The “jigsaw” is a collaborative class activity that can be useful when you’re asking students to manage a large amount of material or to grapple with a complex problem.
It allows students to divide up the work into more manageable pieces that they then share with each other.
In the first stage of the jigsaw, students are divided into groups who are each charged with a different task, typically one that involves that group becoming an “expert” on a particular topic or question.
In the second stage, the groups are remixed so that at least one student from each original group is now part of a new group. Those representatives then share what was discussed in their original groups. In this way, all students get to learn what was discussed by all the groups.
In other words, if you started out with group A (A1, A2, A3), group B (B1, B2, B3), and group C (C1, C2, C3) as the expert groups, you’d then have students move to group 1 (A1, B1, C1) group 2 (A2, B2, C2) and group 3 (A3, B3, C3) for their sharing groups.
A simple jigsaw might ask each initial group to come up with a definition for a different key term. Then, once students move into their new groups, each student shares their group’s definition with the others in her new group. In this way, each student will get to learn all the groups’ definitions.
