This series of brief videos (1-10 min. each) demonstrates how a three-part lesson in a classroom focused on accountable talk empowers and engages students to learn through collaborative problem solving in a technology-rich environment. While solving a problem involving rates and proportional reasoning students exemplify shared criteria for successful group work. The teacher explains her strategies for planning, grouping, and peer evaluation. Print resources (pdf) include a Viewer's Guide, organizers, and supporting monographs.
