Let Students Summarize the Previous Lesson. Students often think of class sessions as isolated events—each containing a discrete chunk of content. Those who take notes during class will put the date along the top and then usually leave a space between each session, which visually reinforces their belief that the concepts and material aren’t connected. But in most of our courses, today’s content links to material from the previous session as well as to what’s coming up next. Having a quick recap is a good idea. That’s what Professor Annie Blazer does. Each of her class sessions begins with a three- to-five-minute summary of the main ideas discussed in the previous session, and that summary is presented by a student.
