Adaptive Educational Hypermedia aims to provide tailored and personalised learning experiences to different students. However, one of its limitations which have resulted in its poor adoption by the e-learning community is the complexity of its authoring process. This paper tries to address this issue in order to push those adaptive systems forward. First, it presents an authoring aid for an exi...

AHA! stands for the Adaptive Hypermedia Architecture, an adaptive authoring and delivery platform developed as part of the Adaptive Hypermedia for All (or AHA!) project. (See http://aha.win.tue.nl/.) Adaptation in on-line textbooks makes it possible for learners to study the textbook in different ways without encountering difficulties. Link hiding and annotation guide users towards subjects the...

Adaptive learning is an educational method which uses computers as interactive teaching devices. Computers adapt the presentation of educational material according to students' weaknesses, as indicated by their responses to questions. The motivation is to allow electronic education to incorporate the value of the interactivity afforded to a student by an actual human teacher or tutor. The techn...

Students benefit from personalised attention; however, often teachers are unable to provide this. An Adaptive Hypermedia (AH) system can offer a richer learning experience in an educational environment, by giving personalised attention to students. On-line courses are becoming increasingly popular by means of Learning Management Systems (LSM). The aim of the GRAPPLE project is to integrate an A...

Personalized recommenders have proved to be of use as a solution to reduce the information overload ‎problem. Especially in Adaptive Hypermedia System, a recommender is the main module that delivers ‎suitable learning objects to learners. Recommenders suffer from the cold-start and the sparsity problems. ‎Furthermore, obtaining learner’s preferences is cumbersome. Most studies have only focused...

This paper discusses problems concerning the design of educational applications in general, as well as specific problems connected with educational applications meant to be published on the Web. A new approach to the authoring and maintaining of Web-based educational applications is proposed which is based on the concept of hypermedia composites. Hypermedia composites can be seen as a higher le...

An essential factor for usable and expedient operation of web-based educational systems is incorporation of pedagogical principles. However, the extent of incorporating pedagogical principles in recently developed e-learning systems is not broad enough. The purpose of this paper is to illustrate the present development and future capabilities of a new, pedagogically based, AHES (Adaptive Hyperm...

Spatial hypermedia provides opportunities for expression not possible in navigational hypertext. However, static spatial hypermedia, just like static traditional hypermedia, has a single presentation for all use contexts. We are exploring the use of multiple adaptation models to alter the presentation of spatial hypertext. Differences between navigational and spatial hypertext expression requir...
