This year, the European Conference on Technology-Enhanced Learning will be held in Lyon, France, from the 13th to 16th September. The conference currently has a call for papers out on a wide range of topics around the technology and pedagogies in relation to technology-enhanced learning, and their relationship with the formal institution (the 'schools and universities of the future' topic made me think of HASTAC!).
The call for papers has a deadline of 14th March for abstracts, quickly followed by full paper submission by 29th March. The conference also hosts a doctoral consortium, which has a longer deadline for submissions (29th May).
