This paper reviews studies of peer feedback from the novel perspective of the providers of that feedback. The possible learning benefits of providing peer feedback in online learning have not been extensively studied. The goal of this study was therefore to explore the process of providing online peer feedback as a learning activity for the provider. We concluded that (1) providing online peer feedback has several potential learning benefits for the provider; (2) when providing online peer feedback, students use different cognitive processes; (3) the cognitive processes and the potential learning benefits can be realised when students use specific elements in the feedback they provide. 相似文献

Learning Networks (LNs) are online social networks designed to support nonformal learning; they are therefore particularly suitable for self-directed learners. In LNs, learners need to construct knowledge through knowledge sharing with other participants. However, without support, learners have to organize knowledge sharing themselves and this could induce extraneous cognitive load. When working on complex learning tasks, this organizing process could have a detrimental effect on knowledge construction. To optimize cognitive load, we propose using a peer support system that applies the mechanisms of peer tutoring to support knowledge sharing. Its mechanisms reduce, we argue, the extraneous load imposed by having to organize knowledge sharing as well as induce germane load by directing the freed-up cognitive capacity to processes that contribute to knowledge construction. 相似文献

Teaching domain-specific skills before peer assessment skills is superior to teaching them simultaneously 总被引：1，自引：0，他引：1
Instruction in peer assessment of complex task performance may cause high cognitive load, impairing learning. A stepwise instructional strategy aimed at reducing cognitive load was investigated by comparing it with a combined instructional strategy in an experiment with 128 secondary school students (mean age 14.0?years; 45.2% male) with the between-subjects factor instruction (stepwise, combined). In the stepwise condition, study tasks in Phase 1 were domain-specific and study tasks in Phase 2 had both domain-specific and peer assessment components. In the combined condition, these two components were present in all tasks in both phases. Final performance (i.e. speed and accuracy in domain-specific skills and peer assessment skills) showed no significant differences, but performance improved more from Phase 1 to Phase 2 in the stepwise condition than in the combined condition. The results suggest that, with complex study tasks, it might be beneficial to teach domain-specific skills before peer assessment skills. 相似文献

Electronic portfolios (eportfolios) can increase reflection, develop content and pedagogy skills and facilitate communication
between teachers and administrators. However, they have limitations. Despite resources that teacher institutions devote to
eportfolios, research suggests that most implementations are of limited duration. In a climate where sustained professional
development and lifelong learning are necessary to remain competitive, organizations should reevaluate how eportfolios are
implemented to sustain use and maintain skills deemed important by teaching organizations. Using principles of change theory,
this article identifies several eportfolio challenges and how they may be improved through principles of personal learning
environments. Implementation procedures and limitations are also provided. 相似文献

Peer review is a reciprocal process whereby students produce feedback reviews on the work of peers and receive feedback reviews from peers on their own work. Prior research has primarily examined the learning benefits that result from the receipt of feedback reviews, with few studies specifically exploring the merits of producing feedback reviews or the learning mechanisms that this activates. Using accounts of their experiences of peer review, this study illuminates students’ perceptions of the different learning benefits resulting from feedback receipt and feedback production, and, importantly, it provides insight into the cognitive processes that are activated when students construct feedback reviews. The findings show that producing feedback reviews engages students in multiple acts of evaluative judgement, both about the work of peers, and, through a reflective process, about their own work; that it involves them in both invoking and applying criteria to explain those judgements; and that it shifts control of feedback processes into students’ hands, a shift that can reduce their need for external feedback. The theoretical and practical implications of these findings are discussed. It is argued that the capacity to produce quality feedback is a fundamental graduate skill, and, as such, it should receive much greater attention in higher education curricula. 相似文献

Involving students in peer review has many pedagogical benefits, but few studies have explicitly investigated relationships between the content of peer reviews, student perceptions and assessment outcomes. We conducted a case study of peer review within a third-year undergraduate subject at a research-intensive Australian university, in which we examined: (1) students’ perceptions of the peer review process before and after peer review, (2) content of the peer reviews and what kinds of feedback were adopted and (3) the effect of participation in peer review on performance (grades) in the assessment task. Students overwhelmingly perceived peer review to be beneficial, and the opportunity to participate in peer review resulted in a significant improvement in the quality of work submitted for assessment. Students who benefited most from peer review were those of below-median performance, and the magnitude of benefit was related to the degree to which students engaged with the peer review process. Our study confirms that participation in peer review can lead to important improvements in performance and learning outcomes. 相似文献

This study examined the effects of question prompts and peer interactions in scaffolding undergraduate students’ problem-solving
processes in an ill-structured task in problem representation, developing solutions, making justifications, and monitoring
and evaluating. A quasi-experimental study, supplemented by multiple-case studies, was conducted to investigate both the outcomes
and the processes of student problem-solving performance. The quantitative outcomes revealed that question prompts had significantly
positive effects on student problem-solving performance but peer interactions did not show significant effects. The qualitative
findings, however, did indicate some positive effects of peer interactions in facilitating cognitive thinking and metacognitive
skills. The study suggests that the peer interaction process itself must be guided and monitored with various strategies,
including question prompts, in order to maximize its benefits. 相似文献

The peer relationships of young children with mild developmental (cognitive) delays recruited at 4-6 years of age were examined in a longitudinal study across a 2-year period. Results revealed only modest increases in children's peer interactions, a high degree of intraindividual stability, and the existence of a poorly organized and conflict-prone pattern of peer interactions. Child cognitive and language levels as well as family stress and support were associated with children's peer interactions. A subgroup was identified of initially low interactors who were at especially high risk for future peer interaction problems. These findings further underscore the importance of designing and implementing early intervention programs in the area of peer relationships for children with mild developmental delays. 相似文献

In this study the relationship between domain-specific skills and peer assessment skills as a function of task complexity is investigated. We hypothesised that peer assessment skills were superposed on domain-specific skills and will therefore suffer more when higher cognitive load is induced by increased task complexity. In a mixed factorial design with the between-subjects factor task complexity (simple, n?=?51; complex, n?=?59) and within-subjects factor task type (domain-specific, peer assessment), secondary school students studied four integrated study tasks, requiring them to learn a domain-specific skill (i.e. identifying the six steps of scientific research) and to learn how to assess a fictitious peer performing the same skill. Additionally, the students performed two domain-specific test tasks and two peer assessment test tasks. The interaction effect found on test performance supports our hypothesis. Implications for the teaching and learning of peer assessment skills are discussed. 相似文献

Although peer assessment is widely implemented in higher education, not all students are highly engaged in it. To enhance student engagement in peer assessment, we designed and developed a web-based tool, autonomy-supportive peer assessment (ASPA), to support students’ need for autonomy when they conducted peer assessment. Students’ sense of autonomy, and their behavioral, emotional, and cognitive engagement in peer assessment were examined via interviews and surveys. We also examined students’ academic performances, including their improvement from initial to revised essays and the quality of feedback they provided. Survey results indicated that the ASPA group (1) experienced a slightly higher sense of autonomy than the non-ASPA group, and (2) spent much more time on each evaluation criterion than the non-ASPA group. Interviews suggested that both the ASPA and non-ASPA groups were engaged in peer assessment. However, there were no statistically significant differences between the two groups in behavioral, emotional, cognitive engagement, and academic performances. 相似文献

The interactions between levels of learner prior knowledge and effectiveness of different instructional techniques and procedures
have been intensively investigated within a cognitive load framework since mid-90s. This line of research has become known
as the expertise reversal effect. Apart from their cognitive load theory-based prediction and explanation, patterns of empirical
findings on the effect fit well those in studies of Aptitude Treatment Interactions (ATI) that were originally initiated in
mid-60s. This paper reviews recent empirical findings associated with the expertise reversal effect, their interpretation
within cognitive load theory, relations to ATI studies, implications for the design of learner-tailored instructional systems,
and some recent experimental attempts of implementing these findings into realistic adaptive learning environments. 相似文献

The reported study investigated students’ perceptions of their high-performing classmates in terms of intelligence, social skills, and conscientiousness in different school subjects. The school subjects for study were examined with regard to cognitive, physical, and gender-specific issues. The results show that high academic achievements in particular school subjects lead to negative reactions in the peer group whereas high achievements in other school subjects result in positive peer reactions. In contrast, the respondents’ gender and the gender of the successful classmates had little influence on student perceptions of high achievers. The results are discussed in regard to their implications for gifted education. 相似文献

This paper reviews research literature on cognitive load measurement in learning and neuroimaging, and describes a mapping between the main elements of cognitive load theory and findings in functional neuroanatomy. It is argued that these findings may lead to the improved measurement of cognitive load using neuroimaging. The paper describes how current measures of cognitive load cannot accurately show the distinction between different types of cognitive load in different learning conditions, and existing approaches to cognitive load assessment are limited in terms of their precision and methodology. A literature review discusses the conceptual framework of Sweller's [Sweller, J. (1994). Cognitive load theory, learning difficulty, and instructional design. Learning and Instruction 4, 295-312; Sweller, J. (1999). Instructional design in technical areas. Camberwell, Australia: ACER Press] cognitive load theory, and describes various approaches to load measurement and their limitations. The paper then describes how the core components of cognitive load - intrinsic, extraneous, and germane load - may be observable using neuroimaging techniques, and argues for the exploration of new links between education research and neuroscience. 相似文献

This study examined the effects of classroom indegree for ability (the degree to which peer nominations as academically capable show high consensus and focus on a relatively few number of children in a classroom) on first grade children's peer acceptance, teacher-rated classroom engagement, and self-perceived cognitive competence. Participants were 291 children located in 84 classrooms. Participating in sociometric interviews were 937 classmates. Consistent with social comparison theory, classroom indegree moderated the associations between children's achievement and classroom engagement and peer liking. Children with lower ability, relative to their classmates, were less accepted by peers and less engaged in classrooms in which students' perceptions of classmates' abilities converged on a relatively few number of students than in classrooms in which peers' perceptions were more dispersed. High indegree was associated with lower self-perceived cognitive competence regardless of ability level. 相似文献

This article reviews contemporary research on multimedia learning that uses cognitive load theory as the major theoretical framework. In particular, we address the extent to which working memory has been conceptualized and measured in this research, what kind of subjective measures of cognitive load have been used and whether such measures are combined with other measures of cognitive load, and how results from subjective measures have been related to learning and achievement. The findings show that most of the reviewed studies did not include any clear conceptualization or measurement of working memory, used only general subjective measures containing one or very few items, and did not report findings consistent with the hypothesized relationship between cognitive load and multimedia learning. The findings are discussed in relation to the broader goal of improving research on cognitive load in the context of multimedia learning. 相似文献

Maternal Support Networks, Maternal Cognitions, and Young Children's Social and Cognitive Development 总被引：1，自引：0，他引：1
The relations among maternal support networks, maternal perceptions of parenting, maternal attributions for parenting situations, and children's social development, as indexed by peer acceptance, and cognitive performance, as indexed by the PPVT-R and PSI, were examined in a sample of 69 mothers and their preschool-age children. Network characteristics directly predicted cognitive performance and indirectly predicted peer acceptance through effects on maternal perceptions and attributions. Parent cognitions as mediators of network effects on children's development are discussed, addressing variation due to network dimensions, types of parent cognitions, and domain of children's development. 相似文献

This study examined how a range of physical punishment measures, ranging from mild corporal punishment to physical abuse, are associated with cognitive performance, school engagement, and peer isolation over a 3- year span among 658 children initially observed between the ages of 8 and 14. Physical punishment was captured in three groups: mild corporal punishment, harsh corporal punishment, and physical abuse, and both caregiver- and child-reported punishment measures were considered. After accounting for socioeconomic and demographic characteristics, only Ninitial exposure to physical abuse was significantly associated with declines in cognitive performance. However, all forms of physical punishment were associated with declines in school engagement, and harsh corporal punishment was associated with increased peer isolation. Our findings were relatively consistent regardless of whether physical punishment was reported by the child or caregiver. Overall, our findings suggest that the prevention of physical abuse may enhance children's cognitive performance, but that alone may not be sufficient to ensure children are engaged and well-adjusted in school. 相似文献
