Some people think that science is a set of facts that can be presented in plain and unadorned language. This fosters a belief that science has few stories. Actually, stories are very important in school science. In an examination of science textbooks, I have identified four different types of science stories which I call (a) heroic, (b) discovery, (c) declarative, and (d) politically correct. Each of these types of story promotes a particular set of philosophical assumptions about science. These assumptions are presented implicitly within the framework of the story as truths of science. This article specifically examines the philosophical assumptions that underpin heroic science stories and the implications of these stories in the discursive practices of the school science classroom. As teachers, we need to be critically aware of these assumptions, since they may be at odds with our beliefs about knowledge and our preferred teaching practices. © 1998 John Wiley & Sons, Inc.

A conceptual framework of positions on women in science, engineering, and technology (SET) was developed, showing a chronological progression of the main approaches to women's underrepresentation in SET during the past 20 years. Numerous initiatives have been advocated to address women's underrepresentation in SET in higher education. This article arose out of one such initiative, Winning Women, which was intended to help higher education in Scotland move toward good practice in this field. Two members of the project team describe their key findings and experiences. They illustrate how the underrepresentation of women in SET continues to be both progressive and persistent (using an SET parity index). The conceptual framework was conceived and developed from a metaanalysis of feminist theories of the gendered politics of science and technology. © 1999 John Wiley & Sons, Inc.

A model of hyperkinesis is introduced based on an ecological conception. The antecedents of hyperkinetic behavior are provided by a child's family environment, academic environment, and physiologic environment. These factors influence cognitive processes of the child. The consequences of hyperkinetic behavior often are undesirable, and so professional treatment is sought. Based on the ecological approach, effective treatment is multimodal and can involve the child, the family, and the school. No single approach to treatment is effective with all children. 相似文献

The objective of this review was to determine the direction and strength of the prospective relationship between social support and PA among healthy adults. A systematic review was conducted; including studies up until December 2015, in the following databases: Ovid MEDLINE, EMBASE, PsychINFO, SPORTDiscus, and Scopus. Published English and French written studies were included if the reported study used a longitudinal design; examined the relationship between social support and PA over at least two intervals; and assessed a sample of healthy adults between 18–65 years of age. Two reviewers independently extracted study information and independently assessed the risk of bias in each study. The initial search yielded a total of 2892 citations, and 20 studies were included in the review. Follow-up period ranged from 2 weeks to 10 years. Irrespective of the type and source of support, the strength and direction of the association between social support and PA was inconsistent across studies, with effect sizes ranging from small to large and from negative to positive. Based on meta-analysis, there was a small positive association between support for PA from friends and future PA. Researchers are encouraged to continue to conduct longitudinal studies to better understand the relationship between social support and PA. 相似文献

In many multicultural democracies, education has a Christian history. However, teaching religion has ideological variation. Progressives teach about many religions, while conservatives favor (often exclusive) instruction into one tradition. Australian secular education controversially prioritizes faith-forming instruction (mostly Christian). In this exploratory study (N = 123) the author examines pedagogical preference and attitudes toward religious diversity. 相似文献

The study tested the effect of aerobic exercise training on executive function in overweight children. Ninety-four sedentary, overweight but otherwise healthy children (mean age = 9.2 years, body mass index 85th percentile) were randomized to a low-dose (20 min/day exercise), high-dose (40 min/day exercise), or control condition. Exercise sessions met 5 days/week for 15 weeks. The Cognitive Assessment System (CAS), a standardized test of cognitive processes, was administered individually before and following intervention. Analysis of covariance on posttest scores revealed effects on executive function. Group differences emerged for the CAS Planning scale (p = .03). Planning scores for the high-dose group were significantly greater than those of the control group. Exercise may prove to be a simple, yet important, method of enhancing aspects of children's mental functioning that are central to cognitive and social development. 相似文献

For many years, pedagogical scholars and physical education (PE) teachers have worked to enhance effective teaching and learning environments. Yet for some children, youth, and young adults, many of the benefits associated with a physically active lifestyle remain elusive. Enhancing programming and performance to meet physical activity goals may require moving programs beyond “effective.” It will require teachers and program leaders to focus programmatic attention on strategies to actually increase students’ out-of-class physical activity behavior. Transformative PE provides physical activity content within a nurturing and motivating environment that can change students’ lives. It focuses on PE students’ role in cognitive decision making, self-motivation, and their search for personal meaning that can add connection and relevance to physical activities. In this SHAPE America – Society of Health and Physical Educators Research Quarterly for Exercise and Sport Lecture, I have synthesized the research on these topics to emphasize useful findings applicable to teachers’ everyday planning and teaching. Using sport, physical activity, dance, and adventure activities as the means to an end for personal and social growth, we can meet our commitment to effective standards-based education while preparing students for a lifetime of physical activity. 相似文献

This article builds on Yuval-Davis’s (2006, 2007, 2011) theories of belonging, in order to relay how practitioners can support unaccompanied asylum-seeking children (UASCs) in developing a positive sense of belonging in educational spaces in England. To do so, the article synthesises literature surrounding theories of belonging, UASCs’ educational access in England and practices supporting UASCs’ educational attainment and sense of belonging. Further, the article considers interviews with a social worker, English for speakers of other languages (ESOL) teacher, charity sector staff member, legal expert and government workers in East England, all of whom work with UASCs. Interview analysis seeks to understand how practitioners believe UASCs find a sense of belonging in the educational spaces that they inhabit. After presenting the interview findings, the article builds on scholarly literature related to supporting UASCs’ education by discussing how practitioners, including all staff who interact with UASCs in school, college or residential accommodation spaces, can work to facilitate UASCs’ sense of belonging in educational spaces in England. The article recognises that practitioners can do so through learning to speak with low-level ESOL students, developing trauma awareness and reflexively approaching their relationships with UASCs. Thus, the article provides policy recommendations to support practitioners in doing so. 相似文献

ABSTRACT The effects of acute ingestion of nitrate on short-duration repeated sprint performance (RSP) are unclear. This study investigated the effect of acute ingestion of beetroot juice on a test of RSP in team sport athletes. Sixteen male team sport athletes undertook four trials using a 40 m maximum shuttle run test (MST), which incorporates 10 × 40 m shuttle sprints with 30 s between the start of each sprint. Two familiarisation trials, followed by nitrate-rich beetroot juice (BR; ~6 mmol nitrate) and nitrate-depleted beetroot juice (PLA; ~0.0034 mmol nitrate) trials were completed in a randomised, double-blind manner. Ingestion of beetroot juice 3 h prior to exercise elevated plasma nitrate concentrations ~6-fold in BR (BR, 413 ± 56 μM; PLA, 69 ± 30 μM; P < 0.001). RSP, assessed by sprint performance decrement (Sdec; %), did not differ (P = 0.337) between BR (5.31 ± 2.49%) and PLA (5.71 ± 2.61%). There was no difference between trials for total sprint time (P = 0.806), fastest sprint (P = 0.341), slowest sprint (P = 0.787), or post-exercise blood lactate concentration (BR, 11.8 ± 2.5 mM; PLA, 12.2 ± 2.3 mM; P = 0.109). Therefore, acute ingestion of beetroot juice did not improve a test of short-duration RSP in team sport athletes. 相似文献
