Description

i

The proposed device relates to the technical means used in the educational process for the systematic monitoring and training of students.

Devices are known that are used in the learning process in the control of knowledge and learning of students.

Devices for controlling students 'knowledge with selective input of an answer provide control of students' knowledge on several tickets with a no-charge amount for answers to all tickets.

However, these devices do not allow training in branched programs and are not designed to enter a response in the form of a multi-digit number.

Group learning devices consisting of a central unit, student consoles, and the Tablo-Class, Overhead Projector, Tape Recorder consoles provide B operation for the Control mode, as well as the implementation of training programs with wide branching. At the same time, the input of answers was carried out from the consoles of the students with a telephone dialer and expressed in the form of three-digit numbers in the decimal system, the most convenient and familiar for any contingent of students.

The encoded information is read from the film by photodiodes in a MO (2

Ment pass and light through the holes in the film. Each bit of the underestimated number makes its place on the plop, the reading of one digit of the number is done in the moving state, but only after a special tape drive mechanism is installed between the illuminator and the photodiode system.

These devices have the following residues:

- the possibility of simultaneous servicing by the central unit of work from several remote controls was excluded, which causes an overhead on waiting for the queue when entering answers;

- it takes a lot of time to enter answers spent on reversing the search for a section of films with correct answer codes for each ticket number and stopping it in the correct position to read each three characters contained in the answer;

- the complexity of the design of the tape mechanism of the mechanism due to the need to provide the film with reverse movement in the process of searching for a pair of sections with a code of answers of the called ticket number;

- the mechanical strength of the film decreases after the holes corresponding to the correct answer codes are applied to it, and the reverse movement contributes to its rapid

wear and tear in the event of minor defects;

- the number of possible vonros in the ticket is limited (no more than four), which reduces the possibilities of using the device in the educational process;

- a strict sequence of input answers, starting with the first {and not of LOB of four), brings additional inconvenience for students;

- the form of answers, expressed in only three digits, limits the choice of tasks and questions suitable for implementation using this device.

The purpose of the invention is the expansion of didactic possibilities, increasing the reliability and speed of the device.

The goal is achieved by introducing into the device blocks of continuous reading of ticket numbers and continuous reading of ver1 first responses, the inputs of which are connected to the information carrier block, and the outputs are connected respectively to the inputs of the comparison block of the ticket number and a second comparison of the answer interconnected, the second input the ticket number comparison unit is connected to one of the outputs of the ticket number memory block, the inputs of which are connected to the predavator information display and the student workstations, the second The ticket number memory block is connected to the teacher information board, and the third one is connected to the permission block for entering the question number, the output of which is connected to the memory block of the question number, the first output of which is connected to the operating mode switching unit and the storage medium block, and the second output is connected to the response input resolution block, the output of which is connected to the bit memory of the response, its first output is connected to the bit comparison response block, and the second is connected to the response bits switching unit, and its output node It is connected to the block of comparison comparing the answer, the output of which is connected to the information board via the mismatch block.

The block diagram of the device is shown in the drawing.

The student knowledge control device consists of student work stations 1, each of which contains keys used to provide response information in the form of numbers, indexes and symbols, keys for service commands, a diode decoder, a binary counter, an OR-and a transistor switch controlling the arrival of pulses from a generator common to all workplaces; block 2 of the ticket number memory consisting of binary counters and transistor switches; block 3 we have the question number, represented by us, it is a binary counter; block 4 of the bit memory of the response containing the binary

counter; block 5 for entering the question number; block 6 permission to enter a response; block 7 ticket number comparison; block 8 of a standard comparison of a response, consisting of comparison elements and a diode array; block 9 switch bits of the response, which contains a binary counter, the elements of the comparison and logic "OR NOT; mismatch fixing unit 10; block 11 of the formation of the final team, having in its composition the triggers and logic circuits; a continuous ticket number reading unit 12 consisting of photo sensors and driver amplifiers; block 13 for continuous reading of correct answers; block 14 of information carrier, which is a hollow thin-walled drum of transparent material, on the side surface of which removable paper tapes with information on the ticket number and answers to tickets are coded; a mode switching unit 15; the information board of the students 16 and the information board of the teacher 17.

Depending on the need, the device can operate in the following modes.

“Self-control - allows for self-control of knowledge, as well as in solving problems. Answers to questions are entered in any order. As you enter each correct answer on the information board 16, a signal light turns on.

"Training - allows you to control knowledge and solve problems that require the definition of a logical sequence of actions and a programmed sequence for entering answers.

"Control -. gives you the opportunity to control the knowledge of students.

In this mode, the answers to the questions posed in the ticket are entered in any sequence, but the information about which answers turned out to be correct and how many correct answers will be learned only after completing work on all questions of the ticket.

Zan in the workplace, the student must, using his console, dial the number of his control ticket, and then begin to work on the questions (tasks) placed in the control ticket. The control ticket number is assigned to this operating console, which excludes the possibility of entering the correct answers in it relating to a different control ticket number. The ticket number is entered into the machine only once at the start of work and at subsequent entries of the answer n; ticket questions are not repeated. The memory of the ticket number attached to each working console at the end of work can only be reset by the teacher.

The device works as follows.

The information collected by the student about the ticket number from the working console 1 enters into the memory number 2 of the ticket number, and then into the number 7 comparing number bi. eta. At the same time in

unit 7 receives continuously signals about the various ticket numbers provided for this chain of control: information carrier unit 14, unit 12 for reading ticket numbers.

The moment of coincidence of the entered ticket number with a similar one from among equal and continuously posting ones from block 14 is fixed, and block 8 of the random comparison of the response receives signals permitting the comparison of the random response by the question number entered by the student. The signals provided provide a one-by-one comparison of the answer to a question only by the number of the ticket communicated from the work desk 1 at the beginning of work.

From block 2 of the ticket number memory, block 5 of the permission to enter the question number is given a signal, which allows the signals about the question number given by the students from their work desk to enter the question number memory 3.

In block 3, at the end of the process of memorizing the question number, three sigpals are formed. One signal is fed to block 14 and provides all the information located on the tape corresponding to the question number.

The second signal through the mode switching unit 15 is fed to the information board 16 and prepares to turn on a signal lamp corresponding to the question number and the number of the operating panel from which the signal about the question number was entered. The signal light can light up only by the signal from the final command generation unit 11, which arises if the entered training answer is correct.

The third signal arrives at block 6 of the answer entry permission. The latter provides a skip signal about the bit content of the response entered by the student from the work station 1 to the address of block 4 of the response bit memory, in which the contents of the answer are remembered a bit and the memory is reset (for possible storage of the next bit) after comparison in the block 8 is a comparison of the response of each successive bit.

In block 8, control of the bitwise comparison of the entered response with the random content of the correct response received via the correct response reading unit 13 from the block 14 is performed by the response digit switching unit 9.

By filling in the input of all the bits that make up the answer for each question, pressing the "Total on the work console" button gives a signal that, similarly to the signal about the discharge of the answer, is sent through block 6 allowing the input of the answer, block 4 of the response bit memory in block 8 is a bit comparison comparison response.

In the latter, each bit that constitutes the content of the answer and the signal that the response is completed is compared with the corresponding signals from block 14 but the specified question number through block 13. At the time a bit mismatches, which is regarded as input perversion Inaccurate response, including the mismatch of the signal about the end of the answer, in block 10 the mismatch results in a signal to prohibit the issuance of the final block

Commands to turn on a warning light information board 16.

The prepared signal light corresponding to the question number for which the answer was entered is not illuminated in this case. This means that the answer was incorrect.

If in the process the compared signals did not occur, the prohibition signal is absent and on the information board 16 the signal lamp lights up corresponding to the question number, but to which the correct answer was entered. On the signal “The result, but nostunilov in block 11, in the nose with a slight delay in relation to the signal to turn on the signal light occurs

the reset signal of the memory of the entered question number in block 3 gives us the question number, which allows the user to go to the answer for any other question included in the start number of the letter.

In the course of the operation mode switching unit 15, two positions are possible according to the presentation of light information on the results of the work of each student.

In the first position, the signal is postunew.

from block 11 of forming the final team, in the case of the correct answer, it is given to the information board of 16 trainees which ensures the inclusion of a signal lamp corresponding to the number of the question that was given

the answer (according to the ticket number assigned to the working console). When entering unbelievable response, the warning light does not turn on.

Immediately signaling whether the entered answer is correct or not is necessary in

modes "Self-control and" Training. The sequential switching on of the indicator lights on the information board 16 serves to confirm that the sequence of actions chosen by the student is correct.

In the second position, the signal from the final command generation unit 11 to the information board of the students 16 prepares the signal light to turn on for each correct answer. The inclusion itself comes at the end of the work of all the students: the first by the sigal, iodavodomu teacher from the block 15 switching modes. The considered procedure for issuing light signaling about the results of students' work is used in the "Control.

Light signaling about the number of correct answers given from each of the work consoles of students 1 according to the ticket numbers assigned to them serves as a basis for the teacher to make a corresponding assessment.

Information board 17 allows the teacher to check at any time what ticket number the student from his work desk enters the answers. This check prevents the teacher from learning how to use the ability to enter correct answers according to a ticket that was prepared in advance, and not according to the number of the ticket issued to him by the teacher.

The information board nrenodavatell 17 contains:

- indicator of ticket number for two decimal places (for example, on digital indication lamps or luminescent indicators) - one for all workplaces;

- a switch for selecting the operating mode of the information board of students 16, which allows to select the mode of immediate or delayed release of information about the results of the student’s oteeTOB;

-buttons for resetting the ticket number recorded in block 2 to us or ticket number, and not resetting the information boards of the 16 students to the initial position after fixing the responses of the student.
