I tried reading the article but could not get past the paragraph containing the sentence, “Yes, you heard correctly—some courses at one of the world’s most prestigious courses (sic) are taught by fellow undergrads.” The sentence is misleading. Some select undergraduates lead discussion sections or grade assignments, but they are not the instructors of record. It is standard procedure at research universities for graduate students and some undergraduates to lead discussion sections. (It is more common for undergraduates to lead discussion sections for technical subjects such as computer science and math.) It is good experience for the teaching assistants, and it provides the students in the course with an alternative perspective. Having said all this, I agree that the LAC route is better for some students. Like other posters, we have one Ivy grad and one LAC student, and each is happy with the choice she made.
