From the Chronicle of Higher Education Feb 15, 2008:
David Parry, an assistant professor of emerging media and communications at the university, writes that students need to become familiar with new and non-static forms of communication. He encourages his students to read Wikipedia’s “history” and “discussion” pages, saying they explain how articles were produced. And he says the online encyclopedia’s entry on global warming does a good job of explaining both the controversy and the science surrounding the issue.
I use Wikipedia regularly and have few complaints. In general, I think its a great resource. While I would not end my research there (or any other single resource), I don’t have a problem starting there for quick facts. And I agree with Parry, that the discussions regarding articles can be very illuminating.
