    Este artículo, que será presentado el próximo Mayo en el 5th International Conference on Computer Supported Education (CSEDU2013), propone el concepto de CrowdLearn como un paradigma para explotar el conocimiento, la creatividad y la productividad para la creación de contenido de aprendizaje  rico y semánticamente estructurado. Este concepto combina el estilo wiki para la creación de contenido de colaboración con los requisitos de SCORM para la reutilización.

    Evaluan su aproximación con SlideWiki, una plataforma educacional que sigue el paradigma CrowdLearn.

     

     

    While nowadays there is a plethora of Learning Content Management Systems, the collaborative, communitybased creation of rich e-learning content is still not sufficiently well supported. Few attempts have been made to apply crowd-sourcing and wiki-approaches for the creation of e-learning content. However, the paradigm is only applied to unstructured, textual content and cannot be used in SCORM-compliant systems. To address this issue we developed the CrowdLearn concept to exploit the wisdom, creativity and productivity of the crowd for the creation of rich, deep-semantically structured e-learning content. The CrowdLearn concept combines the wiki style for collaborative content authoring with SCORM requirements for re-usability. Therefore, it enables splitting the learning material into Learning Objects (LOs) with an adjustable level of granularity. In order to realize the CrowdLearn concept, a novel data model called WikiApp is devised. The WikiApp data model is a refinement of the traditional entity-relationship data model with further emphasis on collaborative social activities and structured content authoring. We implement and evaluate the CrowdLearn approach with SlideWiki – an educational platform dealing with presentations and assessment tests. The article also comprises results of a usability evaluation with real students.
