Re: Teaching .... I have a question.
Years and years ago a group I was with had a promotion board of examiners who had a list of skills and a grading scale with 3.0 to 5 passing criteria. I always felt it was wrong because the examiners, of course, had different values. I prefer having instructors and teachers having the responsibility of promoting to within two levels of their own. Mistakes show themselves for sure, and then learning takes place relatively quickly in our small group. I've understood for a long time that the only way we learn is by doing it and paying attention. The "right and wrong" of it will work itself out. If not, it's hopeless anyway.
