The objective of the panel is to discuss the credibility and authority of information in learning environments, considering the changed circumstances of digital media. The panelists will use theoretical and empirical examples from their own research on how students at various educational levels construct the credibility and authority of information, both in traditional and digital learning environments. Four related research questions will be addressed by the panelists: What constitutes "credibility" for high school students? What is the relationship between students’ assessment of cognitive authority of information and their learning outcomes of inquiry-based assignments? How are college students' credibility assessment related to their information seeking goals and strategies? How can credibility and authority of information be understood in a sociocultural framework on information literacy? These questions are constantly increasing in importance along with the growth of new and more interactive digital media. Individuals’ responsibility for and capability of critical source evaluation is of significant importance for both information science researchers and professional practitioners. Together, the panel contributes to a more nuanced and deepened understanding of credibility and authority of information in learning environments through the examinations of different empirical settings. The panel therefore wishes, from an information science perspective, to stimulate a continuing discussion and future awareness of these issues. The panel concludes with rich opportunities for discussing the questions addressed with audience participants.
