The teacher 1 console includes: a block 3 of the display board 4 of the display, a block 5 of response analysis, a block of 6 memory, a switch 7, an executive printing mechanism 8, and a block 9 of entering reference responses. Each console 2 contains a shift register 10, a coding unit 11, a response input unit 12, a display unit 13, a time counter 14, an AND 15 logic unit, an evaluation signal generator 16, a time stamp generator 17, a correct response counter 18, a control block 19, a logical AND element 20 delay element 21, comparison unit 22, including shift register 23, symbol number register 24, AND 25 logic elements, OR 26 gate. In each console 2 of the student, the control output of control block 19 is connected to the first input of the logic element and, 20, sec second input of which is connected to the generator 17 ngyhodu timestamps logic element output. And 20 is connected to the first input of the time counter 14, the second input of which is additionally connected to the corresponding output of the switch 1 and the first input of the shift register 10, and its third input is connected in addition to the second input of the shift register 10, the input of the correct answer counter 18, information output the control unit 19 and the input, the comparison unit 22, the output of the time counter 14 is connected to the input of the display unit 13 and the corresponding information input of the memory unit 6, the information output of the response analysis unit 5 / connected to the input m Pec melting actuator mechanism 8 uchaschihs learning apparatus operates as follows. - Before the start of classes, the teacher prepares in advance a list of test questions and an answer code: to them, including the codes of the amount of time allotted to think about each answer, on the basis of average statistical data. Then, using the keyboard of the 9th input of reference responses, it enters the response codes in memory block 3 in accordance with the address code (question number). However, the teacher does not provide any information about the answer. At the beginning of the lesson, the teacher reports the list of test questions. The operation starts: from the moment the Start button (not shown) of the control unit ME is pressed, the shift registers 10 and 23, the correct answer counter 18, the character number register 24 and the time counter 14 are reset. The signal code of the address of block 3 memory, delayed in the element 21 of the delay, through the switch 7 enters the block 3 memory and transfers the information typed by the teacher on the keyboard, in the register 10 shift, counter 14 vrekyuni, register 24 symbol numbers and block 6 memory ti. In register 23, the sequence numbers of characters are fixed, not subject to the conditions of commutativity (characters, the order of which input must be taken into account), and in block 3 of memory 3. the next receipt from the control panel of the answer with the data code is recorded. The time counter 14 records the number corresponding to the time interval that is allotted for the response to the question. The signal Start of operation is fed to the input element And 20 and gives permission for the passage of the clock frequency of the generator 17 to the input of the subtracting time counter 14. From this moment, the countdown of the time remaining for the student to ponder the answer begins, the second is indicated in a convenient form for the learner at block 13. In addition, at block 13 the time for pondering the response is indicated with a plus sign and the penalty time is minus. Next, the students, using the keyboard (not shown) of the input unit 12, answers, input the received response into the register 10 through the coding unit 11. In this case, the code of each key, Tve. the number that she puts in register 10 is subtracted from the number previously recorded there from the teacher’s workplace. When entering characters, the order of input of which must be taken into account, the OR element 26 generates a signal to shift the information in register 10 by one bit. If the answer is correct, all bits of the register are in the zero position. At the same time, AND gate 15 receives an enabling signal, preparing it for the signal from the Result button (not shown) of the control unit 13. After dialing the answer, the student presses this button. The signal from it is fed to the second input of the element 15 and, in the presence of an enabling signal from register 10, is fed to the input of the counter 18 of correct answers, which feeds the signal to the display 4 and to the memory block 6. The signals from counters 14 and 18 arrive at shaper 16, which generates an assessment of students, depending on the accuracy and time to consider the answer. Requests for servicing remote controls 2 students arrive at the switch

7, which sequentially polls all of the consoles 2 and in turn connects them to memory block 3. The request contains an address code for the main memory, where the answer code for the given question is stored. In accordance with the address code, the response code is read into the register 10 and into the counter 14 of the time of the working console 2, from where 6iaLn is made salnpoc.

After the answers of the participants to all the posted questions, the teacher of the Hc1 presses the Request button (not shown) of the block 9 of entering the standard answers. The signal from the button enters the block, 5 analysis of responses, which analyzes the accumulated data block of the response code and the correct answers to them. Unit 5 selects the answer code corresponding to the question on which the most errors were made (the most difficult question), and highlights the answer code on the 4 display board. In addition, the teacher can press the Request button again, and the block for analyzing answers 5 highlights the following response code on the display 4, corresponding to the second, for difficulty, etc.

In order to establish the initial analysis of the response analysis unit 5, the teacher presses the Reset button of the reference answers input unit 9.

DP documenting the results of the students' answers, the teacher presses the Print button of the block 9 of entering this eleven answers. In this case, block 5 displays the Hai executive printing mechanism 8 and the results of the students' answers with indication of the time they spend thinking about each question, as well as the arithmetic average time spent by the students thinking of each individual question.

Thus, the proposed facility automates the process of collecting the results of students' responses, and also evaluates knowledge by two parameters — by the correctness of the answer and by the time it takes to study.

answer, i.e. increases the number of controlled parameters. This improves the accuracy of knowledge control, as well as increases the effectiveness of training.
