I don't really have a favourite teacher, so I'm just going to tell something about my least favourite teachers.
Her name was some obnoxiously long and hard to spell name I don't remember, and she was my teacher in 7th grade. She taught science, but we didn't learn anything because all we did was take stupid tests to find out how we learned(which she obviously didn't use for anything) and watch her dumb videos about this model car race thing she won once and bragged about all the time. There was an instance very early in the year when she was teaching about DNA, where she didn't know what DNA stood for, and asked the class. I knew it, there had been a poster very clearly saying "DEOXYRIBONUCLEIC ACID" above a drawn image of the double helix commonly associated with DNA in my 4th grade class. I raised my hand to tell her, and when I did, she yelled at me, "No one asked you!" Mind you, I hadn't been disrespectful, I was simply answering a question. Moving on. Around a week later, the class was separated into groups. My group was talking about some new game, and everyone was being loud, so I was attempting to be relevant and talk over them. She stopped everyone talking, at which point she yelled "Now if Mica[me] would stop screaming about her stupid game, I can tell you what you're supposed to do." with an obvious glare at me. Later on, there was a student who had a question, which they blurted out rather than asking her directly with the usual hand raise and such. I was sitting behind them, and answered. She glared at me again and wrote me up for talking out of turn. We had to do current events papers for the class, in cursive, five paragraphs, with the articles attached. I had turned mine in, and it was totally perfect. I had stayed up half the night to complete it(writer's block). She showed it to the class later with a bright red F on it because I hadn't highlighted the article, which we hadn't been told to do anyway. And the final in-class incident. We had to keep folders in a specific order for her class, and, being disorganized due to ADD, she called me in during her 8th grade class to fix it(everyone else fixed theirs during class earlier, she told me to hold mine though), and made me sit in the front of the class, and asked her 8th graders if anyone could help me, using my full(first and last) name. I felt like crying every time I went in there. I left to cry in the bathroom at least five times that year. She called home that night to ask if I had ever been taught anything before, pushed at my family situation(which was awful as it is, my dad had died about two months before school), and if I had been "civilized". I left the school, with my mother leaving a nasty note to the teacher, and later won a shitton of money for my new school by winning a science fair.
So yeah. She kickstarted the bullying for that year and caused a lot of my self esteem issues and depression with her bitchyness. The school never responded to us and she still teaches there.
And most recently, my 10th grade teacher, Ms Fall. She constantly corrected students with the wrong corrections("No, sweetie, it's y-o-u-r, not -y-o-u-'-r-e, "Your acting crazy""), and for our Romeo and Juliet projects, she made us watch up to the wedding scene of the Leonardo Dicaprio version, then had us write an essay on the theme of the movie(she didn't even mention it was a play or a script/book at all, we didn't read any of it), then moved on. She told us that we were wrong if we thought it was about anything but Family, and told me that Benvolio wasn't a character when I mentioned him in my essay ಠ_ಠ
