Description

one

The invention relates to the technical means of programmed learning and the quality control of learning and can be used in all areas of education where programmed control is possible.

A device is known that contains a block for inputting answers, an encoder, a switch for the number of questions, a block for registering answers 11

The disadvantage of this device is that it does not take into account the difference in control questions because of its complexity and importance for the learning of the material being studied.

The closest to the present invention is a device consisting of a response input block, a counter, a decoder, a knowledge assessment indicator, a logical part having a weights assignment scheme to answers executed on the master oscillator associated with serially connected counting triggers, and the output is with inputs elements of the scheme of temporary selection 2.

The drawback of the device is complexity due to the large number of elements, which leads to a decrease in its reliability.

The purpose of the invention is to improve the accuracy of control and simplify the device.

The goal is achieved. In addition, a known device for controlling students' knowledge, containing sequentially included

0 response input block, response coding block, question number switch and answer recorder, as well as series-connected counter, decoder and indicator, 5 sequentially connected pulse distributor and analog-code converter connected to the counter input and the output of the question number switch, and the output of the response recorder is connected to the input of the pulse distributor.

The drawing shows a functional diagram of the device for monitoring students' knowledge.

The device contains a block 1 input answers, block 2 coding answers, switch 3 numbers of questions, recorder 4 answers, distributor 5 pulses, converter (caller 6 analog-code, counter 7,

decoder 8, indicator 9 (for the assessment of knowledge). The transducer circuit b (response weights in the number of pulses) contains the elements H / tO, the number of second is equal to the number of outputs of the distributor 5, and the element OR 11 ,.

Block 1 performs production; the response signal, which after 2, the switch, .Л, goes to registrar 4, which may contain both registrars of correct and incorrect answers or only registrars of correct answers.

If the answer was made correctly, then from the registrar 4 (from the registrars of the correct answers) a signal is sent to the input of the distributor 5. The number of outputs of the distributor 5 is equal to the maximum weight of the answer to any question, for example, b. The outputs of the distributor 5 are connected to the inputs of the elements And 10.

The inputs of the And 10 elements are also connected to a switch of 3 question numbers.

The outputs of the elements And 10 are connected through the element OR 11 with the counter 7. The elements And 10 and the element OR 11 form a converter that converts the weights of the answers into a number of pulses. The counter 7 can be performed, for example, on counting triggers.

The diode decoder 8 is made matrix and converts the result of the assessment of knowledge from binary to decimal number system. Indicator 9. (assessment of knowledge) performed on the lamps.

The device has a reset button.

The device works as follows.

A student is offered a control ticket, for example, from the ten questions of Sov. Each question is assigned a certain number of units, for example, the most important and complex questions of 6 units. The remaining questions, depending on their complexity and importance, from 1 to 5 units. Thus, a student's account for the correct answers to all ten questions of a ticket is the maximum number of units, for example, fifty. Forty-four units, for example, it is considered to be 4 minimum for a positive assessment.

The device works as follows when answering one question of the ticket.

When a response is entered into block 1, a signal is received, which through block 2 and switch 3 enters recorder 4. If the answer was made correctly, then a signal to start distributor 5 pulses is received from recorder 4. It produces 6 pulses that arrive at the elements And 10.

Only pulses are transmitted to the element OR 11, the elements and 10 of which have permission from the switch 3 question numbers. For example, go through five pulses. These pulses through the element OR 11 arrive at the counter 7, which counts the pulses in the binary system. The result of the calculation after the decoder 8 enters the indicator 9 (for knowledge assessment).

The device works in a similar way when answering other questions of the ticket.

Indicator 9 indicates the total number of units received by the students. However, the decoder 8 can be constructed in such a way that the indicator 9 will evaluate the answers in the five-point system.

The proposed scheme has pros. The first design, greater reliability, increased objectivity of the assessment of knowledge, since the scales of answers to questions are not twice as different, and a more accurate balance between the importance and complexity of the questions can be worked out.
