Abstract

Adaptive navigation support can be of great help in large hypermedia systems supporting learners as well as users searching for specific information. A wide variety of adaptive mechanisms have been implemented in existing adaptive hypermedia systems that provide better and better suggestions to the user what hyperlinks to follow. We suggest that adaptive navigation support should scaffold a learner in an educational hypermedia system to select the appropriate links. We show that this implies that selecting a link is an educationally relevant activity that should not always be reduced to a trivial task by powerful adaptive mechanisms. It follows that learners require sometimes different kinds of adaptive navigation support than users looking for information. Finally, we will suggest how to extend current mechanisms to provide scaffolded navigation support to learners.
