🚨Incredibly excited to announce this job 🚨

Are you interested in driving the future of professional development? Helping teachers everywhere get better faster?

We changed the game on retrieval practice, we're going to do it on CPD.

Two adjacent dippers produce circular wavefronts that produce an interferance pattern showing regions of constructive and destructive interference.

We have a lovely class set of little ripple tanks that allow them to play around and observe wave behaviour

Even though they say 'I don't need to use that' when I introduce 'squashy cos', by the end of the year they all use squashy cos to find components.

I go for the coscrodile’s jaws are around the angle!

Day 23 - As I sit untangling my daughters Newton's cradle (!!!!) I need something relaxing and mindless to accompany the infuriating task. Luckily I have this video of a giant pendulum wave with notes for each swing.

Well now I feel old. I get sry is sorry but what is nvm? 🤣

/s means a post is sarcastic.

I like this one as a predict, observe and explain exercise to hammer home force on a current in a magnetic field and Fleming’s Left Hand Rule.

But audio cassettes are back on sale now so I’m not sure this will be any time soon.

But isn’t the speed of light invariant 😉 Also there are materials with a higher refractive index.

Little do they know, you are the OG.

I’ve turned up some real gems from @helenrey.bsky.social’s spreadsheets. A really great resource when first planning or refining your teaching of a topic.

Also although this sounds ridiculous, cover it in delicate glass baubles.

It looks like you are beyond the easy solution (don’t have a Christmas tree and cats in the same house), Can I advise a water pistol?

😉 I guessed something like that/the.

How do you service your VdG? New belt? Is there more to it? Ours aren’t working that well. The belt speed seems quite variable even with new belts. Might we need to replace motors or brushes?

Wow, a lot of hard work has obviously gone into this and it features so many great ideas explained really well with links and videos. If you want new ideas for teaching magnetism from KS3-5 this has plenty.

Don't know whose this is, but it's up there for the best physics meme ever.

How do you define ethnically British and what would you like to be done to make it ethnically British again?

Just some thick, bare copper. Don’t know the swg I’m afraid but I suspect the thicker the better.

Here it is going in circles, with a bit of help!

Depends a lot on the framing and impact.
There's a lot to be said for lay noticing/questioning (I saw this... what's the thinking?)
One of the problems with lesson observation is that we have entangled observing and evaluating, and then put a lot of weight on those evaluations.

I like this a lot. Non judgemental observations are really useful feedback. Direct suggestions probably require someone with significant domain knowledge to be useful and instructive.

Here’s another hypothetical. You are a tailor with training and experience of measuring people and carefully stitching together fitted clothes. If someone who hadn’t ever sewn anything came and made suggestions of how to do your job better how would you value their feedback?

Rejecting advice and feedback out of hand is not great, but questioning feedback because the provider doesn’t have sufficient understanding and insight to give useful feedback seems very sensible to me.

I’d listen to their feedback and potentially respond to it but on the whole I suspect I’d be fairly sceptical.

Here it is going in circles, with a bit of help!

A couple of students in my enrichment group have made a nice linear motor. #iteachphysics #chatphysics

Thanks Michael 😀
