Behind students' increasing pull toward extracurriculars

Harvard Magazine
If you went to college in the late 90s,
with internet, you may be like “nah, not much has changed.”

But I’m ancient enough to remember a time when going to a SLAC could mean four years in a tiny town with almost no media consumption. Wars happened and I didn’t notice. I knew nothing about career paths, wasn’t paying attention to contemporary tech. My whole model of self-improvement was to read Wittgenstein & study Greek. It’s kind of lovely, but it required immense naïveté.
I wonder whether her account also holds for Harvard STEM students. What she describes seems specific to classes centered on reading and writing, not relatively merciless problem sets and exams.
I teach a bit across both types of courses, and i think you’re probably right.
