If a task can be completed by pasting the question into a chatbot, some pupils will do exactly that. Rather than policing it, the sustainable answer is designing homework where AI doesn't bypass the learning.
Why detection and banning don't work
Detection is unreliable — see the honest position on AI detectors. And banning teaches concealment rather than judgement. Meanwhile the tools are on every phone. Designing better tasks is the only approach that actually holds.
Task types that resist AI
1. Anchored to your specific lesson
"Using the three examples we discussed on Tuesday and the diagram in your book, explain..." AI doesn't know what happened in your classroom. This is the single easiest change and it works immediately.
2. Personal response and local context
Work requiring the pupil's own experience, their own community, their own data. AI can fabricate this, but it produces generic answers that stand out sharply.
3. Process, not just product
Ask for the plan, the rough draft, the crossings-out and the reflection. Assess the journey. A pupil who generated the final answer has nothing to show.
4. Physical and practical
Measure something, build something, interview someone, photograph something. Simple and effective, particularly at KS3.
5. In-class writing on prepared work
Research at home, write in class. Keeps the preparation meaningful and the assessed writing genuinely theirs.
6. Critique and improve AI output
Give pupils an AI-generated answer with errors and ask them to find and correct them. This is harder than writing it themselves, teaches evaluation, and turns the tool into the object of study.
Prompt — generating a flawed answer to critique
Write a Year 8 answer to this question that sounds confident but contains three specific factual errors and one weak piece of reasoning. Don't mark them — I want pupils to find them. Give me the list of errors separately.
Reframing rather than resisting
Some of the best KS3 homework now assumes AI use openly: "Use AI to generate three explanations of this concept, then decide which is best and justify why." The pupil must understand the content to judge the output — the learning is preserved and something useful about AI literacy is added. See teaching AI evaluation skills.
The honest question to ask of any task: if a pupil completed this with AI in ten seconds, would they have missed the learning? If yes, redesign it. If no — if the task was busywork the learning didn't depend on — that's worth knowing too.
Be realistic about workload
Redesigning every task at once isn't feasible. Start with the homework that matters most — the extended written tasks, the ones that feed into assessment — and leave the low-stakes recall work alone; retrieval quizzes are largely AI-proof anyway because the point is the pupil's own recall. See retrieval practice with AI.
Tell pupils what the rules are
Much apparent cheating is genuine confusion about what's allowed. Be explicit, task by task, whether AI use is permitted, and what pupils must declare. Clear expectations prevent most problems.
Need a consistent whole-school approach to pupil AI use?
We help schools set expectations staff and pupils understand. AskColin gives schools low-cost monthly support with one-to-one help whenever you need it — so when you're stuck on a real job at 8am, there's someone to ask. Practical, jargon-free, built around your department.

How do you design homework that AI can't do?
Anchor tasks to your specific lesson, require personal or local context, assess process rather than just product, use physical and practical tasks, do research at home and writing in class, and set tasks where pupils critique and improve AI output.
Why doesn't banning AI for homework work?
Detection is unreliable, banning teaches concealment rather than judgement, and the tools are on every pupil's phone. Designing tasks where AI doesn't bypass the learning is the only approach that holds sustainably.
What's a good AI-aware homework task?
Ask pupils to use AI to generate several explanations of a concept, then decide which is best and justify why. The pupil must understand the content to judge the output, so learning is preserved while adding genuine AI literacy.
Should all homework be redesigned for AI?
No — that's not feasible. Start with tasks that matter most, particularly extended written work feeding into assessment. Low-stakes retrieval quizzes are largely AI-proof anyway, since the point is the pupil's own recall.
