The invention relates to automation and computing and can be used for machine learning in various educational institutions.

According to the main author. St. 750543, a device for training and monitoring students' knowledge is known, comprising a response input unit, connected to an answer comparison unit and a memory unit connected to an address register, an educational information playback unit and an address comparison unit, which is connected to an adres register, an educational playback unit. information and a feature determination unit connected to the response comparison unit, the educational information reproduction unit and the control unit, which is connected to the address register, the registration unit and the comparison unit Answers, connected to the educational information playback unit, which is connected to the registration address register, connected to the teacher console, the educational process definition block, connected to the educational information playback unit outputs and. block address comparison and with the input of the remote teacher 11.

The disadvantage of this device. is that it does not allow to determine the degree of knowledge acquired by students at each stage and does not allow to analyze the quality of programs at each stage. However, the stages of the program are different in the form of the material presentation, the complexity of the rf volume of the material, and therefore the study of the time spent by students on training at each of the stages, as well as the study of the deviation of the real time of training from the specified training time within the stage may indicate the degree of learning each stage and about the quality of the training program.

The reason for this drawback is the inability to record and indicate to the teacher information about the time spent by students in mastering the material within the stage, and about the deviation of time spent by the student from the specified training time within the stage.

The purpose of the invention is to expand the di (Dactical capabilities of the device. This goal is achieved by introducing a time deviation fixation block in learning devices connected to a training information reproducing unit, a class comparison unit, a learning process definition block, and The drawing shows schematically the proposed device. The device contains a block 1 for inputting answers, associated with block 2 for comparing answers and block 3 for memory connected to one lock 4 reproducing learning information / which is connected to block 2 comparing answers, block 5 registering, block 6 determining the stages of the learning process, register 7 addresses, block 8 comparing the addresses, block 9 fixing the deviation of time to the stages of learning and block determining signs connected to the block 11 of the control, the address matching unit 8 and the response comparison block 2 connected to the control block 1 connected to the registration block 5 and the address register 7 connected to the memory block 3 and the address matching block 8 connected to the b memory 3, block 9 for fixing the time deviation by the Learning Stages and block 6 for determining the stages of the learning process, 1 stage decoder, connected to the teacher’s console 13 and time deviating block 9 for the learning stages, which is connected to the current time indicator 14 and console 1 teacher connected to the node 15 of the collection of statistical data. The memory unit 3 contains a data carrier on a film with frames and control codes applied on it and a reversible tape drive mechanism. Block 9 contains time deviation determinants, each of which corresponds to a specific stage of the training program. Block 9 is intended to determine the time spent by the Member States on. study of the stage and to determine the deviation of time spent on the study of the material of the stage from the time of study of the material of the stage in the training program. Unit 6 contains a stage driver, (not shown), connected to a decoder of 12 Pats. Block 5 contains a recorder (not shown). The proposed device works as follows. After the response is entered, the response input unit sends a trigger signal to the memory unit 3 and the response code to the response comparison unit 2, which also receives the possible response codes from the photoelectric amplifiers of the unit 4, which read the coded responses encoded on the film , Block 2 also receives signals from Block 10 about reading the codes of possible answers, which were codified on film. By bitwise comparing the response code with one of the possible response codes, unit 2 outputs a comparison signal to control unit 11. Unit 11 memorizes the Universe comparing the response code and the possible answer code and issues a short-term signal to write an error to the registration unit 5, and if an error of a certain weight is encoded in the compared code, then the error weight code from the unit 4 goes to the registration unit 5, where su (The weights of the incidental errors are.) After comparing the possible response code with the response code, the first incoming code, which is the address of the next frame, causes a signal from block 10 to block 11 to generate an enable signal to register 7 The address for recording the address of the next frame from block 4 to register 7. If the desired frame is in the direction opposite to the original direction of motion of the film, the address register 7 sends a reverse signal to memory block 3, and the direction of motion of the film is reversed. The address comparison block 8 performs a one-by-one comparison of the address of the desired frame arriving at register 7 and the code of the frame arriving from block 4 when searching for the desired frame, as well as when there is a clear signal from block 10 of determining the presence of tvii frame code. When bit-by-bit comparison by block 8, a signal is generated to stop the tape-carrying mechanism in block 3 of the memory. The stop signal is also supplied to block b, and if the code compared to the code contains a coded bit coming from block 4 to block 6, when these signals coincide, the counter of block 6 adds one to the previous state. The code of the stage being studied goes to the decoder of 12 stages, which supplies the stage code to the teacher’s console 13 to indicate the number of studied student stages, as well as the enabling signal to the input of one of the time error detectors in block 9 corresponding to this stage. Thus, at a certain stage of training, the student will connect the corresponding time determining determinant of time deviation in block 9. The input of the connected determinant of block 9 comes to allow

the stop signal from address comparison block 8, which receives the time code (it is, for example, in the code containing the frame code), which determines the time specified by the student to study the material in the step. The time code can consist of. several time codes that are summed in the determinant and determine the time intended for studying the material of several frames belonging to this stage. The ratio of the time spent by the students to study the material of this stage and the embedded input determines the deviation of the time of studying the material to the student's stage (for example, when studying the 2nd stage, the student spent 15% more time than was set).

Unit 9 to the teacher control unit 13 supplies the time code for studying the material at this stage, as well as the time deviation code for studying the material from the specified time at this stage. These codes also go to the site 15 for collecting statistical data to accumulate information about the time of study of the material and the time deviations at all stages of the training program for groups of students.

Block 9 is also connected to the current time indicator 14, which highlights the learning time remaining to think about the dose of material and the time exceeded by the student compared to the time needed to think about the dose of material (the dose of material can correspond to one frame, several frames, stage and t . P.) .

The use of the proposed device allows to determine the degree of material learning by students for each

the stage, which is determined by the material mastering time and the deviation of the material mastering time from the specified one. This allows the teacher to actively participate in the learning process of students; ss on the machines, and the indicator and registration information about the material mastery allows you to evaluate the quality of the programs in stages, which makes it possible to work out the requirements assumed by nporpattam and create programs that best implement the phased learning method.

The prior art devices do not allow detection of

the degree of material learning by students according to the time of mastering the material according to the stage and the deviation of the time of mastering the material from the time specified in stages.

When finalizing the program to the optimal option, the average level of students' knowledge will increase by approximately 0.2-0.25 b.
