Replying to Education Today

So today, my math teacher who's been in my school district gave us a spiel on how she's been determined as an "ineffective" teacher when a year ago she was "an effective" teacher. This has to do with a lot of complaints from parents and students about her teaching. Now I think that's total bs. Call me old fashioned, but I think students should have to adjust to the teachers style, not the other way around. I know all students learn a different, and they have to work in conjunction, but it makes me mad that a teacher who's been here for 17 years is on her way out because she refuses to change. And yes, she is very old fashioned in her teaching methods. She doesn't accept any bad behavior and wants the best out of her students. It just makes me mad that she's being treated this way.
