I agree that all huge classes are not terrible.
But I think the “Classes That Are Huge Because The Prof is a Star” cohort is quite small, and the “Classes That Are Huge Because They Are Intro Classes For Popular Majors” cohort is vastly larger.
I remember my 500 person “Introduction to Social Psychology” class, with multiple choice tests and no discussion, and cannot help but think my experience would have been very different in a 20 person – or even 50 person – class.
And that is the consideration, really, in deciding what college experience best suits the student.
