The headline: "AI tutors do just as good as humans at half the cost." The appendix: "We threw out a bunch of students who didn't use the AI tutor enough." Me: "You see how this looks right." Study: arxiv.org/pdf/2609.28470
Robert Pattinson's character from Primetime saying, "You see how this looks right," in front of an appendix outlining exclusion reasons.

Q: "How do we know Alpha School actually works?" So I kinda had to hand it to him.

I moderated a panel a week ago. First question: a man stood up & said, "I recorded this whole panel with Wispr Flow and asked AI what question I should ask you." Deeply unsettling behavior. Like what are we doing here?

My hypothesis: these adults have internalized that the evidence in favor of AI in schools is wafer thin. Maybe also: the labor market seems utterly unpredictable right now so stick to learning about things that have mattered.

People are NOT going for it. What's your hypothesis for this chart, bsky?
A graph showing that adults do not think an AI school best prepares students for the future. 56% vote for a "school that prohibits AI."

All of this and also for writing. Over on "tech-adjacent Twitter" I saw someone bragging about getting a paper written before lunch with the help of better prompting. Doing that won't help you learn what's worth learning.

So s/o to the teachers and schools and parents who are committed everyday to maintaining lofty goals for children's social and mathematical learning, doing a lot with what little they have, unbothered by people who believe it is a great accomplishment to do less with less.

When tech Twitter claims to have hacked learning, their one weird trick for saving time is often just to do LESS stuff — to teach math at shallower depth or to teach kids to negotiate their ideas with fewer other kids who differ from them in fewer ways.

All of those goals are in addition to getting an answer and all of them takes time.

4️⃣ We learned how to negotiate ideas together—how to critique and support one another’s work, how to explore their own path while keeping the group’s needs in focus.

Dan Meyer @ddmeyer.bsky.social · 16/09/2026
3️⃣ We developed our understanding of place value. 4 isn’t two times as large as 2 in the problem above. It’s 200 times larger. It's easy to get the right answer and miss that fact about numbers.

Dan Meyer @ddmeyer.bsky.social · 16/09/2026
2️⃣ We were developing our intuition. We first estimated our answer as a check on our later calculation.

Dan Meyer @ddmeyer.bsky.social · 16/09/2026
1️⃣ We were learning conceptual connections, solving the same problems in three different ways, connecting older methods like area models and newer methods like the standard algorithm.

Dan Meyer @ddmeyer.bsky.social · 16/09/2026
Last week, in fifth grade, the kids spent twenty minutes on two problems. If we only wanted kids to learn to get answers, yes, we could have done that MUCH faster. But here is what we learned BEYOND getting answers ...
An image showing how school teaches multiplication, through multiple methods and conceptual depth, and how edtech teaches multiplication, with just an answer input.

It's all over tech-adjacent Twitter. "Kids can learn 2x ... 5x ... 10x! ... faster than in regular schools." My question, always, is "... learn WHAT?"
Several tweets indicating that students are learning 2x, 5x, or 10x faster than regular school.

I taught a seventh grade lesson on equivalent expressions last week and did something Not Very Nice on the warm-up.
A scan of a printed warmup with the instructions to “pick three different numbers for x and then evaluate them for both expressions in the table. One expression is 2x - 3 and the other is 2x - 4 + 1. The student gets the same value for both because they are equivalent.

Big fan of the Beast Academy books. Can you spot the exact moment here where my kid had an epiphany?
A prompt to “Count by 2’s” and shade in the squares on a 10 by 10 grid from 1 to 100. My kid has shaded in squares individually from 2,4, … 16, and then at 18 he starts shading the entire columns of numbers with 8 in the units digit.

I'm curious how they'll appeal that section. My understanding is they really DON'T do curriculum. I don't think Khan Academy would call itself a curriculum. Curriculum generally requires teachers for implementation.

Pennsylvania denies AI cyber charter school application
Unbound Academy promised students would learn “twice as fast” with AI tutors instead of traditional teachers. The state of Pennsylvania said the school did not provide enough evidence to support that.

Great newsletter from @ddmeyer.bsky.social today. Asked about the choices edtech companies make, Meyer said, “You either bet on teachers or you bet on software, and if you bet on software, you eventually learn you have to build a teacher.” (Note: He does not believe that they can build a teacher.)

I wrote about the difficulty of trying to make a better teacher out of AI like Khanmigo. (Also, 24 hours after I posted this, Khan Academy changed Khanmigo, but didn't fix it.) danmeyer.substack.com/p/in-edtech-...

Something that makes me really sad is seeing the teachers who write the testimonials on AI edtech products having to get second jobs as stock photography models. Teachers like "Michelle (8th Grade Teacher)" deserve a living wage!
A testimonial from a teacher named "Michelle" - "EnkeyAl is really valuable in helping me cater my lessons to expand across various learning styles and keeps lessons interesting and fun."A stock photography website featuring Michelle in ... exactly the same pose as the testimonial.

Unbound Academy hasn’t replaced teachers with AI, as they claim. Their 2x learning in 2hrs, as far as I can tell, comes from replacing poor kids with rich kids. Coming to a state near you. Keep an eye out. More here. 👇 danmeyer.substack.com/p/the-truth-...

I’d love it if 2x the learning in 2hrs were possible in public school, but the only evidence we have is that it’s possible in private schools where parents generally have resources, where kids come to school fed and rested, where parents can afford backup tutoring.

2️⃣ Their board in AZ are also their vendors. Important because the board approves vendor purchases. Software exec MacKenzie Price wants to charge Unbound $6500 / student for software. Who approves that fee? MacKenzie Price, Unbound board prez! Big conflict. Check out PA too! 👇
Excerpts from their charter applications in AZ & PA. In AZ, 2 Hour Learning, Inc, is charging, $2,000 per student per year. In PA, $6,500 per student per year.
