Web-based Intelligent Design and Tutoring System (WINDS) is a European project with the objective to implement a learning environment integrating an intelligent tutoring system, a computer instruction management system and a set of cooperative tools. This environment will be used to build a large knowledge base supporting Architecture and Civil Engineering Design Courses and to experiment a com...

Studies (for instance, [1, 2]) show that there is a statistically relevant gender difference in computer usage. In this paper we address the question of what are the causes of this problem and how it can be relieved by adaptive means. In trying to design systems that are sensitive to individual differences there is a dilemma – how can you make the system behave in a way appropriate for each ind...

Adaptive Hypermedia Systems adjust the content to best suit users’ personal characteristics, but rarely consider delivery performance. Performance issues are even more significant in distributed architectures such as that of an Open Corpus Adaptive Educational Hypermedia System (OAEHS). This paper introduces a Performance Oriented Adaptation Agent (POAA) that enhances OAEHS by taking into consi...

This paper addresses the problem of user modeling, which is a crucial step in the development of Adaptive Hypermedia systems. In particular, we focus on adaptive educational hypermedia systems, where the users are learners. Learners are modeled in the form of categories that are extracted from empirical data, represented by responses to questionnaires, via a competitive neural network. The key ...

Interactive open hypermedia systems can be used for medical education. To fit the needs of different types of learners, the systems have to provide an individual educational environment. This paper describes the approach to user adaptive configuration and design of educational scenarios realized in our " MediCAL " system.

A key decision in designing authoring tools for Adaptive Hypermedia is the type of representation to use when authoring the relationships among contents. This paper describes an experiment that compares two representations, one based on trees, another using clustered graphs for the same task. An effort has been made to isolate all other aspects of authoring from the comparison; the choice of tr...

The aim of this paper is to define new structures to promote adaptivity in the existing engineering approaches, concerning specifications and standards for reusable learning design. It is not our intention that the proposed structures be exhaustive, more that they add enough richness to current learning modelling languages in order to support adaptivity in instructional and pedagogical level. I...

In this paper, we present technologies and techniques used in web-based intelligent educational systems (WBIESs). As WBIESs we consider either web-based intelligent tutoring systems (ITSs) or adaptive hypermedia education systems (AHESs) incorporating intelligent techniques. We present technologies and techniques for all the three basic components of a WBIES: the domain knowledge, the student m...

A concern, however, with the educational use of hypermedia is that of user navigation. The issue is how, on the one hand, to prevent the user from becoming overwhelmed with information and losing track of where they are going, while on the other hand permitting them to make the most of the facilities the hypermedia offers. One approach to remedy this is to restrict the number of links made avai...
