See Home for a summary and Student Overview for details.

Who can use MoFaCTS?

  • Students
  • Teachers and content creators

Is MoFaCTS free?

The software is open source. Hosting and operations still have infrastructure costs.

  2. Open the learning dashboard.
  3. Choose a lesson and click Start/Continue.

How do I create an account?

Use the sign-up link on the sign-in page when your MoFaCTS site allows public account creation. Some deployments create accounts through instructors, administrators, or experiment links instead.

Submit the sign-up form by choosing Create account or pressing Enter in a form field.

Why do repeated questions appear?

This is expected in adaptive practice. Harder items reappear more frequently until mastery improves.

Can I use speech input?

Yes, if your instance/lesson supports it and browser permissions are granted.

For Teachers and Content Creators

How do I create my first lesson?

Start with Quick Start: Content Creation, then use Content Creation Reference Tables when you need the full field reference.

What is the difference between TDF and stimulus files?

  • TDF defines lesson structure and behavior.
  • Stimulus file contains prompts, answers, and media references.

How do I export student data?

See Data Output.

For Administrators

This section is for site operators, not students. Students should use the student questions above or ask their instructor/site support contact.

What are minimum infrastructure requirements?

See the administrator/deployer lane in the sidebar for deployment and production requirements.

Where is current deployment guidance?

Use the administrator/deployer lane in the sidebar. The canonical pages are Remote Install, Deployment Guide, and Settings.json Reference.

Where does settings.json live in current deployments?

  • Compose mounts the private settings file named by METEOR_SETTINGS_HOST_PATH at /run/mofacts/settings.json.
  • Container startup loads that file through METEOR_SETTINGS_FILE; it is not baked into the image.
  • See the Settings.json Reference and Deployment Guide in the administrator/deployer lane.

Is there a health endpoint for uptime checks?

Yes. Use:

curl -fsS https://your-domain.example.edu/health

See the Deployment Guide in the administrator/deployer lane for monitoring baseline guidance.

How should backups be handled?

Follow the production runbook and schedule recurring DB backups with restore drills.
