Hi Michelle, First I have a private talk with the student and tell him/her how much I appreciate their insight and questions but in all fairness I have to include all of the other students in the discussions and Q&A sessions. I then suggest they limit their questions to a certain number say 3 per class session. This generally works because I have reinforced their knowledge (be it true or not) and so they back off with the questions. If this doesn't work I ask him/her to write down their questions in advance so I can respond to them throughout the class. If they forget and start to ask questions I only have to give them a glance and point to the question cards. I have also told such students that they have three or five questions to ask they must use them wisely because I will not call on them once they have reached their limit. So here are three ways to help you out with this situation. If you have any more questions or if I can be of help let me know and I will be glad to respond. Thanks. Gary
