TRAINING DEVICE

The invention relates to technical IMC tools designed to determine the level of operator training, operator selection and picking up homogeneous groups of operators. A device comprising an information output unit, a logic unit, an answer input unit, an indication unit, a task correlation calculation unit, and the correct solutions are known. control unit of the level of training of operators and evaluation unit. The joint implementation of the principles of the information theory of discriminating hypotheses and sequential analysis in a device makes it possible to evaluate the level of training of operators with a given reliability flj for the guaranteed number of training cycles. The drawback of the device is the restriction on the profile of the operators, the level of preparation of which is assessed. Thus, the device is applicable either to assess the knowledge of students or operators who perform a set of discrete operations without taking into account restrictions on the time of their performance. The closest to the proposed invention is a device comprising an information block, a logic block, an input block, an indication block, a block for calculating the mutual correlation of tasks and correct solutions, an evaluation block and a block for controlling the time for solving problems. Monitoring the level of operator training in the device is made according to the probability of correct and timely task solving by the operator. The device’s disadvantage is the assessment of the level of training only by the integral criterion without taking into account the data on the distribution of accuracy and time parameters of learning, which does not allow one to judge the physiological characteristics of the operator use a device for the psycho-physiological selection of operators and, especially, the assembly of homogeneous groups of operators. The purpose of the invention is to improve the accuracy of training. This goal is achieved by the fact that a known device containing a training information presentation unit is connected to a task time control unit, a task resolution control unit and an educational information analysis unit connected to a task time control unit and task accuracy. , the response input unit g to the display unit and the computation unit for the mutual correlation of the number of tasks and correct solutions, which is connected to the registration unit, the display unit and the control unit for the level of operators, Connected to the display and registration units, the response input unit is connected to the task time control units and task accuracy connected to the registration unit, a knowledge control parameter classification unit is introduced, connected to the registration unit and task time control units and the level of training of operators and the node containing the task time to solve problems, connected to one of the threshold elements and adders connected to the corresponding threshold elements, which through The appropriate counters are connected to a group of keys, coupled through respective delay elements with the input unit, but directly - with the output of the unit.

Such a constructive solution allows, in addition to an integral assessment of the level of operator training, on the likelihood of correct, timely and accurate decisions to obtain and print the distribution of accuracy and time characteristics of the activity by normative classes, as well as print the number of unexecuted in accuracy and time. tasks and all intermediate values of the accuracy and time of the task and observe on the display unit in each training cycle the number of cycles performed and the integral number of erroneous decisions at the present moment. All this significantly increases the completeness of control of the training level of operators and expands the functionality of the device.

FIG. 1 shows the composition of the blocks of the proposed device; in fig. 2 - functional block diagram of the knowledge control parameter classification; in fig. 3 - the registration block is functional.

The training device contains a block 1 of presentation of educational information, a block 2 of analysis of educational information, a block 3 for entering answers, a block 4 for indication, a block 5 for calculating mutual correlation of problems and correct decisions, a block 6 for controlling the level of operators, a block 7 for controlling the time for solving problems , unit 8 for controlling the accuracy of problem solving, unit 9 for registering, unit 10 for classifying knowledge control parameters, node 11 for specifying task time, threshold elements 12-14, adders 15 and 16, counters 17-20, delay elements 21-23, node 24 print and group key s 25-30.

The device works as follows.

The experimenter establishes in block 7 the admissible time for solving one problem, in block 8 it is admissible. accuracy, in block b - standards for training levels and maximum

number of tasks sufficient for

assessing the level of training with a given reliability, and in block 10 at node 11, the unit standard for the time to solve the problem. The subject receives information. About the task

5 through block 1 and enters its answers through block 3. Depending on the responses of the subject and the methodological information from block 1, block 2 generates presentation signals

0 of the following information by block 1, indication of the progress of the educational process by block 4, as well as a signal about the entered answer and correctness of the answer, which arrive at block 5. If the examinee has not solved the task within the allowed time with a given accuracy, then blocks 7 and 8 produce a signal into the block 2, which is perceived as an error response. Unit 5, depending on the signals from block 2, makes either a decision on the level of training or a decision on whether to continue testing. In the first case, the signal from the final assessment enters the display unit 4 and is displayed

there. In the second case, a signal is generated for the continuation of the test, which enters unit 2. From unit 5, unit 6 continuously receives signals about the number of tests

tasks and erroneous decisions. If the number of tasks is equal to the maximum, the block b determines the operator’s training level, which is displayed in block 4. The signal about the test person’s training level, which is generated either in block 5 or block 6, also goes to block 9 on print node 24, keys 29 and 30 and block 10, key 25 and elements 21-23.

Signals about the time to solve each task from block 7 and the accuracy of its solution from block 8 enter block 9 and block 10, threshold elements 12-14, time classification chains and the corresponding accuracy classification circuit elements (in Fig. 2 this circuit is not indicated ).

Block 10 works as follows.

The signal from node 11, which corresponds to the unit time standard for solving one task, arrives at the first input of element 12, to another input of which a signal is received about the time that the subject spent on

solution of the last problem. If the elapsed time is less or equal to the equivalent, then from element 12 a signal arrives at the counter 17. Otherwise, the signal corresponding to the standard time passes to the input of the adder 16, to the other input of which the same signal arrives directly from node 11. At the output of the sum of the torus 16, a signal is generated that is equal to a double standard, the actions to the input of element 13, to the other input of which, like element 12, receives a signal about the amount of time spent by the examinee to solve the problem from block 7. Thus, counters 17-20 sub ityvaets number of tasks which test ulozhils in single, double, triple and four fold and more the norm, respectively. The signals from these counters arrive at the input of the keys 25-28, which, after the arrival of the signal from blocks 5 or 6, stop opening tests with successively after a certain time, thanks to the pressure of elements 21-23. As a result, the signals from counters 17.-20, through the keys 29 and 30 successively arrive at the node 24, which also receives signals about the number of unsolved tasks in time and accuracy from the blocks 7 and B through the keys 29 and 30, which are opened with the signal The test of block 5 or block 6. Thus, node 24, after solving each task by the subjects, prints the time and accuracy of its solution, and after presenting all the tasks, the histogram of the task time distribution according to the standards and the histogram of the task accuracy distribution according to the norms tivam, as well as the number of outstanding accuracy and time zaschach. The positive effect of using the proposed device is to increase the completeness of control of the level of training of subjects by obtaining in addition to an integral assessment of the level of preparation of the tested parameters, the quality of their work in each control cycle and the distribution of these parameters (time of solution and accuracy of the problem), not normative classes existing on them, which makes it possible to analyze, based on the results of the device’s operation, objective reasons that determine one or another level of training, as well as psychophysiological portrait of the subject. All this expands the functionality of the device. It is possible to use the device in the selection of operators with certain psycho-physiological properties, picking up homogeneous groups and teams of operators. i The claims 1.
