Conditional relationship¶

This page owns the structure of dependence among group members: how a task, its resources, its roles and its reward make one learner's success depend on the others', and what that changes. For learners who can already contribute to the task, working in small groups over several weeks, making the group's success depend on every member's learning (a shared goal, with group recognition computed from each member's individually assessed learning, and where useful distinct roles or resources) is expected to make members explain to, help and hold one another to account, and so to raise individually measured achievement (general-achievement, conceptual-understanding) relative to independent or competitive work. Dependence without individual accountability is not this relationship: a single group product or grade lets some members share the outcome without the learning.

Claims test parts of this, not the whole. In school studies of four weeks or more, group rewards resting on each member's individual learning went with larger achievement effects than a single group product or no group reward, and one randomised component study with at-risk 4th and 5th graders found reward plus structured peer tutoring best. Against that, the one experiment in the wiki that varied the type of interdependence (role, reward, both or neither, in asynchronous online triads of undergraduates) found no achievement difference, though the types changed how groups talked and how members felt about the work. No claim varies goal or resource interdependence on its own with accountability held constant, or sets a group size, composition or duration. The evidence is mostly from pre-k-12 and postsecondary classrooms, on course or general achievement at the end of multi-week programmes; it does not forecast a single session, a workplace team or an individual learner.

How the converted siblings sit around this: Cooperative Learning holds the comparison of structured cooperative work with individualistic and competitive arrangements, and its model takes interdependence plus individual accountability as given; this page sits inside it and asks which form of dependence to build and what it does. Collaborative Learning holds the broader question of when joint work of any structure changes what each learner can do. The cooperative learning pattern carries a reusable sequence; its branches are untested proposals.

Default design, while the relationship is untested¶

The earlier page's guidance (Johnson & Johnson's four requirements and Cohen's rich group task), kept as a concrete default and extended into an arc across sessions. The relationship as a whole is untested here; each step says what evidence, if any, stands behind it.

Give the group a reason to need every member. Set one shared goal that no member can reach alone: a product or decision that needs information, skills or perspectives held by different members (resource or skill interdependence), not identical subtasks split up. A "rich group task" needs a diversity of skills (for example writing, performance and art for a presentation), so each distinct contribution is necessary. From the earlier page (Cohen, Brody & Sapon-Shevin, 2004); untested here as a comparison.
Compute the group's recognition from each member's own learning. After each cycle, every member takes a short individual check (a 5–10 minute quiz or explanation task, a proposal); the team's score is the sum or average of members' individual scores, or of their improvement over their own previous score, so helping the weakest member counts most. Evidence: group rewards based on members' individual learning [+M] (school studies of four weeks or more, and one component study with 4th and 5th graders). Improvement-based scoring rather than ranking is from that claim's Discussion; untested here.
Make each member's part visible. Rotate a randomly chosen reporter, ask each member to explain a part of the product they did not write, or record who did what. This guards against freeloading (some members doing little) and against overspecialisation (members splitting the task to reduce effort without integrating their reasoning), the two failure modes the earlier page names. Evidence for the danger: free-riding without individual accountability [~M]; the specific moves are untested proposals.
Give time and a place to work together, in class. Interdependence on paper, with the joint work done outside the session, is not the requirement. Plan 15–25 minutes of in-session group work per cycle (a proposal), with the teacher circulating. From the earlier page (Johnson & Johnson, 1998; Smith et al., 2005); untested here.
Teach working-together skills explicitly. In the first two sessions, model and practise one or two skills each time (asking for and giving an explanation, checking that everyone agrees and why, disagreeing with a reason). From the earlier page; untested proposal.
Close each cycle with a short review of how the group worked. Three to five minutes: one thing that helped, one to change, recorded. Untested proposal (group processing, from the cooperative-learning tradition).
Plan the arc across sessions. A default for a unit of four to six weeks, the duration the reward evidence comes from:
Weeks 1–2: pairs or groups of three, kept stable; assigned roles with role cards; short, tightly bounded tasks; teacher-chosen interdependence (each member holds one resource); team score from individual quizzes after each cycle; skills taught explicitly.
Weeks 3–4: groups of three or four; roles rotate each cycle; tasks become richer and need integration of members' parts; role cards are withdrawn once the group is doing the role's job without them.
Weeks 5–6: groups plan their own division of work and must justify how each member's part feeds the whole; the individual check moves to the form of the final assessment (unaided, changed items). Move a group on when every member's individual check is at the locally set criterion on two consecutive cycles; keep a group at the earlier stage, or regroup, if one member's individual scores stay low while the group product is good. The arc, group sizes and criteria are untested proposals.

When a condition is not met: if no group recognition is allowed (individual grading only), keep the structure (roles, resources, a script for peer explanation) and the individual checks and drop the reward; one review reports that structured interaction can raise achievement without a group reward (group rewards and individual accountability [~M]). If the group work is asynchronous and online, do not expect role or reward structure to raise achievement by itself (below).

Fitting the design to a situation¶

The three facts that most change the decision:

What, exactly, each member's success depends on, and how it is checked. A shared grade on one product, a team score built from individual quizzes, and a role that others need are three different structures with different failure modes. If unstated, ask: how will the grade or recognition be computed, and how will you know what each member can do alone?
Whether members can contribute. Dependence on a member who does not yet know enough produces copying or resentment, not explanation. If unstated, ask: can each member, alone, do or explain a first part of this task now?
Setting and duration. The achievement evidence comes from face-to-face school and undergraduate classes over several weeks; the one online experiment found no achievement effect of interdependence type. If unstated, ask: will the group meet live, for how many sessions, and over how long?

If the brief says…	Then change…	Basis
Learners are `child` (upper primary), or at risk of failure	Use pairs with scripted tutor and tutee roles, switching each session; team score = sum of both members' daily individual quiz scores	Group rewards combined with individual accountability [+M] (64 at-risk 4th and 5th graders, maths computation; reward plus structure best; effect figures second-hand)
Learners are `adolescent` (early secondary)	Use cooperative goal structures as the default arrangement for multi-week units, with individual checks feeding a team score	Cooperative learning improves achievement [+S] (meta-analysis of 148 studies of early adolescents, direction only; Learning Together method d = 0.70–0.91 from an unpublished report)
Learners are `adult` / `postsecondary`, in a live course	Use small structured groups for problem sets, labs and design tasks, with individual assessment kept separate from the group product	Small group learning improves STEM achievement [+M] (39 undergraduate STEM studies, d = 0.51; compared groups with non-group instruction and does not isolate interdependence)
Setting is `online-self-paced` or asynchronous online groups	Do not rely on assigned roles or a group reward to raise achievement; require each member to post a stated number of contributions that respond to others', and assess individually	Interdependence type did not affect posttest achievement [~M] (280 undergraduate business majors, triads; non-significant, no effect size); more interactions went with higher posttest scores [+W] (same study, correlational)
The aim includes participation, sense of obligation or attitudes to group work	Assign roles or a group reward: members in any structured condition agreed more that teammates' duty to contribute helped them learn; reward groups agreed more that they gained from others	Structured interdependence and obligation to contribute [+M]; reward interdependence and benefit attitudes [+M] (self-report, same online study; not achievement)
Learners are `novice` on the content, or members differ widely in what they know	Teach and model the content first; use interdependence for practice and explanation, not first acquisition; set improvement-based team scores so low starters can contribute	untested proposal; improvement-based scoring from the Discussion of group rewards combined with individual accountability [~M], not from its entries
Time is one session only	Use pairs, one short shared task, and an individual check at the end; do not claim an achievement effect	untested; the reward evidence comes from programmes of four weeks or more (free-riding without accountability [~M])
Group size is open	Prefer pairs for tightly coupled tasks and three or four for tasks needing several skills; watch for a member drifting out in larger groups	Pairs worked better than triads in one inquiry [~W] (authors' teaching experience, one astronomy activity, no measured outcome)
The structure is Jigsaw or another resource-only design	Add an individual quiz on all segments and a team score from it, so experts are rewarded for teaching, not only for presenting	Secondary-school review: STAD most and Jigsaw least successful [~M] (review of 27 secondary studies; the link to missing reward and accountability is the authors' speculation)
Stakes are high (the group grade counts toward a qualification)	Never give every member the same grade for one product; grade the group from individual results, or grade individually and report the group product separately	Free-riding without individual accountability [~M] (school studies; carried to high-stakes settings untested)
Learners are `adult-workplace` teams	Build belonging and shared goals (harmony, a sense of one team) rather than formal role dependence alone; measure what each member can do	Social interdependence, not role interdependence, correlated with performance [~W] (40 brokerage offices, correlational; "social interdependence" there means team belonging, not goal structure)
Some learners expect individual, competitive evaluation, or are low in affiliation motive	Explain how the team score works and why, before the first cycle; let them see that their own score is counted in it; expect less favourable attitudes at first, not lower achievement	High affiliation motive and attitudes to group work [~M] (attitudes differed, achievement did not; online undergraduates); culture untested, from the earlier page

Ten of the twelve rows cite a claim; two are untested proposals that cite a claim only for its scope. Most rows carry a finding to learners or settings it did not test, and say so: the reward evidence is from schools, the interdependence-type experiment from asynchronous online undergraduates, and the workplace row from a correlational study of offices using a different sense of the term.

Observation, state and explanation¶

What can be observed: the task and its division, the roles and resources each member held, how recognition was computed, the talk and posts the group produced (who spoke, to whom, about what), and each member's individual result. "Free-riding", "dominating", "dependent on the fast achiever" and "obliged to contribute" are inferences. A good group product is an observation about the group.

Response	Plausible explanations	Observation that could change the interpretation
Good group product, weak individual check for one member	Freeloading; overspecialisation (the member did a part and never integrated the rest); the member understood in talk but cannot perform alone	Ask the member privately to explain a part they did not produce, and to do a changed item alone; record who did which part.
Members' parts are each correct but do not fit together	The task was divisible into identical pieces; no one held the integrating role; time ran out	Give a task whose answer needs two members' parts combined, and see whether integration talk appears.
Much off-task talk in groups working for a team reward	Reward without a task that needs discussion; reward framed as competition between teams; ordinary social talk	Compare the share of task talk under a role structure on the same task (the online experiment found reward groups most off task and no-structure groups most cognitive talk; interdependence type shifts interactions [~M]).
Members report feeling obliged to contribute, but individual scores do not rise	The structure changed effort or attitude, not understanding; the individual check measures something the group task did not practise	Check alignment of the group task with the individual measure; compare scores on matched and changed items.
A weaker member is resented or excluded	Recognition is normative (rank-based), so a weak member lowers the team score; status differences; the member cannot yet contribute	Switch to improvement-based team scoring and see whether help-giving towards that member changes; probe the member's prerequisite knowledge.

These rows are proposals, untested as diagnostics. A probe is itself a learning event; record it, and keep open the explanations it does not rule out.

Evidence and qualifications¶

In school studies, cooperative and peer-learning methods that reward groups on every member's individual learning raised achievement more than methods without such rewards [+M]: a best-evidence review of 99 school studies of four weeks or more reports a median effect of +.32 for methods whose group rewards rested on each member's individual learning against +.07 for a single group product or no group reward (medians of study results, not pooled estimates); a meta-analysis of elementary peer-assisted learning (d = 0.33 overall) found larger effects with interdependent reward contingencies; a randomised 2×2 study of 64 at-risk 4th and 5th graders found reward plus structured tutoring most accurate in computation. The review also reports structured interaction that works without rewards. Not settled: the entries were read from abstracts. The claim duplicates Cooperative learning without individual accountability produces free-riding [~M] (same three entries), and its Discussion still says it cannot yet carry evidence entries.
Cooperative Learning Improves Achievement [+S]: a meta-analysis of 148 studies of early adolescents associates cooperative goal structures with higher achievement and better peer relationships (direction only; abstract read), and an unpublished report gives weighted d = 0.91 against individualistic and d = 0.70 against competitive conditions for the Learning Together method; about half its studies ran 30 or more sessions. It tests goal structures, not which form of interdependence.
Structuring positive interdependence (role, reward, or both) did not affect posttest achievement for undergraduate business majors in asynchronous online small group work [~M]: 280 undergraduate business majors, blocked by affiliation motive and randomly assigned to role, reward, role-plus-reward or no-interdependence triads; no significant achievement difference (overall about 71% on the posttest; no effect size). This is the limiting claim: a non-significant difference does not show equivalence, but it predicts that adding role or reward structure to online group work need not change achievement. Not yet checked against its source.
Type of interdependence shifts the nature of interactions [~M]: in the same study's transcripts of 40 triads, no-structure groups had the most cognitive interactions, role groups the most group-process interactions and reward groups the most off-task ones; role-plus-reward groups interacted most. It qualifies the model: a structure can raise interaction without raising cognitive talk.
Structured interdependence and the sense of obligation to contribute [+M] and reward interdependence and benefit attitudes [+M]: in the same study, every structured condition agreed more than no structure that teammates' duty to contribute helped them learn, and reward groups agreed more that they benefited and generated better ideas. Self-report (motivation-affect), not achievement.
Small-group learning improves undergraduate STEM achievement [+M]: 39 undergraduate STEM studies, small-group against non-group instruction, weighted d = 0.51. It does not isolate interdependence; the claim page's restriction to structured groups is its own reading, and its Discussion still says the evidence base needs populating.

Learners, settings and outcomes differ (school maths, early adolescents' general achievement, online undergraduates' posttest and attitudes), so do not rank these by effect size. None measures delayed retention.

A discrepancy to note. Several claim pages from Brewer & Klein (2003) describe its participants as adult learners (reward interdependence and benefit attitudes [+M], high affiliation motive [~M]); the evidence entries describe 280 undergraduate business majors and do not say they were adult or reentry students. This page follows the entries.

The evidence by question¶

Which structure matters: group rewards tied to each member's learning, assigned roles, or interdependence of any kind? In school studies, cooperative and peer-learning methods that reward groups on every member's individual learning raised achievement more than methods without such rewards [+M]

Further evidence, not yet read against this model¶

Claims this page cited before it was rewritten, and neighbours found while rewriting it. None is part of the model above.

Worked-example guidance becomes less effective as learner expertise increases. [+S] — cited by the earlier page as an analogy (support should change with learner capability). It is about worked examples in individual study, not interdependence, and does not bear on this page's relationship directly. Its entries are read from abstracts.
Studying worked examples improves novices' algebra performance on problems with the same structure as the examples [~S] — cited by the earlier page as an analogy for structured guidance. It is about studying worked algebra examples individually and does not bear on interdependence. Its entries are read from abstracts or have no source text here.
Science-classroom studies of cooperative learning show mixed results [~W] — second-hand digest of three science studies with null or negative comparisons; it says the expectation can fail in a given implementation, not why.
Cooperative learning has drawbacks including slow learners depending on fast achievers [~W] — an opinion essay (q1, no data); the dependence it names is the freeloading failure mode.
Heterogeneously grouped teams show more benefits than homogeneously formed teams [~W] — a chapter's one-line citation of other research (q1); no study details.
Modes of interdependence are weakly or negligibly intercorrelated across brokerage offices [~W] and the specialisation–role interdependence relationship holds only where colleagues are seen as competing [~W] — the same correlational study of 40 offices; organisational structure, not learning.
Classroom research primarily supports the motivational perspective on cooperative learning effects [+W] — attached 2026-10-14 from Slavin (2014), which proposed "Design cooperative learning with group goals and individual accountability for group success".

Objective and learner-valued goal¶

The designer's objective is usually what each member can do alone at the end of the unit. Elicit separately what each learner wants from the group: a good shared grade, a fair share of the workload, being heard, working with friends, or finishing quickly. A learner who values the shared grade may rationally divide the work, which serves the product and undercuts the individual objective; one who values fairness may resent a weaker teammate under rank-based scoring. Record agreement and divergence as observations, and change the scoring or the task when they conflict.

For example, in an engineering design sprint (from the earlier page), a student may want the team's prototype to score well, while the designer wants each student to be able to justify one trade-off decision. A team prototype score plus each member's short individual justification of a decision they did not personally make serves both, and shows whether the second was met.

What would revise this model?¶

The expectation should weaken if face-to-face groups with team recognition built from individual learning, over several weeks, fail to outperform matched groups with no group reward, or matched individual work, on independent individual measures. If structured interaction without rewards does as well as rewards plus structure, as the review cited suggests it sometimes does, the model should drop group reward from its core and keep role or resource dependence and individual checks. If the online null result recurs in live classrooms, interdependence type is a design preference for participation and attitudes, not for achievement. Do not protect the model by calling every failure "weak interdependence" after the fact; record the structure in advance.

Group product quality, individual achievement at the end of a unit, delayed retention, collaboration skill and attitudes to group work are separate claims. The present evidence sets no group size, composition, duration or scoring rule.

Claims¶

Collaborative Learning
Cooperative Learning — the comparison of structured cooperative work with individualistic and competitive arrangements; this page asks which form of dependence among members to build inside it
Social Learning
Culturally Responsive Classroom Norms — students from cultures emphasizing an interdependent self-concept may find cooperative structures an especially natural fit, while students expecting individual, competitive evaluation may need more explicit orientation to it

Examples¶

In a jigsaw discussion, each learner becomes responsible for one source and the final synthesis depends on every member bringing that expertise back to the group.
In an engineering design sprint, teams submit one shared prototype score plus a short reflection on how each role contributed to tradeoff decisions.
Jigsaw Method — resource interdependence: each member holds one segment the group needs; add an individual check so teaching, not only presenting, is rewarded
Use cooperative group work especially in areas requiring mutual trust, communication, and practice, and direct higher education students to cooperation often
Constructive competition through Social Interdependence Theory — low-stakes Kahoot competition with fair rules and no grade impact in an undergraduate course
