What I would hope gets added to the general discussion around education before I retire is this:

Education is, in general, suspicious about research. And it's EASY to go slow and be cautious about something you're already suspicious about.

What's HARD is to apply this rationality and skepticism to things that everyone loves but have little evidence base (or run counter to evidence). Actually, it's not even hard to be skeptical of those things--it's hard to be publicly skeptical of those things and stand by your own thinking.

What is it about maths that makes people demand that every individual skill needs to have some mundane, everyday use? We don’t do that with other subjects. Nobody goes into a primary school class, observes a session of clay modelling and exclaims, “But when will students need to be able to do this at the supermarket!?”

“But, can’t you just add 0.00000000(loads of 0s)00001 to make it up to 1? Then it’s just a bit less.” That one I like, I show them what we add to numbers to make 1. To 0.9 we add 0.1, to 0.99 we add 0.01, to 0.999 we add 0.001, and so on, so to 0.9999999999… we add 0.0000000000…, and if the 9s never end then the 0s never end, so we are adding 0.
