An interesting assignment, but the teacher made a major error by requiring this: "Choose two topics that are appropriate", requiring a NEW article. That might have worked 2 years ago when for example the article, [[Colorado]] was a new article. But now the experience is much more about making existing articles better.
I can understand why the teacher would make this a rule, though. It's much easier to grade.
I think a better assignment would be. Pick a Wikipedia article at least 10 editors have edited within the last month and make an edit which substantially improves the article.
I think in the future a better assignment might be to pick an article from the list of requested articles. Or maybe even just pick a red link.
Of course, I would question the ethics of a professor forcing his students to release their assignments under the GFDL in the first place. Is this even allowed under school policy?
