Did Media Literacy backfire?

“Too many students I met were being told that Wikipedia was untrustworthy and were, instead, being encouraged to do research. As a result, the message that many had taken home was to turn to Google and use whatever came up first. They heard that Google was trustworthy and Wikipedia was not.” (Boyd, 2017)

Don’t cite Wikipedia, write Wikipedia.

• Wikipedia does not want you to cite it. It considers itself a tertiary resource; an online encyclopedia built from articles which in turn are based on reliable, published, secondary sources.
• Wikipedia is relentlessly transparent. Everything on Wikipedia can be checked, challenged and corrected. Cite the sources Wikipedia uses, not Wikipedia itself.
