This book is a comprehensive guide to an effective Science Education Fellowship (SEF) program. Spanning more than ten years and involving hundreds of teachers, District Science Coordinators, and university faculty, the Wipro SEF program has empowered teachers to become leaders who drive meaningful, sustainable change in their schools and districts without leaving the classroom. Offering an in-depth look at the SEF program's structure, from its foundation in teacher leadership development to its innovative adaptations across seven universities and 35 school districts; the book presents a roadmap for implementing similar programs in other school districts, targeting teacher retention, teacher development, and fostering student growth. Readers will find detailed explanations of key program components, and the vital roles of district science coordinators and higher education institutions. Through a mix of theoretical insights, practical strategies, and testimonials from program participants, the book provides a comprehensive model for educators, administrators, and university leaders who aspire to replicate or adapt the SEF program in their own contexts. Ideal for both educators and school administrators, this book will allow you to gain valuable insights into building and sustaining a program that empowers teacher-leaders, drives district-wide transformation, and ultimately improves student outcomes in science education.
