Description

one

The invention relates to automation and computing, in particular, to technical means used to teach and control students' knowledge.

One of the known training devices comprises a projector, a screen, a photoelectric converter unit, a control code, a code for the frame number code and a marker code, a response input unit, a switch, a comparison circuit, a overhead projector control unit and a command input unit 1.

However, the device does not allow detecting fatigue of the student and changing the illumination of the screen depending on the accuracy of the student. (The closest technical solution to the present invention is a training device comprising an illuminator, an answer input unit connected to inputs of a calculator and a memory block, the output of which is connected to a playback unit connected to an input of a recording unit and a calculator connected to inputs of a memory block and registrations 2.

The disadvantages of this device is the lack of definition

fatigue factor in training on the Mass and the impossibility of changing the brightness of the illumination radiation depending on the fatigue of the student. WITH

by increasing the fatigue of the increasing screen illumination, it should be increased, since this improves the perception of information and increases the efficiency of training. The fatigue of the student should be assessed by the volume of acquired knowledge and by the time spent on the assimilation of this knowledge.

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

This goal is achieved in that the device containing the response input unit connected to the calculator and the educational information display unit, which is connected directly to the calculator and through the educational information reproducing unit, to the calculator and the registration unit connected to the calculator connected to the forwarder

control signals, an adaptive volume control unit of the displayed information is connected to the input of the training information presentation unit and to the outputs of the educational information playback unit, the computer and the control panel of the control signals.

FIG. 1 shows the scheme of the proposed device; Yig, 2 block adaptive. control the brightness of the displayed information

In the proposed training device (FIG. 1), the response input unit 1 is connected to the calculator 2 and the memory block 3 connected to the educational information reproduction block 4, which is connected to the registration block 5, the adaptive display information control b block and the calculator 2, which is connected to registration block 5, memory block 3 and block b, is assigned y with the illuminator 7, and in addition the input of the control signal generator 8 is connected to the calculator 2, and the output to block 6,

The response input block consists of alphanumeric response input buttons, a decoder, response memorization triggers, and a tape starting relay (not shown), Evaluator 2 is a logic device that, based on the student’s response and read from the film , controls the search for the next frame. The memory unit 3 contains the information carrier on the film with information frames and control codes printed on it, a projection-optical system and a reversible tape drive mechanism (not shown), the Educational information reproduction unit 4 consists of photo-electric amplifiers of the same type that convert photo-signals into electrically impulses and amplifying them. The registration unit 5 includes an error counter with a coincidence circuit at the counting input, a decoder and indicator lamps (not shown), the Illuminator 7 is designed to project information frames on the screen. The illuminator 7 and the memory unit 3 are combined in the educational information display unit 9.

Block 6 contains (FIG. 2) an AND element 10, an element 11 OR step, a finder 12 with a switch 13 and a transformer 14, the secondary winding of which contains terminals 15. The illuminator 7 is connected to the switch 13 and one of the outputs of the secondary winding of the transformer 14,

The proposed training device works as follows

After entering the learning response, the response input unit 1 supplies the response code to the transmitter 2 and sends a start signal to the tape mechanism in the memory unit 3. During the motion of the film, the control codes pass by the photosensors of the block 4, are read, amplified, and fed to the calculator 2, which, based on

response code and film codes search for the desired frame.

One of the control codes for a film contains a dose of information that characterizes a certain amount of information. the ny volume of the acquired educational information. The entire training program is divided into several subprograms with the same amount of educational information. After studying the next dose of information, the signal corresponding to the discharge dose of information from block 4 enters block 6, where it is recorded by the enabling signal that arrives at block 6 from calculator 2 only during the search for the desired frame, when the screen is visible, In block b, in addition, signals come from the imaging unit 8, which determine the learning time of the student. The output of signals from the imaging unit 8 is also performed on the permissive signal coming from the calculator 2 only during the search for the desired frame when the screen is visible. Block b, depending on the volume of the material studied and the time it was studied, evaluates the fatigue of the student and, on the basis of this estimate, changes the brightness of the illuminator 7,

If the student made a mistake when answering the test questions, then from block 4 the error signal will go to block 5 of registration and according to the enabling signal coming from calculator 2 to block 5, the latter will summarize and indicate an error.

If the required frame is found during the search for the next frame, then the COMPUTE slider 2 generates a signal to stop the tape drive mechanism in memory block 3.

After studying a certain dose of information, the signal corresponding to the discharge information dose from block 4 goes to element 10 I, and if there is an enable signal from calculator 2, this signal goes to the first input of element 11 OR, to the second input of which comes a signal from the imager 8, which determines student learning time. The output of the element 11 OR is connected to the stepping finder 12, which by switch 13 connects the leads 15 of the secondary winding of the transformer 14. 14, thereby increasing the filament voltage of the illuminator 7 and the screen illuminance. It should be noted that the screen illuminance changes only during the search for the required frame, which up is provided
