In the 19K of workspace, follow the data of the interim storage of control and treatment of exercises mode by control part (CPU) 11 input and output.

The following describes e-Activity function according to first example of the chart function calculator 10 of described structure.

In the choice menus picture of the exercises mode that the operation of " MENU " key 12c in corresponding keys input part 12 input shows, select to be identified for to carry out the e-Activity mode that to handle as the study of the function calculation of problem on display part 13.Then, when the e-Activity of the generation registration that starts the policy paper be used to make the function calculation of carrying out described problem for learner (student) makes when handling (with reference to Fig. 5), show the not new e-Activity picture Q (with reference to Fig. 1) under the input state of every content, at first show the message of urging import file name.Here, when for example corresponding user as educator (teacher) operates the F of filename arbitrarily " 020512 " that imports the function calculation problem that shows this less important registration (step T1), then become the text input state of its learning content.Then, as the text T of learning content, for example when input shows " Maximum/Minimum Value Calculation ".Follow the filename F " 020512 " of described input and content text T " Maximum/Minimum ValueCalculaion " " Minimum Value ", storage (step T2) in the filename content text storer 19c of RAM 19 therewith.

In new e-Activity picture Q, generate demonstration in advance and be used to make the striped button SB of beginning as the guidance demonstration of the key operation process of the model of the function calculation problem of described text T input demonstration.

Here, generate when showing described striped button SB, become the input waiting status of the explanatory text arbitrarily that on its striped, will record and narrate when respective user operates in arbitrarily picture position.Then, in the button frame of described striped button SB, as its arbitrarily explanatory text for example import when storing among demonstration " Press[EXE] " " RUN ", the filename content text storer 19c in described RAM 19, become the show state (step T3) of the required purpose input of e-Activity picture Q.

Like this, be transfused under the state that shows generation the every of e-Activity picture Q, when specifying described striped button SB, when arranging " GUIDE " button B5 that shows (step T4) by the lower end of operation " F5 " key input on this picture Q, the guidance system that starts among Fig. 6 deals with, and becomes the input waiting status (step TP) of policy paper of following the key operation of finding the solution of the function calculation problem that this time shows for making on e-Activity picture Q.

When the guidance system in starting described Fig. 6 deals with (step TP), at first, shown in Fig. 7 (A), show that the new system that instructs of the variety of way setting button [nKEY] [1KEY] [AUTO] [END] [PLAY] of arranging the Production Editor who is used for the key operation policy paper is made picture H1.

Instruct new system to do among the picture H1 at this, it is respectively the setting button that is used for [n KEY] mode, [1 KEY] mode, [AUTO] mode that these 3 modes of [nKEY] [1 KEY] [AUTO] are set button.

[n KEY] mode, be when carrying out for the instructing of student, generation makes that manual input learns＜Manual Play for each key〉the mode of policy paper, make a corresponding policy paper that explains orally note (NOTE), in corresponding note input store (Manual) 19D of n key, store with a plurality of key data of sequence of operations.

[1 KEY] mode, be when carrying out for the instructing of student, generation makes that manual input learns＜Manual Play for each key〉the mode of policy paper, make a corresponding policy paper (for Manual Play) that explains orally note (NOTE), in corresponding note input store (Manual) 19E of 1 key, store with the key data of each key.

[AUTO] mode, be when carrying out for the instructing of student, order instruct to show a series of key operation simultaneously automatically input generate make confirm to learn＜AUTO Play the mode of policy paper, makes policy paper (for Auto of a corresponding explanation note with a plurality of key data of sequence of operations (NOTE)

Corresponding note input store (Manual) 19D of text memory 19C, n key, corresponding note input store (Manual) 19E of 1 key, corresponding note input store (Auto) 19F of n key, Auto Speed sets storer 19G, and e-Activity returns constant preserve (the step T5) of content former state of the policy paper of registering among the striped registration storer 19S that sets tag memory 19H composition in memory card (exterior storage medium) 16.

Like this, generate the memory card (exterior storage medium) 16 that registration has the e-Activity policy paper, as shown in above-mentioned Fig. 1, be removed, be installed among the chart function calculator 10B of student's side and use from the chart function calculator 10A of teacher's side.

Perhaps, corresponding above-mentioned a series of guidance system deals with (striped TP (P1～P7)), in the chart function calculator 10A of teacher's side, be created on the content of the policy paper of registering among the striped registration storer 19S, as shown in above-mentioned Fig. 2, the chart function calculator 10B that is sent to student's side by USB cable 18c and outside personal computer PC communication used afterwards.

The following describes in the chart function calculator 10B of student's side, abide by e-Activity policy paper that reads in from described memory card 16 or the e-Activity policy paper that reads in via the personal computer PC of outside, the student learns the action of occasion of the content of the problem that the teacher proposes.

When the e-Activity execution processing (striped execution processing) (with reference to Figure 11) of the study processing of function calculation is carried out in startup, the various files of registration are read the e-Activity policy paper startup (step U1) of user's appointment from memory card (exterior storage medium) 16, show the e-Activity picture Q (step U2) that the striped button SB that records and narrates " Minimum Value " " RUN " as shown in Figure 12 (A) is for example arranged on liquid crystal display part 13.

In this e-Activity picture Q, when specifying its striped button SB operation input " EXE " key 12f (step U3), start the guidance of carrying out by the key operation policy paper corresponding and handle (step U4) with this e-Activity picture Q.

Here, the key data of the key operation policy paper of representing in the operation show state (one) of (striped is carried out and handled) is handled in the e-Activity execution of following in Figure 12, for example shown in Figure 12 (A '), suppose by the guidance system under correspondence described [1 KEY] mode and deal with＜Manual Play [OPTN] [F4] [F6] [F1] [X that make, that in corresponding note input store (Manual) 19E of 1 Key of striped registration storer 19S, register, θ, T] [, ] [1] [, ] key data formed of 12 key steps of [2] [,] [3] [EXE].

That is when starting execution guidance processing, at first, shown in Figure 12 (B), be presented at the key guide data " OPTN " that instructs display key step " 001 " among the GK of key range, simultaneously, be presented among the comment field N and show that its first key that explains orally annotation data " INPUT[OPTN] " instructs picture G1.

When each guide data that instructs in accordance with this first key among the picture G1, during by student's operation " OPTN " key 12e, shown in Figure 12 (C), be presented at the key guide data " F4 " that instructs display key step " 002 " among the GK of key range, simultaneously, be presented among the comment field N and show that its second key that explains orally annotation data " INPUT[F4] " instructs picture G2.

When abideing by this second key when instructing each guide data operation " F4 " key among the picture G2, order similarly, the quadruple linkage that the triple bond that is shown as the key guide data " F6 " that shows key step " 003 " and explains orally annotation data " INPUT[F6] " instructs picture G3, show the key guide data " F1 " of key step " 004 " and explain orally annotation data " INPUT[F1] " instructs picture G4.

After this, when the 12 key of abideing by the key guide data " EXE " show final key step " 012 " and explaining orally annotation data " INPUT[EXE] " instructs picture G12, during by student's operation " EXE " key 12f, carry out the function calculation of " Minimum Value " corresponding with described a series of key operation input and handle.Then, show the result of calculation picture Ga of the calculation result data (19J) " FMin... " as Figure 12 (D) expression.

Thus, even the student does not for example extremely understand the method for operating of this chart function calculator 10B, Yi Bian can actually very simply carry out the problem that the function calculation of teacher's proposition is learnt in the key operation input on one side yet.

Then, the key of abideing by described final key step in correspondence instructs the key operation of picture to import, when being presented at the result of calculation picture Ga on the function calculation function of representing among described Figure 12 (D), return to set at the e-Activity of described striped registration storer 19S and set the expression (occasion of the sign of Strip Exit → ON) among the tag memory 19H, shown in Figure 12 (E), the key in this result of calculation picture Ga instructs display key guide data " EXE " among the GK of viewing area.

Under guidance system deal with＜Auto Play continuous combination each key data of chart of drawing demonstrations " Y=sin X " that make, that in corresponding note input store (Manual) 19E of 1key of striped registration storer 19S, register and each key data of the track that is used for the tracing display chart of after this, in n key correspondence note input store (Auto) 19F, registering.

That is by start to carry out instruct handling (step U4), be presented at first successively key instruct show among the GK of viewing area with the chart that is used to draw demonstration " Y=sin X "＜Manual Play corresponding each key guide data and each key of forming instructs picture Gn.

Then, when abideing by and described＜Manual Play by the student〉each corresponding key instructs the key operation input startup chart of picture Gn to draw function, when drawing the chart of demonstration " Y=sin X ", shown in Figure 13 (A), show that continuing key instructs picture Gn, instruct at key to be shown as the key guide data " F1 " that makes the function that starts the chart tracking among the GK of viewing area.

When abideing by the key guide data " F1 " that this key instructs picture Gn, during by student's operation " F1 " key, this order that continues is input conduct＜Auto Play automatically〉each key data of registration, start and carry out the chart following function, shown in Figure 13 (B), show to move show follow the tracks of on the chart of " Y=sin X " that pointer P forms＜Auto Play in key instruct picture Gt.

This＜Auto Play in key instruct among the picture Gt, also in its comment field N, show corresponding explanation annotation data.

At this moment, described＜Auto Play〉in display speed, because follow the setting of [AUTO] mode in (step TP) that deals with at described guidance system, the automatic input that corresponding Auto Speed in the selection of teacher's side sets the key data of the speed that automatically performs that set, when correspondence automatically performs among the storer 19G is updated demonstration, so can carry out the demonstration that automatically performs of the speed consistent with the proficiency of student's side.

Then, by with described＜Auto Play when the chart following function of automatic input of corresponding key data finished, in the occasion that continues next key guide data of registration, order showed that the key of corresponding continuation instructs picture Gn.

Thus, even the student does not for example extremely understand the method for operating of chart function calculator 10B, the problem of the figure table function that also can be very simply proposes for the teacher is carried out the key operation input in that certain part is actual on one side, in certain part automatic input shown on one side, learn.

E-Activity in following this Figure 14 carries out the key data of the key operation policy paper of expression in the operation show state (its three) of handling (striped is carried out and handled), for example shown in Figure 14 (A '), for the guidance system under correspondence described [1 KEY] mode deals with＜Manual Play〉input that make, that register in corresponding note input store (Manual) 19E of 1 key of striped registration storer 19S shows each key data of the 3 key steps of for example being made up of [OPTN] [F4] [F2] of differentiation function.

Handle (step U4) by making to start to carry out to instruct, shown in Figure 14 (A), be presented at the key guide data [OPTN] that instructs display key step " 001 " in the GK of key range, show that in comment field N its first key that explains orally annotation data " TO INPUT X/DX PRESS[OPTN] " instructs picture G11 simultaneously.

When abideing by when this first key instructs each guide data among the picture G11 by student's operation " OPTN " key 12e, shown in Figure 14 (B), be presented at the key guide data [F4] that instructs display key step " 002 " in the GK of key range, show that in comment field N its second key that explains orally annotation data " INPUT[F4] " instructs picture G12 simultaneously.

When abideing by when this second key instructs each guide data operation " F4 " key among the picture G12 to select [CALC] button, shown in Figure 14 (C), be presented at the key guide data [F2] that instructs display key step " 003 " in the GK of key range, simultaneously, be presented at and show that its triple bond that explains orally annotation data " INPUT[F2] " instructs picture G13 in the comment field N.

Then, when abideing by when this triple bond instructs each guide data operation " F2 " key among the picture G13 to select [d/dx] button, the input picture Ga that shows such differentiation function formula shown in Figure 14 (D), each cursor C1, C2 of the input of coefficient and constant urged in demonstration.

Even the student does not for example extremely understand the method for operating of this chart function calculator 10B thus, the differentiation function formula that also can be very simply goes out for the teacher is actual on one side carries out the key operation input, on one side study.

Therefore, e-Activity function according to first example of the chart function calculator 10 by described structure, about being used for the teacher student is made the key operation process of execution as the function performance of problem, at corresponding [1 KEY] mode＜Manual Play〉or [n KEY] mode＜Manual Play the occasion of making its key operation policy paper of registration, can be in student's side while showing that its key of the actual input operation of key guide data of confirming its each key learns, in addition, at corresponding [Auto] mode＜AutoPlay〉occasion of making its key operation policy paper of registration, on one side student's side on one side order show that the key guide data of confirming its each key makes and import its key automatically and watch the demonstration of execution to learn.

Then, at combination and described [1 KEY] mode＜Manual Play〉or [n KEY] mode＜ManualPlay corresponding key operation policy paper and with described [Auto] mode＜Auto Play the occasion registered of corresponding policy paper making, can be in student's side in certain part while showing and confirm that its key of the actual input operation of key guide data of its each key learns, while can show and confirm its guide data and make in certain part in addition and import its key automatically and watch the demonstration of execution to learn.

Thus, the corresponding various settings such as interior perhaps its association's stage with problem can be easily carried out, the study of the higher function calculation of educational effect can be carried out.

In addition, this coordinate range (x min, x max, y min, y max), by being split into each demonstration of X-direction in liquid crystal display part (N * M display mode) 13 and Y direction count (rate respectively), determine the coordinate of each display dot, control diagram draw processing.

In addition, among the filename content text storer 19d that when carrying out described e-Activity mode, uses, the text T (with reference to Figure 17 (A) e-Activity picture Q) of the filename F of the e-Activity file made arbitrarily by education side user (teacher) of storage and learning content explanation thereof etc. for example.

In chart manoeuvre start button storer 19e, input and storage are used for the title explanation of souvenir in chart manoeuvre usefulness start button [GRPH-E] Be that shows at described e-Activity picture Q etc.This chart manoeuvre start button [GRPH-E] Be, when the chart manoeuvre problem of carrying out souvenir in the learning content comment (T) of described e-Activity picture Q (with reference to Figure 17 (A)) (striped carry out handle), manual operation by student's side user (student) oneself starts graph mode, selected operation when the pictorialization of the functional expression of having given is drawn demonstration etc.

Answer among the start button storer 19f at chart, input and storage are used for the title explanation of souvenir in the chart that shows at e-Activity picture Q is answered with start button [GRPH] Ba etc.This chart is answered with start button [GRPH] Ba, when the chart manoeuvre problem of carrying out souvenir in the learning content comment (T) of described e-Activity picture Q (with reference to Figure 17 (A)) (striped carry out handle), for example make the typical pictorialization that automatically performs, confirms the functional expression given draw action selected operation when learning.

In chart fill order storer 19g, be used to make the typical pictorialization that automatically performs the described functional expression of having given to draw the key input command of action, the key operation process of following actual pictorialization display action as being imported by operations such as teachers in its pattern register (striped registration process) in advance is stored registration.

Set among the tag memory 19h at final picture, in the striped registration process of the typical pictorialization display action of key operation process follow to(for) described chart fill order 19g storage, pictorialization display action for the key operation process of following this to be registered, the operation that the corresponding described chart of storage setting is answered with start button [GRPH] Ba only shows its final pictorialization picture, still also shows the sign of the process picture of each key operation in proper order.

In addition, in pointer coordinate storer 19i, detect, storage for example the position coordinates of the pointer P on the chart of drawing demonstration in the chart display frame (X, Y).

In chart data storer 19j, the corresponding chart data of drawing output usefulness of wanting the functional expression generation of pictorialization is stored as enclosing corresponding data bitmap with the apparent typical case of the chart on described liquid crystal display part 13.

In the 19k of workspace, the data of the control and treatment of exercises mode by control part (CPU) 11 input and output are followed in interim storage.

The following describes e-Activity function according to second example of the chart function calculator 10 of said structure.

In the choice menus picture of the exercises mode that the operation input of " MENU " key 12c in corresponding keys input part 12 shows on display part 13, after the e-Activity mode that the study of selecting to determine to carry out the figure table function is handled, when starting when carrying out the striped registration process (with reference to Figure 16) of registration of the manoeuvre problem (problem) of resolving for the pictorialization functional expression for learner (student), the new e-Activity picture Q (with reference to Figure 17 (A)) that shows the state of the content of not importing projects, at first, show the message of urging import file name F.

Here, for example when corresponding user's operation, during the F of filename arbitrarily " ABC " of the manoeuvre problem of this less important registration of input demonstration (step S1), then become the text input state of manoeuvre (study) content of figure table function as educator (teacher).Then, text T as manoeuvre (study) content, for example when input shows " EX1＞Answer the intersection ", follow this, the filename F " ABC " of described input and content text T " EX1＞Answer the intersection ", storage (step S2) among the filename content text 19d in RAM19.

In new e-Activity picture Q, preestablish the displayed map performance and commonly use start button [GRPH-E] Be and answer start button [GRPH] Ba, the former is used in reference to the operation input that is shown in accordance with learner (student) oneself and makes the processing of startup chart biological function explore answer as the manoeuvre content of the figure table function of described text T input demonstration, and the latter is used to make automatic startup figure table function to make and shows that typically parsing is answered.

Here, when described chart manoeuvre is specified in the respective user operation with start button [GRPH-E] Be (step S3), the button frame that shows the state of not importing title explanation arbitrarily be used to represent its content, become and this chart manoeuvre with the input waiting status (step S4) of the corresponding explanation of title arbitrarily of start button [GRPH-E] Be.

Then, in the button frame of described chart manoeuvre with start button [GRPH-E] Be, as its input of title explanation arbitrarily, for example show " Use this strip ", storage back (step S5) among the chart manoeuvre start button storer 19e in RAM 19, then, when the respective user operation specifies described chart to answer with start button [GRPH] Ba (step S6), show to be used to represent that the title arbitrarily of its content is illustrated as the not button frame of the state of input, become with this chart and answer the input waiting status (step S7) that illustrates with the corresponding title arbitrarily of start button [GRPH] Ba.

Then, in described chart is answered the button frame of using start button [GRPH] Ba, as its title explanation arbitrarily, for example input is shown as " Answer Example ", chart in RAM 19 is answered with storage back (step S8) among the start button storer 19e, the required purpose show state of e-Activity picture Q that become input such shown in Figure 17 (A).

Like this, projects at e-Activity picture Q are transfused under the state that shows generation, when operation input " EXE " key 12f (step S9), start the registration function of figure tabular form, shown in Figure 17 (B), displayed map table function input picture K becomes the input waiting status (step S10) that corresponding this e-Activity picture Q should become the functional expression of manoeuvre problem.

In this figure table function input picture K, when the functional expression that should become the manoeuvre problem for example as " Y1=X ²-1 " " Y2=2X-2 " is transfused to when showing (step S11); the functional expression of this input and described chart manoeuvre are answered to be mapped with start button [GRPH] Ba with start button [GRPH-E] Be and chart and stored (step S12) among the input type storer 19b among RAM 19; shown in Figure 17 (C); e-Activity picture Q of this generation of demonstration again; simultaneously, shows as the manoeuvre formula J corresponding with the project of the manoeuvre content (T) of this figure table function.

Then, in 6 function button B1～B6 that the lower end along described e-Activity picture Q shows,, shown in Figure 17 (D), show that the registration of typical operation begins message M by the operation input function key " F3 " corresponding with the position of " AUTO " button B3.

In view of the above, shown in Figure 18 (E), when operation " EXE " key 12e, read the functional expression " Y1=X that will become the manoeuvre problem that the described chart manoeuvre of the e-Activity picture Q in making with this is mapped and stores with start button [GRPH] Ba with start button [GRPH-E] Be and chart answer in input type storer 19b ²-1 " " Y2=2X-2 " draws demonstration (step S13) as each corresponding chart data Y1, Y2 on chart picture G.

Like this, showing and function formula " Y1=X as the manoeuvre problem ²-1 " under the state of the chart picture G that " Y2=2X-2 " is corresponding; when specify (step S14) when finding the solution function (G-Solve) as this figure table function exectorial by the operation input of function key " F5 ", this appointed chart of storage registration conduct is found the solution the key data (step S15) of the exectorial function key " F5 " of function (G-Solve) in chart fill order storer 19g.

So, shown in Figure 18 (F), arrange the various menu button Bsol (step S16) that find the solution function that demonstration is used to select the given chart function along the lower end of chart picture G.

Here, function as the intersection point of chart Y1 among the chart picture G that finds the solution in the demonstration and Y2, " ISCT (Calculate Intersection point) " button B5 in described menu button Bsol existence, (step S17 (No) → S14), the key data of finding the solution the exectorial utility key " F5 " of function (ISCT) as this appointed intersection point is added storage registration (step S15) in described chart fill order storer 19g when the utility key " F5 " that passes through correspondence is designated.

So, shown in Figure 18 (G), abide by consistent the putting of coordinate of the data of chart Y1, Y2 and resolve this chart Y1, the intersection point P of Y2 that is presented at the last demonstration of described chart picture G, simultaneously, show the intersection point alignment chart picture Gsol (step S16) that finds the solution the XY coordinate [X=1] [Y=0] that has shown this intersection point P.

Like this, from functional expression " Y1=X as described manoeuvre problem ²-1 " demonstration of the chart picture G that " Y2=2X-2 " is corresponding carry out in the chart function action after " EXE " each command key " F5 " (G-solve) → " F5 " input process (ISCT) be registered under the state among the described chart fill order storer 19g; when " SHIFT "+" → " key of the end of the exectorial registration process of operation input this a series of chart of expression (step S17); after this answer when making the typical pictorialization that automatically performs described functional expression draw action with start button [GRPH] Ba by described chart when this manoeuvre problem of execution; select the setting picture when showing not shown execution, this picture is used for selecting in advance whether only typical its final chart picture (step S18) of demonstration of setting.

Then, when this is carried out, select to set in the picture,, set tag memory 19h for the final picture in the RAM 19 and set sign " 1 " (step S19) in the occasion (step S18 (Yes)) of selecting to set " only the typical case shows final chart picture ".

So, shown in Figure 18 (H), answer to be mapped with chart and show that souvenir represents that registered pictorialization draws the e-Activity picture Q of Auto icon " A " I that automatically performs order of action, judge whether to operate " EXIT " key (step S20) of having imported the end that expression imports for the file of this this e-Activity picture Q with start button [GRPH] Ba.

Then, when operation input described " EXIT " key is judged for this file end of input of e-Activity picture Q (step S20 (Yes)), the file content of in the striped registration storer 19S that forms by described filename content text memory cell 19d, chart manoeuvre start button storer 19e, chart answer start button storer 19f, chart fill order storer 19g, final picture setting tag memory 19h, registering, constant in memory card (exterior storage medium) 16, preserve (the step S21) of former state.

Like this, generate the memory card (exterior storage medium) 16 that registration has the e-Activity file,, taken out, be installed among learner's (student) the chart function calculator 10B and use by chart function calculator 10A from teacher's side as above-mentioned shown in Figure 1.

Perhaps, the content of the e-Activity file of registering in described striped registration storer 19S, as above-mentioned shown in Figure 2, the chart function calculator 10B that is sent to student's side by USB cable 18c and external personal computer PC communication uses.

In learner's (student) chart function calculator 10B, after the e-Activity mode that the study of selecting to determine to carry out the figure table function is handled, when the striped that carries out the execution of this manoeuvre problem when startup carry out to be handled (with reference to Figure 19), read the e-Activity file (for example " ABC ") (steps A 1) of user's appointment from the various files of registration memory card (exterior storage medium) 16, the chart that shows such Auto icon " A " I shown in Figure 20 (A) that had souvenir on liquid crystal display part 13 is answered the e-Activity picture Q (steps A 2) with start button [GRPH] Ba.

In this e-Activity picture Q, when in order to learn and the text T " EX1＞Answer the intersection " of its manoeuvre (study) content manoeuvre problem functional expression " Y1=X of souvenir together ²-1 " " Y2=2X-2 " (J) selects to scheme to perform to use start button [GRPH-E] Be or chart answer to use start button [GRPH] Ba to operate when importing " EXE " key 12f (steps A 3 (Yes)); at first; chart is drawn and is activated; shown in Figure 20 (B), draw demonstration and this each manoeuvre problem functional expression " Y1=X ²-1 " " Y2=2X-2 " corresponding chart data Y1, Y2 (steps A 4).

So, in described e-Activity picture Q (with reference to Figure 20 (A)), judgement is that operation has been imported chart that the typical parsing that is used for showing automatically described manoeuvre problem functional expression answers and answered with start button [GRPH] Ba (steps A 5 (Yes)), or imported in accordance with learner's (student) oneself operation input operation and to have indicated the figure that is used to make the processing of resolving answer to perform to use start button [GRPH-E] Be (steps A 5 (No)).

Here, for example imported figure that indication is used to make the processing of resolving answer in accordance with learner's (student) oneself operation input operation and performed occasion (steps A 5 (No)) being judged as, just become the common chart function action state that is undertaken by user's (student) oneself manual operation with start button [GRPH-E] Be.

That is, wanting to find the solution and showing the intersection point P etc. of described chart data Y1, Y2, the occasion of its unique point, abide by the manual operation corresponding and carry out corresponding finding the solution and move and show with this unique point that will find the solution.

That is, wanting to abide by the occasion that the intersection point P that shows chart data Y 1, Y2 is found the solution in manual operation, at first, find the solution function (G-Solve) by specifying, arrange the various menu button Bsol that find the solution function that demonstration is used to select the given chart function along the lower end of chart picture G by the operation input of function key " F5 ".Then, the operation input of the function key " F5 " by " ISCT (Calculate Intersection point) " button B5 correspondence of existing in described menu button Bsol specifies chart Y1 in showing and the intersection point of Y2 to find the solution function, thus, abide by consistent the putting of coordinate of the data of this chart Y1 and Y2 and resolve its intersection point of demonstration P, and show the intersection point alignment chart picture Gsol (with reference to Figure 18 (E)～(G)) of the XY coordinate [X=1] [Y=0] of this intersection point P.

On the other hand, with the manoeuvre problem functional expression " Y1=X of described Figure 20 (B) expression ²-1 " under the show state of chart Y1, the Y2 that " Y2=2X-2 " is corresponding; imported to be used to make and show that automatically its typical chart of answering of resolving answers occasion (steps A 5 (Yes)) with start button [GRPH] Ba being judged as operation; the final picture in the e-Activity file of user's appointment of reading in described steps A 1 is set in the flag data (19h), judges whether to be provided with the sign " 1 " (steps A 6) of expression " the only final chart picture of typical case's demonstration ".

Here, be judged as the sign " 1 " that expression " the only final chart picture of typical case's demonstration " is not set, promptly comprise the process that typical parsing answers and be the occasion (steps A 6 (No)) that makes the action set condition of automatic demonstration, be stored registration as chart fill order data (19g) in the e-Activity file of this user's appointment, from the demonstration of chart picture G carry out in the chart function action after " EXE " each command key " F5 " (G-solve) → " F5 " key data (ISCT) called over, shown in Figure 20 (C) → (D), carry out and (G-solve) → " F5 " (ISCT) corresponding chart function action (step 7 of this command key " F5 ", A8).

That is in this occasion, the corresponding key data of command key " F5 " is for the first time read, shown in Figure 20 (C), the various menu button Bsol that find the solution function that demonstration is used to select the given chart function are arranged in lower end along chart picture G, and the corresponding key data of command key " F5 " is for the second time read, shown in Figure 20 (D), abide by chart Y1, consistent the putting of the coordinate of the data of Y2 resolved this chart Y1 that is presented at the last demonstration that shows of described chart picture G, the intersection point P of Y2, simultaneously, the intersection point alignment chart picture Gsol that shows the XY coordinate [X=1] [Y=0] of having found the solution this intersection point P.

Thus, user (student) only answers with start button [GRPH] Ba operation " EXE " key 12f by the chart of selecting to be positioned on the described e-Activity picture Q, just can be by the figure list processing (LISP) action of the reality among the oneself chart function calculator 10B, veritably make order automatically demonstration from this manoeuvre problem functional expression " Y1=X ²-1 " " Y2=2X-2 " (J) corresponding chart Y1, Y2 draw picture to the typical parsing answer picture of the intersection point alignment chart picture Gsol that resolves intersecting point coordinate P and confirm.

On the other hand, final picture in the e-Activity file of user's appointment that described steps A 1 is read is set in the flag data (19h), in the occasion (steps A 6 (Yes)) that is judged as the sign " 1 " that is provided with expression " only the typical case shows final chart picture ", be stored registration as chart fill order data (19g) in the e-Activity file of this user's appointment, each command key " F5 " in the chart function action (G-solve) → " F5 " key data (ISCT) is called over, carry out in inside and (G-solve) → " F5 " (ISCT) the corresponding chart function action of this each command key " F5 ", but externally, as Figure 21 (A) (B) shown in, the demonstration of message M1 in moving from the initial show state of e-Activity picture Q is omitted from chart Y1, update displayed (the steps A 9 of drawing the chart picture G that follows its intersection point solution procedure of Y2, A10).

Then, when reading (steps A 10 (Yes)) when being stored (ISCT) key data of command key registration, last " F5 " as described chart fill order data (19g), shown in Figure 21 (C), abide by consistent the putting of coordinate of the data of chart Y1 and Y2 and resolve demonstration and described manoeuvre problem functional expression " Y1=X ²-1 " " Y2=2X-2 " (J) intersection point P of corresponding chart Y1, Y2 simultaneously, directly shows the intersection point alignment chart picture Gsol (steps A 11) that finds the solution the XY coordinate [X=1] [Y=0] that shows this intersection point P as final display result.

Therefore, e-Activity function according to second example of the chart function calculator 10 of described structure, make in the striped registration process of the e-Activity picture Q that is presented in the e-Activity mode, the teacher for the student draw show with should be as the functional expression " Y1=X of problem ²-1 " behind the chart picture G of chart Y1, the Y2 that " Y2=2X-2 " is corresponding; when by " F5 " (G-solve) key start the function of finding the solution of characteristic chart point; simultaneously and then by " F5 " (ISCT) during the finding the solution order and showing intersection point alignment chart picture Gsol of key input intersecting point coordinate P, be used for each key data " F5 " of finding the solution order of after drawing of this chart Y1, Y2 shows, importing (G-solve) → " F5 " (ISCT) in proper order with described e-Activity picture Q on the chart answer be mapped with start button [GRPH] Ba and be carried out registration.

Then, carry out in the processing at the striped that makes the e-Activity picture Q after showing described striped registration process, when the chart on selecting this e-Activity picture of execution Q is answered with start button [GRPH] Ba, drawing demonstration and the manoeuvre problem functional expression " Y1=X that is just showing ²-1 " " Y2=2X-2 " is (J) behind the chart picture G of corresponding chart Y1, Y2; abide by with described chart and answer be mapped " F5 " (G-solve) (ISCT) each key data of key of key+" F5 " of registration with start button [GRPH] Ba; sequence starting characteristic chart point find the solution function, carry out simultaneously that finding the solution of intersecting point coordinate P handled and automatic demonstration intersection point alignment chart picture Gsol.

In this occasion, select during execution in described striped registration process to set in the picture, in the occasion of selecting to have set " only the typical case shows final chart picture ", carry out in the processing at described striped, because only directly automatically show to follow to abide by to have with described chart and answer (G-solve) key+" F5 " (ISCT) in each key data of key with " F5 " of the corresponding related registration of start button [GRPH] Ba in registration, the intersection point alignment chart picture Gsol that finds the solution processing of last key data " F5 " intersecting point coordinate P (ISCT) (final picture), so, can want a series of processes that teaching figure table function resolves or only want its net result of teaching quickly easily to select and registered its setting content for learner (student) correspondence as educator's user (teacher).

Thus, the various settings in the content of corresponding problem or its association's stage etc. can be easily carried out, the study of the higher figure table function of educational effect can be carried out.

(other examples)

In addition, in above-mentioned second example, with regard to its corresponding manoeuvre problem functional expression about drawing the chart data Y1 of demonstration, the parsing of Y2, illustrated by the function (G-solve) of finding the solution of its characteristic chart point and found the solution the situation that intersecting point coordinate P makes demonstration intersection point alignment chart picture, but in making the situation of finding the solution the unique point that shows such chart, much less be not limited to described intersecting point coordinate P, also can or make to show the chart picture of having found the solution the minimum coordinate MIN of very big coordinate MAX, perhaps find the solution various unique points by pointers track demonstration (chart tracking) on one side the track of chart makes on one side.

Generally speaking, as long as only the content of the command operation of the typical resolving of following the figure table function (for example key input process) is carried out storing registration after the non-setting/setting of described " only typical case show final chart picture ", and the content of abideing by the command operation of this registration makes the chart function action, like this, just can show described typical resolving in proper order or only show final picture.

In addition, the method that each of the chart function calculator of putting down in writing in described each example 10 handled, that is the method in following processing: in the e-Activity mode of first example of promptly in the process flow diagram of Fig. 5, representing, generate the e-Activity policy paper and be used for relatedly making registration follow the method that make processing (striped registration process) as the e-Activity of the key operation process of the function calculation of problem, follow the guidance system of described first example of representing in the operation procedure for displaying of the process flow diagram of Fig. 6 and Fig. 7～Figure 10 method in dealing with the striped button is corresponding; The e-Activity that is used for abideing by described first example that the operation procedure for displaying of process flow diagram by Figure 11 and Figure 12～Figure 14 represents makes and handles e-Activity policy paper that (striped registration process) generate and the e-Activity of the problem of execution graph table function is carried out handle method in (striped is carried out and handled), second example of the flowcharting by Figure 16 generate the e-Activity file and with chart answer with start button [GRPH] Ba corresponding related be used for making registering follow typical pictorialization to draw the method for striped registration process of the key operation process of action, the e-Activity file that generates with the striped registration process of described second example that is used for abideing by the flowcharting by Figure 19 makes the striped of the manoeuvre problem of execution graph table function carry out method in handling etc., any one is all as the program that computing machine is carried out, can be at memory card (ROM card, RAM card etc.), disk (floppy disk, hard disk etc.), CD (CD---ROM, DVD etc.), issue after the storage in the exterior storage mediums such as semiconductor memory 16.Then, computing machine writes reading part 17 by storage medium and reads in program stored in this exterior storage medium 16, by this programmed control of reading in action, be implemented in the e-Activity function of the demonstration of following the figure table function that has illustrated in above-mentioned each example thus, can carry out same processing based on said method.
