The Association of Learning Technologists Conference (ALT-C) is in Leeds in 2008, and they are now welcoming submissions of either research papers for publication in the peer-reviewed proceedings or abstracts for demonstrations, posters, short papers, symposia and workshops. The deadline for submissions is 29 February 2008.
ALT-C covers pretty much everything that you might call Learning Technology, and if you are using new technologies in teaching and learning there is a good chance you'll meet other people there who are doing something similar. I found it a good place to talk with people and consolidate ideas I'd been thinking about - but to do that you need to avoid spending all 3 days in sessions, or you'll just arrive back at work with a head full of ideas and no time to sort out what they mean to your future work!
To read of people's experiences at ALT-C visit Technorati, or read my posts from 2007 in Nottingham (day 1, day 2, day 3, after), and have a think if you've got anything to present there.
