Spec ran a story yesterday about a new program at the Graduate School of Arts and Sciences that will allow students to teach small, 15-student-max seminars to undergraduates. This has apparently already been going on during the summer, but could be offered during the school year starting next semester.
Some graduate students are very in favor of this, as it will give them experience teaching and will ultimately make them more expert-y in their areas of expertise. Others, surprisingly, would rather rely on experienced professors to create a curriculum for them.
As an undergraduate in SEAS who is unlikely to ever take or teach any of these courses, I still think it’s a pretty cool plan. Because the courses wouldn't be required, students would be free to take what I imagine would be a pretty cool seminar class on a subject that really interests them. It's a way to gain more exposure to new subjects, or go deeper into them than we would in normal undergraduate classes.
