Your Kids Can Learn 10x Less in 10x Less Time!

1 Share
Tweets of people bragging that their kids are learning 2x, 5x, and 10x faster.

“School is too slow for my kid.” That idea is ascendant on Twitter, particularly among tech-adjacent families. They post stories of their kids skipping years in weeks and reading before they can crawl, frequently using software or alternative school models.

I build curriculum and technology for schools, so I too experience a shiver at the thought of kids learning more, better, or faster. But I am also working weekly in a public fifth-grade math classroom this year, which helps me understand that the right follow-up question whenever anyone claims they can help kids learn 2x, 5x, or 10x faster is “learn what?”

Last week, we spent twenty minutes on two problems.

Last week, our fifth-grade class spent twenty minutes on two multiplication problems, both of which a calculator could chew through in nanoseconds, both of which many kids could certainly answer in less time if getting an answer were the only goal.

Those afflicted with edtech psychosis will declare this a profound waste of time—inefficient and pre-modern. The immunized will demonstrate more curiosity here. What else were those students doing besides calculating answers more slowly than a calculator? Here is an incomplete list:

  • They were developing conceptual connections. They solved the same problems in three different ways, connecting older methods like area models and newer methods like the standard algorithm. Without those connections, many kids would inadvertently learn ideas like math is magic.

  • They were developing their intuition. The teacher asked them to estimate the answer first as a check on their later calculation.

  • They were developing their understanding of place value. 4 isn’t two times as large as 2 in the problem above as it seems to many students. It’s 200 times larger. The standard algorithm conceals that fact while partial products and the area model bring it into the sunlight.

  • They were learning 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. During a period of independent classwork, some kids moved farther through the problem set than others, but everyone returned at the end of class to consolidate their learning together.

The public has set out two goals for classrooms here:

  • Teach math at a certain level of conceptual depth.

  • Teach dozens of different kids to negotiate their ideas together.

The public can debate those goals, of course, but they require resources, chief among them time. Doing more stuff generally requires more time. One weird trick for saving time, more and more parents are learning, is to commit to fewer goals. For example, 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.

Schools should always work to improve and always take seriously how much of a kid’s only childhood is spent under its care. I’m never going to be content with the work we do in schools, but I will always be impressed by the teachers, schools, and parents who commit every day to meeting ambitious goals with what few resources they have, to do more with less, unbothered by people who believe it is a great accomplishment to do less with less.

I write a new post about teaching, technology, and math on special Wednesdays. Toss me your email to get the next one. -Dan

Paul Jorgens is a long-time high school teacher who has also had the chance to teach fifth grade recently:

There is so much going on in the 5th grade world. I should have done this earlier in my career. There is much to learn from an elementary school teacher. The next week I subbed for a day in high school. A different energy was needed. Last week I modeled a lesson in a 7th grade classroom and did some observation at that middle school as well a different high school. There is a common thread. In all of those rooms the most important resource was the students. Their voices need to be heard and their contributions honored. We also have a great resource among our teaching colleagues. There is so much to learn from each other.

Checking in on Our Friends: Alpha School

Recently, I shared evidence that Alpha School hasn’t lived up to its predictions for its public school Unbound Academy. Here is some Alpha School media that has interested me in the weeks since.

¶ No one at Alpha School responded to my request for comment on the Unbound Academy results, but Craig Barton had Alpha School principal Joe Liemandt on his podcast and asked him about them.

CB: It seems that the results [at Unbound Academy] are not quite to the level that your schools are. What does that tell you about the barriers for scaling? What has Unbound not got that Alpha has?

JL: Great. So I don’t want to speak for Unbound because it’s actually a school that we don’t own and so they need to speak for themselves, but I can talk … I have ones I own that are similar so I can talk about it.

Unbound Academy is non-selective and tuition-free. The schools Liemandt goes on to discuss are selective and fee-based, which are crucial differences.

The Unbound Academy director org chart. We see employees of Alpha School here.

(p. 187 of Unbound Academy’s charter application)

Also, Liemandt seems confused about something important here. Of course he doesn’t own Alpha School because no one owns a public school. The closest thing a public school like Unbound Academy has to an owner is its board of directors which is responsible for ensuring the school meets its obligations to the people of Arizona and the commitments it made in its charter application.

And Unbound Academy’s founding board president was MacKenzie Price, the co-founder of Alpha School. Her husband, Andrew, was the board treasurer. The other two named directors are long-time employees of Alpha School. Liemandt acts like Unbound Academy is some independent franchise, but all four of his employees are still on its board. Disavowing Unbound Academy is like a district’s school board members disavowing responsibility for its schools. All of those people attached their names to huge promises of academic growth that Unbound Academy didn’t deliver. None of those people have answered to Arizona taxpayers for promising 60% math proficiency and delivering 10%.

Andrew Woo spoke with Unbound Academy’s head of school, Michael Goto, finding that Alpha School’s promise of “2 Hour Learning” is slipping as they integrate their model into public schools.

Michael Goto, Unbound’s head of school, told me that students spend about 2.5 hours on learning apps each morning, plus another 1.5 hours on Mondays and Fridays. Virtual afternoon clubs include chess, invention and broadcasting. Teachers monitor students online and can pull them into breakout rooms when they get stuck. But if a student never logs in or closes the computer, staff text the family. Repeated incidents lead to an intervention meeting.

Four hours of dedicated app time in a day is a pretty big pill to swallow. I’m curious to see what other parts of a model built for the wealthy will have to change in response to the needs of public school students.

ProPublica and the Texas Tribune reported that one of Alpha School’s other public school experiments has not produced the results promised by Alpha School either.

Texas Preparatory School received its third consecutive F rating, largely based on the test scores it received during the partnership with Alpha.

A table showing SAT averages of incoming Alpha High School Freshmen (1350) and the Texas average (978).

¶ Alpha School claims it doesn’t screen its applicants for academic achievement, but somehow it has selected freshmen with elite academic achievement—SAT scores that are, on average, 38% higher than the average Texas student.

¶ Ex-Obama guy Ravi Gupta had me on his podcast Lost Debate to discuss the model and why it hasn’t worked.

¶ There are a bunch of concerns online about Alpha High School’s start-of-school bootcamp. The New York Times also has an interesting piece on the connections between Alpha School, 2 Hour Learning, Guidepost Montessori, and (?!?) AltSchool. That last one really lights up the corkboard conspiracist in me, but look—I have a lot on my plate right now. I can only get so worked up about rich people getting hand-me-down assets from other rich people. I can only get so worked up about how rich parents decide to parent their rich kids. My interest in Alpha School is pretty tight: Is there anything here for kids outside the top tax bracket? Can 99% of schools learn anything from Alpha School? I’ve gotta stay focused, I’m sorry.

A Severe Misalignment of AI in Mathematics

1 Share

I am proud to be among the list of 25 initial signatories — all Fields Medallists — to the declaration below, which grew out of discussions between ourselves over the last week. We have also posted our declaration on this web page, and (similarly to the Leiden declaration) invite further signatures. (It is unfortunate that we did not have the time to have a more consultative process, as with Leiden; but we decided that the urgency of the situation was such that we needed to release a statement sooner rather than later.)

See also this recent article in the Economist regarding our declaration, and a brief interview with James Maynard on this topic. A French version of this declaration was published in Le Monde.

Over the last few months, the mathematical capabilities of LLMs have improved dramatically, to the point that they can solve major outstanding problems in many fields of mathematics. However, the push by AI companies to solve mathematical problems as a benchmark is detrimental to the science of mathematics, and to the mathematical community. The goals of the AI companies and the goals of the mathematical community are severely misaligned. We see these as part of broader alignment issues impacting other scientific and creative professions, as well as the whole of society.

Research mathematics deals with understanding basic structures of shapes, numbers, and natural phenomena. Over the course of generations, it has built a large corpus of sophisticated ideas, methods, abstractions, and other tools to comprehend the mathematical landscape. In turn, modern technologies and sciences are based on mathematical tools.

Famous problems have often served as landmarks and lighthouses against which one can measure an improved understanding of this landscape. Solving one of these problems has been a certain sign of new insights and interesting methods, which would then be studied by a community of mathematicians, through a long and arduous process of talks, discussions, simplifications. At the end of this process, one will ideally find a textbook presentation of the results suitable for any graduate or even undergraduate student to study. Some of the mathematical ideas pursue their journey even further to become, decades or centuries after, tools that are understood and used by the whole population.

The mathematical community functions, in many ways, as a miniature version of humanity. It consists of individuals using a wide variety of different approaches, joined by core values. The most precious resources of our profession are students and ideas, and these we nurture with great care. We feel responsible to let them grow to their full potential, until they can live a life of their own in the mathematical world. For students we often suggest problems with the core intention of developing skills making them well-positioned for advances in research and elsewhere. Our ideas we disseminate in talks, private discussions and careful writeups, connecting them to the previous ideas of others. These processes invariably take time and are based on human interaction.

In recent months, the success of AI in solving major mathematical problems has made headlines even outside mathematical circles. But solving problems is only a tool and proxy for achieving the primary goal of conceptual understanding and insight. Forgetting this in the world of AI may turn the tool against the primary goal. Indeed, the mass production at faster and faster pace of “true/false” statements could destroy fertile ground instead of breathing life into new ideas.

Often these solutions are announced in a rush, leaving no time for a proper writeup, the isolation of new methods and ideas, and citing relevant previous work of others. As in all creative professions, this raises severe attribution and plagiarism questions. Moreover, without the willing mathematicians who must take care of their development and integration into the mathematical canon, AI-conceived ideas would never become fully alive and the crucial human transmission chain between mathematicians would be lost.

We are witnessing a general threat to intellectual work, with misalignment between the outcome of the use of AI and its initial purpose. In many fields and activities, years of training have traditionally served not only to produce a final answer or product, but also to develop understanding and the ability to formulate new questions and ideas. However, building on a vast body of previous human work, AI systems are becoming increasingly capable of producing the results of such work directly, and these goals cease to align. The issues the mathematical community faces now are similar to issues that other scientific and creative professions are facing, and indicate issues that all of humanity might face: how to make sure that, as AI changes the way work is done, we do not lose sight of what that work was meant to achieve in the first place.

AI offers the potential of enhancing and accelerating genuine mathematical study and understanding. Mathematics as a profession will need to adapt to these changes in several ways. However, whether these changes ultimately benefit the field or have a destructive effect will in large part be determined by the decisions of the humans in control of this new technology.

These issues must be addressed urgently, in the mathematical community, by the companies developing these technologies and, more broadly, by a society that will confront similar problems in many other forms of intellectual work.

Quoting Paul Ford

2 Shares

For a while, I must admit, it looked as if software developer roles like mine were done for. How could we fight against tireless robots? But our industry is slowly realizing that making truly cutting-edge software still requires humans to think and work together, to maximize their skill sets and to practice their respective crafts. A.I. can write very good software, but it also makes it easy to do someone else’s job badly, which is part of why all those projects fail. Now that everyone can code, it’s become clearer why many shouldn’t.

Perhaps you’ve read Ben Riley’s exposé on AlphaSchool’s “boot camp” -- along with his follow-up in which the school provides even more creepy details on the bizarre eight-week training program that high school students enrolled in the private school must complete.

Perhaps you haven’t.

Perhaps you’ve blocked from your memory the whole AlphaSchool insanity: the promise of “two hour learning” – two hours a day spent clicking through AI-mediated educational programming – that seems to have captivated the imagination of the usual crowd of tech investors and evangelists (and sadly, a fair number of journalists). I don’t blame you. Indeed, I congratulate you if you've been able to ignore it, as the hype-sters won't let us go a single day without hammering us with how transformative (and terrible) the "AI" revolution will be.

Or perhaps, like me, you simply cannot believe that we’re still talking about this very ridiculous "AI" revolution and, in particular, this very ridiculous school. (I’m cited in Ben’s piece calling AlphaSchool “snake oil” and I stand by that – the “two hour learning” claim merely the latest in a long history of educational gimmicks and fads where some hustler claims their product will enable buyers to quickly, even instantly, acquire new knowledge.)

Honestly, I felt as though Dan Meyer thoroughly debunked the whole premise of the school – and not just the “two hour learning” with “AI” instead of teachers bullshit – when he first wrote about AlphaSchool over a year ago. Over a year ago.

But instead of letting a bad idea fade away – and yes, we could say that for this whole “AI” brouhaha – there’s a group of very committed people sold on, and in turn, selling the story. It's exhausting and it's depressing, particularly as too many decision-makers in too many places still believe there is a magic ed-tech bullet. AlphaSchool keeps expanding to new cities and new states, even though it’s never being able to show that it works for all (or hell, even most) students. Indeed, reporting from Wired and 404 Media (and elsewhere) has underscored that there are all sorts of bad things afoot: both in the AlphaSchool software systems and in the classrooms themselves.

(I’ve noted this before...) There’s a scene that’s been stuck in my head for over a decade now, from a 2012 episode of PBS NewsHour, in which journalist John Merrow explored the promises of “hot new startup/school” of that decade: Rocketship. The charter school chain was also technology-driven (and tech-investor lauded and funded); it also promised to replace teachers with algorithms. Its students, most of them Black and brown children from lower socio-economic backgrounds, sat in colorful cubicles for much of their day, headphones on, bored and isolated and clicking away at their lessons.

For its part, AlphaSchool also has plans to expand into the (historically pretty terrible) virtual charter school territory. But the schools that have made most of the headlines have been its private brick-and-mortar locations – those with tuition that ranges from $10,000 to $75,000 per year. The target population for AlphaSchool aren’t disadvantaged students; and I suppose it might be easy to argue that these more privileged students will be fine even if the two hours of mandated teaching-machine-time is less than ideal, as the rest of their school day (and, of course, the rest of their lives) will be full of fun, enriching activities and opportunities.

“What the hell are we doing to these children?” I thought when I watched PBS NewsHour. To me, Rocketship exemplified the ways in which – despite all the language of “progress” often wielded to make ed-tech seem appealing to schools, to parents, to communities – these technologies and associated practices served to reinforce regimes of surveillance and control, utterly dehumanizing students as it datafied them.

Many of the charter schools that were so popular – then and now, I suppose – with the ed-tech and ed-reform crowds also touted a focus on “character education.” They demanded compliance, indeed often silence, from students. These programs were obsessed with behavior, linking students' outward expressions to their inward development.

AlphaSchool is eerily similar, even though its private schools are not marketed to low-income or marginalized families. AlphaSchool too operates a regime of surveillance and control. As Ben’s reporting underscores, it too is committed to dehumanization, humiliation, shame. And personalized learning software – whether you market it as “AI” or not – always relies on behavioral engineering.

But the “character education” that AlphaSchool doesn't demand silence or compliance in the same way – again, the appeal here is to parents who believe their child is the next genius tech entrepreneur billionaire. But it is damaging in its own right. AlphaSchool, as we can see in the details of the bootcamp, actively demands students mold their behavior and their identity, in this case into some sort of John Galt figure. The school's programming leans into the kind of pseudoscience that litters the pages of bestselling “get rich quick books” – psychological pseudoscience, economic pseudoscience alike – and the ideology of Silicon Valley's startup hustle. All of this is the kind of messaging you can regularly find on social media, no surprise, since this seems to be a school fixated on the anti-expertise of influencer-culture, the sociopathy of tech-culture: move fast and break things.

“What the hell are we doing to these children?”


“Do not obey in advance.”

I often think about Timothy Snyder’s first lesson in his book On Tyranny – his guidance for protecting democracy. "Do not obey in advance." It works for fighting fascism; it works for fighting "AI" – they're inextricable.

Harvard’s president made the press rounds this week, with interviews in The Chronicle of Higher Education and in Derek Thompson’s podcast/newsletter and probably elsewhere too, talking about how “everyone is using ‘AI’ all the time for everything” and thus you should too.

"Do not obey in advance."


This week it seemed as clear as ever that “AI” is being marketed, even by its makers, as a threat. A threat to everything and everyone; a threat to life, to the very idea of future itself.

And sure, it’s a lot of “misleading metaphors” as Melanie Mitchell put it. I don't think that "AI" is going to kill us all (although the rapacious, climate-destroying commitment to fossil fuels and data centers is sure gonna try). But when "AI" proponents say this, they really do mean it as a threat, even if they don’t necessarily believe it to be an existential one. "AI" is a threat, and they want us to comply. They want us to consume. They want us to obey. They want us to click. They want us to cower. They want us to fear. They want us to be reliant on their machinery, their answers, their ideology.

Lars Kenseth, The New Yorker

Of course, as Ryan Broderick put it, “AI is still boring and also bad and also expensive.” Resisting it really shouldn't be that hard. It sucks. Software sucks. The oligarchs' vision of the future sucks.


There isn't really conclusive evidence that asking "good questions" means that you get better answers from "AI." I know it might seem true. We're taught that asking good questions – learning to form and ask good questions – is essential to knowledge acquisition, to knowledge expansion. We glorify the Socratic method. We admire people like Terri Gross, for example, because as an interviewer she has a knack for asking very good questions that, in turn, elicit very interesting responses from the guests on her show.

But that is not how LLMs or chatbots function. "Good questions" aren't necessarily what elicits "good answers" – indeed no amount of "good questions" will consistently lead to a "good answer" from a probabilistic technology. Learning how to type "good questions" into the chatbot, teaching students to think of their inquiry as "prompt engineering” – these involve demanding students bend their thinking, in form and in content, to suit the interface, the machinery of surveillance and extraction.

Sure, asking questions is important. We should all wonder. We should be curious, and we should all have the right and the courage to question. But forming those questions – even outside the chat interface – is just one piece of how we think and learn. The questions themselves are never really the goal; but nor are some sort of finitude in the answers we uncover in turn. And questions are not always framed first or formed fully before understanding starts to happen.

We aren’t machines, so let’s stop instrumentalizing every part of our cognition, constrained by that terrible metaphor.

(We might stop to think too how, in light of all the compliance that the technology industry craves from us, “good questions” – again, whatever that means – are the one place where they promise we will still retain agency and control over "AI." See? Maybe “good questions” really don’t matter at all.)


“Comparable results have been obtained with pigeons, rats, dogs, monkeys, human children… and psychotic subjects. In spite of great phylogenetic differences, all these organisms show amazingly similar properties of the learning process. It should be emphasized that this has been achieved by analyzing the effects of reinforcement and by designing techniques that manipulate reinforcement with considerable precision. Only in this way can the behavior of the individual be brought under such precise control.” – BF Skinner, “The Science of Learning and the Art of Teaching” 1954

Some zoos are using “high tech” toys to stimulate their captive animals, and The Atlantic asks “Could high-tech toys help captive animals act more wild?

What the hell are we doing to all of creation?

Today’s bird is the Namaqua dove. I’m also fascinated by which birds get the “dove” moniker and which are stuck being “pigeon.” The Oena capensis is a pigeon – a very small pigeon and the only species in the genus Oena. The bird is only about 22 centimeters in length (about the size of a budgie, for reference), including its very long tail. Its range extends from sub-Saharan Africa to the Arabian Peninsula.
