Description

correlation of the number of questions and correct answers 5, the output of which is connected to the evaluation unit 6. The inputs of the evaluation unit of response 7 are connected to the outputs of the information presentation unit 1 and the logical unit 2. The inputs of the analog-digital converter 8 are connected to the outputs of the logic unit 2 and the unit the answer scores are 7, and the output is with the input of the cross-correlation block of the number of questions and the correct answers 5.

The student receives educational information through the information presentation block 1 and enters his answers using the information input block 3. From the information presentation block 1, the signal about the correct answer to the question is fed to the input of logic unit 2, and the signals about the complexity of the question or its diagnostic weight in the form of a binary code - on the installation inputs of the response connection block 7, where these signals are recorded directly in the form of the definite number of points, since the decoding of the code occurs due to the parallel input. When a response signal is received from the input unit 3, the logical response unit 2 evaluates the quality of the response. If the answer of the student completely coincides with the standard answer that the signals from the outputs of logic unit 2 are fed to the input of the display unit 4, which provides an indication of the control code, and the analog-digital converter 8, allowing the conversion of signals of the “weights of the correctly answered question coming from the output of the answer evaluation unit 7. From the output of the analog-digital converter 8, the signal enters the mutual correlation unit of the Kolnches: TWA questions and correct answers 5, which also receives a signal that the question is answered from a logic block. 2. On the basis of these signals, in the block of mutual correlation of the number of questions and correct answers 5, the current zone is determined by the CoPtrol, in this case, the work zone is Continue polling, and a signal is generated which, through logic block 2, enters the information presentation block 1 , providing the next dose of information. The block of mutual correlation of the number of questions and correct answers 5 is identical in structure to the same block of the main device, but instead of counting erroneous answers, it counts the number of conditional points for correct answers, and the current control zone is determined by the ratio of the number of conditional points for correct answers and numbers of questions. If the answer of the increasing part coincides with the reference answer partially, then in logic block 2 a signal is generated that characterizes the degree of discrepancy of the answer and is fed to the input of the answer evaluation block 7, where a certain number of points are subtracted, in accordance with the degree of discrepancy of the answer, from . The remaining number of conditional points “of the weight of the question from the output of the evaluation unit of response 7 is fed to the input of the analog-digital converter 8, and further work is done in a similar way. If the student gave a completely wrong answer, then he is allowed to re-think the task and give a new answer, however

but the signal from logical block 2 in the answer evaluation block 7 subtracts a certain number of conditional points, for an incorrect attempt, from the total weight of the question. If at the second attempt the students gave a moral answer, then the work is done in a similar way. The number of possible responses of a pa question is asked in logic block 2. When answering a pa question, the sigpal that the question is answered from logic unit 2 goes to

analog-to-digital converter 8 only once or at the correct, partially correct, or at the last attempt to answer. After the unit presents information for the next 1 task, the entire operation cycle of the device is completely repeated. At the same time, after each answer, the unit of mutual correlation between the number of questions and the correct answers 5, based on the ratio of the number of conditional points for the correct answers and the number of questions, determines the current control zone. As soon as the current control zone coincides with one of the specified rating zones, the number of questions and correct answers 5 is formed in the mutual correlation block 5.

signal that goes to logic

2, ensuring that control ceases, and

block of assessments 6, ensuring memorization and

indication of the assessment received.

Thus, the proposed device

It has enhanced functionality, since the correlation between the number of questions and correct answers is based on both the complexity of the questions and the degree of accuracy of the answers to the questions, which ultimately provides an increase in the effectiveness of training.
