Class discussion of a topic can help solidify the ideas in the students' minds. When facilitating a discussion, it is important to ask a question that is not too broad as to be confusing, nor too narrow as to be too obvious. Students will not answer questions that are either of these extremes. Do not ask anything that can be answered with a simple yes or not. If the question is one that could relevant to the students' lives, they will be more apt to make comments. Try not to call on one student over and over again, and rephrase their comment back to them to make sure that they are being understood.
