Description

The invention relates to automation and computing, and specifically to software learning and knowledge control tools designed to automate the learning process and control at various stages of work with material in educational institutions of any type.

The purpose of the invention is the expansion of the didactic capabilities of the device by providing temporary adaptation to the individual characteristics of the student and controlling the temporal parameters of his work,

The drawing shows a diagram of the proposed device.

The device contains a unit 1 for setting reference responses, a remote controller 2 for the student, a unit 3 for comparison, a unit 4 for indication and a distributor for 5 pulses. The display unit 4 contains an indicator board 6, a counter of 7 errors, the first 8 and the second 9 counters. The distributor -5 pulses contains the generator 10 single pulses, the generator 11 clock pulses, the trigger 12, the first 13, the second 14, the third 15, the fourth 16 And elements, the first 17 and the second 18 delay elements.

The device works as follows.

In the initial state, the output of the generator 11 clock pulses is closed, the error counter 7, the first and second counters 8 and 9 of the display unit 4 are reset, the trigger 12 is in the position at which the first and third elements I) 3 and 15 are opened, and second, and the fourth elements Both 14 and 16 are closed.

The learner turns on the device and proceeds to work. (The circuit for setting the device to its initial state, turning it on for operation and turning off is not shown in the drawing). When the device is turned on for operation, the generator output opens 11 clock pulses. Clock pulses from the generator output 11 clock pulses through the open first element And 13 arrive at the first counter, which begins to record the time of the student's preparation for the task.

The student presses the Start button of the generator 10 single pulses, the output of which is a single pulse, coming through the open third element And 13 to the input

information block 1 and the input of the first delay element 17, block 1 is triggered, the section of the electrical circuit of the correct answer closes in block 1, and on the screen there is a question and a number of answers to it.

A delayed single pulse from the output of the first delay element 17 arrives at the R input of the trigger and overturns it. At the first and second outputs of the trigger 12, the voltage changes, the first and third elements of AND 13 and 15 are closed, and the second and fourth elements of AND 14 and 16 are open. The clock pulses from the output of the generator I1 of clock pulses through the open second element I 4 enter the second counter 9, which begins to record the time spent by the trainees on solving the assigned task.

The learner makes a decision and again on the start button of the generator 10 pulses, a single pulse through the open fourth element AND 16 enters the control input of the comparison unit 3 and the input of the second delay element 18. The decision is made by switching the console 2 of the student to the position corresponding to the selected answer. In case of a correct answer, an electrical circuit is closed, passing through block 1 and the student’s console 2, through which the inhibitory potential is applied to the information input of the comparison block 3. The latter blocks the passage of a single pulse (an error pulse) through a block 3 of comparison from the output of the fourth element AND 16 to the input of counter 7 errors. In case of an incorrect answer, the inhibitory potential at the information input of block 3 comparison is absent. Single impulse by (.; Blunt to the input of the counter 7 errors.

A single pulse from the output of the second delay element 18 is fed to the S input of the trigger 12 and overturns it, the voltage levels at the first and second outputs of the trigger 12 return to their initial state, the second and fourth elements And 14 and 16 are closed, the pulse from the generator is blocked 11 clock pulses iia the second counter 9, as well as the passage of a single pulse through the element 16, the first and

the third elements And 13 and 15 are opened, the clock pulses through the open first element And 13 arrive at the input of the first counter 8.

Further, the flip process of the trigger 12 is repeatedly repeated. At the same time, the number of pulses recorded by the first and second counters 8 and 9 periodically increases, the indications of the task time indicator and the analysis time of the decisions made on the indicator board 6 increase.

At the end of the work, the output of the clock generator is turned off. Disconnection is carried out by the students themselves when developing a slide without a task or at the instruction of the teacher.
