the Learning to Change/Changing to Learn video was made by the talented folk (Stephen Brown et al). With a host of sensible folk intervied this was a provocation for the excellent Consortium for School Networking conference in 2008. It is used by a LOT of schools as a stimulus for CPD, discussion etc. Lots of useful little sound bites, great production values.
