Design and implementation of the online computer- assisted instruction system based on object-oriented analysis technology

Abstract

The online computer-assisted instruction system has changed the way of knowledge acquisition, and makes knowledge transmission faster, and more convenient and efficient. This study discusses the key technologies of online computer-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 realization of some interfaces and processes of the system model.
