So I'm taking a storyboarding class at my college and we have a big project coming up. I've been working on it a lot and talked about the story with my professor and he seemed to really enjoy it. We're on week two of working on it and I've finished my treatment and have been working on the storyboards digitally at home. When I went to class, my friend who gets sick often was there (a rare occurrence even though she tries her hardest) and we chatted a bit at the beginning of class. The professor handed out a list of shots we should use in our story if we wanted. As I already had my shot list at home with my storyboards, I decided to help my friend since she didn't completely know what to do.
I was helping her develop her story and we decided to watch some videos on my computer for inspiration. The project theme was "Escape" so we were watching escape scenes from movies. The professor notices and comes over and I make a joke about how we're watching one of the best scenes in film history (it was a scene from Shrek with the princesses). He tells me to stop the video so I do, but at this point I can't tell if he's joking or not. I stop the video and he tells me to turn it off so I exit full screen and close the video. He then proceeds to ask me a question I don't hear (tight fitting mask plus my anxiety making my blood pound made it hard to hear). I ask him to repeat his question and he gets mad. He then asks me what the video has to do with my story and if I'm using it for my shot list. I explain to him, no, I'm helping my friend since I'm pretty much done with my project. Then he asks me something else, this time I didn't understand him at all and my anxiety was through the roof. The class by now is dead silent. I ask him to repeat his question and he takes my handout of shots he gave us earlier and rips it in half. He asked me what about the shots we talked about last week. This still confuses me because we didn't discuss shots. I told him about my story and that was it. He then asked how long we've been working on this project. I say "around two weeks" he said it's been longer than that (it really hasn't). Then he tells me if I don't tell him what shots I have I get a zero in class for the day. I said that I have my shot list at home but I can gladly go through the script with him and tell him what I remember I wrote down for that scene. He gets mad and rips the paper in half again.
At this point, he turns to another student and makes him read what he has so far for a shot list. Then other students. By now, my friend has gone to the bathroom because she started crying. She can't handle being yelled at.However, the teacher keeps going. One class member has less than I do, but he tells them good job. I keep working silently and decide to just copy down what I have on my computer at home onto my notebook so he won't blow a gasket again. I felt humiliated and angry, and I don't know what to do about it. My brother says I should go talk to the head of the department but I don't know if that's appropriate to do in this situation.
TL;DR: I was helping my friend in class and my professor thought I had done zero work, embarrassed me and my friend, yelled at us, threatened me with a 0, then humiliated me by using my classmates as "examples"
