The book that started it all—is completely revised. Why would the Kagans update a classic that has sold nearly half a million copies? The answer: So much has changed. Cooperative Learning today is different. This new book presents today's most successful cooperative learning methods. The Kagans make it easier than ever to boost engagement and achievement. You'll still find all the practical and proven Kagan Structures, including Numbered Heads Together, RoundTable, and Three-Step Interview—direct from the man who invented cooperative learning structures. And there's still plenty of ready-to-do teambuilding and classbuilding activities to make your class click. But in this expanded edition, you will find new step-by-step structures, hundreds of helpful management tips, many more teacher-friendly activities and forms, and up-to-date research on proven methods. You hear how schools have used Kagan Cooperative Learning to boost academics, close the achievement gap, improve student relations, and create a more kind and caring school community. After decades of training and working with hundreds of thousands of teachers, Kagan has refined and perfected the most widely used and respected form of cooperative learning ever. The Kagans make it easy for you to dramatically increase engagement and achievement in your class.
