We extend previous theoretical and empirical work by examining the role that emotions and epistemic judgments play when learning from different refutation plus persuasive and expository plus persuasive texts. We examined how variations in messages designed to change misconceptions and attitudes about genetically modified foods (GMFs) might differentially impact the extent to which individuals engage in epistemic judgments; the emotions individuals experience during learning; and, how epistemic judgments and emotions might facilitate or constrain conceptual and attitudinal change. One hundred twenty-five undergraduate university students were randomly assigned to one of four text conditions: refutation plus positive persuasive text, refutation plus negative persuasive text, expository plus positive persuasive text, or expository plus negative persuasive text. Students were asked to think and emote out loud during learning to capture epistemic judgments and emotions as they occurred in real time. After the learning session, students also self-reported the emotions they experienced during learning. Results revealed that students who were given positive persuasive texts experienced more positive emotions (both intensity and frequency) during learning, whereas those who were given negative persuasive texts experienced more negative emotions (frequency) during learning. Students who were given positive persuasive texts engaged in more epistemic judgments and changed more misconceptions about GMFs compared to students in the other three text conditions. Finally, epistemic judgments were significant positive predictors of conceptual and attitudinal change, and both positive emotions and negative emotions predicted attitudinal change. Implications for theories of conceptual and attitudinal change are discussed. 相似文献

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

Physical education (PE) lessons involve complex and dynamic interactive sequences between students, equipment and teacher. The potential for unexpected and/or unintended events is relatively large, a point reflected in an increasing amount of scholarship dealing with classroom management (CM). This scholarship further suggests that unexpected and disruptive events negatively impact on learning and can have deleterious effects on teacher health. Despite considerable potential for these kinds of events, many PE lessons occur in structured, organized ways. The broad purpose of this paper is to consider how classroom action becomes ordered in PE contexts. To this end, an interactional approach is put forward including the specific analytic concepts of directives, epistemic authority and deontic authority. To exemplify the approach, the micro-dynamics of a situation in which a group of students are building a human pyramid is examined. The examination draws attention to: how the teacher engages in a series of interactions with the students to move the sequence forward; how the students themselves achieve order through their interactions with one another; and how the characteristics of the activity help to organize the students' behaviors and limit possibilities for action. The discussion is located against a backdrop of current CM scholarship. Reference is also made to two aspects of social context: the increasing prominence of managerial discourse in educational arenas and the significance of student-centeredness in pedagogical theory. Both aspects appear to influence how order can be achieved in PE today. The analysis raises issues related to pedagogy, management and authority which are addressed in the final two sections of the paper. 相似文献

Despite mounting research on how the news media portrayed climate change in developed countries, disproportionately little attention was paid to one of the top greenhouse gas emitters in the world—China. This study systematically examined and compared how the US and Chinese newspapers portrayed climate change. An analytical framework, grounded in framing research traditions, took into account both theoretical and practical challenges in frame analysis by creating a hybrid structure of interlocked generic and issue-specific frames. The results showed both convergent and divergent pictures from the two countries’ newspapers shaped distinctly by the sociopolitical realities in both countries. The research also cautioned against making simplistic explanations of the results and offered culturally informed interpretations. A discussion on better research focus and design was offered for future research in this avenue. 相似文献
