Schools are filled with great teachers, but is great teaching taking place in every classroom, in every school? Bruce Robertson doesnt believe it is. Why not? This book argues that there are two reasons. Firstly, because there isnt a shared understanding of what makes great teaching. Secondly, because schools havent developed the strong professional learning culture necessary to drive the development of great teaching in every classroom. Through discussion of key messages from educational research, and drawing on a track record of success, this book explores how these barriers can be addressed, leading to transformations in teaching practice across classrooms and schools.
