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

There are 5,020 scientific, technical and medical (STM) periodicals, including 548 English‐language (E‐L) journals, in China. To quickly increase the international influence of Chinese journals, government management launched significant initiatives for publishers, such as the ‘Project for Enhancing International Impact of China STM Journals (PIIJ, 2013–2018)’. This paper investigates the underlying objectives and assumptions made about the value and impact of Chinese E‐L journals and the effect of PIIJ support and international publisher collaboration. The authors conclude that, while the E‐L journals are demonstrating some quantifiable improvements in internationalization, there are no equal pressures or recognition for qualitative quality measures, and this may undermine the ability of Chinese E‐L journals to build sustainable strategic plans. 相似文献

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

The purpose of this study is to explore the factors that prompt askers to switch from free to paid social question-and-answer (SQA) services. Prior studies have investigated users’ motivations and participation in free and paid SQA services; however, little attention has been paid to askers’ switching behavior. We empirically analyzed the content of qualitative interviews from 64 askers on a well-known SQA platform in China. Based on the push-pull-mooring framework, we identified and classified factors that influenced askers’ to switch from free to paid Q&A services, using the critical incident technique, after which we calculated the entropy weights of the 16 subcategories before and after the switch, using the entropy weight method. The findings suggest that askers’ switching behavior was influenced by push factors (i.e., dissatisfaction with the free SQA service), pull factors (i.e., satisfaction with the paid SQA service), and mooring factors (i.e., social factors, personal factors, situational factors). Moreover, the findings show that the effects of these factors vary significantly before and after a switch. Dissatisfaction with the quality of information from the free SQA service would influence users before a switch, whereas satisfaction with the quality of information from the paid SQA service would influence them after a switch. In terms of mooring factors, the effects of social and personal factors on askers’ switching behavior, especially subjective norms and cognitive lock-in, turn out to be less significant after a switch, whereas the effect of trust is more significant. Besides, the effects of situational factors are more or less the same before and after a switch. To the best of our knowledge, this paper is one of the first attempts to explore factors that affect askers’ switching behavior and to shed light on the managerial strategies of paid SQA services. 相似文献
