Are funny teachers more effective?
This is an interesting study because most studies on this are correlational, this uses randomised controlled experiments.

Why do students keep using study strategies that don't work? (even when they know they don't.) A big takeaway from this study for me is the claim that if classrooms cue weak strategies, students will keep using them.

I can't be bothered with Christmas after my mum passed away unexpectedly & I had to empty her house of all those years of consumerism, I have zero interest in continuing to fill our house with stuff I don't need, I'm getting a skip to start clearing crap in the new year.

A common problem with learning, whether through apps or other methods, is the emphasis on completing tasks rather than providing ongoing formative feedback.

Excellent post from Mary. As @counsellc.bsky.social says, "You cannot Rosenshine your way into a curriculum, and nor can you Rosenshine your way into mediating content in subject sensitive ways."
I don’t think as much attention has been paid to implementing the curriculum as it has to the pedagogy to teach it.
It’s a bit like going into a restaurant where all the effort has gone in to making it look amazing...
