This is very interesting to me as I have been asked to teach a couple of classes at my LQS. I have make a supply list for each class. I have to make sure I understand what I want them to do. I was a hair dresser years ago and I can learn best by seeing and doing it as we go along. If a person can repeat the instructions out loud, they are expressing to me that they know what I have asked them to do. This is what I do when teaching little people. I show them, they do it as I watch and by that point even the weaker student has a better idea. I would ask her to come and sit in the next time you are teaching.
