Description

The invention relates to technical means of training and can be used to control knowledge in various forms of employment. According to the main autorum, reference number 830502, there is a device containing the first and second registers; the first outputs of which are connected to the inputs of the respective display units, the first and second switches, the outputs of which are connected to the corresponding inputs of the summation node and. analysis of responses, the control output of which is connected to the control input of the second register, the other inputs of which are connected to the corresponding outputs of the first register, connected, through a coding unit, to the inputs of the first switch, the control input of which is connected to the first output of the teacher console, the second output which is connected to the control input of the second commutator, the other inputs of which are connected to the outputs of the input input box ij. However, this device can work only in one mode of knowledge control, and cannot be applied in those modes, where the student must control the poorly absorbable material with the device and re-answer questions. In this case, the learner answers all questions until the end and only after that the result of the answers is analyzed, the attention of the student does not focus on incorrect answers, and he is allowed to reject the next question without giving a correct answer to the next question. In addition, the trainee must necessarily answer this question in order to proceed to the next one. If he does not know the correct answer, he must enter any answer in order to proceed to the next question, which is not correct from the point of view of pedagogy. The goal is achieved by the fact that the operation mode switch, the signal response driver, the trigger, the AND element and the NAND element, the output of which is connected to the first IN input of the AND element, the first input with the trigger output, the second input is connected to the mode switch and the third input is connected to the output of the summation and response analysis node, the input of which is connected to the first1 1 output of the shaper1 signaling the end of the answer, the second output of which is connected to the second input of the element AND the first input the trigger, the second input of which is connected to the output of the response input block, the output of the AND element is connected to the first register. The drawing shows a block diagram of the device, which works in Regime Control and Training. The device contains a register; 1 with indication of the number of the question being answered, coding unit 2, with which the reference answer is dialed, additional coding switch 3 from the control panel, answer comparing unit 4, in which the reference answer is compared with the answer entered by the students, summation and analysis of the answers adder ..6 numerical answers to the question ,, block 7 input answers, the second switch 8, increasing the number of encoding options, register 9 numbers of incorrectly answered questions, .blocks 10 indications, console 11 teachers, block 12 control, indicator 13 of the number of errors, switch 14 modes of operation, shaper 15 signals of the end of the answer to a question (button with the formation of two single signals, one - when the button is pressed, the other - when released) for two modes of Monitoring and Training, trigger 16, element AND 17, element IS-NOT 18. Register 1 with indication of the number of the question being answered performs a change of the response code when switching from one question to another through mechanical coding unit 2 and switch 3 of additional coding from the control panel. Block 4 comparing the answers when the reference response, specified by blocks 2 and 3 and register 1, does not coincide with the sum received in adder b when typing the answer in block 7, generates an invalid response signal. Through the second switch 8, which increases the number of encoding options, the numeric responses from block 7 are entered into the adder b. The first signal from the output of the imaging unit 15 turns on the block 4, the second through the open element And 17 switches the register 1 to the next question in the Control mode, in the Learning mode, the switch only takes place when the answer is correct. The numbers of questions that were answered incorrectly are stored in register 9. B. Depending on the mode of operation set by switch 14 of modes of operation and the result of the answer received from block 4, is permitted or prohibited by element AND-HE 18 through element. AND 17 switch register 1 to the next question. The trigger 16 serves to generate a signal. I don’t know, i.e. if the student does not know the answer, he presses the button on the driver 15 without typing the answer in block 7.

When the device operates in the .Control mode, the output of the switch 14 of the signal operation modes is not present, as a result of which the output of the AND-NOT 18 element will be a signal and therefore the AND 17 circuit is constantly open in this mode. At that, the number of the first question is indicated on 1, from its first output through blocks 2 and 3 to block 4 a reference response signal is given. The trainer dials in block 7 the answer to the first question, which through the switch 8 is entered into switch 6. Then the learner presses and releases the driver button 15. When pressed, the signal goes to block 4. If the answer is correct, the signal does not go through block 4

When releasing this button, the second signal through the element And 17 switches the register 1 to the second question and sets the adder b to the initial position. If the answer is incorrect, the error signal from the output of block 4 compares the responses is sent to register 9, in which the number of the incorrect answer is stored. If the student does not know the answer to the question asked, he will press and release the driver 15 button without dialing the answer in block 7, and the signal from element 15 will switch to the next question through element 17 and the error will be entered into register 9. After all the answers to all the questions have been completed, the 10 terminators and the number 13 error indicator are included.

In the Training mode, the device operates as follows.

From the switch of 14 modes of operation, the signal is fed to the input of the element 18. When dialing a response in block 7, the signal from its control output sets the trigger 16 to

and logical circuit

That And 17 opens. If the answer is correct, the scheme works as in the Control mode, if it is wrong, while pressing the imager button

15-signal Error of block 4 enters input of element 18, locking element AND 17. Therefore, when the button is released, the signal from the second output of the driver through the closed element jH 17 to the input of register 1 does not pass, but only sets a trigger

16in poloashenie Oh. The student replies to the same question

trigger 16 from block 7 is set to position. If the answer is again wrong, the Error signal again locks element 17 until the learner of the answer set in block 7 presses and releases the shaper 15. When the button is released, the signal switches the element 17 through openings {because trigger 17 is in position O) register 1 from one question to another.

Just like in the Control mode, the incorrectly answered question numbers are spelled by the register 9. After answering the last question, the indicators 10 are turned on.
