Arguing that all teachers are necessarily language teachers needing to traverse increasingly diverse educational settings, this book focuses on how language impacts learning in every subject, helping teachers of all disciplines to fully realise the skills and knowledge needed to teach inclusively. Featuring the voices of novice and expert teachers and teacher educators across a range of disciplines and contexts, the volume demonstrates the importance of social skills such as empathy, cultural awareness and open mindedness within these diverse educational settings. Chapters combine international perspectives with practical strategies and real-world case studies, as well as reflection points and opportunities for action planning; specifically designed ‘language challenges’, aimed at inspiring teachers to develop language curious classrooms, are interwoven through the book. Ultimately, the volume is designed to help recognise and unlock the full linguistic repertoire of teachers, students and mentors in order to develop high-quality and inclusive pedagogies that target linguistic and emotional barriers to closing existing attainment gaps.
