Authoring and Delivering Adpative Web-Based Textbooks Using WEAR

In this paper, we describe the adaptive courseware authoring capabilities of WEAR, an ITS authoring tool for Algebra-related domains. The system allows the authoring of electronic textbooks and delivers them over the WWW. Then learners are offered navigation support adapted to their individual needs and knowledge. The domain knowledge and the information kept in learner models are used in WEAR to provide adaptive navigation to students and also to support the instructional designers in the authoring process. An instructor model incorporated in WEAR’s architecture contains additional information that is exploited by the system to achieve the goal of authoring support.
