on the electronic blackboard 5.

  The list generation unit 216a obtains, for example, the task content from the task DB 22, the student name and seat information (matrix) corresponding to the student ID from the student DB 23, and the pros and cons and the opinion content corresponding to the task ID from the task answer DB 24, respectively. Thus, the list screen 250 shown in FIG. 9 can be generated.

  The list generation unit 216a updates the list screen 250 at a predetermined timing, for example, every time the opinion acquisition unit 214 receives an answer from the student terminal 4 and updates the assignment answer DB 24, and the updated list screen 250 is displayed on the electronic blackboard 5. And can be displayed on the teacher terminal 3.

  As described above, the list generation unit 216a controls at least one of the teacher terminal 3 and the electronic blackboard 5 in the first display state in which a plurality of answers received from the plurality of student terminals 4 are displayed with respect to information for which answers are sought. It can be said that this is an example of the first control means.

  When the partial enlargement button 253 is pressed in a state where any opinion is selected (becomes an active opinion) on the list screen 250 shown in FIG. 9, the partial enlargement control unit 216 b displays the electronic blackboard 5 and the teacher terminal 3. On the other hand, opinion partial enlarged screens 260 and 270 (see FIGS. 11 and 12) in a predetermined area 252b including the active opinion are displayed, respectively.

  In other words, the partial enlargement control unit 216b controls the electronic blackboard 5 to the second display state that displays some of the plurality of answers selected in the first display state. It can be said that it is an example of means. Similarly, it can be said that the partial enlargement control unit 216b is an example of a fourth control unit that controls the teacher terminal 3 to the fourth display state in which the partial answer is displayed.

  As an example, the partial enlargement control unit 216b presses the partial enlargement display button 253 when “opinion 32” at the position (5, 4) (that is, 5 rows, 4 columns) shown in FIG. 9 is in an active state. Then, as illustrated in FIG. 10, the region 252b in the range of (4, 3) to (6, 5) is selected as the enlarged region (selected region) (see the shaded region in FIG. 10).

  In the example of FIG. 10, the number of opinions in the expanded area 252b including the active opinion area 252a (x, y) is nine (x-1, y-1) to (x + 1, y + 1). However, it is not limited to this. The number of opinions in the enlarged area 252b includes the size of the displayable area (the entire area, for example, the display area 252 shown in FIG. 9) of the electronic blackboard 5, the format of the opinion (font, character size, etc.), the size of the classroom ( The distance can be any number according to various factors such as the distance from the electronic blackboard 5). As an example, when the number of opinions to be magnified is four, the magnified area 252b may be (x, y) to (x + 1, y + 1), and when the number of opinions is six, the magnified area 252b is (x-1). , Y) to (x + 1, y + 1). When the number of opinions to be enlarged and displayed is one, the enlarged area 252b may be set as the active area 252a (x, y).

  An example of a partial enlarged display on the electronic blackboard 5 is shown in FIG. As shown in FIG. 11, the partial enlarged screen 260 displayed on the electronic blackboard 5 exemplarily displays a “list” that changes to a task content 261, a partially expanded enlarged opinion display area 262, and a list screen 250. A “return to display” button 263 and an end button 264 are included. The partial enlargement screen 260 is an area displayed instead of the list screen 250 or on the front surface of the list screen 250. In the display area 262, the opinions of students included in the enlarged area 252b are displayed in an enlarged manner.

  An example of the partial enlarged display on the teacher terminal 3 is shown in FIG. As shown in FIG. 12, the partial enlarged screen 270 displayed on the teacher terminal 3 exemplarily has the same task content 271 as the partial enlarged screen 260 shown in FIG. 11, and the opinion of the enlarged region 252 b including the active region 252 a. Display area 272, a “return to list display” button 273, and an end button 274. The partial enlarged screen 270 further includes up / down / left / right arrows 275 for moving the enlarged region 252b in the list screen 250 and a “display undisplayed opinion” button 276. Note that this button 276 is not essential, and the enlarged region 252b may be moved by an operation (flick operation) for tracing the screen.

  The “display undisplayed opinion” button 276 is a button for displaying an opinion that has not been enlarged (not displayed) on the partial enlargement screen 260 (270), and is a process of the undisplayed opinion presentation unit 216c described later. Is what you call. The end button 274 is a button for ending the display of the opinion on the electronic blackboard 5 and the teacher terminal 3.

  In the teacher terminal 3, when the enlarged area 252b is moved by the operation of the arrow 275 on the partial enlarged screen 270, the opinion displayed on the display area 272 of the partial enlarged screen 270 is updated and the partial enlarged screen of the electronic blackboard 5 is displayed. The display area 262 of 260 can be updated similarly (in conjunction).

  For example, when the direction is designated by the arrow 275, the partial enlargement control unit 216b shifts the active area 252a in the designated direction based on the seat information of the student DB 23, and sets the new area to be shifted as the active area 252a. select. Then, the partial enlargement control unit 216b enlarges and displays the opinion of the enlarged area 252b including the new active area 252a on the display areas 262 and 272 of the partial enlarged screens 260 and 270, respectively.

  The partial enlargement control unit 216b selects an area obtained by shifting the enlargement area 252b itself in the designated direction as a new enlargement area 252b, and the opinions of the selected new enlargement area 252b are displayed in the display areas 262 and 272, respectively. An enlarged display may be used.

  Thus, it can be said that the partial enlargement control unit 216b updates the display screen of some answers displayed in the second display state based on the positional relationship of the plurality of answers in the first display state. .

  An example of the transition of the enlarged region 252b is shown in FIG. For example, it is assumed that the opinion in the area 252b indicated by reference numeral A in FIG. 13 is enlarged and displayed in the display area 262 of the partial enlarged screen 260 of FIG. 11 and the display area 272 of the partial enlarged screen 270 of FIG. In this state, when the arrow 275 of the partial enlarged screen 270 is pressed in the order of up, right, up, up, and right, the display areas 262 and 272 of the partial enlarged screens 260 and 270 include lines or lines on the list screen 250. Opinions in the enlarged area 252b in which the columns are shifted one by one are sequentially displayed, and after the above operation of the arrow 275, opinions in the area 252b indicated by reference character B in FIG. 13 are displayed.

  The teacher can perform a class while moving the opinion enlarged and displayed on the electronic blackboard 5 in the list screen 250 through the operation using the arrow 275 described above.

  Here, the partial enlargement control unit 216b can record whether or not each of the opinions displayed on the list screen 250 has been partially enlarged. As an example, the partial enlargement control unit 216b has displayed the opinions enlarged in the display areas 262 and 272 of the electronic blackboard 5 and the teacher terminal 3 with respect to the corresponding opinion entry in the assignment answer DB 24 (see FIG. 8). A value indicating that the flag is displayed, for example, “1” can be set in the flag.

  In the example of FIG. 13, the partial enlargement control unit 216 b first sets “1” for the displayed flag for the nine opinions indicated by the symbol A. Next, when the upper part of the arrow 275 is pressed to shift the enlarged area 252b, the partial enlargement control unit 216b newly sets “1” to the displayed flag for the three opinions (3, 3) to (3, 5). Set. Thereafter, similarly, the partial enlargement control unit 216b sets “1” in the displayed flag for the opinion newly included in the enlarged region 252b. When the enlarged area 252b moves from the reference A to the reference B in FIG. 13, “1” is set in the displayed flag of the assignment answer DB 24 for the opinion in the shaded area (see FIG. 13).

  The undisplayed opinion presenting unit 216 c presents the undisplayed opinion that is not displayed on the partial enlarged screen 260 to the teacher terminal 3 based on the displayed flag that the assignment answer DB 24 holds.

  For example, the undisplayed opinion presenting unit 216c, when the “display undisplayed opinion” button 276 on the partial enlarged screen 260 in the teacher terminal 3 is pressed, a value indicating that the displayed flag is not displayed from the assignment answer DB 24, for example, Null or Acquire information on answers (opinions) that are “0” (1 is not set). Then, the undisplayed opinion presentation unit 216 c generates a list of undisplayed opinions based on the acquired information and presents the list of undisplayed opinions to the teacher terminal 3.

  Thus, the undisplayed opinion presentation unit 216c can easily acquire the undisplayed opinion based on the information regarding the answers displayed on the partial enlarged screens 260 and 270.

  There are various modes for presenting undisplayed opinions. Hereinafter, display examples of undisplayed opinions will be described with reference to FIGS. The following display example is a display example on the display unit of the teacher terminal 3 (corresponding to the input / output unit 2e in FIG. 2), and the electronic blackboard 5 is displayed even while the undisplayed opinion is displayed on the teacher terminal 3. The list screen 250 or the partial enlarged screen 260 shown in FIG. 9 is displayed.

(Display example 1 of undisplayed opinions)
For example, as shown in FIG. 14, the non-displayed opinion presentation unit 216c can generate a non-displayed opinion presentation screen 280a that displays a list of undisplayed opinions together with the partial enlarged screen 270 shown in FIG.

  As shown in FIG. 14, on the undisplayed opinion presentation screen 280a, for example, the reduced display area 281 of the partial enlarged screen 270, the “delete undisplayed list” button 282, the “return to list display” button 283, and the end A button 284 and an undisplayed opinion list display area 285 are included.

  In the reduced display area 281, the partial enlarged screen 270 shown in FIG. 12 is reduced and displayed. If there is a space for displaying the list display area 285 on the display unit of the teacher terminal 3 without reducing the partial enlarged screen 270, the partial enlarged screen 270 is displayed in the reduced display area 281 without being reduced. May be.

  The “delete undisplayed list” button 282 is a button for deleting the list display area 285, and changes the screen to a partially enlarged screen 270 shown in FIG. The “return to list display” button 283 changes the screen to a list screen (corresponding to the list screen 250 in FIG. 9). The end button 284 is a button for ending the display of the opinion on the electronic blackboard 5 and the teacher terminal 3.

  In the undisplayed opinion list display area 285, as shown in FIG. 14, for example, the approval / disapproval, the student name, the opinion content, and the “direction viewed from the current partial enlarged display” (hereinafter simply referred to as “direction”). Notation). The approval and disapproval and the content of the opinion are set in an entry whose displayed flag in the task answer DB 24 is not “1”. The student name is set in the student DB 23 and corresponds to the student ID of the corresponding entry in the assignment answer DB 24.

  “Direction” indicates the direction of each undisplayed opinion on the list screen 250 with reference to the partial enlarged screen 260 currently displayed on the electronic blackboard 5, and is represented by an arrow, for example. For example, an active region 252a may be used as a representative region of the partial enlarged screen 260 that serves as a reference for the “direction”. Note that seat information (coordinates) of undisplayed opinions may be displayed in the list display area 285 instead of or in addition to the “direction”.

  For example, the non-displayed opinion presentation unit 216c refers to the student DB 23, and displays each non-display based on the seat information of the student ID corresponding to the opinion of the active area 252a and the seat information of the student ID corresponding to each non-displayed opinion. Calculate the “direction” of the opinion.

  As an example, the undisplayed opinion presentation unit 216c sets (xn, yn) (n is a natural number) to (xn−yn) (n is a natural number) as the active region 252a and (xn−X) / (yn−). By obtaining (Y), the inclination of the “direction” from the active area 252a to the undisplayed opinion is obtained. In addition, the undisplayed opinion presentation unit 216c sets the direction of the “direction” arrow to be downward when xn> X, upward when xn <X, and / or right when yn> Y, yn <Y. In the case of, determination is made using conditions such as leftward.

  Further, in the undisplayed opinion presentation screen 280a shown in FIG. 14, the list of undisplayed opinions is displayed in the display area 262 or the reduced display area 281 of the partial enlarged screen 260 displayed on the electronic blackboard 5. The display area 272 of the partial enlarged screen 270 thus updated can be updated. As described above, the update is performed by transitioning from the list screen 250 displayed on the electronic blackboard 5 to the partial enlarged screen 260 or by instructing the movement of the enlarged region 252b by pressing the arrow 275 on the teacher terminal 3. Executed.

  When the enlarged area 252b moves, the active area 252a also moves, so that the “direction” displayed in the undisplayed opinion list display area 285 can change. This is because the “direction” is based on the active region 252a (or the enlarged region 252b).

  Further, due to the movement of the enlarged area 252b, an opinion that has not been displayed in the enlarged area 252b may be newly displayed in the enlarged area 252b, and “1” may be set in the displayed flag of the assignment answer DB 24. In this case, since the opinion has already been displayed in the enlarged area 252b, it is preferable to delete the opinion from the undisplayed opinion list display area 285.

  Therefore, the undisplayed opinion presentation unit 216c can update the undisplayed opinion list display region 285 when the enlarged region 252b is moved by the partial expansion control unit 216b.

  Updating the list display area 285 may include regenerating the list display area 285 based on the updated task answer DB 24 accompanying the movement of the enlarged area 252b. In addition, this update may include hiding from the list display area 285 the opinion for which “1” is newly set in the displayed flag with reference to the updated task answer DB 24. Further, this update may include recalculating the “direction” of each undisplayed opinion based on the active area 252a after the enlarged area 252b is moved.

  As described above, in the undisplayed opinion presentation screen 280a, the partial enlarged screen 270 (reduced display thereof) and the undisplayed opinion list display area 285 are displayed on one screen, so that the teacher can confirm the undisplayed opinions. Thus, it is possible to move the enlarged region 252b while considering the opinion content. Therefore, it is possible to efficiently move the enlarged region 252b and conduct a lesson, which is highly convenient.

  In the list display area 285, information on the position of the area corresponding to the answer not displayed on the partial enlargement screens 260 and 270 in the list screen 250 (display area 252), for example, the direction of the undisplayed opinion and the undisplayed opinion The coordinates are included. Therefore, since the teacher can easily grasp the moving direction of the enlarged area 252b to the undisplayed opinion, the teacher can efficiently move the enlarged area 252b and conduct a lesson, which is highly convenient.

The “direction” may include information on the distance from the active area 252a to the undisplayed opinion area. As an example, the length of the “direction” arrow may be set to a length corresponding to the distance. In this case, the undisplayed opinion presentation unit 216c calculates √ (| xn−X | ² + | yn−Y | ² ) as the distance, and multiplies the calculation result by an arbitrary coefficient in the “direction” arrow. It can be a length. Alternatively, the number of blocks (the number of opinions) for moving the enlarged area 252b from the active area 252a to the undisplayed opinion area may be written in the “direction” arrow as in “XX block”.

  As a result, the teacher can grasp the distance to the undisplayed opinion. For example, even when a plurality of undisplayed opinions are in the same direction, in which order the undisplayed opinions are displayed in the display area 262. Can be considered in consideration of the distance to the opinion in addition to the content of the opinion. Therefore, it is possible to efficiently move the enlarged region 252b and conduct a lesson, which is highly convenient.

(Display example 2 of undisplayed opinions)
Further, as shown in FIG. 15, the undisplayed opinion presentation unit 216 c omits the reduced display area 281 shown in FIG. 14 and expands and displays the undisplayed opinion list display area 285. May be generated.

  As shown in FIG. 15, the undisplayed opinion presentation screen 280 b includes, for example, an end button 284, an undisplayed opinion list display area 285, and a partial enlarged display button 286.

  The end button 284 and the undisplayed opinion list display area 285 are the same as those shown in FIG. In addition, the display area of the undisplayed opinion list display area 285 is larger than that shown in FIG. 14, and more hidden opinions can be displayed. The partial enlarged display 286 button is used to change the screen to a partial enlarged screen 270 (see FIG. 12) that is a screen before the undisplayed opinion presentation screen 280b is displayed.

  In this way, in the undisplayed opinion presentation screen 280b, more undisplayed opinions can be displayed in the list display area 285 than in the undisplayed opinion presentation screen 280a, so the teacher considers the opinion content of many undisplayed opinions. However, the enlarged region 252b can be moved. Therefore, it is possible to efficiently move the enlarged region 252b and conduct a lesson, which is highly convenient.

  In the undisplayed opinion presentation screen 280b, for example, when the partial enlarged display 286 button is pressed in a state where one undisplayed opinion is selected, a partial enlarged screen 270 in which the selected opinion is the active area 252a is displayed. May be.

(Display example 3 of undisplayed opinions)
Further, as shown in FIG. 16, the non-displayed opinion presentation unit 216 c may generate a non-displayed opinion presentation screen 280 c that displays a non-displayed opinion in a manner such as a partial enlarged screen 270.

  As illustrated in FIG. 16, the undisplayed opinion presentation screen 280 c exemplarily includes an end button 284, a partial enlarged display button 286, and a display area 287 for undisplayed opinions.

  The end button 284 and the partial enlargement display button 286 are the same as those shown in FIG. The undisplayed opinion display area 287 is an area in which a predetermined number (for example, nine) of undisplayed opinions is arranged in the same manner as the display area 272 of the partial enlarged screen 270.

  Each undisplayed opinion area in the display area 287 may display the approval / disapproval opinion contents, the student name, and the same “direction” as that set in the above-described opinion display area 285.

  Thus, on the undisplayed opinion presentation screen 280c, the undisplayed opinion is displayed together with the “direction” in the same manner as the display on the actual partial enlarged screen 270. Therefore, the teacher can visually grasp the undisplayed opinion, and can easily recognize the undisplayed opinion displayed in the display region 272 by the movement of the enlarged region 252b.

  Note that the number of undisplayed opinions in the display area 287 may be different from the number of opinions displayed in the display area 272 of the partial enlarged screen 270.

(Display example 4 of undisplayed opinions)
Further, as shown in FIG. 17, the undisplayed opinion presentation unit 216 c may generate a non-displayed opinion presentation screen 280 d that shows a region of undisplayed opinions on the list screen 250.

  As illustrated in FIG. 17, the undisplayed opinion presentation screen 280 d exemplarily includes an end button 284, a partial enlarged display button 286, and a display area 288 for undisplayed opinions.

  The end button 284 and the partial enlargement display button 286 are the same as those shown in FIGS. Opinions are arranged in the undisplayed opinion display area 288 in the same manner as the display area 252 of the list screen 250. Of these opinions, the undisplayed opinions are emphasized so as to be easily discriminated. ing. In the example of FIG. 17, the area of the undisplayed opinion is indicated by diagonal lines. Note that the display area 288 may also show an active opinion 252a.

  In the undisplayed opinion display area 288, for example, the undisplayed opinion area may be surrounded by a thick frame, or the background color may be different from the enlarged display opinion. In addition, the approval / disapproval of the hidden opinion, the content of the opinion, and the student name may be enlarged and displayed in front of the display area 288 by selecting the area of the undisplayed opinion, or the opinion of the adjacent area is enlarged. If already displayed, the font size or the like may be enlarged and displayed in the adjacent area.

  Thus, in the undisplayed opinion presentation screen 280d, the position of the undisplayed opinion on the list screen 250 is shown. Therefore, the teacher can grasp the relative position of the undisplayed opinion on the basis of the active area 252a, and can also grasp the absolute position of the undisplayed opinion on the list screen 250. Thereby, the lesson opinion displayed on the display area 272 can be easily recognized while the class can be performed by moving the enlargement area 252b efficiently.

  In the undisplayed opinion presentation screen 280d, for example, when the partially expanded display 286 button is pressed in a state where one undisplayed opinion is selected, the partially expanded screen 270 having the selected opinion as the active area 252a is displayed. May be displayed.

(Other display examples of hidden opinions)
Note that the method of presenting the undisplayed opinion by the undisplayed opinion presenting unit 216c is not limited to the method described above. For example, the undisplayed opinion presentation screens 280a to 280d shown in FIGS. 14 to 17 can be appropriately combined.

  As an example, as shown in FIG. 18, the undisplayed opinion presentation unit 216c displays the reduced area 281 of the undisplayed opinion presentation screen 280a shown in FIG. 14 and the display of the undisplayed opinion of the undisplayed opinion presentation screen 280c shown in FIG. You may generate the undisplayed opinion presentation screen 280e which combined the mode.

  In the undisplayed opinion presentation screen 280e illustrated in FIG. 18, information on the undisplayed opinion is displayed together with the “direction” instead of the list display area 285 of the undisplayed opinions on the undisplayed opinion presentation screen 280a illustrated in FIG. . The undisplayed opinion information is, for example, an arrow 275 displayed in the reduced display area 281 and is preferably displayed in the vicinity of the arrow 275 closest to the “direction” vector.

  Thus, in the undisplayed opinion presentation screen 280e, the partial enlarged screen 270 (reduced display thereof) and the undisplayed opinion are displayed on one screen. The undisplayed opinion is displayed together with the “direction” in the same manner as the display on the actual partial enlarged screen 270. Therefore, the teacher can confirm the undisplayed opinion and efficiently move the enlarged area 252b while considering the content of the opinion. In addition, it is possible to visually grasp the undisplayed opinion, and it is possible to easily recognize the undisplayed opinion displayed in the display region 272 by moving the enlarged region 252b.

  The undisplayed opinion presentation unit 216c can present the undisplayed opinion to the teacher terminal 3 in the manner shown in FIGS. The undisplayed opinion presentation unit 216c may display the undisplayed opinion on the electronic blackboard 5 instead of or together with the teacher terminal 3.

  As described above, the undisplayed opinion presentation unit 216c controls at least one of the teacher terminal 3 and the electronic blackboard 5 in the third display state in which the target answer and the non-target answer in the second display state are displayed differently. It can be said that this is an example of the third control means.

  As described above, in the opinion display system 1 according to the embodiment, the opinion display server 2 displays the undisplayed opinion that has not been enlarged and displayed on the electronic blackboard 5 on the teacher terminal 3 (the answer to the enlarged display target and It ’s displayed differently for non-target responses). Thereby, the teacher can move the enlarged region 252b while considering the opinion content of the undisplayed opinion. Therefore, it is possible to efficiently move the enlarged region 252b and conduct a lesson, which is highly convenient. That is, effective support for selecting a part of answers to be displayed on the electronic blackboard 5 from a plurality of answers can be provided.

[1-4] Operation Example of Opinion Display System Next, an operation example of the opinion display system 1 configured as described above will be described with reference to FIGS.

[1-4-1] Description of Overall Process in Opinion Display Server First, the overall process in the opinion display server 2 will be described with reference to FIG.

  As shown in FIG. 19, the opinion display server 2 executes an opinion acquisition process for presenting an assignment to the student terminal 4 and acquiring an answer (opinion) from the student terminal 4 (step S1).

  The opinion display server 2 executes a display control process for displaying the opinion acquired in the opinion acquisition process on the electronic blackboard 5 and the teacher terminal 3 (step S2).

  When the display control process is terminated by an instruction from the teacher terminal 3 or the electronic blackboard 5, the process is terminated.

[1-4-2] Explanation of Opinion Acquisition Processing Next, referring to FIG. 20, opinion acquisition processing (in FIG. 19) by the problem presentation unit 212, the opinion acquisition unit 214, and the display control unit 216 of the opinion display server 2. (See step S1).

  As illustrated in FIG. 20, upon receiving a request for displaying the assignment selection screen 230 from the teacher terminal 3, the assignment presentation unit 212 generates an assignment selection screen 230 (see FIG. 5) from the assignment DB 22, for example, the assignment selection screen 230. Is transmitted to the teacher terminal 3 (step S11).

  The assignment presentation unit 212 waits for reception of an assignment ID and assignment transmission request from the teacher terminal 3 (No route in step S12 and step S12), and receives the assignment ID and assignment transmission request (Yes route in step S12). Goes to step S13. In step S13, the task content corresponding to the task ID received by the task presentation unit 212 is acquired from the task DB 22, and the acquired task content is transmitted to the address of the student terminal 4 acquired from the student DB 23. Note that the assignment presentation unit 212 may create an answer screen 240 based on the contents of the assignment, and transmit the URL of the created answer screen 240 to the student terminal 4.

  The list generation unit 216a of the display control unit 216 causes the electronic blackboard 5 and the teacher terminal 3 to display a list (for example, a matrix-like list screen 250) indicating the reception status from the student terminal 4 (step S14).

  The opinion acquisition unit 214 acquires the response time limit corresponding to the presented task ID from the task DB 22 (step S15), and has received the student ID, the pros and cons / opinion character string, and the submission information, that is, the response from the student terminal 4. It is determined whether or not (step S16). If such information has not been received (No route in step S16), the process proceeds to step S19. On the other hand, when such information is received (Yes route in step S16), the opinion acquisition unit 214 records the received approval / disapproval and the opinion character string for the entry corresponding to the student ID in the assignment answer DB 24 (step S16). S17).

  The list generation unit 216a updates the list screen 250 displayed on the electronic blackboard 5 and the teacher terminal 3 by using the updated task answer DB 24 at a predetermined timing, for example, when the task answer DB 24 is updated (step S18). ).

  The opinion acquisition unit 214 determines whether or not the response time limit has elapsed since the task presentation unit 212 transmitted the task to the student terminal 4 (step S19), and when the response time limit has not elapsed (step S19). No route), the process proceeds to step S16.

  On the other hand, when the response time limit has elapsed since the transmission of the task (Yes route in step S19), the process ends.

[1-4-3] Description of Display Control Processing Next, with reference to FIG. 21, the display control processing (see step S2 in FIG. 19) by the display control unit 216 of the opinion display server 2 will be described.

  As shown in FIG. 21, with the list screen 250 being displayed on the electronic blackboard 5 and the teacher terminal 3, the display control unit 216 waits for reception of an instruction from the teacher terminal 3 (No route of step S21 and step S21). ). When receiving the instruction (Yes route in step S21), the display control unit 216 determines whether or not the received instruction is a partial enlargement request (see the partial enlargement display button 253 in FIG. 9) (step S22).

  When the received instruction is a partial enlargement request (Yes route in step S22), the display control unit 216 determines whether or not an active opinion has been selected, that is, whether any opinion has been selected and becomes an active opinion. It is determined whether or not (step S23). When the active opinion is not selected (No route in step S23), the display control unit 216 selects any opinion before pressing the partial enlargement display button 283 on the front surface of the list screen 250, for example, to select the active opinion Is displayed (step S24), and the process proceeds to step S21.

  On the other hand, when an active opinion is selected (Yes route in step S23), the partial enlargement control unit 216b of the display control unit 216 executes a partial enlargement display process based on the selected active opinion (step S25). Goes to step S21.

  If the received instruction is not a partial enlargement request (No route in step S22), the display control unit 216 determines whether or not the received instruction is an active opinion selection request (step S26). If the received instruction is an active opinion selection request (Yes route in step S26), the display control unit 216 highlights the selected opinion as an active opinion on the list screen 250 (step S27), and the process is performed in step S21. Migrate to

  When the received instruction is not an active opinion selection request (No route in step S26), the display control unit 216 determines whether or not the received instruction is an end request (see the end button 254 in FIG. 9) ( Step S28). If the received instruction is an end request (Yes route in step S28), the display control unit 216 hides the matrix (list screen 250) (step S29), and the process ends.

  On the other hand, when the received instruction is not an end request (No route in step S28), the process proceeds to step S21.

[1-4-4] Description of Partial Enlargement Display Process Next, the partial enlargement display process (see step S25 in FIG. 21) by the display control unit 216 of the opinion display server 2 will be described with reference to FIG.

  As shown in FIG. 22, the partial enlargement control unit 216b of the display control unit 216 partially enlarges and displays a predetermined number of opinions including the selected active opinion (opinions of the selected enlarged region 252b) on the electronic blackboard 5 (FIG. 22). 11 (see step S31). Further, the partial enlargement control unit 216b causes the teacher terminal 3 to display a predetermined number of opinions including the selected active opinion together with the undisplayed opinion display button 276 (see the partial enlargement screen 270 in FIG. 12) (step S32). ).

  At this time, the partial enlargement control unit 216b sets “1” in the displayed flag of the assignment answer DB 24 for all the opinions displayed in the display areas 262 and 272 of the partial enlargement screens 260 and 270 (step S33).

  Further, the display control unit 216 waits for reception of an instruction from the teacher terminal 3 (No route in step S34). When the instruction is received (Yes route in step S34), the display control unit 216 determines whether or not the received instruction is a request for displaying an undisplayed opinion (see the “display undisplayed opinion” button 276 in FIG. 12). (Step S35). When the received instruction is a request for displaying a non-displayed opinion (Yes route in step S35), the non-displayed opinion presenting unit 216c executes a non-displayed opinion display process based on the assignment answer DB 24 (step S36), and the process is a step. The process proceeds to S34.

  When the received instruction is not a display request for an undisplayed opinion (No route in step S35), the display control unit 216 determines that the received instruction is an active opinion (a movement request for the enlarged area 252b) (arrow 275 in FIG. 12). It is determined whether or not (refer to step S37). When the received instruction is an active opinion movement request (Yes route in step S37), the partial enlargement control unit 216b executes a display opinion movement process based on the received instruction (movement direction) (step S38). Control goes to step S34.

  If the received instruction is not an active opinion movement request (No route in step S37), the display control unit 216 determines whether the received instruction is a list display request (see the “return to list display” button 273 in FIG. 12). It is determined whether or not (step S39). If the received instruction is a list display request (Yes route in step S39), the display control unit 216 acquires the pros and cons / opinion character strings of the students from the assignment answer DB 24 and forms a matrix on the teacher terminal 3 and the electronic blackboard 5. Is displayed (step S40), and the process ends.

  When the received instruction is not a list display request (No route in step S39), the display control unit 216 determines whether or not the received instruction is an end request (see the end button 274 in FIG. 12) (step S41). ). When the received instruction is an end request (Yes route in step S41), the partial enlargement display process ends, and the process proceeds to step S29 in FIG. That is, in this case, the display control unit 216 hides the matrix and ends the process.

  On the other hand, when the received instruction is not an end request (No route in step S41), the process proceeds to step S34.

[1-4-5] Description of Undisplayed Opinion Display Processing Next, with reference to FIG. 23, undisplayed opinion display processing (see step S36 in FIG. 22) by the display control unit 216 of the opinion display server 2 will be described. .

  As shown in FIG. 23, the undisplayed opinion presenting unit 216c of the display control unit 216 acquires one or a plurality of undisplayed opinions whose displayed flag is not “1” (indicating undisplayed) from the assignment answer DB 24 ( Step S51).

  Further, the undisplayed opinion presentation unit 216c acquires the position of the acquired undisplayed opinion (row, column) and the position of the active opinion (row, column) from the student DB 23 using the student ID as a key (step S52). ). Note that the position (row, column) of the active opinion may be acquired before step S51.

  Next, the undisplayed opinion presentation unit 216c calculates, for each row and column, the difference between the position of the undisplayed opinion and the position of the active opinion for each of the acquired undisplayed opinions (step S53). The undisplayed opinion presentation unit 216c determines the direction and length of the “direction” arrow based on the difference (row, column) calculated for each acquired undisplayed opinion (step S54).

  The undisplayed opinion presentation unit 216c uses the content of the acquired undisplayed opinion, the student name, and the determined “direction” arrow to display a list screen of undisplayed opinions (for example, the undisplayed opinion display screen 280a to FIGS. 280e etc.) is generated and the URL is transmitted to the teacher terminal 3 (step S55).

  Next, the display control unit 216 waits for reception of an instruction from the teacher terminal 3 (No route in step S56 and step S56). When receiving an instruction from the teacher terminal 3 (Yes route in step S56), the display control unit 216 determines whether or not the received instruction is an active opinion movement request (see, for example, the arrow 275 in FIGS. 14 and 18). Determination is made (step S57). When the received instruction is an active opinion movement request (Yes route in step S57), the partial enlargement control unit 216b executes a display opinion movement process based on the received instruction (movement direction) (step S58). The process proceeds to step S51.

  If the received instruction is not an active opinion movement request (No route in step S57), the display control unit 216 determines whether or not the received instruction is a request for erasing an undisplayed opinion list screen (partial enlarged display request). Is determined (step S59). The received instruction is a request for erasing an undisplayed opinion list screen (see the “Erase hidden list” button 282 in FIGS. 14 and 18) or a partial enlarged display request (partial enlarged display button 286 in FIGS. 15 to 17). (Refer to step S59), the process proceeds to step S60.

  In step S60, the undisplayed opinion presentation unit 216c deletes the undisplayed opinion list screen, displays only the enlarged opinion display on the teacher terminal 3 (displays the partially enlarged screen 270), and the process ends.

  When the received instruction is not a request for deleting the undisplayed opinion list screen (partial enlarged display request) (No route in step S59), the display control unit 216 determines that the received instruction is a list display request (in FIGS. 14 and 18). It is determined whether or not it is “return to list display” button 283) (step S61).

  When the received instruction is a list display request (Yes route of step S61), the display control unit 216 acquires the pros and cons / opinion character strings of the students from the assignment answer DB 24 and forms a matrix on the teacher terminal 3 and the electronic blackboard 5 (Step S62). At this time, since the screen displayed on the teacher terminal 3 is a list screen (see the list screen 250 in FIG. 9), the undisplayed opinion display process is ended and the partial enlarged display process is also ended. The process proceeds to step S21. That is, in this case, the display control unit 216 waits for reception of an instruction from the teacher terminal 3 with the list screen 250 displayed (No route in step S21 and step S21).

  When the received instruction is not a list display request (No route in step S61), the display control unit 216 determines whether or not the received instruction is an end request (see the end button 284 in FIGS. 14 to 18). (Step S63). When the received instruction is an end request (Yes route in step S63), the undisplayed opinion display process ends, the partial enlarged display process also ends, and the process proceeds to step S29 in FIG. That is, in this case, the display control unit 216 hides the matrix and ends the process.

  On the other hand, when the received instruction is not an end request (No route in step S63), the process proceeds to step S51.

[1-4-6] Explanation of Display Opinion Movement Processing Next, with reference to FIG. 24, display opinion movement processing (see step S38 in FIG. 22 and step S58 in FIG. 23) by the display control unit 216 of the opinion display server 2 ).

  As shown in FIG. 24, the partial enlargement control unit 216b creates a new opinion that has been moved one column or one line in the designated movement direction from the current active opinion (the opinion of the currently selected active region 252a). It is highlighted as an active opinion (step S71).

  Next, the partial enlargement control unit 216b displays a predetermined number of opinions including a new active opinion, that is, opinions of the enlarged region 252b including the new active region 252a, as a display area of the partial enlargement screen 260 (see FIG. 11) of the electronic blackboard 5. It is displayed on 262 (step S72). Further, the partial enlargement control unit 216b displays a predetermined number of opinions including a new active opinion in the display area 272 of the partial enlargement screen 270 (see FIG. 12, FIG. 14, or FIG. 18) of the teacher terminal 3 (step S73). ).

  Then, the partial enlargement control unit 216b sets “1” in the displayed flag of the assignment answer DB 24 for all the opinions displayed in the display areas 262 and 272 (step S74), and the process ends.
