Really? While reading I couldn't help but think about how I wish this article on writing well were... written well. That block quote loses me in the first sentence, I had to re-read it a few times.

"Good teaching requires alternating between two views, going up and down levels of detail. Sometimes you zoom out and give students one word for a big idea, calling a whole chain of events a "collapse." This 'Nomiinalization' lets them hold the idea in mind instead of the whole story. But summary words alone can lose students, the abstract loses meaning as details are forgotten. So you zoom back in with examples, stories, pictures, concrete cases. Those reinforce the idea of the summary word."
