Ever since I was a graduate student, I've been known as an even-tempered instructor. That's something I've taken pride in. That changed today when I blew up at a student.
I gave him a dressing-down after class because he'd been habitually tardy, absent, or on his phone the entire semester. This particular student is one of my cheaters. He had the gall to show up 15 minutes late today, play with his phone the whole time, and then try to sign the attendance sheet at the end. When I asked him what was going on he said he just "hadn't been feeling it today, y'know what I'm sayin'?" That's when I full on shouted at him. I snapped for a few seconds before regaining my composure, which I feel kinda bad about. On the other hand, I probably scared him straight for the rest of the semester.
