Meaningful learning for students. Real support for teachers. That’s what great math instruction should look like. ❤️

A Wharton economist ran a randomized controlled trial on almost a thousand high school students in Turkey.
The result was so brutal for the AI-in-education narrative that it had to be peer-reviewed by PNAS before people would believe it.
Her name is Hamsa Bastani. She teaches operations and information at the Wharton School at the University of Pennsylvania, and the study she published in 2025 alongside her co-authors is one of the cleanest experiments anyone has run on what AI actually does to learning when you remove it from the equation and check what is left.
The setup was a randomized controlled trial, the same methodology used in clinical drug trials. Nearly a thousand high school math students in Turkey were split into three groups and put through four sessions of ninety minutes each. One group practiced with GPT Base, a standard ChatGPT-4 interface that could answer any question directly. One group practiced with GPT Tutor, a version of the same model that had been prompted to guide students with hints rather than hand them the answer. One group practiced with nothing but their textbook and their own head.
During the practice sessions, the AI groups looked like a miracle. The GPT Base group solved 48% more problems than the students working alone. The GPT Tutor group solved 127% more. Every administrator looking at those numbers would have written a press release about the transformative power of AI in education and moved on.
Then the actual exam came, and AI was not allowed.
The students who had practiced with GPT Base scored 17% worse than the students who had practiced alone. Seventeen percent worse, despite having solved nearly half again as many problems in the sessions leading up to it. The students who had struggled the most, who had sat with the confusion and worked through it without a tool to rescue them, were now the only ones who could actually do the math when it counted.
Bastani's team read through the chat logs to understand what had actually been happening during the practice sessions, and the answer was exactly what the exam results had already implied. The GPT Base group had not been learning. They had been extracting answers and moving on, and every moment that felt like understanding was actually the model doing the cognitive work while the student's brain waited for the next problem to arrive. The paper describes it precisely: without guardrails, students attempt to use GPT-4 as a crutch during practice, and subsequently perform worse on their own.
The detail that should follow every conversation about AI in education is the one buried in the post-test survey results. The students who had relied on AI the most during practice were also the most confident they had understood the material. The tool had not just failed to teach them. It had convinced them they had learned something they had not, which is a different kind of failure entirely and a much harder one to correct because the student has no idea it is happening.
The crutch had made them confident and weak at the same time.

Putting everyone in the same math class doesn't help weak students, slows down achievers -- and exhausts teachers.

Need to give students more room to write and solve math than a traditional worksheet?
✂Cutouts ✂ allow you to separate questions and spread them out.
Give students all the elbowroom they need to think and do #math.

"Archimedes" math standards are simpler than Common Core math. Are they better?

Will learning the times tables make a comeback in California and New York? Math facts are to math as phonics is to reading.”

Remedial math was a dead end. Abolishing remedial math didn't help unprepared community college students.

What's the best way to teach math? Will a mix of explicit teaching and inquiry end up like "balanced literacy?"

So crazy it might work: Test to see who needs more help learning math and provide help immediately, so kids don't fall so far behind they give up.

Some states don't allow standard math algorithms in elementary school. But let teachers teach—they'll get students where they need to be. #TeachMath

The old math is new again, as countries try to escape the "math doom loop."

At top ed school, ex-engineer learned about equity, culture. 10-15% was on how to teach math. Many classmates were "scared" of math.

Teachers get bad -- or confusing -- advice on how to teach math. Students do little or no math homework. Achievement falls. Gaps widen.

Common Core math gets kids from arithmetic to algebra, say fans. But some states have ditched "crazy math."
