SU427372A1 - DEVICE FOR ASSESSING RESPONSES OF STUDENTS - Google Patents

Description

one

The invention relates to the field of automation and computer technology and can be used in control and training machines.

Apparatus for evaluating student responses is known, comprising a response input unit, a software unit and a response determination unit.

However, in such devices, the complexity of the circuit for determining the location of errors depends on the variety of response codes and their number. To simplify the design, limit the number of students' knowledge control programs.

The purpose of the invention is to eliminate these disadvantages and simplify the design of the device.

This goal is achieved by the fact that the program block contains contact tires and moving contacts. (Moreover, the outputs of the response input unit are connected with movable code-contacts, and the inputs of the error location determination unit are connected to the contact blocks of the program block.

This is provided at the input of the error location unit. The sequence of signals is correct. With the right answer.

The complexity of the circuit for determining the location of errors does not depend on the set of control programs, and the scheme is simplified, since in this case there is no need to include elements of analysis of various combinations of input signals, it is only necessary to detect and indicate the location of the error.

FIG. 1 is a diagram of the device; in fig. 2 - program block.

The device consists of a response block 1, a software block 2, and a block for determining the location of errors 3.

The program block 2 contains a removable software punch card 4 with holes 5, movable contacts 6 and contact buses 7.

The device works as follows.

The response code is entered sequentially bit by bit from the block / into the program block. If the answer is correct, the program block converts a disordered sequence of pulses at its input into a sequence of pulses when the first pulse appears on the first output bus of the program block, the second pulse on the second bus, and so on.

TaiHHM way, on the input block defined30 place of error for any response code

always ordered sequence of pulses.

The program block converts the irregular sequence of pulses into the ordered as follows.

The control programmer, using the well-known Correct Response Code, determines the sequence of numbers of the input buses of the program block on which the pulses should appear when entering the correct answer. In this sequence, he arranges the intersection positions of the input and output shi, where it is necessary to ensure contact of the first, second, and so on output tires, and on the punched card the punching of the holes at the indicated positions. As a result, the moving contacts are closed with those contact tires at the position of which the card has perforation - a hole.

In this case, the first impulse coming from the response input unit to any number of moving contacts appears on the first contact bus, the second impulse on the second bus. In case of an error in one of the response code bits, the standard sequence of pulses at the output of the program block is violated, and the error locator determines the number of the contact bus of the program block on which the sequence is violated.
