On-line learning resources attract great interest from governments and educational institutions as they may be shared and reused, thus lowering production costs and fostering knowledge interchange among teachers and learners. These resources known as Open Educational Resources (OERs) include a wide variety of educational materials, among which are OpenCourseWare (OCW). The sustainable development of the education sector can be achieved by having available, accessible, multilingual, and high-quality OCW. However, currently there is a lack of educational content with these key features due to the fact that their creation and maintenance is tedious, time-consuming and expensive. One way of alleviating the labor-intensive work of creating and maintaining learning materials is by using a collaborative authoring platform such as the open-source SlideWiki platform 2.0 ( that allows users to create and maintain OCW (e.g. slide presentations and self-assessment tests) in a crowdsourcing and on-line fashion. In general, collaborative authoring has improved the efficiency, effectiveness, quality and timeliness of content creation; this has been proven in different domains such as text and software code. Therefore it is expected that in the educational domain, a crowdsourcing approach helps to increase the quantity and quality of OCW. Learning materials can be reused in two different ways: (1) learning materials used for different educational events and (2) learning materials used as components during the authoring process. This second perspective helps to reduce the production cost of new high-quality OCW with particular features such as accessibility and multilingualism. However, there is currently no systematic approach to reuse learning resources as ingredients in the educational content creation process. In this paper we present a novel approach for the creation of learning materials that is based on reusing educational content that may be presented in different languages, and on the crowdsourcing concept. The proposed approach uses the collaborative SlideWiki 2.0 authoring platform and is applied to a particular use case for the production of learning materials in the Semantic Web domain. The educational materials produced are used in undergraduate, graduate and open community courses and are enriched by groups of authors and course participants.
