The Common Core State Standards are at the center of the latest firestorm in American education reform. But this is not the nation’s first torrid experience with standards implementation. In Challenging Standards, Jonathan Supovitz and James Spillane bring together the collective knowledge of top education researchers who have both experienced and investigated education reform challenges in the past. Combining both evidence-based research and applied knowledge, the contributors share with educational leaders their accrued wisdom about implementing standards in classrooms and systems, building capacity through relationships, and navigating the fractious political terrain. Each section of the book contains a set of facilitative questions that will help leadership teams, book clubs, and professional learning communities connect the chapters to their work.
