In Search of Reusable Educational Reso...

Nowadays there is a high demand from teachers to precisely find online learning resources that are free from copyright restrictions or publicly licensed to use, adapt and redistribute in their own courses. This paper investigates the state of the art to support teachers in this search process. Repository based strategies for dissemination of educational resources are discussed and critiqued and the added value of a semantic web approach is shown. The ontology schema.org and its suitability for semantic annotation of educational resources is introduced. Current ways and weaknesses to discover educational resources based on appropriate semantic data are presented. The possibility to use the wisdom of the crowd of learners and teachers defining semantic knowledge about used learning resources is addressed. For demonstration purposes within all sections the course subject ‘Semantic SEO’, dealt in the course ‘SEO – Search Engine Optimization’ held by the author in 2016, is used.
