In elementary school, the use of repetitive songs to help children remember concepts is commonplace and is usually very effective. Unfortunately for many students, this strategy is generally not used in later grades. A group of mathematics teachers at Westerville South High School in Westerville, Ohio, have taken this approach to a new creative level. These teachers have created a group of math rap videos on YouTube™, set to current rap music hits. The raps teach concepts such as graphing linear equations, solving systems of equations, rules of exponents, solving quadratic equations, trigonometry, and factoring quadratic equations. They are extremely catchy and have a chorus that repeats. The repetitive nature of the lyrics, in addition to the fact that students can listen to the raps over and over again while working on homework or needing some help, then becomes a way to help remember basic concepts that can be built upon as understanding grows. Research acknowledges that repetition is truly a valuable teaching strategy. But there were some key components that would ensure that this repetition would result in not just a short-term memory but also a long-term memory that could be retrieved; new information could then be "hooked" to it. These include: (1) Focus; (2) Creativity; and (3) Practice. The key seems to be that the information that is being repeated is as focused and simple as possible so that students are not overloaded with unnecessary information.
