Dr. Meers, This method has been applied by several of their instructors including myself. The difficulty is because these student have had directors in the past cater to their every whim. They feel as if they have every right to challenge you the instructor or classmate if necessary. It really gets frustrating when instruction is being given and the ones you are educating are trying to educate you and the majority of the time their information is incorrect or outdated. Stern talk or assertiveness with them in particular, opens another can of worms because it is like grade school where they tattle and you are left looking like the problem isn't with them but you. Thank you, Sandra
