In space, water doesn’t behave the way you expect. In microgravity, there’s no gravity pulling it down—so surface tension takes over. Instead of dripping or flowing, water sticks together and clings to surfaces, even forming a floating layer around your hands. This is why astronauts can’t use normal sinks or showers. Water doesn’t fall away—it has to be carefully controlled and collected. This iconic experiment by Chris Hadfield shows just how strange everyday physics becomes in space. Credit: NASA / ESA

Teachers and students are already using GenAI across the globe. But is education improving? The new Digital Education Outlook assesses the latest evidence from international data. What is known about GenAI's impact on learning, creativity and teaching? oecd.org/en/publications/oec…

I think a subtle but very real element of a teacher’s behaviour management craft is the capacity to maintain boundaries by noticing issues and communicating botheredness: a firm/kind/adult tone of voice; body language, facial expressions that say, with conviction, ‘no’, ‘that’s unacceptable’. It’s calm, deliberate, assertive. Can be warm or a bit stern or even cross if needed. But you need it, whatever the backup system is. Students should know that you’re going to be bothered about boundaries. Your personal disapproval should matter to them / it nearly always does! When kids say ‘you don’t mess with Ms Smith’ it’s because she’ll notice, she’s bothered and makes that absolutely clear - in the nicest possible way. I think this needs more explicit discussion and modelling in PD so it’s not seen as an ephemeral magic beans thing. I have met many ECTs who have this sorted already - but others need a ton of support. Sometimes it’s the noticing; sometimes it’s communicating the botheredness. It should be normal to discuss these things.

This is glorious.
