Description

The invention relates to the field of> automation and computing, in particular to devices for monitoring students' knowledge, and can be used in various educational institutions.

A device is known for. control of students' knowledge, containing student and teacher control panels, elements for input and coding of answers, blocks of indication and analysis of answers (1).

However, this device has limited didactic capabilities due to the lack of automatic change of questions. one

The closest technical solution to the invention is a device for learning control of knowledge, containing a block for entering answers, a register of questions, a coding block, an error number counter, a response analyzer, indication, registration and control elements [2],

In the mode of self-control of knowledge 2

This device has limited didactic possibilities, since the student cannot find the right answer if he does not know it or is not sure of the correct2

answer, i.e. in the device (there is no reinforcement of answers. In addition, in the known device, the error analysis circuit and the response generator are connected to the output of the response input block, which complicates the device, since the schemes on active elements (tiratrons or transistors) are required to perform the error analysis and response functions. .

The purpose of the invention is the expansion of the didactic capabilities of the device.

This goal is achieved by the fact that in a known device that contains a response input block, 'connected to the question register and an answer comparison block, connected directly to the error counter, and through the response encoding block to the question register, connected to the display unit, which is connected to one of evaluation recorders connected to the control unit, two keys are entered, one of which is connected to the error counter and the response comparison unit, the other to the evaluation recorders and the response input unit.

The drawing shows a functional diagram of the device.

The device contains a register of 1 questions, block 2 of coding answers ί block 3 of entering answers, key 4, block 5 comparing answers, sensor 6 ³

errors, key 7, indication unit 8, evaluation recorders 9 and 10, switches 11 'and 12, control unit 13, buses 14, 15, 16 and 17.

"0

The question register 1 indicates the number of the answered question and, through the encoding of answers 2, connects the output of the answered question to one of the inputs of the answers input block 3, by means of which ¹³ answers are entered into the device.

The output of block 3 is connected to register 1, which switches to the next question when selecting the answer in block 3. Input block 3 input answers 20

connected to key 4, which turns off power from unit 3 when turning on evaluation signals ’'Passed' 'or' 'Did not pass *' and blocks the operation of register 1 when selecting answers. 25

Block 5 is connected to the inputs of block 3, which compares the signals of incorrect answers, the number of which is registered by the 6 error sensor including via key 7 re- ^ 0, the result of the answers “Not passed”. The display unit 8 includes the evaluation recorder 9 (signal “Passed-Graduated ¹ ”) and the signal.

Switch 11 turns off the recorders 9 and 10 and key 4 when operating in the “Self-control of knowledge” mode. Switch 12 is used to set to its original position when operating in the "Self-control of knowledge" mode.

A constant voltage is applied to the device power bus 14 when operating in the “Control” mode and pulsing in the “Self-control” mode.

On bus 15, signals are sent for the “Self Check” and 45 '' Exam ' ¹ operating modes. Tires 16 and 17 are used to display the result of responses and signals '' Passed-Graduated '',

'' Did not pass-Error ''. '

Device for monitoring knowledge dd students works as follows.

In the “Control” mode, a constant voltage is applied to the bus 14 of the block 13. On the bus 15, the signals do not give ^SJ · 55

In register 1 indicates the number '' 1 ’’, the number of the first question. The output of the first question from register 1 through block 2 is connected to one of the outputs of block 3 of the input of answers, while only one of these outputs receives a signal (potential). The learner answers the question by choosing the correct answer number from one of the buttons of block 3. If the answer is correct, then the signal / potential from key 4 through the pressed

* l

the answer button arrives at the output of block 2, which has the same signal (potential) from the first question.

Block 5 does not respond to these signals. When the button of the selected block 3 response is released, the signal goes to register 1 and it switches to the second question.

If the answer is incorrect, then the signal (potential) from block 3 when entering the answer is allocated by block 5, passes to the input of sensor 6, where an error is recorded.

When the answer button of the block 3 is released, register 1 switches to the 3rd question, etc.

If the number of errors is greater than the allowable number, then the sensor 6 turns on the key 7.

When this key 4 is turned, food is removed from the block 3 and block Xia further work register 1 and 6. The sensor 10 indicates evaluation logger 'Not passed'', such an assessment is issued on bus 17. When the switch 12''Reset' ¹ Do not turn off the evaluation of "Not passed" and key 4 does not occur, as they are powered.

If the student answers the questions correctly or has made the number of errors, "less than the number allowed, then after answering the last question, the display unit 8 is turned on and the registrar 9 is turned on (" Passed ").

In the * 'Self-control' mode (training), the operation of the device is as follows.

A pulsating voltage is applied to the outputs of block 13; a signal for the “Learning” operating mode is sent to the bus 15. The student answers the questions in the same way as in the “Control ¹ ” mode.

If the answer is incorrect, the d ---- key 7 is turned on, the “Error” signal is displayed by the registrar 10, and the key 7 is turned off, by turning off which the switching of register 1 to the next question is blocked. Learned by the switch 11 turns off the recorder 10, the key 4, the key 7 and again answers the same question. After the correct answer, register 1 switches to the next question, etc.

After answering the last question, block 8 and registrar 9 are activated - “Graduated”.

In the “Simulator” mode of operation, pulsating voltage is applied to the input of block 13, Bus 15 is turned off (no signals are sent to it).

The student answers the questions in the same way as in the “Control” mode. If the trainee received the grade “Did not pass” ·, he sets the device to its initial position by means of the switch 13 ”Reset” and then answers the questions again and so on until receiving the grade “Passed”.

Thus, the proposed technical solution allows expanding the didactic capabilities of the device by providing the possibility of supporting the answers.
