The aim of this book is to bring teacher research to the centre of attention in educational research. Knowledge generated by researching teachers and teacher researchers - often in collaboration with university researchers - identifying new and innovative research methodologies and theories, feeds directly back into theorising practice and the practice of theory that is necessary to improve student learning. This edited volume is unique in that it details diverse teacher research practices and partnerships across a diversity of cultural settings (from Sweden, Turkey, South Africa, Cyprus, Singapore, Hong Kong/China, Australia and the UK). In this volume, 19 internationally acknowledged researchers from nine different countries draw on and develop a new wave of theory and practice for transformative teaching and learning. Themes explored include: contributions of the latest emerging theories and research approaches, types/models of university-school partnerships and teacher research communities which build, change and sustain educational reform, empirical findings and evidence-based benefits from teacher research and professional learning, critical policy research in teacher research, innovative approaches to course designs with an aim to transform understanding of teaching and teacher research.
