Recently I stumbled upon a series of videos called "5 Levels of Difficulty". In each video an expert explains a difficult concept in 5 levels of increasing complexity:
I was inspired by this video series for a few reasons. First, it reminded me how explaining a difficult concept to a novice and expert audience simultaneously requires deep conceptual knowledge and how listening to such an explanation helps to build simultaneous conceptual and mechanical knowledge of a concept. Second, it motivated me to reimagine how I assess my students. Keeping the above in mind, for our unit on Cellular Respiration in my freshman Biology course, rather than assign a traditional topic exam, I decide to create a variation of the 5 Levels of of Difficulty videos shown above that will serve as the assessment for this topic. In short, students will create similar videos explaining Cellular Respiration at 3 rather than 5 levels of difficulty.
I have embedded a document below that explains the intricacies of the assignment. Click here to view the spreadsheet where student "3 Levels of Difficulty" scripts and videos will be collected. Comments are closed.
