Keywords:constructivism, online, assisted instruction, object-oriented analysis technology, UML
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.
