it probably varies. My daughter who got her NP essentially on line, had quite a lot of interaction with her fellow students. They can talk to each other online, and they do. Possibly the professor doesn’t know about that because they don’t see it happen or perhaps don’t bother to find out. But there is at least some interaction with the professor because students can ask questions on line.
I would say the “socratic method” would not work too well online, because students aren’t necessarily in attendance at the same time. But a lot of courses don’t adapt well to that method anyway. I don’t think it would add a lot to a course in pharmacology, for example. There’s simply a definite body of knowledge to learn and a short time in which to learn it. There’s not a whole lot of “aha” to it. You either know how this medication interacts with that one, and why, or you don’t.
English literature or drama? Yes, I can see the merits of face to face, because the understanding has to be “teased out” of things when the author did not actually intend them to be obvious, and meant to challenge the intuitive.
Public speaking? Oh yes. If you can’t see an audience reaction, you don’t know how to adjust your style and manner of presentation. But then, most don’t really master it anyway.
Endocrinology, though? Your pituitary gland is either functioning properly or it isn’t. And there are objective signs and symptoms of dysfunction. The real "aha’ moments are in practicum or internship or in practice when you’re working with real patients.
Oh yes, Trump.

Ummm. Maybe he will discover (realize) that the higher education system’s (name removed by moderator)ut is greater than its output, in short, that it’s bankrupt. He would know bankruptcy when he sees it, whether in the private or public sectors.
