So, I'm a first year physics grad student who's absolutely miserable in these grad classes. However, being a teaching assistant and running my own lab sections is my absolute favorite part of my week. I actively look forward to getting in front of the class and helping the students. I was a tutor for 3 semesters in undergrad, as well as a grader for 3 semesters and a lab assistant for a semester (some overlap there), and I enjoyed all of that as well. It was initially my intention to get my Ph.D and become a professor, but the key point in that goal was I'd be teaching. It occurs to me I don't need a Ph.D to teach. There was a high school teacher at my undergrad university that kept trying to recruit me (and others) to consider teaching high school. He says it's tons of fun. Well, I've decided that I'm going to refocus my efforts on becoming a high school teacher. It occurs to me that I just enjoy teaching, and I'm hoping there's not a huge difference between teaching these 19 year old kids and teaching ~15-17 year old kids. So, I just paid my money to sign up for the MTEL (Massachusetts Tests for Educator Licensure) exams. Does anybody have any words of advice for me? Any high school physics teachers want to confirm or deny that it's enjoyable? Should I run as far as possible from this path?
