Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electronic learning machine suitable for learning arithmetic, and in particular, if you start practice questions after inputting numerical data, uniform practice questions will be asked according to the numerical data. Furthermore, if the practice questions are started without inputting numerical data, non-uniform practice questions will be asked, thereby providing an electronic learning machine that is capable of asking unified practice questions.

In recent years, with the development of electronic technology, a large number of various electronic learning machines have been commercialized, one of which is an arithmetic problem practice machine. These conventional arithmetic problem practice machines generally first generate random numbers, and then use the generated random numbers to create arithmetic practice problems.

Therefore, even if the same model of problem practice machine is used, the content of the questions asked varies widely, so there is a need for each student to study the same set of questions in a cram school or class. In some cases, no matter how good the quality of the question practice machine, it has the drawback of not being usable. Furthermore, 2
~ Even when three people compete to see how many questions they can answer, the questions on the problem practice machine are different for each person, so some people may be given comparatively easy questions one after another, and some people may be asked relatively easy questions one after another. Because only difficult questions were asked one after another, it became impossible to simply judge who did well based on the displayed score. This not only made it impossible to compete in a game-like manner, but also discouraged customers from using the question practice machines, causing them to lose customers who had the potential to make large transactions.

The purpose of the present invention is to eliminate the above-mentioned drawbacks, and when you want to practice using standardized practice questions, all you have to do is input the predetermined numerical data and then start the practice questions. To provide an electronic learning machine whose functions can be improved without adding any electrical mechanical parts or increasing manufacturing costs.

Hereinafter, the present invention will be explained in detail with reference to the drawings.

FIG. 1 shows an example of the configuration of the electronic learning machine of the present invention, where 1 is a display, 2 is a decoder driver,
3 is a display register, 4 is an arithmetic processing circuit, and 5 is a
ROM (read only memory), 6 is RAM (random access memory), and 7 is a keyboard. The arithmetic processing circuit 4 uses a program for practicing arithmetic problems built in the ROM 5 in advance according to the contents of various signals supplied from the keyboard 7.
6 to perform predetermined arithmetic processing on data etc.
The display data obtained as a result is sent to the display register 3, and the display device 1 is driven via the decoder driver 2 based on the sent data.

Next, the operation of the electronic learning machine shown in FIG. 1 will be explained with reference to the flowchart shown in FIG.

Here, 10 is a display step for issuing a command to display display data. In addition, 11 is a key determination step that determines whether or not a key on the keyboard 7 has been pressed.If there is no key input, a negative determination (NO) is made, and in step 28, the time counter used as the initial value of the random number is set to "+1". ”After addition, return to display step 10. When there is a key input, the process proceeds to determination step 12, where it is determined whether the input key is a numeric key or not, and if it is a numeric key, an affirmative determination (YES) is made.
Then, in the next determination step 13, it is determined whether or not the problem processing has started by checking whether a start flag, which will be described later, is set. If the determination is negative, in step 14 the above-mentioned numeric key is determined to be initial value data set for initial value setting, initial value set processing is performed, and the process returns to display step 10.

Next, when the question start key is input, a negative judgment is made in the number determination step 12, and the start flag indicating that the practice question has started is pressed.
After setting in step 19, it is determined in determination step 20 whether or not initial values for creating unified questions have been set. If the determination is negative, the process advances to step 21, and the time counter data (count value) created in step 28 is set as an initial value for random number generation. On the other hand, if the determination is affirmative, processing is performed in step 22 to set the input data as an initial value for random number generation. Thereafter, it is determined in step 23 whether or not a predetermined number of questions have been asked, and if the determination is negative, the count value of the question counter is incremented by 1 in the next step 24, and in the following step 25, the count value of the question counter is incremented by 1. Generate random numbers based on the set initial value. Next, in step 26, after creating a problem using the generated random numbers, the display step
Return to step 10, display the problem on the display, and start problem processing.

Next, when the corresponding replacement key is input as an answer to the displayed question, a positive determination is made in determination step 12, and since the start flag has already been set in this case, the next determination step 13 is also determined to be affirmative. Therefore, it is determined in step 15 whether or not the numeric keys are correct as input answers. If the answer is correct, it will be judged as affirmative and the next step will be taken.
In step 17, it is displayed that the answer is correct, and the points are added. If it is an error, a negative determination is made and the correct answer is displayed on the display 1 in step 16. Then,
In a timer step 18, a timer for displaying these displays for a certain period of time determines whether a predetermined period of time has elapsed or not, and waits until an affirmative determination is made.

Thereafter, in order to determine whether or not to ask the next question, in the same manner as described above, in a determination step 23, it is determined whether a certain number of practice questions have been asked based on the count value of the question counter. If the judgment is negative, the question counter is incremented by one in step 24, a random number is generated in step 25, a question is created in step 26 based on the random number, and the process returns to display step 10 to display the question. If it is determined in the judgment step 23 that a certain number of questions have been asked, the process jumps to step 27, resets the start flag, and performs processing to display the score, then returns to display step 10 and displays the score. This completes one practice problem process.

As explained above, the present invention has the advantage that standardized practice questions can be asked without the need to add electrical mechanical parts such as switches, which cause an increase in manufacturing costs. In addition, according to the present invention, since unified practice questions can be asked by selection, it is a useful electronic learning method that can be used in an extremely wide range of uses, from personal study to group study such as cram schools and school classes. You can get a chance.
