Pro Tips

  • *Provide a shared list of beginner friendly APIs with sample requests and rate limits so students do not hit blockers during class.
  • *Use tiered rubrics where basic credit is for pulling and displaying data, then add stretch goals like charts, alerts, and accessibility checks.
  • *Model safe API key handling with proxy use or school controlled keys and rotate them regularly to protect student work.
  • *Assign roles in pairs, such as data wrangler and interface designer, then switch halfway so every student practices both skills.
  • *Plan offline fallbacks by stubbing a small JSON file so students can continue coding when the API is down or the network is slow.
