Description

I

The invention of the ognosigs to the field of learning tools and can be used in the control of students' knowledge, when the answer is selected from several proposed options.

A device for monitoring pupils' knowledge is known, comprising a teacher’s console with a response recorder, connected via a survey switch with student consoles, each of which contains response input elements l.

A disadvantage of the known device is that when you enter a response in decimal form, the number of input elements increases dramatically, and in addition, when a knowledge transfer is made, usually done in binary code, complex decoders are required. All this increases the complexity of the design of the device.

The purpose of the invention is to simplify the xy-y device operation.

This goal is achieved by the fact that the device contains magnetic chips, the student consoles contain diodes by the number of response input elements, and the response input elements are made in a reed switch located under the top cover of the student consoles, the first reed switch outputs are connected to the counting inputs of the response recorder, the second terminals of the reed switches of each of the consoles learning through the diodes are connected to the corresponding outputs of the interrogation switch, and the digitized colored marks are affixed on the upper cover of the learning consoles.

FIG. 1 presents a blesh diagram of the proposed device; in fig. 2 is an upward and downward control panel} in FIG. 3 the same cut. BB in FIG. 2; in fig. 4 scheme included in the input element and the diodes in each console.

The device contains a remote control 1 teacher with the registrar of answers (not shown) that is installed in it through whom. mutazsr 2. About 1phosa connected with kansdym from cults of 3 students, and their outputs are connected to counting inputs. 3ft On the top cover 4 of each remote control, 3 digitized tags 5 are put up, which for convenience of use can be made in the form of depressions, into which magnetic chip 6 is placed, and the response is entered. Under the upper section 4, there are elements for entering answers (reed switches) 7.8.9, 1O and diodes 11, which serve for isolation. The terminals 12, labeled G1-G4, reed switches are connected to the counting inputs of the register, and terminal 13 (G5) by means of expanding diodes 11, the second high-voltage reed switches 7-10 of each console, are connected to the corresponding outputs of the switch 2 interrogation. The device works as follows. The teacher will, in one form or another, ask a number of questions for students and give them some time to think about them. For example, selecting one correct answer to the questions posed in the form of a decimal digit, the student sets his chip 6 into one of the recesses 5 of his console 3, the digitization corresponds to the digit of his chosen answer. After the time allotted to think about the answers, the teacher turns on the power on his console 1 and via the switch 2 polling sends positive voltage pulses successively on the remote controller 1 students, At the moment of a polling pulse sending to terminal G5 of the console 3 learn-os from terminal 12 Г1-Г4 A parallel binary code is read into the counting inputs of the recorder in the form of pulses, the voltage corresponding to the decimal number of the cavity in which the magnetic chip 6 is installed. For example, if the magnetic chip 6 is installed en in the indentation 5 of the console 3 with re 4 digit, then the magnetic field from the chip 6 causes only the reed switch 1O to be triggered and the binary code read from the terminals G1-H4 corresponds to OO01, if the magnetic chip 6 is installed in the groove 5 of the console with the number 7, then its magnetic field will trigger the activation of the reed switches 7.8 and 10. The readable binary code will be equal to OSH. Thus, the proposed device, with the simplicity of the design of the consoles of the learners, makes it possible to significantly simplify the registrar's structure and reduce the number of wires connecting the consoles to each other. An apparatus for monitoring students' knowledge, comprising a teacher’s console with a response recorder, connected via a survey switch to student’s remotes: each of which contains response input elements, characterized in that, in order to simplify the device’s design, it contains magnetic chips; diodes according to the number of response input elements, and the response input elements are made in the form of reed switches placed under the upper lid of the learning consoles, with the first conclusions of the reed contacts associated with counters in odes registrar responses second terminals of each of the reed switches remotes uchaschihs through diodes associated with the respective interrogation switch outputs, as the top cover panels uchaschihs applied digitized colored label.
