Why Can’t My Teen Focus on Long Articles? A Teacher on School AI Blocks and Shrinking Attention Spans
Last period on a rainy Tuesday, my half-drunk iced matcha was sweating through its napkin next to a stack of printed personal essays on the front desk of my 10th grade English class. It was 1200 words, four double-spaced pages, a quiet story about a first-gen student touring colleges with her mom, who cleaned office buildings overnight. Our school’s Wi-Fi had blocked all generative AI tools two weeks earlier, admin’s call after plagiarism reports jumped 40% first semester. I was halfway through reminding everyone to grab a pen and mark lines that stood out when Javi, who sits in the back row and usually turns in solid work without a fuss, leaned back in his chair and huffed. “I can’t do this,” he said. “My attention span’s too short for articles this long.”
A couple kids nodded. Mia, who sits up front and always has her notebook color-coded, flipped the packet back and forth like the pages might somehow shrink if she moved them fast enough. “Me too,” she said. “I tried the first paragraph three times for homework last night and I couldn’t tell you what it said after.”
Before the block, I’d assigned this exact same essay to last semester’s class as a digital homework task. Back then, every kid had the link pulled up on their school-issued Chromebook, and I knew exactly what most of them did after I finished giving instructions: copied the URL, pasted it into the unblocked chatbot, typed “summarize this and answer the three discussion questions,” and hit enter. Ten minutes later, they’d submit their responses and spend the rest of the period scrolling short-form video on their phones or playing browser games. When I graded those, 80% of the responses were nearly identical. No one mentioned the line about the mom keeping a crumpled college brochure in her cleaning caddy for 10 years. No one connected it to their own family’s work. Everyone got the three main plot points right, and almost no one actually read the piece.
I’d spent the first two weeks after the block grading messier, more original discussion responses—more wrong takes, more weird personal asides, far fewer perfectly polished paragraphs—and dealing with a handful of kids who’d tried to access AI on their cellular data and gotten detention, but I hadn’t stopped to notice how many kids were just… stuck on the reading itself. I didn’t connect the dots until Javi said that out loud in class.
After the bell rang, Javi stayed behind, leaning against the doorframe like he didn’t want anyone else to overhear. He said he wasn’t trying to get out of work. He’d tried reading the history textbook chapter the night before, too, and kept catching himself reaching for his phone to look up a summary before he’d finished a single section. Before AI was blocked, he told me, he didn’t even think about it. He’d paste the link, get the answers, pass the quiz, and never had to fight that fuzzy, itchy feeling when his brain started to drift two paragraphs in. He thought he was the only one. He’d spent months thinking he just had a bad attention span, some personal flaw he had to work around with tools.
That’s the connection, I think, though it’s not the hot-take argument most people land on when they debate AI in schools. Blocking AI didn’t shrink these kids’ attention spans. It just exposed how much AI was letting them skip the slow, repetitive work of building attention stamina in the first place.
Attention for long-form reading isn’t a trait you’re born with, after all. It’s a muscle. You build it by sitting through the boring parts, by re-reading a paragraph three times when you zone out, by waiting for the payoff instead of getting an answer 10 seconds after you feel confused. When I was in high school, if I didn’t want to read a chapter, I could skip it and guess on the quiz, or dig up a dog-eared CliffsNotes at the public library, but that took effort. Most of the time, I just slogged through, because there was nothing easier to reach for. Now, every hard or boring moment has an immediate out. Short-form videos train you to get a new punchline every 15 seconds. Group chats ping every two minutes. AI was just the final piece: it didn’t just distract you from reading, it did the reading for you, so you never had to push past that first flicker of boredom.
That day in class, after Javi and Mia spoke up, I scrapped my original 25-minute silent reading plan. I told everyone to tuck their phones in the hanging pocket chart by the door—we’ve had it all year, but I rarely enforced it—and only read the first page and a half. Seven minutes, I said. Pen in hand, just circle one line that reminds you of something your family does. When the timer goes off, we’ll turn to the person next to us and talk about that line for three minutes. Then we’ll do the next chunk.
No one complained. Half the class found a line they wanted to talk about, and when we moved to the second chunk, only two kids tried to sneak phones out before the timer went off. I didn’t give them detention. I just walked over and tapped the edge of their desk, and they put them away. It’s not defiance, most of the time. It’s a habit as automatic as reaching for a seatbelt when you get in a car.
I’ve passed this same trick along to half a dozen parents who’ve emailed me in the last month, worried their kid can’t focus on homework anymore. It doesn’t require taking phones away entirely or installing expensive monitoring software, which almost always just starts fights no one wins. The script I suggest is simple: instead of arguing about screen time for an hour, say “Let’s do 10 minutes of focused reading first, phone on the kitchen counter, then you get a five-minute break with it, and we’ll do another 10.” Chunking the work takes the pressure off the idea that they have to sit focused for 45 straight minutes, which most adults can’t even pull off these days. One mom told me at conferences last week she started sitting at the kitchen table with her own physical magazine during those 10 minutes, instead of scrolling work email next to him, and their homework fights dropped by about half. Kids copy what they see, not what you tell them to do.
I don’t buy the line that all AI has to be banned forever, either. I still tell kids if they’ve read the whole article or chapter and want to use AI on their own data to walk through a confusing part or check if they missed a key point, that’s no different than me using CliffsNotes to get through Wuthering Heights in 12th grade. The problem comes when the tool comes first, before you’ve even tried to work through the text on your own. You can’t build muscle if someone else lifts all the weights for you.
Last week, we finished that college essay unit, and Javi wrote his own personal essay about his mom’s house cleaning business, wove in that line about the brochure in the cleaning caddy without me prompting him. It was one of the strongest pieces I’ve graded all year. But that doesn’t mean everything is fixed. Last week I assigned a 15-page short story for homework, broken into three 10-minute chunks with check-in questions posted online, and almost half the class didn’t finish. Plenty of kids still reach for their phones the second they hit a sentence they don’t understand. The school board is already debating rolling the block back next year, saying kids need to learn to use AI for college and jobs, and I don’t know how that vote will go.
What I do know is that comment from Javi didn’t come out of nowhere, and it wasn’t caused by a Wi-Fi filter. The filter just let all of us see what had been hidden for a long time: most kids don’t get to practice paying attention slowly anymore, one paragraph at a time. We’re all still figuring out how to give that space back, seven minutes at a time.
