This is a very typical DBSF, arm-powered swing by a very young player. I've seen this more times than I can count. I would approach this by helping the player learn how to power the bat with their body, and get them to take their arms out of it.
I would start by having her rest the barrel of her bat on her shoulder and instruct her to hit the ball by turning her body and using her hands to turn the bat to the ball, rather than swinging her arms around a (mostly) stationary body. At her age, keep it simple. Use building blocks that can be refined later.
