SlideWiki wins the creative innovation project award 2014 for OpenCourseWare excellence

April 27, 2014 - 9:15 pm by AliKhalili - No comments »

Just a couple of days ago, a paper about SlideWiki was presented at OCW Consortium Global Conference 2014 in Ljubljana, Slovenia. The paper was addressing “Crowd-sourcing (semantically) Structured Multilingual Educational Content (CoSMEC)”. In the presentation, Darya Tarasowa gave a detailed overview of the creation of multilingual open educational resources (OERs) in SlideWiki. SlideWiki is an OpenCourseWare authoring platform which enables crowdsourcing of the truly reusable structured open educational content.

At the closing ceremony of the conference, SlideWiki received the creative innovation project award for OpenCourseWare excellence from OCW Consortium. Project awards are aiming to recognize efforts that support the production, use and/or promotion of OCW/OER in ways other than the creation and use of material resources. The Creative Innovation Award recognizes outstanding innovations that bring a new approach to Open Education. Ideas or solutions presented as sites, courses or projects that substantially improve the discoverability, presentation, usability, accessibility or availability of course materials.
