Dear colleagues, Contributions are being solicited for a special issue of the Journal of Computer Assisted Learning (JCAL) on 'Learning Analytics in Massively Multiuser Virtual Environments and Courses'. The scope of the issue includes both massively multiplayer online games (e.g. World of Warcraft) and virtual worlds (e.g. Second Life) as well as massive open online courses (MOOCs), whether they be 'xMOOCs' delivered via one of the major MOOC platforms (Udacity, Coursera, edX) or connectivist-style 'cMOOCs' offered independently of those platforms. The Call for Papers is available at http://goo.gl/2STf3V . Proposals consisting of 500-word abstracts and 7-10 key references are due on 30 September 2013, and the deadline for submission of full manuscripts is 27 January 2014. Queries regarding the special issue should be directed to jcal.specialissues@gmail.com (but please note that proposals and full manuscripts are not to be sent to this address - see the Call for Papers for submission instructions). Kind regards, Paul A. Kirschner (Open University of the Netherlands), JCAL Editor-in-Chief Liesbeth Kirchner (Open University of the Netherlands), JCAL Associate Editor Mark J. W. Lee (Charles Sturt University), JCAL Editor-in-Charge of Special Issues
