Jerry,
Good point. I think others feel the same way. What I try to do is ask students on a formative basis (about 3 weeks into a 15 week course and again about 6 weeks) as to what they would like for me to stop doing, start doing and continue to do (Stop, Start, Continue method). They typically make suggestions and if I can change something based on their suggestion, I do. If I can't change it, I explain why and that usually is because it's tied to a learning objective. But, then the students see you want their feedback… >>>
