One of the main responsibilities of school librarians is to teach students to evaluate the credibility of information. There is little evidence to suggest that students are being explicitly taught how to evaluate news obtained through social media. As avenues for giving and getting information evolve, so must ways of teaching students so that they will be prepared for college, career, and life. In addition to teaching systematic approaches to information evaluation, heuristics can be an efficient means to teach middle and high school students how to evaluate news obtained through social media in real time. A recent study (Spencer Johnson and Ann Ewbank, 2018) has established three underlying concepts that school librarians and teachers should address before teaching students how to use heuristics to evaluate news obtained through social media in real time: content, motivation, and credibility cues. By incorporating heuristics into the school library and classroom, students are being set up for success when they encounter news obtained through social media.
