How to teach students to evaluate Wikipedia

Inside Higher Eduation has an article on Does Wikipedia Suck? and how you can help your students separate good information from bad.

Sample paragraph:
"The most valuable lesson of all took place in the debriefing discussion the day papers were handed in. Students shared their concerns about Wikipedia’s virtues and deficiencies with each other and saw that it was a peer consensus, not a professor’s rant. I then asked them how they could evaluate all sources — electronic and print — in the same fashion as they judged Wikipedia. Within a week I had to but ask of any source “Is it sufficient?” in order to trigger thinking about evidence, logic, and data."

We need to provide students with opportunities to interact with the information and make their own decisions. We can't tell them that Google or Wikipedia is bad, we have to show them, or better, have them discover it for themselves.
