Description

 The invention relates to technical training tools and can be used in organizing the educational process with elements of programmed training, in particular in adaptive training systems built on the basis of a computer. Automated classes are known that contain logic, control, and signaling. The training program is represented by overhead projectors and projectors from a loop of film. These classes have a sufficiently high level of automation and provide the opportunity to select and present the next dose of educational information as the learning is mastered. programs1mmy 1; |. The disadvantages of the well-known classes are: the high cost of the system. group training. due to the fact that each workplace of the trainee is equipped with individual complex in manufacturing, expensive and low in reliability specialized cinema-projection blocks of considerable size and high noise level during operation of these blocks; short service life of the carrier of educational information (photo-film); the inability to promptly correct information. Automated classes are also known that contain a modification of a tape recorder (drums with a ferromagnetic layer} with programmed control, on the tape (drum) of which training programs (training information) are recorded, control tips and controls 2. However, known (and automated classes have a high cost of trainees (each console, except for a tape recorder, must contain a specialized control unit); small didactic possibilities due to the limited amount of educational information placed on new information, which significantly reduces the quality of these training and control systems, the considerable size of the students' remotes} the complexity of operational service due to the large number of tape recorders. The closest in technical essence to the proposed is an automated class. students and consisting of

an electronic digital computer connected to a console co-switch, connected to the teacher's input and to the outputs of the students' remotes, a memory unit whose output is connected to the switchboard of the consoles through the switching unit of the memory zones and the information output unit connected to the informational outputs of the consoles the trainees and the teacher’s console, the computer access unit, connected to the signal outputs of the trainees and the computer, the memory zone distribution unit, the input Whose are connected to the information receiving unit and to the computer access unit, and the input is to the memory unit, the priority access unit is to the selected console connected to the signal output of the teacher’s console, the computer and the memory switch unit, the signal processing unit alarms, connected to the control panel and the information output unit,

The block of memory stores arrays of possible options with training, explanatory and other information for presenting the students in the process of learning or knowledge control. The automatic analysis of students' mistakes and the issuance of material are also carried out here. the explanation of these errors, which is also stored in the respective arrays of the memory block, in addition, ensures that the student works at a convenient pace and needs a degree of adaptation to his individual characteristics.

The disadvantages of this class are the large cost of 1 s; PCs because of the need to have a large amount of memory and high speed in it, since all the training and control information is stored in the PC; limited number of student consoles, caused by the technical capabilities of existing digital computers, limited educational opportunities due to the fact that the presented educational information is given to the student consoles only in alphanumeric form,

As practice shows, only one control program consisting of 30 questions, according to one of the options, by df-selective input of an answer (four alternatives to a question) occupies only 4,000 bytes of machine memory, and in the control program - on average about 1000 teams. The implementation of the adaptive learning process is possible only if there are several such programs,

 The purpose of the invention is the expansion of didactic opportunities, a class in the forms of the presented video information.

(alphanumeric, graphic, illustrative, etc.), as well as the ability to serve an unlimited number of student consoles, by using to store all the educational information of long-term storage device made in the form of a storage device and the presentation of frame-by-frame magnetic video recordings.

At the same time, the cost of a class is reduced due to the use of a computer with a smaller amount of RAM and lower speed.

This goal is achieved by the fact that in a well-known automated class for teaching and controlling students' knowledge, there are series-connected student consoles, a driver for controlling pulses, a program control unit, a switch panel, a teacher console, two code distributors, and a memory block connected to the second output. the input of the program control unit, the priority unit connected by the input to the second output of the teacher’s console, and the output to the third input of the program control unit, the inputs of the consoles The secondary inputs are connected to the second outputs of the console switch, and the second inputs are connected to the second inputs of the first code distributor, the second output of the control pulse driver is connected to the second input of the second code distributor. the input with the second output of the first distribution code, the third input with the second output of the program control unit, the first output with the second input of the console switch, the second output - with the third input of the second code distributor, the fourth input of which is connected to the second output of the visual information input unit connected by the third output with the third input of the switchboard of the consoles,

The drawing shows schematically the proposed automated class for teaching and controlling students' knowledge.

the class contains the teacher 1 console 1, the switch 2 console, the priority block 3, the first valve 4 codes, the console 5 trainees, the program control block B, the control pulse generator 7, the memory block 8, the second code distributor 9 block 10 match blocks and the input block 11 visual information.

Claims (3)

Unit 11 provides storage and presentation of teaching and methodological information, as well as issuing personnel number codes, training course numbers, correct answers, and question weighting factors, and can be made on the basis of the L1-08 serial household tape recorder which, thanks to the use of well-known special cassettes Ensuring the infinite movement of the magnetic tape ensures the reproduction (from a tape glued into a ring) of video frames of the oblique-line magnetic video where each line is sponds to one frame information teaching methods. The Electronika V1-08 serial video recorder produces a recording density of 25 frames per 7.9 cm of the length of a magnetic tape at a reading speed of 7, 9 cm / s and, for example, when control programs are monitored on a tape glued into a ring 30 control frames in each program, and training information frames - 50, according to the principle, where any frame of any list is separated from the previous or next frame of the same list by the same number of frames, we get the total number of frames on the tape 1500/750 cont. rolling frames and 750 training information frames resulting from 15 one-time duplication of a 50-personnel array of training information frames), and the length of the magnetic tape ring is 4 m 74 cm, the maximum time between randomly presented control frames of the same however, the control program is 2 s, the maximum time between the presentation of any information frame is 4 s. Moreover, when unit 1 operates in continuous playback mode of a tape glued into a ring from its outputs, video signals of reproduced frames are sent to one of the inputs of switch 2, personnel numbers and training course numbers -., To one of the inputs of block 10, and the correct answer codes and the coefficients of the weights of the questions — to one of the inputs of the distributor 9. Block 10 provides detection of the moment of presentation of the necessary frames of educational information, the codes of which come from the output of block 11, to the corresponding consoles 5, and also carries out A blocking process that prevents re-presentation of control frames to this student. At the time of presentation, the current frame of educational information is transmitted to a video viewing device (TLU) of the corresponding console 5 with memory. For example, a storage electron beam can be used as a storage element of the TLV: Signal signal type LN18, and as a display of the screen - television. CRT. This ensures that any form of video information is displayed as reproduced by block 11, the code of the number required to show a frame of this or another course comes from the output of the distributor 4, or from the output of block 6, based on the training program embedded in it. Block 10 consists of N (n + 1) memory registers known in digital computing, (where N is the number of consoles 5, n is the maximum number of presented frames), the outputs of which are appropriately connected to + 1) inputs known in digital computing, coincidence codes, and the corresponding NXn memory registers memorize the codes of the numbers of already presented frames, and the N (n-f 1) memory register - the code of the number of the course being monitored, specified either by the teacher, or by the trainees, or training program. The signal at the output of the Nth coincidence circuit appears only when the course number codes (current and specified) match and the current value of the frame number code does not match the number codes of the presented frames, and this signal goes to switch 2 and to distributor 9 and, in addition, with the help of it eTQH recorded the current code of the frame number to the corresponding Nxn memory register. An automated class for teaching and controlling students' knowledge works as follows. Before starting work, a training program is entered into block 6 and the memory registers of block 15 are reset to zero. At the start of the class, block 11 is turned on, and the students choose a controlled or radiated course from the block 11 on the magnetic tape, the code of which is 5 enters the distributor 4, from the output of which goes to the corresponding memory register of the block 10. If the work of the students in the system is carried out manually by the teacher, the teacher himself sequentially enters (using the corresponding remote control keys 1) codes of numbers of information frames and courses being monitored or studied, which arrive at the input of the distributor 4, and then similarly described. If the trainees work in the system is carried out in accordance with the training program laid out in block 6, then the code numbers of the training information frames are successively (in accordance with the training program) are transferred to the corresponding memory register of the block 10. At the moment of coincidence of the current value of the course number code ( the output from block 11) with a code that has on the corresponding memory switches of block 10, and the discrepancy between the current value of the code of the frame number and the codes of the frame number already presented to this student, the output corresponds to A block-10 matching circuit appears where a current frame of training information is output to the corresponding cathode tubes of the consoles 5, and using the distributor 9, block 8 records the correct answer codes and the weight coefficient of this frame (this is for the controlling frame) . Answering the questions posed, the learners press the corresponding keys on the remote control 5 to enter the answer in block b. Next, when you press any of the keys on the information output of the console 5, the code of this key appears, and on the signal output a signal of readiness of the response appears. The readiness signal of response from each console 5 enters the driver 7, which transfers block 6 to a subroutine to check the actions of this trained and, moreover, controls the distributor 9, provides connection to block 6 of the memory allocated for this training zone in block 8. Simultaneously with the information output of the console 5, the code for the key pressed by the student enters the distributor 4 and from there through the distributor 9 is entered into the corresponding memory zone of the block 8. The block b, having received the readiness signal from the corresponding console 5, the student’s answer with the correct answer arrives at block 8, resulting in block 6 using switch 2 informs the student of the correctness of the entered answer, or the further presentation of training information frames continues, or by a signal from block b-using block 10 logical disconnection of the given control unit 5 is carried out, for this purpose, the zero code of the course number is entered to the corresponding memory register of the unit 10, and the block b forms the final estimate of the given student and using the switch 2 issues it to the control unit 1, The teacher can control the work, from the trainees behind the console 5. For this, on the remote, 1 key with the number of the controlled remote 5, it generates a signal to access the selected remote, This signal is disbanded in block 3, and the block b with the help of switch 2 emits .the remote 1 information about the results of the student’s work, which is stored in block 8. The use of the computer-aided learning system of students ’knowledge and knowledge control greatly expands the didactic capabilities of the class due to the possibility of presentation; students not only alphanumeric information, but also graphic, half-tone, illustrative, while reducing the cost of a computer at the same time by using a computing machine with lower speed and RAM size. Thus, we obtain the following positive effect: a) the possibility of presenting various video information; b) the ability to simultaneously service an unlimited number of learning consoles; c) lack of computer loading when presenting educational information; d) ease of incorporation of the proposed system into closed loop television systems available in many educational institutions in the country; e) reducing the cost of the system.
