The World Wide Web has become a widely available platform for learning with hypermedia. However, WWW hypermedia is often limited in both guidance and navigation support. To improve hypermedia in these aspects, we propose a spatial hypermedia browser for educational purposes. A prototype browser, named HyperMap, has been designed to integrate guided explorative browsing with external control ove...

In this paper an instructional framework is proposed for supporting personalised learning in the context of webbased adaptive educational hypermedia systems. A learning-focused approach of instruction is adopted aiming to address learners’ needs and accommodate their learning style preferences and progress during interaction. In particular, the proposed framework unifies several processes that ...

abstract Adaptive Hypermedia (AH) can be considered the solution to the problems arising from the " one-size-fits-all " approach to information delivery prevalent throughout the WWW today. Adaptive Educational Hypermedia (AEH) aims to deliver educational content appropriate to each learner, adapted to his or her preference and educational background. The development of AEH authoring tools has l...

Adaptive navigation support (ANS) is a new direction of research within the area of adaptive interfaces. The goal of ANS techniques is to help users find an appropriate path in the learning and information space by adapting link presentation to the goals, knowledge, and other characteristics of an individual user. This paper is devoted to evaluation of adaptive navigation support in educational...

AHA! is an Open Source adaptive hypermedia platform, resulting from 10 years of experience with creating, using and improving on-line adaptive courses and presentations. This paper focuses on some recent additions to AHA! that are especially important for adaptive educational applications, namely stable presentations, adaptive link (icon) annotations and adaptive link destinations. We not only ...

In the past decade, a number of adaptive hypermedia learning systems have been developed. However, most of the systems tailored presentation content and navigational support basing on prior knowledge or cognitive styles of students separately. There is a need to, however, explore how the two individual difference characteristics could be combined in adaptive hypermedia learning systems in order...

This paper discusses Adaptive Educational Hypermedia (AEH), which is at present a hot topic of research and an important aim for commercial educational systems. Section 2 considers generally current AEH advances and summarises main directions of research. Section 3 presents a project where an adaptive Computer-Aided Language Learning (CALL) environment was developed. Section 4 focuses on studen...

The large variety of user-adaptive educational hypermedia systems available requires techniques for evaluation and comparison with other adaptive systems. In this paper the current evaluation approaches used for assessing intelligent e-learning environments are presented. The paper discusses important issues emerging from research on system evaluation that focuses on both social and practical a...
