My memory is that this sort of thing was also covered fairly extensively in Eng. Lit GCE, but I've never taught that and my experience of it is long ago. Anyway, I spent most of my Eng Lit classes reading non-official books under the desk so maybe I'm wrong.

I just feel that although I had a reasonably good education that covered this area, it left me hopelessly naive about communications via 'official' channels. I learned about those from experience, not lessons. It may be that other people are better at absorbing concepts that they are being deliberately taught than I am, of course. I'm crap at that. Let me try it and break it, that's how I learn!
