Group Work
A learner interaction format where three or more learners cooperate on a task, typically with assigned or emergent roles. Distinct from pair work in that group dynamics — turn distribution, role allocation, dominant voices — become a managed variable rather than incidental.
Common task types
Jigsaw: each group member receives a different piece of information, and the group reassembles a complete picture by sharing. Forces every member to contribute and rewards careful listening, since no one has the full answer alone.
Ranking and consensus: groups order items, prioritise options, or agree on a list. Designed to generate negotiation language (agreeing, disagreeing, conceding, justifying) that pair work struggles to produce at length.
Task-based projects: a group works across multiple stages (research, drafting, presentation) with sustained collaboration over a lesson or longer. Closer to real-world group output and reveals collaboration skills the shorter formats miss.
Problem-solving and information-gap: groups work towards a single solution where each member holds different inputs, similar in principle to jigsaw but with a problem rather than a reconstruction goal.
Group size effects
Threes are the smallest stable group: one member can step back and the task continues, but the dynamic is closer to a pair than a true group. Fours allow paired sub-conversations and balanced turn distribution and are often the optimum for discussion tasks. Fives and sixes produce richer ideas but reliably leave one or two members silent unless roles are assigned. Beyond six the format collapses, with most members becoming passive observers.
Cooperative learning research
Robert Slavin's synthesis of cooperative learning research argues that group work raises achievement only when two conditions are met: group goals (the group succeeds together) and individual accountability (each member's contribution is assessable). Without these, stronger members carry the task and weaker members coast. The methods Slavin documents (STAD, TGT, Jigsaw II, TAI, CIRC) operationalise both conditions in different ways. The implication for ELT is concrete: assigning a group task without role assignment or individual output requirements typically reproduces the strongest-member-does-it pattern.
Setup
Groups need explicit roles for non-trivial tasks (a recorder, a reporter, a timekeeper, a language monitor), assigned at the start and rotated across lessons. Furniture matters: rows seating cannot support real group work, while clustered tables make it default. Reporting back is what makes group work accountable; without a reporting stage the group sees the task as private and effort drops.
