Like yourself I ask my students questions because this allows him or her to particapte in classromm discussion and sometimes assists on drawing the quiet students out of their shell. I have found there are those who are always eager to answer questions, and sometimes do not want to give another student a chance to answer, so what I have found that works is to call a student by name so each student can have a chance and if or when I feel they may not know the answer, I will tell them I will come back to them later and move on to another student. This also helps with studetns paying attention in class
