I dont think anyone would disagree with the notion you cant "force" anyone to be a good teacher....likewise, you cant "force" anyone to be a good skier.
But in addition to creating the right culture and opportunities, I think a key point is you can Inspire people to want to be great teachers.
Interestingly, I'd say that while you can't force someone to be a good teacher, you can provide them with the skills, knowledge, and partially, attitude to succeed. There are so many fundamental elements in good teaching which aren't even addressed in the level 1 or 2; a three or five day course could be enough to provide teaching fundamentals, nevermind any on-hill ski improvement. Again, this is my perspective coming from a corporate training and instructional design background, so take it with a grain of salt.
That makes one less wrong reason to teach. I believe there are instructors in the business for a few other wrong (or at least incomplete) reasons:
- Free season pass
- Free improvement sessions
- Money (ha!)
I actually think these perks are good additions to the main good reason to teach: for the joy of enabling development in others. But in isolation, they won't motivate a teacher to be successful.
And from what I've seen, the hotshots (and jerkfaces) become patrollers. (Good riddance!)
