In his freshman seminar, Dr. Paul Barreira randomly chooses discussion leaders just two or three days in advance of class. Paul chooses discussion leaders randomly and emails the leader just two or three days ahead of time. Because it is random, students can be chosen multiple times and in a row. As leaders, students are in charge of setting up the discussion by laying out three major points from the readings. They usually take about 20 minutes to do this.
Paul notes that students usually get into too much detail about an article. It takes some work for students to learn how to be discussion leaders.
