(54) TRAINING DEVICE

The invention relates to automation and computing and can be used in various educational institutions for training. A device for training and monitoring is known, comprising a response input unit connected to an answer comparison unit and a memory unit connected to an address register, a playback unit yJ of information and an address comparison unit which is connected to the address register, an educational information playback unit and a feature determination unit connected to an answer comparison unit, a training information reproduction unit and a control unit that is connected to the address register, a registration unit and a comparison unit quick advice unit connected to the information reproducing Study, which is connected to the register address and register unit connected to the pul.tom teacher, school block determining process stages coupled to the outputs of educational information reproducing unit and the comparator to the input address and the remote teacher. This device allows teaching according to extensive programs, as well as recording and issuing to the teacher information about the number of stages passed by students and the number of errors they made I. The disadvantage of this device is the inability to teach students according to programs that allow them to form knowledge of a certain predetermined process of learning level by sections (stages) of training. The closest technical solution to the proposed adaptive training device comprises a controlled overhead projector, a screen, a photosensor unit, an input unit, a logic unit, an evaluation unit, a display unit, a communication unit with a computer, and a decoder. The device projector projects the training information to the screen, and the control codes onto the photosensor unit. The logical unit is connected to the overhead projector, the input unit, the evaluation unit, the display unit, the communication unit with the calculator and the decoder associated with the communication unit, which is connected to the evaluation unit by the calculator. This device can work offline or in conjunction with a computer 2.

However, in a standalone mode, the device does not allow students to be trained in each stage of the programs at a predetermined level of knowledge acquisition within the stage. When using a computer, the cost of training increases dramatically. In the course of training, it is necessary to establish at each stage the level of the quality of learning that a student must achieve.

The learning process can be thought of as a successive ascent to certain levels. Such a discrete representation of a continuous process makes it possible to quite definitely define and diagnose its course and the quality of students' knowledge. There are, for example, four levels of learning, distinguished, based on the requirement of distinguishability: knowledge of acquaintances, knowledge-copies, knowledge-skills and knowledge-transformations. It is obvious that the formation of knowledge on the division (structure elements) of educational material can be carried out at different levels depending on the requirements of the training program or the current requirements for different groups of students, different specialties, etc. At the same time, it is necessary to have a training program that allows to form knowledge in various sections at any level, and to promptly set the requirements for the knowledge being formulated by the teacher. The reason for this is the inability to set the required level of knowledge acquisition by students in sections of the material and train them in the appropriate program for this level.

The purpose of the invention is to expand the didactic possibilities and simplify the device.

This goal is achieved by the fact that a device containing a teacher’s console, a control, evaluation and display unit and a sequentially connected response input unit, a memory unit, a training information reproducing unit and a learning process definition unit connected to the first output of the control unit are connected to the second the third and fourth outputs of which are connected to the inputs of the memory block, indication and evaluation, respectively, the first and second inputs of the control unit are connected respectively to the output of the response input unit and the first you Odom reproducing unit training information included administered sequentially switch and the comparison unit, soedinennsh output and input respectively to the third input of the control unit and the second output of the reproducing educational information.

Moreover, the comparison unit contains sequentially included decoder, AND elements and OR element.

The switch contains the AND elements connected in series and the OR element.

FIG. 1 shows a block diagram of the proposed device; in fig. 2 is a block diagram of a comparison (mastering level) and switch (mastering level code).

The training device (Fig. 1) contains a response input block 1 connected to memory block 2 and control block 3 connected to display unit 4, evaluation unit 5, learning process step determination block 6 and memory block 2 connected to block 7 reproducing learning information connected to block 3, block 8 of comparison and block b connected to switch 9 connected to block 8 of comparison connected to block 3, and

the teacher’s console 10 connected to the switch 9. Blocks 1-7 and 10 are not structurally different from the corresponding blocks of similar devices.

The response input unit 1 contains switching elements, memory elements and the start relay of the unit 2. The memory unit 2 contains an automatic overhead projector and an educational information carrier on a film with frames and control codes printed on it. Unit 3 controls the overhead projectors of unit 2, unit 4, unit 5 and unit 6.

The block senses the response code of the student from block 1, and from block 2 senses the control codes printed on the film. After comparing the response code with one

from the control codes, block 3 stops the overhead projector of block 2. Block 3 sends an error signal or the correct answer to blocks 4 and 5, the first to indicate the correctness (irregularity) of its actions, the second registers

the student’s actions and scores according to a predetermined criterion. Block 3 also determines the beginning of the next stage and controls the state of block 5 of the stages of the educational process.

Block 6 contains a counter, the state of which corresponds to the number of this stage of the program, by which the student is currently studying. Block 7 consists of a screen and a block of photoelectric sensors that read the control codes for the film.

Comparison unit 8 (Fig. 2) contains a decipheror 11 (mastering level codes), elements AND 12, and an OR element 13. Switch 9 (mastering level code codes) consists of AND elements 14 and OR elements 15. The console 10 contains switching elements for each stage according to the number of levels of learning (for example, four keys for each stage).

The control codes of the film, except for the address codes, the frame, and the auxiliary control codes, contain the bit of the stage. The length of the program between the two coded bits of the stage contains a certain amount of educational material being studied. The control codes also contain a code for the level of learning. The sections of the program within the stage, limited by knowledge level codes, characterize all the ascent variants according to the levels of learning up to this one (the segments in this case contain material corresponding to 1, 1-2, 1-2-3, 1 -2-3-4 levels) or characterize each level of learning (segments contain material corresponding to levels 1, 2, 3, and 4). In both cases, up to four segments of the program can be located within each stage. In the first case, you should choose one of the segments, in the second - sequentially from the first to the final. The device works as follows. The teacher, before starting the training of students using the console 10, introduces requirements to the level of learners' formed knowledge (their quality) for each stage of the program, which includes a certain part (section) of educational material. . For example, if in the 2nd stage one should reach the 3rd level, then the teacher commutes 1, 2 and 3 keys of the four with the keys corresponding to the 2nd stage. Initially, the counter of block 6 is in the state that characterizes the first stage of training. The code of this state enters the switch 9, which transmits to block 8 the code of that level of mastering the first stage, which corresponds to the level of mastering of the first stage set by the teacher. If the student is trained in the first stage of the program, block 6 provides the enabling signal to the inputs, for example, the upper four elements of the scheme And 14, while studying the second stage to the inputs of the other four elements And 14, when teaching them the last stage to the inputs of the lower four elements AND 14 and block 9. The first element OR 15 receives signals from the first elements AND 14 of each four elements AND 14, the second signals from the second elements, the third from the third, the fourth from the last elements of AND 14 of each of the four elements and 14. At the exit element OR 15 is present that signal (s) defining a segment (segments) of the selected program. The code coming from the elements And 15, can contain one unit, which corresponds to a simple choice of the desired segment from the stage, or contains several units, which corresponds to the sequential selection of each segment from the first to the desired. When learning, the student enters a response using block 1. The response code from block 1 is fed to block 3, and the signal of input-to-block 2 input to the overhead projector. The film codes pass by the photoelectric sensors of block 7, are read, amplified and fed to blocks 3, 6 and 8 of the device. In block 8, the code for a given mastering level and the mastering level codes on a tape are compared. Block 3 supplies the memory block 2 with a stop projector signal not only if block 3 compares the response code of the student (or error code, time code) with a specific film code (as in known devices), but also when there is a signal; a predetermined digestion level code with a certain film code passing from block 8 to block 3. In block 8, the code of the digestion level after passing through the decoder 11 enters one of the elements And 12 corresponding to the given program segment. If there is a single signal at the output of the corresponding element AND 15, the element AND 12 sends a signal through OR 13 to block 3 to stop the tape drive. After stopping the overhead projector, block 4 indicates the correctness of its actions by the signal from block 3, and block 5 counts the number of correct (incorrect) answers from the student and evaluates the control signal from block 3. of the material from the signal from block 7 and block 3, block 6 enters a state characterizing the next stage of training, and switch 9 transmits to block 8 a code corresponding to the teacher’s knowledge level s next phase. In training, the ascent according to the levels of learning is carried out sequentially; therefore, training at each subsequent level includes training at all previous levels. Thus, when forming activities according to the pattern corresponding to the third level of mastering, students must first learn the first and second levels. up to a certain level, or contain only sequentially located material (one branch), corresponding to the successive ascent of the four levels of learning. In the first case, the assignment of the level of mastering by the stage requires the choice of one of four subprograms. In the second case, the assignment of the level of mastering by the stage requires the passage of a certain number of segments of the stage, which corresponds to a given level of mastering. If in block 10, the achieved level is set by switching only one key corresponding to the achieved level, then in the second case, block 8 performs masterings with all film codes bounding the segments within the stage that correspond to all the previous and specified level of mastering. For example, when assigning the 3rd level of learning, block 8 compares the codes corresponding to the 1st, 2nd and 3rd levels with the given code corresponding to the 3rd level of learning.

The proposed device allows students to teach material at various levels. This level of student knowledge should be achieved during training. Levels of learning, characterized by distinctiveness, are set by the teacher at each stage of training. These levels can be, for example, four.

The device allows you to choose at each stage the training program, which corresponds to the mastering level set by the teacher, while the learning process is characterized by successive ascent from low levels of mastering to high, up to the level set. Such a training organization allows, using one program, to train different contingents of students, whose training content varies depending on certain requirements. At the same time, the teacher can flexibly and quickly change the required level of learning of students within each stage, and control the content of the training.
