Early in this volume Chris Day writes: "We now live in a climate in which many teachers struggle to teach to their best and well." For me, the book is a deeply committed investigation of why this is and how teachers in the contemporary world, both through their own determination and through the creation of the right conditions in their schools and classrooms, can challenge this climate. The vision is both realistic and humane, drawing as Day does, on a wide range of research, both his own and that of many other scholars. His great achievement is to join together many different perspectives in order to integrate the insights into a holistic portrayal of what it may mean to be a successful teacher in the twenty-first century. Ian Menter, Emeritus Professor of Teacher Education, University of Oxford, UK Almost no-one, worldwide, comes close to having the mastery of research on teachers'' work and teachers'' professional learning and development, that is possessed by Chris Day. In this magnum opus of a text, Professor Day brings together decades of understanding and insight into the core elements of teaching quality such as teachers'' commitment, teacher resilience and teachers'' identity. Day''s work is erudite, accessible and entirely up-to-date, but most of all, it is deeply appreciative of who teachers are, what teachers do and why they do it. Andy Hargreaves, Brennan Chair in Education, Boston College, USA This book makes a significant contribution to understanding the complexities of the work and worlds of teachers.

It brings together the work, insights and contributions Chris Day has made to the field of education in general and the teaching profession in particular over a long and sustained career. Teachers worlds and work helps us to make sense of how the complexities of teaching and being a teacher are connected to influence the design, development and enactment of government and school policies, strategies, and cultures. Day''s voice as an advocate for teachers and the teaching profession is strong and confident and, with a political intent and an optimistic vision, it provides a voice for all teachers who are concerned with what really matters for the teaching profession and what needs to matter to all those who are concerned with enhancing their work and effectiveness in times of uncertainty, unrelenting change and policy ambiguity.
