I

The device relates to the automation of the educational process and can be used in various educational institutions.

One of the known adaptive learning devices comprises a response input unit associated with a response comparison unit and a memory unit connected to a playback unit that is connected to the response comparison unit, the error comparison unit, the error counter, the address register, the address comparison unit and the definition unit features associated with the control unit, the error comparison unit, the address comparison unit and the response comparison unit connected to the control unit associated with the error counter connected to the indicator device and comparing the error Twomey unit connected to the control unit coupled to the register address zannomu communication with the memory unit and comparison unit addresses, the output of which is connected to the memory unit 1.

This device allows the selection of the next frame, depending on the response of the student and the total number of errors made by him.

However, with the implementation of adaptive

Teachers often need to make transitions from frame to frame according to the number of errors made within each part of the program corresponding to a specific section or topic of educational material, i.e. admitted within each stage of the program. The total number of errors made by students throughout the program does not allow an objective assessment of the students' knowledge at this stage.

10 This device does not allow to determine how the errors made by the students in stages are distributed, it only determines the level of material absorption in the program. And this in turn entails an inadequate organization of the learning process: poorly learned parts of the program (steps) are re-studied along with the less well learned parts of the program, whereas greater attention should be paid to poorly learned material.

20 Thus, the device does not allow repeated branching to poorly understood steps.

The closest technical solution is a training device comprising a response input unit associated with an answer comparison unit and a memory unit connected to a playback unit that is connected to the comparison unit from, vets, registration unit, stage counter, address register, an address comparison unit and a attribute determination unit connected to the control unit, an address comparison unit and a response comparison unit associated with the control unit connected to the registration unit and the address register connected to the block memory and address comparison block associated with the memory block and the stage counter connected to the stage decoder connected to the teacher console and the error counter block of the stage connected with the teacher console, and in addition, the outputs of the registration block are connected to the teacher’s console and to the block of error counters by stages 2. This device allows the teacher to receive information on what stage of education the student is at and how many errors he made within each stage. However, this device does not allow the implementation of adaptive tutorials in which the selection of the next frame of each stage is made depending on the number of errors made by students within this stage. The reason for this drawback is the absence of a block of error comparison by stages, as well as a switch that connects an error counter by stages to a block of comparison of errors by stages during the course of this stage of the program. The purpose of the invention is to improve the accuracy of the device, as well as expand its functionality. This goal is achieved by introducing into the known device an error comparison unit for learning stages and a switch for connecting to the outputs of the learning process definition block and an error counting unit for training steps and for input of the error comparison unit for learning stages, which is connected to an educational information playback unit, an educational information feature determination unit, and a control unit. FIG. 1 shows a block diagram of the proposed device; in fig. 2 shows four types of codes with a schematic representation of a playback unit. In the training device (Fig. 1), the response input unit 1 is associated with the response comparison unit 2 and the memory unit 3 connected to the playback unit 4, which is connected to the response comparison unit 2, the registration unit 5, the 6-stage counter, the address register 7 , block 8 of address comparison, block 9 of error comparison by training stages and block 10 for determining signs connected to control block 11, block 8 for address matching, block 9 for comparison of errors by training stages, block 2 for comparison of responses associated with control block 11, connected to block 5 reg stration and register address 7; connected to memory block 3 and address comparison block 8 associated with memory block 3 and a counter of 6 steps connected to a decoder of 12 steps connected to a switch 13 and to block 14 of error counters connected to a switch 13 connected with the unit 9, the comparison of errors in the learning steps associated with the control unit 11, and in addition, the outputs of the registration unit 5 are connected to the unit 14 of the error counters in the learning steps. Counter 6 and decoder 12 are combined in block 15 for determining the stages of the educational process. The response input unit 1 consists of alphanumeric response input buttons, a descrambler, response memorization triggers, and a tape drive trigger (not shown; memory unit 3 contains a storage medium on a film with information frames and control codes and reversible codes on it. a tape mechanism (not shown in fig.). The reproduction unit 4 consists of photoelectric amplifiers of the same type that convert photosignals into electrical pulses and amplify them. The recording unit 5 includes An error calculator with a matching circuit on the counting input, a decoder and evaluation indicator lamps (not shown) Before reviewing the operation of the device, you must consider the coding of the film (Fig. 2). In the proposed device, the program has four types of codes 16, 17, 18, 19 with various functions in controlling the operation of the device. Codes 16 contain a possible answer code 29 for comparing with a response code, bit 21 "is an obligatory comparison necessary for unconditional comparison with a response code, bit 22" is incorrect, It is intended to enter a single fine score in the registration unit 5, and a distinctive feature 23, which serves to identify type 16 codes with a device. Distinguishing feature 23 contains such a combination of codes in its bits that is prohibited for other types of codes, for example, the 3rd discharge is light, and the 2nd discharge is dark. Type 17 codes contain the code of the possible number of errors in step 24, which is used for comparison with the code for the number of errors in the stage, stored in the block of error counters by training stages 14, bit 25 "is an obligatory comparison intended for unconditional comparison with the error number code stage, and a distinctive feature 26, designed to identify the type of device code (the 3rd discharge is dark, the 2nd discharge is light). Type 18 codes contain the address 27 of the next frame, by which it is necessary to “search for the next frame and distinguishing feature 28 intended for identifying the type of code by the device (the 2nd and 3rd bits are dark at the bottom). Type 19 codes contain a frame code 29, which is a binary frame number and is intended to be compared with the next frame address, bit 30 "gtap, required to enter a unit in the counter of 6 steps, and distinctive feature 31 (2nd and 3rd bit dy bottom light). In codes of all types, there is one service area 32 - a "marker" intended to form an enabling signal for reading the entire code and is necessary so that information is not read from the frames during the motion of the film. The marker must be located below (or above) the frame level, and the signal from the output of the marker photoelectric amplifier 33 is fed to the remaining photoelectric amplifiers 34-39 as a resolution. FIG. 2, a schematic representation of the playback unit 4 with photoelectric amplifiers 34-39 is also given. The proposed training device works as follows (Fig. 1). After entering the learning response, the response input unit 1 issues a response code to unit 2 and sends a tape trigger signal to the storage unit. During the motion of the film, the control codes pass by the photosensors of the reproducing unit 4, are read, amplified and fed into the blocks of the device, where, based on the response code and codes read from the film, the desired frame is searched. The codes are read sequentially while the film is moving. The response code goes to block 2, comparing the answers. This unit receives signals from the bits of the playback unit 4 from the photovoltaic amplifiers 34-36, reading the codes of possible answers and the bit, a mandatory comparison, and from the characteristic determination unit 10 signals are received about reading the codes 16. In the initial state, the device responds only codes 16. When comparing the response code with the possible response code and in the presence of a signal from block 10, block 2, a comparison signal is output from control block 11. If none of the provided codes of possible answers were compared with the response code (the student responded in an unexpected way), the type code 16 will come, which is the last among the codes 16, which contains the bit "Comparison," when reading such a code will output a comparison signal to control unit 11. Signal determination unit 10 receives signals from the bits of the playback unit 4, which are occupied by distinctive features, and from block 10, the permitting signals of the code type are received in the answer comparison unit 2, if the read code is type 16, in the error comparison unit by the learning steps 9, if the read code is a type code 17, to the control unit 11, if the code is type 18, and to the address comparison block 8, if it is a type code 19. The signal control block 11 memorizes the presence of response code and code response and generates a short-term signal to record the error in the recording unit 5, and if in the compared type 16 code the bit is coded incorrectly, which from block 4 is sent to the registration block 5, then if two signals coincide, block 5 registers and indicates an error, and also gives an error signal to the block 14 of error counters according to the stages of training. The permissive signal for recording errors from the registration unit 5 enters the block 14 of error counters by learning stages, which also receives the signal of the stage number from the decoder 12 of the stage. The decoder of 12 stages provides the enabling signal to the input of one of the counters that are in block 14 of the error counters by the stages of training and corresponding to certain stages of training. By the signal from the registration unit 5 and by the enabling signal from the decoder of 12 stages, the block 14 of error counters by stages of training summarizes the errors received by students in each of the stages. After storing the comparison signal of the possible answer code with the response code by block 11, the device then responds only to type 17. The switch 13 connects one of the counters of the decoder 12 to the error comparison block 9 through the learning steps of one of the block 14. The block 9 is connected to the counter of the block 14, which corresponds to this stage of the program. The code of the possible number of errors in the stage contained in the type 17 code and read from 34-35 bits of photo amplifiers is fed from reproducing unit 4 to the comparison unit, where it is compared with the error number code in the stage stored in one of the counters of block 14. Comparison It occurs when there is a resolution signal from the attribute detection unit 10, which is generated if the film code is a type code 17. When comparing the code of the possible number of errors in the stage with the code of the number of errors in the stage, unit 9 will generate a comparison signal in control unit 11.

If none of the incoming codes of the possible number of errors in the stage was compared with the code of the number of errors in the stage, then the type code 17 will come, which is the last among the type 17 codes, which contains the "obligatory comparison" bit when reading such a code 9 will output a comparison signal to control block 11. The device further responds only to type 18 codes.

The first incoming code of type 18 causes the occurrence of a signal from block 10 to block 11, and block 11 generates an enable signal to write the address of the next frame to the address register.

The address of the next frame, contained in type code 18 and coming from block 4 to block 5, is written to address register 7 and stored for the duration of the next frame search. The block 11 memorizes the issuance of a permitting signal and does not give repeated signals, and the device further reacts only to type 19 codes.

The address of the next frame contains the direction of movement of the reverse, and if the desired frame is in the side opposite to the initial direction of motion of the film, the address register 7 will give a signal of the reverse of the memory block 3, in which the direction of motion of the film is reversed.

The address comparison unit 8 performs a bitwise comparison of the address of the next frame, which comes from address register 7 and the frame code, incoming playback unit 4, at the resolution of the signal from the attribute detection unit 10 (about the presence of the type code 19). When bit-wise compared, block 8 issues a signal for stopping the tape-carrying mechanism in memory block 3.

At the same time, the stop signal is fed to the counter of 6 stages, but if in the compared code of type 19 the stage is coded (the signal from this stage from block 4 supplies .c. To the counter of 6 stages), then if these signals coincide, block 6 will add one to the previous state.

The use of this device allows the transition from frame to frame in each stage, depending on the number of errors made in the internal tagline.

The large number of errors made as a result of the answers of the students throughout the program does not give grounds for arguing.

that the whole program is poorly studied, since it is quite possible that most of these errors were made by students at any one stage. To learn the program, it is necessary to re-examine it.

the entire program, and a separate stage.

Thus, students will not waste time studying material already improved, but will only study material that they have not learned, which increases the accuracy and efficiency of the learning process.
