🧩 Quick Study Guide: Debugging in ScratchJr for First Graders
- 🤔 What is a "Bug"? A bug is when your ScratchJr project doesn't work the way you want it to. It's like a tiny mistake in your code!
- 🔍 Debugging is Like Being a Detective: When you debug, you look for clues to find the bug and fix it. You're trying to figure out "why isn't this working?"
- ✅ Check Each Block: Look at each coding block you've used. Are they in the right order? Does each block do what you expect?
- ➡️ Step-by-Step Thinking: Imagine your character doing each step of the code. Does it match what you see on the screen?
- 🔄 Test Often: After you change something, run your project again to see if it fixed the bug or if you made a new one!
- ❌ Common ScratchJr Bugs:
- ⏱️ Wrong Speed: Character moves too fast or too slow (check speed blocks).
- 📏 Wrong Distance: Character doesn't move far enough or moves too far (check move blocks and numbers).
- 🔁 Missing Loop: Character only does something once when it should repeat (check repeat blocks).
- 🚫 Incorrect Start Block: Character doesn't start moving when you tap it or click the green flag (check start blocks like 'on tap' or 'green flag').
- 👻 Character Disappears/Appears Wrong: Check hide/show blocks.
- 💡 Ask for Help: It's okay to ask a grown-up or a friend if you get stuck!
