What is a good online resource for a student who doesn't know how to write a research paper? Content I would like to see included in such a resource: how to use library databases, what a thesis statement is, how to distinguish reliable online sources from unreliable ones, how to write a bibliography, how to cite sources in the body of the paper, etc.
The target audience would be first-year undergraduates, although to be honest something written for K-12 students (particularly middle school and high school) would probably be very useful, too.
Edited to clarify: I do not mean "research paper" in the sense of "original research", but rather "Find sources about topic X in the library or online and write about them." This is a fairly common type of assignment for undergraduates (and, for that matter, high school students) in the United States in, for example, the social sciences and the humanities.
