Coaching sport is the most common form of having a teachable point of view.

Every one has a different way of playing the same game and the coach has to teach the players how he wants them to play the game his way when they, the players have a different mind set of how the game is played. So the coach has to develop a teachable point of view, to get his way of playing across to the players.

"Cultivating idea stake holders" is a good term to look up on Google. This deals with the whole process of finding outcomes for teachable points of views.

I looked at the article and I thought it was ok. I thought Kirendall also had some good information, and this is the foundation of a teachable point of view, That all points of view can be taught if you provide the right steps to take in the learning process of what it is you want to teach.
Example: I taught a no-English speaker to pass his English Exam in 3 months with a 5 in all 4 disciplines by only learning for 3 days a week. I wanted to show other teachers, my point of view about teaching was teachable.
