The refugee sanctuary movement in the United States has shifted to include undocumented immigrants fleeing violence and economic strife. Given the negative tenor of coverage of undocumented immigration, and ties between framing and policy views on immigration, how the media frames sanctuary cities is likely to impact public perceptions of these cities and their policies. To assess media coverage of sanctuary policies, we analyzed articles from five national newspapers from 1980 to 2017 with both human content analysis and dictionary-based computational analysis. We find that framing around religion/morality and conflict has decreased, while stories focusing on crime and partisanship have increased. We discuss implications for public opinion and the likelihood that the American public will take their cues from media framing and elite discourse when it comes to sanctuary policies. 相似文献

In the United States today, urban schools serve the majority of high-poverty and high minority populations including large
numbers of Hispanic students. While many Hispanic students perform below grade level in middle school science, the science
teaching community as a whole is lacking elements of diversity as teachers struggle to meet the needs of all learners. Researchers
have recognized that science teacher effectiveness, one consequence of self-efficacy among teachers, is associated with future
science achievement and science-related careers of their students. This qualitative study explores how three science teachers’
effectiveness in the classroom impacts students’ science self-efficacy beliefs at one urban middle school. Hispanic students
were the focus of this investigation due to demographics and history of underperformance within this district. Teachers’ perspectives,
as well as outside observer evaluations of instructional strategies and classroom climates were triangulated to explore dynamics
that influence students’ interests and motivation to learn science using a framework to link teachers’ sense of efficacy (focusing
on student outcomes). Findings suggest the impact teacher effectiveness can have on student outcomes, including strengthened
student science self-efficacy and increased science achievement. Building awareness and support in teachers’ sense of efficacy,
as well as developing respectful and supportive relationships between educator/facilitator and pupil during the transition
to middle school may construct permanence and accomplishment for all in science. 相似文献

This article offers a critique of Michael Young’s perspective on the Internet as it relates to the knowledge-driven curriculum he supports. I argue that the Internet is a site of both theoretical knowledge and everyday concepts which challenges the differentiation of knowledge that premises much of Young’s writing. Google searches from the perspective of a student and teacher show that theoretical knowledge with vertical links to subject and disciplinary communities as well as coherence built through links between concepts is fairly readily accessed on the Internet. The importance of information literacy for students, the critical need to curate content on the web, as well as the implications for the curriculum of framing ‘knowing’ as encompassing ‘being familiar’ and comprehending’ are highlighted. 相似文献

In the Australian context, children living in disadvantaged circumstances, whose second language is English, are one of the groups at risk of failing in mathematics. This paper explores the impact purposely developed learning activities (Representations, Oral Language and Engagement in Mathematics Learning activities) have on pupils' mathematics outcomes in the first three years of formal schooling (Foundation, Year 1 and Year 2). The participating group (n = 461) comprised 328 English language learners and 133 mainstream pupils. To ascertain the impact of the learning experience, pre- and post-tests were conducted at the commencement and completion of each school year. The results indicate that all of the children significantly improved, with English as a second language pupils showing the greatest gains, and achieving norm-referenced expectations for their age. 相似文献

Developmental Differences in Relations Between Episodic Memory and Hippocampal Subregion Volume During Early Childhood 下载免费PDF全文

Episodic memory shows striking improvement during early childhood. However, neural contributions to these behavioral changes are not well understood. This study examined associations between episodic memory and volume of subregions (head, body, and tail) of the hippocampus—a structure known to support episodic memory in school‐aged children and adults—during early childhood (n = 45). Results revealed significant positive relations between episodic memory and volume of the hippocampal head in both the left and right hemispheres for 6‐ but not 4‐year‐old children, suggesting brain–behavior relations vary across development. These findings add new information regarding neural mechanisms of change in memory development during early childhood and suggest that developmental differences in hippocampal subregions may contribute to age‐related differences in episodic memory ability. 相似文献
