For some international students, teachers' nonverbal immediacy may constitute a violation of expectations in classroom behavior. Using Expectancy Violation Theory framework, this study investigated differences in students ‘perceptions of teachers’ nonverbal immediacy by comparing American and international students studying in the U.S. The findings confirmed that (1) teachers' nonverbal immediacy is perceived as more appropriate by American students than by international students, (2) there are differences in evaluations of specific nonverbal immediacy behaviors by American students and international students, and (3) perceptions depended on student gender for some behaviors, but not teacher's gender. Learning was more positively related to perceived immediacy behaviors for international students than their American counterparts.  相似文献

This review examines contemporary issues in vocational development with emphasis on adolescents' work experiences in social context. Attention is directed to the changing social and cultural context for vocational development, the influence of work experience on adolescent development and educational achievement, and theoretical approaches that guide contemporary studies of vocational development and career maturity. In light of the utility of current theories, new directions are suggested to enhance understanding of adolescent employment, vocational development, and educational pursuits. Social policy initiatives to promote adolescents' exercise of agency and their vocational development are considered.  相似文献

Responses to an unfamiliar adult were examined in infants of mothers with social phobia ( N = 79) and infants of nonanxious comparison mothers ( N = 77) at 10 and 14 months in a social referencing paradigm. On each occasion, a female stranger first interacted with the mother and then approached and interacted with the infant. Over time, infants of mothers with social phobia showed increasing avoidance of the stranger, particularly when they were behaviorally inhibited. In boys, maternal social phobia was associated with increasing fearful responses. Infant avoidance was predicted by expressed maternal anxiety and low levels of encouragement to interact with the stranger. The findings are discussed in relation to theories concerning the intergenerational transmission of social anxiety.  相似文献

教学气氛用来描述在特定的教学空间中发生的课堂情绪.教学气氛的主要特点是双重性,它既是教学的手段又是教学的目的;既是影响教学的主体,也是被影响的客体;它具有半即兴性的性质.教学气氛美是教学美的一种表现形式,具有感性和理性和谐的特性,能调动学生的学习动力,富有新意并且需要教师和学生共同创造和维持.教学气氛美是发展学生核心素养的重要途径,它让学习更有意义,增加迁移的可能性,提高学生对学习的兴趣,完善学习状态,从而培养学生的终身学习能力,提高学生的创造力.  相似文献

The Developing Inclusive Youth program is a classroom-based, individually administered video tool that depicts peer-based social and racial exclusion, combined with teacher-led discussions. A multisite randomized control trial was implemented with 983 participants (502 females; 58.5% White, 41.5% Ethnic/racial minority; Mage = 9.64 years) in 48 third-, fourth-, and fifth-grade classrooms across six schools. Children in the program were more likely to view interracial and same-race peer exclusion as wrong, associate positive traits with peers of different racial, ethnic, and gender backgrounds, and report play with peers from diverse backgrounds than were children in the control group. Many approaches are necessary to achieve antiracism in schools. This intervention is one component of this goal for developmental science.  相似文献

Circulating tumor cells (CTCs) are important biomarkers for monitoring tumor dynamics and efficacy of cancer therapy. Several technologies have been demonstrated to isolate CTCs with high efficiency but achieve a low purity from a large background of blood cells. We have previously shown the ability to enrich CTCs with high purity from large volumes of blood through selective capture in microvortices using the Vortex Chip. The device consists of a narrow channel followed by a series of expansion regions called reservoirs. Fast flow in the narrow entry channel gives rise to inertial forces, which direct larger cells into trapping vortices in the reservoirs where they remain circulating in orbits. By studying the entry and stability of particles following entry into reservoirs, we discover that channel cross sectional area plays an important role in controlling the size of trapped particles, not just the orbital trajectories. Using these design modifications, we demonstrate a new device that is able to capture a wider size range of CTCs from clinical samples, uncovering further heterogeneity. This simple biophysical method opens doors for a range of downstream interventions, including genetic analysis, cell culture, and ultimately personalized cancer therapy.  相似文献

A large number of American elementary school students are now studying science using the hands‐on inquiry curricula developed in the 1990s: Insights; Full Option Science System (FOSS); and Science and Technology for Children (STC). A goal of these programs, echoed in the National Science Education Standards, is that children should gain “abilities to do scientific inquiry” and “understanding about scientific inquiry.” We have studied the degree to which students can do inquiries by using four hands‐on performance assessments, which required one or three class periods. To be fair, the assessments avoided content that is studied in depth in the hands‐on programs. For a sample of about 1000 fifth grade students, we compared the performance of students in hands‐on curricula with an equal number of students with textbook curricula. The students were from 41 classrooms in nine school districts. The results show little or no curricular effect. There was a strong dependence on students' cognitive ability, as measured with a standard multiple‐choice instrument. There was no significant difference between boys and girls. Also, there was no difference on a multiple‐choice test, which used items released from the Trends in International Mathematics and Science Study (TIMSS). It is not completely clear whether the lack of difference on the performance assessments was a consequence of the assessments, the curricula, and/or the teaching. © 2006 Wiley Periodicals, Inc.

Interpersonal neural synchrony (INS) has been previously evidenced in mother–child interactions, yet findings concerning father–child interaction are wanting. The current experiment examined whether fathers and their 5- to 6-year-old children (N = 66) synchronize their brain activity during a naturalistic interaction, and addressed paternal and child factors related to INS. Compared to individual problem solving and rest, father–child dyads showed increased INS in bilateral dorsolateral prefrontal cortex and left temporo-parietal junction during cooperative problem solving. Furthermore, the father’s attitude toward his role as a parent was positively related to INS during the cooperation condition. These results highlight the implication of the father’s attitude to parenting in INS processes for the first time.  相似文献

With regard to improving higher education feedback practices, there is an increasing interest in using the efficacy of dialogue rather than the more traditional unidirectional approaches. We build on this impetus by considering how the ethics of care can be used to analyse the dialogical aspects of feedback. By diffractively reading insights of Boud and Molloy [2013a. “What is the Problem with Feedback?” In Feedback in Higher and Professional Education: Understanding it and Doing it Well, edited by D. Boud, and E. Molloy, 1–10. London: Routledge; Boud, D., and E. Molloy. 2013b. “Rethinking Models of Feedback for Learning: The Challenge of Design.” Assessment &; Evaluation in Higher Education 38 (6): 698–712] on dialogic feedback through the moral elements of care ethics, this paper proposes a novel way of discerning the extent to which the dialogical giving and receiving of feedback contributes to learning. To illustrate this, we draw on experiences from an Emerging Technologies professional development course for higher educators. We examine our own dialogical interactions of giving and receiving feedback using the moral elements of care ethics – attentiveness, responsibility, competence, responsiveness and trust, to provide a concrete example of how the ethics of care can be used productively for evaluating feedback practices.  相似文献
