I won't toot my own horn too much but will paste one here.
"This instructor is passionate and knowledgeable about the subject, has a friendly teaching manner and is very approachable and flexible. He also had a sense of humour about himself, which helped to relax the class. I quite enjoyed this experience and I think I learned a lot about the basic principles/concepts of linguistics and how I could apply them to teaching. I had a couple of eye-opening realizations in this course, too, which were not just due to what I read, but to how the instructor presented it and discussed it."
