How do I get this girl to listen to me while I give a lesson?
Today was my first day as the new instructor in this dance studio, and everyone was respectful to me except this one girl. She was constantly talking while I was trying to teach everyone, she stopped in the middle of a lesson to answer her phone, and she was even changing the choreography! I can understand why somebody might be cranky because our lessons start really early in the morning...but the way she was acting was just rude. I really need her to pay attention while I teach so she doesn't hold back the class, we also have a dance competition coming up in a few months and today my dancers learned nothing because of her. How can I get her to pay attention? I also don't want to be rude because she is 3 years older than me....Today was the most stressful first day I've had and I'm afraid that her behavior will just get worse. What can I do to get her to pay attention and participate better....?
