In a learning institution such as a school, we face many changes as we learn more about teaching and learning, as we gain insight about the genius each of our students brings to our community, and as we collaborate to find adaptive solutions to our puzzles of practice. In this post, I want to describe a model we have used in my school district to reflect on change and strive to support teachers as we engage in change processes. This model, developed by Hendrik Knoster, is called the Knoster Model.
