<p>I was horrified when I read this post because I realized that I did not know how I would react. I have received questions from my students for which I did not have an answer and the way I handled it was telling them that it was a great question and I would do some research to find the answer and get back to them, so far that has worked. I have not had any "aggressive" students (not sure if that's the best word) but definitely found the response posted very helpful. I do feel it is a good idea to let that student know that attitude and respect are important while at the same time provind your knowledge to them and the rest of the class to maintain your leadership position.</p>
