This volume introduces the histories and traditions that have inspired innovation in thinking and writing about policy making and policy worlds in the field of education. Through a focus on post-positivist epistemologies and anti-foundationalist philosophies, this volume documents some of the most recent theoretical and empirical developments in the education sub-field of 'policy sociology', also known as 'sociology of education policy' or 'critical policy sociology'. The result is a comprehensive text and navigational tool for studying the application and merit of poststructuralist and social constructivist approaches to education policy scholarship. About the Educational Foundations series: Education, as an academic field taught at universities around the world, emerged from a range of older foundational disciplines. The Educational Foundations series comprises six volumes, each covering one of the foundational disciplines of philosophy, history, sociology, policy studies, economics and law. This is the first reference work to provide an authoritative and up-to-date account of all six disciplines, showing how each field's ideas, methods, theories and approaches can contribute to research and practice in education today. The six volumes cover the same set of key topics within education, which also form the chapter titles: - Mapping the Field - Purposes of Education- Curriculum - Schools and Education Systems - Learning and Human Development - Teaching and Teacher Education - Assessment and Evaluation This structure allows readers to study the volumes in isolation, by discipline, or laterally, by topic, and facilitates a comparative, thematic reading of chapters across the volumes. Throughout the series, attention is paid to how the disciplines comprising the educational foundations speak to social justice concerns such as gender and racial equality.
