A Generic Solution Approach for Integrating Adaptivity into Web-based E-Learning Platforms

Adaptation is a well known concept in the field of e-learning and is increasingly applied in modern learning systems. In order to gain more flexibility and to enhance existing e-learning platforms, we have developed a generic solution approach which enables to add adaptation functionality to existing Web-based e-learning systems. In this paper we present a distributed architecture on the basis of Web services, which is based on experiences gained in the AdeLE and iClass research projects. This flexible solution allows for adapting towards various devices, such as PCs and handhelds. The first running prototype implements the formal Competence-based Knowledge Space Theory for effective assessment of pre-knowledge and knowledge acquisition as well as for determining the sequence of learning content.
