Avoiding Wikipedia

Some professors have expressed their grave concerns over the students' use of Wikipedia as their source in research papers, theses, etc. Instead, they would suggest to cite credible sources like books, journals, and trustworthy electronic sources.

What if the book one is using cited Wikipedia as its source? That's where problem comes in.

A case in point is the book we are using right now for our subject Educ M (The Teaching Profession). The book is authored by Purita P. Bilbao, Brenda B. Corpuz, Avelina T. Lagas and Gloria G. Salandanan, all of whom are Ed.D. and Ph.D. holders.

Evidence: In page 6, it said in the second paragraph:

After you have gotten an idea on the philosophy/ies you lean [sic] let us know more about each of them. The following notes were lifted from http://en.wikipedia.org/wiki/Philosophy_of_education.
