Sheila, you have provided some great comments here. I really agree with the comment on emotional responses. Once an instructor allows emotion to be their guide, there is almost no return and can result in no redemption. Never take a classroom issue personal. That being said, this is not to say that instructors are to be insensitive or uncaring. Instructors have to have think skin but be willing to show their care for their students on a thin slate. Students need to know you care but should never be given the power to overtake your authority.
Regards,
James Jackson
