CompareSpot: a video-club module for noticing peer comparison
A training kit for teachers to help them spot and manage how students compare themselves to their peers.
A three-session professional development kit in which teachers watch short classroom clips, learn to spot the moments students evaluate themselves against peers, and then redesign their own routines — deciding which performance information goes public versus private.
Concept
A facilitator's kit for existing video-club and instructional-coaching formats, delivered as three 90-minute sessions. It contains: a curated set of short classroom clips (or a tagging protocol for clubs using their own footage); a noticing checklist of peer-comparison behaviors — students asking 'what did you get?', glancing at a neighbor's returned paper, reacting to public scores or leaderboards, help-seeking or withdrawal after a comparison; discussion prompts; and a redesign worksheet on which each teacher decides, for one class, which evaluative signals go public (posted distributions, public praise, leaderboards) and which stay private (face-down returns, individual comments). Each teacher leaves with a written comparison-practices plan for one class. The single wedge: teacher training treats students as passive recipients of the teacher's evaluation; this module trains teachers to see the second evaluation channel — peers — that students actively use.
Why now
Paper [0] states that most commentary on classroom evaluation focuses on the teacher as the source of evaluative information, while students actively use peers' performance to evaluate themselves — a documented blind spot in how teachers are trained to read their rooms. Paper [3] shows the delivery format already works: middle-school mathematics teachers met monthly in video clubs where they shared and discussed excerpts of their own classroom video, and a separate group of preservice high-school mathematics and science teachers used video to learn to notice classroom interactions — extending this proven format to a new noticing target (peer comparison) is a low-risk, evidence-based PD product. Paper [1]'s systematic analysis of the teacher's role is the tradition the module updates: the teacher is one evaluator in a room full of them.

AI assessment
A highly focused, evidence-backed PD module that leverages a proven delivery mechanism (video clubs) to address a specific, overlooked psychological blind spot in classroom management.
- Evidence strength 5/5
- The idea directly synthesizes a theoretical gap (peer-comparison as an evaluative source) with a demonstrated delivery method (video clubs for noticing), using specific citations for both.
- Market pull 4/5
- The target beneficiaries are established PD providers and coaching networks with existing budgets for instructional improvement and teacher training.
- Novelty & moat 3/5
- While it shares the 'video club' mechanism with Facilita, it targets a distinct psychological phenomenon (social comparison) rather than a pedagogical method (PBL), filling a gap in 'noticing' training.
- Feasibility 5/5
- The MVP is a low-tech facilitator's kit consisting of clips, checklists, and worksheets, requiring no complex software development.
- Wedge clarity 5/5
- The wedge is exceptionally sharp: moving from 'teacher-as-sole-evaluator' to 'noticing peer-comparison' as a specific professional development goal.
- Simplicity / focus 5/5
- It is a single, three-session module with a clear output (a comparison-practices plan), avoiding any platform bloat.
