How do I handle a student who interrupts questions posed to me, the instructor?

Thursday, January 28th, 2010

I am a teacher trainer working with a group of several trainees. I have one student who regularly comments or answers questions posed to me by other students. I feel this is inappropriate unless the topic is opened for group discussion. How should this be handled? Right now I am ignoring the fact that I can hear her speaking while I am trying to address the other student's question.
