The UK Teaching and Learning Research Programme (TLRP) worked for ten years to improve outcomes for learners in schools and other sectors through high quality research. One outcome of individual projects and across-Programme thematic work was the development of ten ‘evidence-informed’ principles for effective pedagogy. Synopses of these principles have been widely disseminated, particularly to practitioners. However, the evidence and reasoning underpinning them has not yet been fully explained. This book fills this gap by providing a scholarly account of the research evidence that informed the development of these principles, as well as offering some evidence of early take-up and impact. It also includes responses from highly-respected researchers throughout the world in order to locate the work in the broader international literature, to extend it by drawing on similar work elsewhere, to provide critique and to stimulate further development and debate. Principles for Effective Pedagogy contributes to international dialogue on effective teaching and learning, providing a focus for scholarly comment, sharing of expertise and knowledge accumulation. This book was originally published as a special issue of Research Papers in Education.
