I read this book my masters course on Leading School Improvement. I loved it!! How often can you say that about required reading? This book explains that many schools seek reform by modifying structure (building, scheduling, technology), samples (the different ways students are organized into learning groups), and standards (the curriculum and learning goals) which in and of themselves lead to limited changes in students' learning experiences and achievement. The levers of strategies (teachers' decisions inside the classroom) and self (fixed vs. growth mindset, motivation, engagement, self-efficacy, ownership of learning) on the other hand provide the most torque in driving meaningful changes in student learning. This a must read for all teachers, school leaders, and stakeholders in education so that effort, time, and resources are properly used to make meaningful, lasting change.
