A device for training and monitoring the depth of knowledge of students works as follows.

The learner is provided with a series of questions, each of which has a series of incorrect answers and the correct answer entered into the device through the input unit 1

0 answers. The correct answer code is set using the coding unit 2, which generates direct and inverse signals with weights 1, 2, 4 supplied to the input of the response code generator 5. If, for example, the correct answer is the first of a number specified in the program, then the first input of the response code generator 5 is turned on, if the third answer is correct, then the first and second inputs are turned on, if the fifth, then 0 first and fourth inputs, etc. d. Using the switch 4 questions, the learner sequentially answers the questions, the correctness of the solution, which is determined by the corresponding converters 14

5 of the answer code and is indicated by the two-color light bulbs of the formers 8 of the correct and 9 of the incorrect answer, with green - the correct answer, red - the wrong one.

0 When switching to the solution of the following GB question, the results of the answer to the previous ones are saved by the memory unit 7, executed according to the scheme of the three-stable trigger on three AND-NOT elements (see, AS USSR No.

5 1072085, cl. G 09 B 7/02, 1984).

At the end of the answer to all the questions on the program, the device automatically sets a general assessment using the registration unit 10, the device operates in the training and control modes, set using the switch 11 operating modes, connected to the inputs of the generator 5 of the response code and block 6 comparison.

To increase the objectivity of assessing the knowledge of the learner, the device has a pulse generator 12 for blocking the re-entry of answers, which in the control mode eliminates the possibility of re-entering the answers in the event of a reset of the entered, for example, erroneous answers by turning off the power or in other ways. In the learning mode, the student can test their knowledge by sequentially turning on the answer input unit 1 and monitoring the formers 8 correct and 9 incorrect answers. In this case, the initial state is set using the buttons of the driver 13 of the pulse to reset the response elements. Monitoring compliance with the set time limit is carried out by block 23 of the display.

When monitoring and assessing the depth of knowledge of students in the course of their preparation for fulfilling the duties of operators of special technical systems in difficult conditions, the teacher sets a time limit for a decision to be made by setting the division ratio of a 20-pulse counter.

The clock generator 15 provides a pulse train with a repetition period that is a multiple of a multiple of time, for example, second marks.

After asking the number of the next question with a switch of 4 questions, the teacher sets the trigger 16 to the single state with the pulse from its output, opening high element from its direct output (in the presence of a high potential at the output of the element NOT 2-1) element And 17 for passing pulses from it output to the clock inputs of the pulse counters 19, 20.

When students receive a response, the pulse from the output of the switch 3 of the answer numbers resets the trigger 16 and locks the element And 17, prohibiting the passage of pulses through it to the inputs of the counters 19, 20 pulses. The leading edge of the positive potential, which is formed in this case at the inverse output of the trigger 16 when there is a high potential at the control input of the And 18 element from the output of the HE 21 element, enters through the And 18 element to the reset input of the pulse counter 20 and sets it to its initial state.

The number of pulses received at the counting inputs of the pulse counters 19, 20 is proportional to the duration of the temporary

the interval between the question and the answer. If this interval is less than the set time limit, then this number of pulses is recorded in the first and second pulse counters 19, 20. Upon receipt of the next question, the pulse counter 20 is reset, and the contents of the pulse counter 19 are stored.

If the learner exceeds the set time limit, then the potential of overflow from the output of the counter 2.0 pulses, entering the input of the element HE 21, forms a low potential at its output, blocking the elements And 17, 18. Thus

5, the supply of pulses to the clock inputs of the counters 19, 20 is stopped and the reset of the second counter 20 is prevented when the trainees respond. During the student’s answer to the question, the contents of the second counter 20 pulses are displayed on the display unit, which allows the student to independently control the current time interval and check its compliance with the set time limit.

If the student exceeds the set time limit, the overflow potential from the output of the second counter 20 pulses goes to the control input

0 switch, connecting the input of the display unit 23 to the output of the first counter 19 pulses and thereby providing an indication of the total reaction time training. All questions asked before.

5 When a group of trainees obtains equal grades, the teacher sets a high potential from all the control inputs of the switches of 22 trainees' control panels from his remote control.

0, the input of the display unit 23 is connected to the output of the first counter 19, and the total reaction time of each student is monitored for the entire set of asked questions, which allows the teacher after a series of similar tests,. to select from the group of the most trained students. Introduction of a clock generator 15, trigger 16 of the first element

0 is necessary to convert the duration of time intervals between the teacher asking questions and giving the student an answer in proportion to the number of impulses.

5 The introduction of the first counter 19 pulses is necessary to count the number of pulses proportional to the total time to make a decision on all the questions asked and to convert it into the code of the counter 19 pulses.

The introduction of a second counter 20 pulses is necessary to control the correspondence of the length of the time interval between posing the question and issuing an answer to it to the established time limit.

The introduction of the second AND element 18 and the HE element 21 is necessary to control the operation of the pulse counters 19, 20 when the student exceeds the set time limit.

The introduction of the switch 22 and the display unit 23 is necessary to control the duration of the decision interval both for each of the questions (when assessing whether its duration matches the established time limit) and for the entire set of questions asked (when the group receives equal ratings).

The clock generator 15 is made on the basis of the domestic chip 176 IE according to the well-known scheme. Elements I 17, 18 are made on the basis of the domestic microcircuit 561 LA 8, moreover, to obtain the function AND, the elements C-I-H E are connected in pairs, and the excess inputs are shorted.

The trigger 16 is made on the basis of the domestic chip 176 TM 2.

The pulse counter 19 is based on the domestic chip 176 IE 8, which is a decimal divider counter with a decoder. ;

The counter 20 is based on the chip 562 IE Kommersant.

The switch 22 is made on the basis of the domestic chip 176 LP1 according to the bi-directional key scheme.

The display unit 23 is based on typical digital indicators IN-1.

Thus, the proposed technical solution due to the introduction of a generator

clock pulses, trigger, first and second AND elements, NOT element, first and second pulse counters, switch and indicating unit makes it possible not only to control the knowledge of the trainees, but also to assess the depth of knowledge of each of the trainees in preparing them to perform duties of technical operators system in difficult conditions, even when received by a group of trainees

equal ratings.

The technical and economic effectiveness of the proposed technical solution is provided with the ability to assess the depth of knowledge of each of the trainees even

when the whole group received equal assessments, it made it possible to select the most prepared operators for performing duties, thereby reducing the probability of operator error.

The usefulness of the proposed device for training and monitoring the depth of knowledge of trainees lies in the fact that it allows you to better assess the level of training and depth of knowledge of trainees even when the group receives equal grades and select the most prepared for work as operators of special technical systems, which can be used in the training of specialist operators for a wide class of special technical systems.
