汉英语言中都存在名词动词化现象,在现代英语中这一用法极为普遍;而汉语中这种用法则多出现于古代文学作品,现代汉语中出现较少。本文试图从名词动词化的概念、形成的动因和分类三方面进行分析,让中国的英语学习者加深对汉英语言中这一用法的了解和认识,从而能更多地欣赏到这一语言现象的简洁、灵动之美。  相似文献

良好动机的培养是幼儿教育的一项重要任务。幼儿所处的年龄阶段,使其行为动机呈现出单一性、低层次性以及失稳性等特点,幼儿常常出现固执、满足于简单的生理需要、在活动中注意力不集中和活动目标易转移等现象。要克服幼儿的这些不良现象,必须根据幼儿自身的特点,采取科学的方法,通过动机单一性向多元化的转换,低层级向高层级的转换,替换性向稳定性的转换,促进幼儿良好动机的形成与发展。  相似文献

在教育实践中,由于教师期望与价值追求不高、教师专业发展阶梯不完善等原因,影响了教师专业发展的动力。针对教师专业发展动力机制中存在的问题与不足,在多年的实践探索中,从建设个性校园文化、建立不同阶段教师个人发展阶梯、建立保障性管理制度、坚持师生教学相长、增加海外培训机会、推动教师专业交流等方面,不断激发教师专业发展的内在动力,帮助教师实现专业的持续发展,并就如何建立教师持续专业发展动力机制进行了一些思考。  相似文献

OBJECTIVE: To identify individual, family, and caseworker characteristics associated with problem recognition (PR) and intentions to change (ITC) in a sample of caregivers who received in-home child welfare services following substantiated reports of child abuse or neglect. METHODS: Caregivers were interviewed at 4 weeks, 16 weeks, and 1 year after referral for in-home services. In these interviews, the University of Rhode Island Change Assessment scale assessed PR and ITC in relation to caregiving practices. Additional data were obtained from administrative records and surveys of in-home services caseworkers. We used growth models to identify caregiver, family, and caseworker characteristics associated with initial levels of PR and ITC, and with changes in PR and ITC over time. RESULTS: Contrary to expectations, there were no overall increases in PR and ITC during the first 4 months of in-home services. PR and ITC scores fluctuated over time, in relation to some external events, case characteristics, and caseworker characteristics; however, we were able to account for small portions of the variance in PR and ITC. Controlling for social desirability bias and other variables in the analysis, negative life events, lack of network support, and the severity of caregiver depression were associated with greater PR; housing problems were associated with lower PR. Caregiver depression and age were associated with ITC. Caregivers whose children had been removed from their homes showed significant increases in ITC in the first few months of in-home services. The duration of caseworkers' child welfare experience predicted increases in their clients' PR in the first 4 months and more frequent contacts with an experienced caseworker predicted small, but significant increases in ITC over time. CONCLUSIONS: PR and ITC are associated with somewhat different case characteristics and may be affected by caseworkers' experience.  相似文献

Although a majority of seniors continue to express interest in using mobile social network sites (MSNSs), research has yet to provide sufficient understanding of this very large market’s motivations related to MSNS usage. As a viable consumer business segment, seniors are attractive enough to warrant potential MSNSs to invest necessary capital for developing tourism related MSNS designed to assist with this market’s decision making and ultimately with their purchasing behavior. To address this gap, a research model was developed for this study using seniors having used MSNSs for purposes directly related to tourism and travel. Findings revealed intrinsic motivations had stronger effects on flow experience than did extrinsic motivations. Flow experience was found to have the greatest effect on subjective well-being, which in turn highly influenced purchase intention. Results documented that senior MSNS users differed significantly according to levels of anxiety attachment. Findings provide theoretical and practical contributions for tourism research, products, and services regarding senior MSNS consumers.  相似文献

Based on self-determination theory, this research aimed at evaluating the effectiveness of the CASIS professional development (PD) program for fostering (1) teachers’ use of five recommended pedagogical practices during a writing lesson and (2) students’ motivational resources (intrinsic, identified, and controlled regulations) toward writing. Two quasi-experimental studies with two-time points were conducted among preservice (Study 1, n = 32) and inservice (Study 2, n = 111) elementary teachers and their students (Study 1, n = 559; Study 2, sample 1, n = 1779; sample 2, n = 1471). In both studies, the CASIS PD program appeared to foster the use of two of the five recommended pedagogical practices. For the other three, some effects were observed in one study but were not always reproduced in the other. Although the CASIS PD program fostered greater use of the pedagogical practices, this effect did not always translate directly to the students’ motivational resources. However, some significant differences were observed between students of the CASIS and the control groups on identified and controlled regulations, as a function of the socioeconomic background of the schools in which teachers and students were sampled. The results are discussed in light of past research and relevant theories.  相似文献

This study discusses the generalizability of gender differences in the second language competences of European adolescents across three languages, three skills and fourteen countries. In most cases, females do better than males but the effect sizes are small or medium at best (Cohen's ds < −0.46). However, English appears rather gender-neutral on average, with males sometimes outperforming females. We also found evidence for cross-skill variation: writing turns out to be more prone to gender differences than listening or reading. Thirdly, we found cross-country variation in the gender gap, which supports the hypothesis that gender is primarily a social factor rather than a biological factor in learning. Multilevel mediation analyses with constituents of motivation indeed show that in most cases where females outperform males, up to 60% of this advantage can be explained by the differential appeal of the students' L2 course and by the instrumental, integrative and intrinsic value that students attribute to the L2.  相似文献

This article introduces a new theoretical and psychometric framework describing moment-to-moment development and inter-dependencies of achievement motivation in terms of the situated expectancy-value theory, by introducing dynamical systems concepts into this line of research. As a first empirical example of a study using this framework, we examined whether task values, costs, and success expectancies measured in a learning situation (time point t) predicted themselves and each other at the next situation (t + 1; 27 min later) within a weekly university lecture.Situational task values, expectancies, and costs were assessed using the experience sampling method in 155 university teacher training students during weekly lectures for one semester, with three surveys during each weekly lesson. Data were analyzed with multilevel cross-lagged structural equation models.There were significant auto-regressions from one learning situation to the next in success expectancies and effort costs, but not in intrinsic, utility, or attainment value nor emotional or opportunity costs. There were no significant cross-lagged effects from one situation to the next in any of the measured situated expectancy-value components.As a framework to integrate dynamical systems concepts into the research on situated learning motivation, we expect the proposed DYNAMICS framework to have a substantial impact on further theory development.  相似文献
