This edited volume brings together a state-of-the-art collection of leading and emergent research on the burgeoning topic of science identities. It sets out how science identity can be productively used as a lens in understanding patterns and inequalities in science participation across different educational and international contexts. Its chapters reveal how intersections of social identities and inequalities shape participation and engagement in science. Particular attention is given to explicating issues of theory and method, identifying the potential and limitations of approaches and lacunae in existing knowledge. The book showcases research from a range of disciplinary areas, employing diverse methodological and conceptual approaches to investigate science identities across different fields and settings. The collection offers a rich and comprehensive understanding of how science identity can be used conceptually, methodologically and analytically to understand how learners andteachers relate to, and make sense of, science. It’s a valuable resource for students, researchers and academics in the field of science education and anyone who is interested in identity and education.
