A well-managed classroom almost runs itself. Students are focused and respectful, whether they are silent at their desks or active throughout the classroom-collaborating, experimenting, discovering, and creating. This book is a guide for teachers who want their classrooms to run well in all settings, where students are self-directed and self-disciplined learners. It is a book of proven, practical strategies harvested from successful schools across the United States. Strategies are described in concrete language, illustrated through classroom examples, and illuminated by companion videos. This guide will equip teachers, whether veterans or brand-new, to join inspired, collaborative learning with a calm and thoughtful classroom culture.
