This book is for any educator who's interested in understanding how learning works, and how to optimise their teaching to make it happen. From the author of Lean Lesson Planning, this latest instalment in the High Impact Teaching series pulls together the best available evidence from cognitive science and educational research, and stitches them together into a concise and coherent set of actionable principles that can be used to improve your impact in the classroom. It's an evidence-informed teacher's guide to building enduring understanding, and sits alongside books such as Make It Stick, Why Don't Students Like School?, and What Every Teacher Needs To Know About Psychology.
