We initiated and structured a single program that supervised teachers, some with neuroscience or psychology degrees, to collaborate and explore the effects of science of learning‐translated pedagogy. This article reports on the 34 findings from teacher‐led randomized controlled trials (RCTs) and replications. Teachers designed trials, looking at areas such as attention, memory, and spaced learning. Overall, positive effects were found over short periods (1–6 weeks; r = 0.15, p < .0001 [d = 0.30], N = 2,157). However, retrieval practice (testing as a learning experience) had differential effects mediated by age, approach, and lesson content. Results suggest science of learning‐translated pedagogy needs extensive replication to establish how best to use laboratory evidence in classrooms. Multiple planned replication of teacher‐led RCTs has potential as an evaluation tool, combining high levels of mundane realism with strong internal validity and the potential to build cost effective large samples for meta‐analysis. 相似文献

The act of revising is an important aspect of academic writing. Although revision is crucial for eliminating writing errors and producing high-quality texts, research on writing expertise shows that novices rarely engage in revision activities. Providing information on writing errors by means of peer feedback has become a popular method in writing instruction. However, despite its popularity, students have difficulties in leveraging the potential of peer feedback: feedback uptake is low and students engage in little revision. Instructional support might help learners to make sense of peer feedback and to reflect on the provided information more deeply. The present study investigated the effect of sense-making support on feedback uptake as well as on revision skills, in particular problem detection and problem correction. In an experimental study, 73 university students were randomly assigned to conditions with or without sense-making support. The results indicate that feedback uptake improved concerning two out of three variables: students in the condition with sense-making support made fewer new errors and rejected more incorrect feedback comments. Students’ revision skills only improved with regard to problem detection. Overall, we were able to show that peer feedback alone might not be sufficient to make successful changes in the text and improve revision skills. Sense-making support proved to be effective to some extent and partially helped to maximize the benefits of peer feedback. 相似文献

Polyelectrolyte multilayers (PEMs) based on the combinations poly(diallyldimethylammonium chloride)∕poly(acrylic acid) (PDADMAC∕PAA) and poly(allylamine hydrochloride)∕PAA (PAH∕PAA) were adsorbed on poly(dimethylsiloxane) (PDMS) and tested for nonspecific surface attachment of hydrophobic yeast cells using a parallel plate flow chamber. A custom-made graft copolymer containing poly(ethylene glycol) (PEG) side chains (PAA-g-PEG) was additionally adsorbed on the PEMs as a terminal layer. A suitable PEM modification effectively decreased the adhesion strength of Saccharomyces cerevisiae DSM 2155 to the channel walls. However, a further decrease in initial cell attachment and adhesion strength was observed after adsorption of PAA-g-PEG copolymer onto PEMs from aqueous solution. The results demonstrate that a facile layer-by-layer surface functionalization from aqueous solutions can be successfully applied to reduce cell adhesion strength of S. cerevisiae by at least two orders of magnitude compared to bare PDMS. Therefore, this method is potentially suitable to promote planktonic growth inside capped PDMS-based microfluidic devices if the PEM deposition is completed by a dynamic flow-through process. 相似文献

During competition, kayak athletes must optimally adapt to environmental factors (e.g. wind, waves) to achieve peak performance. However, the ability to adapt to such perturbations has never been assessed in kayak paddling. Therefore, the aim of the current study was to evaluate the local dynamic stability in sports technique of youth sprint kayak athletes. In a cross-sectional study, 14 healthy male athletes were recruited from an elite youth sprint kayak squad. During an incremental kayak ergometer test, mean power, heart rates and local dynamic technique stability of hands, arms, trunk and paddle were registered and the association with the athletes 2000?m free-water times were estimated using mixed models. The 2000?m free-water performance significantly predicted the paddles (p?=?.037) local dynamic stability whereas no association was found for the trunk or the upper extremity kinematics. In conclusion, kayak athletes with high-performance capability over 2000?m paddling depict high local dynamic technique stability. This emphasizes the importance of a stable technique for advanced kayak skills, especially regarding paddling movements. 相似文献

Does Parent–Child Discussion of Peer Provocations Reduce Young Children's Hostile Attributional Bias? 下载免费PDF全文

Two studies investigated whether parent–child discussion of peer provocations reduces young children's hostile attributional bias. Study 1 (N = 109, age 4–7)—an observational study—showed that parent–child discussion of nonhostile attributions (when reading a picture book) predicted reductions in children's hostile attributional bias from pre‐ to postdiscussion. Study 2 (N = 160, age 4–6)—an experimental study—showed that stimulating parents to discuss either nonhostile attributions or normative beliefs (vs. a control condition) reduced children's hostile attributional bias in response to hypothetical vignettes, but not in response to a staged peer provocation. These findings suggest that by framing social situations, parents may help their children perceive less hostility in their social worlds. 相似文献

This paper reports a study on teachers’ domain‐specific beliefs about the chemistry curriculum for upper‐secondary education in The Netherlands. Teachers’ beliefs were investigated using a questionnaire focused on the goals of the chemistry curriculum. The design of the questionnaire was based on three curriculum emphases: ‘fundamental chemistry’, ‘chemistry, technology and society’, and ‘knowledge development in chemistry’. The questionnaire was administered to a sample of Dutch chemistry teachers. The results indicate that, on the whole, the curriculum emphasis ‘fundamental chemistry’ received the strongest support. This is in accordance with the content and the tradition of the Dutch chemistry curriculum. When the two types of upper‐secondary education were compared, it appeared that ‘chemistry, technology and society’ was almost equally valued for both types of education. However, the curriculum emphasis, ‘knowledge development in chemistry’, was considered much more important for pre‐university education than for senior general secondary education. 相似文献

The present investigation addresses the question of whether certain factors can protect high-achieving students at risk for being labeled a nerd against devaluation. In 2 studies, 125 and 317 students from Grade 8 evaluated vignettes describing average students and students who were called “nerds.” Results indicate that being modest about good grades, being engaged in sports, and being sociable led to higher liking. In students who were labeled nerds, but not in average students, display of effort led to less favorable evaluations. The effects of the aforementioned factors were moderated by the gender of the perceivers and targets. Findings are discussed with respect to gender-role stereotypes and the self presentation of high-achieving students. 相似文献
