Personally, I find the whole thing deeply insulting.
For all the thousands of years of human existence, teaching has meant one thing, and one thing alone.
For a few years, a bunch of hippies told us that "teaching" meant the exact opposite of that, and that we couldn't do that thing that used to be called teaching. We went through the motions of their BS while they were looking, and taught our kids the right way when they weren't.
Now, they've rediscovered teaching, think they need a new term for it, and my district thinks I need to attend a week's worth of in-services to know how to do it.
I've got two words for the whole educational theory crowd, and they ain't gonna like the first one.
