Active Learning: Concept Checks
are an important part of class. Typically two or three physical situations are compared and a simple question posed regarding their relative behavior. Students are given a minute or so to think quietly about the question, followed by another minute or so to discuss the question with a neighboring student, where an attempt is made to work out an answer in consensus. I then ask for a show of hands for each possible answer to determine if the concept is understood well enough to continue.
