I think teachers often forget Aristotle's idea that "the roots of education are bitter, but the fruit is sweet" because they are already educated, so they know how to do the tasks they assign, and find it hard to imagine themselves stumbling around in the shadowy ignorance of Plato's allegorical cave; and while I do my best to empathize with the plight of my students, I certainly know some of my material too well to remember what it's like not to know it -- which is why teaching the podcast Serial has been so difficult and enlightening . . . I've learned that I am much better at reading than I am at listening, and that I have trouble with details, timelines, and auditory descriptions of geography . . . I made my students write an essay connecting Plato's cave metaphor to Episode 7 and 8 of Serial and one essay explained that Sarah Koenig couldn't be manipulating us (the audience) because she is also in a shadowy cave of ignorance, the maze of her investigation, and we are -- like Inception-- inside an even shadowier cave within her cave, and then I added another layer to this: though I am the teacher, I'm not great at organizing things this dense and detail-oriented, and so I am in an even darker cave within that cave; anyway, I am listening to the episodes two or three times, in order to plan and teach each one, and the students are helping me as much as I am helping them (and often summarizing and analyzing things in ways more eloquent and precise than I am capable of, which is impressive . . . and the main thing you should learn from all this, is that if you're life is on the line, you don't want me arguing your case).
