AI in the classroom: a 45-minute debate lesson
A ready-to-run debate on whether students should be allowed to use AI writing tools for homework. Students take a side, argue it, then have to argue the opposite, which is where the real language work happens.

This one runs itself, because every student in the room already has an opinion and most of them have already done the thing being debated.
Level: high school, upper intermediate and above. Forty-five minutes. No printing required beyond the handout, and you can run it from the board if you have none.
The motion
Students should be allowed to use AI writing tools for homework.
Keep it exactly that wide. Narrower motions ("for essays only", "with a citation") produce better arguments but weaker participation, and participation is what you want first.
Timing
| Minutes | What happens |
|---|---|
| 0-5 | Put the motion up. Hands: agree, disagree, unsure. Count them on the board. |
| 5-12 | Split into two groups by side. Unsure students go to the smaller group. Prepare three arguments. |
| 12-24 | Debate. Two minutes each side, then one minute each for rebuttal. |
| 24-32 | Swap sides. Same students, opposite position, three new arguments. |
| 32-40 | Second round of debate. |
| 40-45 | Vote again. Compare with the first count. Ask who changed and why. |
The swap at minute 24 is the whole lesson. Arguing a position you do not hold forces students off memorised phrases and into actual construction.
Arguments they will reach for, and what to do with them
"It is cheating." Push back with a question: is a spellchecker cheating, is a calculator cheating in maths. Make them draw the line somewhere and defend where they drew it.
"It saves time." Ask what the time is being saved for. If the answer is "more study", follow it. If the answer is "games", that is honest and also an argument the other side can use.
"We will not learn to write." Strongest argument on that side. Give them the language for it: rely on, lose the skill, in the long run.
"Everyone will use it anyway." Common, and weak as an argument. Teach them why: it describes what happens, not what should happen. That distinction is worth five minutes on its own.
Sentence frames to put on the board
- I agree with the motion because ______.
- The main problem with that is ______.
- That may be true, but ______.
- If we allow this, then ______.
- In the long run, ______.
Insist on the frames in round one. Drop them in round two and see what survives.
What we would change if the class is quiet
Run the preparation in pairs rather than groups, and have each pair deliver exactly one argument. A quiet class will let two confident students carry a group debate; pairs stop that.
If a class is very quiet, skip the open debate and run it as a written exchange: each pair writes an argument, passes it to the opposite pair, who must write a rebuttal. Same thinking, less exposure.
