@LoveTheBard I’m happy that your D found her school, and I am also heartened by the fact that there are such colleges out there.
I agree that most faculty love engaged students, but most faculty are not "Big Name"s in their fields, specifically because most want to be teachers as well as researchers, since that is why they became professors in the first places. However, the research productivity which results in world famous reputations is time consuming, and rarely conducive to high investment in teaching.
At Research Universities, for most tenure cases, the teaching record has to be “OK”, while publication and funding have to be “stellar”. Professors who put as much effort into undergraduate teaching as they do into research productivity, generally do not get tenure at research universities. I have known many who ended up in non-TT teaching positions because of this. On the other hand, mentoring graduate students is important, and can determine promotion to Full Professor. However, grad student mentoring is directly related to research, and to the research profile of a department, and so, this is not really a purely educational issue
You are, however, correct, and I will add the caveat, that for some of the humanities an social science, particularly “Book Fields” (in which books are produced as the result of research or creativity), in which less time is spent on grant writing and running large research groups or labs, Big Names can have the time to focus more on education. Since they are not dependent on graduate students for their productivity, they will often be found in good Liberal Arts Colleges as well. However, this does not work for STEM, most Social Sciences and Ag, as well as some of the journal fields of the humanities, and this covers a much much wider swath of academia.
Professional fields (like law, planning, architecture, etc), in which fame is brought by non-academic achievements, are a different world entirely, since most Big Names are not academics. Those who are academics or teach at colleges usually love teaching, and are therefore a non-representative sample of Big Names in those field.
Most graduates schools are really bad at teaching PhD students how to teach, In fact, many STEM programs do not even require work as a TA, so that many academics’ first experience with teaching is the first day they walk in front of a class as a newly hired assistant professor. In some cases, when a faculty member is hired with tenure from industry, their first teaching experience is 8 years post graduation, as an associate professor.
If teaching were valued, there wouldn’t be so many non-TT faculty at research universities, including the UCs, and there wouldn’t be a decline in the number of TT positions and in increase in the number of adjuncts. A university which cares about the quality of teaching doesn’t hire contingent labor to teach, and doesn’t increase the numbers and proportion of adjuncts every year. At every research university and in every professional society, research awards come with a lot of recognition, and usually a nice chunk of money. Teaching awards come with a cheap plastic plaque, and a drop in job offers. No academic has ever been nominated to be a Fellow of the professional society because of their stellar teaching.
PS. Being married into academia gives you a better view than most. However, as a second generation academic myself, who has been in academia for decades and is marries to an academic, I think that there may still be a thing or two I can tell you with which you are not familiar, especially considering how many universities and departments I have gone through.
