Now, for the sake of discussion, I will answer my own questions with my opinions. Please feel free to share your opinions, though.
Initially, I learned to teach from observing my teacher. He never gave alot of lessons on how to teach and, as far as I know, neither did anyone in the USSBDMDK federation in which we used to belong.
When I finally finished my undergrad and took the classes for my teacher's license, I learned alot more about education, including things like child development, learning styles, intelligence, physiologic/motor/kinesthetic development and general teaching methods.
All of this was expanded upon when I completed my Master's degree. And I also learned new things like how to measure my own success as a teacher and how to structure curriculum in order to mean my pragmatic and philosophic goals.
Now I can safely say that this education has far more influence on how I teach then what my teacher did.
Via experiment. When I changed things about my approach to teaching, I made many attempts to compare with what I had been doing and with past results. If "tradition" ended up producing better results, then it stayed as part of my pedegogy. If it did not, then it was removed. The key here, IMHO is that I looked at teaching as a progression to my goals and less as a means to pass on tradition.
This may be controversial, but in my experience most martial arts teachers that I have met could really benefit from some formal education in education. There are alot of things ranging from structuring a curriculum to lesson planning to teaching methods and to understanding developmental appropriateness that I think all martial arts teachers could benefit from. Most martial arts teachers never have exposure to this material and although some figure all of this stuff out via trial and error, most do not. This, IMHO, would go a long way in improving the overall quality of a martial art offered by various organizations and/or schools.
Here is another question related to the last one...does your org provide this training? If so, where did it come from?
