This book explores and builds on the extraordinary work of Professor Paul Black across assessment and pedagogy across the curriculum, including STEM, humanities and social science subjects. This book explores the influence that Black has had within educational settings focusing on interpretations of the work and scholarship he has achieved across a range of settings and on the ways scholars, who have worked with him or been influenced by his ideas, have developed their research and teaching. The contributions are presented under three thematic sections, each of which reflects a set of shared educational concerns and values drawing on the natural and social sciences and developments in public policy. These concerns and values, with their emphasis on teacher assessment, provide a basis for a strategic, informed and coherent response to challenges in education, such as the cancellation of public examinations in the face of the Covid-19 pandemic.
