Most teachers track progress using intuition and test scores — too coarse-grained. Knowing a student scored 70% on grammar doesn't reveal whether they struggle with present perfect negatives or article usage with uncountable nouns.
A nano-skill is the smallest measurable unit of language ability: B1.grammar.present_perfect.negative. Each exercise is tagged with 1-3 nano-skills. When a student answers, the system records mastery (0-100) for each.
Three states: Improving ↑, Stable →, Declining ↓. Declining skills trigger targeted review suggestions.
Welcome test determines one of four paths: Comfort (gentle, confidence building), Guided (balanced), Accelerated (fast, gap-focused), Target (exam-focused, intensive).
When creating worksheets, the AI considers declining nano-skills, acquisition threshold skills (80%+), learning path preferences, and student knowledge entries.
Every lesson generates data automatically. Formal review every 8-12 weeks. No separate "test days" needed.
