Description¶

This strategy pairs two feedback sources: instructor feedback, which carries expert authority and diagnostic depth, and structured peer feedback, in which learners evaluate one another's work against explicit criteria. The combination is not additive but complementary — the instructor models quality judgments, and peers rehearse those judgments on authentic work while receiving more frequent, more timely input than an instructor alone can provide.

Design Implications¶

Feedback is among the most powerful influences on learning, but its effect depends on level and quality: task- and process-level feedback supports improvement, while personal-level praise often does not Feedback is most effective at the task and process levels. [+S]. Peer feedback adds a second mechanism: evaluating a peer's work against criteria is itself a form of Self-Explanation that deepens the reviewer's own understanding Self-explanation improves conceptual understanding. [+M]. The instructor's role shifts from sole commentator to designer of the feedback system — setting criteria, calibrating peer judgments, and intervening where peer input is unreliable.

Context¶

Requirements¶

• Explicit criteria or rubrics so peer reviewers judge the work, not the person
• Training or calibration activities in which students practice evaluating sample work before reviewing peers
• A structure that requires reviewers to explain why something works or fails, not just mark it
• Instructor follow-up that resolves conflicts between peer and expert judgments

Constraints¶

• Untrained peer reviewers default to vague praise ("good job") that produces no actionable guidance [-M]
• Feedback that directs attention to the self rather than the task can depress performance, especially for lower-achieving learners Feedback interventions sometimes reduce performance when they focus attention on the self rather than the task. [-S]
• Peer feedback on complex or highly technical work can be inaccurate; learners may internalize wrong corrections [-M]
• Perceived unfairness or social discomfort in peer review can reduce engagement and trust in the feedback [-W]

Implementation Variability¶

• Sequential: instructor feedback first, then peers revise and review each other's revisions
• Calibrated peer review: students rate sample essays until their judgments align with expert ratings (e.g., Calibrated Peer Review), then review peers
• Dual-channel: peers comment on drafts; instructor delivers the summative judgment, keeping stakes off peer shoulders
• Reciprocal roles: learners alternate between author and reviewer, making the reviewing role itself an assessed activity

Target Learners¶

• Learners in writing-intensive or project-based courses where drafts and revision cycles are natural [+M]
• Large-enrollment settings where instructor feedback volume is the bottleneck; peer feedback multiplies timely input Peer assessment can provide feedback at a volume and timeliness instructors alone cannot match. [+M]
• Learners with enough domain knowledge to make plausible judgments; complete novices may reinforce each other's misconceptions [~M]

Target Learning Goals¶

• Quality judgment: internalizing criteria for what makes work good (evaluative knowledge)
• Revision and iteration: using feedback to improve drafts or products
• Metacognition: comparing one's own work against external standards Self-monitoring improves self-regulation. [+M]

Instructions¶

1. Define explicit criteria and share a rubric with worked examples of strong and weak work (Non-Examples).
2. Run a calibration round: students evaluate anonymized samples and compare their judgments to instructor ratings; discuss discrepancies (Coaching).
3. Have students exchange drafts and give criterion-referenced comments that must include a reason and a suggestion.
4. Deliver instructor feedback on the same drafts, modeling the diagnostic depth you want peers to approximate.
5. Require revision in response to feedback, and have authors briefly note which comments they acted on and why (Assessment for learning, not just of it).

Related Strategies¶

• Formative Assessment — feedback is the mechanism that makes formative assessment work
• Collaborative Learning — peer feedback structures collaboration around authentic work products
• Self-Assessment — the evaluative skills built by peer review transfer to judging one's own work
• Peer-delivered prompts in which students take over prompting, feedback, and assessment from an instructor

Examples¶

• Calibrated Peer Review (CPR) (https://calibratedpeerreview.org) — a web system in which students first review calibration documents with known instructor ratings, then review peers' work; used widely in undergraduate chemistry and writing courses.
• Peergrade / PeerStudio-style workflows in MOOCs — platforms such as Coursera route assignments through structured peer review with rubrics when instructor grading is infeasible at scale.
• Writing-across-the-curriculum programs (e.g., Michigan State's peer writing consultant model) pair instructor comments on drafts with trained peer consultant sessions before revision.
