For Oppia alternatives, test a lesson that branches based on a learner's answer—not only a static page.
- Recreate a concept explanation, question, feedback, hint, and alternative path.
- Test learner progress, retries, accessibility, and low-bandwidth use.
- Export content, media, and progress data where permitted.
- Check author review, translation, reporting, and privacy controls.
- Ask a learner and educator to complete and assess the pilot.
A learning tool is effective when misconceptions lead to useful feedback. Compare that behavior directly instead of counting templates.
