The first thing I would advise is to have her work on "front foot steering" The best way to get someone to feel this concept is to go to a super mellow slope and ride it one footed.
I've made both my friends do this when I taught them. Hiked the bottom of the shallow hill and began one footed heel and toeside stops. Both of them had heel/toeside turns their first day! Glad you make me feel like I've done something right anyway.. off subject.
