Learning to integrate divergent information sources: the interplay of epistemic cognition and epistemic metacognition

Learning to integrate multiple information sources is vital for advancing learners’ digital literacy. Previous studies have found that learners’ epistemic metacognitive knowledge about the nature of knowledge and knowing is related to their strategic integration performance. The purpose of this study was to understand how these relations come into play as students learn to integrate divergent information sources. To do so, we examined the contribution of scaffolds addressing the epistemic strategy of integration and epistemic metastrategic knowledge about this strategy. Participants were 99 high-achieving Arab Israeli ninth graders. All participants engaged in writing arguments based on divergent information sources. Students in the control condition received no scaffolds; students in the strategic condition received a strategic scaffold; and students in the metastrategic condition received both strategic and metastrategic scaffolds. Integration performance, epistemic metastrategic knowledge about integration, and absolutist, multiplist, and evaluativist epistemic perspectives were measured before, immediately after, and one month after the intervention. At pre-test, both epistemic metastrategic knowledge about integration and evaluativism were positive predictors of integration performance. The strategic scaffold led to a significant increase in integration performance and epistemic metastrategic knowledge. Adding the metastrategic scaffold led to greater improvement in epistemic metastrategic knowledge, but did not result in additional gains in strategic performance. An immediate decrease in absolutism occurred among all participants but was not sustained over time. A decrease in multiplism occurred only in the experimental groups and was sustained over time. The results suggest that epistemic growth can occur in both bottom-up and top-down directions.     

Why do experts disagree? The role of conflict topics and epistemic perspectives in conflict explanations

The present study examined the role of conflict topics and individual differences in epistemic perspectives (absolutism, multiplism, and evaluativism) in students' explanations of expert conflicts. University students (N = 184) completed an epistemic thinking assessment and a conflict explanation assessment regarding two controversies in biology and history. Additionally, thirty students were interviewed and provided detailed conflict explanations that were used to interpret and extend the quantitative results. In the biology problem, conflicts were predominantly attributed to topic complexity and to research methods. In the history problem, conflicts were also predominantly attributed to topic complexity, but also to researchers' personal backgrounds and motivations. Epistemic perspectives were related to specific conflict explanations, suggesting that these perspectives have a role beyond topic differences. Thus, both conflict topics and epistemic perspectives shape lay explanations of experts' conflicts. The findings highlight differences in students’ interpretations of the roles experts play in knowledge construction.     

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

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.     

Beliefs about knowledge and knowing and multiple‐text comprehension among upper secondary students

Using a sample of 282 Norwegian upper secondary students, we examined whether two dimensions of topic‐specific epistemic beliefs, concerning the certainty of knowledge and the justification for knowing, predicted students' understanding of seven texts representing partly conflicting views on climate change. Text comprehension was measured at three different levels. Topic knowledge and topic interest were included in the analyses as control variables. Hierarchical regression analyses showed that students' beliefs about justification for knowledge positively predicted text comprehension at all three levels. That is, students believing that knowledge claims about climate change should be based on rules of inquiry and the evaluation and integration of multiple information sources did better on the three comprehension measures.     

Argumentation-based learning with digital concept mapping and college students’ epistemic beliefs

We designed an educational activity for undergraduate students and assessed how this newly-constructed activity promoted students’ argumentation skills, thereby fostering their epistemic beliefs. This argumentation-based learning activity involved digital concept mapping. A quasi-experimental design involved pretests and posttests that were administered to 52 research participants in a group and 61 participants in a control group. Students’ argumentation skills were qualitatively examined by analyzing the structure of their arguments before and after the activity. Their perceptions of the activity and epistemic belief types (from absolutism to evaluativism) were measured with the Epistemic Beliefs Scale and the Concept Mapping for Problem-Based Learning Scale. The designed activity evoked epistemic change toward evaluativism among the students who were enrolled in the activity, whereas nonsignificant results emerged for the control group. However, for both pretest and posttest, the highest score was for Absolutist, followed by Multiplist, and Evaluativist had the lowest mean. The technology-enabled concept-mapping tool supported the research group’s online argumentation design. This tool helped students mainly at the cognitive level to discern between the arguments and better learn the topic. These findings are interpreted in relation to student characteristics.

     

Epistemic Beliefs and Their Relation to Multiple-Text Comprehension: A Norwegian Program of Research

Nowadays, students are required to use multiple information sources to complete tasks, both in and out of school. The beliefs that students hold about knowledge and knowing – their epistemic beliefs – have been linked to successful integration of information across multiple texts. Framed by literature on epistemic belief research from an educational psychology perspective, this article reviews a recent Norwegian program of research on students' epistemic beliefs. The research has implications for educational research and practice that are discussed.     

The Role of Epistemic Beliefs in the Comprehension of Multiple Expository Texts: Toward an Integrated Model

In present-day knowledge societies, competent reading involves the integration of information from multiple sources into a coherent, meaningful representation of a topic, issue, or situation. This article reviews research and theory concerning the comprehension of multiple textual resources, focusing especially on linkages recently established between dimensions of epistemic beliefs and multiple-text comprehension. Moreover, a proposed model incorporates epistemic beliefs into a theoretical framework for explaining multiple-text comprehension, specifying how and why different epistemic belief dimensions may be linked to the comprehension and integration of multiple texts. Also discussed is the need for further research concerning mediational mechanisms, causality, and generalizability.     

Effects of textual enhancement on English as a foreign language learners' anaphor resolution performance and reading comprehension in Taiwan

Successful anaphor comprehension in reading is related to the explicitness of the antecedent–anaphor relation. It mirrors one of the purposes of textual enhancement (TE), which is that it raises learners' awareness of linguistic forms by enhancing the salience of input. Therefore, learners notice the enhanced form and discover the rule or relationship after they have become relatively explicit. This study investigates the effects of TE on second language learners' anaphor resolution performance and reading comprehension, to reveal the interaction among learners' comprehension, anaphor performance and noticing. Sixty EFL learners in Taiwan were divided into the control and TE groups. Participants' posttest responses were compared with respect to their anaphor resolution performance and their reading comprehension degree. The results showed that the TE group had better anaphor resolution performance, and participants' form processing did not impede their reading comprehension. These findings are discussed with both theoretical and pedagogical implications.     

Reading multiple texts about climate change: The relationship between memory for sources and text comprehension

In many situations, readers are asked to learn from multiple documents. Many studies have found that evaluating the trustworthiness and usefulness of document sources is an important skill in such learning situations. There has been, however, no direct evidence that attending to source information helps readers learn from and interpret a document's content. In this study we examined whether students' awareness of sources predicts their comprehension of documents, controlling for prior knowledge, interest and perceived comprehensibility of the texts. Participants read multiple texts that provided different perspectives on the causes and solutions of climate change. Deep comprehension was measured using both within-text and across-text inference verification tests. Source awareness was measured using a test of memory for sources. We found that memory for sources predicted both types of deep comprehension. These results, in combination with source training studies, suggest that improving students' sourcing skills may benefit their learning of text content.     

The impact of scaffolding and nonscaffolding strategies on the EFL learners' listening comprehension development

Drawing on sociocultural theory, and a large number of empirical studies conducted on the effectiveness of scaffolding on second or foreign language learning, the authors investigated the application of different forms of scaffolding to improve listening comprehension of the Iranian intermediate English as a foreign language (EFL) learners. To this end, 90 intermediate EFL learners were randomly assigned to 2 experimental groups and a control group. During 15 treatment sessions of listening comprehension instruction, expert peers in the first experimental group assisted their less knowledgeable peers in their listening comprehension tasks. The participants in the second experimental group were asked to assist their coequal peers while doing the listening comprehension tasks, but the participants in group 3 did not interact with each other or even their teacher and no scaffolding scheme was used when they were doing the listening comprehension tasks. One-way analysis of variance and post hoc analyses revealed that the expert peers' scaffolding was the most effective procedure for the intermediate EFL learners' listening comprehension development. Furthermore, coequal peers' scaffolding was proved to be the second effective procedure for the listening comprehension improvement. The findings underscore the relative efficacy of different forms of scaffolding procedure and the superiority of the expert peers' scaffolding over coequals' scaffolding. The qualitative analysis of the recorded data indicated that the implicit scaffolding strategies were more frequently used by the expert peers. However, the explicit scaffolding strategies were more frequently used to by the coequals. The findings of the study underscore the positive potentiality of scaffolding in its different forms for the EFL learners' listening comprehension development.     

Developing and testing a model of direct and indirect relationships between individual differences,processing, and multiple-text comprehension

The purpose of this study was to test a hypothesized model that specified direct and indirect linkages between the individual difference variables of epistemic beliefs, need for cognition, individual interest, and prior knowledge, the processing variables of effort, deeper-level strategies, and situational interest, and multiple-text comprehension. Using a path analysis approach with a sample of 279 Norwegian upper secondary school students, results indicated that students' effort and deeper-level strategies predicted their multiple-text comprehension, with the individual difference variables indirectly affecting multiple-text comprehension through their influence on effortful, adaptive multiple-text processing. In addition, students' prior knowledge about the topic of the texts seemed to affect their multiple-text comprehension directly as well as indirectly. Both theoretical and educational implications of the results are discussed.

The benefits of metacognitive reading strategy awareness instruction for young learners of English as a second language

This paper presents a small‐scale study examining the effects of metacognitive reading strategy instruction on English language learners' reading comprehension in a Hong Kong international school. Twenty‐five primary school (Grade 5) students who learn English as a second language participated in this study. Metacognitive instruction was incorporated into 10 process‐based reading lessons. Data were collected from notes learners took during reading, post‐reading reflection reports, teacher‐facilitated group discussions and two types of reading tests. Results revealed that the young learners could articulate several knowledge factors that influenced their reading. In addition, learners reported a better understanding of the nature and demands of reading, a deeper awareness of metacognitive knowledge in improving reading comprehension and increased confidence in handling reading exercises. The learners also showed enhanced reading performance compared to those in a control group without metacognitive intervention. This study highlights the potential of metacognitive instruction to enhance primary school English learners' reading literacy.     

Effects of response prompts and diagram comprehension ability on text and diagram learning in a college biology course

Embedded response prompts are an effective method to support multimedia learning. Response prompts are directives situated within instructional material. Responding to these prompts affects learners' cognitive operations. Different types of prompts affect learning differently due to variations in stimulated cognitive operations. This study compared three types of experimental response prompts; prompts to self-explain the contents of a page, prompts to attend to diagrams and text-diagram relations, and prompts to self-explanation text-diagram relations; and two control conditions. Three tasks that measure verbal text knowledge, diagram knowledge, or knowledge of text-diagram relations assessed learning. The effects of diagram comprehension ability were also considered. A 5 X 3 mixed model ANCOVA revealed an interaction between prompting conditions and posttest tasks. Diagram comprehension ability was associated with task performance but did not interact with conditions.     

Training Interventions to Foster Skill and Will of Argumentative Thinking

Argumentative thinking requires not only the skill to apply argumentative strategies such as supporting theories with evidence but also the will to apply these strategies by considering argumentative thinking to be both reasonable and worthwhile. Focusing on direct instruction for the initial acquisition of both skill and will, we developed a new short-term computer-based training intervention. We tested its effects on learning processes and learning outcomes in an experimental study with 147 German high school students. Our intervention fostered facets of both skill (i.e. a declarative knowledge about argumentation) and will (i.e., epistemic orientation, intellectual values, and epistemic knowledge). We gained additional insights into learning mechanisms, such as the mediating effects of the learners' self-explanation activities and the advantage of addressing will before skill.     

Justification beliefs and multiple-documents comprehension

Building on the multidimensional framework of epistemic cognition proposed by Greene et al. (Educational Psychologist 43:142–160, 2008), this study examined beliefs about justification of knowledge claims in science among 65 Norwegian 10th graders. The first research question asked whether beliefs in personal justification, justification by authority, and justification by multiple sources differed in strength among the participants. It was found that the students most strongly believed in justification by authority, followed by justification by multiple sources and personal justification. The second research question asked whether the three types of justification beliefs differentially and uniquely predicted the comprehension of multiple conflicting documents on a science issue. In a multiple regression analysis with multiple-documents comprehension indicated by essay performance as the dependent variable, both personal justification and justification by multiple sources emerged as unique predictors when topic knowledge was controlled for. Specifically, beliefs in personal opinion as a means of justifying knowledge claims in science was negatively related to multiple-documents comprehension, whereas beliefs in justification through corroboration across multiple sources of information were positively related to multiple-documents comprehension. This study provides new evidence about relationships between epistemic beliefs and new literacy competencies needed in an information society, such as integrating across multiple conflicting sources of information; relationships that may also have practical implications.     

Effects of different text display types on reading comprehension,sustained attention and cognitive load in mobile reading contexts

Despite the popularity of mobile reading devices, many studies have indicated that small screens restrict information transmission, adversely affecting reading performance on mobile devices. Moreover, mobile reading typically occurs in different reading contexts. Therefore, suitable text display type for mobile reading in different reading contexts should be considered, such that learners can effectively read content. This work selected the frequently used static and dynamic text display types (i.e. Paging and Auto-scrolling) and assessed their effects on mobile reading performance. Furthermore, the features of static and dynamic text display types were considered when designing a mixed text display type for mobile reading. Based on brainwave detector, reading-comprehension test sheet, and cognitive-load scale, this work designed a mobile reading experiment with a two-factor experimental design to assess the effects of the selected static, dynamic, and designed text display types, which were respectively presented in sitting, standing, and walking contexts, on reading comprehension, sustained attention, and cognitive load of learners. Experimental results show that sitting obtained the highest sustained attention and the mixed text garnered lowest sustained attention. Moreover, although analytical results show that no significant difference existed in overall reading comprehension with each text type presented with the mobile reading contexts, reading comprehension (i.e. memory, comprehension, and application types) was significantly affected by the reading context, and to some degree, the text display type. This work also found that the text display type is a major factor affecting learners' cognitive load; however, learners' cognitive load is not be affected by the considered reading contexts. Among the three text display types, the mixed type generates the highest cognitive load, followed by the dynamic type, and then the static type. In conclusion, the three reading contexts with the three text display types have both advantages and disadvantages for reading comprehension, sustained attention, and cognitive load. As a result, text display type for mobile reading on small screens should be adjusted according to reading context or to improve reading comprehension, attention, or cognitive load.     

Does mind wandering mediate the effects of habitual reading motivation on comprehension?

The present article reports on a study that examined how individual differences in habitual reading motivation affect a reader's tendency to engage in text-related and text-unrelated thinking during reading. Two-hundred participants read each three texts about finance and meteorology topics and answered comprehension questions afterward. Participants' thoughts during reading were assessed with retrospective ratings and thought samples. Habitual reading motivation was assessed with questionnaires in a separate session prior to reading. Structural equation models fit to this data revealed that more motivated readers reported less mind wandering, more engagement in elaborative thinking and comprehension monitoring, as well as higher topic interest. Furthermore, the beneficial effect of reading motivation on comprehension was partially mediated by mind wandering, elaboration, comprehension monitoring, and interest. Our findings offer a novel explanation for the well-known beneficial effects of reading motivation on comprehension: habitually motivated readers are more likely to engage in text-related thinking and avoid text-unrelated thoughts.     

Effects of Processing Time on Comprehension and Calibration in Print and Digital Mediums

This study explored the effects of processing texts in print or digitally on readers' comprehension, processing time, and calibration. Eighty-six undergraduates read print and digital versions of book excerpts about childhood ailments presented in counterbalanced order. Comprehension was tested at three levels (i.e., main idea, key points, and other relevant information). Direct comparisons between print and digital reading demonstrated a significant advantage for reading in print on students' recall of key points and other relevant information but not the main idea. When processing time was added as a mediator variable, it significantly affected the relation between medium and comprehension for all question levels. In terms of calibration, students read more quickly and judged their performance higher when engaged digitally, although their actual performance was much better when reading in print. Implications of these findings for subsequent research are considered.
