Book excerpt: Math coach, Kassia Omohundro Wedekind and literacy coach, Christy Hermann Thompson, have spent years comparing notes on how to build effective classroom communities across the content areas. How, they wondered, can we lay the groundwork for classroom conversations that are less teacher-directed and more conducive to student-to-student dialogue? Their answers start with Hands-Down Conversations, an innovative discourse structure in which students' ideas and voices take the lead while teachers focus on listening and facilitating. In addition to classrom stories and examples, Christy and Kassia provide 28 micro-lessons designed to help K-5 students develop and excercise their speaking and listening muscles. Inside Hands Down, Speak Out you'll learn how to: Build talk communities that are accessible to everyone, especially those whose voices are often traditionally left out of classroom discourse. Analyze classroom conversations in order to plan next steps for developing the classroom talk community Plan and facilitate three types of conversations across literacy and math Christy and Kassia believe that the development of dialogue skills is worth the investment of time not only becuase it has the power to deepen our understanding of literacy and mathematics, but also to deepen our understanding of ourselves, our communities, and the world.
