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

The Franklin Institute, Philadelphia, Pennsylvania, awards the 2010 Benjamin Franklin Medal in Computer and Cognitive Science to Professor Shafrira Goldwasser for fundamental work contributing to the theoretical foundation of modern cryptography and leading to techniques that mathematically guarantee secure access to the internet. More precisely, she is recognized for key contributions in provable security and in particular for interactive and zero-knowledge proofs and their application to cryptography and complexity theory. 相似文献

The authors of this study assess the attitudes and perceptions of academic librarians at three university libraries in China regarding library services for international students and scholars. The study directs particular focus on librarians at Shaanxi Normal University in Xi’an, Fudan University in Shanghai, and Wuhan University of Technology, China, and follows logically upon a study conducted in 2008 that explored the perceptions of international students at two Chinese universities regarding the effectiveness of library services and collections for their research needs. In particular, this study documents information about Chinese academic librarian perceptions regarding services for international students and attitudes toward future outcomes. The ultimate goal of the study is to lay a foundation for developing strategies for improving library services and resources for international students and scholars in Chinese academic libraries in particular, which in turn can serve to improve services for international students world-wide. The results support the assumption that academic librarians in China are strongly interested in improving services for international students and scholars while continuing to face challenges and trying to find ways to fulfill the information needs of international students and scholars. 相似文献

Project GRAD (Graduate Ready for Activity Daily) evaluates a university course to promote physical activity. In a randomized study, 338 university seniors participated in either an intervention or control course for academic credit, and posttest data were collected on 321. The control course was knowledge-oriented. The intervention course taught behavior change skills in weekly lectures and peer-led labs. Physical activity was assessed with 7-Day Physical Activity Recall interviews. The intervention had no significant effects on men. Among women, the intervention increased total physical activity during leisure, strengthening exercises, and flexibility exercise. This university course had the intended effects of promoting healthful patterns of physical activity among women, but no effects were observed on men, who were more active than women at baseline. 相似文献

In Canada, child care for kindergartners typically combines part-day school and child care. Exploratory research examined parents', teachers', and child care staff views on coordination between these programs. Community-based research surveyed these three groups. There was general agreement, and some key differences, among the groups in priorities for programs for kindergarten-age children. Social and language skills were generally considered most important; reading and writing least. Parents were particularly enthusiastic about a coordinated, school-based program. Teachers and child care staff were somewhat less enthusiastic about the model, with teachers' reactions the least positive. Teachers' views on the advisability of an integrated program were varied—some thought it would be of benefit to children, others disagreed. All three groups felt that a coordinated program would benefit by being school-based. Direct experience with integrated programs seemed to produce strong opinions about the value of program integration, with those teachers who had on-site child care programs giving the integrated programs the highest and the lowest ratings. Arguments are made for small-scale demonstration programs to expand provision of child care services using kindergarten as a foundation—and for rigorous evaluation of program impacts and outcomes. 相似文献

Students with disabilities typically experience academic, social, and behavioural challenges in school. Some of these students also often experience anxiety and stress associated with school situations and events. Wearable technologies are an emerging innovation in the United States that can support students with disabilities during stressful academic or social situations. This article discusses issues associated with wearables, offers questions to consider when considering a wearable device for a student, and describes several wearable technologies for students with disabilities. 相似文献

The aim of the study was twofold, namely (i) to determine the prevalence of symptoms of common mental disorders (CMDs) among current and retired professional football and handball players and (ii) to explore the relationship of psychosocial stressors with the outcome measures under study. A total of 1155 players were enrolled in an observational study based on a cross-sectional design. Questionnaires based on validated scales were set up and distributed among current and retired professional football and handball players by the Danish football and handball players’ union. In professional football, the highest prevalence (4 weeks) of symptoms of CMDs was 18% and 19% for anxiety/depression among current and retired players, respectively. In professional handball, the highest prevalence (4 weeks) of symptoms of CMDs was 26% and 16% for anxiety/depression among current and retired players, respectively. For both the current and retired professional football and handball players, a higher number of severe injuries and recent adverse life events (LE) were related to the presence of symptoms of CMD. Players exposed to severe injuries and/or recent adverse LE were 20–50% times more likely to report symptoms of CMD. The results suggest that it is possible to recognize the population of professional athletes that are more likely to develop symptoms of CMD. This could create the opportunity to intervene preventively on athletes that suffered from severe injury and/or recent adverse LE that could lead to a faster and safer recovery and psychological readiness to return to play. 相似文献
