YouTube has given life to some unique genres and types of videos. One of these -- the video essay -- can be a great tool for media-literacy education. Here's why: Video essays ground their arguments in important cultural or political topics. For instance, some video essays might expose the way media represent gender or race. Others may look at how media evolve over time and interact with the world at large. Almost all of them present compelling questions or topics, then dig into them using media as evidence and explication. Most importantly, video essays model for students how YouTube can be a platform for critical communication.
