Description

  The present invention relates to an information display device such as an electronic blackboard or a personal computer (PC) equipped with a scientific calculator emulator, and a control program therefor.

  2. Description of the Related Art Conventionally, a graph scientific calculator has been used in an educational field to learn, for example, various functional formula calculation methods and graph trajectories when the functional formula is graphed.

  For example, when a student inputs an operation on a teaching material to perform calculation or displays it in a graph, and confirms it, the teacher himself / herself shows how to operate the calculator, which is shown in a demonstration or printed and distributed as an operation manual. Imitates the input operation, and confirms the calculation result displayed and the graph drawing trajectory.

  However, while the graphing scientific calculator is equipped with a wide variety of functions and can perform various calculations and display processes, in order to make full use of the various functions, an operation procedure corresponding to each of the various functions is memorized. Even if the teacher gives a demonstration or gives an operation manual printed and distributed to the student, it is not easy for the student to learn the operation procedure of the desired function.

  Therefore, for example, by causing the scientific calculator emulator installed on a personal computer (PC) to display an operation for the teacher to solve the problem in the teaching material, and showing the operation display to the student using a projector or the like, It is realized that students themselves can easily solve and display the same tasks by inputting their scientific calculators like teachers.

  Some conventional scientific calculators display menus with function names and function names being abbreviated to compensate for the narrow display area. Then, in the state where such a function name or function name is abbreviated and displayed in the menu, [HELP] instruction is given to display a detailed description and an input format instead of this display. There is a scientific calculator that can assist an inexperienced user by using an input instruction as input data as it is (see, for example, Patent Document 1).

  In the [HELP] instruction function in the conventional scientific calculator, the function name and function name displayed in the abbreviation on the user's own calculator can be displayed in an easy-to-understand manner as a detailed description and input format. It is only an explanation aid.

  For this reason, even if you input your own scientific calculator in the same way as the operation displayed by the teacher in the emulator of the scientific calculator, what will happen if the displayed form is different as a result? It is not possible to properly grasp whether it is wrong.

  The present invention has been made in view of such a problem, and is an information display device including a terminal emulator, which displays appropriate operation assistance information when an operation assistance request is received from the terminal. An object of the present invention is to provide an information display device and a control program for the information display device.

Each time it is done, the 95 pages of the teaching material data “Math 1” displayed on the teaching material display screen Gb are enlarged and displayed at a predetermined enlargement ratio (step S7).

  When it is determined that some operation has been performed on the calculator emulator screen Gemu (step S5 (Yes)), the process proceeds to e-Activity mode processing (see FIG. 5) (step SA).

  Here, in the text input screen GE of the calculator emulator screen Gemu, when the text “GRAPH Y = 3 / x” of the task displayed on the teaching material display screen Gb is input by the operation of the key input unit (26). (Step A1 (Yes)), the text of the input subject is displayed on the text input screen GE (Step A2).

  Here, the student also operates the key input unit 26 of the graph scientific calculator 20 to input the text “GRAPH Y = 3 / x” of the task, and the color display unit 27 as shown in FIG. 7 (B3). Are displayed on the text input screen GE (steps A1 (Yes), A2).

  Next, as shown in FIG. 7A4, the [F2] key of the key input section (26) displayed on the calculator emulator screen Gemu of the electronic blackboard 10 is designated by the mouse cursor Cu, and the lower end of the text input screen GE. When the function menu [STRP] arranged in the above is input (step A3 (Yes)), a strip list window Lst is displayed on the text input screen GE.

  Here, the student also operates the [F2] key of the graph scientific calculator 20 to input the function menu [STRP] (step A3 (Yes)), and the text input screen GE as shown in FIG. 7 (B4). A strip list window Lst is displayed on the top.

  Subsequently, in the electronic blackboard 10, the cursor key 26d of the calculator emulator screen Gemu is operated by the mouse cursor Cu to move the reverse cursor H of the strip list window Lst, and [Spread Sheet] for creating table data is designated. When the [EXE] key is operated as shown in FIG. 8 (A5), a spreadsheet (S-SHT) is displayed in the text input screen GE on which the subject “GRAPH Y = 3 / x” of the teaching material is input. The strip ST is inserted and displayed (step A4).

  Here, the student also operates the cursor key 26d of the graph scientific calculator 20 to specify [Spread Sheet] in the strip list window Lst, and operates the [EXE] key, as shown in FIG. 8 (B5). Then, the strip ST of the spreadsheet (S-SHT) is inserted and displayed in the text input screen GE in which the task “GRAPH Y = 3 / x” of the teaching material is input (step A4).

  When the electronic blackboard 10 designates the strip ST of the spreadsheet (S-SHT) displayed on the text input screen GE and operates the [EXE] key (steps A5 and A6 (Yes)), FIG. As shown in A6), a table data input screen Gs is displayed instead of the text input screen GE (step A7 (Yes) → A8).

  In the table data input screen Gs, the teacher moves the cell where the cursor Cu is located by operating the cursor key 26d, and draws the graph of the task “function y = 3 / x” displayed on the teaching material display screen Gb. Each x value (−3, −2.5,...) Given in “Let's see.” And each y value (−1, −1.2,...) Corresponding thereto are sequentially input and displayed. In this case, the x value and y value input to the cell where the cursor Cu of the table data input screen Gs is located are set in advance in the display SET UP mode to be described later in the empty area at the lower right of the screen Gs. Are displayed in numerical form according to the setting contents (Fix / Sci / Norm / Eng) related to the display of the table (step A8).

  Specifically, the display form of the input numerical value in the display setup mode in the scientific calculator emulator of the electronic blackboard 10 is set to (Norml: normal display). For this reason, as shown in FIG. 8 (A6), the y value [-1.2] input corresponding to the position of the cursor Cu on the table data input screen Gs is a free space at the lower right of the screen Gs. It is displayed in the area as it is in numerical form.

  Here, the student also specifies the strip ST of the spreadsheet (S-SHT) displayed on the text input screen GE of the graph scientific calculator 20 and operates the [EXE] key (steps A5 and A6 (Yes)). As shown in FIG. 8B6, a table data input screen Gs is displayed instead of the text input screen GE (steps A7 (Yes), A8). Then, similar to each x value and each y value input and displayed in accordance with the teacher operation on the table data input screen Gs (see FIG. 8A6) of the electronic blackboard 10, the student's own graph scientific calculator 20 is displayed. Each value is also input and displayed on the displayed table data input screen Gs (step A8).

  At this time, the y value [−1.2] input to the cell at the position of the cursor Cu on the table data input screen Gs of the electronic blackboard 10 is a numerical value as it is in the empty area at the lower right of the screen Gs as described above. Although displayed in the form [−1.2], the empty area at the lower right in the table data input screen Gs of the student graph scientific calculator 20 has a different numerical form [−1. ] Is displayed.

  Here, the student displays the numerical value input on the table data input screen Gs in the same manner as the operation display by the teacher on the electronic blackboard 10 in spite of the input operation of the graph scientific calculator 20 of the student. 1.2] and [-1. ], The cause of the difference is not understood, so when the [SHIFT] key and [OPTN] key are pressed simultaneously, the printed [HELP] is entered along the [OPTN] key (step A17 (Yes)).

  Then, the current processing mode (table data input mode) and the current processing data (table data memory 22b) in the scientific calculator 20 together with the operation assistance request “HELP” are sent from the student's graph scientific calculator 20 to the electronic blackboard 20. The data of the table data input screen Gs stored in (2) and the setting data relating to the display form of the table stored in the display setup data memory 22e are transmitted (step A18).

  When the electronic blackboard 10 receives the operation assistance request “HELP” transmitted from the student's graph scientific calculator 20 (step S8), the current electronic graph 20 in the graph scientific calculator 20 received together with the operational assistance request “HELP” is received. The processing mode (table data input mode) and the current processing data (the data on the table data input screen Gs and the setting data regarding the display form of the displayed table data that has been set up) are temporarily stored in the work area 12h (step S9). .

  If it is determined that the processing data of the graph scientific calculator 20 that has received the operation assistance request “HELP” is tabular data (step S10 (Yes)), as shown in FIG. 8 (A6 ′), The setting data 20SET relating to the display form of the display SET UP table data in the student graph scientific calculator 20 temporarily stored in the work area 12h and the scientific calculator emulator stored in the display SET UP data memory 12g of the electronic blackboard 10 The setting data Emu SET relating to the display form of the table data is compared (step S11).

  Here, there is different setting data (Display: Normal [normal display] between the display SET UP setting data 20SET received from the student graph scientific calculator 20 and the display SET UP setting data Emu SET in the scientific calculator emulator of the electronic blackboard 10. ] And Display: Fix0 [fixed integer display] is determined (step S12 (Yes)), as shown in FIG. 9 (A7), the display UP setting data having the difference is corrected. Operation auxiliary information HP ([SHIFT] [SET UP] Display: Fix0 → Display: Normal) and data Gs (20) of the table data input screen Gs having a difference temporarily stored in the work area 12h, It is displayed on the display unit 17 of the electronic blackboard 10 in comparison with the table data input screen Gs on the electronic blackboard 10 side (step S13).

  The student operates his / her own graph scientific calculator 20 according to the operation assistance information HP displayed on the display unit 17 of the electronic blackboard 10 as shown in FIG. 9 (B7), and displays it in the display SET UP data memory 22e. The setting data (Display: Fix0 [fixed integer display]) relating to the display form of the stored table data is corrected to (Display: Normal [normal display]) and input again (step A11 (Yes) → A12).

  Thus, the data display form on the table data input screen Gs displayed on the scientific calculator emulator screen Gemu of the electronic blackboard 10 operated by the teacher and the display on the display unit 27 of the graph scientific calculator 20 operated by the student are displayed. The data display form on the table data input screen Gs is unified, and the student can proceed with learning according to the operation display of the electronic blackboard 10 by the teacher without a sense of incongruity.

  In addition, there is a difference from the operation assistance information HP ([SHIFT] [SET UP] Display: Fix0 → Display: Normal) corresponding to the operation assistance request “HELP” transmitted from the graph scientific calculator 20 of a student. Since the data Gs (20) of the table data input screen Gs is displayed on the display unit 17 of the electronic blackboard 10 in contrast with the table data input screen Gs on the electronic blackboard 10 side, It is possible to notify a person who is making a setting difference in the display setup data regarding the display form of the table data, and the learning can proceed smoothly and more effectively.
