How “Code Trace Studio” works

🎓 You are learning to: Predict, execute and repair small modular programs that use parameters, return values, lists, tables, loops and conditions.

This studio works in three steps:

  1. 📖 Read the challenge

    Understand what the system or program should do before touching it.

  2. 🔮 Predict, then test

    Say what you expect to happen, run it, and compare. Surprises are where the learning is.

  3. 🔧 Debug systematically

    Change one thing at a time and re-test until behaviour matches your prediction.

💡 Aim to explain your method, not just your answer.
