An intelligent, multimedia-supported instructional system

摘要

This article describes the design of intelligent features in the instructional system Intelligent Computer-Assisted Instruction for Computer Engineering (ICAI-C), which was developed for supporting computer instruction at the Nanyang Technological University, Singapore. The ICAI-C system supports a set of coursewares for teaching and learning various computer engineering subjects. It generally provides multimedia-supported lessons, exercises, tests, feedback on students' performance and progress, as well as discourse moderation in an interactive and adaptive manner. The system architecture, instructional design, student modeling, and knowledge-base organization are described. The system architecture consists of an intelligent hypermedia interface, a CAI (computer-assisted instruction) shell, and a hyperbase. The hyperbase was designed to integrate all the data, knowledge, and multimedia objects used in the instructional process.
