In today's learning environment, adult learners conduct learning episodes on the Internet meaning they are now expected to approach a self-directed science-based learning endeavor with knowledge of digital tools (digital literacy), knowledge of the science content (science literacy), and critical thinking skills to evaluate online resources (information literacy). Are adults equipped with such skills to discern credible science-based resources? If so, how are these adults discerning credibility, especially when they encounter conflicting science-based information. A recent qualitative study was conducted to delve into these questions. Participants engaged in real-time science-based Internet searches and provided feedback on rationales behind their credibility decisions. Findings from this study provided three strategies to assist those serving adult audiences in ways in which science-based resources might be best dissimilated online, especially when focused on controversial science issues such as fracking and climate change. The three strategies are (a) internally evaluate online resources, (b) conduct a usability study of online resources, and (c) stay dynamic with types of science-based resources and how to best meet the changing needs of the adult populace.
