According to the main author. Ev, No. 9820625, there is a known device for teaching and controlling students' knowledge, containing sequentially included learning consoles, a switching unit and a first comparison unit S as well as recording units m of indication, sequentially connecting a phase counter teaching a pulse distributor and a memory unit 5 whose output is connected to the input display unit, and the I-fflHs element connected in series, the counter of the number of trainees and the second comparison unit, the second input of which is connected to the output of the registration unit and the output to the second input of pulse generator and the first input of the element OR whose second input is connected to the second output of the switchboard of the consoles connected to the third input of the pulse distributor and the input of the counter of the learning stages of the second which is connected to the second input of the first comparison unit, quickly,: which is connected to a quarter of the input of the pulse distributor first and the second outputs of which are connected, respectively, with the input of the regi-station unit and the second input of the counter kOG},

This device allows the AETO to provide operational information to the teacher about the stage of the program that studies the most number of students; However, in order to effectively manage the learning process in the study group, information is needed about those who are lagging behind in order to provide them with timely assistance. Such information device does not provide the teacher.

The aim of the invention is to expand the didactic capabilities of the device by automatically identifying lagging students with the number of the stage in which it is located.

The goal is achieved by the fact that the device has sequentially inserted an additional delay element, the trigger and the memory block whose output is connected to the second input of the indoor unit; and the second input with the second output of the central memory block S and the chains of the series-connected element I, memory element and indicator, the first inputs of the elements And chains connected to the third output of the switchboard of the consoles, the second inputs - with the output of the additional triggers . and third inputs from one of the outputs of the pulse distributor connected to the input of the additional delay element

In the drawing is a pre-presentation of the proposed device.

The scheme includes a remote student and remote 2 teachers,. Pu.pt 2 consists of a switch of 3 consoles; E-ioro is connected to the outputs of the console 1 and to the inputs of the unit 4 of the comparison, element IPI 5, trigger 6, counter 7, the number of stages (sections). The output of block 4 through the element AND 8 is connected to the input of the counter 9, the number of trained i-C: .Xs and through the element 10 - to the input of the counter) 1 the number of students you moves the counter 9 and 11 connected to the inputs of the comparison block 12 whose output is connected to the input of the element OR 5 and the installation bus to the zero state of the trigger 6. The output of the element OR 5 is connected to the bus of the installation set to not, the left state of the counter is 1 1, the zero output of the trigger 6 is connected to the element 8 and single output with AND -0. Counter 7 is connected to the block: and through the node 3 of the elements And to the block; 4 memories. Connected to the indicator 1b (stages). The output of the element And 8 is connected with a bank 4 and through the delay element 16 with the node 13 "Output 9 of the counter 9 is connected to the indicator 17. The device also contains delayed element 8 connected in series, trigger 19, memory block 20 and indicator 21 The input element 18 is connected to the output element AND 8. The output element 18 is connected to a single input trigger 19 In addition, the device contains: m chains of registration of lagging learning classes whose number is equal to the number of learning consoles;:. Each lagging-up registering chain contains an AND 22 element, a memory element 23 and an “24 (individual OTC Tamaie terminal) element 23, the And 22 element inputs are connected to the switch output 3 guls. With the output of the element K 8 and with the nouveau output of the trigger 19. The installation tires in the zero position of the counter 9, the counter 7 and the trigger 19, as well as the element 23 are connected to the output of the element 25, one input of which is connected to the output of the generator 26s and the other through the element 27 delays with switch output of 3 consoles. The switch 3 of the consoles consists of the input elements AND 28, the distributor 29 of pulses and the element OR 30. The distributor 29 may consist of a pulse generator, a pulse counter and a decoder (not shown). Due to the fact that a multi-digit code is received from console 1, elements 28 and 30 consist of several identical circuits. Blocks 4 and 12 compare two incoming codes for equality. The trigger 6, the elements of And 8 and 10, b and the node 14 represent the distributor 3 pulses, the counter 9 and the indicator 17 - the block 32 registration, and the indicators 15 and 21 - the block 33 of the display. The proposed device works as follows. Information about the number of the stage (the number of studied sections) from the remote control 1 goes to the inputs of the elements.28. At the second input of the element 28 of the first surveyed console 1, the distributor 29 receives an enabling signal, through which the stage code through the elements 28 and 30 enters the comparison unit 4. From the output of counter 7, the code of the stage (the code of the first stage is returned to the initial state in counter 7) is supplied in binary form to block 4. Thus, block 4 receives two codes of the code of the interesting stage and the code of the stage of the console that is being polled at the moment 1. These codes are compared and, in the event of a match, block 4 generates a comparison signal which, through element 8 (in the initial state, the trigger & is in the zero state) is fed into counter 9 and adds one to its previous state. The distributor 29, through a polling period, sends a signal to the next element, And 28, and block 4 at this moment compares the code of the next control stage 1, etc. So, during the polling cycle, the number of trainees 9 accumulates the number of trainees learning at that moment on the counter 7 stage (section) of the training program. The code for the number of trainees comes from counter 9 to block 17 and highlights to the teacher the number of trainees who are learning at this moment the stage (section) of the training program installed on the counter. From the output of the element And 8 is fed to the block 14 and zeroed it, at the same time this signal through the element 16 is fed to the node 13, and the code of the stage of the training program, recorded in the counter 7, is recorded in the block 14. The stage comes from the block 14 in block 33 n eb sbschivaet teacher number espsa (section). After completion of the polling cycle, the distributor 29 outputs a signal to the element 1, 5, trigger 6, and counter 7. In this case, the trigger 6 is set to one state, and one is added to counter 7. Counter 11 is set to zero. After this, the polling cycle is automatically repeated. But in this case, the comparison signal, produced by block 4, goes through AND 10 to counter 11 (since trigger 6 is set to one state) and adds one to its previous state. If in the course of a survey on a given cycle the number of units written in counter 1 does not become equal to the number of units recorded in counter 9, at the end of the cycle of inquiry the p; distributor. 29 generates a signal, n on ELSME NT 5, trigger b, counter 7; In this case, trigger ger 6 remains in a single state. One more unit is added to counter 7. Counter 11 is zeroed. In this case, block 17 shows the number of trainees during the first survey, and block 15 indicates the number of the first stage. The polling cycle of the switchboard is repeated at the new stage number. If during the polling on this cycle, the number of units recorded in counter 11 becomes equal to the number of units recorded in counter 9, from the block. a signal is sent to the element OR 5 and to the trigger 6. At the same time, the counter 11 is zeroed out, and the trigger 6 is set to the unit state and at the next interrogation of the console 1 the comparison signal, via the block 4, is fed through the element 8 to the counter 9. Thanks to the signal coming from the code of element 8 to block 14, the node 13 records the number of this stage. After verifying the interrogation cycle, the limiter 29 again issues a signal to element 5, trigger 6, and counter 7 In the future, the device operates as described. In this case, the counter 7 provides continuous sequential enumeration of the codes of all stages. At the first match of the code of the stage of interest and the code of the stage that the console is currently polling, the signal from block 4 through elements 8 and 18 of the flip-flop 19 is set to one. At the same time, due to the fact that the delay time of the element 18 is not less than the polling time of the switch 3 of all the consoles 1, the signal from the zero output of the flip-flop 19 records the contents of the block 14 into the block 20, the contents of which are displayed by the display block 33 (the teacher is presented with the information about the lowest stage on which are lagging learners). In addition, due to the presence of a signal from the zero output of the trigger 19, each time a signal appears at the output of element 8, element 22 is connected, connected via corresponding element 28 to interrogated console 1. Signal from element 22 turns on corresponding memory element 23, and the indicator 0 3 24 is displayed the number of the student lagging student’s desk (the teacher is automatically provided with information about the student who is lagging behind). Herewith, due to /, that a new polling cycle can begin after a time not less than the delay time of element 19, when a signal is output from element 8 during subsequent polling cycles, state 23 of elements 23 cannot occur, since the inputs of elements 22 connected to zero output of trigger 19, no signal (trigger 19 by signal from element 18 is set to one state j, Dp to ensure correct operation of the device (to ensure timeliness of information presentation) counters and memory elements periodically zero signals from generator 26 (for example, with a period of 30 seconds) through element 25. The use of the proposed device allows automatic presentation of information to the teacher about lagging students with an indication of the number of the stage at which they are located, which makes it possible to timely assist the lagging students and ultimately improve the effectiveness of the learning process.
