NEXORA — Classroom Engagement Intelligence
NEXORA analyzes student engagement during lessons from videos and annotations (human or generated), and reports it to teachers, school leadership and parents as metrics, timelines, reports and action plans.
This documentation is tester-oriented: it describes the platform exactly as it exists in the code, page by page, with the meaning and exact computation of every metric, the full UX flows and the deployment.
The 4 pillars of the platform
| Pillar | Role | Page |
|---|---|---|
| 🎥 Acquisition | Lesson video → observation windows | Architecture |
| 📝 Annotation | 7 categories A–G, coded labels, 15 s windows | Taxonomy |
| 🧮 Scoring | 0–10 score per category → window → engagement levels | Metrics |
| 📊 Restitution | Dashboard, history, stats, messages, follow-up, parent portal | Features |
