This study examined whether differences in waist circumference (WC) and pedometer placement (anterior vs. midaxillary vs. posterior) affect the agreement between pedometer and observed steps during treadmill and self-paced walking. Participants included 19 pairs of youth (9–15 years old) who were matched for sex, race, and height and stratified by WC (high WC: HWC; low WC: LWC). Participants performed 3-min treadmill-walking trials at speeds of 59, 72, and 86 m·min-1 and a 400-m self-paced walking trial on level ground. Bland-Altman plots were used to assess the agreement between pedometer and observed steps of spring-levered pedometers by WC, pedometer placement, and walking speed. In the HWC group, the posterior pedometer placement consistently agreed most closely with observed steps at all treadmill speeds and during self-paced walking. In the LWC group, no single pedometer placement consistently agreed most closely with observed steps at all treadmill speeds and during self-paced walking. We conclude that a posterior pedometer placement improves step-count accuracy in most youth with an HWC at a range of walking speeds on level ground.  相似文献

ABSTRACT

In this paper, we draw on the ‘dilemma of difference’ to discuss the dangers and affordances of diagnosis within two of the most prevalent, yet under-supported, disabilities affecting school-age children: Attention Deficit Hyperactivity Disorder (ADHD) and Developmental Language Disorder (DLD). The dilemma that exists between denying and thereby ignoring difference on the one hand, versus recognising and potentially stigmatising difference on the other, will be explored and the consequences outlined. Our aim is to achieve a middle ground that conceives of diagnosis as a helpful starting point to enable educators to address barriers to access and participation through appropriate adjustments to curriculum, pedagogy and assessment.  相似文献

This study uses latent class analysis (LCA) to empirically identify victimization groups during middle school. Approximately 2,000 urban, public middle school students (mean age in sixth grade = 11.57) reported on their peer victimization during the Fall and Spring semesters of their sixth, seventh, and eighth grades. Independent LCA analyses at each semester yielded 3 victim classes based on victimization degree rather than type (e.g., physical vs. relational). The most victimized class always represented the smallest proportion of the sample, decreasing from 20% in sixth grade to 6% by the end of eighth grade. This victimized class also always reported feeling less safe at school concurrently and more depressed than others 1 semester later, illustrating the validity of the LCA approach.  相似文献

Abstract This paper explores the theory of “communities of practice” and how the ideas contained in it could be applied to museums, by demonstrating how a key stakeholder group, Indigenous people, have been involved with and engaged in the work of the Australian Museum, Sydney, over the past 30 years. It is suggested that the processes museums have developed in building relationships with Indigenous people, particularly at the practitioner level, could form a template for how museums make themselves relevant to broader communities through active engagement with multiple communities of practice.  相似文献

Students with Attention Deficit Hyperactivity Disorders (ADHD) frequently experience significant difficulty mastering basic academic skills. This meta‐analysis focuses on one specific potential area of learning difficulties for these students: namely, writing. To identify the extent and depth of the potential writing challenges faced by students with ADHD, we conducted a meta‐analysis comparing the writing performance of grade 1 to 12 students with ADHD to their normally achieving peers. We located 44 papers, yielding 45 studies with 87 effect sizes. The average weighted effect sizes showed that students with ADHD obtained lower scores than their normally achieving peers for writing quality (–0.78), output (–0.64), number of genre elements (–0.69), vocabulary (–0.76), spelling (–0.80), and handwriting (–0.62). Contrary to expectations, moderator analyses found that neither study quality nor the source from which ADHD students were drawn (i.e., school/community vs. clinic/hospital) accounted for variability above sampling error alone.  相似文献

We have undertaken a critical appraisal of the current English system of law regulating: (1) Provision of services designed to prevent children coming into care of local authorities, which are the authorised agencies for dealing with children who are abused or neglected. (2) Ways of receiving children into care and also ways of terminating care orders. We question whether, and under what circumstances, care orders are really necessary. (3) Periodic reviews of children in care. We are critical of the English system and look to models in the USA as guides towards the possible reform of English law. We take the same perspective when considering termination of parental rights. In our opinion good laws do not of themselves provide the care and love which a child requires, but they make the caring possible by loved and loving adults. We argue that the law must provide the best possible framework to allow adequate caring by members of the non-legal professions, such as social workers and foster parents. At the same time the law must ensure that the rights of parents and children are protected.  相似文献

Quantum chemistry is based on the solution of the Schrödinger equation for a molecule. From starting data on the positions and nature of constituent atoms information is provided about the energy of the molecule and its electronic properties. The former can indicate what shapes drugs can adopt in binding to pharmacological receptors whilst electronic details, when compared using computer graphics, may highlight the factors responsible for biological activity. These techniques are beginning to show real successes in the design of drug molecules.  相似文献

A random sample of 482 teachers in grades 3 through 8 from across the United States were surveyed about (a) their perceptions of the version of the Common Core writing and language standards adopted by their state and their state’s writing assessment, (b) their preparation to teach writing, and (c) their self-efficacy beliefs for teaching writing. Regardless of grade, a majority of teachers believed that the adopted standards are more rigorous than prior standards, provide clear expectations for students that can be straightforwardly translated into activities and lessons, and have pushed them to address writing more often. However, many surveyed felt the new writing and language standards are too numerous to cover, omit key aspects of writing development, and may be inappropriate for struggling writers. Moreover, most did not feel that professional development efforts have been sufficient to achieve successful implementation, and nearly one in five respondents was not familiar with the standards. The respondents were generally less sanguine regarding their state’s writing test, with elementary teachers even less positive than middle school teachers on some aspects, though nearly a third were unfamiliar with their state test. A majority believed state writing tests, though more rigorous than prior tests, fail to address important aspects of writing development, do not accommodate the needs of students with diverse abilities, and require more time than is available to prepare students. Additionally, many teachers believed professional development efforts have been insufficient to help them understand measurement properties of the assessments and how to use test data to identify students’ writing needs. Teachers who were better prepared to teach writing and who held more positive personal teaching efficacy beliefs for writing exhibited generally more positive perceptions of their state’s standards. In contrast, only teacher efficacy beliefs made a unique contribution to the survey respondents’ attitudes and beliefs about their state’s writing test.  相似文献

In recent years, the Standards for Qualified Teacher Status in England have placed new emphasis on student‐teachers' ability to become integrated into the ‘corporate life of the school’ and to work with other professionals. Little research, however, has been carried out into how student‐teachers perceive the social processes and interactions that are central to such integration during their initial teacher education school placements. This study aims to shed light on these perceptions. The data, gathered from 23 student‐teachers through interviews and reflective writing, illustrate the extent to which the participants perceived such social processes as supporting or obstructing their development as teachers. Signals of inclusion, the degree of match or mismatch in students' and school colleagues' role expectations, and the social awareness of both school and student‐teacher emerged as crucial factors in this respect. The student‐teachers' accounts show their social interactions with school staff to be meaningful in developing their ‘teacher self’ and to be profoundly emotionally charged. The implications for mentor and student‐teacher role preparation are discussed in this article.  相似文献

Government policy assumes that modernization and remodelling will be effective as external intervention mechanisms to improve job satisfaction. Based on data collected as part of the evaluation of the ‘Transforming the School Workforce Pathfinder Project’, an argument is presented here which suggests that internal management models may be more effective in improving teacher job satisfaction. By comparing the responses of teachers within primary and special schools with those from secondary schools, internal factors are identified which may be more relevant than externally imposed measures.  相似文献
