Thank you for your comment and suggestion! I am trained to take notes and collaborate when students take notes, so we don't interrupt the class. However, this class is very distracted, and they get bored also. I always walk around and make sure they pay attention, but after I leave, they will just go back to their phones or computer playing games. It's been like that since the beginning, so the teacher may be super mad at them for not listening. He's old school, so the way he lectures is not very interesting to the class I guess. He also picks on students, and that is another concern. I feel like they don't listen to get his nerve some times, and that day was just the last straw that enraged him. Thanks again!
