Dealing with disagreement: The roles of topic familiarity and disagreement explanation in evaluation of conflicting expert claims and sources     

《Learning and Instruction》2020

Learners may increasingly encounter conflicting expert reports. However, little is known about how they deal with this challenge. We examined how learners' familiarity with a controversial historical topic affects their epistemic judgments of conflicting expert claims and sources, the interplay of their claim and source evaluation strategies, and their meta-epistemic understanding of the legitimacy of the disagreement (absolutist, multiplist, and evaluativist perspectives). In two studies, topic familiarity increased agreement with belief-consistent expert claims and the perceived trustworthiness of the expert who presented these claims. Topic familiarity also impacted the coordination of evaluation strategies and led to greater reliance on knowledge-based validation. However, topic familiarity did not affect meta-epistemic understanding of the legitimacy of the controversy. In the second study, reading an explanation about reasons for disagreements between historians resulted in higher evaluativism. Teaching about expert disagreement may be a productive approach for promoting appreciation of the diversity of knowledge.  相似文献   

Choosing and using multiple information sources: Some new findings and emergent issues     

Susan R. Goldman 《Learning and Instruction》2011,21(2):238-242

This commentary highlights important contributions of four empirical investigations of how people sort through the masses of information that are now available to them and find what they need to solve some problem or make some decision. These studies demonstrate the impact of differences among information sources and the role that these differences play in people's evaluations of sources and use of the information to make decisions. Future research needs to examine changes in judgments of source credibility and information relevance as people acquire more knowledge of a topic and learn more sophisticated strategies for using multiple sources. Future studies of instructional effects on searching, sourcing and integrating multiple sources will be most informative if they collect multiple measures of processing and use of information in decision making and problem solving.  相似文献
