It’s a fact that effectively managed classrooms can make a huge difference on students’ achievement gains – maybe as much as 20 percentile points. What hasn’t been clear is what teachers actually do to create effectively managed classrooms. Now, here’s a book that draws from more than 100 studies of classroom management to explain the four most important general components of effective classroom management and their impact on student engagement and achievement. Based on the concepts from What Works in Schools: Translating Research into Action, Robert J. Marzano describes the action steps you need to take to establish rules and procedures, use effective disciplinary interventions, build positive student-teacher relationships, and develop a sound mental set to get you through the most difficult situations. Real classroom stories illustrate how to get every class off to a good start, involve students in classroom management, and develop effective schoolwide management policies.
