As someone who finished a Baccalaureate online, I’d say these students simply aren’t prepared for the mind shift to having to learn independently. Most of my professors seemed to loathe having to teach an online class and merely threw together a mountain of almost random assignments and research papers as if to say, “if you can survive this, you can have a degree”. Most of my courses didn’t even offer video lectures and were taught by low-paid adjuncts that never responded to email. You were left alone to figure it out. It’s a whole other ball game when you don’t have the deep support system of being on campus. I hope this brings improvements to online education in general.
As part of my engineering degree, it wasn't all books and lectures. We had to learn the machine-shop, operate the lathe construct a robot, mix chemicals in organic chemistry lab, experiment with lasers in different mediums, wire hard drives... etc...
A lot of that is hands on work. No Zoom session is going to make up for that.
