Research Findings: Quality early science education is important for addressing the low science achievement, compared to international peers, of elementary students in the United States. Teachers’ beliefs about their skills in a content area, that is, their content self-efficacy is important because it has implications for teaching practice and child outcomes. However, little is known about how teachers’ self-efficacy for literacy, math and science compare and how domain-specific self-efficacy relates to teachers’ practice in the area of science. Analysis of survey and observation data from 67 Head Start classrooms across eight programs indicated that domain-specific self-efficacy was highest for literacy, significantly lower for science, and lowest for math. Classrooms varied, but in general, engaged in literacy far more than science, contained a modest amount of science materials, and their instructional support of science was low. Importantly, self-efficacy for science, but not literacy or math, related to teachers frequency of engaging children in science instruction. Teachers’ education and experience did not predict self-efficacy for science. Practice or Policy: To enhance the science opportunities provided in early childhood classrooms, pre-service and in-service education programs should provide teachers with content and practices for science rather than focusing exclusively on literacy.  相似文献

Abstract

Social determinants of health are the key to understanding and addressing persistent disparities in adolescent pregnancy in the United States. However, there is little guidance on what concrete steps organizations can take to work at the intersection of social determinants of health (SDoH) and sexual and reproductive health (SH). Two community-based organizations completed a case study using a structured interview guide to illustrate their transition working at this intersection. The Alexandria Campaign on Adolescent Pregnancy and Identity, Inc. arrived at the intersection of SDoH and SH from opposite ends of the road. Despite clear differences in their trajectory, their experiences share four key elements that marked their success in expanding their core work: (a) both organizations enjoyed ample community and political support, (b) they used data to drive strategic decisions, (c) they used funding opportunities to move toward the intersection of sexual health and social determinants, and (d) they leveraged existing programs to sustain their efforts. Organizations working at the intersection must continuously leverage community, political, and financial capital to pursue partners, expand services, and change policies that sustain a holistic approach to youth health and well-being.  相似文献

A review of education policy and practice indicates a paradox in policy implementation. Policy outcomes most often differ significantly from intended purposes and provisions enacted. This paper re-conceptualises this policy phenomenon, drawing on the post-modernist conception of policy as both ‘text’ and ‘discourse’ as an approach for understanding and unmasking the messiness and contested nature of education policy processes. The choice of approach is based on three factors. First, the choice is grounded in its efficacy in explicating and legitimatising the issues of power within the policy arena. Second, the choice is based on the potential of the approach in integrating social and political theories of discourse with more linguistically oriented approaches to the study of policy. Third, the preference of approach follows from its potential to draw on language as a resource for reading into and/or analysing complex social issues.  相似文献

This paper examines the existing literature on new technology-based firms in an attempt to understand how such companies contribute to the vitality of an economy and to see which variables are critical in enabling them to do so. From recent research efforts, we have drawn together a set of hypotheses and organized them around four central questions: (1) What do new firms contribute to the economy? (2) What factors contribute to the success of such enterprises? (3) In what cultural contexts do new businesses succeed? and (4) Which government policies are effective in stimulating and supporting new companies? We found that existing studies suggest (1) that new technology-based firms contribute significantly to an economy in terms of exports, employment, taxes paid, research and development, and innovations; (2) that the founders of these new businesses tend to have a strong entrepreneurial heritage, a development- rather research-oriented background, and a high need to achieve and are young and highly educated; (3) that sector differences may be a more important influence on company location than are regional policies; and (4) that no one government program has proven itself to be more than marginally successful in stimulating industrial innovation.  相似文献

Children's literacy skills are an important predictor of success in the early elementary grades. Education programs for at-risk preschool students target children's acquisition of specific literacy skills, including knowledge of letters of the alphabet, in preparing children for early school success. Writing has been proposed as a complementary approach to other instructional strategies for teaching young children about letters. This study examines relations among preschool children's early writing competence, knowledge of letter names, sensitivity to initial sounds in words and understanding of print concepts in a sample of low-income children enrolled in Head Start. Data were collected from the beginning to the end of the school year, which offered the opportunity to examine concurrent development of these early literacy skills. Results revealed that children whose writing was more sophisticated knew the names of more letters, understood more about print concepts and were more sensitive to initial sounds of words. There was evidence of bidirectional influences of writing on growth in letter knowledge, and of letter knowledge on growth in writing competence.  相似文献

The introduction of widespread school Internet access in industrialised countries has been accompanied by the materialisation of what can be labelled as a national school e-safety agenda. Drawing upon Foucault's notions of discourse and governmentality, this paper explores how e-safety policy documents serve to constrain the conceptual environment, seeking to determine and limit individuals' thoughts on this matter. Analysing UK and US government texts, it is argued that four main themes arise that subvert critical, informed debate about children online. Namely, the discursive construction of e-kids, the muting of schoolchildren's voices, the responsibilisation of students and ‘diagnostic inflation’ through realist risk discourses. These issues can be interpreted as an attempt to engender control through particular strategies of governmentality. While recognising that students may resist such attempts at control, it is concluded that the issue of children's digital rights need to be more prominent in e-safety policies.  相似文献

This study examines associations between individual racism, anticipatory racism-related stress, and anti-racism activism among Black adolescents (n = 443; Mage = 15.6; 57.4% female) and emerging adults (n = 447; Mage = 23.8; 77.6% female). The authors tested competing hypotheses about associations between individual racism and anti-racism activism on anticipatory racism-related stress. Findings indicated anticipatory racism-related stress may be both a catalyst and consequence of engagement in anti-racism activism for Black adolescents and emerging adults. Results for each age group varied by type of stress (physiological; psychological) and activism (low-risk; high-risk). Supporting youth engagement in anti-racism activism without increasing anticipatory racism-related stress is a key priority for meaningfully advancing scholarship on the development of anti-racism and pursuit of racial justice.  相似文献
