...an element is anything that needs to be learned or processed and the interactivity relates to how reliant one element is on other elements for comprehension.
I was first introduced to working memory by [Ramsey Musallam](https://twitter.com/ramusallam) and I've pulled it out every now and then in workshops with teachers. The idea is easy to grasp, but hard to put into specific practice when planning.
I'd never heard of "element interactivity" either, but this is - hands down - one of the _most_ approachable descriptions of how to adjust planning and instruction to account for cognitive limitations with novel or complex material.
