Conducted by Denise Pilar da Silva, Rafaël Van Durm, Erik Duval, Henk Olivié of Katholieke Universiteit Leuven, Belgium. Similar to the Aristotle University study, a prototype adaptive hypermedia system was created. This particular system uses three frames within the single browser window to display the navigation tree, relevant content links, and the content itself. It also utilized a link hiding feature to remove links to content already viewed, however, this was ultimately received as confusing.
Some important conclusions from this study include redesigning navigation trees to show more localized navigation and less overall hierarchy in order to reduce cognitive overhead. Additionally they concluded it is worthwhile to redesign the measures of difficulty and concept coverage so that it is in direct relation to a user's knowledge model. However, the main problem encountered is how to properly define relationships between documents and difficulty ratings and thresholds in proper relation to the user and content. Also importantly, it is noted that proper knowledge of the content in the course is important when deciding relationships between content. In other words, designing an adaptive educational course might be best done on an individual basis rather than creating an all encompassing format for all courses of varying areas of focus.
