I understand getting into trouble for not listening when she is supposed to, but I don't know about being graded down for it. I bet if the teacher had asked her to summarize the video or repeat the poem she could have because she probably was listening - she was just messing with something (she shouldn't have been) at the same time. I also think what is rubbing me wrong is the wording the teacher used - "bad behavior in class". There are so many different ways to say that she was not paying attention when she should have been.
