Description

(54) A DEVICE FOR TRAINING AND CONTROL OF KNOWLEDGE OF PUPILS 380 answers, a control unit, drivers of a command for polling consoles 2, However, this device has a limited accuracy of inability to control knowledge and evaluate the results by training stages. The aim of the invention is to improve the accuracy of training. This is achieved by the fact that a memory block of learning steps and a match block connected with a memory block of steps are inserted into a known device containing the student consoles, connected to the switchboard of the consoles connected to the console number display unit and the comparison unit, and the reset results display unit. training, a switchboard of the consoles and a comparison unit, which is connected to the display unit of the number of the console and the memory unit of the learning stages connected to the switchboard of the consoles and the display unit of the survey results. FIG. 1 shows a block diagram of the proposed device; in fig. 2 - the belt diagram of the pulse distributor is given. The proposed device for teaching and controlling students' knowledge contains consoles 1 and 2 teachers and students, respectively. The teacher 1 control panel consists of input elements I 3 connected to the outputs of pupits 2 learners through switches 4 with outputs of the distributor impuces bis inputs of the elements OR 6 connected to the inputs of the coincidence block 7 and the comparison (learning stages) 8 connected with the input of the coincidence node 9 and the input of the coincidence input associated with the input of the memory block (learning stages) 1O connected to the input of the display 11 of the polling results display and to the output of the distributor of impulses 5 connected to the input of the coincident 9 usp associated with the input node 1 2 memories of the number of the workplace connected to the indicator 13 of the number of the workplace. Input elements AND 3, switches 4, pulse distributor 5, elements OR 6, match block 7, block compare 8, match node 9, memory block (learning steps) 1O, block 11, memory location number 12, indicator The 13 work station numbers are co structurally placed in the teacher 1 console, the nodes 9 and 12 and the indicator 13 form the console number display unit 14, and the elements 3, 4, 5 and 6 are the switch 15 of the panels. The proposed student learning control device operates as follows. The information about the step number from the pulses 2 is fed to the inputs of the elements 3. The beginning of the polling cycle of the students from the pulse distributor 5, designed for sequential polling of the consoles 2, and the input of the memory unit 10 receives the installation signal in one state, Without a switch 4 to the second input of the input element 3 of the first interrogated ultr 2, an authorization signal passes which the code of the stage through the ETH element 6 enters the comparison unit 8 and the input of the match unit 7. The content of the memory block 10 enters the input of the comparison unit 8 and is registered by block 11. Comparison block 8, executed according to the code comparison scheme, is less than or equal to the code, compares the code of the stage received from the console 2 with the code stored in memory block 10, and when comparing them, it gives a resolution signal to the coincidence unit 7 and match node 9. So times eshayuschemu signal code phase polled at any given time through the control panel 2 of matching unit 7 is input to the memory unit and is stored 1O MI, and the code is a sequence pulse number, pulses generated distributor 5 and is yuschegos simultaneously Ko.,. The house of the number of the polled remote control 2, through the match node 9, enters the input of the memory node 12 and is memorized by it, and its contents are recorded by the indicator 13 of the workplace number. Subsequently, the pulse distributor 5 performs a sequential interrogation of all the remaining consoles 2, but without issuing signals for the installation of the 1O unit to a single state. The operation of the console 1 is the same as described. When sequentially polling consoles 2 and comparing the codes of the stages of previous learners with the codes of the steps of the subsequent learners, the contents of memory block 1O and memory node 12 repeatedly change, as well as the numbers on indicators 11 and 13 until the minimum code of the stage is revealed. After polling the last incremental pulse distributor 5 is blocked (see Fig. 2). The change of numbers on the indicators stops. The blocking time is chosen sufficient for the teacher to visually see the displayed information. When the blocking time has elapsed, the polling cycle is repeated.

In order to detect the lagging learning teacher ppygo o disconnects the oonym from switches 4, the output distributes the impulses 5 from the hoop element

corresponding to the previously identified bullet 2.

Similarly, it is possible to detect successful students, for which it is necessary to perform a comparison unit 8 in the device according to a scheme comparing with the VII codes for more or equal, and at the beginning of each cycle to install the unit Yu in the zero state.

As a criterion for revealing

lagging and n | 1 students who are lagging behind can also take on the coherence of learning errors at intermediate control.

The application of the proposed device allows automating the detection of lagging and successful students, so as to reduce the size of the teacher’s teacher punctually.

Automating the search for the required information will objectively allow the W1} to lag the lagging students in order to free up additional time for the teacher to assist students and thereby increase

.effectiveness and accuracy of the learning process.
