From Learning Objects to Adaptive Content Services for E-Learning

Abstract

This paper argues that a new generation of powerful E-learning systems could start on the crossroads of two emerging fields: courseware re-use and adaptive educational systems. We argue for a new distributed architecture for E-learning systems based on the idea of adaptive reusable content services. This paper discusses problems that have to be solved on the way to the new organization of E-learning and reviews existing approaches and tools that are paving the way to next generation E-learning systems. It also presents two pioneer systems - APeLS and KnowledgeTree that have attempted to develop a new service-based architecture for adaptive E-learning.
