When the [Complete] user operation is performed (step S210 (Yes)), the calculation data transmission / reception process (dedicated QR application) being executed is terminated.

  The data “calculator unique ID, calculation function type (statistical calculation function and calculation type), calculation target data (or calculation result data), setting information acquired from the scientific calculator 10 by the communication device with camera (smartphone or the like) 20 The “others” is configured to be obtained by converting the data into a two-dimensional code (QR code) in the scientific calculator 10 and photographing and analyzing the data with the camera-equipped communication device (smartphone or the like) 20. However, the present invention is not limited to this, and a configuration may be adopted in which the wireless communication unit 16 of the scientific calculator 10 and the wireless communication unit 28 of the communication device 20 acquire by short-range wireless communication.

  Then, in the calculation server 30, two-dimensional codes (QR codes) QA, QB, QC corresponding to the scientific calculators 10 A, 10 B, 10 C of the students transmitted from the teacher's camera-equipped communication device (smartphone or the like) 20. The data of the contents (QR data) “Calculator unique ID, calculation function type (statistical calculation function and calculation type), calculation target data (or calculation result data), setting information, etc.” is the room of the above-mentioned room “dice…” The ID (group ID) “823C-38q1-4234-F28S” and the names “A-kun”, “B-kun”, and “C-san” are received in association with each other (step S301 (Yes)). The contents data (QR data) and name of the received two-dimensional code (QR code) QA, QB, QC are dedicated to the received room ID (group ID) “823C-38q1-4234-F28S”. Each student A, B, C is stored in the data area 322A (step S302).

  Then, in the following processing (steps S303 to S305), the calculation data of each student stored in the room ID-specific calculation data storage area 322 (322A) is displayed as image integrated data Ag integrated according to a plurality of conditions. Narrowing conditions (selection conditions) are initially set.

  First, the condition of whether to display all the calculated data of each student stored in the data area 322A (322B) of the same room ID (group ID) or display the latest data [duplicate ID display] Is set to “Yes” (display all data). In addition, the [Function narrowing] condition for whether to display the calculation data of all calculation functions or the calculation data of the selected calculation function is set to “No” (display data of all functions) Is set. Further, a condition [individual narrowing down] for selectively displaying individual calculation data as a display target is set to "do not" (step S303).

  Next, the condition [total (coalescence)] of whether the calculation data of each student is merged and integrated or integrated as a list is set to "do not" (step S304).

  Further, the type of the graph to be displayed as the image integration data Ag is set to a type corresponding to the calculation function of the calculation data to be displayed (step S305). The graph type includes A: box-and-whisker chart, B: pie chart, and C: bar chart when the calculation data to be displayed is the one-variable statistics calculation data with the statistical calculation function. , A: Scatter chart, B: Linear regression graph, C: Secondary regression graph. In addition, when the calculation data to be displayed is calculation data of a mathematical table calculation function, A: a graph of a functional expression corresponding to the numerical table. The type of the graph is selected as “A” and initialized.

  Specifically, since the calculation data stored in the data area 322A of the calculation data storage area 322 by room ID is univariate statistical calculation data by the statistical calculation function, the graph type is “A: box-and-whisker chart”. Initially set.

  Then, for each student's calculation data stored in the room ID-specific calculation data storage area 322 ("dice ..." 322A), as shown in FIG. ) [Duplicate ID display: Enable] [Function narrowing: Not performed] [Individual narrowing: Not performed] [Total (merging): Not performed] [Graph type: Box-and-whisker chart] Graph images GA, GB, A GC is generated, and image integration data Ag is generated in which the corresponding names “A-kun”, “B-kun”, and “C-san” are associated with each of the graph images GA, GB, and GC of the calculation data. Then, a room display screen GR including information on rooms corresponding to the image integration data Ag and the respective narrowing-down conditions (selection conditions) is generated and transmitted to the teacher's camera-equipped communication device 20 and displayed ( Step S306).

  In the room display screen GR (see FIG. 9A), the information on the corresponding room is the room name “room of the number of times the dice are visible” rn, room ID (group ID) “823C-38q1-4234-F28S “Id, comment“ Please roll the dice and enter the number of rolls in the statistics mode table and send it. ”It is displayed as rc. Further, each of the narrowing conditions (selection conditions) includes a “Duplicate ID display” selection button AL (when “Yes” is selected), a “Function narrowing” selection menu Mf (when “No” is selected), [Individual narrowing down] selection button ps (when “No” is selected), [Total (union)] selection button CB (“No” is selected), [Graph type] selection menu Mg (When box-and-whisker diagram ga is selected) Is displayed.

  As a result, each statistical calculation data of the number of times the dice that are input by the scientific calculators 10A, 10B, and 10C of each student when the dice are shaken 10 times is obtained from the corresponding room (group) “the number of times the dice are noticed. It can be easily integrated into the “room” and displayed as image integration data Ag in which box whisker charts (graph images) GA, GB, and GC are listed.

  Here, in the room display screen GR displayed on the teacher's camera-equipped communication device 20 (expanded projection display on the projector P), as shown in FIG. 9B, a bar graph of the [graph type] selection menu Mg When gc is touched and selected and the calculation server 30 determines that the change of the graph type is instructed (step S309 (Yes)), the changed graph type (bar graph) is designated as the display target. (Step S310).

  At this time, since the [total (merging)] selection button CB is still selected as “not done” by the initial setting (step S311 (No)), as shown in FIG. Condition (selection condition) [Duplicate ID display: Enable] [Function narrowing: Not performed] [Individual narrowing: Not performed] [Total (union): Not performed] and [Graph type: Bar graph] after change Graph images GA, GB, and GC are generated, and image integrated data Ag in which corresponding names “A-kun”, “B-kun”, and “C-san” are associated with each other is generated. Then, the room display screen GR after the condition change is generated in the same manner as described above, and transmitted to the teacher's camera-equipped communication device 20 and displayed (step S312).

  FIG. 10 is a diagram showing a display operation (part 2) of the room display screen GR including the image integration data Ag generated by the calculation server 30.

  For example, the statistical calculation data of the number of eyes obtained by rolling the dice 10 times by each student “A-kun”, “B-kun”, and “C-san” shown in FIG. 9B is displayed as bar graph graph images GA, GB, In the room display screen GR (image integration data Ag) listed as GC, the statistical calculation data for 100 times obtained by adding the number of eyes obtained by rolling the dice 90 times by each student is also added to each scientific calculator as described above. 10A, 10B, 10C is received by the calculation server 30 via the camera-equipped communication device 20.

  At this time, in the calculation data storage area 322 (322A) “room of the number of times the dice are noticed” of the calculation server 30, statistical calculation of the number of eyes obtained by rolling the dice 10 times for each student. Data (old data) and statistical calculation data (latest data) of the number of eyes shaken 100 times are stored.

  Here, the mathematical table calculation data inputted in the mathematical table mode (the mathematical table calculation function) which is completely unrelated to the statistical mode (the statistical calculation function) by the scientific calculator 10D of the other student “D-kun” is the same as described above. It is received by the calculation server 30 from the scientific calculator 10D via the camera-equipped communication device 20, and stored in the room-by-room ID-based calculation data storage area 322 (322A) “the room where the number of times the dice are visible”.

  Then, in the calculation server 30, as shown in FIG. 10A, the narrowing condition (selection condition) [display duplicate ID: display (display all data)] [narrow function: not (data of all functions) All the calculation data including old and new calculation data and calculation data of different calculation functions stored in the above-mentioned calculation data storage area 322 (322A) “room of the number of times the dice are noticed” , A graph image GA1 (old), GA2 (latest), GB1 (old), GB2 (latest),... Is integrated and the corresponding names “A-kun”, “B-kun”,. A room display screen GR of data Ag is generated and transmitted (steps S301 to S312).

  At this time, in the integrated image data Ag, the graph image GD of the numerical table calculation data input by the scientific calculator 10D of the student “D-kun” is also displayed in a list, so that the display cannot be unified. It becomes an obstacle to understanding to learn the number of times the dice roll out.

  Here, in the room display screen GR displayed on the teacher's camera-equipped communication device 20, as shown in FIG. 10B, the statistical mode icon f6 in the [Function narrowing down] selection menu Mf is touched to select. Then, in the calculation server 30, it is determined that the narrowing-down condition [function narrowing: not performed] is changed to [function narrowing: statistics] (step S307 (Yes)).

  Then, according to the refined narrowing condition (selection condition) [duplicate ID display: yes] [function narrowing: statistics] [individual narrowing: not done] [total (coalescence): not done] All new and old calculation data corresponding to “A-kun”, “B-kun”, and “C-san” are set as display targets (step S308).

  Thus, according to the changed narrowing condition (selection condition) [duplicate ID display: yes] [function narrowing: statistics] [individual narrowing: not done] [total (coalescence): not done] The graph image GD of the numerical table calculation data input by the scientific calculator 10D of “D-kun” is excluded, and the graph image GA1, GA2, GB1, GB2, GC1 of the graph type “C: bar graph” unified only to the statistical calculation data , GC2 is generated, and image integration data Ag in which the corresponding names “A-kun”, “B-kun”, and “C-san” are associated with each other is generated. Then, the room display screen GR after the condition change is generated in the same manner as described above, and transmitted to the teacher's camera-equipped communication device 20 and displayed (step S309 (No) → S311 (No) → S312).

  FIG. 11 is a diagram showing a display operation (part 3) of the room display screen GR including the image integration data Ag generated by the calculation server 30.

  As shown in FIG. 10 (A) → (B), the calculation function narrowing conditions (selection conditions) are narrowed down to statistical calculation data [duplicate ID display: enable] [function narrowing: statistics] [individual] In the room display screen GR corresponding to [Narrow down: Not] [Total (union): Not] [Graph type: Bar graph], the [Duplicate ID display] selection button AL is touched as shown in FIG. When the check mark is removed, the calculation server 30 determines that the narrowing condition [duplicate ID display: yes] is changed to [duplicate ID display: no] (step S307 (Yes)).

  Then, statistical calculation is performed according to the refined narrowing condition (selection condition) [duplicate ID display: not performed] [function narrowing: statistics] [individual narrowing: not performed] [total (coalescence): not performed] after the change. Only the latest calculation data corresponding to the data “A-kun”, “B-kun”, and “C-san” is set as a display target (step S308).

  Thus, according to the refined narrowing condition (selection condition) [duplicate ID display: not performed] [function narrowing: statistics] [individual narrowing: not performed] [total (coalescence): not performed] Graph images GA2, GB2, and GC2 of [Graph type: Bar graph] narrowed down to the latest statistical calculation data of you, B, and C are generated, and the corresponding names “A”, “B”, and “C” Is integrated and image integrated data Ag is generated. Then, the room display screen GR after the condition change is generated in the same manner as described above, and transmitted to the teacher's camera-equipped communication device 20 and displayed (step S309 (No) → S311 (No) → S312).

  Thereafter, as shown in FIG. 11 (A), each condition narrowed down to only statistical calculation data and the latest data [duplicate ID display: not] [function narrowing: statistics] [individual narrowing: In the room display screen GR corresponding to [not]] [total (union): not]] [graph type: bar graph], as shown in FIG. 11 (B), “A-kun”, “B-kun”, “C-san” 3 When the [individual narrowing down] selection button ps for the two graph images GA2, GB2, and GC2 is touched and a check mark is added, in the calculation server 30, the narrowing-down condition [individual narrowing: not performed] is set to [individual narrowing: (The latest data of “Mr. A”, “Mr. B”, and “Mr. C”)] is determined (step S307 (Yes)).

  Then, the refinement condition (selection condition) after the change [Duplicate ID display: Without] [Function refinement: Statistics] [Individual refinement: Yes (Latest data of “A-kun”, “B-kun”, “C-san”) ] Only the latest calculation data corresponding to statistical calculation data “Mr. A”, “Mr. B”, and “Mr. C” is set as a display target in accordance with [total (union): not] (step S308). .

  Then, in order to integrate the latest calculation data of “A-kun”, “B-kun”, and “C-san” individually narrowed down as display objects into a combined graph image, a [total (coalescence)] selection button CB is provided. When touched and highlighted, the calculation server 30 determines that the narrowing-down condition [total (coalescence): not] is changed to [total (coalescence): yes] (step S311 (Yes)).

  Then, all the calculation target data (“A-kun”, “B-kun”, “C-san”) corresponding to each of the above-mentioned filtering conditions [duplicate ID display: not] [functional filtering: statistics] [individual filtering: yes] For the latest statistical calculation data), the calculation function type of the data is the same calculation function (here, statistical calculation data), and the calculation type of the calculation function is also the same (here, a bar graph of one-variable statistics) It is determined and confirmed (step S313 (Yes)).

  Then, the latest statistical calculation data of “A-kun”, “B-kun”, and “C-san” that have been individually narrowed down as the display objects and determined to have the same calculation function type and calculation type (bar graph GA2, univariate statistics) For GB2 and GC2), integrated image data Agc is generated by combining the data. Then, a room display screen GR including the combined image integration data Agc is generated, transmitted to the teacher's camera-equipped communication device 20 and displayed (step S314).

  In step S313, the calculation function type is the same (here, the statistical calculation function) and the calculation type is the same for a plurality of calculation data set as display targets in accordance with the respective narrowing conditions (selection conditions). In this case, it is determined that the calculation data can be merged when it is a bar graph of one variable statistics. However, when all the calculation data set as display targets are all one variable statistics, In the case of two-variable statistics, it may be determined that the calculation data can be combined.

  If it is determined in step S313 that the calculation function type is different or the calculation type is different for a plurality of calculation data set as display targets according to the respective narrowing conditions (selection conditions) (step S313 ( No)), an unmerged error message is sent to the communication device 20 and displayed.

  As a result, with regard to “the number of times that the dice roll out”, which is the subject of the learning of this calculation, first, statistical calculation data of the number of times that each student rolls the dice 10 times is displayed as individual bar graphs GA, GB, After the integrated image data Ag (see FIG. 9 (B)) listed on the GC is generated and displayed, the statistical calculation data for 100 times including the number of eyes that each student rolls the dice 90 times is added. Is added to individual bar graphs GA2, GB2, and GC2 to generate and display the image integrated data Ag (see FIG. 10B) listed. Then, by displaying the image integrated data Agc (see FIG. 11 (B)) that combines the individual bar graphs GA2, GB2, and GC2 of each student of the statistical calculation data for 100 times, You will be able to clearly understand how the number of times that the dice appear is equal.

  In the calculation server 30, any room ID (group ID) stored in the room ID (group ID) storage area 224 is specified and received from the teacher's communication device (smartphone, PC, etc.) 20. When it is done (step S316 (Yes)), as described above, each narrowed-down information for setting the display target for the calculation data of each student stored in the corresponding calculation data storage area 322A (322B) by room ID (Selection condition) is initially set ([Duplicate ID display: Enable] [Function narrowing: Not performed] [Individual narrowing: Not performed] [Total (union): Not performed] [Graph type: A]) ( Steps S303 to S305).

  Similarly to the above, for each student's calculation data stored in the designated room ID-specific calculation data storage area 322A (322B), each of the initially set narrowing conditions (selection conditions) [duplicate ID display: display ] [Function narrowing: Not performed] [Individual narrowing: Not performed] [Total (coalescence): Not performed] [Graph type: A] Each graph image is generated, and students corresponding to each graph image are generated. Integrated image data Ag that is associated with each name and generated in a list is generated. Then, a room display screen GR including information on the room corresponding to the image integration data Ag and the operators of the respective narrowing-down conditions (selection conditions) is generated, and the teacher's camera-equipped communication device (smartphone, PC, etc.) 20 and displayed (step S306).

  Thereafter, when each of the narrowing-down conditions (selection conditions) is changed in accordance with a user operation on the room display screen GR displayed on the teacher's communication device 20, the calculation server 30 is similarly changed. , The integrated image data Ag (Agc) corresponding to the changed narrowing condition is generated and transmitted to the teacher's communication device 20 as the room display screen GR and displayed (steps S307 to S315).

  Therefore, according to the calculation server 30 in the calculation learning system having the above-described configuration, each calculation data (calculation) of the number of times the dice input by the scientific calculators 10A, 10B,. The function type “statistics” and the calculation type “one-variable statistics” are associated with the calculator ID and acquired by the teacher's camera-equipped communication device (smartphone or the like) 20. When the calculation server 30 receives each calculation data in which the room ID (group ID) of the room of the calculation task “the number of times the dice are visible” and the name of each student are received from the communication device 20 of the teacher, The received student names and calculation data are registered in the calculation data storage area 322A for each room ID (group ID).

  Then, if all the calculation data of each student is to be displayed or the latest data is to be displayed [Duplicate ID display] is set to “Yes” (all data is displayed), all calculation functions are calculated. Select individual calculation data when the selection condition [Filtering function] is "None" (displays data for all functions) to select whether to display data or calculation data of the selected calculation function. If the selection condition [individual refinement] to be displayed automatically is “None”, the selection condition [Total (coalescence)] of whether to combine and integrate the calculation data of each student is set to “None” ”. In addition, when the type of graph is the calculation data of the one-variable statistics by the statistical calculation function, A: box-and-whisker chart, and A: scatter chart when the calculation data of the two-variable statistics is used. In the case of calculation data of the number table calculation function, A: Initially set to a graph of a function formula corresponding to the number table.

  Then, in accordance with each of the initially selected selection conditions and graph types, image integration data Ag (Agc) is generated by listing or merging calculation data of each student set as a display target into a graph image, and corresponding. The room display screen GR is transmitted to the teacher's communication device 20 and displayed.

  When each of the initially set selection conditions and graph type is changed according to a user operation from the teacher's communication device 20, it is set as a display target according to each changed selection condition and graph type. Image integrated data Ag (Agc), which is a list or merged with each student's calculation data as a graph image, is generated and transmitted to the teacher's communication device 20 as a corresponding room display screen GR and displayed.

  As a result, not only can the calculation data of each student's scientific calculators 10A, 10B,... Be displayed as integrated data integrated into a room (group) for each calculation task, but also a selection condition for a display target arbitrarily selected by the user. According to the graph type, calculation data corresponding to the selection condition can be displayed as integrated data obtained by integrating the selected type of graph image.

  In the calculation server 30 of the embodiment, calculation data of each student from the teacher's camera-equipped communication device 20 is associated with room ID (group ID) and each name as two-dimensional code content data (QR data). In either case (S301, S302) or after that, the room ID (group ID) designated by the communication device 20 is received (step S316), the initial setting is performed first. The integrated image data Ag (Agc) is generated and transmitted according to the selected display target selection condition and the graph type.

  On the other hand, when the selection conditions and the graph type of the display target that are initially set are changed according to a user operation from the teacher's communication device 20, the selection conditions and the graph type that are initially set Are updated and registered for each selection condition and graph type after the change. Next, when calculation data of each student is received from the teacher's camera-equipped communication device 20 in association with a room ID (group ID) (S301, S302), or the room designated by the communication device 20 When an ID (group ID) is received (step S316), the image integrated data Ag (Agc) is generated and transmitted according to the selection condition and graph type of the display target that is updated after the change and is initialized. It is good.

  At this time, among the updated and initially set selection conditions, the selection function of [Function narrowing] is, for example, [Function narrowing: Yes (two-variable statistical calculation function)], and the teacher's camera is attached. When the calculation data of each student received from the communication device 20 is different in the calculation data of the one-variable statistical calculation function, an error message indicating that the calculation function is different is transmitted to the communication device 20 and displayed. Also good.

  In the above embodiment, an example is shown in which the teacher integrates the calculation data of the scientific calculators of each student in the classroom, but communication with a camera in which the same room ID (group ID) is stored, even if not in the same classroom If it is the apparatus 20, calculation data can be integrated between different classrooms. For example, if each student of the same group registers the same room ID (group ID) for group learning in his / her camera-equipped communication device 20, each student can use his / her own learning data for camera learning. The calculation data can be integrated by transmitting from 20 to the calculation server 30.

  In addition, each processing method by the calculation learning system described in each embodiment, that is, calculation processing by the scientific calculator (information display device) 10 shown in the flowchart of FIG. 5, the communication device with camera shown in the flowchart of FIG. Each method such as calculation data transmission / reception processing 20 and server processing by the calculation server 30 shown in the flowcharts of FIGS. 7 and 8 is a memory card (ROM card, RAM card, etc.) as a program that can be executed by a computer. ), A magnetic disk (floppy (registered trademark) disk, hard disk, etc.), an optical disk (CD-ROM, DVD, etc.), a semiconductor memory, and other recording media.

  Further, the program data for realizing each of the above methods can be transmitted on the communication network N in the form of a program code, and the program data is transmitted to the computer of the electronic device connected to the communication network N as a communication unit. By taking in, the above-mentioned calculation function, calculation data transmission / reception function, and server function can be realized.
