P.R.O.V.E.N. is designed to provide students with a source evaluation process that is grounded in both the ACRL Framework and Michael Caulfield's "Four Moves and a Habit" from his ebook, "Web Literacy for Student Fact-Checkers" (2017). The process includes both strategies for fact-checking by examining other sources such as internet fact-checking tools, and strategies for analyzing the source itself by examining its purpose, relevance, objectivity, verifiability, expertise, and newness.
