Cooperation in the Classroom : The Jigsaw Method (3rd Revised edition)

The jigsaw classroom is a cooperative learning technique with a three-decade track record of successfully reducing racial conflict and increasing positive educational outcomes.

Not only does it open the door to warmer, closer friendships within and across ethnic boundaries, it has also proved effective at raising the self-esteem of students while improving their performance and increasing their liking for school and their enthusiasm about learning. The jigsaw technique was first developed in the early 1970s by psychologist Elliot Aronson and his students at the University of Texas and the University of California.

Since then, hundreds of schools have used the jigsaw classroom with great success. With a new foreword by Joshua Aronson.
