Using song in teaching is not a new idea. Songs have been used quite extensively in a variety of arenas, most notable in language acquisition. There is some empirical evidence to support the efficacy of using song in learning a new language. Furthermore, there is some theoretical support for the use of song in teaching. While the theories do not directly advocate for song, the use of song is consistent with the frameworks. This presentation will explore the educational theories that support the use of song in teaching in general, and specifically in STEM education. The questions explored are: When is it appropriate to use song in teaching? What learning goals are better served by the use of song in teaching/learning? Additionally, the limited research showing the impact of using song in STEM related fields will be discussed.
