A great post by Ian Jukes. The writing is certainly on the wall for the "bring in the expert and sit up straight" style of professional development. I've been wondering for years why schools don't pool their collective expertise to create a culture of learning in their schools. Some of the "experts" that are brought in don't even have the practical or even theoretical expertise of residing staff members. This year a visiting professional told me, "When it comes to schools, there are never any prophets in your own backyard." The zeitgeist is certainly suggesting we need a change.
