Since I took the time to read most of the messages that were posted, I hope members of this list won't mind my usual complaint. (If you do, use the delete button.)
     I was struck by Rebecca's description of how she has students use tape recorders, and by the praise for her approach sent in by other members of the list. My initial reaction is that what she is doing is irresponsible and unethical. She may, of course, be able to prove me wrong, but I would like to see the evidence. I don't believe that she can effectively provide her students with a good analytical grasp of sentence structure, no matter what textbook she uses, in a single semester while doing what she says she does.
     I note this in the context of Janet McClaskey's article in the September issue of English Journal. Although the article is not about grammar, McCloskey notes that two of her colleagues had been teaching students -- for twenty years-- that "because" is a coordinating conjunction. When one of the teachers looked it up, she was horrified by what she had been doing. McClasky claims that she can raise students test scores by, among other things, teaching them never to use a comma before "because." (The teachers who had considered "because" as a coordinating conjunction had been teaching their students to always put a comma before "because." )
       I'm sure that some members of this list will want to argue the question of test scores, and some may even claim that "because" IS a coordinating conjunction. My question, however, is this:

What evidence can those of you teaching teachers (and doing what Rebecca does) offer to show that students who pass your courses (future teachers) do indeed have a solid, conscious command of sentence structure? Among other things, will they know that a sentence such as "The plane crashed five miles from here, its tail pointed at the sky" is not a comma-splice? (Or will they mark such sentences in their students' writing as errors?)

Having taught future teachers (an entire semester devoted to grammar), it seems to me that many of you are having a great party, but it is all dessert and no meat, potatoes, and vegetables.

Just wondering.
