The point is to enter the discussion with something you'd like to learn from it. You are free to structure class discussion any way you see fit. Many discussion leaders prefer to begin class by reviewing the required readings for the day. This review should raise specific questions and issues for the day, and relate material to previous readings and class discussions. This is a fine strategy but your summary should not take more than five minutes.
Longer summaries take away from the discussion of the material.
Your job is not to lecture, but lead discussion about the material. This discussion will lead to clearer understanding of the complexity of the readings. The discussion leader should take a strong role, to ensure that the discussion covers the material, and that there is equity and continuity in the discussion. One of the major concerns in leading discussion is to ensure that the environment is secure enough for people to ask questions and become involved. Here are some idea for how to start and sustain discussion and involve all class members.
