Description

The invention relates to the field of computing and automation and can be used to control knowledge in schools in various disciplines.

A device containing a comparison unit is known, the inputs of which are connected to input and memory blocks, and the outputs are connected to the information output unit and the evaluation unit, and the Invalid responses limiter [1] ·

It is also known a device containing work consoles, a block for entering the question number and a block for entering the response, a teacher’s information board, a board for learning, a mode switching unit, a media carrier unit, a final command generating unit, a mismatch block, blocks comparing the ticket number, blocks of bitwise comparison of the answer, switching the bits of the answer, bitwise answer memory, memory of the question number and memory of the ticket number [2] ·

The main disadvantage of these devices is the necessity ¹ .most their preset ·

to form an estimate for a specific number of Errors.

The closest to the invention is a device containing a time stamp generator connected to one of the inputs of the element I, whose second input is connected to the start trigger output and the output to the error recording and time node connected to the first output of the response analysis unit, one input of which connected to the reference responses node, and the other to the response input register, and the second output of the response analysis block is connected to the correct answer counter connected to the comparison block whose output is connected to the test counter, the shift node Ablitz encoder ', display unit ^ 3], -. ..

However, this device does not allow to automate the process of selecting the grading scale and implies a large expenditure of labor and time of the teacher to calculate the grading scale before each monitoring cycle.

The purpose of the invention

is an extension of didactic

device capabilities by automating changes in the rating scale.

This goal is achieved by the fact that the device ^ containing a sequentially connected block for entering answers, a block for determining correctness. answers, a counter of correct answers, a comparison unit and a display unit, a standard input unit connected to a test counter and a response determination unit, sequentially enabled decoder, an AND element and an element or connected to a test counter outputs connected to the comparison block, entered element and is connected to the input block

The drawing shows a block diagram of the device. '".

The proposed device consists of a block of 1 input of standards, which is connected to block 2 Determining the correctness of answers and a 3-test counter, which is connected by its outputs to the OR 4 element and the decoder 5, which is connected to the input 'of the comparison unit 6 and the outputs of X 7, connected one of its input to the element OR 4. The input of block 2 is connected to block 8 for inputting answers, which is connected to the second input of element 7, and the output of block 2 is connected to counter 9 of correct answers, which is connected to block 6 6 of comparison, connected by its exits and with a display unit 10. ‘The proposed device for monitoring students' knowledge works as follows.

The transfer from the block I to the counter of 3 tests comes the number of tests in the ticket offered to the student in this control cycle. In the decoder 5, the signal from the counter 3 is deciphered, and the increments of the number of correct answers are sufficient to give the student estimates of "5", "4",

"3", "2". Depending on the number of 3 tests recorded in the counter, the increment values change proportionally. · ' _X

From the beginning of the occupation of the response input block 8, the information generated when the learner responds to the proposed tests enters in block 2, where the learner’s responses are compared with the reference responses received from block 1. By comparing the received answers of the 8th response values of the block, block 2 forms a single signal only if the compared values match. At this moment in the counter 9 correct answers, a unit is recorded.

'Eisy''Zh'yo' e-case did not happen, then the counter 9 does not change the correct answers in His own state. After entering the answers' to. All the proposed tests from the block 8, you get the "End of Answer" signal. This signal goes to the first the input of element 7, to the second input of which through the element OR 4 is connected the counter of 3 tests, which contains 5 the number of tests in the given control cycle, for which the assessment must be made.If there is a number on the counter of 3 tests, then the potential is removed from the element OR 4 on the element And 7, (θ which opens signal "End of response" from block 8 input answers received at the second input element And 7, which gives a signal to the decoder 5, "allowing the issuance of selected increments in block 6 comparison, where the comparison of increments with the number stored in the counter 9 correct answers, The number 9 of the student’s correct answers for this variant of task 20 is accumulated in counter 9. The comparison block B provides a comparison of the number of correct answers with the selected increments and the formation of the student’s assessment.

25 Depending on the result of the comparison, block 6 initiates one or four output buses' connected to block 10, in which one of the marks "5", "4" is displayed, respectively,

And 3 ΙΓ Y 2 And

The device ends the cycle of work that can be continued. the signal from block 1, which sets all the counting nodes of the device to its original state.

The proposed device for monitoring students' knowledge allows us to automate the process of choosing a rating scale, which expands the didactic capabilities of the device for controlling knowledge and saves the teacher from performing this labor-intensive operation.

Claims (1)

Claim A device for monitoring students' knowledge, containing sequentially / switched on the input unit of Answers, a unit for determining the correctness of answers, a counter for correct answers, _ a comparison unit and a display unit, a unit for inputting standards, connected to a test counter and a unit for determining the correctness of answers, tl and h This is due to the fact that, in order to expand the didactic capabilities of the device by automating changes in the rating scale, it contains consistently the included decoder, the AND element and the OR element connected to the outputs of the counter t ITS is connected to the decoder connected to the comparison unit, the AND element is connected to the response input unit. five 758230 6
