The trouble with transfer: insights from microgenetic changes in the representation of numerical magnitude 总被引：1，自引：0，他引：1
Spontaneous transfer of learning is often difficult to elicit. This finding may be widespread partly because pretests proactively interfere with transfer. To test this hypothesis, 7-year-olds' transfer was examined across 2 numerical tasks (number line estimation and categorization) in which similar representational changes have been observed. As predicted, children given feedback on numerical estimates learned to use a linear representation of numerical quantity instead of a logarithmic one, but providing practice on a categorization pretest led children to continue using a logarithmic representation on the same task, which they otherwise abandoned with surprising frequency. These findings imply unsupervised practice of inappropriate representations impedes transfer, and studies of learning can greatly underestimate children's potential for transfer if pretest effects are uncontrolled. 相似文献

Meaningful participation in science and engineering practices requires that students make their thinking visible to others and build on one another's ideas. But sharing ideas with others in small groups and classrooms carries social risk, particularly for students from nondominant groups and communities. In this paper, we explore how students' perceptions of classrooms shape their contributions to classroom knowledge building in science across a wide range of classrooms. We examine the claim that when students feel a sense of belonging in class, they contribute more and perceive their ideas to be more influential in knowledge building. Data comes from classroom exit tickets (n = 10,194) administered in 146 classrooms as part of a 10-state field test of a new middle-school science curriculum, OpenSciEd, which were analyzed using mixed effects models. We found that students' sense of belonging predicted the degree to which they contributed ideas out loud in class (Odds ratio = 1.57) as well as the degree to which they perceived their contributions as influencing others (Odds ratio = 1.53). These relationships were particularly strong for students who reported a lower a sense of belonging. We also found significant differences by both race and gender in whether students said they contributed and believed their ideas influenced those of others. These findings suggest that a learner's sense of belonging in class and willingness to contribute may be mutually reinforcing, highlighting the need to promote content-specific strategies to foster belonging in ways that support collaborative knowledge building. 相似文献

Studies have shown a positive relationship between a rise in schooling levels and economic production [World Bank, 2005. A Time to Choose: Caribbean Development in the 21st Century. World Bank, Washington, DC; Jules, V., Panneflek, A., 2000. EFA in the Caribbean: Assessment 2000, Sub-Regional Report, vol. 2, The State of Education in the Caribbean in the 1990s. UNESCO, Kingston, Jamaica; Haddad, W.D., 1990. Education and Development; Evidence for New Priorities. World Bank Discussion Paper 95. The World Bank, Washington, DC; McClelland, D., 1969. Does Education Accelerate Economic Growth. In: Eckstein, M.A., Noah, H.J. (Eds.), Scientific Investigations in Comparative Education. Macmillan, London], but this link may be limited in systems of education where traditional pedagogic methods have been dominant (such as the Caribbean islands of Trinidad and Barbados where underachievement is also associated with lack of participation and low levels of social inclusion skills by teachers: World Bank, 1992. Access, Quality and Efficiency in Caribbean Education: a Regional Study. World Bank, Washington, DC; Kutnick, P., Jules, V., Layne, A., 1997. Gender and School Achievement in the Caribbean. Department for International Development, London). Into traditional classroom contexts in Trinidad and Barbados, a new social pedagogic method was introduced by teachers and changes in attainment and motivation of pupils and attitudes of teachers were assessed over two terms in secondary schools. 相似文献

寒冷的12月,很多人都应该进入了冬眠或半冬眠状态,足不出户,舒舒服服地蜷缩在被窝里睡懒觉吧。但一些生活在北方的人偏要唱反调,在冰天雪地的户外进行传统的冬季运动——冬泳。这对长期生活在南方的Grace来说确实很不可思议。冬泳究竟有什么魅力,为什么能吸引这么多人参与呢?它对健康真的有那么多好处吗?想知道答案,一起看看本文作者在俄罗斯的冬泳经历。Grace提醒一下,想尝试冬泳的同学务必注意安全哦! 相似文献

Numerous studies are demonstrating that engaging undergraduate students in original research can improve their achievement in the science, technology, engineering, and mathematics (STEM) fields and increase the likelihood that some of them will decide to pursue careers in these disciplines. Associated with this increased prominence of research in the undergraduate curriculum are greater expectations from funders, colleges, and universities that faculty mentors will help those students, along with their graduate students and postdoctoral fellows, develop an understanding and sense of personal and collective obligation for responsible conduct of science (RCS). This Feature describes an ongoing National Research Council (NRC) project and a recent report about educating faculty members in culturally diverse settings (Middle East/North Africa and Asia) to employ active-learning strategies to engage their students and colleagues deeply in issues related to RCS. The NRC report describes the first phase of this project, which took place in Aqaba and Amman, Jordan, in September 2012 and April 2013, respectively. Here we highlight the findings from that report and our subsequent experience with a similar interactive institute in Kuala Lumpur, Malaysia. Our work provides insights and perspectives for faculty members in the United States as they engage undergraduate and graduate students, as well as postdoctoral fellows, to help them better understand the intricacies of and connections among various components of RCS. Further, our experiences can provide insights for those who may wish to establish “train-the-trainer” programs at their home institutions. 相似文献

Children (n = 130; M(age) = 8.51-15.68 years) and college-aged adults (n = 72; M(age) = 20.50 years) completed numerosity discrimination and lexical decision tasks. Children produced longer response times (RTs) than adults. R. Ratcliff's (1978) diffusion model, which divides processing into components (e.g., quality of evidence, decision criteria settings, nondecision time), was fit to the accuracy and RT distribution data. Differences in all components were responsible for slowing in children in these tasks. Children extract lower quality evidence than college-aged adults, unlike older adults who extract a similar quality of evidence as college-aged adults. Thus, processing components responsible for changes in RTs at the beginning of the life span are somewhat different from those responsible for changes occurring with healthy aging. 相似文献

How does understanding the decimal system change with age and experience? Second, third, sixth graders, and adults (Experiment 1: N = 96, mean ages = 7.9, 9.23, 12.06, and 19.96 years, respectively) made number line estimates across 3 scales (0–1,000, 0–10,000, and 0–100,000). Generation of linear estimates increased with age but decreased with numerical scale. Therefore, the authors hypothesized highlighting commonalities between small and large scales (15:100::1500:10000) might prompt children to generalize their linear representations to ever‐larger scales. Experiment 2 assigned second graders (N = 46, mean age = 7.78 years) to experimental groups differing in how commonalities of small and large numerical scales were highlighted. Only children experiencing progressive alignment of small and large scales successfully produced linear estimates on increasingly larger scales, suggesting analogies between numeric scales elicit broad generalization of linear representations. 相似文献
