Now I am no longer preparing students for GCSEs in Year 10/11, working in the French system, I find it so liberating writing assessments. No need to use past paper questions and I can develop interesting tasks which will really allow me to assess the student mathematically. Like this one.

Are there plans to add to this for even more curriculum coverage? What's here already looks great

Really cool (and somewhat freighting) work on Gen AI use and highschool performance in China. Homework Scores rocket up, time spend doing homework collapses, then predictably exam scores are way down. Results show bimodal response ~75% see scores drop, the other 20-25% keep doing the work.

I despair of the media framing on this. Surely the question is this: Two parties you may need to govern have proposed tax resets that leave most kiwis paying less tax provided the wealthiest pay their fair share. Why would you oppose that if yout goal is to help hard working kiwi families? #nzpol

Guess what I was thinking when I wrote this question is the standard approach with NCEA probability exam questions here in New Zealand sadly. It drives me crazy every year. How about we have questions in plain English so students can show their understanding of the subject?

If my student already uses the grid/area to multiply or factorise, I’ll use this. I do like that the product of the diagonals is always the same. That’s fun.

One of the coolest math facts that I know is that the only circle that fits perfectly in a 3-4-5 right triangle has an area of pi. Here's how we can prove this.

IRT sounds very much like the grading system we currently have in NZ, with achieved, merit and excellence questions and responses. Sadly it looks like we're getting rid of this for A-E percentage grading.

It really doesn’t. Plato had a great answer to this problem more than two millennia ago. In the Theaetetus, he describes memory not as a storehouse or filing cabinet, but as a birdcage. Imagine, he says, that each of us has a cage in our minds filled with birds. 1/

I keep coming back to this. Just such a fundamental failure of everything that has been claimed about a "knowledge rich" curriculum. Teachers are demanded to have higher standards but this slop is what they put out as their big rewrite.

In #MathsToday we played this. A sneaky way to squeeze in some revision on multiples and lots of fun.

A grid from 1 to 36.

Each player starts with 10 counters.

Players take turns to roll a dice and place a counter
on a multiple of that number if possible.
The first player to use up all their counters wins!

Weaker students can struggle with that, though, but a little tree helped. Cue maths teachers saying "I've always done it that way!" That's why you need subject specialists! 2/2
