As many educators are, I am interested in exploring methods that provide real-time, formative assessment in the classroom. Being a teacher of such courses as microbiology, microbial genomics, and immunology, which are dense in jargon and abstract concepts, I need to be able to quickly get a snapshot of how well my students are grasping important ideas or concepts. My students also need this information in order to assess their own learning. To this end, I started exploring the use of personal response systems, or “clickers,” as a method for rapid classroom assessment. The overall trend of the SoTL data gathered on this topic indicates that clickers can be used for formative assessment, including in my own field of biology. Awesome!
