Computer-aided test (Computer-aided test) refers to a method using computer-assisted testing. Computer-aided testing can be used in different fields.

In the teaching field, computers can be used to test students' learning effects and measure their learning ability. Generally, there are two methods: offline testing and online testing.

In the field of software testing, computers can be used to test software and improve testing efficiency.

Computer Aided Test Definition

The offline test is that the computer selects a set of appropriate questions from the preset question bank according to the requirements specified by the teacher, prints them as test papers, and after answering to the students, the answer card can be sent to the computer through the "optical reader" Mark and score. Standard answers are stored in computers for comparison.

On-line test is to select questions one by one from the computer's problem library, and ask students questions through interactive means such as monitors and output printers. They send their answers to the computer through input devices such as keyboards, which are reviewed and graded by the computer. One of them is called an adjustable test. The computer can determine the difficulty of the next step based on whether the student answered correctly or not. According to the law of education statistics, only a small number of questions and answers can be used to determine the student's learning status. .

Computer-assisted testing, also known as computer-aided testing (CAT), is composed of five parts: test composition, test implementation, grading and analysis, test question analysis, and question bank. It focuses on explaining that each part has different functions and functions in the entire system, and finally summarize .

Computer Aided Test Composition

(A) the composition of traditional tests

In traditional teaching, in order to prepare a quiz, teachers often have to make some rules: In order to facilitate management and distinguish different levels, how many questions should be tested in a valid time? What concepts are tested? How many questions are there for each concept? Need to answer? How many objective questions are there? How many quiz questions are there? Among the objective questions, how many are false? How many multiple choice questions are there? How many matching or blank questions?

Based on these rules, teachers begin to form individual questions or groups of questions from the selected test questions.

In general, constructing a quiz is a manual process for teachers. For each new quiz, the unconnected teacher repeats the whole process from the beginning. To reduce the preparation process, teachers save quiz questions year after year.

(II) Composition of computer-assisted testing

Today, with computer-assisted testing, the composition of the test is the same as that of the traditional test, but the entire process has been considerably simplified and improved. Computers can randomly construct test papers as required. Whether it is the matching of question types, the distribution of scores, or the determination of time, it is very accurate.

Computer Aided Test Implementation

When the quiz sending process is an independent system, it must include the quiz composition and the question bank, but there may be fewer questions in the question bank. This stand-alone system is suitable for unit quizzes of courses.

If there are enough computer terminal systems available, students can be tested through the terminal, which has many advantages:

1. Because the computer knows which questions to test the students and can remember the answers to the questions. So the order of the questions is irrelevant.

2. Because the computer can support printing, grading, and convenient handling of various problems, the examination papers can be omitted.

3 In a system with an internal clock, students are allowed to take individual tests within a certain period of time. If the tests are given to the students in the same format and have the same time limit, students with different degrees will receive different questions.

4 During the test, students can get feedback in time, and once the test is over, they can get test results and grades.

In addition, the online quiz also supports adaptive quizzes, and many people are researching experiments to implement adaptive quizzes by computers.

Computer-assisted testing terminology

CAT: Computer Aided Testing

A special term for the machinery industry, which means that various parameters of parts are collected and processed by a computer to verify whether the parts meet the processing or assembly requirements.
