Only one session this afternoon -- it was scheduled long and ran even longer. The presenter was John Tagg, an emeritus at Palomar College, and the announced topic was "Framing Change in Higher Education -- Why is it so difficult? How can we make it easier?"Well, doing sustainability work on campus is all about framing change. Or rather, it's about achieving change, and it's hard to do that successfully without framing the change you hope to accomplish. Or maybe the issue you hope to address, even if the outcome has to be left pretty flexible at first.
