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

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?

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.

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.

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.)

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.

🫡 Audrey Watters on the Khan Academy segment on 60 Minutes. 2ndbreakfast.audreywatters.com/12-years-and...

Sarah Robertson, a former seventh-grade English teacher who's now a product manager for Khan Academy, walks Cooper through the process remarking that, when she was teaching, she had 100 students; if she spent 10 minutes on each of her students' first drafts, that was 17 hours of labor. "The burden that we place on teachers to give that specific, timely, actionable feedback is just so great that it's just not possible," she says. But perhaps the solution here isn't to have students write their paper for robots; perhaps teachers should not have 100 students.

I just asked Khanmigo for help solving a math problem and said "idk" every time. Very interesting results. If you're tutoring a kid and they ONLY respond to you with "i don't know" every time, what's your move?

An exchange with Khanmigo where I say: I'm trying to find the integral of x^3*sqrt(4+x^4)dx. Can you help me?

And Khamigo says a bunch of nice suggestions Socratically and I respond with "idk".

Another great piece from @ddmeyer.bsky.social. This one skewers Sal Khan and Khan Academy. I love this critical thinking and pushback against a millionaire trying to shape public education. #EduSky danmeyer.substack.com/p/five-inter...

Other countries level the playing field for their kids through redistributive policies like child welfare, public housing, nationalized health care, etc, all of which would require increasing the tax burden on economic elites. It should not surprise us to see which of those dreams receive fawning coverage during primetime corporate media.

Something like 80% of "good teaching" is having a small set of durable routines that help kids do their best thinking. I supported a Grade 8 teacher yesterday and marveled at how she set the noise level & duration in one quick motion that everyone understood.

A timer with five minutes set and the noise level set at 0.

I taught a new group of kids last week and I got the sense they wanted answers to three questions ASAP. 1️⃣ Do you like me? 2️⃣ Do you like what you teach? 3️⃣ How much do you expect from me? I think every teacher answers those three questions in their first hour even if no one says anything out loud.
