At typical State U lecture halls are jammed with hundreds of students to one professor and TA's are used as cheap labor to fill in the gaps. We should utilize more Ph.D.'s. instead of a student to teacher ratio of a bazillion to one.
I would argue that the universities should focus more on the educational part of their role. Because, let's face it, right now teaching isn't very important to the career of an average postdoctoral fellow or tenured researcher. It's largely seen as an inconvenience, and something that distracts them from their "real" work. This is a terrible attitude, but very pervasive.
If you went through all the horrors of academics to get that Ph.D. and to get tenure tracked wouldn't you be frustrated if TA's tried to edge you out or were used to maximize profit over of education?
Honestly, I think most PhD's would be very happy if their teaching and administrative loads were reduced so that they could do more lab work, spend more time designing experiments, and less time interacting with undergraduate students and filling in grant applications. I think they'd be more than happy to have more graduate students teaching.
I'd also argue that there's almost no development of teaching skill within the university system, and that lecturers are often left to sink or swim as graduate TAs, then postdocs, and any skill they develop by the time they are tenured is simply a result of having spent more hours in the classroom than of any structured commitment to building better teachers.
I'd also suggest that the graduate TAs may be the people most driven and interested in the education of the undergraduate students, because they haven't yet been contaminated with the attitude that teaching =/= real work, and is a distraction from more important matters.
Or, in the case of the DNP, created a phoney baloney degree just so they could call themselves Dr.?
I doubt most PhDs are that informed about DNPs, unless they're dual trained, and also working or conducting research in a clinical environment and having to work with them. I assume here we're talking about the relatively narrow field of PhDs doing biomedical research who might be interacting with undergraduate biology students or teaching in professional medical or dental programs.
If there's anything I've seen from people with PhDs it's been a sense of confusion with the way clinicians insist on being called "Dr. Blank" all the time. This seems to be much less important in an academic environment.
As a student I was extremely frustrated that I was having to pay obscene sums for a professor that was just some dude who stood down front and you had to squint really hard to try and see him.
As was I, and I think it's a fair complaint. Undergraduate students money is used to subsidise administration and research programs. The same programs that are already being funded (however inadequately) through other sources. To a certain point, getting an undergraduate degree is as much about branding yourself by association with a (hopefully) famous / prestigious institution, than it is about obtaining knowledge. And for many students "knowledge" is roughly defined as "any combination of required courses and ridiculously easy electives that will be acceptable for preparation for the MCAT, and used in calculating a cGPA". It's far from a perfect system.
