I gave this presentation at 'OERs and Languages' an HEA/OER seminar held at UCLAN, on 1st June, 2012. I talked about how LLAS community OER projects have led to an understanding of how engaging with open practice can lead to professional development in explicit ways (through impact of work on an external audience) and more subtle ways (through reflection, collaboration and review).
