The training device contains a group of individual training devices 1, memory block 2, priority block 3.

The priority block 3 contains a clock generator 4. multiplexer 5, inverter 6, element And 7, counter 8, decoder 9, group of elements AND-NOT 10.

Each individual training device 1 includes a student console 11, a block 12 for comparing answers, an indication block 13, a block 14 for calculating the mutual correlation of questions and answers, a block 15 for selecting an additional question, a block 16 for making decisions, a block 17 for presenting educational information, The first of the first register 18 (input), the second register 19 (output), the switch 20, the registration unit 21, the third request register 22, the decoder 23.

The device works as follows.

Before starting, all individual training devices are in the initial state: all elements of the training devices 1 and unit 3 are reset to the initial state when the power is turned on (the control unit that generates the setting signal when the power is turned on is not shown), while at the outputs of the unit 3, the signal of a logical unit that, applying the control inputs of registers 18 and 19 of block 17 of all training devices, 1, creates a mode of prohibiting the release of information (registers 18 and 19 are 8-bit registers with three states of you: single buses - 1, O or high impedance barring condition).

In block 2, questions (basic and additional), as well as reference answers and answers to clarifying questions on M topics, are stored in a certain order. At the address consisting of the topic number and the question number, the first word is the reference response code, incl. reference answer to this question, followed by the number and text of the question.

The memory 2 is addressed in the student’s response process by an eight-bit addressing code, which is generated by register 18. Moreover, the upper four bits of the formed register 18 of the single-byte addressing code contain the address of the topic being studied, the least significant is the address of the question; recognizing the address of an additional question, and when entering the address of the main question in this section, a logical zero is always written.

51

The access signal from register 18 passes to block 2 only after the prohibition signal is removed from the control inputs of registers 18 and 19, coming from block 3.

A mating device (not shown) is provided at the inlet and outlet of the block 2.

The output busbars of the blocks 11 and 15 at the input of the registers 18 and 22 are combined with command receivers having a high impedance state when disconnecting from the bus. In the specific case, the multimode buffer register K589 IR12 is used as a command receiver.

When the power is turned on, the generator 4 begins to generate clock pulses arriving at the 2nd input of the element 7. Counter 8 is in the initial state.

At the same time, a signal of a logical unit is generated at the first output of the decoder 9, which is applied to the second input of the first element NAND 10 and unlocks it. From the output of the counter 8 to the address input of the multiplexer 5, a code word is supplied, under the action of which the multiplexer 5 switches the output to the output from its decoder 23 of the block 17 of the first training device 1.

If a student working on the first training device 1 has not yet typed 11 the topic number and question number on the keys of his console, then the output of the decoder 23 of the first training device 1 is a logical zero signal. This signal through multiplexer 5 is fed to the first input of the first element AND-NOT 10, causing a signal of a logical unit at its output.

Signal unity signal. From the first output of block 3, it is applied to the control inputs of registers 18 and 19, the mode of prohibiting the issuance of information is preserved.

At the same time, the logical zero signal from the output of the multiplexer 5 is fed to the inverter 6, the signal of the logical unit from the output of which unlocks the And 7 element. At the same time, through the And 7 element, the counter 8 receives the clock pulses from the generator 4.

When at the control output of counting 8, under the action of clock pulses, the next allowed code word is generated, which is fed to the control input of multiplexer 5, 246

The second switches the output signal from its second input, etc.

Suppose that by the time of switching the i-ro input of the multiplexer 5 students, working on the i-th individual learning device 1 way

Pressing the keys of his console 11, already dialed the number of the topic and the number of the question that goes to register 18 through block 16 to block 15 and to register 22 of the query i-ro learning device 1. A code combination is formed at the output of the register 22 decoder 23. At the same time, the signal of a logical unit appears at the second output of the i-ro training device 1. This signal is fed through multiplexer 5 and inverter 6 to the AND blocker element. As a result, the counter 8 is disconnected from the generator 4, thereby fixing the ie the state of the multiplexer 5. Thus, the multiplexer 5 is in the i-th state until the second output of the i-learning; units.

At the same time, the signal of the logical unit from the output of multiplexer 5 is fed to an open control signal from the i-ro output of the decoder 9 i-th element AND-NOT 10. At the same time, the i-oM output of block 3 generates a logical zero signal, which through the second input i- The ro tutor device 1 arrives at the control inputs of registers 18 and 19, lifting the prohibition on issuing information, i.e. connecting the output buses of these registers respectively to the input of block 2 and to the input of switch i-ro 20 of training device 1. The incoming from register 18 of i-ro training device 1 to block 2, the topic number and the question number are the address from unit 2 sequentially reads the text of the question, which through the register 19 and the switch 20 is fed to the registration unit 21 and displayed on the seal to verify that the students have correctly entered the required address and the text of the standard answer to the question received through the register 19, the switch 20 and the bl to 16 in the block 12 i-ro training device 1. Thereafter registra.22 reset is performed while the output of decoder 23 i-ro training device 1 is formed by a logic zero signal. This

the signal goes through its second output to the iH input of the multiplexer 5. In this case, unit 3 generates a prohibition signal applied to the control inputs of registers 18 and 22 of the i-ro device 1, multiplexer 5 switches the output signal from (i4-1) -ro login, i.e. priority block 3 checks for the presence of a request signal (i + + 1) -th, (i + 2) -th, and so on. training devices 1, alternately switching them in the presence of a request signal with block 2.

A student who works on the i-th training device 1 using the keys of the panel of changeable data of the console

11 forms the answer and the input signal enters it into block 12. In the block

12, the comparison of the response of the participant with the reference response occurs and, depending on the correctness of the response, at the output of the block 1 2, either the Answer signal is valid or the Answer signal is incorrect.

If the student’s answer is correct, the signal is correct Answer from block 12 goes to the counter of the number of correct answers of block 14 and through block 16 to the first input of block 15, as well as to the first input of block 13 of the display i-ro of the training device 1, where the signal is displayed The answer is correct, after which the student begins to answer the next question. If the student’s answer is incorrect, the Answer signal is incorrect from block 12 through block 16 goes to block 15 for selecting an additional question, where the address formed according to the topic number and the number of the main question is overwritten by adding a unit to its younger bit, as well as to the block 16, where the information signal is generated, fed to the third input of block 13, where the signal is displayed. Ask clarifying questions and a control signal blocking the inputs of blocks 12, 14, 15 of the i-ro training device 1.

When a signal is displayed on the display of block 13, ask a clarifying question the student selects the clarifying question related to the topic being studied from the list, using the keys on the change data panel of the remote control 11, forms the clarifying question number and presses the Remote control button 11.

When you press the Enter 11 button on the console, the number of the clarifying question is recorded in registers 18 and 22, forming the request signal at the second output of the i-ro training device 1 using the decoder 23. When the request signal arrives at block 3, the ban is removed from the registers 18 and 19 i- ro training device 1 and the number of the clarifying question, which is the address, goes to memory block 2, from where the answer to it, through register 19, switch 20 is printed on block 21 of registration i-ro training device 1 and is presented to the student. At the same time, the additional information in blocks 12, 14 and 15 of the i-ro training device 1 is not transmitted, since their inputs are blocked by the control signal from block 16.

When the UTO number of the clarifying question is entered into block 17, the control signal from the console 11 through block 16, where it is delayed by the printout of the answer to the refined question, is sent to the third input of block 13. At the same time, block 13, the signal is displayed Answer the main question.

The opportunity to ask a clarifying question is presented to the student if the answer to the question on the topic being studied is incorrect.

In the second attempt to answer the main question, the signal of the logical unit from switch 20 is fed to the second input of block 16, forming at its outputs a signal unlocking the inputs of blocks 12, 14 and 15 of the i-ro training device 1. At the same time, block 12 is entered a second answer the student from the console 11. In block 12 again, the student's response is compared with the reference answer. Depending on the correct answer, either a signal is generated at its output, the Answer is correct, or the signal is Answer is incorrect, which are sent through block 16 to the counter of the number of questions of block 14 and, if the student’s answer is correct, to the counter of the number of correct answers of block 14. Regardless of the response results, the signal The answer is correct or the answer is incorrect from block 12 is also fed to the first input of block 13 of the i-ro training device 1, where it is stored and displayed.

Il icjip chto p utrasigtyG starts to consider the next nimpoca topic.

In the course of the student's answer to questions on a specific topic, the number of correct answers accumulates in the counter of the number of correct answers of block 14, and the number of questions in the counter of the number of questions of block 14. The result of the mutual correlation of the number of correct answers and the number of questions corresponds to one of the zones I passed, I did not pass, Continue the survey.

In block 15, the addresses of questions to which the student answered correctly are successively written; at these addresses, by adding one to the lower order, addresses of additional questions are formed in the same sections.

After answering all the questions on the topic, the student on the console 11 of the i-ro training device 1 generates an Evaluation signal, which interrogates the result of the mutual correlation of the number of correct answers and the number of questions generated taking into account the number of clarifying questions asked by the student block 14.

If the result of mutual correlation corresponds to the zone Passed or the zone Not passed, then the corresponding signal from block 14 is fed to the second input of block 13, where it is stored and displayed.

If the result of mutual correlation corresponds to the zone Continue polling, the signal from block 14 goes to block 15, to block 13 and to block 16. At the same time, the scoreboard lights up. Additional question in block 13. The student on the remote control 11 by pressing the button. The additional question generates a signal which, entering through block 16 to block 15, permits the reading of the address of an additional question.

In this case, the registers 18 and 22 of the i-ro training device 1 are entered in the address of the first additional question. At the output of the decoder 23 i-ro training device 1, a request signal is generated, which is fed to block 3 and removes the prohibition signal from the control inputs of registers 18 and 19 of the i-ro training device 1. At the address of the additional question from block 2, the first additional question which

through register 9, switch 20 enters registration block 21 and presents it to the student, as well as a reference response to it, which through register 19, switch 20 and block 16 enters block 12.

The student forms the answer to the additional question on the remote control 11 and enters it into block 12 by pressing the Enter button, where this answer is compared with the reference answer. If the answer to the additional question is correct, then the signal from the output of block 12 enters the counter of the number of correct answers of block 14. The result of the mutual correlation may again correspond to the 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 14 is again sent to the enabling input of block 16 and again in block 13 the board lights up. Continue polling, etc.

In the process of answering additional questions, the possibility of answering clarifying questions is excluded, since block 16 is blocked by a signal of block 14 and is unlocked only after fixing and indicating an estimate from block 13. In addition, block 16 is reset, as well as all other blocks the training device, when turning on its power.

The student answers additional questions until the result of the mutual correlation in block 14 corresponds to the zone passed, did not pass, or until the number of attempts exceeds the specified number, which also leads to the formation of the signal not passed at the output of block 14.

After finishing the answer and reading its result from the board of block 13, the student can receive questions from the teacher on the next topic and begin to master it.
