What they believe
-
Claims that a method helps children learn several times faster are meaningless without specifying what they are learning faster.
the right follow-up question whenever anyone claims they can help kids learn 2x, 5x, or 10x faster is "learn what?"

Excessive enthusiasm for education technology tends to emerge where a tech company's spare cash meets a school system's tight budget.
Edtech psychosis flourishes wherever a giant tech company's free cash flow meets education's threadbare operating budgets.

Their words
The public can debate those goals, of course, but they require resources, chief among them time. Doing more stuff generally requires more time. One weird trick for saving time, more and more parents are learning, is to commit to fewer goals.

Your Kids Can Learn 10x Less in 10x Less Time! Said 16 Sept 2026
Learning faster than normal in education usually means covering fewer or shallower goals, not learning more efficiently.
The public can debate those goals, of course, but they require resources, chief among them time. Doing more stuff generally requires more time. One weird trick for saving time, more and more parents are learning, is to commit to fewer goals.

My Screen-Free Summer School Class Said 24 Jun 2026
Students mostly use generative AI to cheat, disconnecting the artifacts of learning like essays and grades from actual learning.
Kids are using generative AI a lot. And they're using it to cheat. Or if you prefer more nuance: they're using it to disintermediate the artifacts of learning (essays, answers, grades, etc) from learning itself.
My Screen-Free Summer School Class Said 24 Jun 2026
Generative AI has failed to produce the learning gains it was promised to deliver and instead shows evidence of harming learning.
A thing got invented and its existence in the world-without denying any of its affordances-has not only failed to produce the learning gains promised by so many and instead produces evidence of negative transformation weekly.
My Screen-Free Summer School Class Said 24 Jun 2026
Peer relationships, not academic content, are the main reason students tolerate attending school.
We also know that if you ask students "why do you put up with school?" the vast majority of them will say, "Because it's where my friends are."
Everyone in Edtech Should Show Their Cards Said 27 May 2026
Most students benefit more from the motivation, accountability, and support of teachers than from unsupervised self-directed learning tools.
But most students benefit enormously from the motivation, accountability, and support they receive from their teachers.
Everyone in Edtech Should Show Their Cards Said 27 May 2026
When students know a teacher cannot easily monitor their work, they conclude the work doesn't matter and disengage from it.
Kids know that teachers can't easily check up on them. They come to realize their work doesn't matter and react accordingly: drifting off task, onto other tabs, and out of any state parents would recognize as "learning."

What is a korrent?
A korrent is a belief a person has stated in their own words: one sentence stating the claim, backed by a quote and a source, kept at korrents.com.
Under a name here, the quoted block is what they actually said. The korrent beneath it is the claim those words support, in korrents' wording — tap it to see the record, its source, and who else holds it.
Nobody here wrote their own korrents. They are compiled from public statements, and a person can change their mind, which is recorded too.
