Retrieval practice is a powerful tool but it's often used in ways that are not supported by the evidence. Here are five principles to think about when trying to avoid lethal mutations and apply it more effectively. open.substack.com/pub/carlhend...

We can't fit in any more than 700 people so, more than a month out from researchED Ballarat, we are sadly sold out.
Experience shows that some people who have bought tickets will experience circumstances that mean they can't attend, so it's still worth registering for the waiting list.

Does retrieval practice still beat restudy when the exam really matters? In authentic high-stakes exam preparation, testing only improves later performance when it includes feedback, and even then it is no better than focused restudy in the short term. www.tandfonline.com/doi/pdf/10.1...

But deep understanding is not embarrassingly parallel. It is painstakingly serial: built connection by connection, layer by layer, in a process that requires time, sequence, and the kind of integrative thinking that no algorithm yet replicates."
On the difference between learning that scales and learning that doesn't, and what a concept from computer science can teach us about where educational technology succeeds and where it reliably fails. carlhendrick.substack.com/p/the-embarr...
Mastered But Not Understood: Why Learning Doesn’t Scale the Way We Think It Does

What is the number 1 thing schools are getting wrong in applying the science of learning? For me it's retrieval practice and this post attempts to say why: substacktools.com/sharex/5L00N...

A new low. Absolutely appalling.
This is overt racism. Full stop. There’s no ‘misinterpretation’ and no excuse. This is who he is, who he’s always been, and why he should never be anywhere near power again. And there’s a reason the tapes from The Apprentice have never been released.

It is not a tax rise; the interest rate has absolutely nothing to do with what you repay; the fact that MPs and other higher paid grads are paying back more is the entire point of the system; I beg of you to stop getting student loans wrong
