An evaluation model for Web-based instruction

Recently Web-based instruction (WBI) has been adopted for many educational systems in order to support distance education. WBI has become popular in that it overcomes time and space limitation in traditional educational systems. But due to lack of face-to-face communication, it is crucial that WBI provide interactivity and motivation for students. This paper introduces a formal model that evaluates interactivity and motivation for courses based on WBI. The model is comprehensive and objective so that it can be used to evaluate any course. Based on the model, the paper selects some WBI courses and compares them for their interactivity and motivation. Finally, the paper concludes with a discussion of further research issues.
