DeliveryCheck: a transmission-assumption linter for lesson plans
A teacher or instructional designer pastes a lesson plan or slide deck and gets back every segment that assumes knowledge transfers by telling — plus a concrete constructive reframe for each — so materials stop being engineered for delivery when learning is construction.
Concept
[0]'s opening describes the default state of the profession: educators 'were concerned with getting knowledge into the heads of their students,' with 'no doubt at all' that knowledge could be transferred. The paper's counter-thesis — learning is a constructive activity — implies the installed base of lesson materials is systematically misengineered: objectives like 'students will understand X,' definitions-first sequences, and explain-then-practice structures all presuppose a transfer the paper shows to be untenable.
DeliveryCheck is a linter, in the software sense. It reads a lesson plan (text, document, or slide outline) and returns an annotated copy. It flags each transmission-shaped move — telling before doing, single-answer recall objectives, worked examples followed by identical practice — computes a simple delivery/construction ratio for the plan, and for each flag proposes one reframe pattern, e.g., 'show three worked examples, two of which quietly follow different rules, and ask students to state the rule they think is operating,' so the student builds the idea before hearing it named. The output is a one-page rewrite plus the ratio, so a department or publisher can track whether its plans are actually changing. The wedge is deliberately narrow: it audits the plan, not the teacher, and prescribes patterns, not philosophy.
Why now
[0] demonstrates that the transmission premise organized not just individual lessons but the whole research-and-testing apparatus — criterion-referenced tests and statistical optimization of delivery — so the stock of material built on it is vast and homogeneous, which is what makes a mechanical, pattern-based audit feasible and useful now. [2] shows the teacher's role is defined across classroom, school, and society and is encoded in the plans teachers write, so a plan-level audit reaches the role itself rather than a single lesson. [5] supplies the constructive reframe tradition — learning through experience in a democratic society — that the suggested patterns operationalize. [1] provides the developmental check that reframes must match the learner's stage rather than assuming a generic student.

AI assessment
A focused, high-utility audit tool for curriculum publishers that converts passive 'delivery' lesson plans into active 'constructive' learning experiences.
- Evidence strength 4/5
- The idea is strongly grounded in the theoretical shift from transmission to construction described in the provided texts, specifically operationalizing the critique in [4].
- Market pull 4/5
- Curriculum publishers and teacher-prep programs have high incentives to modernize materials to meet current pedagogical standards and 'evidence-based' mandates.
- Novelty & moat 4/5
- While other tools audit representation or differentiation, this specifically targets the 'transmission vs. construction' structural logic of a lesson, filling a distinct gap.
- Feasibility 5/5
- With modern LLMs, creating a linter that identifies specific linguistic patterns (e.g., 'teacher will explain') and suggests reframes is a straightforward implementation.
- Wedge clarity 5/5
- The wedge is exceptionally sharp: it is a 'linter' for documents, avoiding the complexity of classroom management or real-time teacher coaching.
- Simplicity / focus 5/5
- The product is a single-purpose tool with one clear input (lesson plan) and one clear output (annotated audit), avoiding platform creep.
