Development of a system that provides teachers with useful resources from various viewpoints based on ontology

In Japan, teaching of the subject "Information" was started in the high schools in April 2003, and interest in IT/information education has continued to grow since then. It is very difficult to design IT/information education materials, and there are very few specialist teachers of IT/information education. For this reason, it is necessary and important to provide teachers of IT/information education with a variety of useful resources. To that end, we are building a system that supports teachers in designing instructional materials for IT/information education. Here, we describe a part of this system that reconstructs resources according to the various viewpoints which teachers require. This function of the system is realized by tagging each resource with the ontology of IT/information education in the Resource Description Framework (RDF).
