On the way to class this morning listening to NPR I heard this story, which came on the heels of this story.
I thought it weird that no one kinda put the two together, at least directly. The NYU sociology professor at one point said that college professors work hard, but that in many cases the sole criteria for judging their effectiveness is student evaluations. As an adjunct professor, that's certainly the case for me. I had an administrator visit my class once after I got hired, and said admin person sat there for five minutes, took some notes, and walked out and I never heard anything about a "faculty eval."
So in order to get good student evals many professors don't have rigorous coursework, are entertaining, and grade easily. All = happy students = good evals = keeping job = students don't learn.
On top of that there's retention. Whenever they say not-for-profit college or university that's some serious bullshit. They need those people in seats otherwise budget cuts are gonna force layoffs. So it's in the professors' and administrators' favor to be easy in order to keep college enrollments up. All of that = happy stupid unemployable students.
