CoLearn: Real time collaborative learning environmentCoLearn: Real time collaborative learning environment Πλήρης Δημοσίευση σε Συνέδριο Conference Full Paper 2015-10-032013enComputer Supported Collaborative Learning hasbecome an important part of e-learning providing interactivityand accessibility to learning resources either synchronouslyor asynchronously among users. In order to develop an elearning environment that supports collaborative learningone should cope with learning content, communication andcollaboration facilities, technological infrastructure, and runtime execution (i.e. learning process). Collaboration scripts areemployed to specify the components of the learning processincluding collaboration and interaction patterns within groupsof participants. In this paper we present a Computer SupportedCollaborative Learning platform which includes a collaborationscript authoring tool based on the Business Process ModelingNotation as the model for the graphical representation of scripts.Collaboration scripts are parsed and transformed to IMSLearning Design Level C learning flows. The second importantcomponent of the platform is the run time environment whichis based on the Copper Core Engine that executes the IMSLearning Design learning flows and a Message OrientedMiddleware which is built over the Extensible Messagingand Presence Protocol. This middleware layer enables groupmanagement and social interaction among participants. Theplatform integrates external learning tools by implementingthe IMS Learning Tool Interoperability specification. The IMSLearning Tool Interoperability specification is used to enable thedynamic integration of external tools through services.http://creativecommons.org/licenses/by/4.0/13 - 18The Second International Conference on E-Learning and E-Technologies in Education (ICEEE2013), Sept. 23-25 Poland 2013 Christodoulakis Stavros Χριστοδουλακης Σταυρος Nektarios Moumoutzis Polyxeni Arapi George Stylianakis Institute of Electrical and Electronics Engineers
