One problem I've noticed is that no matter how good of an example I set (arriving early, being prepared, being honest and fair, etc.), many of my students do not adopt these traits. Of course, that's no reason to stop doing them, but I wonder to what extent it's my responsibility to or if it's even possible for me to teach non-idustry-specific characteristics such as politeness (not talking on phone during class or leaving repeatedly, etc.) and professionalism (punctuality, meeting deadlines, conflict resolution, etc.). My grading structure and course requirements reinforce these things, but many students just don't care.
