Designing and Automatically Generating Educational Adaptive Hypermedia Applications

Educational Adaptive Hypermedia Applications (EAHA) provide personalized views on the learning content to individual learners. They also offer adaptive sequencing (navigation) over the learning content based on rules that stem from the user model requirements and the instructional strategies. EAHA are gaining the focus of the research community as a means of alleviating a number of user problems related to hypermedia. However, the difficulty and complexity of developing such applications and systems have been identified as possible reasons for the low diffusion of Adaptive Hypermedia in web-based education. Experience from traditional Software Engineering as well as Hypermedia Engineering suggests that a model-driven design approach is appropriate for developing applications where such requirements and constraints occur. This paper presents on a model-driven design process of EAHA. This process accords to the principles of hypermedia engineering and its innovation is the use of a formally specified object oriented design model.
