“Summary sheets.   Every Monday, Wenderoth’s students are required to turn in a single sheet of certain dimensions on which they have illustrated the prior week’s material in drawings annotated with key ideas, arrows, and graphs. She’s teaching physiology, which is about how things work, so the summaries take on the form of large cartoons dense with callouts, blowups, directional arrows, and the like. The sheets help her students synthesize a week’s information, thinking through how systems are connected: “This is causing this, which causes this, which feeds back on those. We use a lot of arrows in physiology. The students can work with each other, I don’t care. The sheet they bring in just has to be their own.”
