A New Adaptiveness Model in Learning System Based on Learner Context

摘要

Adaptive learning system must support different learning objectives and contexts of different learners. However only a very limited requirements above can be considered in present adaptive learning systems, especially in learning objectives. By extending the domain model and the user model and introducing the directed hypergragh theory in learning system, three types of adaptiveness to the user model: learning objective adaptiveness, learning navigation adaptiveness and learning content adaptiveness in learning system are defined formally, analyzed in detail, and implemented arithmetically. The research shows that three types of adaptiveness to the user model in learning system above can support the adaptiveness to different leaning objectives and styles of users effectively.
