What kind of supports would keep teachers well equipped to help all of their students succeed? What if these same supports kept teachers energized, passionate, and informed about their fields? Content-Focused Coaching offers just such a sustaining system. CFC is a long-range professional development practice in which coaches work individually or with groups of classroom teachers to design, implement, and reflect on rigorous, standards-based lessons that promote student learning. Authored by two educators closely involved with the design of CFC, this book is perfect for K-8 staff developers, teacher leaders, administrators, and others interested in improving mathematics education.
