Today's teens have grown up online. They make friends online. They do homework online. And surely they get their news online. But because they are so comfortable with the Internet, they seldom question the news stories online and pass along to their friends.

Now William Colglazier, a history teacher at a high school in America, is teaching his students how to think critically(批判性地) about online information and recognize(识别) a fake(假的) news story.

His idea came from a study on people's online reasoning(推理) at Stanford University. The study found that young people lack(缺少) ability to reason about the information on the Internet Most middle school students in the study could not tell the difference between an advertisement and a news story, and high school and college students fully trusted the websites ending in ".org".

The good news is that，according to Colglazier, once teens realize they've been cheated, they have strong will to tell truth from lies. "But they need some advice on how to find evidence(证据) and how to recognize when others use poor argumentation(论据)," he said. Some of the advice that Colglazier offers his students include moving off the site to find more information about the site, the writer's motivations(动机) and the organization behind the news story.

Colglazier shared some of his course with other teens in Teen Vogue, a famous magazine. He hopes more kids would take away some knowledge about thinking critically when they read news online. "The Internet is both beautiful and ugly," he said. "If people cannot tell real news from fake news, the results can be frightening."
