This book is about the reflective journey of Sharada Gade, a teacher-practitioner who turned into a researcher-practitioner. The book holds many lessons, as the author talks about her collaboration with teachers and her experience in coauthoring research reports with them. She also discusses how to teach and implement instructional interventions. This practical knowledge is supported by perspectives from cultural historical activity theory (CHAT). Such a stance offers conceptual clarity to the book's lessons by drawing from across continents, institutions and academic fields. The culmination of these efforts makes for fascinating reading, one that sheds much needed theoretical-practical light for practitioners to take transformative action in their own classrooms.
