I find that each student has their own challenges. One difficultly that I have been having is while training the student that "acts up" for the sake of arguement, the other students are not aware that you are addressing the problem. Certainly, it is not my place to discuss any disaplinary, or specialized training, with the rest of the class. I'd be interested to know how others handle this situation. Although they do see the difference over time, it doesn't stop the rumor mill, or the scuttlebutt. How do you recommend letting the other students know that the behavior is being addressed without sharing confidential information regardin the student that is affecting the overall class perception? I am open to all recommendations and thank you. jay
