The gap
Practice platforms can count correct answers, but often cannot show why a misconception persists or whether a learner can transfer an idea.
Evidence before scale
A product thesis built to be tested.
Lattice begins with a narrow curriculum, a clear learning hypothesis, and measures that distinguish real reasoning growth from faster task completion.
Stage: concept prototypeInitial wedge: IGCSE PhysicsBuyer: international schools
The opportunity
Schools have content. The missing layer is reasoning visibility.
The wedge
Physics offers explicit models, rich representations, and testable claims—an unusually strong domain for developing a reasoning engine.
The expansion
Once validated, the underlying reasoning patterns can support mathematics, science, humanities, and interdisciplinary inquiry.
Proposed pilot
Twelve weeks. Three questions.
The figures below are study targets for a future pilot, not company results.
Does reasoning transfer?
Compare performance on unfamiliar problems before and after six curriculum units.
Target signal≥15% improvement over regular practiceDoes independence grow?
Track hint use alongside explanation quality and delayed retention.
Target signalFewer hints without lower accuracyDo teachers act sooner?
Measure whether class-pattern summaries lead to useful lesson changes.
Target signalOne actionable intervention per weekProduct path

Illustrative economics
£12–18per student / monthPricing hypothesis for a supported school pilot; not a current offer.
Known risks
The hard questions belong on the roadmap.
Hallucinated feedback
Constrain generation with reviewed content, verifiable solution paths, and teacher escalation.
Over-inference
Keep learner signals provisional, show source evidence, and avoid personality or ability labels.
Teacher workload
Measure whether new insight saves planning time rather than creating another dashboard to manage.
Equity of access
Design for school deployment, low-bandwidth use, and shared-device settings from the beginning.
