I totally had students do this.
I had seen the Wikipedia list of misconceptions floating around Twitter, and figured it would be an interesting exercise for my reading classes. We had previously investigated other sites' discussion pages in an activity I call "Wikipedia Behind the Scenes," and this seemed like a logical next step.
I made a preassessment, a true/false "quiz" with 12 misconceptions I thought my students might know. ("T/F: Bats are blind.") They took the quiz, we shared the results ("show of hands... how many thought #1 was true?"), and then I sent them into the computer lab to find out which of the answers were correct. (I was a little mean; all the answers were false.)
After a few minutes, in dismay and excitement, they brought back their findings. We talked about the sources of misinformation--friends, parents, teachers--and tried to figure out how wrong things get to be "common knowledge." I showed them the list, and we looked at the "discussion" page to see the disagreements over what ought to be listed. (Consider this a vote to keep it.)
In sum: Wikipedia is a marvelous teaching tool, and any educator who disagrees is a nincompoop.
