对2000年以来国际乒联对乒乓球规则的改革进行梳理,分析乒乓球规则修改后的影响,并提出相应策略,旨在为中国乒乓球的更好发展提供参考。结果表明:20年以来,主要从器材、技术、赛制三个方面进行乒乓球规则改革,促进了乒乓球项目的竞争性和观赏性,世界乒坛格局呈多元化发展。面对新规则带来的变化,中国乒乓球队应正确把握制胜规律,对新规则加强针对性训练,对规则变化进行科学决策,积极创新技战术打法,依托科研保障团队,为科学训练提供支撑,从而保持中国队在世界乒坛的领先地位。  相似文献

Meta-analysis is the synthesis of findings from research projects, which enables an estimate of the average or pooled effect across various studies. This study presents findings from the intention to treat analysis for a series of educational evaluations in England using a two-stage meta-analysis with standardised outcome data and individual participant data meta-analyses. The research estimates the overall impact of educational trials on pupils eligible for Free School Meals (FSM) and the attainment gap in literacy and mathematics performance between FSM and non-FSM pupils based on analysis of 88 trials and data from over half a million pupils. For the meta-analyses, frequentist and Bayesian multilevel models were used to estimate the individual and pooled effect size across categories of explanatory variables such as age groups (key stages in England) and aspects of the type of interventions (one-to-one, small group, whole class). Results indicated that the overall impact of interventions on the literacy outcomes of FSM pupils was positive, with a pooled effect size of 0.06 (0.03, 0.08). However, for mathematics, no overall effect on FSM pupils was observed. Analysis of the attainment gap indicated that literacy outcomes for FSM pupils were improved by interventions marginally more than for non-FSM pupils (pooled attainment gap 0.01 (−0.01, 0.04)). The risk of bias assessment showed that estimates were consistent across different methodological approaches. Overall, evidence from this study can be used to identify, test and scale educational interventions in schools to improve educational outcomes for disadvantaged pupils.  相似文献

社会经济地位是影响个体身体活动参与的重要社会因素。通过对国内外相关研究文献进行分析,检验社会经济地位对不同群体身体活动的影响效应,梳理社会经济地位影响个体身体活动参与的作用路径,发现:(1)社会经济地位对个体的身体活动具有重要影响,但对青少年、普通人群和特殊人群身体活动的影响效应存在差异;(2)社会经济地位通过社区环境(体育活动设施、社区学校条件)、家庭因素(家庭物质环境、家庭成员身体活动行为)、久坐行为、超重或肥胖、锻炼动机(锻炼意图、自我效能)等因素对个体身体活动产生影响。(3)当前关于社会经济地位与身体活动关系的研究存在核心概念的界定与测量混乱、社会经济地位影响身体活动的理论构建缺乏等问题。  相似文献

We test acculturative stress, Hybrid (HIS) and Alternating (AIS) Identity Styles, and their interaction effects as predictors of psychosocial functioning over a 12-day period among Hispanic American university students. Participants completed measures of acculturative stress, HIS, AIS, and internalizing (anxiety and depression) and externalizing (social aggression and rule-breaking) symptoms on Day 1; on Day 12 they completed the symptom measures a second time. Structural equation modelling was used to examine the Day 1 effects of acculturative stress, cultural identity styles, and their interactions on Day 12 symptoms controlling for the Day 1 symptoms. We hypothesized that acculturative stress would predict more, and the HIS would predict fewer, symptoms and that the AIS would moderate the relationship between acculturative stress and symptoms over time. Results indicated that: (1) acculturative stress predicted an increase in internalizing symptoms; (2) the HIS predicted a decrease in internalizing and externalizing symptoms; and (3) the AIS attenuated the relationship between acculturative stress and externalizing symptoms. The results are discussed in relation to the distinctive features of internalizing and externalizing symptoms, and recommendations for future research are advanced.  相似文献

Abstract

Inclusive education is promoted as an educational setting that brings together students with disabilities alongside non-disabled peers. As the rise in inclusive education continues, many recognize the Salamanca Statement of 1994 as an influencer. This paper discusses how the vision of inclusion grounded in “the need to work towards ‘schools for all’” remains unfulfilled through a lack of intersectionality. Centering the experiences of Spanish-speaking mothers of emergent bilinguals labeled as disabled, this paper presents how educators limit parents’ abilities to engage as equal stakeholders. Therefore, this paper explores the tensions culturally and linguistically diverse mothers encounter during Individual Education Plan (IEP) meetings and the possibilities that can come from reimagining IEPs and IEP meetings in ways that allow stakeholders to actively tend to the intersectional vision of inclusive education that Salamanca put forth and that emergent bilinguals labeled as disabled desperately need.  相似文献

Individual vendors and their market booths constitute a collective atmosphere in the marketplace by getting together with spatial arrangements, operational collaborations and event‐based dynamics. The base of study is how these dynamic interactions in a marketplace can find a place within the education process and representations of the architectural design studio. The workshop which was organised in this context consists of personal representations (drawings are produced for each individual market booth and represent all movements and time‐varying conditions on market booths by superposed layers) and collectively produced narratives (which emerged by gathering personal representations together in the studio). In this study, collective and generative potentials of education in a design studio will be discussed thanks to the transfers from the marketplace.  相似文献

人工智能时代的不期而至将重塑教学的课堂形态。基于人工智能的课堂教学无论其教学手段、教学方式、教学内容、教学设计、教学过程乃至教学评价等都将以智慧性、泛在性和场景的融合性为表征,知识呈现的形式与场景的融合使教学的“现实场景”凸显,学生发展的“审美创造”成为可能。然而,人工智能时代的教育面临的挑战不容小觑,知识目的观的“祛魅”与人性目的观的“返魅”、单质主客体的“消减”与多元主体的“建构”、“授人以渔”的方法论转向“授人以欲”主体论、学习的“苦行僧”变为意义生成的“审美者”,等等。基于此,就其改进策略而言,教学中“人是目的”的根本要素依然需要持守并要不断弘扬,无论环节、情景、方式、模式等发生何等变换,都是为人的全面发展而服务的。因此,遵循“立德树人”的根本宗旨,以知识“塑造灵魂”;培养混合式、人机融合式的教学模式创构能力;创造“人际”“人机”与“人世”精神交往的教学关系;以劳动教育为基础,以审美教育为灵魂,“五育并举”,创造丰富多样的综合实践活动形式,共同形成一个相互联系的有机整体,培养德智体美劳全面发展的社会主义事业的建设者和接班人。  相似文献

在社会不确定性事件下,经典经济学的完全理性受到了来自认知科学的挑战。认知经济学的发展冲破了完全理性的局限,提出在社会不确定事件下,存在着个体的有限理性和群体的有限理性,强调要正确认识个体理性和学习、群体理性和制度演化的关系。认知经济学在本体论上属于个人主义,在认识论上属于实证主义,与经典经济学处于完全不同的路径。  相似文献
