The invention relates to automation and computing, in particular to devices for the automated control of students' knowledge.

The aim of the invention is to expand the didactic capabilities of the device by providing the ability to control knowledge on issues that do not have a strictly standard answer.

FIG. 1 shows a block diagram of a device for monitoring students' knowledge; in fig. 2 is a block comparing input with key words: in FIG. 3 - block of the analysis of answers; in fig. 4 and 5 are variants of the connection of the triggers of the block of triggers.

The device for controlling students' knowledge contains a block 1 for entering answers, consisting of 1, iy of buttons, the number of which is equal to the number of different elements (letters, numbers) from which can be composed: answers to questions (besides block 1, input of answers contains a button the end of the word input and the end button of the input answer: veta), block 2 triggers, a set of triggers, each of which is connected to block m 1 of input of answers, block 3 of the response code, block 4 of memory. standard answers, blocks 5 comparisons entered. Words with reference, b locks 6 pa.ty typing results of comparison of entered words with reference ones, block 7 of response analysis, block 8 of indication.

Block 3 is a collection of well-known, for example, photoelectric sensors, by impassing key words into block 4 from a storage medium, for example, from a film. Blocks 4 are sets of triggers whose inputs are associated with block 3 (not shown in Fig. 2).

Blocks 5 for comparison of the entered word with key words (see Fig. 2) are performed on the elements AND 9, 10, OR 11, and 12. Block 6 of the memory of the results of the comparison can be implemented on a trigger. Block 7, depending on the pedagogical tasks, can be performed on the AND element or on the OR element, and it can also simultaneously contain e, 1 AND elements and OR elements. Block 8 of processing data about the answers is performed on the counter of correct answers and the counter of the total number of questions answered. Consistently with each counter, a decoder and a device for the contents of the counter content are turned on (block 8 is not disclosed in the diagrams, since it is made according to known implementations). To set block 2 to the zero position, after completing the input of the word and the answer, the element OR 13 is used, which is connected to the buttons for the end of the word and the input for the answer, located in 1, and the time delay element 14. To set blocks 6 to zero position after windows 0

The answer to the question is using the time delay element 15 connected to the end button of the answer located in block 1 (the circuit for setting the device elements to the initial state is not shown in the diagram).

The device for the control of students' knowledge works in the following manner.

Quiz questions are written text located on a storage medium, such as a film. They are automatically projected on the screen of the controlling machine and are replaced upon completion of the answer to this question. On the information carrier (on each frame of the control question), there are marked reference response codes, which are not projected on the screen, and through the unit 3 inputting reference responses on the signal from block 1 (but the signal from the end button changes the question frame and the code is recorded etalopic answers) is recorded in memory blocks 4, and in response to this question, the student builds his answer from the words typed to: 1) (using buttons) b. | 1ka I. Each 5th typed word is entered into a box 2. 2. When the word is completed, the 1st signal from block 1 (but the signal from the end of word input button) in blocks 5 is a bit of a comparison of the contents of block 2 and the contents of blocks 4 ti. When the contents of block 2 coincide with the contents of one of blocks 4 at the output of the AND 12, a signal appears, which is memorized by block 6, otherwise the signal at the output of the AND 12

r does not occur. As a result of the entire answer set in blocks 6, information will appear, but which can be judged on the correctness and completeness of the answer to the question posed. For example, in the absence of signals from all blocks b. You can conclude that the answer

 done wrong. In the absence of a signal at the output of at least one of the blocks 6, it can be concluded that the answer is incomplete. Thus, the response analysis block 7, depending on the depth of the analysis, can be performed on the AND element or the OR element, and can also simultaneously contain the AND elements and the OR elements whose inputs are connected to the blocks 6 and the outputs of the block 8 indications. From block 8 (from the corresponding counters of correct answers,

0 incorrect answers, incomplete answers) information on the completion of the tasks of control tasks is removed.

Block 7 in this case contains the first element AND 16, the first element OR 17, the switch 18 completeness of the answer to the question, the second element OR 19, the second element AND 20 (Fig. 3). Completeness Inputs

answering a question whose role is played by trigger f is connected to the keyword input unit 3 (this connection is not shown in Fig. 1) The first output of the answer answer switch to the question through the first element AND 16 is connected to the first output of the second element OR 19 , the output of which is connected to the response data processing unit 8, the second output of the answer answer switch to the question through the second element AND 20 is connected to the second input of the second element OR 19. The second input of the first element AND 16 and the second element AND 20 are connected to block m 1 input answer (with an eye button nchani input answer). The inputs of the first element OR 17 and the remaining inputs of the first element AND 16 are connected with the corresponding blocks 6 of the memory of the results of the comparison of the entered words with the key. The third input of the second element AND 20 is connected to the output of the first elementa OR 17.

Block 7 works as follows.

On the information carrier, for example, on film, along with the reference response codes, the position code of the switch 18 for completeness of the answer to the question that is not projected on the screen is recorded on each control frame, and through the unit 3 inputting the reference responses on the signal from block 1 (and the signal the answer stop button changes the frame with the question, the code of the reference answers is written and the switch 18 is set to a certain position) the switch 18 is set to the position at which the first input of the AND 16 element appears I drove (if .dl correct answer must use keywords), or a position in which the first input of the second AND gate 20 will be the signal (if for the right answer to the question is sufficient to use only one, and any keyword). In the first case, the device 7 will receive a signal at block 8 after the end of the answer, if all the keywords are used in the answer. In the second case, the device 7 will receive a signal at block 8 after the end of the response if at least one keyword is used in the response.

If block 2 is made of unintegrated triggers, the device cannot control the sequence of input elements. To ensure control of the sequence of input elements of the response in block 2, at least the counting input of one trigger is connected to the single or zero input of another trigger.

FIG. 4 shows two triggers with additional connections that allow for accounting

sequences of characters entered. So, if the numbers a and b are entered into the trigger in the ab sequence, then the code 01 is removed from the trigger unit, and if it is in the LA sequence, we remove the code 10 from the trigger output unit (initially, the trigger is set to zero position).

FIG. Figure 5 shows another variant of the organization of additional links that take into account the sequence of input characters. If the numbers c and d in the sequence cd are entered into the trigger, then we remove code 10 from the single outputs of the trigger, and if in the sequence dg, then we remove code 01 from the outputs of the trigger.

The advantage of the proposed device is the ability to control knowledge on issues that do not have a strictly standard answer.
