From this recent MindShift article on ways leaders can support meaningful innovation in schools:
When schools try to innovate, they often take a traditional top-down approach: devise a strategy, roll it out to teachers and support a high-fidelity implementation. The end result is often one that lacks teacher support or genuine enthusiasm — initiatives putter along and change is sporadic or modest.
In education and beyond, innovation is usually the result of iteration rather than central planning. In schools that succeed in implementing real instructional improvements, teachers figure out how to improve teaching and learning by journeying through multiple passes of a cycle of experiment, reflection and adjustment.
Again, if you want to take the greatness out an innovation, make everyone do it. Let it bubble up from the classroom so that it becomes the norm rather than the exception.
