M.,
I have a seven year old son who has some of these same problems. He's frequently afraid to try new things partially because of an unfamiliar setting, new kids, new requirements and the feeling that he might not do things perfectly. We have had numerous talks about trying new things doesn't mean he should know how to do them and be perfect at them. That it is about learning new things and making mistakes was part of how he would learn these things. We have also tried to make him comfortable with a new setting by taking him there in advance, with new teachers/coaches etc. my introducing him in advance. Where possible, we try to sign him up with a buddy he already knows. Maybe you could even sign her up for a private lesson or two before the class starts to build her confidence in what is expected of her. Good Luck.
