I have learned more about teaching Tai Chi from reading the following book by Dr. Paul Lam and Maureen Miller:
Teaching Tai Chi Effectively. By Paul Lam, M.D. and Maureen Miller. Tai Chi Productions, Narwee, Australia, 2nd Edition, 2011. Index, 225 pages. ISBN: 098035739X. "Simple and Proven Methods to Make Tai Chi Accessible to Everyone." VSCL.
One challenge I face when teaching at the fitness center is that I have complete beginners, intermediate students, and advanced students all attending the same two classes together. I teach too quickly for the beginners, and get into too much step-by-step detail for the advanced students. I need to figure out a better way of dealing with this challenge.
I need to be silent more often. Students are really not interested in stories and facts about the history of Tai Chi. I ramble a bit much.
I've been better about giving more breaks to allow students to rest and get a drink.
I'll ask for input and questions from my students more often.
