This book provides readers with a range of approaches and tools for thinking deeply about conducting research in their own language classrooms. The book’s accessible style and content encourage language teachers to become part of a community focused on inquiry, equipping them with relevant terminology and concepts for their own teaching and research (inquiry, data collection, data analysis, bringing it all together). The reader is exposed to various research methods and examples, accompanied by pros and cons and rationales for each. This enables them to select which research approaches resonate most and are relevant to their own teaching. The book is designed to empower language teachers to engage in ongoing research, thus democratizing who might be considered a researcher. It includes a range of activities and reflections that can be adapted for both pre- and in-service language teachers in diverse language classrooms.
