Abstract

The invention of automation and computing is intended for automated knowledge control for all types of class-group activities with a selective form of answers. It allows you to control the result of answers on the Console .., 0 teacher on the number of errors, and on the student's console - on the numbers of questions answered incorrectly. Such monitoring is carried out by connecting the teacher’s console to the registrar of question number 9 of the student’s console through a resistive adder 10. The indicators of unit 9 are connected via switch 8 to the outputs of the questions counter 1 and to the outputs of the result register 6 (location 011; ibok). Fixing the end of answers to questions is accomplished by connecting the high-order bit of register 6 to the control input of switch 8, to the recorder 7 of the control end (answers to all questions) and to the input of the driver 5 of the end of response pulses to the question through a resistor (matching element) of the block 3 input answers.

Description

The invention relates to technical means of programmed training and can be used for all forms of individual and group knowledge control with a selective form of answers.

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

The drawing shows the structure of the device.

The device contains a counter of 1 questions, a coding block 2 (answers), a block 3 for entering answers, a shaper 4 of the O1IB signal (trigger), a shaper 5 impulses of the end of the answer to the question, a result register 6, a registrar 7 of the control end

When power is turned on on bus 13 of block 3, due to the delay elements, the rise of the leading edge is delayed, the potential O is applied to the input of the imaging unit 4, and its trigger switches to the position O. Shaper 5 is also prepared for operation from this signal.

After reaching the signal on the capacitor of the power supply unit 3, the shaper 5 is triggered, the counter I switches to the first question, and the register 6 records information for the first digit. The information is entered into the register 6 due to the potential received at its input from the driver 4 , and the signal received (answers to all questions), switch 8, re- (5 ™ input from the driver 5. From the output

the hysteresor 9 answers, the adder 10 (the O1 number for the teacher’s progress indicator), the output 11 to send a signal to the teacher’s end of answers to the teacher, the output 12, which provides information on the number of errors to the teacher’s progress indicator, negative 13, zero 14 and positive 15 power buses, inputs 16 and 17 of the installation in the "O.

From counter I, an indication of the number of the answered question is turned on. Counter 1 also performs the encoding of answers through block 2 by connecting the output of the answered question to one of the inputs of block 3. The output of block 3 has its own information input connected to driver 4, to the setup input of which the output of generator 5 is connected, the signal from the output of generator 5 also switches counter 1 to the next question. The corresponding inputs of the register 6 are connected to the output m of form mounts 4 and 5.

The output of the higher bit of register 6 is connected: to the registrar 7 (with the indicator of the end of answers to all questions), to the control of the com- munor of the switch 8, to the input of block 3. From the registrar 7, after the end of the answers to all the questions, on exit 11, the end of response signal is given. The switch 8 connects the indicators of the recorder 9 to the outputs of the register 6 after the end of the responses, and the number of errors is output from the adder 10 to the output 12. From the output of register 6, the operation of the former 5 is also blocked after answering all the questions.

A device for learning to control the knowledge of students works as follows.

Power is supplied to the device, at the moment of which the signal "Set to O" is generated at inputs 16, 17. With this signal the device is set to its original position. In counter 1, this signal is set to the zero question. Before the beginning of the work, before supplying power, by means of block 2, the teacher codes the questions by connecting the outputs of counter 1 to the inputs of block 3 ..

the most significant bit of register 6 is zero and goes to the input of the recorder 7 and the input of the commutator 8. From this potential, the commutator 8 connects the inputs of the counter 1 to the recorder's inputs. This indicates the number of the answered question. When the potential “1 at the output of the register 6, the switch 8 connects to the indicators of the recorder 9 the outputs of the controller 6.

The student answers the first question, one of the contacts of block 3 introduces the correct, in his opinion, answer. If the answer is correct, then the resistor at the input of block 3 through the contacts of blocks 2 and 3 is connected to the output of counter 1 corresponding to the first question (all other outputs of counter I have a low potential). In this case, the shaper 4 CBcje state does not change. When the response input contact is released in block 3, it generates a signal of shaping. 5, with which counter 1 switches to the second question, and in register 35, information is shifted to the third digit.

The student answers the third question. If the student makes a mistake, the resistor at the input of block 3 through the contacts of this block and block 2 is connected to the output of counter 1, which has a low potential. By reducing the potential at the resistor of the block 3, the shaper 4 is switched, from its output to the input of the register 6 the potential "Error" is applied.

When the response input contact is released in block 3, a signal is generated at the output of shaper 5, by which counter 1 switches to the third question, shaper 4 is set to the initial state, and in register 6 information is shifted from the third bit to the fourth, and from the first to second.

After answering the last question, for example, the tenth, in register 6 in the senior (eleventh) discharge, the signal "1 appears, which turns on the indication in the registrar 7 from the source to the bus 15, and at output 11 the teacher receives the end signal Trainee answers to all questions.

The signal from the crapdiero register bit 6 is also fed to the input of the switch 8, which switches and connects the outputs of register 6 to the inputs of the recorder 9.

Indicators with question numbers are turned on in which the student made a mistake, while at output 12 the teacher will receive information about the number 01 through the adder 10 from the recorder 9. This signal also goes through the resistor 3 to the driver shaper 5. At the same time, the driver shuts off 5, and hence the entire device.

Thus, the proposed technical solution pacHJUpJiei didactic opportunities due to the replacement of the answers of students according to the number of 01 on the teacher’s console and in the place of the teacher on the consoles of students. Such a control allows us to make a differentiated assessment and reveal the material that the student does not know, i.e. the device can be used for one of the training objectives.

In addition, the device’s inmability () is determined by using the same indicators to control the number of the answered question and the number of questions that were answered incorrectly.
