Educational research is a bit of an anomaly, in that it has the lowest replication study rate of any “real” scientific discipline. There are lots of reasons for that, but it means that you can cherry pick individual studies to support just about any pedagogical (teaching) practice.
That said, the evidence is pretty clear that there is higher retention for most learners when writing by hand. Even writing with a stylus on the screen seems to lead to lower retention. There’s something about the multisensory input learners get from pencil and paper that seems to make a difference.
That said, that doesn’t mean there’s no places for Ed tech. In particular, students learn how to write better when they can edit their text, which happens a lot faster with a word processor. Digital science labs allow for quick exploration of a topic in minutes instead of needing a full class period for setup and clean up.
But it should only be used when appropriate, imho as a K-12 educator and parent.









AI companies have only pre-bought future years’ supplies for memory so long as they can make their payments.
OpenAI is losing $1MM USD about every 30 minutes, iirc. How can they afford their $1.4T USD expansion plans to 2030 when they’re bleeding that kind of cashflow?
A year ago, Altman was saying ChatGPT will never have ads, but they’ve already started adding them.
They have no “moat”—just about anyone can run a LLM with open models right now, and big players (Meta, Google, and others) are directly competing already.
All of these companies are facing massive potential legal judgements, too.
There’s no realistic path to profitability for OpenAI. OpenAI’s publications call for them, on their own, accounting for 2% of US GDP by 2030. Insanity.
So, here’s the point for PC gamers: the AI crash is coming, and hardware prices are going to come crashing down once datacentres are no longer able to afford to pay for the chips they ordered.
(Of course, server parts can’t be swapped to consumer hardware, but they’ll retool to meet demand ASAP since there will be strong pricing incentives to pivot back to consumer hardware quicker than the competition.)
