If there is a student who always asking questions then let the class know that today they only need to ask questions that deals with what they are discussing and if they have any additional questions they could meet with her when class is over.

Even in college I deal with colleagues who do the same thing, question after annoying question and most of the time her questions do not pertain to anything we are discussing in class at that time. As the teacher, if I noticed this was becoming a habit of one of my students, and other students were being distracted, annoyed, or affected negatively by her incessant questioning, I would schedule to have a small conference with the student either after class or at a time when other students were not around. During this time, I would address the problem and ask my student why they felt the need to ask so many questions. If I am able to get to the root of the reasoning for asking so many questions, I could then suggest ways for the student figure out certain things on their own without having to constantly interrupt the lessons. I could also help my student distinguish between dire, necessary questions versus questions that could wait until after class to be asked. Then, together, we could decide on an appropriate number of questions the student could ask within a given time frame. Allotting only a certain amount of questions to be asked might also help my student think before raising their hand and learn the significance of saving questions for moments when they really do not understand something.

I have encountered this problem in my classroom before as well. I do believe in promoting students to ask questions because this is an incredible way for the teacher to get a better idea of how the student understanding material and just what is going on in their lives, but I agree that it can keep other students from learning. When questioning becomes a distraction I like to make a point to tell the students that we are only asking questions about the given topic. If the students have any other questions they would like the teacher to answer that is not related to the current topic, they could write those questions down and put them in a question jar. With the jar, the teacher would answer the questions for the student later in the day or week. I would make a point to tell the students a specific time or day that the questions would be answered so they are not consistently asking when. This would allow your time to be used more efficiently and give them an outlet.

I would recommend that teacher talk with the student after class. Discuss that the questions asked are off task and disruptive. Provide examples to the student of the "off-task" questions and have him/her agree on a way to resolve the problem. If the problem persists, remind the student with a signal that his/her question if off task, and continue instruction. If this still does not work, suggests that the student write down the questions on an index card which I will review at the end of class and respond to accordingly.

I would ask the student before they ask the question, is this related to what we are doing now? If the student says yes then I would allow them to ask the question. I would also tell them they can ask me the other questions at a later time.

I would bring the class to an attention that their is no such thing as stupid questions so that they don't laugh at the person. I would ask the child if it is a serious question when she raises her hand. If nothing works, then I would tell the child one on one that this isn't appropriate.

Having the student write down their questions maybe a better solution. A lot of the time, the teacher will answer the question later on within the lesson. If they still have questions after, maybe leave a few minutes at the end of the lesson for question time

I would the students a limited number of questions to ask. He would get poker chips to indicate how many questions he can ask for the lesson. Every time he asks a question, the teacher takes a chip. It will teach the student to chose his questions carefully.
