根据国内外近期对学习策略的研究,学生的语言水平和学习策略的运用密切相关.英语阅读学习中主要应用到认知和元认知策略,这两种策略在是学生语言学习中使用频率较低,范围较窄.因此加强认知和元认知策略训练对于提高英语阅读水平是非常必要的. 相似文献

Do academic journals favor authors who share their institutional affiliation? To answer this question we examine citation counts, as a proxy for paper quality, for articles published in four leading international relations journals during the years 2000–2015. We compare citation counts for articles written by “in-group members” (authors affiliated with the journal’s publishing institution) versus “out-group members” (authors not affiliated with that institution). Articles written by in-group authors received 18% to 49% fewer Web of Science citations when published in their home journal (International Security or World Politics) vs. an unaffiliated journal, compared to out-group authors. These results are mainly driven by authors who received their PhDs from Harvard or MIT. The findings show evidence of a bias within some journals towards publishing papers by faculty from their home institution, at the expense of paper quality. 相似文献

Students with developmental disabilities are being increasingly included in college life. As this occurs, academic libraries will be providing more services to this population. This discussion of services to users with developmental disabilities attempts to help fill a gap in the literature and provide information that can be useful for libraries to build on as they develop services. Furthermore, by focusing on students with developmental disabilities, there are opportunities to improve services for all students. 相似文献

The present study examines bias in parameter estimates and standard error in cross-classified random effect modeling (CCREM) caused by omitting the random interaction effects of the cross-classified factors, focusing on the effect of a sample size within cells and ratio of a small cell. A Monte Carlo simulation study was conducted to compare the correctly specified and the misspecified CCREM. While there was negligible bias in fixed effects, substantial biases were found in the random effects of the misspecified model depending on the number of samples within a cell and the proportion of small cells. However, in the case of the correctly specified model, no bias occurred. The present study suggests considering the random interaction effects when conducting CCREM to avoid overestimation of variance components and to calculate an accurate value of estimation. The implications of this study are to illuminate the conditions of cross-classification ratio and to provide a meaningful reference for applied researchers using CCREM. 相似文献

中国农村工资性就业教育收益率的估计 总被引:1,自引:0,他引:1
根据CHIP农村住户调查数据,估算了1995、2002、2007年中国农村工资性就业的教育收益率。OLS估计表明1995-2007年农村全体打工者的教育收益率在3%-4%之间,呈轻微的下降趋势。在纠正了能力偏误和样本选择偏差之后,从2002年到2007年,全体打工者的教育收益率从3.2%下降到2.6%,本地打工者的教育收益率从3.5%下降到2.0%,外出打工者的教育收益率从不显著上升到4.5%。此外,教育水平的提高有助于促进农村劳动力从农业生产转向工资性就业,特别是转向本地的工资性就业。 相似文献

认知语境与交际失误 总被引:1,自引:0,他引:1

语境对交际的影响是两方面的。一方面,只有在语境中言语的交际才具有可能性;另一方面,语境制约或阻碍着交际的顺利进行,从而引起交际失误。 相似文献

Static word embeddings (SWE) and contextualized word embeddings (CWE) are the foundation of modern natural language processing. However, these embeddings suffer from spatial bias in the form of anisotropy, which has been demonstrated to reduce their performance. A method to alleviate the anisotropy is the “whitening” transformation. Whitening is a standard method in signal processing and other areas, however, its effect on SWE and CWE is not well understood. In this study, we conduct an experiment to elucidate the effect of whitening on SWE and CWE. The results indicate that whitening predominantly removes the word frequency bias in SWE, and biases other than the word frequency bias in CWE. 相似文献

生态心理学取向的情境观形成了不同于行为观和认知观的知识观、学习观和教学观.导致我们对人类学习的认识发生根本性变革的是这种基于情境的学习观,而不是建构观。虽然情境观有可能融合了行为观和认知观,但行为观和认知观同样有其实践的价值. 相似文献

从语境要素中的上下文、言语交际发生的行为环境及场景和认知环境三个方面来探讨话语的语境意义及其动态特征,并证实语境在语言中是动态的而不是静态的,对理解和推导话语含义具有指导作用。 相似文献
