The invention relates to automation and computer technology and can be used in various educational institutions in organizing an educational process. An automated class is known on the front panel of which correct response signals are placed, a student's response registration lamp, a program switch, an operation mode switch (Training, Offset), a step finder start button for changing the code, a code 1 window that is highlighted. A large number of indicator elements placed on the front panel of the console and determined by the number of workplaces in the class makes the console cumbersome and makes it difficult for the teacher to actively intervene in the learning process. To identify lagging and successful students, the teacher needs to look at all of the indicator elements, memorize them and compare them with each other, which is difficult with a large number of indicator elements. An automated class is known that contains pupils' consoles, as well as a switchboard of the consoles combined into a console, a console number indication unit, a comparison unit, a display unit for polling results, a learning stage memory block, and a matching unit 2. The disadvantage of this device lies in the fact that in the training mode the teacher is deprived of information, about the statistical distribution of places and subjects of the group. During the lesson, the teacher often has to take separate places of the new material, but in the absence of statistical information, he often does this at a wrong time, which reduces the effectiveness of training. For example, after viewing one or two workplaces, the teacher notices that students make some characteristic mistakes and begins to explain this section to the whole group, but it often happens that the overwhelming part of the group is currently studying another section and explaining they will only distract pupils, since the teacher should give an explanation at the moment when the overwhelming part of the group is studying this section. The closest to the proposed is an automated class that collects the necessary statistical data on the division of student learning sections and contains student consoles connected via a switchboard to a comparator unit, an indicating unit, a sequential stage switch; in-learning and a decoder connected to the unit comparison, student count, connected to the comparison unit, the switchboard of the consoles and the display unit 3J. However, in a known device, the teacher does not receive operational data about the stage that the greatest number of students is currently studying, because the teacher needs to review all stages, remember them and compare them with each other to work with the device, the teacher spends time and distracts from the educational process, which reduces the effectiveness of this device. In addition, the teacher’s giving out students' information in stages, which is currently studying the greatest number of students, is not justified, because these stages are purely random in nature and the teacher often has to go back to a simpler stage in explaining the more complex stage. , and vice versa. The explanations of the teacher should consistently go from simple stages to more complex ones, and these explanations should affect the interests of the largest number of students. The reference for this explanation can be the mathematical expectation of the stages being studied at the moment, as an estimate of which it is natural to offer the arithmetic average of the stages being studied at the moment.

To characterize the scattered study stages near their expectation, the standard deviation of the study stages is used. An important numerical characteristic is the skewness of the distribution curve of the studied stages in one direction or another from the center of the grouping.

Having information about the numerical characteristics of the distribution of the stages being studied, the teacher can most effectively influence the course of study. So with small standard deviations of the studied stages, the teacher can accurately explain the stage that is indicated by the mat-. Mathematical expectation. With large standard deviations and negative obliquity, it is necessary to pay particular attention to the description of the stages, the value of which is less than the value of the mathematical expectation.

The purpose of the invention is to expand the didactic capabilities of the automated class through the continuous formation of information about the course of the educational process.

FIG. 1 shows the structural scheme of the proposed class; FIG. 2blok-diagram pulse shaper.

The automated class for teaching and controlling students 'knowledge contains 1 student's consoles and 2 teachers' panel. The remote control 2 contains a switch 3, which includes time relay 4, information processing unit 5,

0 element OR 6, counter 7, block 8

indication, a group of elements And 9, shaper 10 pulses, element OR 11.

Block 5 of information processing produces a calculation of mathematical

expectations, variance and skewness - distribution of the stages being studied at the moment according to certain formulas. For this purpose, the adder 12, block 13 for dividing the codes and block 14 for memory are used in calculating the mathematical expectation.

For calculating the standard deviation, a subtraction device based on the adder 15, the exponential unit 16 (squared), the adder 17, the code dividing unit 18, the root (square) extraction unit 19, the memory unit 20 is used.

To calculate the skewness of the studied stages, block 21 was used. Power to the power (per cube), adder 22, block dividing code 23, power to block 24 (cube), block dividing block 25, memory block 26.

The sequence of operation is provided by trigger 27, element 28 and element 29 and delay elements 30-34.

The device is reset to its initial position by a time relay 4, the output of which is connected with the zeroing buses of all adders and memory blocks (not shown).

FIG. 2 discloses a functional diagram of the driver 10, made on the basis of a counter on triggers, allowing one to form the simplest sequence of pulses.

The shaper 10 contains a pulse generator 35, an AND 36 element, a count 37, HU filled with triggers 38, a decoder 39, a delay element 40, And 41 elements, an inverter 42.

Shaper 10 works as follows.

When a signal is supplied from the relay 4, the pulses from the generator 35 through the element 36 are fed to the input of the counter 37, which receives successively one of the possible states. Each of the states is converted by a decoder 39 into a signal corresponding to one at one of the outputs. After the counter overflows .37, the operation cycle repeats.

The output pulses of the decoder 39 cannot be directly used, since the transfer of the counter 37 from one state to another occurs in several stages g, which causes the appearance of spurious pulses. To eliminate the occurrence of spurious output pulses, And 41 elements are used, which are controlled by a delayed input pulse from delay element 40 and signals from decoder 39. The input signal delay. element 40 is carried out for the time it takes to set the final code combination in the counter and form the output signal

decoder 39. Inverter 42 is used to set counter 37 to the zero position after stopping the signal from relay 4 time.

5 The proposed automated class for teaching and controlling students' knowledge works as follows. .Information about the number of the stage (the number of studied sections) from the remote 1

Q arrives at the inputs of elements AND 9. At the second input of element AND 9 of the first interrogated console 1, a generator 10 intended for sequential polling of panels 1 arrives

with the enabling signal, by which the code of the stage through the elements 9 and 11 in the presence of the enabling signal from the trigger 27 (the enabling signal from the trigger 27 goes to the adder 12 if the trigger is set to

20 zero position) enters the adder 12. The shaper 10, after a polling period, provides the resolving signal to the next element 9 and the stage number will be added to the adder 12,

25 who is studying a second student. Thus, for the polling cycle, the sum of the numbers of the stages studied by each student is formed in the adder 12. Also for the poll cycle in counter 7

30 will be entered, the number of 10 units 1 polled by the shaper.

At the end of the polling cycle, the generator 10 output signal is sent to block 13, from whose output to block

5 14 memories are stored in a mathematical expectation code. Then from the output of the imaging unit 10 a signal is sent to the counting input trigger 27, it is set to one state, the same

0 signal zeroes counter 7,

After this, a repeated polling cycle begins, and due to the fact that trigger 27 is set to a single state, in the accumulator 12, no new accumulation of the results occurs, and through element 28, with a cell. OR 6 enters through element 30 the resolution signal to the adder 15, the difference of the codes from the output of which is fed to the input of block 16 to return to the square and to the input of block 21

for construction in a cube. Outputs of these

blocks are connected respectively to

adder 17 and adder 22. According

the completion of the second survey cycle in

5 adders 17 and 22 will be recorded. corresponding expressions, and from the output of the imaging unit 10, an enable signal will be fed to the blocks 18 and 23 through the And 29 element. According to the enabling 0 signal from the 32 element,

dividing the two quantities enters block 19 to extract the square root. At the output of eZlock 19, the value of the standard deviation is obtained,

5, which is recorded in memory block 20.

According to the signal from element 33, unit 24 cubes this value. The signal from the element 34, the block 25 performs on the basis of data from blocks 23 and 24, the computation of skewness. Its value will be entered into block 26. Since i-KaK blocks 14, 20 and 26 are connected to block 8, the values of the expectation, the mean square deviation and skewness will be displayed on the teacher's information board.

Since the output of the AND element 29 is connected to the input of the relay 4, the signal of the And element 29 is triggered. At the same time, the driver 10 stops its operation at the time determined by

relay 4. This time is chosen sufficient for reading information from block 8.

After some time has elapsed from the output of the relay 4, a pulse is applied to all adders and memory blocks, by means of which they zero, the driver 10 is started and a new control cycle begins.

In the proposed automated classroom, for the training and control of students' knowledge, comprehensive information is provided on the distribution of the stages being studied, on the basis of which the learning process can be conducted most effectively.
