Conceptual network based courseware organization and navigation

We present a conceptual network model for the organization of courseware and the related information. Using the hierarchy and association rules of the concepts, we organize components and courseware episodes as a multi-layer knowledge network, which has a reasonable classification and discloses the complicated interdependent relations among the knowledge. With retrieval based on concept and association among concepts, people can manage and develop courseware, and lead the course for self-organizing and study.
