Re: Training the trainer
"English language O-level, we had a "teacher" who was borderline-illiterate"
My GCSE IT teacher knew barely enough about computers (and bearing in mind we're talking about BBC micros here, so nothing terribly complex to deal with) to cope with the practical sessions during our course, and wasn't all that much better on the theoretical side of things either. When you're having to explain to your teacher how to load something from floppy disc, it sets the bar pretty low in terms of what you expect them to be able to teach you in return.
That I still ended up getting an A grade (back in the days before all these newfangled starred grades came along to confuddle matters somewhat) says as much about how relatively easy most GCSE subjects were as it does about how much I already knew about the subject...
