Well, differences in culture help shed light on differences in perspective.I'm not American.
The teacher is a kind of boss, where I am. Any kind of teacher.
I would take a course if I had the time, and felt that the course would provide a learning opportunity. I would do this regardless of my personal opinion about the teacher, if I felt that the coursework materials and dialogue with other students would be valuable.Like I said, I would not even go to such a course if I would not believe the teacher to have authority. I see no point in taking a course with someone whom I don't consider an expert and an authority in the course matter.
Money?That's a waste of time and money!
