Previous research on exploratory behaviour has predominantly focused on visual and perceptual forms of exploration, overlooking the academic aspect, where the aim is to bridge knowledge gaps. To test the effect of task and individual factors on knowledge exploration, an experimental study was conducted on 100 high school students in two sessions. In the first session, participants answered 15 multiple-choice questions without receiving immediate feedback but were given the opportunity to explore the answers. In the second session, immediate feedback was provided after each response. The results indicated that knowledge exploration was more likely to occur when students answered the questions wrongly, and the feedback on the accuracy of answers significantly enhanced knowledge exploration for incorrect answers. Session 2 also investigated the impact of factors such as Feeling of Confidence (FOC), confidence error, and intrinsic and extrinsic academic motivation on knowledge exploration. A multilevel ordinal logit model was employed to analyse the within-person and between-person relationships among these variables. The findings revealed that FOC, confidence error, and intrinsic motivation positively predicted knowledge exploration, whereas extrinsic motivation had a negative effect. These findings have significant implications for educational practice and policy. Educators can structure their course materials to cultivate students’ metacognitive awareness, thereby promoting deep engagement and enhancing their learning experience.</p>","PeriodicalId":47385,"journal":{"name":"Metacognition and Learning","volume":"29 1","pages":""},"PeriodicalIF":3.3,"publicationDate":"2024-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142189292","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"教育学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While SRSD’s beneficial effect on writing quality has been confirmed in a large body of literature, the questions of why, how, and for whom SRSD works remain unclear. To investigate the underlying cognitive and metacognitive mechanisms, and identify the factors that potentially moderate SRSD’s effectiveness, we compared fourth- and fifth-graders who either received regular writing instruction or underwent an SRSD intervention in a quasi-experimental setting. Students’ abilities to plan, write quality texts, and self-evaluate were measured. Factors that have been demonstrated to be related to writing abilities were assessed to study whether they might facilitate or hinder acquisition of strategies taught in the SRSD intervention. The results indicated that compared with students who received regular writing instruction, students who underwent the SRSD intervention produced higher-quality texts and evaluated their texts’ quality more accurately, despite persistent overestimation. Mediation analyses indicated that progress in producing high-quality texts was explained by improvements in students’ planning skills, enabling them to write stories that were better-structured and contained more ideas. However, the results also indicated that some students under the SRSD condition struggled to implement the planning strategies they were taught, particularly students with poor working memory. Recommendations for optimizing the SRSD intervention’s effectiveness in developing all students’ writing skills are discussed.</p>","PeriodicalId":47385,"journal":{"name":"Metacognition and Learning","volume":"10 1","pages":""},"PeriodicalIF":3.3,"publicationDate":"2024-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142189285","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"教育学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These indicators were measured for two tasks (text comprehension and Kanji memory) at two measurement points one year apart. Participants were 151 second graders (<i>M</i> age 7.61 years) and 176 fourth graders (<i>M</i> age 9.62 years).

Children showed heterogeneity in the proficiency of metacognition but also in the extent to which metacognitive skills were generalizable across the two tasks. For second-grade children, being low at metacognition at the first measurement point was not associated with extra risks for low metacognition one year later. However, for fourth graders, children with low metacognitive skills appeared likely to stay low in metacognition over time and particularly showed ineffective restudy decisions.

One of the skills necessary to achieve this goal is the cultivation of metacognitive vigilance—a potential means to regulate some ways of thinking held by individuals. Of particular importance is essentialism, as it underlies discourses such as racism and also hinders the comprehension of various biological models. In this paper, we aim to characterize the metacognitive regulations on essentialism made by high school students from Buenos Aires, Argentina. This exploration occurred within the context of a didactic sequence on the relationship between biology and human races, designed to promote metacognitive vigilance. Employing a qualitative approach, various types of metacognitive reflections were identified. These reflections reveal that some of the students consciously identified instances of essentialism in their daily lives, assessed its legitimacy, and constructed alternative explanations by drawing from biological models. These findings underscore the importance of nurturing metacognition as a means to deconstruct hegemonic and common-sense discourses, including those rooted in racism.</p>","PeriodicalId":47385,"journal":{"name":"Metacognition and Learning","volume":"59 1","pages":""},"PeriodicalIF":3.3,"publicationDate":"2024-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141947604","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"教育学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In a recent review article, Schwartz (2024). <i>Inferential theories of retrospective confidence</i>. Metacognition &amp; Learning.) competently summarized some of the key empirical findings on this issue and clearly articulated two different extant theoretical approaches to understanding this relationship. The <i>direct access</i> view states that one’s confidence in a memory is tied directly to the strength of the encoded memory trace, predicting a strong and near ubiquitous positive relationship between confidence and accuracy. In contrast, the <i>inferential view</i> holds that confidence is inferred from the heuristic use of available cues, and that any positive relationship between confidence and accuracy stems from the use of cues that correlate positively with accuracy. Here, I propose an alternative view that blends aspects of both accounts. Termed the <i>indirect access</i> account, I argue that memory signals and their experiential correlates form the basis of confidence judgments. This approach anticipates reported dissociations between confidence and accuracy, and accommodates a broad range of empirical findings. By this view, rare instances of weak confidence-accuracy relationships stem from strong misleading memory signals that experientially mimic strong accurate memory signals. Because strong memory signals are largely accurate, this view predicts a pervasive and robust positive relationship between confidence and accuracy.</p>","PeriodicalId":47385,"journal":{"name":"Metacognition and Learning","volume":"68 1","pages":""},"PeriodicalIF":3.3,"publicationDate":"2024-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141775591","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"教育学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nevertheless, the relationships among metacognition, mathematical modeling competencies, and mathematics achievement may be dynamic, and variables might reciprocally influence each other. Hence, we conducted a longitudinal study examining the reciprocal associations between metacognition, mathematical modeling competencies, and mathematics achievement. To this end, we recruited 408 seventh-grade students to complete a metacognition-related questionnaire and a mathematical modeling competencies test concurrently. This procedure was repeated one year later. A cross-lagged panel analysis showed four main findings: (a) metacognition in Grade 7 longitudinally predicted mathematical modeling competencies in Grade 8; (b) mathematical modeling competencies in Grade 7 longitudinally predicted metacognition and mathematics achievement; (c) higher levels of mathematics achievement drive the subsequent shaping of metacognition and mathematical modeling competencies; (d) There were no gender differences among metacognition, mathematical modeling competencies, and mathematics achievement.

Promoting SRL supports students’ SRL development and might affect students’ motivation to apply strategies. However, the link between teachers’ motivation to promote SRL and students’ motivation to apply strategies has yet to be empirically investigated. In a multilevel analysis that included 167 lower secondary teachers and their 2,785 students, we analysed the direct and indirect relationships between teachers’ self-efficacy and attainment value, the teacher- and student-reported SRL promotion and students’ self-efficacy, utility value, attainment value and cost at the class and individual level. Additionally, we investigated the contribution of teacher- and student-reported SRL promotion to find indirect relations. Teachers’ self-efficacy was related to teacher-reported SRL promotion, and student-reported SRL promotion was associated with all motivational outcomes at the class and student level except for cost. Further, we found indirect effects between teachers’ self-efficacy for SRL promotion and students’ values and self-efficacy for SRL via teachers- and students-perceived SRL promotion. No direct effects between teacher and student motivation could be found, and no significant indirect relationships were found for the cost aspect. Regarding how the signal is transmitted, the results show that including student reports of SRL promotion is especially crucial to finding indirect links. However, future studies should employ longitudinal designs and incorporate more nuanced teacher and student motivation measures in SRL to better understand the motivational links between teachers and students.</p>","PeriodicalId":47385,"journal":{"name":"Metacognition and Learning","volume":"39 1","pages":""},"PeriodicalIF":3.3,"publicationDate":"2024-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141737898","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"教育学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

On the other hand, the reliability of directed attention was 0.68, falling short of meeting the minimum requirement of 0.70. In addition, as a high degree of heterogeneity was found in the studies included, a mixed effect meta-regression was performed, identifying four moderators affecting the reliability of MALQ measures: publication year, educational setting, participants’ L1, and L2 proficiency level.
