I agree.  Sometimes it is easy to stay in a teaching style that is comfortable for you instead of having the flexibility to change styles that are best suited to the current group of students.

I also recommend randomly changing the groups you create so that they do not become overly competitive.  I have found this leads more to students helping each other rather than "trying to win at all costs"

I find it helpful to have contact with others who have different teaching styles to keep us open to new teaching options.
