Is AI Hurting Student Writing? What The Calculator-Mental Math Parallel Tells Parents and Teachers
I was grading 8th grade personal narrative drafts last month, the classroom still smelling like cheddar Goldfish from Friday’s class party, my third cup of coffee gone lukewarm, when Mia knocked on the half-open door. She twisted the strap of her canvas backpack back and forth, the one covered in K-pop stickers, and asked if she could talk. She was applying for a pre-college summer program for public health, and she’d spent three days stuck on her admission essay. Finally, she’d plugged her prompt into ChatGPT, got a full draft back in 10 seconds, and hated every word of it. “It sounds like a grown-up wrote it,” she said. “It doesn’t sound like me. Is that cheating?”
That weekend I went to my dad’s house for dinner, and the whole conversation clicked into place. Dad was a high school math teacher in the 1990s, and he spent half of 1996 fighting the school board’s decision to allow graphing calculators on the AP Calculus exam. I remembered sitting at his kitchen table after school, forced to do long division by hand even though my algebra textbook said I could use a calculator. “Kids these days won’t be able to calculate a 15% tip without a machine,” he’d grumble.
That phrase popped into my head the second Mia finished talking. Everyone’s panicking about AI and student writing right now, and it sounds exactly like that old calculator panic: Is AI doing the same thing to student writing that calculators did to mental math? And if it is, does that actually matter?
Thirty years later, we know how that calculator story turned out. I can still calculate a 15% tip in my head, thanks to all that practice at my dad’s kitchen table. I just don’t usually bother— I pull out my phone if I’m splitting a bill with four people. Calculators didn’t eliminate mental math, they changed what we use it for. We stopped wasting time on repetitive computation that a machine could do faster, and started focusing on what humans actually need to be good at: problem solving, checking if an answer makes sense, applying math to real life.
That’s exactly where we’re at with AI and writing. Mia’s AI draft talked about how she learned patience helping her grandma tend her rose garden, a generic sweet story that could have belonged to any kid. What it missed was the messy, specific truth: Mia hates pulling weeds. She goes over every Sunday because her grandma’s knees are too bad to do it herself, and after they’re done, they bake lemon bars that are almost always overcooked because grandma forgets to set the timer. The AI didn’t mention the lemon bars. It didn’t mention that Mia wants to study public health because grandma can’t afford a home health aide, and she’s watched her have to choose between groceries and physical therapy. All that stuff was too specific, too messy, too hers for AI to pull out of the collective internet.
I don’t ban AI in my classroom, the same way most math teachers don’t ban calculators anymore. But I have rules that are pretty similar to the rules my dad had for calculators when I was a kid: you don’t get to use it until you can do the work yourself first. For a 6th grader working on their first five-paragraph essay about their favorite book, that means no AI. They need to practice picking a thesis, organizing their paragraphs, writing an introduction and conclusion on their own first, just like a 2nd grader needs to practice their addition facts before they get to use a calculator.
For older kids working on college essays or research papers, we use AI as a first draft tool, just like I use a calculator to add up my grocery bill. The concrete exercise I teach them is simple: after you get the AI draft, cross out anything that doesn’t sound like you, then add at least three specific personal details or observations that AI didn’t include. For parents checking in on homework at night, instead of asking “did you use AI?” you can ask “what three things did you change or add after that first draft?” It shifts the conversation from cheating to thinking, which is what we actually care about.
Last semester, I had a 9th grade boy named Javi who used AI to write a draft arguing that middle schools should fund varsity soccer instead of just club soccer. The AI draft was full of generic lines about teamwork and physical health, the kind of thing you’ve read a hundred times. Javi went in, cut all that, and added the part about his asthma, how playing soccer helped him learn to control his breathing when he had an attack, how he couldn’t afford club fees so when they cut the middle school team last year, he couldn’t play anymore. That essay didn’t just get an A from me. He presented it to the school board, and they reinstated the team this year. He never would have gotten there that fast if he’d spent two weeks stuck on a generic first draft, but the work that mattered— the work that made a difference— was all his.
I’m not saying there’s nothing to worry about. There are still plenty of kids who turn in the full AI draft without changing a word, just like there are still kids who rely on calculators so much they can’t estimate if a 20% off sale is actually a good deal. The key is that the skill we need to teach isn’t “how to write a draft from scratch without any help” anymore, just like the key math skill isn’t “do long division by hand.” It’s “how to tell when a piece of writing is good, how to make it yours, how to fix what’s wrong with it.” That’s the part AI can’t do, and that’s the part that matters.
Mia got her acceptance to that summer program a couple of weeks ago. She brought me a lemon bar, slightly burnt, just like the ones she wrote about. Last week, I got lunch with my dad, and when the bill came, I reached for my phone to split it with him. He laughed and said, “I knew you’d turn out to be a calculator cheater.” I told him about Mia and her essay, and the AI comparison. He thought for a minute, and said, “I still think kids should practice the basics. But I guess I was wrong about calculators being the end of math as we know it.”
We still don’t know exactly how AI will change writing for the next generation. I don’t have all the answers. But right now, what’s working is this: teach the basics first, let the machine do the boring grunt work, and make sure kids know the only writing that matters is the part that sounds like them. That’s enough, for now.
