I think the first thing to remember is that a lot of news stations and organizations are motivated by profit in order to keep their operations going. This means that many have an incentive to exaggerate and editorialize things in a way that generates maximum attention.
These companies have found that the most effective way to get clicks and views is to mess with human emotions. To make us angry, to make us feel pride, to make us disgusted. It doesn't want us to think, it wants us to react. So starting from that point of view, we have to make sure we are able to think critically and separate fact from opinion. To understand that the words or actions of one person do not speak for millions of other people.
To be as unbiased as we can, it's important to get our information from a variety of sources. To see what facts line up, what facts were left out from one source, and what facts get included in another.
It's a little bit like having a balanced diet. We don't just want to eat all carbs or all dairy or all protein. To have a healthy perspective, we have to have a healthy balance of information.
If I were in your shoes, I would encourage my students to learn how to find answers on their own. To remain skeptical and objective until they get to hear different perspectives. To have a well-balanced information diet
