Simple Jigsaw

Jigsaw is a cooperative learning strategy that enables each student of a “home” group to specialize in one aspect of a learning unit. Students meet with members from other groups who are assigned the same aspect, and after mastering the material, return to the “home” group and teach the material to their group members.

Just as in a jigsaw puzzle, each piece--each student's part--is essential for the completion and full understanding of the final product. If each student's part is essential, then each student is essential. That is what makes the Jigsaw instructional strategy so effective.

Jigsaw learning allows students to be introduced to material and yet maintain a high level of personal responsibility.

The purpose of Jigsaw is to develop teamwork and cooperative learning skills within all students. In addition it helps develop a depth of knowledge not possible if the students were to try and learn all of the material on their own. Finally, because students are required to present their findings to the home group, Jigsaw learning will often disclose a student’s own understanding of a concept as well as reveal any misunderstandings.

The Process:

The teacher divides an assignment or topic into four parts with all students from each LEARNING TEAM volunteering to become "experts" on one of the parts. EXPERT TEAMS then work together to master their fourth of the material and also to discover the best way to help others learn it. All experts then reassemble in their home LEARNING TEAMS where they teach the other group members.
