I started learn linear algebra and some mid-level math stuff couple of years back. While I really wanted to learn I still struggled to find a good learning path and use a product similar to Duolingo for math. Eventually I learned some, then stopped using it and then forgotten all of it. But my point is despite if me really want to learn I found it quite challenging to find learning path that I trusted to be good star…

3B1B are primarily math entertainment videos, they don't actually teach you anything.

They are good if you already know a subject well, and want a new perspective on the material though.

As a daily user of Anki and Math Academy, I'm very excited about how software can help us learn. Now, with AI, we can really build tools that were not possible before. I built for myself AlgoTutor[1], a CLI tool that teaches Go developers algorithmic skills and concurrency. The recent Understanding floating point[2] from Oz Nova is also a type of tutorial I want to see more often. [1] https://github.com/zuzuleinen/al…

I'd never heard of Math Academy. It seems interesting, but quite expensive ($49/month for software which is in beta). Would you say it's significantly superior to something like Khan Academy (which is free) to justify paying that much?

It is vastly superior to Khan. Had my kids go through both, so can compare.

That said, on higher levels there's some cruft that trains mechanical skills, and that's on subjects that are needed only in the scope of the US system. For Europeans these should be optional, alas they are not and this adds a lot of tedium and hassle to an otherwise rather frictionless process.

>Handwriting activates a broader network of brain regions involved in motor, sensory, and cognitive processing. Typing engages fewer neural circuits, resulting in more passive cognitive engagement. Yes, that's exactly what I mean. If I'm focusing on what my hands are doing I'm focusing less on the material proper than I'm trying to digest.

The idea is that focus and actually working all of your hand instead of just fingers helps learning the material more efficiently even if your own perception of it does not agree.

Maybe it works for some people, but it certainly doesn't for me. When I'm handwriting, especially in bulk, all I can think about it how much I hate it and how I can get it to end faster. I take fewer notes with more abbreviations that are later harder to decipher.

It's different if it's something like mathematical expressions, because those are never easier to type, but just regular sentences? Absolutely not.

May I ask why? If by "not the same" you meant: AI is not at the level of a good human educator, it is a fair argument - but not many humans can afford to have a one-to-one human educator either. Perhaps I am a bit more optimistic, but if AI could give me, let's say, 90% of an average lecturer's capability, at 10% of the price or even less, that is probably extremely valuable. (For one, I would certainly be interested…

In some ways an LLM tutor is better. Try getting a human tutor for things like Category Theory or Lean 4.

I believe if you need a human tutor to understand category theory or Lean then you don't have the requiste math/CS background, and a human/LLM tutor won't be able to meaningfully teach you anything.

Note I said "meaningfully" - something with LLMs that deeply concerns me is that they provide edutainment, and people actually think they're learning something. One of the comments on this thread mentioned giving a "dense linear algebra pdf" and having an LLM use the Socratic method. I guarantee they would have learned more if they read the PDF. I strongly doubt they learned anything at all with a bunch of silly "Socratic" questions about linear algebra. But it felt like they learned something!

"Conventional wisdom says AI will replace people. I believe the opposite." So people will replace AI?

Yes, it's a bit of an odd h1, website also looks very Claude-generated, but regardless, probably most people understand the intent.

You are partly correct.

They have training video series as well. Even one on Linear Algebra. Starts from scratch and works up to advanced.

Scorm is a zip file with html files to structure content any way you want with a minimal amount of mandatory standards. It was never meant for assessment, nor is it secure. The creator of scorm said to not use it learning had to be secured. It’s not a system or a framework in any meaningful or standardized sense, and more of a format for compiling content that can be copied between different places.

That's an oversimplification of what SCORM is, but point taken. My comment was about LMS.

It's not an oversimplification of it at all.

I just took the conceptualization of it away from the sufficient experience I have with LMS to do the same with it:

Learning management systems are rarely about learning. Too often, they're first about about managing learning for the learning manager, and teh priorities of the learning manager (maintaining compliance) and that's what the software and sales process aims for.

The learner, actually learning, or being a central focus is a second or third class citizen in such tools.

What an incredibly elitist thing to say.
