This is why I think AI chatbots have so much potential for education. Every student can have extended dialogue about the topic and really exercise those neurons.

I think the widespread use of that for education would have precisely the opposite outcome that you'd want. Nothing sinks in to anyones brain because they're not actually talking about it and they don't need to actually learn it for any reason in school because they can just ask the chatbot again at any moment.

Technological progress requires that we adapt education at the same time. We can still teach the ability to reason through problems when necessary, but still utilize technology when useful

I wonder if having offloaded arithmetic to calculators has led to a society that can't do math in their head well enough to make good choices at the supermarket or in other daily situations where simple math would be useful but the situation is too casual to pull out your calculator.

But the impact of that is tiny compared to the prospect of future generations offloading their general ideation and critical thinking to machines instead of just number crunching.

I tried for a few minutes to find the HN thread where somebody refuted the "handwriting is better than typing" for fact recall claim.

OTOH, IIRC,

- EEG measures brain activation. It takes more of the brain to hand write than to type, and so it is unsurprising that there is more activation during a writing by hand activity than during a typing activity.

- Do brain connectivity or neural activation correspond to favorable outcomes?

- Synaptic pruning eliminates connectivity in the brain; and that is presumably advantageous.

- Hyperconnectivity may be regarded as a disadvantage in discussions of neurodiversity. Witness recall from a network with intentional hyperconnectivity; too distracted by spurious activations?

- That's a test of dumb recall, which is a test of trivia retention.

- Is rote memorization the pinnacle of learning? To foster creative thinking and critical thinking, is trivia recall optimization ideal?

- (Isn't it necessary to forget so much of what we've been taught in order to succeed.)

- Is spaced repetition as or more effective than hand writing at increasing recall compared to passively listening?

- With persons who have injury and/or disability that prevents them from handwriting, do they have adaptations that enable them to succeed despite "having to" type instead?

- We don't hand write software; though some schools teach coding with pen and paper (and that somewhat reduces cheating, which confounds variance in success and retention).

- We write tests for software; we can't efficiently automatedly test software for quality and correctness unless the code is typed.

- Does anything ever grade, confirm, reject, or validate handwritten notes?

- Are there studies of this that measure recall after typing, and then after handwriting, too?

Edit: A, measure, B, measure; AND: B, measure, A, measure

There aren’t any information in this study about if there were any touch typists. This would be an interesting variable to test for.

The typewriting participants were explicitly not touch typing - they were instructed to... type with a single index finger... > participants were instructed to either (a) write in cursive with their right hand the presented word with a digital pen directly on the screen, or (b) type the presented word using the right index finger on the keyboard.

still people who are touch typists are able to find the characters faster on the keyboard than others. this message is written that way to test that out, in parts where it was possible.

however, in my case the blank keycaps did make the task a bit more difficult. i would write faster in cursive, and it might feel less effort.

also the reason was outlined:

> Allowing the use of (the fingers of) both hands would cause many unforeseen effects on the brain, which would make it hard to interpret the results.

btw, this post was quite frustrating to write.

If there is a good reason to, yes. To chase the latest trends (which is what all this EduLLM talk is all about) then definitely not.

I think it's actually the opposite - most people can't touch type, so they spend more time and concentration trying to type, which means less focus on the actual content. I would think that handwriting is more muscle memory for most people, thus they can focus more on what they're writing, making connections to it, etc.

I didn't read the paper but does this mean if one learns to touch type then there's no difference?

I think the difference in pressure holding the pen or pencil and the dexterity required to form letters still activates way more of the brain than simple touch type would.

That might not be enough without any assessment of the subject's typing skill. Touch typists have effectively memorized the keyboard layout and would need less effort to find the key to type, even if limited to one finger at a time

Looks like this did this because "allowing the use of (the fingers of) both hands would cause many unforeseen effects on the brain, which would make it hard to interpret the results," since handwriting is done with one hemisphere.

Still weird.

You would have found it, had you written it down.

Kidding aside, is this the one? https://news.ycombinator.com/item?id=42288545
