Now in a revised and updated second edition addressing the evolving needs of today's K-12 educators, this established classroom resource is written by leaders in positive behavioral interventions and supports (PBIS). Brandi Simonsen and Diane Myers provide a vital classroom management and behavior support toolkit with a primary focus on universal (Tier 1) support. In a convenient large-size format, the book provides step-by-step guidelines for structuring the classroom environment, actively engaging students in instruction, setting clear expectations, and implementing a continuum of strategies to reinforce positive behavior and respond to inappropriate behavior. Teacher-friendly features include classroom vignettes, bulleted chapter objectives, end-of-chapter learning activities, and reproducible forms that can be downloaded for repeated use. New to This Edition: (1) Expanded focus on culturally responsive and inclusive practice; (2) Increased attention to connecting with students and families and engaging them in designing, implementing, and monitoring practices; (3) More coverage of integrating Tier 2 and Tier 3 interventions into a classwide PBIS model; and (4) Updated research, resources, tools, and examples throughout the chapters.
