Description

[Detailed explanation of the idea] This invention relates to a calculation training machine.

Conventionally, methods have been proposed that output a calculation problem, input the answer, and output the correct/incorrect information, or input both the calculation problem and the answer, and output only the correct/incorrect information.

However, these conventional calculation practice machines can be used in cases where you do not know how to obtain the answer, or where you have made a mistake or cannot identify the cause.
If only the correct and incorrect output is output, it ends up being a kind of entertainment game,
A sufficient educational effect could not be expected.

This invention is a calculation practice machine that outputs a calculation problem, inputs an answer, and outputs the correct/incorrect answer.By determining that an incorrect answer has been input, When the person instructs by key operation etc.
Or ■ By determining that no answer has been input within a certain period of time after outputting a calculation problem, instruct the format of the output calculation problem to be changed, change it to a format that is easier to solve, and ask for the answer at any time. The aim is to give the user a chance to input data, thereby increasing the educational effectiveness of the calculation practice machine.

For example, when a problem of 3+8= is given, the form of the problem is sequentially changed as shown below, and the player is given a chance to find and input the answer.

(4) Output of calculation problem 3+8 (B) Swap operand and operand 8+3-
(Separate the 0 arithmetic number into three terms and make the sum of the two terms equal to 10. 8+2+1=(4) to (B), (
To change the output from B) to 0, refer to (■) above.

This is possible by determining either (1) or (2).

In this way, even if 3+8- cannot be found in the form as it is, if it can be found in the form (B) or (C), by repeatedly practicing the same type of problem, (B) or even (4) ), and the correct answer is required, which can be expected to have an educational effect.

An embodiment of the present invention will be described below with reference to the drawings.

Reference numeral 1 denotes a device that controls the type of problem to be output (designation of addition, subtraction, multiplication, division, number of digits, presence or absence of carry, etc.), and is controlled by the operator's key and switch operations.

2 is a device that generates a problem based on the designation of the problem control device 1;

Reference numeral 3 denotes a register for storing questions, and the questions are displayed on a display device (not shown).

4 is an input device for answers, 5 is a numerical storage register for storing answers, and 6 is a match detection circuit. By pressing the correct/incorrect judgment key 7, the match detection circuit 6 reads the questions stored in the question storage register 3. The answer is determined and a match with the answer input by the operator stored in the numerical storage register 5 is detected.

8 is a correct answer display circuit.

Reference numeral 9 denotes a problem form changer which forms a loop with the problem storage register 3, changes the form in response to the same problem, and stores the changed problem in the problem storage register 3.

10 is a timer that is set when the problem generation from the problem generator 2 or the problem change from the problem form changer 9 is completed and outputs after a certain period of time; 11 is a form change key;
These outputs together with the outputs of the match detection circuit 6 control the problem form changer 9.

For example, if the control circuit 1 in question specifies addition, 2 digits + 1 digit, and carry, the problem generator 2 will be 17+8
A problem such as - is generated and stored in the problem storage register 3, and this problem is displayed on the display device.

When the problem generation is completed, the timer 10 is set, but if the operator inputs a numerical value considered to be the correct answer using the answer input device 4 and presses the correctness determination key 7 within a certain period of time, the match detection circuit 6 The answer to the question stored in the question storage register 3 is obtained by searching for the answer to the question stored in the question storage register 3, and a match with the answer input by the operator is detected.

If they match, the correct answer display circuit 6 outputs an output indicating the correct answer.

When they do not match, the mismatch output is supplied to the problem form changer 9, and 17+8 = a form that makes the problem easier to solve;
For example, the operand and the operand are changed to 8+17=, and the result is stored in the problem storage register 3.

Even when the form change key 11 is pressed without knowing the answer, or after the fixed time of the timer 10 has elapsed, the key output or timer output is supplied to the problem form changer 9, respectively.
The problem is forcibly or automatically changed into an easy-to-solve format and stored in the problem storage register 3.

Next, when the answers do not match again, the form change key 11
When is pressed or after a certain period of time set by the timer 10 has elapsed, the format is changed to a format that is easier to solve, for example, 17+3+5-, which takes carry into consideration.

This can be repeated as many times as necessary depending on the configuration of the problem format converter 9 and the like.

As described above, the present invention is an apparatus that outputs a calculation problem, has the answer manually, and outputs the correctness of the answer, and is provided with a means for changing the form of the calculation problem and outputting it, and a means for instructing the change of the form. However, if the answer is incorrect, if you do not know how to find the answer, or if you cannot find the answer within a certain time, etc., you will be instructed to change the form of the calculation problem to make it easier to solve. This allows the user to have the opportunity to ask for and input answers at any time, improving the educational effectiveness of the calculation practice machine.
