Abstract
With developments in technology (e.g., “Web 2.0”sites
that allow users to author and create media content)
and the removal of publication barriers, the quality of
science information online now varies vastly. These
changes in the review of published science information,
along with increased facility of information distribu-
tion, have resulted in the spread of misinformation
about science. As such, the role of evaluation when
reading scientific claims has become a pressing issue
when educating students. While recent studies have
examined educational strategies for supporting evalua-
tion of sources and plausibility of claims, there is little
extant work on supporting students in critiquing the
claims for flawed scientific reasoning. This study tested
the efficacy of a structured reading support interven-
tion for evaluation and critique on cultivating a critical

We developed and validated a questionnaire to measure
epistemic vigilance, implemented a large-scale (N=1081)
Randomized Controlled Trial (RCT) of an original reading
activity that elicits evaluation and critique of scientific
claims, and measured whether the intervention increased
epistemic vigilance of misinformation. Our RCT results
suggested a moderate effect in students who complied with
the treatment intervention. Furthermore, analyses of
