It is a hierarchical tree for developing the interrelations among learning concepts. Each learning concept is stored as a concept node in the dynamic conceptual network. A concept node includes contents, tasks, and attributes. The contents are represented by text, graphs, audio, and/or video, and these contents are stored in a knowledge base.

Abstract
To cope with the increasing trend of learning demand and limited resources, most universities are taking advantage of Web-based technology for their distance education or e-learning (Montelpare & Williams, 2000). One of the reasons is due to the significant price drop of personal computers in recent decades; the Internet and multimedia have penetrated into most households. Moreover, most students prefer to learn from an interactive environment through a self-paced style. Under the Web-based learning model, students can learn anytime, anywhere because they are not required to go to school on schedule (Appelt, 1997). Meanwhile, universities also enjoy the economic benefit due to the large student base that can share the development cost of course materials and other operational expenses. Gradually, more and more universities follow this similar way to provide online education.
