Abstract
The online computer-assisted instruction system has changed the way of knowledge acquisition, and makes knowledge transmission faster, and more con-venient and efficient. This study discusses the key technologies of online com-puter-assisted instruction system with such methods as literature research, system analysis and empirical research, analyzes the requirement of online computer-assisted instruction system with object-oriented analysis method, determines the main functions of online computer-assisted instruction system, and designs the model of online computer-assisted instruction system in detail with the aid of UML technology. The practicality and validity of the model are verified by the re-alization of some interfaces and processes of the system model.
Highlights
The continuous development of modern information technology provides new possibilities for education and teaching reform while making people acquire knowledge more widely
The online computer-assisted instruction system has changed the problem that the traditional teaching mode is limited by the time and place of class, and realized that the students can study at any time and place, which mainly depends on the network technology and the communication technology
In order to make up for the problems such as limited teaching time and insufficient teaching guidance in traditional classroom teaching, this study makes a detailed analysis of the user demand and function demand of the online computer-assisted instruction system with object-oriented analysis from the point of view of students and teachers
Summary
The continuous development of modern information technology provides new possibilities for education and teaching reform while making people acquire knowledge more widely. Computer assisted instruction is an important symbol of educational modernization. The rapid development of network provides a new platform for innovation of educational technology, ideas and means, and lays a solid foundation for online assisted instruction. With the development of all kinds of theories and technologies, computer-assisted instruction has developed rapidly and popularized from primary school to adult education. Development of online computer-assisted instruction system, and changes the traditional concept of teaching and management [3]. The State attached great importance to this, and increased the policy support for online computer-assisted instruction and related capital investment. It can be said that it’s the era that the online computer-assisted instruction entered the education field and cause a major change in education. Function description and detailed design of the online computer-assisted instruction system, this study verifies the practicality of the model by the realization of the system interactive interface and online examination system
