Presented by: Sara Lissa Paulson

Subject Area(s):

Grade Level(s):


Students will examine and evaluate a ubiquitous web site (a Kidipede site, a Fact Monster site, or a Wikipedia site) according to the mnemonic RADCAB acronym: for Relevancy, Appropriateness, Detail, Currency, Authority, and Bias. They will work in pairs using a handout to think aloud a systematic evaluation of a web site in order that such critical thinking about web sites used for research becomes routine.





The RADCAB concept and mnemonic is used in this lesson with the original author’s permission. See information below:
