Hi Ken, You are absolutely correct! Address the issue immediately. If you as the authoritative figure purposely ignore issues, the matter will only get worse. Once students know where the stand in your class, you generally will not have any problems because they know you will not tolerate such behavior. I have had students that will show out in other instructors' classes, but they are an angel in my class because they know I will not tolerate certain behavior. I nip things in the bud immediately. I am a stickler for the school's rules, policies and procedures, and my students know this. Patricia
