I'm a former physics teacher, and while I'm impressed by the technology, I think this is a low efficacy innovation. The real challenge in teaching Newton's laws of motion to teenagers is that they struggle to deal with the idea that friction isn't always there. When students enter the classroom, they arrive with an understanding of motion that they've intuited from watching things move all their lives, and that under…

Hush! Don't bring teaching experience into these discussions, you will trigger the EduTech people who have been promising a teaching revolution for 15 years already.

All the people at the forefront of AI really loved and thrived in highly academic settings from kindergarden to PhDs, their own lived experience doesn't match up with this product at all. Why are they making it? EdTech has the worst returns of any industry in venture capital. Why? There are no teachers who say that technology has generally improved experiences in classrooms, even if some specific technology-driven ex…

> EdTech has the worst returns of any industry in venture capital. Why? I think this one is fairly simple. Half of consumer spending comes from the top 10% of earners, whose kids we can assume have generally pretty decent educations already. The people who need education help the most don’t have money to spend on it. The parents who do have money to spend want to invest in tailored education from a human teacher, not…

> So if you want to make money, you need to focus on things like enrichment and test/college prep for the top 10%

But there's no potential market in the top 10%. I mean, these people just hire a good teacher and that's it. There's no room for improvement; there's nothing that can beat a good teacher.

> Helping inner city kids who are 3 grades behind in reading doesn’t print money

This is a political problem. Political problems cannot be solved by technological means. So there is no market here either.

I love learning new things, Khan academy got me all the way through college, and I use ChatGPT / Claude to help me study papers regularly. I got frustrated really fast. Here is an example: https://learnyourway.withgoogle.com/scopes/1KNlGW5E/immersiv... It starts with just this sentence, followed by a quiz on that sentence: > When we are born, we inherit our genetic makeup and biological features. However, our identit…

It isn't you. None of those answers are correct. Sociology studies societies and cultures; collective behaviors at different scales within different niches, etc. It's an LLM hallucinating again.

Ignoring that, NONE of those answers are correct. It wants "C) Psychology focuses on genetic makeup, while sociology focuses on social interactions.", but that's not a true statement. Psychology is absolutely not focused on genetic makeup.

Would simulation games work here?

Just giving the students access to something that simulates a frictionless world to play around with? maybe with a simple on off switch.

Something i've probably seen shared by others here in webgl at some point and far cheaper to run than genai

Isn't this just showing the effects of actively engaging the learner by placing a topic in contexts familiar/favored by learner versus just reading about a topic? Like, if you had made the text pdf readers do some manual thinking by working on trying to place the topic into the same type of familiar/favored context, wouldn't that have been the better comparison? I think using GenAI for learning is cool and exciting (…

> I think using GenAI for learning is cool and exciting (especially for autodidacts)

I don't know. I've been trying, but I think there are two fundamental issues. First, I don't think it's all that useful for "out-of-order" learning and for explaining concepts in non-conventional ways.

To give you a practical example, there's a certain order in which we teach math, and every subsequent step builds on the previous one. But quite often, this order is just a matter of convention, not necessity. You can explain a ton of higher-math concepts in terms of high-school algebra and geometry, it's just not something we do because we don't intend to teach high-schoolers any of that, and for undergrads, it's more expedient to lean on their knowledge of calculus / mathematical analysis than to start by drawing triangles.

And not once have I succeeded in convincing an LLM to circumvent that. If a topic is explained using mathematical analysis in college textbooks, this is how it will always answer. Which actually sucks for that curious high-schooler.

But second, LLMs just aren't nearly as dependable as textbooks. It's not even the base error rate - I think they're 90%+ accurate on most run-of-the-mill scientific questions - but that once they make a confidently-sounding mistake and you try to drill down, they keep digging that hole and sending you more and more off track. It's amusing if you know the domain and can spot mistakes. It's a huge waste of time when trying to learn a new field.

It's precisely why vibe-coding is more useful to experienced developers who can immediately reject bad results.

Shameless plug but I made a similar tool called asXiv[1] which allows you to "ask" arXiv.org papers questions. It also recommends questions on initial load that can help understand or explore the paper, here's a demo[2] from the popular Attention Is All You Need paper. The code is all opensource[3], it uses the google 2.5 flash lite model to keep costs down (it's completely free atm), but that can be changed via env…

That looks interesting! I put your Show HN (https://news.ycombinator.com/item?id=45212535) in the second-chance pool (https://news.ycombinator.com/pool, explained at https://news.ycombinator.com/item?id=26998308), so it will get a random placement on HN's front page.

Earlier quoted context omitted.

I was thinking about that when I bought my pinenote - imagine Tom Riddle's diary helping you with mathematics. Sadly I lost interest in the Linux side of the pinenote as it took a while to get to a working state and now I've got other things going on.

> imagine Tom Riddle's diary helping you with mathematics. Your tone suggests that this wouldn’t be horrifying so I wonder what you meant by this.

Simply that it writes back and helps you along. hints might fade in after ten seconds of you staring at the problem.

I was referring to the visual experience, not the dark lord possessing people.

You may not be wrong that tactics aren't sufficiently widespread, but that's the thing they're just tactics.

Spaced-repetition is a good example. It's so objectively better than other forms of memorization, but it's just one tactic for learning.

In this sense "teaching well requires a specific set of tools and tactics" is exactly how "a good teacher can teach anything" would make sense.

The problem is it doesn't make sense.
