Nope. When I taught high school social studies, the only class the seniors had to take in 12th grade was American Government, and I taught all those courses at the local public high school. For awhile it seemed I was being too hard. Eventually I dumbed it down to where a third of the grade was seat time, a third was just turning in homework without it even having to be correct (just had to have a name and some scribbles), and a third was test scores. It should have been impossible to fail. But some kids still failed. At that point I got tired of dumbing things down, and upped the standards. The next term I told them they'd have six unit tests and a comprehensive final. Their grade would be based solely on test scores. They could come to class, and I'd be glad. They could do homework, and I'd comment on it, but only test scores would determine their grade. And scoring was from points possible, not from the highest score earned. Their first unit test was over a hundred questions. Almost none of it was memorize and regurgitate, it was mostly all application of concepts. Took me a long time to draft that test. If someone wanted to retake a test, they could, although then it became an essay test. I was worried there would be many class fails. But after that unit one test shocked them, they buckled down and there were actually fewer failures than under my dumbed down system. And a lot more learning/understanding. You know things are going well when a student launches into questions about how to merge features of an open and closed primary election, and suggests better ways to do things from out of their own head, without even having been asked to do so. Anyway, that's public school.
Now, that may seem off topic. But as I think back over my scuba classes and relate the two experiences, the scuba classes I took were all kind of like how I was functioning as a teacher at the most dumbed down level. None were at the higher level. Maybe one of the instructors in my scuba classes wasn't in there wasn't pencil whipping people through the scuba classes, but that would be pretty unusual.
