According to the results of the study, trainees prepare a report in which the processes observed by them are recorded, and pass the test to teacher C 2.

However, due to the lack of ongoing monitoring of the actions of students and their low activity, due to the nature of the well-known technology, the effectiveness of training is low. The main reason for this is the insufficient intensification of the learning process with the aid of a known device.

12 controls, first block 13 And elements, node 14 of the solution set, first block 15 of keys, second block 16 of keys, second block 17 elements And, node 18 of the solution set, switch 19 (modes of operation), node 20 of issuing tasks, error counter 21 , nodes 1, 2, 14, and 18 are combined in block 22 for entering responses of indicator 5, 8, 10, 11, and node 20 are combined in block 23 for presenting educational information.

The proposed device operates as follows.

After switching on the device, the learner uses the switch to set the repeater mode. In this mode, the node 20 issues a response of the task to be executed, in the form of a surplus message, which

the information defining the law of the operation of the encoder 4 must be transmitted. In accordance with the task, the learner types the message and the law of operation respectively on the encoder 4 and node 2. According to the signals of block 12, this information is entered into the encoder 4, which forms the correction code dp of the specified message according to a given code formation law. The generated code is issued to the transmitting register 3. The learner calculates the message to be generated by the encoder 4, and outputs it using node 14. The control register register 3 analyzes the messages generated by the encoder 4 and predicted by the learner, and also resolves by sending a signal to block 15 , indication of the message recorded in the transmitting register 3 on the indicator 5. The latter provides the possibility for the students to control the correctness of the forecast made. If both messages do not match, the control circuit of the block 13 gives errors to the switch19. This signal in the Repitor mode is sent to node 20, which gives the learner a task that offers the learner to insert a new message into the installation and a new law of the encoder 4. The delivery of similar jobs will continue until the message in the transmitting register 3 and node 14 match. . In this case, the control circuit of block 13 will generate a match signal, which, going through switch 19, will go to node 20. Upon the arrival of the match signal, node 20 will issue a task for transmitting the message and inserting it into it using a simulator. 6

According to signals from block 12, a message from transmitting register 3, through simulator b, in which errors will be entered into the transmitted message, will go to receiving register 7 and display, on indicator 8. At the node 18, the learner sets predicted detection and correction signals, which should appear in the decoding process of the message. After this message, reception register 7 is transferred to decoder 9, where it is decoded. The decoding results are displayed on the indicator 11. The control circuit of the unit 17 passes the detection and correction signals appearing during the operation of the decoder 9 for display on the indicator 10 and compares these signals with the typed learner predicted detection and correction signals at node 1B. in the event of a mismatch, the error signal is sent from

control circuit block 17 through a com, mutator 19 on node 20. This block provides the learner with a task that provides him with a repetition of previously performed operations in order to clarify to the learner the principles of decoding messages. This will continue until the control circuit of block 17 generates a match signal. This signal, arriving at node 20, will ensure that the student is given a task to switch to the Examiner mode. In this mode, the proposed device works basically the same way as it worked in the Tutor mode. However, the error and coincidence signals from the control circuits of blocks 13 and 17 to switch 19 provide, regardless of the nature of the signal, sequential issuance of tasks, and error signals go to counter 21, where their number is counted and the score that is displayed is determined by the counting results T; In the case of an unsatisfactory assessment of the signal and the mean of the error counter 21, it arrives at node 20, which issues the task for setting the repeater mode to the exchangeable one. If the student’s knowledge control is positive, the training ends.

The proposed device provides control of the truth of the knowledge of the student in accordance with the result of the control, either allows him further work, or causes the student to repeat previously performed operations until a positive outcome is obtained. A positive outcome can occur only when the student clearly imagines the principles of encoding and decoding the correction codes. The repetition of the actions of the student and the complete control of his knowledge stimulates the activity of the student and contributes to the intensification of the learning process in comparison with the known device. The known device solved only the demonstration functions and did not ensure the proper activity of the trainees.
