media literacy 媒体素养, 媒介素养
Media literacy is the ability to identify different types of media and understand the messages they're sending. Kids take in a huge amount of information from a wide array of sources, far beyond the traditional media (TV, radio, newspapers, and magazines) of most parents' youth. There are text messages, memes, viral videos, social media, video games, advertising, and more. But all media shares one thing: Someone created it. And it was created for a reason. Understanding that reason is the basis of media literacy.
We Should Teach Media Literacy in Elementary School. Helping children distinguish fake from real news will give them a lifelong benefit. The digital age has made it easy for anyone to create media. We don't always know who created something, why they made it, and whether it's credible. This makes media literacy tricky to learn and teach. Nonetheless, media literacy is an essential skill in the digital age.
