Description

The invention relates to technical means used to train and control the knowledge of students in any branch of knowledge.

Devices for knowledge control and training are known, containing blocks for entering tickets, entering answers, changing operating modes, memory and comparing answers, changing the structure and highlighting questions, information boards.

However, such devices have relatively small didactic possibilities, for example, a ticket contains one question that can be answered only with one correct answer, chosen from several suggested ones (i.e., there are only a few questions around). The drawbacks of the devices are the difficulty of making tickets with the appropriate jumpers applied to them, the presence of a block for reading codes from tags, the complexity of the block for entering tickets, the difficulty of entering answers using a dialer, etc.

The purpose of the invention is to expand the didactic capabilities of the device, increase the objectivity of the assessment of knowledge and ease of handling.

This is achieved by introducing a decoder into the device, the first input of which is connected to the second output of the ticket entry unit, the second input to the output of the mode changing unit, and the third input to the third

output block input answers. The first output of the decoder is connected to the second input of the comparison unit, the second output to the input of the second information board, and the third output to the third input of the block for changing the structure of questions.

The structural scheme of the proposed device is shown in the drawing.

The device consists of a ticket entry unit 1, a decoder 2, a response input block 3, a comparison block 4, an answer memory block 5, a question highlighting block 6, a question structure changing block 7, a mode changing block 8 and two information boards 9.

The ticket is made of dense material, such as cardboard, with the text of a full examination ticket printed on it, consisting of questions and suggested answers (correct and incorrect).

The device has introduced the possibility of introducing into the program such questions that must be answered with several correct answers.

At the bottom edge of the ticket there are small cutouts for coding tickets.

The ticket entered into the device by the examinee himself, encodes the ticket number and thereby collects one of the decoder circuits along which the voltage falls on the second

information board 9. The numbers shown on the indicators repeat the ticket number. The number of tickets different from each other by the code is determined by the number of combinations of the number of bits applied in block 1 of the ticket entry.

After entering the ticket, the device is ready for operation. The examiner or student presses the button "The answer is ready, and in block 6, the first question and suggested answers to it are highlighted.

Simultaneously with the transition from the previous question to the next one, which occurs when you press the corresponding answer key, the ticket entry unit 1 changes the circuit in the decoder circuit 2 depending on the ticket number.

In the case of asking questions that need to be answered with several answers, each correct answer triggers the blocking circuit of block 7 of changing the structure of questions and turns off the circuit along which the signal has just passed. The correct answers are memorized by memory block 5.

Comparison unit 4 summarizes the scores for answering questions; moreover, depending on the complexity of the question, a different number of points corresponds to the correct answer. For example, if the answer to a question consists of sand components, then one point is given for each of them, if the question requires a monosyllabic answer, then depending on the complexity of the question two or three points are given.

With the correct answer to all questions of the ticket, the total score is 13 points, which corresponds to an "excellent" mark given to the examinee with the highest required level of knowledge. With a score of 12-II points, the score is "good, 10-9-" is satisfactory, if the number of points is less than 9, then - "not satisfactory.

If the level of requirements for an examiner is lowered, for example, when passing exams for a lower qualification rank, the grade “excellent gets an examiner for 12 points,“ good - for 10, etc.

Simultaneously with the evaluation, block B highlights questions that were answered incorrectly or incompletely.

The device’s circuit returns to its original position automatically after the ticket is withdrawn from block 1.

By the unit 8 for changing modes of operation, the device can be transferred from the control mode to the training mode. In this case, it is not the tickets that are entered into the device, but the training cards compiled similarly to the tickets. On the digital indicators of the information board, the card number lights up. The correct answer to any of the questions the student can find out when requesting the "Number of the correct answer, after which this number lights up on the scoreboard.

Subject invention

A device for knowledge control and training, containing a ticket entry unit, the first output of which is connected to the first input of the block of changing the structure of questions, to the second input. which is connected to the first output of the response input unit, connected by the second output to the first input of the questions highlighting unit, to the second input of which is connected the output of the response memory block, connected by the input to the first output of the comparison unit, the second output of which is connected to the input of the first information board, and the first input to the output of the block of change of the structure of questions, as well as the block of modes of operation, characterized in that, in order to expand the didactic capabilities of the device, a descrambler connected by the first input to the the second output of the ticket entry unit, the second input to the output of the mode changing unit, the third input to the third output of the response input unit, the first output to the second input of the comparison unit, the second output to the input of the second information board, the third output to the third block input structure changes questions.
