A Web-Based Collaborative Learning System

Computer Aided Education (CAE) is one of the most important methods of modern educational technology. The Internet and the World Wide Web (WWW) have provided a wider context for this field, which has already attracted a lot of attention. In the early 1990s, the Constructivist Theory of Education and Collaborative Learning were introduced, which emphasize student-centered instruction. This paper discusses relevant topics in this field, including architecture, logical design, interface design, implementation strategies and maintenance. The discussion is based on a real project named SIM-EDI, which simulates an Electronic Data Interchange (EDI) system and provides many useful functions for students and instructors. This system was completed two years ago and has been installed in several sites located in different cities, with good result As conclusions, several suggestions for this field have been provided at the end of the paper.
