During crisis contexts, information is both critical for user's decision making and simultaneously challenging to evaluate. When online information's credibility is ambiguous, young learners are challenged to evaluate rapidly evolving online information. This study sought to explore how 8th-grade students evaluated an ambiguously credible Tweet involving an extraordinary image of Hurricane Dorian. Students rated their skepticism about the image, provided a warrant for their rating, and hypothesized a purpose behind the original poster's tweet. Students demonstrated three approaches to evaluating the tweet: focusing on information content over source, assuming internet-specific authorial purposes, and applying in-school literacies. This study highlights that educators can use ambiguously credible texts to support students in evaluating online information by supporting student equivocation between contradictory content and source credibility.
