I mentioned about the teaching scenes here many times already.
It all made perfect sense when I went through the process of getting a cert in a specific (jumping related) sport here in HK. Basically, they have these masters degree guys teach you half the course in different aspects of sports science (I recognize they're merely ripping off slides from their own prof), and the other half, with a guy who pretends to teach you, but since he needed to build relation with the seniors, he doesn't actually have the time to teach us. By the end of 3 months, you do a written test from the guys there who basically gives you 80% of the answers. And a 2 minutes 'test' just to get things over with. Congratulations. you've become a 'coach'.
As I have a frame of reference to compare, they really left me feeling like i know sh*t. Half the people who also got the cert have never done the sport before while the other half who does the sport for many years still messes up the basics when performing. Out of 20, there's only like 2 whom I can say is qualified to take the teaching course as they're able to perform it. Not even I should be there IMO.
The guy who was teaching us actually had good intent and thought he wasn't able to really cover much in 3 months, so he made a DVD, recorded all the students he has had and the practices they do, and was about to hand it to us students. Then what happens? The top guy who brought together the course who partners with the HK government, intervened and kept the DVD for himself. He said he has to copyright it for himself as the course was set up by him.
So if you want access to watch the DVD, you have to have good relation with the top guy. Can't bring it home to copy can't do anything. If you want access, you gotta listen to what they say.
