This volume focuses on real-world examples of teacher-researcher collaborations in TESOL in a variety of contexts. The book begins with a review of conceptual foundations and cultural factors that facilitate or hinder TESOL educators’ engagement in and with research. The chapters that follow contain diverse geographic representations, topics, and author voices engaged in research collaborations, illustrating approaches to ethical and cross-cultural challenges of such engagement, as well as successes. The proliferation of a neo-liberal agenda in education that has an impact on local TESOL classrooms has generated a sense of urgency for teacher-researcher collaborations that promote diversity, equity, and inclusion in TESOL, to which this volume responds. The chapters document how a range of TESOL educators including teachers, teacher educators, teacher candidates, and researchers developed and reflected on their collaborations with the aim of building a culture of research in English language education.  This volume will be of high interest to English language and language teachers, graduate/undergraduate students, teacher educators, researchers in areas of TESOL, language education, applied linguistics, literacy education, and teacher education.
