European conference on Technology Enhanced Learning that took place in Graz, 16-19 September 2014. (The actual proceedings are in a priced publication from Springer Verlag).
The interviews are at http://openeducationeuropa.eu/en/node/161897 which is part of the Open Education Europa website (worth exploring: lots of project and course listings and resources).
I picked up on this because of the interview with Rebecca Ferguson and Mike Sharples, who are talking about pedagogy in MOOCs (their powerpoint is here: http://www.slideshare.net/sharplem/innovative-pedagogy-at-scale-ectel): there is also a video summary of the whole MOOCs session and another video is on wearable learning. Following a link, I also found a site on Social Mobile Learning http://www.somolearn.org/home which you might find interesting if you are designing learning using mobile/social media.
