Adaptivity Grid Audit for Learning Products
An audit that tells learning app developers which adaptive features actually improve student results.
An audit service that maps a learning app's adaptive features onto a research-backed 15-form taxonomy of adaptivity, flags which of its features have experimental evidence behind them, and hands the product team a ranked list of the highest learning-gain-per-effort adaptations to build next.
Concept
A focused audit offering for learning-technology product teams. The team submits its product's adaptive behaviors (via a structured questionnaire plus a sandbox review), and each behavior is mapped onto the Adaptivity Grid — the taxonomy distinguishing 15 forms of adaptivity across step-, task-, and design-loop levels introduced in the new review. The deliverable has three parts: (1) a coverage map showing which of the 15 forms the product implements and which it does not; (2) an evidence flag for each implemented form, since the review found experimental support for only 12 of the 15; and (3) a build roadmap ranked by the review's "bang for the buck" finding — step-loop adaptation to student strategies and errors, design-loop adaptivity generally, and task-loop adaptation to student knowledge — using the review's tables of concrete, empirically supported adaptations as the implementation specs. The single wedge: replace intuition-driven decisions about which adaptive features to build next with an evidence-ranked gap analysis.
Why now
The new review [0] is the first to organize the adaptivity evidence with a fine-grained 15-form taxonomy, isolate which specific forms have experimental support (12 of 15), and explicitly rank forms by learning gains relative to implementation effort — naming step-loop adaptation to student strategies and errors, design-loop adaptivity, and task-loop knowledge adaptation as the best value. It also supplies tables of concrete adaptations with empirical support. That is precisely the raw material an audit rubric needs, and it did not previously exist in a consolidated, decision-ready form — the review itself frames its goal as moving toward "an engineering practice of adaptive instruction grounded in empirical research."

AI assessment
A high-utility, low-risk consulting wedge that transforms a complex academic taxonomy into a pragmatic product roadmap for EdTech companies.
- Evidence strength 5/5
- The idea directly operationalizes the specific 15-form taxonomy and 'bang for the buck' rankings provided in the research text.
- Market pull 4/5
- Major EdTech players (Khan, IXL) face immense pressure to prove efficacy to institutional buyers, making an evidence-based audit highly attractive.
- Novelty & moat 4/5
- While other ideas focus on building specific adaptive tools, this is a meta-service for product strategy, filling a gap in the catalog.
- Feasibility 5/5
- The MVP is essentially a structured rubric and a consulting engagement; it requires no complex software development to launch.
- Wedge clarity 5/5
- The 'gap analysis' is a sharp, specific entry point that provides immediate value before potentially expanding into implementation services.
- Simplicity / focus 5/5
- The product is a single, focused audit service with a clear deliverable, avoiding the 'platform' trap.

Who benefits
- Carnegie Learningcompany
Its MATHia platform is built on adaptive tutoring; an audit would show which of the 15 adaptivity forms its engine actually covers and which high bang-for-buck forms (e.g., design-loop adaptivity) are missing, directly informing its roadmap.
- IXL Learningcompany
Runs one of the most widely used adaptive practice products; the audit replaces intuition-driven feature prioritization with an evidence-ranked backlog of supported adaptations.
- Khan Academyorganization
A nonprofit with constrained engineering resources; the review's bang-for-the-buck ranking tells it exactly where limited development effort buys the most learning gain.
- Owl Venturescompany
An edtech-focused investor that can use the audit in diligence to check whether a target's 'adaptive learning' claims map to empirically supported forms of adaptivity.
