Help vs Replace: The Line That Matters

Students get two messages about AI: it will ruin your education, or it is essential to your future. Neither helps at eleven at night with an assignment due.

Here is a more useful frame. Every assignment exists to make your brain do something. The question is whether your brain still did it.

Uses that genuinely build understanding

• Explaining a concept you do not understand, at a level you can follow, with follow-up questions until it clicks
• Quizzing you — one question at a time, with follow-ups on whatever you got wrong
• Checking your own explanation: write it from memory, then ask what is missing or incorrect
• Generating practice problems similar to ones you already struggled with
• Translating a dense passage into plainer language so you can then read the original

Uses that quietly replace the learning

• Generating an essay and editing it — the essay was never the point, the thinking was
• Getting answers to problem sets without attempting them first; the struggle before the answer is what builds the skill
• Summarising readings you never opened — you get conclusions without the reasoning, which is the part being examined
• Producing code you cannot explain line by line

The two-attempt rule

Attempt anything yourself first, properly, before asking. Then use AI to check, correct or explain where you went wrong.

This ordering preserves almost all the learning while removing almost all the stuck time. Reversed, it removes the learning and keeps the illusion of progress.

Know your institution's rules

Policies differ enormously and consequences are serious. Read your own institution's rules rather than assuming from what other students say.

Where a rule is ambiguous, ask before submitting rather than after. An email asking for clarification is a much better position than an explanation afterwards.
