Lead by example in all areas. Be honest.

I have learned that there are many other methods that can be used to assess student understanding of a topic than just exams.

I have never really paid much attention to the Bloom's taxonomy, but will now. I agree that it is important to have the lessons planned out. I know I have been guilty of "winging" it and relying on my experience and knowledge to present information. While the information I present was accurate, it maybe was not presented in the most logical order to facilitate the student's learning to the maximum efficiency.
