In comment #9, Post blogger Cari Shurman tells how she pioneered Tai Chi to to train teachers to help kids calm down and concentrate better. “I have ben a teacher for over 30 years. When I decided to offer Tai Chi in the schools I wanted to train teachers so that they can use the movements in the classroom before tests to calm the kids down and get oxygen flowing to their brains to concentrate better. I also wanted them to be able to use it to help ADD and ADHD kids, to give focus to a discussion on bullying, to calm kids down who are feeling hyper. So I decided I needed to simplify Tai Chi so a teacher could learn it quickly and use it easily in the classroom.”
