Jigsaw is a cooperative learning strategy where students are assigned different aspects of a topic to become "experts" on. They then teach their topic to their home group. The purpose is to develop teamwork, responsibility, and a deeper understanding than learning individually. To implement jigsaw, topics are divided among expert groups who then teach their home groups. Assessment ensures all students mastered the material. Cooperative learning similarly aims to develop academic and social skills through heterogeneous groups working interdependently to achieve goals. Various roles foster accountability while social skills and group processing are emphasized.
