<p>Let's clear up "taught by students." Only a very few courses are taught by graduate students. If I understand correctly, it may be only Ec10. I understand that Larry Summers himself taught Ec10 as a graduate student. In the other courses that have more than 28 students, a prof may have a TF. TFs lead sections that are in addition to, not instead of, lectures by profs.</p>
<p>When considering LACs vs. midsized research universities such as Harvard, it's useful to find out the class size of courses one is thinking of taking, not focus on the exceptional cases. It would be as wrong to focus on Ec 10 as the defining experience at Harvard as it would be to focus on the freshman seminars (capped at 12). </p>
<p>Now that my S#1 has graduated from a LAC, I have a different perspective on the TF issue. Granted that the ideal would be a class with no more than 20 students, is it better to be in a class of 35-50 students (51 such classes at Harvard) with 2 or 3 TFs or a similar size class with no TF? Or worse, would it be better for the class to be capped at 35 or 50, but be shut out of it, as S#1 was ? S#1 had wanted a LAC because he wanted a more nurturing environment, yadda, yadda; we paid the same tuition for that LAC as we will for S#2 at Harvard; but I believe S#2 will not be shut out classes as S#1 was at his LAC. The only class he is likely to be shut out of is a freshman seminar of his choice, because of the cap on enrolment.</p>
<p>Another perspective. When a prof has 40+ students and no TF, s/he may give different homeworks, papers and exams than a prof who can rely on TFs to grade papers and exams. My S, who audited some courses, found the comments by the TFs very helpful. And when he could not read their handwriting, he just asked them to elaborate. Many students prefer to talk to the TFs, partly because they feel closer to the in terms of age, and do not bother going to profs' office hours.</p>
<p>Personally, I feel that the key difference in the college experience is that a LAC is smaller and makes for a more tight-knit community than a mid-sized research university and especially than Harvard. Its hundreds of EC groups, the convenient public transportation mean that students can fan in many different directions. For some, this is great. For others, it makes for a lack of school spirit. Take your pick.</p>
