Not that I know anything about curriculum/technique/etc. Just wondering, though, how one goes about teaching this. Do you organize it by specific punctuation mark? Like, do you teach the comma and all its uses, then, separately, the semicolon, then the colon, the apostrophe, whatever? Because I would think (this is theoretically speaking, of course, as my experience in language instruction is infinitesimal) that punctuation and the other particulars of language could be taught by instance. I mean, instead of saying, "Here's a punctuation mark, here's the structures in which it's used [insert example sentences]," saying "Here's what you're trying to say, here's how you would go about it [insert discussion of the role of the comma]."
This is just me musing about how to approach a task other than the one in which I'm presently engaged. I have a humongous article to edit for the school paper by tonight, and I'm stalling. Bleh. But, no, really, I'm extremely curious about this. I do still want to be a language teacher eventually.... Sorry. Not a helpful post for you. *goes crawling back to work*
