This video is THE sign of the times for me, a loud alarm indicating that the arm’s race between teachers and students around AI is headed towards disaster. I explain why & offer a solution here: https://t.co/xp6CMmiJs2

@josephjconnor In the last 100 years, we desegregated schools and passed sweeping laws including students with disabilities. I guess it’s cool my neighbor can open a school for 12 kids in what used to be a Foot Locker at the mall, but let’s please get a grip.

[Dan Meyer @ddmeyer]

Teachers and students have different jobs, yes, but both exist in a social compact that says, "We will both bring the HEAT here. No weak stuff." And with AI lesson plans & grading, kids increasingly see their teachers as bringing weak stuff.

[Dan Meyer @ddmeyer]

High school kids in Vancouver, WA, walked out over AI. An organizer:

> I don’t think it’s fair that teachers get to use AI in lesson planning and grading and that students can’t use it for anything.

I’m a huge fan of the Super Wrong, Kinda Right routine. A meager math problem can nourish a bunch of kids when you ask them what the answer CAN’T be and how they know. https://t.co/mOrIj01Ts1

@mbateman Does the same go for other essential services? Would you be this upbeat if ProPublica reporters were able to establish a hospital with a couple of clicks and collect Medicare funds—no standards, regulations, or inspections?

[Dan Meyer @ddmeyer]

@jarredgeller Nice.

[Dan Meyer @ddmeyer]

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."

@Eliana_Goldin "Where's the evidence that Alpha School actually works?" so I reluctantly had to let him cook there.

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?

[Dan Meyer @ddmeyer]

@aaronharnly Many such cases.

[Dan Meyer @ddmeyer]

@ben_m_somers → What curriculum wraps around the interactive?
→ What question is the student trying to answer with this interactive?
→ How does the interactive activate the student's existing knowledge?
→ How does the interactive connect to a social learning environment?

[Dan Meyer @ddmeyer]

@ben_m_somers Learning generally requires more than watching videos, even interactive videos like these animations.

[Dan Meyer @ddmeyer]

@profplate Good question. Since July 25, several studies have been published showing negative results for student AI use (e.g. Strömberg, et al, 2026) and teacher AI use (e.g. Sungu, et al, 2026). These have been reported on widely in the mainstream press.

[Dan Meyer @ddmeyer]

People aren't buying it, folks, sorry.

[Dan Meyer @ddmeyer]

@griswold I'm not sure A & B are so easily quantified but I agree that more public school leaders should articulate that the public has tasked their schools with broader goals than just maximizing an individual student's academic learning outcomes.

[Dan Meyer @ddmeyer]

It's all over tech-adjacent Twitter. "Kids can learn 2x ... 5x ... 10x! ... faster than in regular schools." My question, always, is "... learn WHAT?"

[Dan Meyer @ddmeyer]

@griswold Two goals are in tension: a) maximize a kid's individual learning outcomes b) prepare them to live in a pluralistic democracy with people who aren't as smart as them. Many parents do not value (b) as a goal. Fine, but many do, and I'm naming it as a goal, one that isn't free.

[Dan Meyer @ddmeyer]

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.

[Dan Meyer @ddmeyer]

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.
