That research and undergraduate education are combined together is the real problem here.
The problem isn’t pairing the two but generations of overhead growth combined with a decline in the federal funding which used to support researchers, both of which mean compensation has fallen behind in real value.
And this skill has very little overlap with teaching undergraduate students.
And on the other end, a fairly small percentage of students end up doing any research in college.
In an ideal world, researchers would research, and people who specialize in teaching would teach.
You do NOT have to be some cutting edge leader in your field to teach undergrads. Simple skills, like being an engaged and interesting speaking are way way way more important than how many papers you've published.
Some of my worst teachers were teaching specialists.
And the most influential person in my undergraduate career? A researcher.
My point is the research and teaching are orthogonal skills.
It is certainly possible for someone to be both a good researcher and a good teacher.
I am just saying that I don't care how good of a researcher they are. The only thing I care about is how good of a teacher they are.
So let's judge the teachers based SOLELY on their teaching skills, and not have writing papers have anything at all to do with whether they are hired as a teacher.
