The point about dictionary is an important one. When I teach I try to keep redefining the words I'm using over and over again, even if I've defined them already. I feel this is one of the more underestimated complications. Especially in my math classes I've always found that teachers are all too eager to just write down some definitions and use them from then on, spewing out theorems that involve them and expecting people to follow. The dictionary takes time to sink in, at least it's always been the case for me.

I am also worried about the analogies and how they're all slightly wrong. I usually resort to trying to explain exactly what the computer does in completely reductionist terms on the bit level when you write an assignment, print, etc, but it's a bit of a rabbit hole and finding the right balance is hard.
