I really enjoyed the information about constructivist teaching and retention; I also really agree with the idea that we are always learning and should be open to new ways. Having an evaluation after each course is a good way to effect this change. I love the idea that if I don't know the answer, I can easily say, "I will get back to you", or assign a class member to look into it. When you tell the students that you are learning also, it prepares them for life long learning which is so important.
