Google amongst the academics

This article from the Seattle Times (Google for a Grade : UW class to study popular search engine) has excited a certain amount of discussion on a library listserv to which I subscribe. From the article:

Using their interest in research and technology as a backdrop, the 50 students who finish [Professor Joseph] Janes' class in March will have to determine whether Google is in fact good or whether researchers' reliance on such a simple and one-sided search tool is degrading the quality of research.

I wonder: will he require them to document the use of non-Googled sources for their research?
