Abstract
The Internet breaks the limitations of time and space and provides a flexible platform for learning, Learning is a two-way communication and interactivity is a process to enhance communication among instructors, learners, learning materials, and interfaces. However, little studies exist regarding the effect of WBI interactivity on learners ' performances and attitude. This research examines how different degrees of WBI interactivity influence learners ' attitude, satisfaction, and performance in using the WBI systems. The results will provide useful applications for WBI designers and instructors. © 2005 IEEE.
