The closest to the proposed

15 is a device for training and monitoring students' knowledge, 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 an address comparison unit, an address register, attribute determining unit , the response comparison unit and the error counter connected to the display unit and the address comparison unit, which is connected to the address register and the recognition block, which is connected to the control unit and the unit and responses, which is connected to the control unit 3. The disadvantage of the device can be attributed to the increased consumption of film due to the use of codes of the possible number of errors in all code combinations, even those that carry out, the transition from frame to frame regardless of the code number errors, as well as the complication of functional schemes at the expense of the control unit, the attribute detection unit and the error comparison unit. The error comparison block is not used at all transitions from frame to frame, since the selection of the training program occurs 1T very rarely compared to the choice of frame depending on the answer. The reason for these shortcomings is the absence of a block that allows the use of the comparison comparison block to compare the answers. and to compare errors. The purpose of the invention. The expansion of the functionality of the device. This goal is achieved in that the device contains a criterion task block. When evaluating and switching response codes, the first information input of which is connected to the response input block, the second information input has an error counter, the control input is connected with the educational information playback unit, and the output is with the response comparison unit. The proposed device is shown schematically in the drawing. The device for training and monitoring students' knowledge contains a response block 1, connected to memory block 2 connected to address register 3, address comparison block 4 and block 5 playout instructional information that is connected to address comparison block 4, address register 3, definition block 6 features, a response comparison block 7 and an error counter 8 connected to an identification block 9 and an address comparison block 4 that is connected to the address register 3 and an attribute definition block 6 connected to a control unit Yu and a comparison block 7 m quick advice, which is connected to the control block 1D comprises bl.ok 11 specifying criteria and estimates of switching codes from

739621, the first information input of which is connected to the response input unit 1, the second information input — with an error counter of 8, the control input — with the tutorial 5 for reproducing educational information, and with the response comparison unit 7. The response input unit 1 consists of the literal response input buttons, a decoder, a response memory trigger, and a tape drive trigger (not shown). The Blkk 2 memory contains information carrier on a film with information frames and control codes printed on it, and a reversible tape drive mechanism (not shown in the drawing). The reproduction unit 4 consists of photo-electric amplifiers of the same type converting photosignals into electric pulses and amplifying them (not shown). The display unit 9 contains a waiting multivib1) ator and an indicator lamp. Incorrectly (not shown). The device works as follows. . . After the learners have entered the response, the response input unit 1 supplies the response code to the block 11 and the tape trigger signal to the memory unit 2. During the moving film, the control codes pass by the photosensors of the playback unit 5, read, amplify, and fed to 4 devices that search for the desired frame based on the response code (or the error number code) and the codes read from the film. The codes are read sequentially while the film is moving. The response code enters the switching unit 11, which also receives the error number code from the 8 error counter. According to the signals from replay block 5, block 11 automatically connects to block 7 comparing the answers to either block 1 of entering responses or the counter 8 errors. Thus, in block 7, the comparison of answers from block 11 enters either a response code or an error number code, which depends on the encoding of the information carrier. In block 7 of the comparison of answers, this code is compared with the code received from reproduction block 5. 57 In the initial state, the device responds only to codes of possible answers or the number of errors. In block 7, when comparing the code coming from block 11 with the code coming from reproduction block 5, and if there is a resolution of this signal from the attribute determining unit 6, the response comparison block 7 will generate a comparison signal in control block 10. If none of the provided possible response codes compare with the response code (for example, the student responded in an unintended manner) or if none of the possible error number codes compare with the error number code (this feature is provided to reduce the number of possible error codes) Then a code will come in which contains a Bit Comparison and when reading such a code, block 11 will generate a comparison signal in control block 10. Signal determination unit 6 receives signals from the bits of the playback unit 5, which are occupied by distinctive features, and block 6 receives decisive signals about the presence of a code type in the response comparison unit 7, or in the control unit 10, or the address comparison unit. The control unit 10 according to the signal from block 7 memorizes the presence of a comparison of the response code and the possible response code: further, it only responds to address codes of the next frame. The first matching code of this type calls the signal from block 6 to block 10, and block 10 activates the enable signal to write the address of the next frame to register 3 of the address. The address of the next frame, received from block 5, is recorded in the address register 3. and is stored in the search for the next frame. The unit U remembers the resolution signal and does not emit repeated signals, and the device later proceeds to the next stage. The address of the next frame contains a bit of the direction of movement of the Reverse, and if the desired frame is in the direction opposite to the initial direction of motion of the film, then the address register 3 sends a signal to the reverse of memory block 2, rss to which the direction of motion of the film changes, opposite. The address comparison unit 4 produces a bitwise comparison of the address of the next frame, coming from the address register 3 and the frame code, coming from the playback unit 5, if there is a enable signal from the attribute determining unit 6. When bit-by-bit comparison, block 4 generates a signal to stop the tape-drive mechanic in block 2 of the memory. Simultaneously with the stop signal, unit 4 issues a pa; another signal to record an error, arriving at the counter 8 errors, and if an error was made during the response, then the corresponding code should be encoded with the Nohfavilno code. The signal Wrongly arrives from block 5 of reproduction after: 8 errors and if the resolving signal coincides with the signal. The counting of 8 errors is wrong, sum the error and give a signal to block 9 to indicate the error. The frame search cycle can be without comparing the response code or the code of the possible number of errors. When organizing a linear part of the program, the transition from frame to frame can be accomplished with the help of a single code in which the frame code is all zeros, as in the initial state the address register is in zero state and when reading this code with zero code the frame is compared with the zero address; block 6 issues a signal about the presence of this code in block 4, which generates a signal for stopping the tape drive mechanism, which enters memory block 3. Thus, the issuance of the next frame will depend either on the response of the events, or on the number of errors made by it. Inserting the next frame depending on errors allows you to implement branching to explain admitted shortages, and issuing the next frame, depending on the number of errors, allows you to implement adaptive tutorials in which the same material is presented several times with varying degrees of difficulty, and for a better mastery of the material, the program should be issued a program with the difficulty of presentation that will be optimal for a given student 1 In adaptive programs, initially all students are given one and
