This document discusses implementing change in organizations and the challenges that come with it. It outlines the different stages of concern educators have when new practices are introduced, from initial non-use due to lack of knowledge to mastery of new strategies through reflection. It also describes five types of adopters - from innovators who try new ideas quickly to resistors who are isolated and resistant to change. The change process is not linear and will face problems that leaders must address through collaborative professional development to maintain enthusiasm and momentum for change.
