My daughter tried the first prototype of Super Teacher when she was 5. Now she's 7, and the app is available on the App Store. getsuperteacher.com/t/1 They grow up so fast! ❤️😭

@BaseballQuotes1 They totally had him at 3rd base with a perfectly executed wheel play, just a bad throw by the third baseman. That play will be haunting the third baseman's dreams for years.

@pandemona What's so hard to understand? From the people who brought you Nest, Nest Cam, Nest Home Max, Nest Essential, Nest Premium Wifi Pro, Google Home/Premium and Nest Aware Plus...it's Google AI with Flow, Whisk, Mariner, Gemini, NotebookLM and AI in Google Workspace AI. Simple! ✨

are we supposed to know what each of these brands do?

@zachweinberg What is fundamentally limiting growth in the supply of new doctors in the US to meet the demand? Is it the AMA acting as a guild? Is it the cap on federal funding for residencies? Both? Other things? I know nothing about this stuff. You must know the core reason(s).

The primary reason US healthcare is so expensive, but also why we can get appointments reasonably quickly.

@craigcitro This counterexample in academia is "recent" in the sense that he's currently the president of Bard College, but not so recent in that he ascended to that position in 1975. He did so at 28yo, coming from another college presidency which he started at 23yo). en.wikipedia.org/wiki/Leon_Bots…

I think there are lots of counterexamples, but this is still a pretty interesting observation (in particular tech has both examples and counterexamples in all shapes and sizes, but much less so in academia)

@MrZachG @tetheredtoed1 You can say that again. IMHO it was a very debatable choice to include this specific AI Slop in this specific post. Are you experimenting with entirely AI-generated twitter posts by any chance? Not a wise choice IMHO. (I'm still a huge fan though! :-D)

@tetheredtoed1 Ai slop

When you engage in fact instruction, you’re not just teaching isolated facts - you’re teaching a fact system. The relationships and the arrangement are the curriculum. If kids don’t learn the system, the individual facts have nothing to stick to.

@MrZachG You should try @getSuperTeacher with your kid. getsuperteacher.com/parents And let me know if you'd like to get involved!

Can students learn from educational video games? The research on "Serious Games" suggests yes - if they're *serious*, in the sense that there are a lot of layers of instructional support. I name and discuss these in this substack post 👇👇

@GustafssonEinar @rastokke @SondreGrinna @PamelaSnow2 I recently visited Norway for the first time and Tromsø was awesome. The set of fun activities we did there was definitely not ø. Anyway, looking forward to another year of Chalk & Talk!

@rastokke @TimNovikoff @SondreGrinna @PamelaSnow2 A fellow Trønder then :)

A different perspective: 2025 Chalk & Talk top listener countries adjusted for population: 1. 🇦🇺 Australia! 2. 🇨🇦 Canada 3. 🇳🇿 New Zealand 4. 🇳🇴 Norway 5. 🇺🇸 United States 6. 🇸🇪 Sweden 7. 🇮🇪 Ireland @GustafssonEinar @SondreGrinna @TimNovikoff @PamelaSnow2

@rastokke @GustafssonEinar Now I'm curious to see the top per capita!

@GustafssonEinar Norway possibly ranks in the top 3 per capita. US has a large population so it makes sense it would rank #1 on overall totals. I'll work out per capita rankings later. Lots of Norway listeners. Attached is from Dec 16, meaning it was #1 podcast in Norway, education category.

Spread the word! The best education podcast out there. For the sake of Norwegian education, I hope Norway rank top three at the end of 2026.

@rastokke I'm in the trenches in the US. IMHO the math pendulum is actually out of phase with the reading pendulum. While there's a rapid re-adoption of known effective methods in reading (phonics etc.), there's actually a rapid abandonment of known effective methods in math (DI etc.)

I’m a mathematician. I teach math. It’s all math, all the time. I met John Mighton 15 years ago, and I’ve been advocating for better math education ever since. Chalk & Talk is the latest. John says he’s more optimistic now than he was then. I’m skeptical about Canada, but encouraged by progress in Australia & Sweden. And by the many people fighting for better education. I’m glad to have found them. E.g., @BarryGarelick @nsachdeva2019 @MrZachG @sjhill1 @JessWorden @brian_poncy @PamelaSnow2 @ToddTruitt76508 @JRED530

@justinskycak You might enjoy this paper of mine from grad school: pnas.org/doi/10.1073/pn…

In spaced repetition, there is a concept of theoretical maximum learning efficiency. In theory, given a sufficiently encompassed body of knowledge, it is possible to complete all your spaced repetitions without ever having to explicitly review previously-learned material.

@rastokke @MrZachG It's a constant struggle to avoid this result, bc my wife and I are both math teachers with graduate degrees in math. It's been playfully brought up many times by other math-y parents. Happily I have the perfect out, which is to recommend they use Super Teacher.

@MrZachG Be careful. That’s how I ended up with kids coming to my house every week to learn math :)

Breaking: Parents in my neighborhood school figured out their children are below level in math and reading and are super concerned and bouts to do something about it. More as the story develops.

@wtgowers Did you check the proof of the lemma yourself, or did you simply find a trustworthy source for the lemma?

PS In case anyone's worried that it used a lemma I hadn't heard of, I checked that the lemma was not a hallucination.

I crossed an interesting threshold yesterday, which I think many other mathematicians have been crossing recently as well. In the middle of trying to prove a result, I identified a statement that looked true and that would, if true, be useful to me. 1/3

Super Teacher is a Top 20 finalist at TechCrunch Disrupt Startup Battlefield! Always wanted to do this rite of passage from silicon valley. Excited to present on the main stage! techcrunch.com/2025/10/27/the… #StartupBattlefieldTop20

Congrats @barrald and the @_hex_tech team on this exciting launch!

@dubbaumann Yes

Is Google Meets down for anyone else? Never seen it drop before

@C_Hendrick @P_A_Kirschner I'm guessing you won't cover the extremely theoretical work on this, i.e. theorems about mathematical models related to spaced repetition, but in the off-chance that you do, let me know. Happy to chat! (I'm the author of pnas.org/doi/10.1073/pn….)

So @P_A_Kirschner and I just had a “bucket list conversation” with the legend that is John Dunlosky about spacing and retrieval and how to make it work. We’re writing a chapter on the topic and I’m so excited to work on it and share it with everyone.

@VinceBoley @C_Hendrick @P_A_Kirschner Some do, to an extent, generally under other names (e.g. "spiraling"). Many products do it explicitly, such as @getSuperTeacher, which uses it within flashcard sequencing algorithms as well as features like Surprise of the Day (for doing practice problems from recent lessons.)

@C_Hendrick @P_A_Kirschner Why doesn't school curriculum include spacing and retrieval built into it with all the research we have to back it up?

Check out the new Steve Strogatz series in the NYTimes! It's really well done!
