(54) DEVICE FOR CONTROL OF KNOWLEDGE OF STUDENTS

The invention relates to teaching aids, in particular to devices for programmed knowledge control, and can be used in a training system. A device for controlling students' knowledge is known, in which the preprepdator console contains a keypad for entering correct answers, allowing him to ask a student a question in a lecture mode, and enter the correct answer to it from the specified keyboard and then by quantifying the correct and incorrect answers received from learners to determine the degree of assimilation of the material presented by them 1. However, the known device does not allow for the possibility of carrying out boundary control by asking a series of control questions on the study Subject section, topic, and so on. To conduct such a survey, the teacher is taken to enter the correct answers to each asked question after receiving data on the results of the answer to the previous one. Since all students learn the right answer to iiotvvaB.ieHHbm the question is ONE and same, the reliability of the boundary control of knowledge decreases. It is also known a device containing a teacher’s console, a program block for specifying response codes and a response input panel by a teacher 2. The drawback of the device is that it contains a special keyboard for entering answers; After working out the question, the correct answer to which is entered from a special keyboard, the teacher must reset the keyboard with a special button. If he forgot to do this, then for the next question the correct answer comes from the keyboard, the correct answer is not the key, and not from the coding block. Closest to the proposed technical entity is a device containing response input consoles.

job numbers, code distributor, switch of response channels and reference codes 3

Before starting to occupy the code field of the coding block, the teacher exposes back codes that can be issued during the verification process. With the help of the code distributor, a series of reference codes is established for each workplace from which the trainee will answer control tasks. Thus, it is possible to carry out the midterm control with a sufficiently high reliability. However, if in the course of conducting an occupation, the teacher needs to quickly control the degree of assimilation of the stated material, he is forced to transcode the reference answers from one of the questions (with the corresponding changes in the code distributor switching ), and before conducting the boundary control, restore the paihee prepared program of standard responses. These actions lead to unproductive time spent by the teacher, reduce the effectiveness of the use of the device, limit its scope.

The purpose of the invention is to improve the didactic capabilities of the device by ensuring that both frontal polling and mid-term monitoring are carried out with minimal time spent on changing the reference response code.

This goal is achieved in that a device containing student consoles is connected via a switchboard to an answer comparison unit connected to a random access memory unit that is connected directly and through the evaluation unit to the indication unit, as well as to the control unit and the coding unit, connected to the switchboard of the consoles, which is connected to the control unit connected to the control unit, a task switchboard, a register and a trigger connected to the control unit, the switchboard of task standards and a control panel connected via a register to a task reference switch connected to the comparison and encoding comparison blocks.

The drawing schematically shows a device for monitoring students' knowledge.

The device contains student consoles 1, display unit 2, evaluation unit 3, switchboard 4, memory block 5, comparison unit 6, control unit 7, control panel 8, job reference switch 9, flip-flop 10, encoding unit None register 12.

The console 8 allows the teacher to control the operation of the device as a whole and carry out a reference response to the question posed during the presentation of the material. The control unit 7 synchronizes the operation of the main nodes of the device in accordance with the modes specified in the keyboard unit. Switch 4 accepts requests for processing responses and the responses themselves received from consoles 1. Block 6 compares the codes of reference answers and answers received from students through switch 4. Block 5 stores information about the correct and incorrect answers given to each student for each question the task, the number of students who answered and answered correctly for each question of the task, the number of questions worked by each student, the time elapsed since the beginning of the study of a given question. Unit 3 calculates an assessment for each student based on data obtained from unit 5 on the number of questions asked and the number of correct answers to them. Unit 2 displays the results of the work of each student and his assessment, the current time, the number of the question being worked out by each student or the group as a whole. Coding block 11 allows the teacher to set the correct answer codes for a series of questions and assign each student or group a corresponding task, consisting of a series of reference answers. Register 12 is used to store the code of the answer for one question. The switch 9 connects to the input of the comparison block 6 either the output of the coding unit NIL 11 or the output of the register 12 depending on the state of the trigger 10.

The device works as follows.

In the initial state after turning on the power, the state of the trigger 10 is such that the switch connects the output of the coding block 11 to the input of the comparison block 6.

Claims (3)

Before starting the lesson, the teacher enters the standard answers in the coding flea 11. At the right moment, the teacher using the remote control 8 allows the students to answer the proposed questions in group or individual order, depending on the mode set by the keyboard unit. The student, who has prepared the answer to the question, enters it using the keyboard of the remote control 1, and then presses the ready answer button. Switch 4 continuously polls the states of the readiness buttons of the control panels 1 and, if there is a ready signal, stops further polling, simultaneously transmitting to the coding unit 11 and block 5 through the control unit 7 a console number and connecting the output of the console I to the input of the comparison unit 6. Correct answer code the corresponding question number from block 5 enters from coding block II through switch 9 into block 6 and compare 6. The result of the comparison goes to block 5 and causes the measurement of the states of the corresponding response counters. 56 correct answers and so on. The state of block 5 and the block 3 associated with it is displayed by block 22. Switch 4 after processing the answer selected by the teacher, allows the input of the next answer to be entered or disables it and again goes to Scholarly polling the readiness buttons of the consoles 1. If the teacher needs to use the device in lecture mode for frontal polling, it from the remote control 8 in a convenient form introduces a reference response, which is recorded in register 12. Simultaneously with entering the code of the standard response in register 12, trigger 10 changes its state the opposite, and to the input of the comparison block 6, the switch connects the output of register 12, regardless of the state of the outputs of the coding block I. The teacher allows the students to enter their answers, but now they are all compared with the reference answer stored in register 12. After the specified time, the device automatically or at the command of the teacher, observing the number of answers and the number of correct ones displayed by block 2, stops polling, while from the control unit 7 a signal is received that translates the trigger EP 10 is reset to its original state, re-connected to the input of the comparator unit 6 the output of the coding unit 11. The proposed device for the group. control of knowledge allows the teacher to conduct a quiz of the trainees by asking a series of questions, as well as to quickly control the mastery of the material by the audience as a whole during the presentation, without violating the pre-established program of monitoring the 9th survey, while reducing the operator’s actions with the controls, which significantly simplifies the operation of the equipment, increases the coefficient of its use and the time of the teacher and ultimately allows to improve the quality of training.
