The Jigsaw Classroom

The Jigsaw Classroom is a cooperative learning technique created by Elliot Aronson in 1971. The content to be learned is divided into 4 to 5 complementary parts, with each learner responsible for one part. Participants first work among 'experts', then return to their home group to teach their piece to others. This setup creates positive interdependence: everyone needs each other to understand the whole.

Walkthrough

1. 1

   Frame the objective and the logic of the puzzle

   5 to 10 min

   The facilitator presents the theme to be learned and clearly announces the principle: 'The content is divided into 4 to 5 parts; no one will have everything at the start.' They explain that everyone must understand one part and then teach it to their home group. Participants listen, ask clarifying questions, and identify the collective stakes. The goal is to immediately create positive interdependence: success requires learning and teaching.

   Tip — Emphasise the dual responsibility: 'you are a learner at first, then a teacher later'. This prevents some from reading only for themselves.

2. 2

   Form the home groups and distribute the parts

   5 to 10 min

   The facilitator divides the 9 to 40 participants into home groups, ensuring that each group can cover the 4 to 5 parts of the content. They assign each member a different part: 'You are piece A, B, C, D, possibly E, of your group.' Each participant receives only their part and checks that they know which home group they will join later. This step establishes the structure: each piece becomes essential to understanding the whole.

   Tip — Have everyone note their home group and part before moving. In person, a colour code or visible letter significantly reduces time lost during group changes.

3. 3

   Individual work on their part

   5 to 15 min

   The facilitator gives silent time to read, annotate, and identify the key points of their part. They say: 'Your goal is not only to understand but to prepare what you will need to convey.' Participants highlight key ideas, note questions, and identify useful examples. This individual time prevents expert groups from starting too quickly with vague or unevenly prepared exchanges.

   Tip — Ask for a simple output before the expert regrouping: three key ideas and one question. This provides a common foundation without imposing a heavy method.

4. 4

   Gather the expert groups

   10 to 20 min

   All participants with the same part gather in expert groups. The facilitator gives the instruction: 'Agree on what must absolutely be understood, in what order, and with what explanations.' Experts compare their understanding, clarify ambiguities, and prepare a mini-explanation for their return to the home group. The goal is to secure the content and make everyone capable of teaching their piece.

   Tip — Circulate mainly to listen to the formulations. If an expert group produces a summary that is too long, bring it back to the essentials: what others need to remember to understand the whole.

5. 5

   Return to home groups and cross-teaching

   15 to 30 min

   Each participant returns to their home group and teaches their part to the others. The facilitator specifies: 'In turn, each explains their piece; the others listen, question, and take notes, as the quiz will be individual.' Group members gradually reconstruct the complete content from the 4 to 5 contributions. This sequence is the heart of the Jigsaw: no one can succeed alone, and every explanation counts.

   Tip — Announce an equitable time for each person, even without timing down to the detail. The more comfortable participants tend to take more space; remind them that each piece is equally important.

6. 6

   Consolidate the overall vision

   5 to 10 min

   The facilitator asks the home groups to check together that they have connected all the parts. They might say: 'What becomes clearer when we assemble the pieces? Where do you still see a grey area?' Participants reformulate the overall thread, complete their notes, and ask the final questions for understanding. This step transforms a juxtaposition of presentations into integrated learning.

   Tip — Have participants formulate the synthesis, not the facilitator. Your role is to identify confusions and have them clarified by the group when possible.

7. 7

   Evaluate individually and conclude

   5 to 15 min

   The facilitator concludes with an individual assessment or quiz, as the method prescribes. They announce: 'You will answer alone, based on what you have learned from your part and from those conveyed by others.' Participants complete the assessment, and then the facilitator can correct or revisit sensitive points. This ending values the attention given to peers and checks that learning has been shared.

   Tip — Keep the individual quiz: this is what makes listening to others truly engaging. Announce it from the start to create active attention during the cross-teaching.

Variants

• Short version: reduce the content to 4 parts and limit the expert work to identifying key ideas. This variant is suitable when the goal is mainly to introduce a topic rather than to deepen it.
• In-depth version: ask each expert group to prepare a verification question for their part. During the return to the home group, each expert teaches and then poses their question to the others.
• Remote version: use virtual rooms for the home groups, then redistribute participants into expert rooms according to their part. Plan a shared document by part and a common support for the final synthesis.
• Large group version: with a number close to 40, prepare the composition of the groups and the assignments A, B, C, D, possibly E in advance. This limits movement and makes transitions smoother.
