The disadvantage of this device is that it only fixes the wrong answers, but the teacher needs to know what caused this wrong answer.

A wrong answer to the question does not indicate a poor study of this topic. It often happens that the reason for this is the ignorance of the previous topic on which this topic is based, and the impossibility of a detailed study of this topic is already a consequence, and not the reason for the wrong answer to a question.

To answer a question, you need to know several training sections, i.e. In the process of wounding a task, the schoolchild is knocked down with a sequence of operations, each of which requires knowledge of one or several training topics, and it is not known, because of a lack of knowledge of a previously studied topic, the students answered incorrectly, because the wrong answer may be caused by ignorance of one or several training topics. .

This device does not allow an objective assessment of gaps in students' knowledge, which is caused by the lack of a block in it that stores a number of unexplored topics, which, with sufficient control, allow judging gaps in knowledge of a student with great certainty and correct the teacher's learning process.

The purpose of the invention is to increase the accuracy of the device and the reliability of the knowledge of students on the topics.

This goal is achieved by introducing into the known device (1) a block for analyzing the progress of the educational process, coupled with a block for reproducing reading information, a block for determining signs, a block for control and a block for registering.

Figure 1 shows the block diagram of the proposed device; figure 2 shows, four Tigg codes.

In the Proposed Training Device (FIG. 1), the response input unit 1 is connected to the response comparison unit 2 and the memory unit 3 connected to the playback unit 4, which is connected to the response comparison unit 2, the registration unit 5, the learning process analysis unit b , address register 7, address comparison block 8 and attribute determination unit 9 associated with analysis block b, address comparison block 8, control block 10 and response comparison block 2 connected to control block 10 connected to analysis block b, block 5 registration, and register 7 addresses connected to the memory unit 3 and the address comparison unit 8 associated with the memory unit 3, and in addition, the analysis unit 6 is connected to 6; the registration register 5 containing the registrars of the teacher 11 and the student 12.,

Before considering the operation of the device, it is necessary to consider film coding (Fig. 2).

In the proposed device, the program has four types of codes 13, 14, 15, 16 with various functions in controlling the operation of the device. Type 13 codes contain a possible response code 17, intended to be compared with a response code, a bit of a necessary comparison 18, necessary for an unconditional comparison with a response code, bit 19, intended for entering one penalty point in the recording unit 5 and a distinctive feature 20 capable of identifying type 13 code as a device. Distinguishing feature 20 contains such a combination of codes in its bits that is forbidden to codes of other types, for example, the third bit is light and the second bit is dark.

Type 14 codes containing the code of a possibly unexplored topic 21, which is the binary number of the counter in the block.

analysis b, which counts the probable number of errors made due to ignorance of this distinguishing feature 22 (the third bit from the bottom is dark and the second bit from the bottom is light) ...

Type 15 codes contain the address of the next frame (next frame 23, by which you need to search for the next frame and the hallmark 24 (second and third

0 bits below dark).

Type .16 codes contain a frame code of 25, which is a binary frame number and is intended to be compared with the address of the next frame and distinctive feature 26 (the second and third bits from the bottom are light).

In codes of all types, there is one service bit d-marker 27, designed to form a read enable signal

0 of the entire code and necessary so that the Informat is not read from the frames during the motion of the film. . ..

On film, the codes have 5 s: as follows. Next to the frame is a type code 16, intended to go to this frame, followed by a group of type codes 13,14,15, designed to go from

0 of this frame. Behind each type 13 code there is a few (or one) type 14 codes, followed by a type code 15 (not shown in Fig.). Blocks 2, b, 7, 8, 9, 10 are combined 5 nn into a calculation;

The proposed training device works as follows (figure 1)

After the response is entered, the response input unit 1 delivers the response code to the transmitter 28 and the start signal

 the tape mechanism in the memory block 3. During the motion of the film, the control codes pass by the photosensors of the reproducing unit 4, are read, amplified and fed

5 to the Shtiller 28, which, based on the response code and the codes read from the film, searches for the desired frame. . .. Codes are read sequentially.

0 during the motion of the film. The response code is received in block 2; This block is also received. the signals from the bits of the playback unit 4 from the photoelectric amplifiers, which read the codes of the possible responses and the discharge, are compared, and signals from the block 9 for determining the signs receive signals for reading type 15 codes.

In the initial state, the calculator

0 28 only responds to type 13 codes.

When bitwise comparing the response code with the code of the possible response and in the presence of a signal from block 9, block 2 injects a comparison signal into block 10

5 controls

If none of the possible response codes provided are compared with the response code (the student responded in an unexpected way), the type code 13 will come, which is the last one among the type 13 codes, which contains the required comparison, and when reading such a code, block 2 outputs a comparison signal to control unit 10.

Signal determination unit 9 receives signals from the bits of the playback unit 4, which are occupied by distinctive features, and from block 9, the permitting signals about the code type occur are received in the response comparison unit 2, if the read code is a type code 13, in the analysis block b if the code being read is type 14, in control block 10, if the code is type 15, and in address matching block 8, if it is type 16 code.

The control unit 10 by the signal from block 2 memorizes the presence of a comparison of the response code and the code of a possible answer and issues a short-term signal to write an error to the recording unit 5 and if the compared code of type 13 encodes the error incorrectly, which from block 4 is fed to registration 5 then, when two signals coincide, block 5 registers and indicates an error.

After the unit 10 memorizes the comparison signal of the possible response code with the response code, the transmitter 28 responds only to type 14 codes. When reading the type code 14, the attribute detecting unit 9 delivers the enabling signal to the analysis unit 6;

The code of the probably unexplored TeNM 21 in block b is decrypted, a signal is sent to the counter corresponding to this, probably unexplored topic, and if there are two enabling signals from block 9 and from block 10, the corresponding counter of block b will add one to its previous state. . .

A code of a possible answer may cost several codes of possibly unexplored topics, since it is not known due to the ignorance of which topic the students answered incorrectly, therefore all possible topics whose knowledge is necessary to answer this question will be listed, and each corresponding counter will add one to previous status. The contents of the counters are displayed on the recorder teacher 11.

The permissive signal from the control block 10 is necessary so that the addition of units in block b is made after comparing the code of the possible answer and before the arrival of the first type code 15.

After passing by block 4 of reproduction of all type 14 iodines related to the comparable possible answer code, a type code 15 will appear, containing the address of the next frame 23. This first type code 15 causes the signal from block 9 to block 10 to appear, and block 10 generates the enabling signal to write the address, the next frame IB register address 7. At this issue of the enabling signal

o from the control block 10 to the analysis block b is stopped and the enabling signal appears in the address register 7.

The next frame address contained in type code 14 and incoming

5 from block 4 to block 12, is written to the address register 7 and stored for the duration of the next frame search. The 10 block enable signal memorizes and alternate signals

0 does not issue, and the transmitter 28 in the future only responds to type 16 codes.

The address of the next frame contains the direction of movement of the reverse,

5 and if the required frame is located in the side opposite to the initial pressure of the film motion, the address register 7 sends a reverse signal to the memory block 3, along which the motion direction of the film is reversed.

Block 8. Comparison of addresses 7 produces a one-by-one comparison of the address of the next qyr, coming from the registrar with the addresses of the frame code, coming from the reproducing unit 4 in the presence of a razrabaakltsevogo signal from block 9 of the definition of signs (about the presence of type code 16). When the comparisons are degraded by block 8, a signal is issued

0 to stop the gaiter in memory block 3.

The use of the proposed device allows the teacher to more objectively reveal poorly studied

5 topics for students, since this device reveals knowledge

only current topics, but also knowledge. the topics on which the current topic is based. In view of that

0 that knowledge of a student's assessment is likely, it is necessary to carry out a sufficient number of controls, after which the teacher will collect the following information. For example,

5 Enania of topic number 1 is necessary for answering 5 questions, on these questions an average of 4.5 people answered correctly, and knowledge of topic No. 2 is necessary for answering 8 questions,

0 which were answered by an average of 3.2 people. This gives the right to assert that the topic t 1 is well understood by the students, and the topic I 2 is poorly understood. Knowledge of the learned and undigested topics

5 allows the teacher to improve the learning process and to devote more time to poorly studied topics, despite the fact that some topics were studied well before the current genes.
