If it becomes an issue where it is one student trying to take over the class by asking too many questions, at some point, I do ask that they write their questions down. I let them know that probably the answer will be covered through the lecture and allow time at the end for additional questions. I also encourage them to use the technology they have available to them. Many times, if they ask a question that I know they can find the answer to on their own, I will ask if they have a smart phone. Then I tell them to look it up and come back to them and let them share it with the class as well as where they found the information. This helps shift from instructor centered to student centered learning and collaborative environment.
