Towards a global architecture for learning objects: a comparative analysis of learning object content models

Abstract

This paper investigates basic research issues that need to be addressed in order to reuse learning objects in a flexible way. We review a number of learning object content models that define learning objects and their components in a more or less precise way. A comparative analysis is made of these models in order to address questions about repurposing learning objects in a different context. The content models are mapped on our general model for learning objects to facilitate the comparison. 1.
