  When the e-Activity mode for performing the graph function learning process is selected and confirmed in the graph function calculator 10B of the learner (student), the strip execution process (see FIG. 19) for executing the exercise is started. The user-specified e-Activity file (for example, “ABC”) is read from various files registered in the memory card (external storage medium) 16 (step A1), as shown in FIG. An e-Activity screen Q having a graph response activation button [GRPH] Ba with an Auto icon “A” I is displayed on the liquid crystal display unit 13 (step A2).

  In this e-Activity screen Q, the exercise problem function expressions “Y1 = X2-1” and “Y2 = 2X-2” (J) written together with the text T “EX1> Answer the intersection” of the exercise (learning) content are displayed. In order to learn, when the graph exercise start button [GRPH • E] Be or the graph answer start button [GRPH] Ba is selected and the “EXE” key 12f is operated and input (step A3 (Yes)), first, the graph The drawing function is activated, and graph data Y1 and Y2 corresponding to the exercise problem function expressions “Y1 = X2-1” and “Y2 = 2X-2” are drawn and displayed as shown in FIG. Step A4).

  Then, in the e-Activity screen Q (see FIG. 20A), whether or not the graph answer start button [GRPH] Ba for automatically displaying the model analysis / answer of the exercise problem function formula is input ( Step A5 (Yes)) or whether the learner (student) operation input has been input for the graph exercise start button [GRPH · E] Be instructing the processing for analysis and answering (Step A5 (No)) ) Is judged.

  Here, for example, if it is determined that the graph exercise start button [GRPH • E] Be for instructing the processing for analyzing and answering according to the operation input of the learner (student) is input (step A5 ( No)), the user (student) enters the normal graph function operation state by his own manual operation.

  That is, when a feature point such as the intersection point P of the graph data Y1 and Y2 is to be found and displayed, a corresponding solving operation is executed and displayed according to a manual operation corresponding to the feature point to be found. .

  That is, when the intersection P of the graph data Y1 and Y2 is to be obtained and displayed according to the manual operation, first, by specifying the solution function (G-Solve) by the operation input of the function key “F5”, various graph functions can be obtained. Menu buttons Bsol for selecting and specifying the solution function are displayed along the lower end of the graph screen G.

(See FIGS. 18E to 18G).

  On the other hand, in the display state of graphs Y1 and Y2 corresponding to the exercise problem function formulas “Y1 = X2-1” and “Y2 = 2X-2” (J) shown in FIG. When it is determined that the graph answer start button [GRPH] Ba for automatic display has been operated (step A5 (Yes)), the user-specified e-Activity file read in step A1 In the final screen setting flag data (19h), it is determined whether or not the flag “1” indicating “exemplary display only on the final graph screen” is set (step A6).

  Here, when it is determined that the flag “1” indicating “exemplary display only on the final graph screen” is not set, that is, it is in the operation setting state in which automatic display is performed including the process of analysis and answer of the model (step A6 (No)), each command on the graph function operation after display execution “EXE” of the graph screen G, which is stored and registered as graph execution command data (19g) in the e-Activity file designated by the user The key data of the key “F5” (G-solve) → “F5” (ISCT) is sequentially read, and as shown in FIGS. 20 (C) → (D), each command key “F5” (G-solve). ) → Graph function operation corresponding to “F5” (ISCT) is executed (steps A7 and A8).

  That is, in this case, according to the reading of the key data of the instruction key “F5”, various solution functions for the graph function are selected along the lower end of the graph screen G as shown in FIG. A menu button Bsol for designating is displayed in an array, and secondly, the key data of the instruction key “F5” is read and displayed on the graph screen G as shown in FIG. The intersection point P of the graphs Y1 and Y2 is analyzed and displayed according to the coordinate coincidence point of the data of the graphs Y1 and Y2, and the XY coordinates [X = 1] [Y = 0] of the intersection point P are solved and displayed. The graph screen Gsol is displayed.

  As a result, the user (student) simply selects the graph response activation button [GRPH] Ba on the e-Activity screen Q and operates the “EXE” key 12f, so that the user can use his / her own graph scientific calculator 10B. Intersection points obtained by analyzing the intersection coordinates P from the drawing screens G of the graphs Y1 and Y2 corresponding to the exercise problem function formulas “Y1 = X2-1” and “Y2 = 2X-2” (J) by the actual graph processing operation The model analysis / answer screen up to the solution graph screen Gsol can be automatically displayed in order and confirmed.

  On the other hand, in the final screen setting flag data (19h) in the user-specified e-Activity file read in step A1, the flag “1” indicating “exemplary display only on the final graph screen” is set. If it is determined (step A6 (Yes)), each command key “F5” on the graph function operation stored and registered as the graph execution command data (19g) in the e-Activity file designated by the user. (G-solve) → "F5" (ISCT) key data is sequentially read, and the graph function operation corresponding to each instruction key "F5" (G-solve)-> "F5" (ISCT) is internally performed. However, externally, as shown in FIGS. 21A and 21B, the operating message M1 is displayed from the initial display state of the e-Activity screen Q, and the graphs Y1, Y2 are displayed. Update graph display screen G of the process with its intersection solving the drawing is omitted (step A9, A10).

  When the key data of the last command key “F5” (ISCT) stored and registered as the graph execution command data (19g) is read (step A10 (Yes)), as shown in FIG. In addition, the intersection point P of the graphs Y1 and Y2 corresponding to the exercise problem function formulas “Y1 = X2-1” and “Y2 = 2X-2” (J) is analyzed and displayed according to the coordinate coincidence point of the data of the graphs Y1 and Y2. In addition, the intersection solution graph screen Gsol on which the XY coordinates [X = 1] [Y = 0] of the intersection P are obtained and displayed is directly displayed as the final analysis result (step A11).

  Therefore, according to the e-Activity function of the second embodiment of the graph scientific calculator 10 having the above-described configuration, in the strip registration process in which the e-Activity screen Q is displayed in the e-Activity mode, the teacher issues a problem to the student. After drawing and displaying the graph screen G of the graphs Y1 and Y2 corresponding to the function expressions “Y1 = X2-1” and “Y2 = 2X-2”, graph feature points are displayed using the “F5” (G-solve) key. When the solution for the intersection coordinates P is input by the “F5” (ISCT) key and the intersection solution graph screen Gsol is displayed, the graph Y1 and Y2 are displayed after the drawing display. Each key data “F5” (G-solve) → “F5” (ISCT) for the solution command is sequentially registered in association with the graph response activation button [GRPH] Ba on the e-Activity screen Q. .

  Then, in the strip execution process in which the e-Activity screen Q after the strip registration process is displayed, when the graph answer start button [GRPH] Ba on the e-Activity screen Q is selected and executed, it is displayed. After the graph screen G of the graphs Y1 and Y2 corresponding to the exercise problem function expressions “Y1 = X2-1” and “Y2 = 2X-2” (J) is drawn and displayed, the graph answer start button [GRPH] Ba The graph feature point solving function is sequentially activated and the intersection coordinate P solving process is executed in accordance with each key data of the “F5” (G-solve) key + “F5” (ISCT) key registered in association with each other.
