The counter 8 (FIG. 4) includes the logical element OR 21, the inputs of which are the inputs of the counter 8, and its output is connected to the input of the counter 22, the output of which is the output of the counter 8.

5 input block 18, the logical element OR 39, standing at the third input of block 18, comparator 40, standing at the output of block 18, and register 41, standing at the first input of block 18. Block 18 performs the determination of the complexity of mastering the program taking into account

0 elapsed time and mental intensity of mental work in the learning process.

The distributor 19 (Fig. 8) contains a series-connected pulse generator 42. The counter 43 and the decoder 44, whose outputs are the outputs of the distributor 19.

The device works as follows. Students receive a program, after which all units of the device are switched on from console 1. The generator 42 generates pulses that are fed to the input of the counter 43. The decoder 44 converts the binary code of the counter 43 into a positional code, ensuring the synchronous operation of the device.

A low current flows through the biosensor 14.

5 The signal from it is fed to the A / D converter 15, where it is amplified in level and converted to digital form.

Registers 23-25 operate in such a way that the first clock signal (Fig. 9, t / i) registers the state of the register 24 into the register 25, the second clock signal (Uz) - register 23 into the register 24, and the third clock signal (Us) from ADC 1.5 into register 23. Thus, the result of measuring the height of the rheoencephalogram wave at the time of recording Hi, I, + 1 and Hi + 2 is entered as follows

5 way: H, - - to register 25, D + i - to register 24, Hi + 2 - to register 23. At the output of the comparator 26, a signal with a logical level of "1 appears only in the case of Hi + //, +2, and at the output of the comparator 27, a signal with a logic level of "1 appears only at I + 1 fii-. Thus, the output voltage of the element AND-NOT 29 appears negative voltage drop, when /// I, +, that is, when finding the extremum. This voltage drop changes the state of divider 31 to the opposite. If the output element AND-NOT 29 is a logical “O (i.e., the extremum of the rheoencephalogram) and the output of the divider 31 is logical“ About, then the fifth sync pulse / y) through the OR element 30 translates the register 28 into the recording mode from the register 24 / The +, + 1 measurement value, i.e., the extremum. With the appearance of the next extreme point of the rheoencephalogram, at the output of the divider 31, the logical "1" appears, and at the output of the inverter 35 - the logical "O. At the second input of the OR element 34, the logical signal "O and the seventh clock pulse (f / y) through the OR element 34 is fed to the register 37. The comparator 32 compares the extremum stored in the register 28 with the current extremum in the register 24 and produces a control signal to the switch 33, which in turn switches the widths of the registers 24 and 28 so that in the divider 36 the lower extremum value is divided by the larger one. The result of the division, i.e., the catacrotic ratio, is recorded by the seventh clock pulse into register 37. In this case, generator 4 supplies clock pulses to the first inputs of elements And 7. If the student is actively working on the program, then his sensor 5 together with the amplitude selector 6 records the moment of depression a-rhythms of the brain and sends a signal to one input of the element And 7, to another input of which, until the correct answer is entered, the signal comes from the remote control 2. As a result, the clock pulses through the element 7 to the counter 8, on the OR 9 and the counter 38. The comparator 40 compares the states of the counter 38 and the register 41 in which the result of the catacrotic ratio is stored. If the state of the counter 38 is less than or equal to the state of register 41, then the output of the comparator 40 will be a logical "O. A signal of this level permits the passage of pulses from element AND 7 to counter 8 and node 10 through element OR 9. When the state of the counter 38 exceeds the state of the register 41, a logical "1 appears at the output of the comparator 40, which stops the counter 8 and prohibits the passage of pulses through the element OR 9. Thus, the result of the operations of block 18 means multiplying the student's active work time (/ o) by the value of the catacrotic ratio (/ CK) - When the counter 38 is filled, a signal with a logic level appears at its second output An "O" that permits the passage of the eighth clock pulse (Us) through the element OR 39 to the register 41, and a new value of the catacrotic ratio is written to it.

In order to objectively assess the workload of students, it is necessary that the filling time of the counter 38 does not exceed the period of the following rheoencephalogram impulses. The frequency of the generator 42, the size of the registers 23-25, 28, 37 and 41, the comparators P 26, 27, 32 and 40 and the divider 36 should also be chosen for reasons of the required measurement accuracy.

The value of the calculations of the average complexity of the learning program from the output of node 10

5 goes to the adder 11. From the last output, the signal goes to the inputs of the comparison unit 13 and to the indicator 12. The inputs from the block 13 also receive a signal from the counter 8, and from the output of the block 13 - to the indicator 12. However, the indicator 12 does not provide a visual indication due to the lack of a resolution signal from counter 3. If the student stops working actively on the program, i.e. is distracted, sensor 5 together with amplitude selector 6 fixes

5 the moment of the restoration of the brain's r-rhythms and signals the prohibition of the element And 7, as a result of which the clock pulses cease to pass through it. Upon the resumption of active activity, the moment of a depression of brain rhythms and

0 and 7 opens. So work goes on until the student enters the correct answer. In this case, from the remote control 2, the signal of the correct answer goes to counter 3, and the prohibition signal goes to item 7. Thus, by the time of assimilation

5 programs studying in the counter 8 recorded the time of his active work on the program, multiplied by the intensity of mental work. The adder 11 from the channel of the given student through the element OR 9 and the node 10 records the active work time of the student, multiplied by the intensity of mental work and divided by the number of students in the group. Similarly, the device operates in parallel for each student 5 s. When all the students give the correct answers, counters 8 record the time of each student's active work, multiplied by the intensity of his work on the program, and in adder 11, the total time of active work of all students on

0 program, multiplied by the intensity of work and divided by the number of students in the group, i.e., the average integral assessment of the complexity of the program.

At the same time, from the counter 3, a 5 signal is sent to the indicator 12. In this case, the indicator 12 provides a visual indication of the average integrated labor input of the program mastering. Signals from

0

the counter 8 and from the adder 11 arriving at the block 13, provide the signals at the outputs of the block 13 and the triggering of the indicator 12. Moreover, if the integral labor intensity of the student (the signal from the counter 8) is less than the average integrated labor input of mastering the program (the signal of the adder II) , then the "I level in the indicator 12; if the integral labor intensity of the student is equal to the average integral labor intensity of mastering the program, then the level II is indicated; if the integrated labor input is more than the average integrated labor input for mastering the program, then the 111 level is displayed.

The proposed device, in addition to the time spent by students on studying the program, also determines the intensity of mental work during the study of the program. Accounting for the time spent working on the program and accounting for mental intensity, allow us to find such a generalized indicator of the complexity of the program as integrated the complexity of the program. This, in turn, makes it possible to accurately and objectively assess the complexity of the program for each student, to group high-level groups of students regarding the difficulty of their learning the material, i.e. from the point of view of psychoenergy

the costs of students. All this ultimately allows to significantly increase the effectiveness of training.
