We tell our students that they need to learn to work as part of a team...they need to learn to give feedback...they need to communicate with their peers about "free riding"...and that they will need these skills in whatever job or career they pursue. They do, they will...and we (meaning the faculty) don't.
Having worked in more than one Fortune 100 corporation, I can attest to the general lack of comfort with the concept of "feedback." The reasons are numerous, ranging from fear of litigation to lack of knowledge. Yet, despite the discomfort in corporate settings, the egg shells in the academic community are far more fragile. Where are the role models for our students, not in theory, but in practice?
