Prioritize learning gains, completion quality, and timely feedback rather than mere attendance. Use pre-post assessments, spaced retrieval checks, and rubric-aligned peer reviews. Normalize against baseline differences to avoid penalizing ambitious goals. When collecting sensitive outcomes, aggregate and anonymize results to keep individuals safe while guiding improvements.
Run A/B tests on scoring weights, diversity boosts, and onboarding prompts. Consider contextual bandits for adaptive policies that respect constraints. Guard against interference between pairs by using cluster-level designs. Publish experiment charters up front, and debrief afterward, turning every test into shared learning, not secret tinkering.
