Cognitive Load Theory is one of the most useful frameworks in education. It tells us that working memory is limited, that extraneous complexity impedes learning, that beginners and experts have different instructional needs.
All of that is true.
But it's only ¼ of the story.🧵
Next year we're producing laminated class sets of these help sheets I've made to support our weakest students. They'll be able to use dry wipe pens and use them to support their thinking.

Maths teachers have introduced negative numbers for centuries, to millions of children, with a mountain of cognitive science to hand — and still can't agree how to do it. Debt, a thermometer, a number line you walk along. The arguments are detailed, sincere, and unresolved.

A Maths game featuring:
- two-player and single-player modes
- 50+ topics across KS3-KS5
Playing with coins led me to triangular numbers, with cuisenaire rods to number bonds and square numbers, with arrays of objects to factors, multiples and primes, with calculators to negative and imaginary numbers, with scales to algebra, with squared paper to square roots.
Enquiry learning is too big a label for this to be true-in maths it's possible to set up situations where pupils make their own discoveries that fill them with a sense of wonder-if this can happen it's important to give all pupils this opportunity. Teaching is a balance🤔😃
My dad wouldn’t buy me a lot of stuff, but he had a policy of buying me unlimited books, given I read the ones I already owned. I’m keeping the same policy amid this insane uptick in reading currently taking place at the Groshell household.
