Well you are on the right path if they are involved with CEE in my opinion; also I think a lot of it is in showing them the value of improving their skills. One of the values I emphasize is that as they increase their skills, the classroom becomes easier to manage and the students have more fun which in turn the instructor has more fun. Also, I believe, most people want to do a good job but they have their own balance of effort verses return. I try to show the big picture of how the process of introspection after each day improves the return on not only the student success but how the effort and success of their job/career changes to for the positive. This does not always work with the veteran instructor that knows it all and is resistant to change or moving away from their comfort zone. In my experience those instructors will take time, and to start the process of change I usually begin pushing them slightly out of their zone increasing the distance little by little. Some may never improve and someone will decided if their good traits outweigh the poor ones.
