Transform classrooms and student performance with evidence-based, effective practices. Two brains are better than one, as the saying goes, and this is especially true in education. Educators who employ effective collaboration and co-teaching greatly amplify student engagement, achievement, and growth, particularly for those learners needing extra support. Written by two of the nation's top experts in co-teaching, this book is an essential, reader-friendly guide for educators and instructional leaders who are passionate about creating truly inclusive classrooms where all students thrive - academically, behaviorally, socially, and emotionally. Inside, the authors provide three clearly defined steps to build a strong foundation, leverage collaboration, and support students' growth; a laser focus on high-leverage and evidence-based practices for general and special education that optimize educators' impact, including collaboration, instruction, assessment, and social emotional/behavior skills; seamless integration of practices within MTSS and RTI processes to meet the needs of all learners; and countless concrete samples, examples, tools, reflection exercises, and supplemental materials that enable you to move from theory to immediate instructional practice. Positioning collaboration as the catalyst to maximizing high-leverage and evidence-based practices for the success of all students, this easy-to-use handbook belongs on the desk of every teacher working toward a truly inclusive environment.
