Seeking open educational resources to compose massive open online courses in engineering education an approach based on linked open data

Abstract

The OER movement has tended to define �openness� in terms of access to use and reuse educational materials, and to address the geographical and financial barriers among students, teachers and self-learners with open access to high quality digital educational resources. MOOCs are the continuation of this trend of openness, innovation, and use of technology to provide learning opportunities for large numbers of learners. In the last years, the amount of Open Educational Resources on the Web has increased dramatically, especially thanks to initiatives like OpenCourseWare and other Open Educational Resources movements. The potential of this vast amount of resources is enormous. In this paper an architecture based on Semantic Web technologies and the Linked Data guidelines to support the inclusion of open materials in massive online courses is presented. Linked Data is considered as one of the most effective alternatives for creating global shared information spaces, it has become an interesting approach for discovering and enriching open educational resources data, as well as achieving semantic interoperability and re-use between multiple Open Educational Resources repositories. The notion of Linked Data refers to a set of best practices for publishing, sharing and interconnecting data in RDF format. Educational repositories managers are, in fact, realizing the potential of using Linked Data for describing, discovering, linking and publishing educational data on the Web. This work shows a data architecture based on semantic web technologies that support the inclusion of open educational materials in massive online courses in engineering education. The authors focus on a type of openness: open of contents as regards alteration i.e. freedom to reuse the material, to combine it with other materials, to adapt and to share it further under an open license.
