Introduces alternative models of mathematical learning that improve on simple hierarchical models *Develops understanding of how mathematical pedagogy has changed post-Vygostky and Piaget *Foreward by Jerome Bruner

How and why is mathematics taught? These can be problematic questions. The book seeks to improve on our current answers, finding better and more truthful explanations which are backed by evidence. The contributors have diverse perspectives, but their chapters are richly cross-referenced and commented on, to create a stimulating discourse. Agreement is found on particular matters, such as the need for non-hierarchical approaches, and the contributions are all well written to be relevant to policy-makers and practitioners, as well as researchers.
