So my old school didn't accept Wikipedia as a source due to the possibility of it being edited, and I doubt my college is different. How accurate do you think Wikipedia is? Ever found false information(not vandalism)?
It's not a valid source for anything more than idle curiosity, and getting a vague overview on a subject. This of course varies from topic to topic, with some being far more accurate and in depth than others, but on the whole for anything more important or deep than a bar-room discussion of "I wonder what was about?".
If I remember correctly there was a really good quote about Wikipedia that's appropriate for this question. To paraphrase, "The people who need Wikipedia don't have enough knowledge to accurately judge the information they're reading; the people who have the knowledge to accurately update Wikipedia don't have the time to".
There was actually a study carried out by my University whilst I was there over the reliability of Wikipedia (admittedly a completely different department) which was interesting in showing an "acceptable" level of accuracy in Wikipedia.
Besides the "accuracy" of Wikipedia, the main reason for centres of education not deeming "Wikipedia" as a valid reference - especially for scientific matters is that it's a tertiary source of information, more often than not being quotes of quotes of data obtained elsewhere. Alot of meaning can be lost unintentionally because of this - that and it's an important skill in academia in being able to deal with source materials (whether scientific results, mathematical equations or Shakespearian prose) without the need for someone to "paraphrase" it into a form you are more comfortable with, to keep the information "pure" and unbaised.
