Using RDF/RDFS to support visualized online authoring tool for teachers

The purpose of this study is to implement visualized online authoring tool (VOAT) by using RDF/RDFS for teachers at primary and junior high school levels in Taiwan to author their teaching materials. Based on the content repository management system (CRMS), this study addresses the interoperability problem consequence of the proliferation of online learning systems, mainly in Internet environments, which is considered by key standardization institutions such as ADL´s SCORM specifications. Using mathematics ontologies by RDF/RDFS in this study gives teachers a more intuitive choice of mathematics of the modeling primitives and richer ways to define mathematics concepts and attributes. RDF/RDFS introduces basic ontological modeling primitives into the Web. The result of this study is demostrated by a scenario that selected to explain how teachers authoring a mathematics course on VOAT. Finally, the implications for future research are also proposed.
