7. Ethical Use Guide — What's OK vs cheating, university policies, citing AI use
❌ This is cheating (don't do this):
- Having AI write your entire essay or assignment for you
- Using AI on in-class exams or closed-book tests
- Pretending AI-generated work is entirely your own without disclosure
- Copy-pasting AI answers to homework without understanding them
✅ This is ethical use (do this!):
- Brainstorming ideas and creating outlines
- Getting feedback on drafts you wrote yourself
- Explaining difficult concepts you don't understand
- Debugging code you wrote (and learning from the fixes)
- Summarizing research papers to save time
- Creating study tools and practice tests
Key Rules to Follow:
- Check your university's policy first: Every school has different rules — find and read them!
- Cite AI use: If your school allows it, disclose when you used AI tools, just like you cite sources.
- Always understand the final work: If you can't explain what you turned in, you're doing it wrong.
- Use free/student tools: Don't pay for tools you can get free or discounted with your student email.
Remember: AI is a tool to make you a better learner, not a way to skip learning. When used correctly, it can help you understand more deeply and achieve more than you could without it.
