Unbound Academy hasn’t replaced teachers with AI

This is a good article. Dan Meyer, like his PhD supervisor Jo Boaler, is very much in the camp that traditional classroom education is good, and that improvements come by working through school districts, administrators and classroom teachers.

I'm not saying this to cast doubt on any of the facts in the article. Just pointing out that Dan, in general, has a less optimistic view of AI in education, than I'd expect of the median HN commenter.

That said, I'll share my thoughts on Alpha School, based on everything I've read (both things published by the school, and things I've read from parents online and in private forums):

- the '2x growth' in their marketing is way oversold; their typical 4th grader isn't doing math at the level of a typical 8th grader.[0]

- the '2 hours/day' in their marketing is oversold; students often work longer than that.

- only 25% of their students use Math Academy. The rest use IXL or ALEKS.

- in their charter school application, the amount they proposed charging for their software platform was unreasonable, given the minor role it plays in outcomes (10% according to Matt Bateman, who works there) [1]

- the core idea of their 'timeback' platform (that monitors student activity in realtime via video camera and screen recording) is good, but I have not seen it and have no idea whether it's real or how good it is

The intellectual pedigree actually explains everything. Jo Boaler is the one responsible for charging $5k/hr to advise schools to end middle school algebra. In an amusing confluence of concepts, Garry Tan (CEO of YC - whose site we're on) describes her as "infamous and disgraced"[0].

I don't know about that, but when I discovered that San Francisco schools weren't teaching algebra I was at first impressed that American children were doing Group Theory in 8th grade (something we only learn in the 12th standard in Tamil Nadu in India where I'm from) and figured moving that to 9th isn't a big deal only to find that they meant the basic stuff (linear equations and the like, what we learn in the 7th grade).

Honestly, I can't take anyone seriously who would try so hard to set back children from learning what is fairly basic Mathematics at that age. Children are capable of learning this. Or at least a sufficiently large amount are that we should be teaching them to a high standard.

For Alpha School, I think the Slate Star Codex review is likely more informative than this clearly polemic article.

0: https://x.com/garrytan/status/1953654484997169443

tl;dr This is from the people who want to delay Mathematics education to later in a child's life (algebra to 9th grade onwards)

Ironically, by taking the author of this article seriously, the preceding comment makes a more much persuasive critique.
arjie•9m ago
I suspect most people will land on this where their predilections already lead them. To me, the effort to delay Mathematics education is sufficiently bad that I can dismiss the rest of that school of education without much concern. If they are right, they are right by accident and there's not much to learn there. I know there are others like me out there, and for them a quick reminder of who this person is will probably be sufficient for them to escape reading (what they will believe to be) a low-quality post. Time isn't infinite after all.

If you feel less convinced by this, it's simply that you're not in my audience. But I think it's probably worth sticking a tl;dr on the original. Let me do that.

From the blog run by this commentor:https://wiki.roshangeorge.dev/w/Blog/2025-08-14/Crime_Rates_...

Alternatively titled: How to "unskew" homicide data to include everyone in ear or eye shot of a crime to deal with the "problem" of American cities being per capita safer than rural areas.

His comment didn't engage with one bit of the linked article, just ad hominem by proxy. And his blog shows that is how he thinks so don't expect anything more here.

Being a teacher nowadays must be tough, low pay, students that don't respect their teachers, low-attention span of kids due to tech.

Regarding the 'low pay' part of your comment.

Pay varies significantly between different states and cities.

There are elementary school teachers in San Francisco whose total pay and benefits in 2023 were $150k or more:

https://transparentcalifornia.com/salaries/search/?q=Eld%20C...

And to compare those salaries to other jobs, you have to consider:

- the typical academic achievement of those teachers and the alternative roles available to them, and

- the fact that in another role they would have to work 25% more (50 weeks per year instead of 40 weeks per year)

In 2025 San Francisco we have ads on buses advertising low income housing to people making less than $185k/year.

America really does sometimes looks like a first world and third world country in a trench coat.

Also kind of important to have teachers that can live within commuting distance of where they are teaching, so CoL ends up pretty important. Even more so if you want teachers that are older than, say, 22 and might have a partner and/or kids so won't want to live in a studio or have multiple roommates.

The social structure of a typical American public school is prisoners and prison guards. Why would any of the prisoners have respect for the prison guards? Most of the prisoners aspire to be something higher paid and less degrading than a prison guard. They aren't role models, they are just captors.

> students that don't respect their teachers

Depends on where you teach. Some communities are much better than others.

I believe the majority of those reading this message have kids who respect their teachers (or if you had kids they would). You also live in an area where other kids respect their teachers if you have a choice (some of you don't, but if you have the choice and you will make that choice).

Near where I live there is an "inner city" school where the average teacher has been teaching for about 9 months - despite many teachers who have been there are 30 years. The typically teacher works just long enough to get some experience and then gets a job at a "suburban" school that pays less(!) but the students respect the teachers more.

> low-attention span of kids due to tech.

Kids have always been low attention span. Things are probably better than before because we have ADHD treatments that work that we just ignored in the past. Blaming tech is just the latest thing, but you can always find parents blaming low attention span on whatever the latest fad to blame it on is. Truth is kids are not really "designed" to sit in a classroom for hours every day - but it is still the best way we have to set them up for a modern life so we force it anyway.

I think it's a thing with regard to tik tok videos for example where they use split-screening (main content plays on top, and some car doing flips plays on the bottom)

Also when I was in school we didn't have smart phones, at least a slide phone with a full qwerty keyboard was the latest thing, can do a lot less than a full computer in your pocket/social media

There's a lengthy, and quite good, deep-dive into Alpha School by a current parent here, for anyone interested. Spoiler, "AI" isn't that big a portion of what they're doing, but some of their insights and systems around student motivation are actually interesting and very effective.

I heard one of the founders interviewed on the Hard Fork podcast[1] (which confusingly is primarily concerned with AI, rather than crypto.) I went in with very negative expectations, but came away with a positive impression and optimism that they might be onto something. As you say, AI is not core to the project. Instead, the focus is on using technology to facilitate individualized learning. It is true that teachers are 'replaced', but by humans whose job it is to keep the students focused and motivated, rather than to convey information.

I had the same reaction to this podcast:

https://joincolossus.com/episode/building-alpha-school-and-t...

I like the vision and believe in the good intentions. I don't know whether they've achieved much so far.

rahimnathwani•6m ago
If your child took the MAP Growth test in Fall 2024 or Spring 2025, you can compare their RIT scores to the mean score of an Alpha School student in the same grade:

https://go.alpha.school/hubfs/MAP%20Results%20-%2024%2025/20...

Assuming a normal distribution, this will indicate whether your child is above or below the median Alpha School student. This may be impact your view about how well Alpha School is doing vs whatever school your kid goes to.

The tech industry has played a big role in scamming society into changing education to conform to them, instead of the opposite. Nowadays, schools are trying to "educate" children to use technology and in the process they're making the other more important goals become secondary. Critical thinking, reading, writing, math skills, etc., are all going down because schools think it is more important to use the latest gadget and software.
twothreeone•13m ago
Not to go against the OP, but that headline has to be one of the dumbest framings I've seen in a while.. why would you want to replace human teachers with machines? There are an estimated 250 million kids going without any kind of schooling in the world [1], if AI could provide even the most basic kind of education to them it would be a net benefit.

Realistically though, how would it ever come to that? This sounds like the least profitable thing anyone could do.
somethoughts•4m ago
I feel like it'd be perfect if all these school replacements (home-school, charter school, online only schools) went after replacing the dearth of quality after school options.

Really the only options for after school activities after graduating from elementary school are competitive sports, competitive math, competitive music, competitive chess, etc. which are pretty much all zero sum in nature.

I'd love options for kids that let them gradually explore their interests to help them discover future vocational interests in a way that was beneficial to society such that they don't have an existential crisis when they hit senior year in high school and have to pick a college major.
