International exchange and training programs play a significant role in the development of international cooperation between educators from different nations. More and more teachers and school administrators participate in exchange programs and implement new curricular and instructional practices in their institutions. The objectives of this interpretive exploratory case study were (a) to investigate the impact of international exchange and training programs on pedagogical practices of Russian school teachers and administrators and (b) to find out how participants of international programs apply, implement, and transfer their experiences and knowledge that they obtain during their programs. The data were collected through personal interviews, observations, and materials from several debriefing sessions in 2005. The study demonstrated that the participation in international programs significantly impacts educators’ pedagogical practices, expands the range of their instructional approaches, makes program alumni more culturally sensitive and perceptive, and influences their interpersonal relations in schools, their professional growth, and social status. This research can be of interest to perspective participants of international programs and practitioners who develop and organize international programs for educators.  相似文献

This article proposes a theoretical framework of transcultural risk communication to examine how global connectivities influence communication about H1N1 flu. A case study was conducted to investigate risk management policies at global, regional, and translocal levels to cope with health threats posed by the emerging H1N1 flu epidemic. We explored how risk management approaches by Chinese Internet users facilitated the employment of a unique risk measure of exit and entry screening for returnees to China.  相似文献

辨析胡适语言观念的哲学内核,提炼胡适语言思想的进化观、实证观和实用观,梳理出一条以胡适的语言观念为内在逻辑的语言路线.即:从1917年开始的“白话文运动”,经过1920年代“文学研究会”,到1920年代末“文学研究会”分化出来的“开明作家群”和左翼作家茅盾的“社会剖析小说”,再到1930年代瞿秋白呼吁的“文腔革命”并进而推动的“大众语”讨论和“拉丁化运动”,最后到毛泽东发动的“延安整风运动”.或者更简练地说,从“胡适之体”到“毛文体”,客观上呈现出一条注重语言的实用性、工具性和规范化的胡适路线.  相似文献

幼儿故事在幼儿发展和幼儿园教学中起着非常重要的作用,不同的幼儿在不同的故事呈现方式中表现出不同的复述特点。本文采用多彩光谱语言评估标准,对从西安市市区4所不同类型幼儿园中获得的126份语言样本进行了分析。研究结果显示,图书组和录音组幼儿的故事复述能力差异不显著,视频组幼儿在故事复述能力测试中总体得分较低。尽管从总体上看,许多幼儿的复述能力处于同一水平,但构成复述能力的要素却存在较大的个体差异。不同幼儿在同一语言活动中复述故事的字数和语言特点各不相同。  相似文献

二语词汇一直处于学习的中心地位,但词汇学习的现状仍不容乐观.以频率为基础的二语习得观,强调频率对词汇学习的重要作用.本文从频率的角度出发探讨学习哪些词汇、怎样学习以及如何加强词汇输出,来实现提高词汇学习的能力、发展学习词汇的策略以及增强词汇运用能力的目的.  相似文献

写作反馈是读者向作者的输入,其目的是为作者修改文章提供信息,它具有评价、知识传递、促进学习的功能。写作反馈的理论基础主要包括语言输出假设、语言输入假设和二语习得整合理论。纵观国内近20年二语写作反馈研究成果,主要集中在书面反馈模式、反馈效果、影响反馈效果的因素三个方面。反馈模式主要有教师反馈、同伴反馈、教师与同伴反馈相结合模式、电子智能反馈模式四种。制约和影响反馈效果的因素主要有反馈接收者、反馈发出者和反馈方式三个方面。反馈效果是反馈研究最为关注的核心问题,反馈的最终目的在于使学生能够内化反馈的知识点。在远程教学中,由于教与学时空分离、学生基础薄弱、师生比例太大,这给远程写作教学带来新的挑战。构建一种"写作-反馈-内化"的写作反馈生态链是应对这一挑战的新思路。生态链中的"写作"不断输出学习者对语言知识的假设,"反馈"不断发现和修正学习者在语言学习过程中的错误假设,"内化"则不断地运用已有知识吸收语言知识的正确假设。通过不断循环,能够保证远程学习者语言学能和写作能力的不断提高。  相似文献

Abstract

Meaning lies at the core of intercultural communication. The ways in which meanings are made and the differences in meanings form a core problematic for intercultural communication. Yet intercultural communication theorists have yet to systematically explore the processes by which language and meanings converge and diverge within and across particular cultural milieus. The goal of the present analytical essay is to move the theory of language convergence/meaning divergence (LC/MD) into the intercultural communication realm. LC/MD processes discussed in the analysis include language convergence, meaning divergence through meaning clusters and meaning fragments, and the illusion of shared meanings. To illustrate ways in which LC/MD can be utilized by intercultural communication scholars, cults and morality as foreign policy are analyzed.  相似文献

Integrating knowledge across a firm's value chain (e.g. between R&D, marketing and manufacturing functions), which we denote “Knowledge Integration” (KI), has been consistently found to be a strong predictor of product innovation performance in the management literature. Such cross-functional integration does not occur by chance, but by design, as a result of managerial practices and organizational arrangements. The significant heterogeneity characterizing the diffusion of cross-functional integration across firms is suggestive of the well-known tension between internal and external diffusion of knowledge. In this paper, we argue that the hidden cost of KI is to expose firms to a higher risk of knowledge leakages and provide the first systematic empirical evidence of this apparent tension between internal and external knowledge flows. Based on data from the CMU Survey (one of the rare datasets offering observables on both sides of the tension for a representative set of R&D active firms in the US), we investigate the impact of knowledge spillovers to competitors on internal cross-functional knowledge integration involving the R&D function among manufacturing firms. We find that the intensity of (tacit) R&D knowledge spillovers at the industry-level has a negative and significant impact on the likelihood that firms adopt or achieve KI. Our results therefore suggest that firms may trade their optimal innovative performance against superior appropriability of their rents.  相似文献

A current challenge for the scientific community is the choice of appropriate policies to reduce the rate of false positives. Existing proposals differ in whether to prioritize tackling omission through transparency requirements, punishing more severe transgressions, or possibly both. We use a formal model to evaluate these possible solutions. We find that a policy that prohibitively increases the cost of ‘misdemeanor’ types of questionable research practices robustly decreases the overall rate of researcher misconduct, because the rate of ‘felonies’, such as fabrication, also decreases. Therefore proposals that aim to prevent lying by omission by enforcing reporting guidelines are likely to be effective in reducing researcher misconduct, but measures such as government audits (purported to counteract pure fraud) can backfire. Moreover, we find that an increase in the rewards of publication need not increase overall misconduct.  相似文献
