A few weeks ago I was walking past a classroom and I heard something that stopped me in the doorway. A student was reading an AI-generated paragraph out loud to her partner. Not to check it, or question it, or build on it. Just to submit it. Her partner nodded. They moved on.
Neither of them looked uncomfortable. That’s the part that got me.
We’re past the phase where AI in schools felt strange or exciting or vaguely dangerous. For a lot of students, it’s just the way things work now. And that shift — from novelty to habit — is happening faster than most of us are prepared for.
The Year Habits Harden
If you’ve been following the research, you’ve probably seen the numbers. Nearly 9 in 10 students used AI in the last school year. About 3 in 10 teachers use it weekly. The global AI education market hit $7.5 billion in 2025 and is projected to pass $112 billion by 2034.
Those numbers are interesting, but they’re not the story. The story is what’s happening underneath them.
2026 is the year habits harden. The policies, tools, and norms we choose now will set the defaults for how a generation learns, works, and thinks with AI.
That’s not my line — it’s from a Fordham Institute analysis published earlier this year. But it’s the most honest framing I’ve read about where we are. The panic-and-pilot years are over. What’s being built right now is routine.
And here’s the uncomfortable truth: routines get built whether teachers are involved in shaping them or not.
The Critical Thinking Problem Is Real
Something is happening to how students think, and we shouldn’t look away from it. According to a recent RAND study, the majority of middle and high school students say they’re worried that using AI for schoolwork is eroding their critical thinking skills. Nearly 70%.
Students are telling us something. They feel it happening and they’re naming it. 66% of secondary teachers report observing pupils losing their capacity for independent thought as AI becomes more embedded in daily learning.
I want to be careful here. This isn’t an argument against AI in education. I genuinely believe these tools can make teaching better. What I’m describing isn’t a reason to retreat — it’s a reason to be more intentional.
The student I saw in that hallway wasn’t doing something wrong, exactly. She was doing something efficient. The problem is that efficiency and learning are not the same thing, and we haven’t been clear enough with students about the difference.
What Actually Works
The research is getting clearer on this. AI used as a research partner — something to interrogate, push back on, and build from — can actually strengthen critical thinking. AI used as a shortcut to the finish line does the opposite.
The variable isn’t the tool. It’s the task design.
When we build assignments where the thinking is in the middle — not just in the final product — AI becomes something students have to wrestle with rather than defer to. That’s a meaningful distinction.
A few things that have been working in my classroom and in the classrooms of teachers I talk to regularly:
- Asking students to argue against the AI’s answer before they can use it
- Building “decision moments” into tasks where students have to make a judgment call that the AI can’t make for them
- Using AI output as a first draft that students must visibly disagree with in at least two places
- Requiring students to explain their prompts — what they asked for, why, and what they changed
None of these are radical. They’re just designs that put the cognitive load back on the student.
The Takeaway: One Change You Can Make This Week
Before your next writing or research assignment, add one requirement: students must identify one place where the AI was wrong, incomplete, or missing something important — and fix it.
That’s it. One sentence added to your assignment instructions.
This does a few things. It signals to students that AI output is a starting point, not a finish line. It builds the habit of reading critically instead of reading to confirm. And it gives you something genuinely interesting to assess — what did they notice, and how did they correct it?
You don’t need a new unit or a professional development day to start this. You need one extra sentence on your next assignment sheet.
The habits are hardening. The question is whether we help students build ones that will actually serve them.
