Students Identify Disinformation Using Stanford’s COR Method: Coronavirus, Fact Checking & Lateral Reading


Recently our high school media specialist, Ann Kaste, taught all Minnetonka High School ninth grade students Stanford's Civics Online Reasoning method for fact checking information. This is a newer, research proven strategy for discerning fake news. The core principle behind the method is to teach students to think like professional fact checkers.  Stanford discovered that readers practicing COR techniques were much more likely to quickly know what is false or misleading online. Rather than doing ‘close reading’ on a single webpage to examine elements such as the title, quality of the site, layout, name of the website URL, etc., readers practicing COR quickly begin opening up other browser tabs to fact check information and background of the content from several sources.  This method is called ‘Lateral Reading’. Readers using COR were much more likely than academic scholars to quickly and accurately determine the legitimacy of the information on a website. 

Ann began the lesson with a pre survey on a Google Form asking students to identify why it is important to be able to discern factual information online. One student explained why it was important to identify real from false information in this way: 

“It will help us build a more informed population that can make decisions for themselves without influence from others telling them what to think. It also makes the truth more clear so we don’t need to question whether something is true or false.”

Once students understood and expressed the importance of learning these skills, Ann explained and demonstrated the COR method. She showed the students some screenshots of real coronavirus Tweets. She modeled how to use the COR method to fact check the information on websites cited in the Tweets. She pointed out that some of this news is actually “bent” from the truth, not outright fake. Ann asked students the 3 COR questions: “Who’s behind the information? What’s the evidence? What do other sources say?”

Although many students may state that they already know how to ask these questions, Ann explained, “We know how to throw a baseball but we need to practice to get better at it.” The students then worked in partners to pick one of over 20 example coronavirus related Tweets and use the COR method to determine fact from fiction. Students quickly began investigating the Tweets using the COR method and then shared their findings with the group.

Having the ability to quickly identify fact from fiction online is a necessary media literacy skill in today’s world. Starting in elementary school and on into high school, our media specialists work to teach students research skills so they will be prepared for the future. This is part of an ever changing and adapting media curriculum that evolves in tandem with core classroom curricula.

Video & Voice Editing About to Make Fake News Even Harder to Decipher (& Change History, too)

The topic of Fake News is certainly in The News these days. It's also a hot topic for educators as we reflect upon how and where we teach students about recognizing whether or not something is The TruthRecently Radio Lab, one of my favorite podcasts, dealt with the topic in an episode entitled Breaking News. I found the information they shared both fascinating and frightening, and believe it's important for all educators to be aware of these latest developments and future capabilities that will further alter our future and make it possible to edit history, too:
Recent advances in technology have made it possible to edit both voice and actual video recordings more easily than ever. This includes the ability to say anything at all and have either the audio or the video (or both) be incredibly convincing. 

First, audio editing:
Adobe has a new product called Voco which enables you to drag and drop audio recordings, type in new text and nearly instantaneously press play to hear very real sounding results that are difficult to decipher as fake. With just 20 minutes of audio recording of a speaker's voice, such as a politician, celebrity or even you, the computer can pretty much create any imaginable recording from your script. More about concerns with this new tool.  

Even more startling, video editing:
As you can see for yourself in these videos, researchers are working on technology that allows them to map the facial expressions and movements of anyone from video footage and replace that with actual new edited footage created from a simple WebCam recording of another person. Basically this means anyone can be like a puppeteer. So you could take the video footage of a politician or celebrity and replace it with video of whatever you acted out in your recording. The preliminary samples demonstrating this technology online or certainly not seamless or indecipherable from something that would be authentic, but you can quickly realize the ramifications of this technology.

As I wrote about last week, things are advancing faster than we can keep up with it so it's highly likely that within the next year or so this will be in use. As stated in the Radiolab podcast, not only will this technology soon to be made available, it will likely be available as an app on all of our phones, making it possible for anyone to use. Later in the episode they discussed the difficulty experts will have deciphering whether or not these files are real or fake, explaining how it can take days now to figure the authenticity of a single photograph thought to be altered with Photoshop. Audio and video will be even more difficult.

This certainly has far-reaching implications for our future. In education, we need to be aware of these latest technological advances and inform students of it. I'm not sure exactly how we will teach students to know whether a current video or audio recording is authentic, or even whether a historical clip from decades ago is legit, altered, or completely fake. It will be necessary to teach them to research the source of something as well as the reputation of that news service, website provider, host, and/or company. A few weeks ago I wrote about the need to teach ethics within computer science. Teaching ethics and strong moral values are definitely needed with advances like these voice and video editing tools in our near future!
