I'm going to take a stab and say she's not comfortable doing it because she doesn't know what she's doing. And she's afraid to ask for tips. I've been there at one point when I was younger. But with some coaxing and letting her know what she's doing right MUCH MORE OFTEN than what she's not doing right (saying 'no' while she's learning is pretty much like a knife in the heart,) just might get her more interested.
