This edited collection explores the use of Exploratory Practice (EP) by language teachers in classrooms. Written by practitioners, the chapters showcase unique examples of each principle of EP, with topics ranging from mentoring practitioner researchers, to teaching and learning in EAP, and investigating curriculum development in language teaching programs. The book provides example EP studies and gives voice to practitioners’ experiences of the challenges they experienced as well as the benefits. Examples include tackling intercultural communication in linguistically and culturally diverse classrooms; pedagogy and curriculum design in language teaching; explorations of continuing professional development in language education. In doing so, it offers tools that can be transferred to other classroom contexts and used to aid teacher development. The concluding chapter highlights critical aspects of Exploratory Practice which emerge in the studies and examines how practitioners advanced their understandings. This book will appeal to those working in Applied Linguistics, TESOL research, as well as language teachers and teacher educators.
