I chuckle when I run into teachers and coaches who put on affectations when in front of a group of students, athletes, or their parents. I pray that I am not one of those instructors. Nothing would kill my motivation more than someone who puts on airs. Relevant stories, especially those that seem to expose the secrets or realities of the profession, tend to catch the students' ears and increase motivation. Though class time is short, when a student asks a question that begins "What about this?" it's clear that the student is thinking and applying, or at least exploring.
