> One needs only to look at how expensive small liberal arts colleges are. If their teachers spent more time in the classroom and less doing arcane research, the costs would come down.
But small liberal arts colleges are the places that already do primarily prioritize teaching, and expect professors to do relatively little research. Professors typically teach more courses per semester than at research universities, and are hired and promoted primarily based on teaching ability rather than research portfolio. This was the case at the Claremont Colleges, at least, where I went for undergrad; most professors just did a little research on the side, maybe one paper a year, and spent nearly full-time teaching. They're expensive mainly because they have very small class sizes (big emphasis on small discussion seminars), and typically much smaller endowments and fewer donations than the famous research universities do. Plus, since none of the salaries or lab facilities are paid for by research-grant money, those have to come out of tuition, too. And, since there are no grad students, professors typically do most of the teaching work themselves, rather than offloading a significant proportion to a TA, as is done at research universities: sections, tutorials, grading, office hours, etc. are all the professor's responsibility.
Big research universities, like MIT or Stanford or University of Texas or UCLA, are the ones that primarily emphasize research track record.
This has been my experience as well. I went to a small liberal arts college for undergrad. My teachers there did very little research, but all taught their small classes by themselves with no TA.
My particular field (music) tends to be much more expensive per student since private lessons must be taught one-on-one. One physics professor could teach 15 students for three hours a week, but a piano professor needs essentially needs 15 hours to teach each of those students for one hour a week. Some of this work can be done in small groups/classes, but higher music education is much more individual.
Some of my colleagues who have graduated now teach at liberal arts schools where their tenure requirement is essentially one presentation at a regional conference or one publication, with a strong record of teaching. Compare this to a large institution, where the expectation has traditionally been that you need a book deal in order to obtain tenure, whether or not you're much good as a teacher of undergraduates.
So here's a secondary question... Could the overall cost of the education be reduced if the intro classes were taught online? Or the non-humanities intro classes taught online?
