How are expert groups organised in a jigsaw activity?
A jigsaw divides a topic into complementary parts that students study and later explain in newly formed groups. Learners first develop knowledge of one part, then learn the others from peers. Successful design links the parts to a common question and makes each contribution necessary; simply distributing sections of a text is insufficient.
From expert group to mixed group
For a local water-supply problem, groups might examine consumption, infrastructure, climate and conservation data. Students studying the same part first identify findings, evidence and difficult points in expert groups. Mixed groups then include one representative from each part. Each learner explains their section, others ask questions, and the group builds a shared solution table. The teacher balances source difficulty, clarifies timing and listens to expert groups to prevent errors spreading.
Checking individual understanding too
An attractive group poster does not show that every member has learned the topic. Ask each student to explain connections among all parts or answer an individual question afterward. One unprepared member can affect the group, so plan backup resources and teacher support. Students should know that asking for clarification is normal. The technique works best when parts connect meaningfully and may not suit every topic or lesson length. Assessment should focus on accurate use of evidence and integration, rather than performance as a speaker alone.
