Hi Thomas:
Yes, we can be good (or poor) role models as demonstrated by our actions each day. By being consistent, by the end of the course, the students will have a framework from which to build on for future classes or work settings.
Organized reflects planning, and students will notice when that has not occurred. Preparation reflects time and effort, and students will notice right away when the teacher has prepared well for their class - and appreciate it.
Regards, Barry
