I personally think that questioning is a very important, yet difficult strategy to use when teaching any subject. I feel that using the questioning strategy in the science class helps the students gain interest because they are intrigued by the content. I have found throughout my student teaching experience that students often ask questions that are guiding us away from the content being taught. I feel that it would be important for us to re-direct the class into the main point of the discussion so that we do not go into unnecessary detail. I feel that questioning becomes natural when conducting a science experiment because the students want to know what's going to happen, therefore it forces them to ask questions that are on topic. When students ask questions related to the content being taught, they build off one another and create an environment of interactive learning. I feel that it is a positive thing that your students are asking questions, they're just not asking relevant questions. I would try finding a way to re-direct them back to the content and discussion points that you want to reach.
