With 16 clicker questions in a weekly, three hour evening lecture in introductory astronomy, students stay awake only enough to click in. With so many clicker questions interspersed throughout lecture (approximately 10 minutes per clicker question) with not enough student-student interaction, results in the above dramatization--many students with heads down, too exhausted to take notes, only rousing themselves to make the obligatory effort to click in (for participation credit).
