The relationship between physical fitness and academic achievement has received much attention owing to the increasing prevalence of children who are overweight and unfit, as well as the inescapable pressure on schools to produce students who meet academic standards. This study examined 259 public school students in third and fifth grades and found that field tests of physical fitness were positively related to academic achievement. Specifically, aerobic capacity was positively associated with achievement, whereas BMI was inversely related. Associations were demonstrated in total academic achievement, mathematics achievement, and reading achievement, thus suggesting that aspects of physical fitness may be globally related to academic performance in preadolescents. The findings are discussed with regards to maximizing school performance and the implications for educational policies. 相似文献

Construct validity evidence for single-response items to estimate physical activity levels in large sample studies 总被引:1,自引:0,他引:1

Valid measurement of physical activity is important for studying the risks for morbidity and mortality. The purpose of this study was to examine evidence of construct validity of two similar single-response items assessing physical activity via self-report. Both items are based on the stages of change model. The sample was 687 participants (men = 504, women = 183) who completed an 8-response (PA8) or 5-response (PA5) single-response item about current level of physical activity. Responses were categorized as meeting or not meeting guidelines for sufficient physical activity to achieve a health benefit. Maximal cardiorespiratory fitness (CRF) and health markers were obtained during a clinical examination. Partial correlation, multivariate analysis of covariance, and logistic regression were used to identify the relations between self-reported physical activity, CRF, and health markers when controlling for gender and age. Single-response items were compared to a detailed measure of physical activity. Single-response items correlated significantly with CRF determined with a maximal exercise test on a treadmill (PA8 = .53; PA5 = .57). Differences in percentage of body fat and cholesterol were in the desired direction, with those self-reporting sufficient physical activity for a health benefit having the lower values. The single-response items demonstrated evidence of construct validity and may provide feasible, cost-effective, and efficient methods to assess physical activity in large-scale studies. 相似文献

This paper explores the nature of climate change education-related policy influence in England at a time when public consciousness about the need to accelerate climate change action was heightened, and as the 2018 climate strikes gathered momentum around the world. Informed by Foucault's concept of ‘governmentalities’, and using data generated through 24 exploratory interviews and reflexive thematic analysis, we examine the extent to which influential individuals were advocating for policy change. We discuss the nature of policy influence with particular reference to the ‘stances’ that individuals adopted relative to climate change education policy influence and noting a common tendency exhibited amongst participants which was a tendency towards ‘deference’. Coupling our insights with theorisations of dissent, we consider how ‘infra-political dissent’ could support key individuals to ‘step up’ and influence for more effective policy relative to climate change education, and to other areas of education or environment policy. 相似文献

This meta-analysis synthesizes research on media use in early childhood (0–6 years), word-learning, and vocabulary size. Multi-level analyses included 266 effect sizes from 63 studies (Ntotal = 11,413) published between 1988–2022. Among samples with information about race/ethnicity (51%) and sex/gender (73%), most were majority White/Non-Hispanic and between 40%–60% female. Analyses revealed a small overall positive relation between screen media exposure and vocabulary (r = .23). Experimental studies yielded a small-to-medium effect (r = .30), with stronger effects for e-books than TV/video or games/apps, and non-significant effects for video chat. In correlational studies, there was no overall association between vocabulary size and naturalistic media exposure (r = .07), with the exception of naturalistic exposure to educational media (r = .17). 相似文献
