Group work — learning and graded work produced by a team rather than an individual, used to develop collaboration, communication, and shared responsibility while also generating an outcome and often a grade for each member. It sits where assessment design and collaborative learning meet, and it inherits the tensions of both: free-riding and social loafing, unequal contributions, conflict avoidance, and the difficulty of attributing a collective product to individual learning. Generative AI intensifies these because teams must now negotiate whose and what kind of AI engagement counts as acceptable — a negotiation that Agency research shows can resolve in opposite directions within a single cohort, and that AI agents joining the group can themselves reshape.

Questions to Consider

  • What is a group task actually producing — the group's output, each member's learning, or their ability to collaborate? If those three can diverge, which one does your grading claim to warrant?
  • Think of a group project you have been part of. Who did the work, who decided what counted as good work, and who stayed quiet? How much of that was the task design rather than the people?
  • Research on group work finds students often decline to hold free-riders accountable to protect relationships. When a group member uses GenAI to produce their section, is that free-riding — or is the judgment more complicated than the word suggests?
  • A group can access AI through a single shared interface or through each member's private prompts. Which produces more honest collaboration, and what does each conceal?
  • If an AI agent joined your group as a teammate — praising, questioning, or provoking — would it deepen the collaboration or reshape who drives it without anyone noticing? How would you tell the difference?
  • Collaborative AI that maximises task efficiency tends to minimise learners' self-regulatory engagement. If you had to choose between the outcome and the struggle, which would you protect?
  • A mediator AI is trusted only while it stays neutral. When it moves from summarising to advising or challenging, the trust erodes. How neutral should a group's AI really be?

Introduction

Group work occupies a distinctive place in higher education and professional training: it is valued for building collaboration, communication, and shared responsibility, and it is pedagogically central in professionally oriented programmes such as teacher education. Its promise is not automatically realised, however. Both teachers and students report obstacles to effective collaboration, and a graded group product carries two different claims at once — about what the group accomplished and about what each individual learned. AI, and generative AI in particular, presses on both: it changes how work can be divided, how easily contributions can be fused, and how each member's thinking can be distinguished from a tool's output. A large part of the knowledge base's collaborative-learning research bears on group work, and this page draws on several strands of it rather than any single study.

Why group work is difficult by design

  • Free-riding and social loafing. Some members reduce their contribution and the workload is redistributed onto more engaged peers. Task scope, group size, and composition raise the likelihood; accountability mechanisms and group efficacy reduce it.
  • Accountability is relational as well as structural. In Hong Kong — where one of the knowledge base's group-assessment studies was conducted — undergraduates often chose not to report free-riding to protect interpersonal relationships, completing the work themselves instead of confronting the problem. Students' Agency can therefore take the form of pursuing the grade while avoiding the conflict.
  • The collaboration has to be designed, not assumed. Where a task can be partitioned into independent subtasks, students take that route and the group becomes a submission format rather than a joint intellectual endeavour. Chen and Zou (2026) found three of their fifteen groups doing exactly this — dividing the work, working on "individual platforms," and never pooling their individual GenAI capabilities even when coherence was an explicit assessment criterion.
  • Process versus product. Group work is strongest when the process is assessed alongside the output, which requires peer review or other visible intermediates rather than a single final artefact.
  • Equity and inclusion. Contribution norms, language, and confidence distribute unequally inside groups. Neurodivergent students report needing structured assignments, small consistent teams, and explicitly defined roles — requirements that AI collaboration tools, often built for the "average" learner, routinely fail to accommodate.

How AI changes group work

Research on AI in group work addresses two distinct things: what AI adds to a group's task, and what AI does to the group's process. Both matter, and the knowledge base's findings span them.

AI as coordination infrastructure

The most direct finding on GenAI and group assessment is Chen and Zou's (2026) three-pattern study of fifteen pre-service teacher groups. Rather than a single enthusiasm-to-avoidance spectrum, agency ran in three directions at once.

Pattern Groups Practice Rationale
Cooperation-oriented agency 5 Intensified GenAI use Coherence, performance, shared norms lowering perceived risk
Normative agency 7 Deliberately restrained use Authenticity, fairness, originality, diversity of perspectives
Non-enacted agency 3 Unchanged from individual work Task partitioned; collective interaction viewed as costly
  • GenAI as coordination infrastructure. Students intensified use to solve a familiar collaboration problem — not knowing what peers' sections contained. Feeding those sections into a chatbot to decode and align them made distributed knowledge mutually intelligible, and one group rebuilt its workflow as "discussion → externalisation to GenAI → collective review → re-discussion." The authors read this as going beyond cognitive offloading, since judgement stayed with students while the tool absorbed coordination work, while warning that the smoother workflow may bypass the disagreement through which cohesion is built.
  • Group norms can invert accountability. A permissive collective climate lowered the perceived risk of misuse ("it is more comfortable because besides me, everyone in my group is using GenAI"), turning shared norms into shared risk management rather than commitment to learning — the opposite of what group accountability is meant to achieve.
  • Restraint is also agentic. Seven groups cut their GenAI use to protect the task's situated knowledge ("AI only knows that moment when you type"), to avoid effectively free-riding on groupmates, to preserve the originality that distinguishes groups from one another, and to keep the diversity of perspectives the group already had — normative self-regulation rather than mere compliance, and hard to distinguish from disengagement from the outside.

How the group accesses AI shapes the collaboration

Xu et al. (2026) show that how a team accesses GenAI is itself a design decision. With a single shared interface in synchronous work, teams co-construct "collective prompts," run a surface–evaluate–embed cycle, and treat the chat as shared memory; in asynchronous work, private prompting and output "de-labelling" fragment transparency and raise the cost of sustaining a shared cognitive model. Access configuration therefore connects directly to the quality of interactive engagement — whether the group is genuinely co-constructing or merely co-approving.

AI as a group member reshapes the group

A second line of research treats AI as a participant rather than a tool, and its findings complicate the assumption that "AI teammate" means "better teamwork."

  • Agents as social stabilizer — and a magnet for questions. In fifteen groups of three STEM students deliberating Ethics with three LLM participants (Seo et al., 2026), the agents kept groups on topic when human members drifted ("even if the other two participants strayed, I didn't have to handle it") and prompted clarifications humans avoided for relational reasons. But the group dynamic shifted interaction away from humans — 79.7% of questions were directed at agents (p = .017) — and participants noted a breadth–depth trade-off in the turn-stacking format, where each speaker took the floor in turn and "other participants couldn't intervene," making it easy to cover many ideas but hard to explore any one in depth.
  • AI personas reconfigure emergent Agency. Jin et al. (2026), in an experiment where AI operated as an undisclosed teammate, found supportive and contrarian personas still reshaped the group: contrarian AI pulled discourse toward challenge and reflection (productive friction), while supportive AI stabilised agreement and renewed ideation. Critically, the friction had a affective cost — contrarian AI reduced teamwork satisfaction and psychological safety without yielding creative gains — so "productive" discourse structures must be weighed against their emotional consequences. Because the personas worked even without disclosure, they position persona design as a form of invisible Governance over group collaboration.
  • Controversy can counter groupthink. Wiss et al. (2025) took the opposite tack deliberately: an AI agent (CALIE) prompted to inject controversial viewpoints into twelve interprofessional PBL teams stimulated critical thinking and positive group dynamics, countering the conformity pressure that group work can otherwise produce. The contrast with Jin et al. is instructive — challenge helps when it is the intended design, and hurts when it is an unacknowledged side effect.
  • The neutral-mediator constraint. Spritz, an AI that mediates disciplinary boundaries in interdisciplinary teams by surfacing implicit assumptions, was valued as both cognitive support and a relational buffer — but students' trust was load-bearing and eroded the moment the AI moved from neutral mediator to advisor or challenger. Role switches therefore need to be explicit and configurable, not silent.
  • Collaboration can itself be the object of instruction. ProPACT treats the dyad — not the individual — as the unit of analysis, modeling joint attention and effort to predict collaborative breakdowns up to 30 seconds in advance. Dyads receiving proactive feedback achieved higher debugging success and showed sustained gains in collaborative Regulation afterward: AI can teach collaboration itself, not just support a task.

The efficiency–regulation trade-off

Hao et al. identified three collaborative modes with AI on complex problems — Delegated Reasoning, Concerted Interpretation, and Delegated Elaboration. The most efficient mode (delegated reasoning) yields the best task performance but the lowest self-regulatory engagement; the mode with greatest self-regulation (concerted interpretation) underperforms on the task. This is the central design tension for AI-mediated group work: balance the efficiency of the distributed human–AI system against the depth of learners' regulatory engagement.

The epistemic risk of polished output

Kimmerle conceptualises the risk of reduced epistemic effort when learners use AI to produce polished knowledge artifacts — automation bias on the social-cognitive side and epistemic closure induced by the finished artifact on the other. The remedy is to structure AI as an argumentative partner or challenger that preserves conflict. The counterpoint comes from Oppenheimer et al., who found that when LLMs act as critique partners and students actively rebut their claims, learners behave as critical consumers who preserve rather than surrender the cognitive conflict of critique. The difference between an answer-giving teammate and a challenging partner is what determines whether group work with AI builds or bypasses thinking.

Classroom-level, non-evaluative support

CoBi detects "uplifting" small-group discourse (respect, equity, community, moving thinking forward) and returns non-evaluative, classroom-level visualisations — deliberately withholding student- or group-level feedback to protect Privacy and Trust. Students preferred qualitative visualisations (an organic tree) over quantitative ones (a radar chart). For the relational dimension of group work, class-level aggregated feedback supports community building where individual scoring would feel surveilled.

Design implications

  • Make the AI-use negotiation an assessable outcome. Chen and Zou (2026) argue teams should justify and document how GenAI will and will not be used, turning an implicit peer norm into explicit, gradeable reasoning rather than leaving it to perceived risk.
  • Assess process, not only product. Peer review, intermediate deliverables, and reflective contributions create the interactions through which norms and shared understanding are actually constructed.
  • Do not rely on a coherence criterion alone. A rubric line demanding integration does not produce collaboration if the task structure still permits divide-and-conquer; the workflow has to require joint work.
  • Design access deliberately. Whether the group shares one AI interface or each member prompts privately changes the transparency of the collaboration and the cost of sustaining a shared cognitive model.
  • Decide, visibly, what the AI's role is. A neutral mediator is trusted; an advisor or challenger is not, unless that role is explicit and intended. A contrarian persona can counter groupthink, but only as a designed feature with its psychological-safety costs acknowledged.
  • Balance efficiency against self-regulation. Collaborative AI that maximises task efficiency can undercut learners' regulatory engagement; design should deliberately protect space for concerted interpretation.
  • Prefer an argumentative partner over an answer-giver. Structure AI to surface disagreement rather than smooth it over, so group work preserves the cognitive conflict that builds understanding.
  • Accommodate neurodivergent learners. Structured assignments, small consistent teams, and explicit role definitions are requirements AI collaboration tools must support.
  • Read restraint carefully. Students who avoid AI in groups may be exercising normative self-regulation — or guarding against risk and unfamiliarity. The two call for different instructor responses.
