This gives a clear context and rationale for the 3 phase model introduced within the book. This is a valuable textbook.
This book is a 'must read' for all those interested in mathematics pedagogy.
This book, and the videos available on the internet, provide the best aggregation of educational research that I have ever seen. The information provided is up to date, and draws on the work theorist such as Dweck and Boaler. The book covers all grades (year groups), and includes a sample of useful vignettes.
