Investigating professed and enacted epistemic beliefs about the uncertainty of scientific knowledge when students evaluate scientific controversies

Prior research on epistemic beliefs, that is, individuals’ views about knowledge and knowing, has mainly focused either on individuals’ professed beliefs (as reported in questionnaires) or on their enacted beliefs (as indicated during task processing). However, little is known about the relation between professed and enacted epistemic beliefs. The present study focused on beliefs about the uncertainty of scientific knowledge and investigated both professed and enacted beliefs in the context of evaluations of scientific controversies. Participants were N = 79 university students who first completed a questionnaire that targeted their professed uncertainty beliefs about scientific knowledge. Then, approximately 1 week later, they completed a standardized test in which they evaluated five scientific controversies. Cued retrospective verbal reports were used to measure their enacted uncertainty beliefs while taking the test. Results revealed that professed and enacted uncertainty beliefs were interrelated and that both variables predicted individuals’ performance with regard to the evaluation of scientific controversies. Furthermore, the effect of professed uncertainty beliefs on controversy-evaluation performance was partly mediated by enacted uncertainty beliefs. The findings of the present study point toward novel theoretical insights and educational implications regarding the relations between professed and enacted beliefs about the uncertainty of scientific knowledge and their role in individuals’ evaluation of scientific controversies.

     

Associations of epistemic beliefs in science and scientific reasoning in university students from Taiwan and India

The purpose of this study was to compare the associations of epistemic beliefs in science, performance of scientific reasoning in university students from Taiwan and India, and the relations with their science learning experiences. A total of 126 university students including 67 from Taiwan and 59 from India who had science and mathematics backgrounds were involved in the study. Students’ epistemic beliefs in science were assessed by the SEV questionnaire, while their reasoning performance and learning experiences were prompted by open-ended questions and survey items. Content analysis was performed to analyze their scientific reasoning, and correlation analysis, t tests and ANOVA were applied to reveal the associations between variables. The results showed that students from both countries differed in epistemic beliefs in the dimensions of certainty, development and justification. While few students from either country performed successfully in identifying genuine evidence and giving full rebuttals, Taiwanese participants seemed to demonstrate slightly better scientific reasoning. It was found that the Indian students were more balanced in receiving structured and engaged learning experiences. Varying associations for the students from the different countries were found between epistemic beliefs and scientific reasoning performance, and between epistemic beliefs and science learning experiences.     

Promoting scientific understanding through electronic discourse

This paper illustrates the on-going efforts of an innovative science program called “Kids as Global Scientists” to take full advantage of Internet technology for better learning and teaching. We analyzed electronic communication between students and scientists on the Message Board and the development of students’ scientific understanding through electronic communications. Our research shows that the Internet has great potential to foster the development of students’ scientific understanding, which is difficult to achieve through traditional instruction alone. Despite increasing interest in the use of the Internet in the classroom, research on the educational benefits of the Internet on learning and teaching are still limited. This study will serve in this continuing research base in order to help expand our understanding by opening a discussion around the following questions: What are the characteristics of new learning opportunities and interaction patterns that students experienced? What new classroom dynamics and challenges are introduced as a result of the use of our technological innovations?

Developing instruments concerning scientific epistemic beliefs and goal orientations in learning science: a validation study

ABSTRACT

The purpose of this study was to develop and validate two survey instruments to evaluate high school students' scientific epistemic beliefs and goal orientations in learning science. The initial relationships between the sampled students' scientific epistemic beliefs and goal orientations in learning science were also investigated. A final valid sample of 600 volunteer Taiwanese high school students participated in this survey by responding to the Scientific Epistemic Beliefs Instrument (SEBI) and the Goal Orientations in Learning Science Instrument (GOLSI). Through both exploratory and confirmatory factor analyses, the SEBI and GOLSI were proven to be valid and reliable for assessing the participants' scientific epistemic beliefs and goal orientations in learning science. The path analysis results indicated that, by and large, the students with more sophisticated epistemic beliefs in various dimensions such as Development of Knowledge, Justification for Knowing, and Purpose of Knowing tended to adopt both Mastery-approach and Mastery-avoidance goals. Some interesting results were also found. For example, the students tended to set a learning goal to outperform others or merely demonstrate competence (Performance-approach) if they had more informed epistemic beliefs in the dimensions of Multiplicity of Knowledge, Uncertainty of Knowledge, and Purpose of Knowing.     

Epistemological beliefs and epistemic strategies in self-regulated learning

How do epistemological attitudes and beliefs influence learning from text? We conceptualize epistemological attitudes and beliefs as components of metacognitive knowledge. As such, they serve an important function in regulating the use of epistemic strategies such as knowledge-based validation of information and checking arguments for internal consistency. We report results from two studies that investigated the effects epistemological attitudes and beliefs on the use of epistemic strategies in academic learning and the motivational states that mediate these effects. Study 1 (N = 289) tested a mediation model with epistemological attitudes (separate vs. connected knowing) and textual characteristics as distal predictors, and learning goals (learning factual knowledge vs. developing an own standpoint) as mediator variables. Separate knowing had large indirect effects on the use of epistemic strategies via the goal to develop an own point of view. In addition, learners adapted their learning goals and epistemic strategies depending on objective characteristics and the perceived familiarity of the texts they read. In Study 2 (N = 124), epistemological beliefs concerning the uncertainty of knowledge increased the use of epistemic strategies only when extrinsic study motivation was low. A mediated moderation model established this effect to be mediated by specific epistemic curiosity. These results illuminate the mechanisms of how epistemological attitudes and beliefs affect self-regulated learning. In contrast to other types of learning strategies, the use of epistemic strategies seems to be strongly and consistently linked to epistemological attitudes and beliefs.

Understanding children's epistemic beliefs in elementary education

Research shows that the beliefs individuals hold about knowledge and knowing (epistemic beliefs) influence learning approaches and outcomes. However, little is known about the nature of children's epistemic beliefs and how best to measure these. In this pilot study, 11 Australian children (in Grade 4 or Grade 6) were asked to ‘draw, write and tell’ about their epistemic beliefs using drawings, written responses and interviews, respectively. Drawings were analysed, with the majority of children depicting external, one-way sources of knowledge. The written statements and interviews were analysed using inductive thematic analysis, showing that children predominantly described knowledge acquisition as processes of task-based learning. Interviews also enabled children to describe a wider range of views. These results indicate that the methodological combination of ‘draw, write and tell’ allowed for a deeper understanding of the children's epistemic beliefs which holds implications for future research.     

Deaf children's understanding of beliefs and desires

Twenty-two children (5-12 year old) who were profoundly, prelingually deaf were given two tests designed to tap their 'theory of mind', that is, their ability to attribute independent mental states to other people. The tests were versions of Baron-Cohen, Leslie, and Frith's Sally-Anne task and of Baron-Cohen's breakfast task. Seventy percent of the children were successful on all questions requiring belief attribution, a considerably and significantly larger percentage than the 29% obtained by Peterson and Siegal for a similar sample, though it is still lower than would be expected on the basis on chronological age. Children were universally successful on questions requiring the attribution of desire. We discuss implications of the findings.     

Internet-specific epistemic beliefs and self-regulated learning in online academic information searching

Epistemic beliefs have been considered as important components of the self-regulatory model; however, their relationships with self-regulated learning processes in the Internet context need further research. The main purpose of this study was to examine the relationships between Internet-specific epistemic belief dimensions and self-regulated learning activities while using the Internet for academic information searching. A total of 758 university students were sampled in this study. Through factor analyses, four dimensions of Internet-specific epistemic beliefs were identified, labeled as certainty of Internet-based knowledge, simplicity of Internet-based knowledge, source of Internet-based knowledge, and justification for Internet-based knowing. Factor analyses also revealed two dimensions of self-regulated learning while using the Internet for academic searching, namely preparatory self-regulated learning (i.e., task definition as well as goal setting and planning) and enactment self-regulated learning (i.e., controlling, monitoring, and reflecting). The results of the structural relationship analysis indicated that the preparatory phase of self-regulated learning positively correlated with Internet-specific epistemic beliefs relating to justification for Internet-based knowing, and was also negatively associated with two other dimensions of Internet-specific epistemic beliefs regarding simplicity of Internet-based knowledge and source of Internet-based knowledge. In addition, preparatory self-regulated learning mediated the relationships between these three dimensions of Internet-specific epistemic beliefs and the enactment phase of self-regulated learning.     

Effects of text structure,reading goals and epistemic beliefs on conceptual change

We investigated the online and offline effects of learner and instructional characteristics on conceptual change of a robust misconception in science. Fifty‐nine undergraduate university students with misconceptions about evolution were identified as espousing evaluativist or non‐evaluativist epistemic beliefs in science. Participants were randomly assigned to receive a traditional or refutational text that discussed a misconception in evolution and a general comprehension or elaborative interrogation reading goal. Participants' cognitive and metacognitive processes while reading were measured using a think‐aloud protocol. Postreading, participants' correct and incorrect conceptual knowledge were separately assessed with a transference essay. Results showed that text structure and reading goals affected cognitive conflict, coherence‐building and elaborative processing while reading and promoted correct conceptual knowledge included in essays but failed to affect the inclusion of misconceptions. Further, participants with evaluativist epistemic beliefs engaged in fewer comprehension monitoring processes and were more likely to adapt their coherence‐building processes according to reading goals than their non‐evaluativist counterparts, but epistemic belief groups did not differ in the content of the posttest essay. Theoretical and educational implications of these findings are discussed.     

The curious case of climate change: Testing a theoretical model of epistemic beliefs,epistemic emotions,and complex learning

We propose a theoretical model linking students' epistemic beliefs, epistemic emotions, learning strategies, and learning outcomes. The model was tested across two studies with 439 post-secondary students from Canada, the United States, and Germany for Study 1, and 56 students from Canada for Study 2. For Study 1, students self-reported their epistemic beliefs about climate change, read four conflicting documents about the causes and consequences of climate change, self-reported their epistemic emotions and learning strategies used to learn the content, and were given an inference verification test to measure learning. Study 2 used the same procedure but added a think aloud protocol to capture self-regulatory processes and emotions as they occurred. Path analyses revealed that epistemic beliefs served as important antecedents to the epistemic emotions students experienced during learning. Students who believed that the justification of knowledge about climate change requires critical evaluation of multiple sources experienced higher levels of enjoyment and curiosity, and lower levels of boredom when confronted with conflicting information. A belief in the complexity of this knowledge was related to lower levels of confusion, anxiety, and boredom. A belief in the uncertainty of this knowledge predicted lower levels of anxiety and frustration, and a belief in the active construction of knowledge predicted lower levels of confusion. Epistemic emotions predicted the types of learning strategies students used to learn the content and mediated relations between epistemic beliefs and learning strategies. Learning strategies predicted learning outcomes and mediated relations between epistemic emotions and learning outcomes. Implications for research on epistemic beliefs, epistemic emotions, and students' self-regulated learning are discussed.     

Student profiles of knowledge and epistemic beliefs: Changes and relations to multiple-text comprehension

Using cluster-analysis in a sample of 65 Norwegian 10th graders, we identified subgroups characterized by relatively high levels of knowledge combined with relatively low beliefs in personal justification of knowledge claims, as well as subgroups characterized by the opposite pattern of knowledge and personal justification. Moreover, the high knowledge/low personal justification groups differed with respect to the strengths of their beliefs in justification by authority and justification by multiple sources. After having read multiple conflicting texts on a science topic, the majority of students increased their knowledge about the topic and lowered their beliefs in personal justification, combining this pattern with higher beliefs in either justification by authority or justification by multiple sources. The subgroup characterized by relatively high level of knowledge and relatively low level of personal justification in combination with strong beliefs in justification by multiple sources performed best on a multiple-text comprehension measure. Theoretical and educational implications of the study are discussed.     

Exploring the relations between epistemic beliefs,emotions, and learning from texts

Conflicting claims about important socio-scientific debates are proliferating in contemporary society. It is therefore important to understand the individual characteristics that predict learning from conflicting claims. We explored individuals’ beliefs about the nature of knowledge and knowing (i.e., epistemic beliefs) and their emotions as potentially interrelated sets of learner characteristics that predict learning in such contexts. Undergraduate university students (N = 282) self-reported their topic-specific epistemic beliefs and were given three conflicting texts about climate change to read. Immediately after each of the three texts, participants self-reported the emotions they experienced. Following reading and self-report, participants wrote summaries of the conflicting texts. Text-mining and human coding were applied to summaries to construct two indices of learning from conflicting texts that reflected which source’s information is privileged in memory. Results from structural equation modeling revealed that epistemic beliefs were consistent in their predictions of emotions, which in turn variously predicted different learning outcomes. In particular, a belief that knowledge is justified by inquiry predicted surprise and curiosity, which at times facilitated learning. In contrast, confusion, predicted by passive reliance on external sources, related to impaired memory of conflicting content. Theoretical and methodological implications are discussed for research on the relations between epistemic beliefs, emotions, and learning about controversial topics.     

Implicit theories,epistemic beliefs,and science motivation: A person-centered approach

The purpose of this study was to explore (a) the individual belief profiles that naturally arise among middle and high school science students (n = 1225); (b) the relationships between these profiles to science achievement and other prominent motivation variables; and (c) the demographic and developmental differences among the belief profiles. Results revealed that a four-class solution fit the data the best. These profiles were differentially related to achievement goal orientations, science self‐efficacy, and science achievement. Differences in profiles also arose as a function of minority status, grade level, and gender. Findings support and refine Schommer-Aikins's (2004) Embedded Systemic Model of epistemic beliefs. Results are discussed in relation to theory and implications for science instruction.     

The role of learners’ epistemic beliefs in an online Community of Inquiry

The Community of Inquiry (CoI) model provides a lens to examine online learning through three elements: teaching presence (the design and facilitation of learning experiences), social presence (the extent to which learners project themselves as real people) and cognitive presence (the extent to which learners are able to construct meaning through inquiry and reflection activities). While research to date has established the importance of these essential presences in online learning environments, recent research on the CoI model calls for the need to explore the role of learner characteristics. The current study responded to the call by examining the role of learners’ epistemic beliefs (EB) (ie, individuals’ fundamental beliefs about the nature of knowledge and knowing) in an online CoI. Multiple linear regressions analyses revealed that EB moderated the relationship between learners’ perceived teaching presence and cognitive presences. Future studies on CoI should take learners’ epistemic beliefs into consideration, especially in the case of low teaching presences. Theoretical and practical implications for designing and investigating online learning are discussed.
