Teaching the law of supply using karaoke

This paper describes an active-learning strategy for teaching the law of supply using karaoke. Unlike the law of demand, which is second nature by the time students reach college, the law of supply is less familiar. If you are unsure about this claim, poll your class to see how many students have tangible experience running a business. Due to this lack of familiarity, we deploy karaoke to illustrate the fundamental nature of the supply curve, along with the difference between movements along the supply curve and supply shifters. We also provide extensions and a number of variations of this method for interested educators. This work is similar to Kraznoshon’s (2013) use of Beyonce’s Irreplaceable to help students learn the law of demand.
