Is AI hurting student writing? What the calculator and mental math comparison tells parents and teachers
Last Wednesday, I stacked rough drafts of 10th grade personal narratives on my classroom desk, the left corner crinkled from a spilled iced coffee that morning, and pulled out Javi’s. Javi’s the kid who skateboards to school, leaves orange spray paint smudges on the back row desk, and always stops after class to tell me about the new trick he’s been working on. His writing is usually messy, funny, and full of asides about his annoying little sister and the run-down skate park on the west side of town. This draft was different: perfectly structured, grammatically flawless, and totally generic. It talked about “learning the value of persistence” through skating, with no mention of the broken wrist he’d hidden from his mom for two days last fall, the story he’d rambled about to me before first bell. When I called him over, he scuffed the toe of his white Vans on the tile and admitted he’d plugged three bullet points into AI to “make it sound good enough” for a good grade.
That conversation got me thinking about a chat I had a few weeks prior with my old 7th grade math teacher, Ms. Henderson, when I ran into her at the grocery store. We got to talking about all the AI panic in education, and she laughed and said she remembered when administrators and parents were screaming about graphing calculators destroying kids’ ability to do math. Back in the 1990s, everyone swore kids would never learn to add or divide if they let a machine do the work for them. “Now look,” she said, loading Honeycrisps into her canvas bag. “I still can’t do long division of a three-digit number in my head to save my life, and I turned out fine. The thing everyone missed back then was that the calculator didn’t get rid of the need to think — it just got rid of the tedious part, so we could teach more thinking.”
Is AI doing the exact same thing to student writing? And does all the panic even make sense?
A few years back, before AI became ubiquitous, I spent three weeks of every semester drilling kids on how to write a proper five-paragraph structure, how to craft smooth transitions, how to write a hook that grabs the reader. Half the kids checked out halfway through, because they were so focused on getting the structure right that they forgot what they wanted to say in the first place. Now, I don’t do that anymore. I start every writing assignment with a 3-minute voice note, due before any formal writing happens. Kids can ramble, stutter, go off-topic, whatever — it just has to be their voice, talking about what they actually think or what actually happened to them. That takes 5 minutes out of class, and it gives me a clear record of what the kid actually wants to say before any tool gets involved.
For Javi, after he admitted he’d used AI to draft, I didn’t accuse him of cheating or make him start over. I told him to pull up that voice note he’d recorded, pull up the AI draft side by side, and go line by line. Anywhere the AI said something that wasn’t what he actually said, he had to change it. His job wasn’t to write it from scratch — it was to make it sound like him.
This approach translates just as well to parents at home. If your kid is working on a writing assignment and you suspect they used AI to draft, you don’t have to snoop through their browsing history or start a fight about cheating. Instead, ask three specific questions: “Show me one sentence in here that only you would write.” “If you were telling this to your best friend, what would you add that’s not here?” “Does this actually say what you think, or does it just sound right?” That’s low-friction, it doesn’t assume the worst, and it pushes kids to practice the skill that actually matters.
Of course, it’s not an exact 1:1 comparison. There’s a real difference between mental math and writing. Mental math is a tool for getting an answer. Writing is how we figure out what we think in the first place. If you never practice putting your own messy, unpolished thoughts into words, you lose the ability to clarify what you actually believe, what you actually care about. That’s the part that matters — it’s not that kids are cheating, it’s that the thinking work of writing can’t be outsourced, because that work is the whole point.
But just like with calculators, we don’t have to throw the tool away entirely. Ms. Henderson told me that after calculators became standard, she stopped spending three weeks on long division drills, and started spending that time teaching kids how to check if their calculator answer makes sense. If you plug 150 divided by 10 into your calculator and get 1500, you don’t need to do the whole problem by hand to know that’s wrong. You just need to understand what the answer should look like.
That’s exactly what we’re doing with writing now. AI is the calculator. It does the tedious work of turning bullet points into structured sentences, of fixing grammar, of drafting a transition that’s not awkward. The skill we need to teach kids now is how to tell if the final product makes sense, if it sounds like them, if it says what they actually want it to say.
Last week, Javi turned in his final draft. He kept the AI’s opening paragraph, but cut the generic line about “persistence” and added the part about hiding his broken wrist under a hoodie for two days, scared his mom would ban him from skating. He ended it with a line I’ll probably keep for years: “Landing the trick felt cool, but admitting I broke my wrist felt even cooler. Turns out I don’t need a trick to be good at something.” It was the best personal narrative I’d read all semester. Way better than anything he would have written if he’d spent three hours stressing about getting the structure right.
I still don’t have all the answers. Last night I graded a paper that was 100% AI, no changes, no voice, just generic points about To Kill a Mockingbird that you could find anywhere. I didn’t fail the kid — I wrote back “This is good, but I don’t hear you. Tell me what you actually thought of Atticus, and we’ll try again.” Some days I worry we’re letting too much basic skill slip, that kids won’t know how to write a paragraph from scratch when they need to. Just like those teachers 30 years ago worried we’d never be able to calculate a tip at a restaurant. I still can’t do long division in my head, but I can spot a wrong answer when I see one. And that’s what matters. Right now, that feels like enough.
