I was always under the impression that Wikipedia was not a reliable source of investigation as others can edit articles to add inaccurate content. But just like a Wiki you would need to sign in to make comment and your comments would be tracked. As all websites one must be sure of the reliability of the content and safety of the site. If it sounds ridiculous it most likely is incorrect and you move on to the next article.
I would use this wiki in my classroom as one source of investigation. I don't think I would use it as my sole source of information. Just as we look at numerous texts, journal articles, websites to glean our information for our assignments it is vital to teach our students that Wikipedia is not the answer for every question. Sure, it can certainly be a starting point but not the end point. Wikipedia has its place in the classroom if used correctly and judged for what it is: One source of information that can lead to other sources.
