Description

Fg / g. T

The invention relates to technical teaching aids and can be used in the educational process to increase the effectiveness of group learning and didactic research.

The aim of the invention is to increase speed by avoiding switching questions and simplifying the device by using fewer simpler, mostly passive, elements and reducing the number of communication lines between the teacher’s panel and the student’s panels while maintaining the didactic characteristics of the device.

Fig. 1 is a block diagram of a knowledge control device; Figure 2 is an example of a specific embodiment of the device.

The device for monitoring knowledge consists of a teacher’s console 1 containing a generator 2, an adder 3, a load element 4, a switchboard 5 of the control panels, filters 6 of the first group, indicators 7 of the control of answers, communication lines 8, and control panels of 9 students each coding - inputting blocks 10, filters 11 of the second group, and indicators 12 for correct answers.

A device for controlling knowledge operates as follows.

Preliminarily, in the consoles of 9 grandchildren, M tickets are set for M each, containing one question and several answer options, one of which is correct. By means of the encoding-input block 10, the correct answers for each question are encoded. In the process of preparation, the trainees, by means of the encoding-input response block 10, enter the supposed correct answers. In the control process, the teacher through the switch 5 panels connects through the corresponding communication line 8 one of the panels 9 of the trainees, thereby providing the possibility of passing currents of all frequencies simultaneously from the generator 2 through the adder 3, the load element 4, the switch 5 panels, line 8 St. zi and blocks 10 encoding-input answers, filters 11 of the second group, indicators 12 for the correct answers of the selected console 9 trainees. If all the answers are incorrect, then the encoding-input response blocks 10 are in a non-conductive state and all indicators 12 of correct answers are not turned on. In this case, the current does not pass through the aforementioned circuit, the voltage drop on the load element 4 does not occur, the potential of all frequencies at the inputs of the filters of the first group is high, currents of all frequencies pass along the corresponding parallel. For example, the chains and indicators 7 for monitoring responses are in the on state. If any answer is correct, then the corresponding coding-input response block 10 appears to be in a conducting state and through it a current is generated at the frequency to which the corresponding filter 11 of the second group is tuned. This current turns on the indicator 12 of the correctness of the response and forms a voltage drop on the load element 4, due to which the potential of this frequency decreases at the inputs of the filters of the first group b, the current through the corresponding filter decreases and the indicator 7 of the response control turns off. With other combinations of right and wrong answers, the device works in a similar way.

A device for controlling knowledge is performed, for example, as shown in Fig. 2. Generator 2 at M of different frequencies spaced into intervals corresponding to sufficient attenuation of neighboring frequencies by filters 6 of the first group and 11 of the second group is performed on an arbitrary element base, e.g., K118UN1, using sequential oscillatory circuits and, possibly, additional buffer stages (5). The adder 3 and the load element 4 are made on resistors 3., 4. Comm: tator 5 remotes made on the switch in one direction and the number of positions equal to the number of remotes 9 trainees. Filters 6 and 11 are made on successive LG oscillatory circuits 15, and resistors 14, 16 serve to eliminate the possibility of exciting and adjusting the brightness of the response indicators 7 and response indicators 12 made on indicator lamps 17 of any type, the consumption current of which corresponds to the output current generator 2. The blocks 10 for coding / inputting answers are made on two switches in one direction and the number of positions is equal to the number of answer options for one question. Thus, all elements of the device, with the exception of generator 2, are implemented on passive elements, and the oscillatory circuits 15 are unified for blocks 2, 6 and 11.

The proposed device for controlling knowledge allows to increase the speed by M times due to the automation of the operation of selecting questions, is simpler due to the smaller number of elements and the ability to replace the main part from active to passive and by reducing the number of communication lines to each remote control of students. In addition, the proposed device has 2 times

reduced maximum energy consumption due to the simultaneous illumination of no more than M indicators on the remote controls of the teacher and student.
