I'm pretty sure that Number Snake is from a set I "published" five years ago! (I'm not mad, I'm pleased that it found its way to you!) t.co/hKEb8ox3Ef

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.

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.

Apparently just responding with "idk" over and over can trick an AI tutor into solving a math problem for you... Good to know! @ddmeyer.bsky.social

The Unbound Academy grift as summarized by @ddmeyer.bsky.social includes this self-dealing: "It is a conflict of interest, then, that 100% of Unbound Academy’s named board members are affiliated with th[e] vendors" whose services the board is paying for with public dollars.

Okay you might have heard about Unbound Academy & 2 Hour Learning. Ads all over social. Lots of press coverage because they got a virtual charter approved in AZ behind claims they've replaced teachers with AI. Things are more AND less than they seem here. 🧵

Unbound Academy, an AZ charter school claims to have replaced teachers with AI with students learning 2x more than usual. I read their application in AZ, but ALSO in UT, AR, NC, SC, and PA. It's wild. Sending out my report tomorrow. Subscribe here. 👇 danmeyer.substack.com

🫡 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

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.

Ahhh thank goodness, @ddmeyer.bsky.social watched 60 Minutes go back to the Hype Well for Sal Khan so I don't have to. What's it gonna take for folks to stop listening to someone who's been so consistently wrong about the future of education? (Sal, not Dan) danmeyer.substack.com/p/five-inter...

As of today I have received:

Very curious what's next!

People are right now slobbering pretty hard over this AI tutor demo over on LinkedIn. I think it's a mess—pedagogically, socially, and mathematically. What do you notice?
