Ontology-Based Learning Activity Sequencing in Personalized Education System

E-learning has a various established approaches to the creation and sequencing of content-based, single learner, and self-paced learning objects. However, there is little understanding of how to create sequences of learning activities which involve groups of learners interacting within a structured set of collaborative environments. This paper describes an approach of learning activity sequencing based on ontology and activity graph. Modeling and management of learning activity and learner were depicted, and an algorithm is proposed to realize activity sequencing and learner ontology dynamically updating.
