Health-related fitness knowledge growth in middle school years: Individual- and school-level correlates

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.     

研发团队知识协同动机研究——基于组织学习的视角

研究其内部知识协同的动机,对于企业更好的管理和激励团队成员积极参与知识协同具有十分重要的意义。本文基于组织学习的视角,从知识贡献者和知识寻求者两方面,探讨了影响研发团队成员主动参与知识协同的动机因素,并构建了理论模型。分析结果表明：个人声誉、共享意愿及群体认同对知识贡献者参与组织学习的动机具有不同影响;社会地位、渠道多样化及社会存在感对知识寻求者的主动性具有显著正向影响;应用性学习与探索性学习均对协同创新绩效有显著影响,且前者的影响大于后者;团队激励对组织学习和知识协同创新绩效间的关系具有干预调节作用。     

网上交谈对英语学习的激励作用初探

网络在教学中的普及促生了网上交谈在英语课堂的应用。本文通过实验数据对网络交谈和小组面谈的激励作用进行了比较分析,结果表明前者的激励作用较强,学生在网上交谈的分配和目标语的产出更为合理;学生也表示更喜欢网上交谈。因此,我们认为网上交谈可以作为英语教师组织课堂活动的一项有效补充。

Keep Fit and Play the Game

ABSTRACT

This article provides new insight into the modernization of the monarchy after the First World War by exploring how George VI promoted fitness and outdoor recreation during the interwar years. Sport functioned as a site of cross-class male bonding which formed part of a wider strategy by the monarchy to strengthen social cohesion. The new royal charities raised substantial funds, and they established a national fitness movement during the 1930s which was supported by the National Government, Labour leaders and the Trades Union Congress, but eschewed extremes on both left and right.     

Intercultural Communication Training for English Language Teachers: A Case Study of an Immersion Program for South Korean Teachers

Little research has been conducted that explores connections between the fields of intercultural communication and English-language instruction. To address this gap, we report on an intercultural communication course delivered as an integral part of a short-term professional development immersion program for English-language teachers from South Korea. Study results indicate that intercultural communication training served to enhance participants’ pragmatics awareness along with sensitivity regarding sociocultural influences on communication that they experienced in situ. After the four-week course, most of the participants expressed desire and readiness to integrate intercultural communication into their teaching in South Korea. Intercultural communication training promises to complement pragmatics instruction aiming at improving English-language learning and teaching.

也谈体育本质与体育教学问题——与《从体育本质看体育教学》作者商榷

对《从体育本质看体育教学》一文的相关论断提出质疑,指出该文的逻辑起点存在错误;论述自相矛盾;言语自我标榜;认识及说法上存在偏颇等,并就体育科学研究应遵循的态度及应承担的责任提出了看法。     

主场比赛的优势及其发挥

通过文献综述和逻辑分析,认为观众因素、熟悉因素是影响主场优势最重要的两个因素,这两个因素将影响着比赛的3个主要参与者即运动员、教练员和裁判员的临界心理状态和行为状态,从而最终影响着比赛的结果。同时认为运动员(队)要想获得更大的主场胜率,必须善于充分利用主场比赛的一切有利因素,并进行专门、针对性的准备,才能最终将主场优势变成主场胜势。
