Description

The disadvantages of these devices are: limited code memory; the ability to recognize codes from neighboring students, i.e. the codes of all student consoles are set the same from the central console; there is no statistical processing and accumulation of results: ontrol of the limited output parameters recorded by the machine during knowledge control.

These drawbacks of the known devices reduce the accuracy and reliability of the control of knowledge and training, and narrow their field of application.

The closest technical solution to the invention is a device comprising a response input unit, a comparison unit, a display and recording unit, a coding unit counters 3.

However, this device has limited didactic capabilities due to the limited code memory and logging parameters, training, and also due to the lack of statistical processing of the results of input answers.

This is achieved by the fact that in a known device containing an input block of Answers connected to one display unit, a question counter AND a comparison unit connected to a coding unit connected to a question counter, one display unit and a control unit connected to the registration unit, the counter signals of the response, connected to another block of the Display, a consistently connected match block, a delay element and a shift register connected to the control block, the response input block and the second an indication unit connected to the registration unit, a coincidence unit connected to a comparison unit and a response input unit connected to the question counter, a delay element connected to the counter of correct response signals.

The drawing shows a schematic device.

It contains a remote control 1 teacher, remote control 2 students.

The teacher’s console 1 includes a control unit 3 that shifts the register 4, the counter of the correct response signals 5, the display unit 6 is the registration unit 7, the console 2 of the student enters the response input unit 8, the question counter 9, the encoding unit 10, the comparison unit 11, the 12 matches, delay element 13 and display unit 14.

A punch card is used as the code carrier. It is installed in block 10. Block 8 is designed as a typewriter keyboard with a keypad.

Names of answers with sequence numbers and response weights (numeric input).

Programs for entering answers are used external - text, book, drawing, etc. The number of correct answers to a question may vary depending on the number of keys on the remote 2 student.

The device for controlling the knowledge of students works as follows

In the control mode, having received a program with a number of questions and answers in the form of text or verbally, the student enters the answers into the device via the keyboard pools and 2 blocks 8 of the input of answers. When the keys are pressed, information characterizing the response of the student is transmitted to comparison unit 11 and to block 14, showing the correctness of the entered answers to the question.

At the second input of the comparison block 11 at this time there are potential signals of the first question codes taken from the punch card of block 10. In block 11 the signals of the codes and entered answers are converted into the resulting output signals O or and are fed to the inputs of the block 12. When a clock pulse arrives input of block 12 from block 8 of input of answers block 12 bridges the resultant signal of recording answer. to the whole question, which, after delaying element 13, enters the input of shift register 4 and into counter 5, registering the arrival of correct and and incorrect answers. The clock pulse, which was previously received from the block 8 for inputting answers to the shift register 4, prepared it for recording the next answer, and the question counter 9 switched to generating a potential signal of the next question arriving at block 10.

After the students have finished answering all the questions from the 9 questions counter, the Mortar of the 9 questions in block B of the input of answers receives a signal that prohibits further input of answers.

The teacher switches the control unit 3 to the result mode, and at the same time, the display units 6 and 14 display the results of the student’s evaluation with evaluation, coming from the output of the shifting register 4 and from the counter 5, and, if necessary (when pressing the print button in the control unit 3) , are output by block 7 for registration.

In the training mode from block 10, the signals corresponding to the correct answer codes are sent to block 14. The training device has been tested and accepted for implementation in the educational process.

This reduces the time spent on teaching

acceptance of credits is 6-10 times for one student, and for a group - more than 50 times, depending on the complexity and size of the program. Simplification of the method of management, increases the ability to control knowledge and training, as well as the likelihood reliability of the device.
