After two years of mostly online classes, I've noticed something strange: I remember the lecture slides better than the discussions we had in breakout rooms. But when I meet classmates in person, I realize how much context we lost behind those muted microphones. Does online learning actually prepare students for real-world collaboration, or are we just getting better at a very specific kind of solitary screen-based work? I still can't decide if the efficiency trade-off is worth the missing human friction that sparks creativity in a physical classroom.
