Description

Изобретение относится к автоматике и вычислительной технике, в частности к техническим средствам обучения, и может быть использовано при организации программированного обучения в различных учебных заведениях.The invention relates to automation and computer technology, in particular to technical teaching aids, and can be used in organizing programmed training in various educational institutions.

Известно устройство для контроля знаний учащихся, содержащее пульты учащихся, коммутатор пультов, блоки эталонных ответов, оценки, индикации и управления [1].A device for monitoring student knowledge, containing student remotes, remote commutators, blocks of standard answers, assessment, indication and control [1].

Однако это устройство не позволяет осуществлять интегральную оценку знаний группы учащихся.However, this device does not allow an integrated assessment of the knowledge of a group of students.

Наиболее близким техническим решением к изобретению является устройство, содержащее пульты учащихся, подключенные к входам матричного распределения, выходы которого соединены с входами блока определения процента правильных ответов по отдельным вопросам и с входами блока определения процента правильных ответов по всем вопросам, выходы матричного распределителя соединены также с входами блока оценок, выход которого подан на вход блока определения среднеарифметической оценки и на вход блока определения процентного соотношения оценок. Однако эффективность устройства не высока, так как в нем не учитывается время, затраченное на подготовку ответа учащимся. Ввиду того, что момент начала контроля (начала циклического опроса) 5 определяется преподавателем, то возможны колебания в оценках у одинаковых по подготовленности групп учащихся из-за разброса времени на подготовку (времени от момента получения учащимися вопросов до момента начала контроля [2].The closest technical solution to the invention is a device containing student panels connected to the inputs of the matrix distribution, the outputs of which are connected to the inputs of the unit for determining the percentage of correct answers for individual questions and with the inputs of the unit for determining the percentage of correct answers for all questions, the outputs of the matrix distributor are also connected to the inputs of the evaluation unit, the output of which is fed to the input of the arithmetic mean definition unit and to the input of the percentage determination unit . However, the efficiency of the device is not high, since it does not take into account the time taken to prepare the answer to the students. Due to the fact that the moment of the beginning of control (the beginning of a cyclic survey) 5 is determined by the teacher, there may be fluctuations in the assessments of groups of students with the same preparedness due to the spread of time for preparation (time from the moment students receive questions to the moment the control begins [2].

¹⁰ Целью изобретения является повышение точности устройства. ¹⁰ The aim of the invention is to improve the accuracy of the device.

Достигается это тем, что в известное устройство, содержащее пульты учащихся, подключенные через коммутатор пультов к блокам определения процента правильных ответов по всем вопросам и по отдельным вопросам и к блоку оценки ответов, соединенному с блоками определения среднеарифметической оценки и процентного соотношения оценок, введены блок контроля времени 20 ответов, блок определения количества ответов и последовательно включенные генератор, формирователь пусковых сигналов и датчик временных интервалов, который соединен с. формирователем пусковых сигна736158 лов и блоком оценки ответов, подключенным к блоку контроля времени ответов, формирователь пусковых сигналов соединен непосредственно с коммутатором пультов, блоком оценки ответов и блоками определения процента правильных от- ₅ветов по всем вопросам и по отдельным вопросам, а через блок определения количества ответов — с коммутатором пультов.This is achieved by the fact that a control unit has been introduced into the known device containing student panels connected via the panel switch to the units for determining the percentage of correct answers for all questions and for individual questions and to the unit for evaluating answers connected to the units for determining the arithmetic mean rating and percentage of ratings 20 response time, a unit for determining the number of responses and a series-connected generator, a trigger driver and a time interval sensor, which is connected to. generator launchers signa736158 catching unit and evaluating the responses that are connected to the control unit, time responses of the start signal generator is connected directly to the switch consoles, responses and the evaluation unit determining the percentage of correct blocks ₅ The relative quick advice on all matters and specific issues, and by determining the number of block Answers - with the remote control switch.

Nodes 5, 7, and 8 represent a switchboard of consoles 15.

Устройство для контроля знаний учащихся работает следующим образом. ²⁵ A device for monitoring student knowledge works as follows. ²⁵

Перед началом контроля преподаватель устанавливает вручную на блоке 3 время ответа на каждый вопрос, а на датчике 6 временных интервалов — минимальное и максимальное время ответов. Далее препода- ₃₀ватель выдает вопросы и включает устройство. По истечении минимального времени ответа сигнал с выхода датчика 6 временных интервалов через формирователь 4 включает распределители 5 и 7 (начинает пропускать на вход распределителя 5 импульсы от гене- 35 ратора 1). При этом начинается циклический опрос пульта 2 учащихся.. При наличии правильного ответа на какой-либо вопрос на одном из пультов 2 учащихся, код ответа через логические элементы И-ИЛИ 8 поступает в блок 12 определения процента пра- ⁴⁰вильных ответов по отдельным вопросам, в блок 10 определения процента правильных ответов по всем вопросам, в блок 11 оценки ответов. В блок 11 поступает также код времени, затраченного на подготовку от дат- 45 чика 6 временных материалов. Кроме этого, код ответа поступает в блок 9 определения количества ответов, где фиксируется количество полученных ответов. Циклический опрос пультов 2 учащихся продолжается ли бо до ответа на вед вопросы всеми учащимися ( в этом случае, сигналом с выхода блока 9 определения количества вопросов выключается формирователь 4), либо до истечения максимального времени отвесов, в этом случае формирователь 4 выключается сигналом с выхода датчика 6 временных интервалов.Before starting the monitoring, the teacher sets manually on block 3 the answer time for each question, and on the sensor 6 time intervals - the minimum and maximum response time. Then the teacher asks ₃₀ questions and turns on the device. After the minimum response time has elapsed, the signal from the output of the sensor 6 time intervals through the former 4 includes the distributors 5 and 7 (it starts to transmit pulses from the generator 35 to the input of the distributor 5). Thus begins the cyclic poll panel 2 pupils .. If there is a correct answer to a question on one of the panels 2 students, the response code via the AND gates, OR 8 is passed to block 12 to determine the percentage pra- ⁴⁰ right answers on specific issues, in block 10 determining the percentage of correct answers for all questions, in block 11 of the assessment of answers. Block 11 also receives the code of the time taken to prepare from sensor 6 of temporary materials. In addition, the response code is sent to block 9 for determining the number of responses, where the number of received responses is fixed. A cyclic survey of the panels for 2 students continues until all students answer the questions (in this case, the shaper 4 is turned off by the signal from the block 9 for determining the number of questions), or until the maximum plumb time expires, in this case the shaper 4 is turned off by the signal from the sensor output 6 time intervals.

После окончания опроса пультов 2 учащихся блок 11 на основе количества правильных ответов и времени, затраченного на подготовку ответа учащимся, определяет оценку. По сигналу с выхода формирователя 4 блоки 10—14 индицируют полученные результаты.After the survey of the remotes of 2 students is completed, block 11 determines the assessment based on the number of correct answers and the time taken to prepare the answer for the students. The signal from the output of the shaper 4 blocks 10-14 indicate the results.

Таким образом, предложенное техническое решение, в отличие от известных, позволяет при определении оценки учесть длительность подготовки учащихся, а также, вследствие автоматизации отсчета времени с момента начала опроса, более объективно оценивать знания учащихся.Thus, the proposed technical solution, in contrast to the known ones, allows taking into account the duration of students 'preparation when determining the assessment, and also, due to the automation of the countdown from the moment the survey began, more objectively evaluating students' knowledge.

Claims

The invention relates to automation and computer technology, in particular to technical means of training, and can be used in the organization of programmed training in various educational institutions. A device is known for controlling knowledge of students that contains student's consoles, switchboard of consoles, blocks of reference answers, evaluation, indication and control 1. However, this device does not allow an integrated assessment of the knowledge of the group of students. The closest technical solution to the invention is a device containing student consoles connected to the inputs of the matrix distribution, the outputs of which are connected to the inputs of the percent correct answers module for individual questions and the percent of the correct answers for all questions outputs of the matrix distributor They are also connected to the inputs of the assessment unit, the output of which is fed to the input of the arithmetic average estimation unit and to the input of the percentage determination unit nok. However, the effectiveness of the device is not high, since it does not take into account the time spent preparing the answer to students. Due to the fact that the beginning of the control (the beginning of the cyclical survey) is determined by the teacher, there may be fluctuations in the assessments of groups of students with the same preparedness due to the variation in training time (in-time from the moment students receive questions until the control starts 2.) of the invention is to improve the accuracy of the device. This is achieved by the fact that, in a known device containing learning consoles, connected through the switchboard of the consoles to the units for determining the percentage of correct answers for all questions and individual questions and a response evaluation unit, connected to arithmetic mean and percentage estimates, determine the response time block, answer number determination block and sequentially connected generator, trigger generator and time sensor, which is connected to the trigger generator and the block response evaluation, connected to the response time control unit, the trigger driver is connected directly to the switchboard, the unit evaluation of answers and units for determining the percentage of correct answers for all questions and for individual questions, and through the unit for determining the number of answers with a switchboard. The drawing shows a block diagram of a device for monitoring students' knowledge. It contains the generator 1, remote controls 2 learners, block 3 controls the response time, shaper 4 trigger signals, distributor 5 question numbers, sensor 6 time intervals, distributor 7 numbers of remote controls, AND-OR elements 8, block 9 determining the number of answers, block 10 determining the percentage of correct answers for all questions, the evaluation evaluation block 11, the determination block 12 for the percentage of correct answers for individual questions, the arithmetic mean rating determination block 13 and the percentage estimate rating block 14. Nodes 5, 7, and 8 are a switchboard of the consoles 15. A device for monitoring students' knowledge works as follows. Before starting the control, the teacher sets manually on block 3 the time for answering each question, and on the sensor 6 time intervals - the minimum and maximum response times. Further, the teacher issues questions and turns on the device. After the minimum response time, the signal from the output of the sensor 6 time intervals through the imaging unit 4 turns on the valves 5 and 7 (it starts to transmit pulses from the generator 1 to the input of the distributor 5). At the same time, a cyclic polling of the first two learners begins. If there is a correct answer to a question on one of the 2 student learners, the response code through logical AND-OR 8 instructions comes in block 12 to determine the percentage of correct answers on individual questions , in block 10, determining the percentage of correct answers for all questions; in block 11, evaluating the answers. In block 11 also receives the time code spent on preparation from the sensor 6 temporary materials. In addition, the response code arrives at block 9 for determining the number of replies, where the number of replies received is recorded. Cyclic polling of the student consoles 2 continues either BEFORE the answer to BCi questions by all students (in this case, the signal from the output of the number-determining unit 9 B): IJ) OCOB shaper 41, .ni6o turns off before the maximum time 1 and offshoots, in this case shaper 4 is turned off by a signal from a sensor output of 6 time slots. Upon completion of the survey of the student consoles 2, unit 11, based on the number of correct answers and the time spent preparing the answer by the students, determines the assessment. The signal from the output of the imager 4 blocks 10-14 indicate the results obtained. Thus, the proposed technical decision, in contrast to the known ones, makes it possible to take into account the training duration of students, as well as, due to the automation of time counts since the beginning of the survey, to more objectively assess the knowledge of students when determining the assessment.
