Building on both cutting-edge research and professional learning practice, Amanda Datnow and Vicki Park explore how professional collaboration can support deeper learning for students and teachers alike. While many schools and systems support teacher collaboration, they often fall short of their intended goals of improving teaching and learning. This book provides concrete guidance for creating the conditions for collaboration in which teachers are moved toward--rather than repelled--by joint work. The authors explore how collaborative settings can provide a space for working through the inevitable challenges that accompany the changing nature of teaching in the age of accountability and show the motivation, inspiration, and energy that teachers personally--and collectively--gain from collaborating to improve student learning. Ultimately, they show how teacher empowerment towards working together builds equitable and excellent learning environments.
