switch 11, designed to distribute educational information, depending on its type of print, or through block 7 to block 2, and alphanumeric-c1n: a f-print node (ADC) 12, designed to present students with basic and additional questions as well as answers to clarifying questions.

Block 2 is executed in the form of a bitwise comparison with the registers at the input (the student’s response register and the reference response register) and two outputs: the contents of the registers were compared (the answer was correct), the contents of the registers were not compared (the answer was incorrect). The console, 3 consists of a panel of changeable data, a control panel and two encoders that convert the position code into a parallel one. The shift data panel, designed to form student responses, consists of 48 keys, each key using three registers is assigned one of three values. The control panel consists of ten keys with the help of which the ticket number and the question number are dialed, as well as the Enter, Evaluation, Additional question, Refining question, Reset buttons. The first encoder generates an address code by the numbers of the ticket or refinement device, and the second encoder forms the response code.

Block 4 contains a group of triggers with an open collector at the output and display elements.

Block 5 contains a counter 13 (the number of correct answers), a counter 14 (the number of questions), a group of elements AND 15, a group of elements OR 16 that are intended for determining zones Passed, Not delivered, a group of elements And 17, which is designed to generate signals. I didn’t pass, Continue the survey, after receiving the answer of the ticket ticket questions, the elements of AND 18, and the elements of OR 19 intended to pass the signal I did not pass to block 4.

Block 6 contains a register 20 for intermediate storage of the ticket number and question number, registers 21-24 for generating the address of the additional question} additional question counter 25, decoder 26, group of elements 27 and IL 28 for passing the address of additional questions question in block 1.

Block 7 contains a hold element 29, triggers 30-33, a counter 34, a decoder 35, elements OR 36-38, elements AND 39-41, groups of elements And 42 and 43, element And 44, elements 45 and 46 of the delay.

The device works the footing in a skinny way.

Before operation, the device is in the initial state: all the memory elements of the device are reset to the initial state by a test signal when the power is turned on (the setting signal generation unit when the power is turned on is not shown in the block diagram), and the triggers 30-33 the initial state, in this case, the element 40 and the groups of elements 42 and 43 from the trigger 32, the element 41 from the trigger 30 and the element 39 from the trigger 31 are given signals of a logical unit, and to the input of the block 4 s trigger 33 is served with I drove a logic zero.

In node 9, questions (basic and additional) are stored in a certain order, as well as reference answers and answers to clarifying questions. That is, the information is preliminarily recorded in the memory node in the following sequence. At the address consisting of the ticket number and the question, the first word is the reference response code, i.e. reference answer to this question, followed by the number and text of the question.

In the case of asking a clarifying question, the address corresponding to the clarifying question number is recorded in response to the question asked, and the place of the first word in the memory is filled with a code consisting of eight units for the employee to recognize the fact of the clarifying question. The additional question is concretizing or modified with respect to the main question. The address of the additional question is one more (in the lower order) addresses of the main issue on the topic.

The call to node 9 in the process of answering the questions to the students is carried out by an eight-bit code (addressing code), which is formed by register 8. Register 8 consists of two four-bit registers: senior

246126

The four bits form the ticket address, and the low fours form the address of the question, the youngest bit intended for recognizing the address of the additional question, and when entering the address of the main question in this bit, a logical zero is always written. Between registers 8 and 10 and node 9 are mating circuits that are not shown in the block diagram.

The output busbars of blocks 3 and 6 at the input of register 8 are combined with command receivers having a high impedance state when disconnected from the bus. In the specific case, open-collector AND-NOT 2 elements are used with pairwise connected outputs.

The node 9 also includes a synchronizer that absorbs the synchronization pulses necessary for the process of writing and reading information.

Reading information from node 9 occurs sequentially, i.e. Register 10 receives a serial code and, every eight clock cycles, issues a parallel eight-bit code to the input of switch 11. By the time the first word arrives (reference response code), the inputs of switch 15

the reference register through the elementalized group of the response of the block 2, comrade I 42.

 The codes are sent by clock pulses.

After reading the first word from the node 9 through the register 10, the inputs of the switch 11 switch to the direction of the node 12, and the subsequent information is printed.

Structurally, switch 11 consists of two key circuits (eight inputs and eight outputs each), combined at the input, and a control trigger. Switching circuit (flip-flop trigger) produces- with a pulse following the first clock pulse, which reads the first word from 0 register 10.

The code, consisting of eight units, serves to identify the clarifying question and is used in controlling the operation of block 7, for which the output of the switch 11 (parallel to the bus connecting to block 7) connects to the eight input matching circuit, the output signal of which knocks over

fixer fixing task. interrogation and is entered into the remote control 3 to set up a trigger command 33.

The trigger of fixing the fact of specifying the s of the querying question is controlled by the operation of the coincidence circuit, and the second input of the coordinator receives a signal from the switch 11 (a clock pulse controlling its operation). This signal uses 10 seconds to control the trigger 32. In the block diagram of the training device, the elements that form the control commands (signals) for the triggers 32 and 33 are not indicated, because the circuit solution and the functional value of the elements of the formation of these commands are determined by the specific type of external memory using the node, the circuit design of block 1, the type of the element base 20 and do not affect the principle of operation of the device as a whole.

The functionality of the elements 31, 33 and 34 is as follows.

To turn off (or turn on) 25 of block 7, a trigger 31 is used, which has two control inputs (except for the initial reset). When a control signal arrives, for example from block 5 - command 30 Additional question, trigger 31 overturns, its corresponding outputs block the control inputs of elements 30 and 39, which also the Answer command is incorrect (in case of an incorrect response), does not affect to the state of the elements of the block 7. If necessary, the block 7 can be turned off by applying to the control input of the trigger 31 a logic zero signal from the switch (switch) intended for this purpose.

Trigger 33 serves to control the operation of the board Answer the main question. His job is as follows. When a command is received, the Answer is incorrect, elements 29 and 30 flip over trigger 32 and its inverse; the 1st output gives permission for the control signal to pass through element 50 to trigger input 33. The signal controlling the state of trigger 33 comes from the block 3 through element 46, when entering the number of the clarifying question in block 1. In this case, the trigger 33 reverses-55 is given and the signal of the logical unit from its output turns on the digital display.

Counter 34 counts the number of replies (by the number of incorrect answers) and slutkit to correct the results of responses. Its contents increase by one with each incorrect answer, even if the wrong answer was given several times to the same question.

In the course of operation, with the student learning device, by pressing the keys of the console 3, it dials the ticket number that goes to the most significant bit, register 8 and, through the I element of group 43, into the most significant bit of the register 20.

The ticket number is the starting address at which from the node 9 is read, the ticket issue and through register 10 and switch 11 are output per pb; read node 12 and thus are presented with the note. Students can answer ticket questions in any order. To do this, it generates the question number to which the answer will be sent using the keys of the remote control 3. The question number code from the remote control 3 goes to the bits 8 and 20 that follow the ticket number. Thus, in register 8, the address is formed. ) To the th node, the reference response from the node 9 is read in via the register, the register 10, the switch 11 and the AND element of group 42 into the register of the reference response of the block-2.

The student using the keys of the patch data panel of the console 3 generates an answer to the question and, by a signal, enters it into the response register of the student unit 2. In unit 2, the student’s response is compared with the reference answer and, depending on the correctness of the response, the output of the unit 2 the Answer signal is correct, or the Answer signal is incorrect.

If the answer is correct, then the Answer is correct from block 2 goes to counter 13 (the number of correct answers from block 5, through elements 38, 40, 37 to counter 14) (the number of questions), as well as to the input of block 4, where a signal is displayed The answer is correct. After that, most of the questions go to veto on the next question of the ticket.

If the student’s answer is incorrect, then the Answer signal is incorrect from block 2 through element 41 enters block 6 and is authoritative for rewriting

7.1246

addresses formed by ticket number and main question number, from register 20 to register 21. In the additional low-order bit of register 21, a unit is written that allows the address of the next Number to be written to the incorrectly answered question from register 20 to register 22 .

 At the same time, the Response signal is incorrect. From block 2 enters element 29.10. The delay time is selected sufficient to overwrite the contents of register 20 into register 21.

From the output of element 29, the response signal is unreliable; through element 39 it is fed to the input of trigger 30.

At the same time, at the output of the trigger 30 a signal of a logical unit is applied, supplied to the trigger 32, to the element AND 44 and to the input of the counter 34, 20 increasing its content by one. The trigger 32 overturns, a logical unit signal is also generated at its output, which is fed to the input of block 4, where a 25 signal is displayed Ask a clarifying question, and the logic zero signals from the outputs of flip-flops 30 and 32 block elements 40 and 41 and groups 42 and 43, blocking the input of the counter 14, the input of the register of the codes of the reference responses of block 2 and the inputs of registers 21-24, thereby prohibiting the rewriting of the subsequent information from register 20 to registers 21-24.

When displaying the display of the 4th signal block, ask the clarifying question that the student selects the clarifying question related to this topic from the proposed list, using the keys on the replacement data panel of the remote control 3, forms the clarifying question number and presses the Enter button of the remote control 3..

When you press the Enter button on the console, the 3-question number is written into register 8. The number of the clarifying question is the address at which the answer to the clarifying question is read from node 9 and through register 10, 50 switch 11 is printed to node 12 and Present is learning. At the same time, additional information is not transmitted to blocks 2, 5 and 6, since their inputs are blocked by a logic zero signal 55 supplied from flip-flop 32 to the inputs of element 40 and groups 42 and 43.

1268.

With the introduction of B, the block 1 of the number of the querying question from the console 3 to the element 46 is given a control signal. The delay time is chosen sufficient for printing the answer to the clarifying question. From the output of element 4b, the control signal from the console 3 is fed through element 44 to the input of the trigger 33. At the same time, a logical unit signal is generated at its input to the input of unit 4. A signal is displayed on the light panel of unit 4. Answer the main question of the ticket What students, having received the answer to the clarifying question, can repeatedly answer the main question of the ticket.

The opportunity to ask a clarifying question is presented by the student if the answer to any question of the ticket is incorrect.

In the second attempt to answer the main question, the signal of the logical unit from the switch 11 overturns the trigger 32. This unlocks the elements 40 and groups 42 and 43 and the second answer is entered into the response register of the learning unit 2. In block 2 again the comparison of the student's answer occurs reference response. Depending on the correctness of the response to the output of the comparison circuit of block 2, either the Answer signal is correct or the Answer signal is incorrect, which are sent through elements 38, 40 and 37 to counter 14 (the number of questions). If the answer is correct, then the signal from block 2 arrives at counter 13 (the number of correct answers). Regardless of the results of the response, the signal is correct or the Answer is incorrect from block 2 also appears on the input of block 4, where it is remembered and displayed -.

After that, the student proceeds to answer the next question of the ticket.

It should be noted that for each main question address code (number

ticket and question) is dialed on the remote 3 only once, i.e. when replying again (at the second attempt to answer the main question), the ticket number and question are not dialed.

In console 3, in the ticket number and question dialing node, there is a scheme for setting zero buffer triggers to form the number code.

This scheme generates a single pulse of the corresponding polarity, when you press any of the dial buttons

addresses which through the coincidence circuit located in the console 3 enters block 7 to reset the triggers 30 and 33 to the initial state. When a command appears, specify the qualifying question, the input of the coincidence circuit is blocked by the command of this command, prohibiting the passage of the setting pulse O in block 7 (in the process of dialing the address of the clarifying question), since a repeated answer to the main question does not require dialing the address number of the next main question, triggers 30 and 33 retain their state even when dialing the first address code of the next question these triggers are reset and the element 41 is unlocked and the inputs of registers 21-2 are unlocked

In the process of answering the ticket questions, the number of correct answers is accumulated in the counter 13, and the number of questions in the counter 14. The result of the mutual correlation of the number of correct answers and the number of questions, carried out by elements 15 and 16, corresponds to one of the zones I passed, I did not pass, Continue the survey. In forming the result of the mutual correlation of questions and answers, it takes into account the number of clarifying questions asked by students in the process of answering. For this purpose, a decoder 35 and elements IfUlIi 36 and 37 serve. If the number of clarifying questions asked by the ticket ticket, exceeds a certain value (determined by switching the corresponding outputs of the decoder 35) from the corresponding outputs of the decoder 35 through elements 36 and 37 on the input of the counter 14 receives a signal that increases its content by a specified number of units.

In block 6, the addresses of questions that the student answered incorrectly are written in succession. The unit in the lower order of registers 21–24 increases the address of the question by one, and thus the addresses of additional questions are formed in them only on those topics that are answered with student errors.

In block 4, information is displayed on the correctness of the answers to the ticket question asked.

After answering all questions of the student ticket on the remote 3 forms

Signal Evaluation, which allows passing of the signals Pass, Fail, and Continue the survey, i.e., the result of the mutual correlation of the number of correct answers and the number of questions, formed taking into account the number of clarifying questions asked by students. If the result of the vaamoam correlation corresponds to the zone passed, then the signal from the output of the corresponding element 16 through element 1 enters the input of block 4, where it is stored and displayed. If the cross-correlation result corresponds to the zone Not passed, then the signal from the output of the corresponding element 16 through element 17 and element 19 is fed to the input of block 4, where it is stored and displayed.

If the result of mutual correlation corresponds to the zone Continue polling, then the signal c, the output of the corresponding element 16 goes through element 1 to the resolving 1st input of the counter 25 and to the input of the trigger 31. At the same output of the trigger 31, a logical zero signal is formed, locking the element 39, and at the other output, a logic unit signal that triggers triggers 30 and 32 to the initial state, in which the input of counter 34 and element 44 are locked, and elements 40, and 41 and groups 42 and 43 are unlocked. I

At the same time, the board lights up. The additional question in block 4. The student on the remote control 3 by pressing the button generates a signal. An additional question that arrives at the counting input of the counter 25, sets it to the unit state.

This state of the counter 25 is analyzed by the decoder 26, at the output of which a signal appears enabling the reading of the address of the additional question from the register 21.

Thus, through the corresponding elements 27, elements 28, the register of the first additional question is entered into the register. This is a question on the first of the topics for which the student has rejected: wrong. At the address of the additional question, from node 9, the first additional question is read out, which through register 10 and switch 1 enters node 12 and presents a learning pattern.

n

The reference answer to this question is read out from node 9 through the register switch 11 and group 42 enters block 2 (in the reference answer register). Uchanschis forms the answer to an additional question on the remote 3 and enters it into block 2 by pressing the Enter button. The signal from the output of the comparison circuit of block 2 enters the elements 38, 40 and 37 into the counter 14, increasing its content by one. If the answer to the additional question is correct, then the signal from the comparison output of block 2 enters the counter 13. The result of the mutual correlation may again correspond to one of the three zones Passed, Not passed, Continue the survey. If the result of mutual correlation again corresponds to the zone. Continue polling, then a signal about this from block 5 is again sent to the enable input of counter 25 and in block 4 the board lights up. Additional question, etc.

The student answers the additional question until the result of the mutual correlation in block 5 corresponds to the zone passed, or not passed, or until the number of attempts exceeds the specified number, as indicated by the signal from the output of counter 14, passing through element 18, element 19 at the input of unit 4, and indicated on it as Not passed.

In the process of answering additional questions, the possibility of answering clarifying questions is excluded, since block 7 is blocked by a signal from element 15 that is applied to trigger 31, which is then locked by element 39.

The trigger 31 and the counter 34 (as well as the trigger 33 at the end of the response cycle) return to their initial state with the signal generated by the Reset button of the remote control 3, which is locked during the response, and unlocked only after fixing and indicating the evaluation in block 4. Krom In addition, the elements 31, 33 and 34 of block 7 are reset to the initial state by a signal generated when the power of the device is turned on.

The proposed device, possessing the same versatility as the known ones (the entire educational information is stored in memory devices), allows to expand the didactic
