Hi. I work in K-12 education....schoolteacher training. Lots of published research says that older teachers don't improve much. Well, I'm "older." Just turned 50. In 2020, I'm trying something new (improving at golf) to learn about adult performance change. By experiencing frustration, and experiencing the coaching techniques, practice techniques, and feedback tools in the golf sector, maybe I can come up with new ideas for K-12 teacher improvement, particularly older ones more set in their ways.
