Discover the true value of classroom walkthroughs when they are formative, not summative; supportive and collegial, not punitive or negative. Two of ASCD's most popular authors Connie Moss and Susan Brookhart team up to equip you with a formative walkthrough approach that capitalizes on an observation process and feedback protocol that focus on what students are doing and learning. A set of Collaborative Inquiry Guides included in the book help ensure this formative walkthrough process informs teachers, coaches, principals, and others about what they need to learn and do to move instructional practice forward.
