Fake news has been, well, in the news a lot lately. It seems no claim is too absurd to be aired.
For example, NBA legend Shaquille O'Neal has just become the fourth NBA star to make public remarks that he believes the Earth is flat, not round.
"I'm just saying. I drive from Florida to California all the time, and it's flat to me," he said on a podcast he hosts.
For the world's largest crowdsourced encyclopedia, combating myths like this is nothing new. (Check its entry on contemporary flat-eartherism, titled, "Modern flat Earth societies.")
"Wikipedia has been dealing with fake news since it started 16 years ago," notes LiAnna Davis, deputy director of the Wiki Education Foundation.
To combat misinformation, Wikipedia has developed a robust corps of volunteer editors. Anyone can write new entries and scrutinize existing ones for adherence to Wikipedia's rules on sourcing and neutrality. While it's not free of errors or pranks, what results is a resource that 50 million people turn to daily on hundreds of thousands of topics in a few dozen languages.
Today, educators are among those more concerned than ever with standards of truth and evidence and with the lightning-fast spread of misinformation online. And the Wiki Education Foundation, a freestanding nonprofit, is sharing Wikipedia's methods with a growing number of college students, striking a blow for information literacy along the way.
The foundation gives professors the technical assistance they need to assign students to write a brand-new Wikipedia entry, or expand an existing entry, on any topic in virtually any discipline.
This spring, 7,500 students are expected to participate. Among the many items past students have written on are:
Since the program began six years ago, Davis says, students have collectively added more than 25 million words of content to Wikipedia.
Jennifer Malkowski, an assistant professor of film and media studies at Smith College, assigned her class on new media and participatory culture to write and contribute to Wikipedia entries this past fall.
"One of the things they really liked about it was the ability to share knowledge beyond the professor — that audience of one," she says. While all Smith students are expected to use good research methods in their classes, knowing that their entries might be rejected outright if they didn't conform to Wikipedia's standards "felt like a higher stake than the difference between a B and an A-minus," she says.
Malkowski will be leading a workshop to help her colleagues, some of whom are less technically minded, learn how to make Wikipedia assignments in their own classes as well.
Davis says many professors report a greater level of effort from their students on Wikipedia assignments. "If you're writing something millions of people are going to read, it's a reason to do a really good job, to go into a library and get a deep understanding of the topic."
Some professors, like Tamar Carroll, an assistant professor of history at the Rochester Institute of Technology, see Wikipedia as a way to make previously neglected areas of knowledge more visible. For Carroll, it's women's history. She says a former student recently emailed her to say that her Wikipedia entry on Mary Stafford Anthony, the suffragist and sister of Susan B. Anthony, was "the most meaningful assignment she had" as an undergraduate.
There's another learning opportunity too. Every Wikipedia entry has a "talk" page, where editors discuss changes, and a "view history" page that shows additions and deletions over time.
Peeking behind that curtain, says Malkowski, helps "expose how knowledge is collectively created and how different voices might come to consensus, or not, on a particular topic." Right now, she adds, "is an especially important time to be asking these epistemological questions."
According to the foundation's own survey, 87 percent of university faculty who participated in the program reported an increase in their students' media literacy. By grinding some Internet info-sausage themselves, essentially, they gained a better understanding of what goes into it.
It's an interesting turn of events for Wikipedia, which, as Davis acknowledges, has had a bad rap in academic circles as the lazy student's substitute for real research.
"When I first started going to academic conferences, people would hide and say, 'Don't let my department chair see me talking to you,' " says Davis. She added that Wikipedia should only be a starting point for a university-level research paper.
But if you want to check what shape the Earth is, it's a pretty reliable source.
