For several years, I've taught students about how to decide if something is reliable online, a skill that I think is beyond essential in the world of higher-education and the general job market. It has taken many times of teaching this to refine what actually makes something trustworthy or not, and much examination of how I make these decisions myself. (Try it. Next time you Google something, analyze how you decide what to click on, and once you get there, how you decide if it's something you should trust.) I finally decided to compile all this information into a Google Doc and would love anyone else to add in their own input!
Please note: I don't use websites like the tree octopus to teach students about reliability. The vast majority of websites are NOT trying to trick people. However, they are trying to persuade them, from various perspectives, and it's critical for students to know how to identify those perspectives.
