I taught a class of eight students who liked each other and got along well (but weren’t dating each other) for twenty hours a week for six weeks. They were all still terrified to give presentations at the end, even though it was a language course and they all already spoke a lot in class. I don’t know how I could make it easier for them, because that’s just about the lowest stress scenario I can set up. I’m not judging them for it, because I had a couple moments of panic in front of them as well, sometimes it happens, but I’d like to make it less stressful. I could just have them do it every day to make it routine, but if some of them are really affected by it, that might just make them dread the class.
