Description

one

The invention relates to the field of automation and computer technology, in particular to the technical means of training, and can be used in the organization of programmed training in various educational institutions.

A device for training and monitoring is known, which comprises input, comparison, and memory of answers, reproduction of educational information, management and registration 1.

A disadvantage of this device in the Q "control" mode is the possibility of issuing all control frames from one topic or program section and the impossibility of issuing control frames randomly on different and strictly fixed topics of the control program. five

The closest technical solution to this invention is a device for training and monitoring students' knowledge, containing 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 that is connected to a register the address, the unit for reproducing the educational information and the unit for determining the signs, connected to the unit for comparing the answers, the unit for reproducing the educational information and the control unit, which is connected It is assigned to the address register, the registration block and the response comparison block, which is connected to the educational information reproduction block, which is connected to the address register and the registration block 2.

This training device works according to an extensive program and it can be used as a control device, but the control is not carried out qualitatively, since there is no random selection of training information in the device.

Blocks of random sampling of known devices have the disadvantage that they stop the tape mechanism at a random point in time and cannot issue questions strictly on fixed topics, which reduces the accuracy of training.

The reason for this drawback is the execution of a random sampling unit in the form of a generator and its connection to a tape drive mechanism.

The aim of the invention is to improve the accuracy of training.

The goal is achieved by the fact that the proposed device contains an address switch, a counter and a random signal generator connected to the counter, which is connected to the first input of the address switch, the second input of which is connected to the educational information playback unit, and the output to the address register input.

A device for training and monitoring students' knowledge is shown schematically in the drawing and contains a response input block 1, connected to response comparison block 2 and memory block 3 connected to address register 4, educational information playback block 5 and address comparison block 6 that is connected to the address register 4, the playback unit for the educational information 5, and the attribute detection unit 7 connected to the response comparison unit 2, the educational information playback unit 5 and the control unit 8, which is connected to the address register 4, recording unit 9 and the block comparing responses 2 connected to the teaching information reproducing unit 5 which is connected to the address register 4 and. the registration unit 9, the random signal generator 10 connected to the counter 11, which is connected to the first input of the address switch 12, the second input of which is connected to the educational information playback unit 5, and the output to the input of the address register 4.

The response input block 1 consists of alphanumeric response input buttons, a decoder, response memorization triggers and a tape starting relay (not shown).

The storage unit 3 contains a storage medium on a film with information frames and control codes printed on it and a reversible tape drive mechanism (not shown).

The educational information playback unit 5 consists of photo-electric amplifiers of the same type that convert a photosignal into electrical impulses and amplify them (not shown in the drawing).

A recording unit 9 includes an error counter with a coincidence circuit at the counting input, a decryption | p and indicator indicator lights (not shown in the drawing).

A device for training and monitoring students' knowledge works as follows.

After entering the learning response, block 1 issues a response code and the calculator 13 issues a triggering signal of the tape mechanism to the memory block 3. During the motion of the film, the control codes pass by the photosensors of the playback unit 5, are read, amplified and fed to the calculator 13, which Based on the response code and the codes read from the film, it searches for the desired frame. Codes

are read sequentially while the film is moving. The response code goes to the response comparison unit 2. This unit receives signals from the playback unit 5 from photoelectric amplifiers, which read the codes of possible answers and the "mandatory comparison" bit, and from the definition unit 7, control signals for reading one or another type are received. codes.

In the initial state, the calculator 13

 responds only to possible response codes and control codes. When comparing the response code with the possible response code and in the presence of a signal from block 8, block 2 outputs a comparison signal to control block 8.

If none of the provided codes of possible answers were compared with the response code (the student answered in a prescribed manner), then the code will come in, which contains the bit "a mandatory comparison" and when reading such a code, unit 2 issues

0 comparison signal to control unit 8.

Signal determination unit 7 receives signals from the bits of the playback unit 5, which are occupied by distinctive features, and from block 7, authorizing signals are received about the presence of a code type to the response comparison unit 2, or to the control unit 8, or to the address comparison unit 6, depending on on the type of code.

The control unit 8 on a signal from block 2 produces a memory of the presence of comparison

0 response code and possible response code and generates a short-term signal to write an error to the recording unit 9, and if the code being compared is coded with the wrong code, which is sent to the recording unit 9 from the block, then if two signals match, the 9 block detects and displays an error .

After storing the comparison signal of the possible response code with the response code Kodo by block 8, the calculator 13 only responds to the next type of codes. The first incoming code of the next type causes the appearance of a signal from the block, 7 to block 8, which generates an enabling signal to write the address of the next

5 frames in the address register 4. Part of the address (several bits) of the next frame from playback unit 5 enters address register 4 directly, and the other part of the address (remaining bits) from playback unit 5 enters address register 4 through switch 12. When connecting register 4 by switch 12 to the playback unit, the device will operate in the "learning" mode and all the address bits of the next frame go to address register 4 from the playback unit 5. In another state of the switch 12, part of the address bits goes to reg page address 4 from the outputs of the random sample of the counter 11, which counts the pulses from the generator 10 and the random signal has the time recording random code. This is the control mode.

According to the signal from block 8, address register 4 writes the address of the next frame to address register 4 either completely from playback unit 5, or records part of the address of the next frame from playback unit 5, and writes other part of the address from counter 11, depending on the state of switch 12 The address of the next frame is remembered for the duration of the next frame search.

The block 8 memorizes the issuance of the enabling signal and does not give repeated signals, and the calculator 13 further reacts only to the codes of the next type. Part of the address of the next frame arriving in addition to the switch 12, contains the direction of movement of the reverse movement and, if the necessary frame is in the direction opposite to the initial direction of motion of the film, address register 4 generates a signal of the reverse in the memory block 3, in which the direction of movement film reversed.

The address comparison unit 6 performs a bitwise comparison of the address of the next frame, coming from address register 4 and the frame code, coming from playback unit 5, in the presence of a resolving signal from feature detection unit 7. When a bit comparison is performed, unit 7 outputs a signal to stop the tape. mechanism in memory block 3.

The frame search cycle can be without comparing the response code. When organizing a linear program section, the transition from frame to frame can be accomplished using a single code, in which the frame code is all zeros, since in the initial state the address register 4 is in the zero state when reading the code of this type with zero code the frame is compared with the zero address; block 7 issues a signal about the presence of a code feature in block 6, which generates a signal for stopping the tape drive mechanism, which is fed to the memory block 3.

The use of this device allows you to increase the functionality

devices, namely to use the same device for training and control with a random sample of frames. This eliminates the need to have several types of devices in one audience, some of which are intended for training, and others for control.

At the same time, the control is carried out more qualitatively, since each student receives one frame at random from each frame zone. And when forming zones by topics and sections, frame selection is not included in all topics or sections.
