(54) AUTOMATED CLASS FOR TRAINING AND CONTROL OF KNOWLEDGE TRAINING

The invention relates to the field of automation and computer technology, in particular in the field of educational systems: Those built on the basis of computers, and is intended for programmed training and control of students' knowledge in various educational institutions.

An automated class Dl is known, having remote consoles containing a keyboard and connected via switches to a comparison relay and indication and recording nodes of student responses.

An automated class r2j is known, containing appropriately connected central logic unit with a teacher's control unit, by trainees, a control board, a unit for issuing educational information, a unit for issuing commands, a switchboard with a clock program mechanism, a group accumulator of responses, a program block for setting response codes ,, software mechanisms, response correction blocks, containing threshold amplifiers and a series of resistances connected to the input circuit of the threshold element and the shun pins of input taps keys.

The disadvantages of the known devices are narrow specialization; limited functionality, lack of processing control results and the presence of mechanical components. This reduces their reliability and increases the level of schum in the classroom, which distracts the attention of students.

The closest to the technical essence of the invention is an automated class 13, containing associated, respectively, student consoles, including a response input block, a status trigger and a response register, a memory block, a response coder, a computer, an interrupt control unit, an OR circuit, a block switch control, switch boards and input character counter. Such an automated class has limited functionality due to the lack of a programmed learning mode, and also requires a large amount of information to exchange with a computer in interrupt mode. The aim of the invention is to expand the didactic possibilities and simplify the device. This goal is achieved by the fact that in an automated class containing a software control unit, connected by the first input to the output of the interrupt control unit, the learning console, including display blocks, response input blocks, connected by outputs to the first inputs of the corresponding response memory blocks and learning states. process, the second inputs of which are connected to the outputs of the corresponding pulse shapers, a block for generating signals for polling the states of the consoles, a block of the OR elements, the assignment code distributor are entered: task memory locks and comparison blocks, the inputs of which are connected to the outputs of the corresponding response input and response memory blocks and the first outputs of the corresponding task memory blocks, and the outputs with the first inputs of the OR element block whose output is connected to the second input of the software block control and the second input - to the output of the signal conditioning unit of the consoles, also connected to the input of the interrupt control unit and to the first input of the assignment code distributor whose second input is connected to the output of the program block many controls, and codes to the first inputs of the task memory blocks, the second and third outputs of which are connected to the inputs of the corresponding display units and drivers of control pulses and the second inputs to the outputs of the corresponding response input blocks. The inputs of the signal generation unit for polling the states of the consoles are connected to the outputs of the memory blocks of the learning process. In the drawing is given the structural scheme of the proposed class. It contains consoles 1 trainees, blocks 2 input answers, blocks 3 04 of the memory of states of the educational process, 4 memories of the answer, blocks 5 of comparison, blocks 6 of the memory of the task, blocks 7 of the display, shapers 8 of control pulses, block 9 of formation of signals polling the states of the consoles, distributor 10 task codes, block 11 of elements OR, block 12 of controlling interruptions, block 13 of software control made, for example, on the basis of a standard computer. Automated class for training and knowledge control of students works as follows. The automated class provides programmed training according to the program recorded in block 13. At the beginning of a lesson from block 13, the individual training program enters the consoles 1 through block 13, which are recorded in block 6. Each block 6 has three zones in which it is recorded the following information: in the first zone, the training dose of information and the control task, in the second zone, the answer to the control task, and in the third zone, the end-of-message marker (the unit in the last oasr pe). At the time of the Mark: Era replacement, the shaper 8 generates a reset pulse, which enters blocks 3 and 4, according to the created voltage increment, which sets 3 into the zero-state state. The information recorded in the first zone of block 6 is displayed to the learner using the indicator panel of block 7. The automated class allows you to work at a reasonable learning rate for each student. After assimilating the dose of information and analyzing the test task, the learner enters his answer using block 2 into block 4. After entering the answer, the learner sends a signal for the end of the answer, which from block 2 enters block 3, block 5 comparison and zero bits the third zone of blocks 6. When the discharge of the third zone of block 6 (marker) is reset to zero. Block 5 compares the response of the student recorded in block 4 and the response to the control task recorded in the second zone of block 6, and block 3 is translated into one state. Transferring unit 3 to a single state means that the first

The remote control i is ready to exchange information with block 13. Block 9 analyzes the readiness of all remote controls 1 in turn.

Upon detecting the console ready for exchange j, block 9 starts block 12, replacing switching in block 11. B, as a result, the state of block 5 of this console 1 is transferred to the information buses of block 13 and prepares the distribution limiter 10 for transmission of the new task After this interrupt processing, unit 13 receives from block 11 a signal about the result of this student’s response to the control task (single signal if the answer is correct and zero if not).

According to the tutorial, the block, block 13, through the distributor 10, writes a new task to this console 1, and if the learning process is over, information about the completion of the job with the message end marker.

In both cases, the post-clearance 25 of the marker to the third zone of block 6 is perceived by shaper 8 as a positive voltage drop, as a result, a single pulse is removed from the shaper 8 output, resetting block 4 and setting block 3 to the zero state.

Block 9 continues the polling cycle. At the end of the time allotted for the educational process, or when all students go through individual programs, block 13 finishes the training cycle.

The proposed automated class for teaching and controlling knowledge of 40 students allows expanding the functional possibilities by combining the teaching functions of a computer embedded in the program and controlling knowledge.
