Zach, well stated and you are 100% correct, students will push boundaries until they fully understand what they can and cannot get away with. A good guide will have command of the classroom. Students will be obedient out of respect for the instructor and their fellow classmates. There will be at times a student or two that simply does not fear the consequences and in those rare cases you may need to solicit the help of your administrators and other members of the faculty. In over 20 years of teaching I have only had to remove two students from their programs so it can happen but should be a very rare event. James Jackson
