In this volume teachers describe their struggle to understand constructivism, and to transform their mathematics instruction. The book also contains essays, by teacher educators, exploring new challenges posed by the new mathematics pedagogy for the multiple identities teachers are asked to enact.

This volume presents narratives written by teachers working with constructivist methods to transform their mathematics instruction, and includes essays by teacher educators. The aim of the book is to consider what is involved when teachers work to realise reform principles in day-to-day practice.

These teacher narratives explore some challenges posed by the new mathematics pedagogy for the multiple identities teachers are being asked to enact professionally: as mathematical thinkers, acquiring the needed understandings of mathematics content and modes of thought; as managers of classroom process, and much more.
