The document outlines the steps to conducting a jigsaw activity in the classroom which involves dividing students into groups, assigning each group a topic to research, regrouping the students so that one "expert" from each original topic is in a new group to teach their topic to their peers, and then regrouping again for students to share what they have learned from the experts. The purpose is for students to teach other students, improve diversity and collaboration, and reinforce cooperative learning. Potential downsides are students getting distracted, not participating, and needing teacher oversight to confirm accuracy.
