BackgroundHealth-related fitness knowledge (HRFK) has been an essential concept for many health and physical education programs. There has been limited understanding and longitudinal investigation on HRFK growth. This longitudinal study examined HRFK growth and its individual- and school-level correlates in middle school years under 1 curriculum condition: Five for Life.MethodsParticipants were 12,044 students from 47 middle schools. Data were collected at both individual/participant and school/institution levels. Individual-level variables included gender, grade, and HRFK test scores. School-level variables included percentage of students receiving free and reduced meals (FARM), student-to-faculty ratio for physical education, and school academic performance (SAP). We used hierarchical linear modeling to examine HRFK 3-year growth in relation to individual- and school-level correlates.ResultsThe average HRFK score at 6th grade for females was 42.81% ± 1.32%. The predicted HRFK growth was 17.06% ± 1.02% per year, holding other factors constant. A 1-standard deviation increase in FARM correlated with a 14.68%-point decrease in predicted test score (p = 0.02). A 1-standard deviation increase in SAP was associated with an 11.90%-point increase in HRFK score. Males had a significantly lower growth rate than females during the middle school years (0.78%/year, p = 0.02).ConclusionThe result showed that both individual- and school-level variables such as gender, FARM, and SAP influenced HRFK growth. Educators should heed gender differences in growth curves and recognize the correlates of school-level variables.  相似文献

土司体育文化在永顺县中小学推广现状的调查与分析——以土家族摆手舞为例     

向依依  郑军 《体育科技文献通报》2020,(2):24-26

为促进土司体育文化更好的开展,扩展土家摆手舞的开展范围和提高摆手舞的质量,促进土司体育的发展,提高学生身体素质和文化修养。本文采用文献资料法、问卷调查法、座谈访问法、逻辑分析法,对永顺县中小学土家摆手舞开展的现状进行调查与分析。结果认为,永顺县中小学摆手舞存在学生学习兴趣不高、对摆手舞认知不足的现象,学校也因为资金受限,体育教学场地存在教学用面积不足及地面不平整状况,多数老师靠自学和其他老师所教学习的摆手舞,体育教师认为师资分配不合理现象存在,并且多数学生认为体育教师教学动作不够规范,直接影响了摆手舞在中小学的发展。  相似文献   

高校体育教学动态教学成效监测指标建设探究     

王放 《体育科技文献通报》2020,(5):36-37,40

在素质教育稳步推进和新教改不断深化的背景下,高校体育教学改革主动进行了各种尝试,但在教法改革方面依然不足,就目前高校人才培养成效看仍存在各种局限。因此,当前我国高校体育教育应注重教学方法的改革和探索,提升人才培养成效。笔者在进行长期的教学探索与反思基础上,创新性地提出了动态教学成效监测机制,并致力于动态教学成效监测指标建设,目的在于真正落实高校体育教学的宗旨和人才培养指标,实现学生体育素养、体质全面提升与体育文化素养并举的教学目的。  相似文献

网球精英运动员赛间训练调控影响因素SEM分析     

汤国进  邹克宁 《武汉体育学院学报》2020,54(9):86-94

为定量解释精英运动员重大比赛期间竞技状态显性和隐性影响因素间相互关系，运用文献资料、层次分析、模糊评价、数理统计等研究方法，基于国家队、省市运动队295名网球教练员、运动员调研数据，提出精英网球运动员重大比赛期间竞技状态影响因素假设命题，再引入SEM概念模型，对假设命题进行验证。结果表明：（1）竞技状态SEM概念模型中，体能训练整合度、技能训练整合度、心智训练整合度、适应度与保障度可作为隐性自变量，且均对竞技状态因变量有正向影响作用，H₁、H₂、H₃、H₄假设命题得到验证；（2）经SEM检验，依影响因素权重，精英网球运动员赛间竞技状态调控依次表现为技能训练整合度、心智训练整合度、体能训练整合度、适应度与保障度；（3）精英网球运动员的参赛表现，虽主要取决于竞技训练因子，但对于适应度与保障度中自然环境、社会环境和规程规则等非训练因子，同样不容忽视。  相似文献

Role of teacher-related factors and educational resources in science literacy: An international perspective     

《Studies in Educational Evaluation》2020

The study evaluated the relationship among teaching, leadership, teacher certification, student and teacher number related factors, and index of economic, social and cultural status (ESCS), and science literacy from an international comparative perspective. 2015 dataset of the Programme for International Student Assessment for Turkey, Singapore, the United States, Korea, Italy, and Brazil was used. Two-level hierarchical linear models were established for analysis. Results revealed that school ESCS was the best predictor of science literacy across six countries and additionally teacher-related factors came to the forefront of science literacy performance. The study underlined policymakers should focus primarily on policies that increase equity in education. Furthermore, the effectiveness of investments made in factors related to leadership, teacher certification, the number of students and teachers, which contribute very little to science literacy performance, need to be more questioned. Inferences about the findings were discussed in detail, and recommendations for further research were made.  相似文献   

Adverse experiences in infancy and toddlerhood: Relations to adaptive behavior and academic status in middle childhood     

《Child abuse & neglect》2018

Findings from the Adverse Childhood Experiences (ACE) study articulated the negative effects of childhood trauma on long-term well-being. The purpose of the current study is to examine the associations between ACEs experienced in infancy and toddlerhood and adaptive behavior and academic status in middle childhood. We used data collected from a sample of low-income families during the impacts study of Early Head Start (EHS). Data were collected by trained interviewers demonstrating at least 85% reliability with protocols. Data come from 1469 socio-demographically diverse mothers and children collected at or near ages 1, 2, 3, and 11. At ages 1, 2, and 3, an EHS-ACEs index was created based on interview and observation items. The EHS-ACEs indices were averaged to represent exposure across infancy and toddlerhood. At age 11, parents were asked about school outcomes and completed the Child Behavior Checklist. Across development, children were exposed to zero (19%), one (31%), two (27%), and three or more ACEs (23%). Logistic regression analyses, controlling for EHS program assignment, and parent, school, and child characteristics, showed ACEs were significantly associated with parental report of the child: having an individualized educational program since starting school and in the current school year, having been retained a grade in school, and problems with externalizing and internalizing behavior, as well as attention. Findings suggest that ACEs influence children’s behavioral and academic outcomes early in development.  相似文献
