This book explores the contexts for gender identity development in early childhood education, examining how early childhood educators’ views on children’s gender identity influence their practice in Australia. The author utilizes feminist post-structuralism, queer theory and performativity as theoretical approaches, and feminist post-structuralist discourse and thematic analyses. The book captures the voices of educators and developers of curriculum documents to explore how gender expansive environments can be created when such environments are socially and politically contentious. It then identifies discourses that enable and constrain the building of pro-diversity spaces and contexts in early childhood education, while considering how to disrupt normative notions of gender and promote the deployment of discursive agency.
