Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to an interactive learning system useful for learning accounting journal entries, etc. The present invention relates to an interactive learning system that is useful for learning journal entries in accounting, etc. Regarding the question processing method that randomly changes each time.

[Conventional technology]

One of the learning systems for accounting is to use a display device to present practical transaction examples in an interactive format for the purpose of acquiring knowledge of account subjects, have the learner enter the journal entry results, and check the results. There is something to be evaluated as r-'7.

FIG. 2 shows an example of such an accounting learning system. In the figure, 21 is a learning processing device, 22
23 is a display device, 24 is a transaction example display column, 25 is an answer display column, 26 is a question status display column,
27 is a menu and message display field.

The learning processing device 21 sequentially presents a certain number of transaction examples according to a preset learning course.

The learner reads the transaction description in the transaction example display field 24 displayed on the display device 23, performs journal entry, inputs the results from the key input device 22, and answers.

This answer is displayed in the answer display field 25. For the illustrated transaction example, the correct answer is:

(Debit amount) (Course name) (Credit amount) 3.
000,000 Current account securities 2,531,250 Gains on securities sales 468,750 Out of the number of questions, how many questions have been answered and how many questions remain are displayed in the question status display column 26.

The menu and message display field 27 displays a menu for advancing the learning, messages regarding correctness of answer results, and other messages.

By the way, in some systems, about 200 transaction examples are prepared in advance for questions, and they are presented in a predetermined order.

On the other hand, when a learner continues to practice journalizing using a learning system, if the question content is the same every time, the learning becomes monotonous and the learning effect decreases. Therefore, in order to prevent this problem, it is desirable to change the content of the questions each time.

[Problem that the invention seeks to solve]

One way to change the content of questions is to use random numbers to change numerical values such as amounts, quantities, and ratios used in questions each time. For example, ``We sell a complete set of word processors for 480,000 yen at a 13% discount.
The payment was received by check. ” in the transaction description,
Sometimes 6 years old, [Word processor set 398,0
00 yen at a 13% discount, and received the payment in the form of a check. ] It changes things like this.

If there is no change in the amount, record the explanation as it is in the file, ``We sold a set of word processors for 480,000 yen at a 13% discount, and received the payment in the form of a check.'' All you have to do is read it out and display it. Also, it would be easy if all the numbers in the sentence were uniformly multiplied by a random number, but if you multiply a number like 113% of this example sentence by a random number, the reality of the problem becomes less realistic, or there is a difference between the previous and subsequent transactions. There is a risk that a situation may arise where you end up paying more than the accounts payable, and the logic of the transaction is lost.

[Means for solving problems]

As mentioned above, many of the numerical values used in the problems have different characteristics and cannot be handled in a regular manner. Therefore, in the present invention, all the numerical values in the problems are expressed as variables and stored in a file, and on the other hand, Defining formulas for variables and arithmetic formulas that give answers are created and managed separately, and numerical values and correct answer values in questions are generated using initial values and random numbers each time the system is used. This makes it possible to set realistic numerical values for each variable each time, and also facilitates consistency by sharing variables between transactions.

Accordingly, the configuration of the present invention is such that, in an interactive learning system, a problem table means stores a plurality of problems expressed using variables, and an arithmetic expression for finding a solution to the problem using the variables is made to correspond to the problem. A plurality of arithmetic expression table means are stored, and a definition expression is stored that represents variables used for each of the above problems and definitions that give numerical values to each of the variables, and that directly or indirectly includes a random number as an element. a table means, a question control means for selecting and presenting questions one by one from the problem table means, a random number generation means, a variable and a definition formula to be used for the selected problem, extracted from the definition formula table means; Numerical determining means for determining the numerical value of each variable using the random numerical value output from the random number generating means, and a corresponding arithmetic expression from the arithmetic expression table means, and assigning the determined numerical value to the variable to determine the correct answer. and a correct answer calculation means for calculating the above, the numerical value obtained for each variable is substituted into the variable in the question, and the input answer is checked by comparing it with the correct answer. It is.

[Action of the invention]

The operation of the present invention will be explained by way of example when applied to an accounting learning system.

■Separately store transaction description text information and journal information.

■In the transaction description, changing numbers and numbers used to calculate the journal answer amount do not have actual numbers in the text, but are simply written as A, B, C in the order in which they appear. ,e
Express it as a variable of ct.

■On the other hand, as journal information, in addition to information for specifying account items (account code), information for calculating the amount of that item such as 'A B + J' and 'AR * 0.13'
An arithmetic expression in reverse Borland notation, such as kJ, is given. Here, the variable R represents a random number.

By doing this, it becomes possible to code as answer information the procedure for how the numerical values appearing in the explanatory text are used when calculating the amount of the account item.

■Also, for variables that are used only in the transaction description and are defined by calculations between other variables in the sentence, a definition formula such as 'C=AB+' is given.

(2) In this way, initial value definition formulas such as 'A=480000R*' are given only to variables that ultimately need to be quantified.

■When displaying a transaction explanation using a file prepared in advance in this way, first refer to the journal information, calculate the amount in question at that point taking into account random numbers, and then change the variables in the explanation. Embed and display in parts. At the same time, correct information on the journal entry results is generated according to the calculation formula and used to judge the learner's input.

The learner can view the menu displayed on the display device 3,
While looking at the questions, messages, etc., the user inputs necessary commands and answer data using the key human power device 4 to proceed with learning. The number and order of transactions that will be asked are predetermined.
The question is selected by the question control section 7 using the transaction number.

The display processing unit 5 sequentially reads transaction examples from the transaction question table 12 according to the selected transaction number by the question control unit 7 and outputs them to the display device 3. The question control unit 7 selects variables (A, B,
C1...) is replaced with the numerical value sent from the numerical value determining section 8.

The numerical determination unit 8 extracts the variable name and definition formula to be used from the definition formula table 14 according to the transaction number selected by the question control unit 7. In addition, the correct answer calculation unit 9 uses the calculation formula table 1
Extract the corresponding arithmetic expression from 3.

The calculation formula table 13 shows calculations based on the item code representing the account item of the journal entry result and the given variables and constants (initial values) necessary to calculate the journal amount for each transaction example in the transaction problem table 12. It stores the expressions.

The definition formula table 14 stores definition formulas for giving actual numerical values to variables used in each of the above calculation formulas, and the definition formulas include conversion formulas consisting of constants and random numbers, and variables. There is a relational expression. The latter variables are not variables that appear directly in the arithmetic expression, but are used as an intermediary. R in the figure represents a random number, and K represents a constant 1,000. If necessary, the range of change in numerical values due to random numbers is limited.

A random number generator 10 generates a random number R every time the learning system is used.
