Content-Focused Coaching (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. This book is for K-8 staff developers, teacher leaders, administrators, and others interested in improving mathematics education. It explains the general tenets of CFC and the fundamental foundations upon which it rests. It then provides examples of coaching in action in New York City's Community School District #2, a district known nationally for its progressive, innovative, and rigorous focus on professional development. The three accompanying CD-ROMs contain video footage of coaching sessions including the pre-conference, lesson, and post-conference. (KHR)
