One thing about online classes is there might be someone with some knowledge of education helping to develop courses.
Hmm. Only if their role is to help present it, not if their role is to determine content. We've seen what happens when "educators" take over the content side and sneer at mathematicians, engineers, and other subject experts who object to spiral math/whole language reading/math with no right answers, etc. You can't teach something if you don't know how to do it really well. You also have understand the theory behind what you're teaching and what comes much later.
If college is a filtering device to identify the intelligent and self-motivated, ...
There is much more discussion in the media and online forums on how to get into Harvard et al. than on whether students learn more at Harvard, suggesting that the filtering role of college is primary.
But for many people, Harvard and other IVY LEAGUE SCHOOLS are not about learning or intelligence or self-motivation. They are about status and making connections so that you get a high-paying/high-status job. And a lot of this stuff is driven by Mom and Dad, who feed it to their kids.
I went to a prestigious school and am not saying this out of a sense of sour grapes. I'm quite annoyed about the situation and the crassness that underlies it.
