As a fourth grade classroom teacher, I am constantly dealing with this issue. When is a question worth asking, and when is it just a distractor? Students have learned at a very early age to ask questions such as "Do we really have to do this?" "Can you tell me what to do?" "What are we going to do after this?" etc. without taking a moment to stop and think first. I am constantly saying to students after a question -- I am going to give you a few minutes to think about that and if you still want me to answer I will speak with you privately about it. , How does that question relate to the topic at hand? Or, How will that question, if answered, increase your understanding of the issues we are dealing with?
It takes a lot of effort to get students out of the habit of asking absurd or irrelevant questions just to waste time and hear themselves talk.
Some students appear to believe that ANY question is worthy of time regardless of whether it is related to the topic or not.
I agree with Chi-Tien, that students must learn to ask thoughtful questions, not just ask questions for the sake of asking. Question posing is an art that both teachers and students must become more skilled at.
