Towards a semantic learning model fostering learning object reusability
Abstract
We try in this paper to propose a domain model for both author's and learner's needs concerning learning objects reuse. First of all, we present four key criteria for an efficient authoring tool: adaptive level of granularity, flexibility, integration and interoperability. Secondly, we introduce and describe our six-level Semantic Learning Model (SLM) designed to facilitate multi-level reuse of learning materials and search by defining a multi-layer model for metadata. Finally, after mapping different learning content models with our SLM, we show how our Phoenix authoring tool can deal efficiently with share-and-reuse problem.
