Abstract:

A major obstacle to increasing the efficiency, effectiveness and quality of education is the lack of widely available, accessible, multilingual, timely, engaging and high-quality educational material, i.e. OpenCourseWare (OCW). The creation of comprehensive OCW is often a tedious, time-consuming and expensive process, with the effect that courseware employed by educators and trainers can be incomplete and outdated, as well as inaccessible to those with disabilities.

With the open-source and open-access SlideWiki platform, the effort of creation, translation and evolution of highly-structured remixable OCW can be widely shared. Similarly to Wikipedia for encyclopaedic content, SlideWiki allows to collaboratively create comprehensive OCW (curricula, slide presentations, self-assessment tests, illustrations etc.) online in a crowdsourcing manner. SlideWiki has won the OpenCourseWare Consortium’s Excellence Award and is used by hundreds of educators and thousands of learners. Several hundred comprehensive course materials are available on SlideWiki in different languages.

The SlideWiki large-scale trial project is further maturing the SlideWiki platform by improving its usability and accessibility. The SlideWiki project is performing a wide range of trials covering different levels of education (i.e. from secondary to higher education) and different types of learning (i.e. formal learning, informal learning, vocational learning). Each of these large-scale trials is carried out with hundreds of educators and thousands of learners in different countries across Europe. A particular focus of the technology development and testing in the trials is the suitability for academics, teachers and learners with disabilities.

This paper will present the lessons learned from piloting the SlideWiki platform in different learning contexts and scenarios. In particular, we will describe the learning scenarios considered in each pilot and how these scenarios have been implemented with the use of SlideWiki. We will then describe the methodology followed in each pilot, in terms of the authoring, teaching and learning activities performed by educators and learners using SlideWiki. Finally, the lessons learned from each pilot will be discussed, focusing on the challenges faced in each pilot, how these challenges have been addressed, as well as the best practices that have emerged from the pilots regarding the collaborative authoring and sharing of OCW.
