"This book is about teachers and the conditions under which they can improve together. It is filled with big ideas about getting better, practical insights from the field, and step-by-step guidance through the practice improvement process called Teaching Sprints. Whether you're an educator, instructional coach, school principal or system leader, we hope this book helps you to explore key questions that are important to you: How can teachers focus on improving, when they're already overwhelmed by the extreme demands of teaching? How can we provide the opportunity for all teachers, regardless of experience and expertise, to incrementally improve their practice in every term, every year? What "big ideas" are important to know if I want to improve my own professional learning, or the professional learning opportunities of my peers? How can we sustain a focus on teacher learning through the regular pressures of a school year? What is Teaching Sprints, and how have others used this simple process to drive lasting practice improvements in the field?".
