<p>I think it was mentioned earlier in the thread (see post #8) that most professors (other than those engaged in research as a part of their contracts) teach three courses. Two is not a typical load. The poster, jingle, is a UVA prof. </p>
<p>Should course loads increase, it seems to me that those additional responsibilities would most likely fall upon the more junior professors - those who are also working to publish in their field. Unless something has changed drastically, publication in the field is usually a requirement for tenure, regardless of whether you are in the sciences or not.</p>
