Maybe it is a matter of how the coach is giving corrections? Are they giving one or two at a time, or a whole litany? Maybe your daughter and coach could pick one thing at a time that they are concentrating on when it comes to form.
If she is feeling anxious at practice, that can greatly interfere with the ability to focus.
I would suggest help her get some perspective so she can lighten up and take the pressure off herself. So she forgot to point her toes on that one. Did she tighten her butt? Good! Try to help her understand that all the girls have things they struggle with that she probably has no idea about. Gymnastics is a hard sport! It will probably help if she can learn to not compare herself to the others too much.
I think it just takes time to get to the point that the muscles do the remembering for you. She is probably really in her head at practice, which is to some extent normal while one is learning something new. It just takes time for it to all sink in.
So here is my specific idea: If it is a matter of needing more practice in remembering exactly what to do to have correct form on the skill, here is a memorization trick I learned when I was an actor for memorizing lines and blocking (stage directions.) My boys have found this technique helpful when needing to remember their gymnastics routines. Conceivably it can work for anything.
Right before going to sleep, relax and calmly think about what needs to be remembered. Like when she is lying in bed. If she is feeling too overwhelmed trying to carry it all in her head, she could try writing down each of the things she wants to help herself remember. Then she can read it (or just remember it.) She can say it out loud or in her head, or you could read it to her while she closes her eyes and visualizes. She could try actually squeezing and pointing in bed as long as she is able to do that without getting too wired to fall asleep. There is no right or wrong way to do this, she can experiment, but the main point is that when this is done shortly before falling asleep, the mind does some heavy lifting of memorizing during sleep.
One of the things I learned when helping my son with his anxiety over schoolwork is that new concepts need to be learned, forgotten, and relearned multiple times before they are truly well absorbed. So when we forget things, that is actually part of the learning process. Forgetting is good!
