This anthology of papers is a great foundation of pieces for anyone considering coaching in K-12 schools or who wants to know more about the function of coaching in a professional development plan. It looks at coaching in broad strokes, but provides enough examples and details to grab onto if you want to go deeper. The references alone in each chapter offer an abundance of options in a learning buffet! One could dip in and out for ages.
I particularly enjoyed the chapters on Content Coaching (not what I expected!) and Differentiated Coaching (totally aligned with my goals this year). I had already immersed myself in the content of the Coaches' Roles chapter, as I'm a huge Joellen Killion fan and have been using her work for nearly 10 years now. I also already live in the world of Cognitive Coaching, so this chapter also wasn't so relevant to me. I kind of breezed through the last chapter, on research, as I felt it was a bit out of date already. Its generalizatons, though, are still valid and affirming.
