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 problem...

This paper addresses two questions related to educational multimedia applications: • What lessons should we learn from today's Graphical User Interfaces (GUIs)?, and • What the user interfaces should look like in the future? We address the first question by drawing on our experience from two multimedia projects, that deal with multimedia proceedings and multimedia lectures. For the second quest...

LSA, a mathematical modeling technique, captures the essential relationships between text documents and word meaning, or semantics, the knowledge base which must be accessed to evaluate the quality of content. Several educational applications that employ LSA have been developed: (1) selecting the most appropriate text for learners with variable levels of background knowledge, (2) automatically ...

Intelligent tutoring systems (ITS) acquire rich data about students’ behavior during learning; data mining techniques can help to describe, interpret and predict student behavior, and to evaluate progress in relation to learning outcomes. We describe applications of data mining to challenges related to finding patterns in student actions at the level of single problems to predictions across ses...
