The invention relates to automation and computing and can be used to teach various educational institutions.

An adaptive training device is known that contains a communication unit with a computer, a decoder, an input unit, a controlled overhead projector, a screen, a photosensor unit, a logic unit, a Q evaluation unit, a display unit 1.

A disadvantage of this device is its complexity.

An adaptive learning device is also known to contain a response input unit associated with a response comparison unit and a memory unit connected to a playback unit that is connected to the registration unit, the address comparison unit 20, the address register, the response comparison unit and the definition unit signs connected to the address comparison unit, the control unit and the response comparison unit connected to the control unit that is connected to the registration unit and the address register connected to the memory unit and the comparison unit ENA output. which is connected to the memory block 2} 30

This word allows you to select the next frame, depending on the response of the student, and thus implement extensive programs. However, in this device, in order to go to the necessary program frames on a film, it is necessary to encode variants (standards) of the answers of the student, which leads to a complication of the programs.

Closest to the invention is a device, comprising a response input unit connected to a memory unit connected to an address register, an address comparison unit and an educational information reproducing unit that is connected to a base comparison block, an address register, an attribute definition unit, an answer comparison unit and an error counter connected to the display unit and to the sparse block, which is connected to the address register and the attribute definition block, which is connected to the control block and the response comparison block which is connected to the control unit connected by the address register, and also contains the unit for setting the evaluation criteria and switching response codes, the first information input of which is connected to the response input unit, the second information input with an error counter, the control input information, and the output is with the block comparing answers Z. The disadvantage of this device is the need to encode on the film the answers of the student or the number of errors made by the student. A large number of response standards or the number of errors leads to an increase in the consumption of program carrier, an increase in the laboriousness of designing and producing programs, and an increase in the search time for the desired frame. The purpose of the invention is to simplify the device. This goal is achieved by the fact that in a known device containing a response input block, connected to the evaluation criteria block and the memory block connected to the register, the address rum is connected to one of the comparison blocks and the educational information reproduction block that is connected to the first the comparison unit, the address register, the educational information feature detection unit, the counter, the evaluation criteria setting unit and the registration unit connected to the first comparison unit and the evaluation criteria task unit connected to the second second unit alignment, the first comparing unit is coupled to the address register and the block determining characteristics of educational information, the second comparing unit is connected with ret giste address counter and connected to block certain features of the training information. The drawing shows the block diagram of the proposed device. The device contains a response input block 1 connected to the block 2 of the evaluation criteria and the memory block 3 connected to the educational information playback unit 4 connected to the block 2, the registration block 5, the address comparison block b, the address register 7, the counter 8 and block 9 for determining the characteristics of the account information connected to the address comparison block b and with the counter connected to the comparison block 10 connected to the address register 7 connected to memory block 3 and address comparison block 3 connected to memory block 3 and block 5 reg tration connected to block 2, a communication unit 10 zannomu comparison. The device memory 3 contains a reversible tape drive mechanism and a storage medium on a film with information frames and control codes printed on it. A film program contains two such codes with different functions in the operation of the device. The code of the first type contains the address of the next frame by which the next frame should be searched, the bit of the code of the number of errors or the code of the answers of the student to organize transitions in the training program is either about the number of student errors or answers, and also contains one a dark, under distinctive sign, intended for the cognition of the code of the first type by block 9. The codes of the second type contain the frame code, which is the binary frame number and is intended to be compared with the address of the next frame, bit Incorrect and one bit d, e.g. light, a feature code of the second type. The proposed adaptive training device works as follows. After the answer response has been entered, the response input unit 1 supplies the response number code to unit 2 and a tape trigger signal to memory unit 3. During the motion of the film, the control codes sequentially pass by the photosensors of the block 4, are read, amplified, and fed to the blocks of the device. According to the signals from block 4, block 2 automatically connects to block 10 of the comparison from either block 1 of entering responses or block 5 of registration. Each possible variant (number) of the response of the student or his number of errors on the film is encoded with a code of the first type, which is in a certain order among other codes of the first type. The first order code of the first type corresponds to the first answer option or the first option for the number of errors, the second order code of the first type corresponds to the second answer option or the second option for the number of errors, etc. Counter 8 determines the number of codes of the first type in the presence of an enable signal from block 9 and delivers the code to comparison block 10. Block 10 performs a one-by-one comparison of the counter code 8 with the number code of the student’s response number or with the variant code of the number of student’s errors (for example, the third variant of the student’s answer is compared with the third one of the first type). If the counter code 8 matches the number of the response number or the error number option code, comparison block 10 outputs a comparison signal to address register 7, in which block 4 records the address of the next frame of the first type read code. The address register 7 is written once. In order to reduce the number of codes of the first type in case several response options or the number of errors determine

one transition in the program, the code of the first type can contain a code that can be used to make a sequential or one-time increase in the contents of counter 8 by several units at once, or to write a bit into the register 7 of the address of the next frame. This additional code and the signal for recording are received from block 4 to counter 8. Thus, each transition from this frame corresponds to a specific code of the first type.

The address of the next frame may contain an encoded bit of change in the initial direction of motion of the film, fed to the memory unit 3. Block 6 performs bitwise comparison of the address of the next frame, coming from register 7 and the frame code, coming from block 4, when the permitting signal from block 9 is about missing the second type code. When a bit comparison is performed, block 6 generates a signal to stop the tape mechanism in memory block 3 and an enable signal to record errors in registration block 5 if the error signal is coded in the corresponding bit of the second type code (Incorrect).

The proposed device allows to significantly simplify the program by eliminating the response standards of the increasing or the number of errors made by it, therefore reducing the consumption of program carrier, reducing the search time for the desired frame, increasing the programming convenience and reducing the laboriousness of program design and production.

When using this device, the consumption of film occupied by the control codes (excluding the frame address codes) is almost halved.
