Leadership and Professional Development in Science Education provides invaluable insight into the role of science teachers as learners and thinkers of change processes. The fourteen chapters, by an eminent international team of science educators, explain and explore the relationship between professional development, teacher leadership and teacher learning. Research-based practical and theoretical exemplars reflect state of the art science teacher leadership in a broad range of international contexts. The book is divided into three parts, reflecting a multi-layered approach to teacher learning: * Personal initiatives in teacher learning, focusing on individual teachers; * Collegial initiatives in teacher learning, focusing on groups of teachers; * Systemic initiatives for teacher learning, focusing on system-wide issues. Student teachers and practising teachers will find the text highly valuable as they consider and review the challenges of teaching practice and ways of working with colleagues, while school leaders and policymakers will benefit from the book's insight into system-wide issues of professional development.
