Structure of an Internet-based CAL system

Dayou Li.

Computer Assisted Learning (CAL) encourages active and creative learning by providing computer-based interactive teaching and learning facilities. The Internet is flexible with respect of resource access and facilities communication, enabling the Internet-based CAL to remote access up-to-date teaching materials and to enhance interactivity. The Internet-based CAL is also able to provide a variety of representations to satisfy students from different backgrounds. It is a new attempt towards active and creative learning.

The paper presents structural considerations regarding the functional and non-functional requirements of an Internet-based CAL system for the subject of Object-Oriented System Development. The non-functional requirements include the enhanced interactivity, the variety of representations and the encouragement of active and creative learning. The system consists of a lecture notes module, a case study module, an exercise module and a virtual chat room. Students need to work out their solutions to given problems and to verify the solutions, rather than passively read and accept model solutions. The students and tutor can discuss problems in the chat room. The system also contains a database to store teaching materials and students records. One of items of the record is a student’s culture/background which can be used to deliver the most suitable teaching material to the student. The system provides an interface to an intelligent searching and decision-making mechanism that would be able to collect information on students’ culture/background through the Internet.
