Adaptive Educational Hypermedia Systems

Definition:Adaptive educational hypermedia systems include adaptive functionality based on three components: the document space, observations, and the user model.

To support re-usability and comparability of adaptive educational hypermedia systems, we give a component-based definition of adaptive educational hypermedia systems (AEHS), extending the functionality-oriented definition of adaptive hypermedia given by Brusilovsky in 1996 [1]. AEHS have been developed and tested in various disciplines and have proven their usefulness for improved and goal-oriented learning and teaching. However, these systems normally come along as stand-alone systems — proprietary solutions have been investigated, tested and improved to fulfill specific, often domain-dependent requirements. This phenomenon is known in the literature as the open corpus problem in AEHS [2]which states that normally, adaptive applications work on a fixed set of documents which is defined at the design time of the system, and...
