小学道德与法治课程校本化实施的基本路径     

胡莉英  高德胜 《上海教育科研》2020,(1):57-60

道德与法治课程要落实立德树人的根本任务,发挥"道德情感启蒙"的教育作用,在拥有《课程标准》、系列文件和"文化母乳"般教材基础上,只有引导学校、教师找到校本化实施的基本路径,才能真正发挥其在课程体系中的政治引领和价值引领作用。这个路径就是以把握课标、吃透教材为基础,以基于学情、深化目标为灵魂,以"新鲜"事件为拓展资源,以便于操作的教学模式为关键,以提升品位、知行合一为策略。  相似文献   

Increased foot-stretcher height improves rowing performance: evidence from biomechanical perspectives on water     

Yang Liu  Binghong Gao  Jiru Li  Zuchang Ma  Yining Sun 《Sports biomechanics / International Society of Biomechanics in Sports》2020,19(2):168-179

Abstract

The aim of this study was to investigate whether changes on foot-stretcher height were associated with characteristics of better rowing performance. Ten male rowers performed a 200 m rowing trial at their racing rate at each of three foot-stretcher heights. A single scull was equipped with an accelerometer to collect boat acceleration, an impeller with embedded magnets to collect boat speed, specially designed gate sensors to collect gate force and angle, and a compact string potentiometer to collect leg drive length. All sensor signals were sampled at 50 Hz. A one-way repeated measures ANOVA showed that raising foot-stretcher position had a significant reduction on total gate angle and leg drive length. However, a raised foot-stretcher position had a deeper negative peak of boat acceleration at the catch, a lower boat fluctuation, a faster leg drive speed, a larger gate force for the port and starboard side separately. This could be attributed to the optimisation of the magnitude and direction of the foot force with a raised foot-stretcher position. Although there was a significant negative influence of a raised foot-stretcher position on two kinematic variables, biomechanical evidence suggested that a raised foot-stretcher position could contribute to the improvement of rowing performance.  相似文献   

Application of network meta-analysis in the field of physical activity and health promotion

Continued advancement in the field of physical activity and health promotion relies heavily on the synthesis of rigorous scientific evidence. As such, systematic reviews and meta-analyses of randomized controlled trials have led to a better understanding of which intervention strategies are superior (i.e., produce the greatest effects) in physical activity-based health behavior change interventions. Indeed, standard meta-analytic approaches have allowed researchers in the field to synthesize relevant experimental evidence using pairwise procedures that produce reliable estimates of the homogeneity, magnitude, and potential biases in the observed effects. However, pairwise meta-analytic procedures are only capable to discerning differences in effects between a select intervention strategy and a select comparison or control condition. In order to maximize the impact of physical activity interventions on health-related outcomes, it is necessary to establish evidence concerning the comparative efficacy of all relevant physical activity intervention strategies. The development of network meta-analysis (NMA)—most commonly used in medical-based clinical trials—has allowed for the quantification of indirect comparisons, even in the absence of direct, head-to-head trials. Thus, it stands to reason that NMA can be applied in physical activity and health promotion research to identify the best intervention strategies. Given that this analysis technique is novel and largely unexplored in the field of physical activity and health promotion, care must be taken in its application to ensure reliable estimates and discernment of the effect sizes among interventions. Therefore, the purpose of this review is to comment on the potential application and importance of NMA in the field of physical activity and health promotion, describe how to properly and effectively apply this technique, and suggest important considerations for its appropriate application in this field. In this paper, overviews of the foundations of NMA and commonly used approaches for conducting NMA are provided, followed by assumptions related to NMA, opportunities and challenges in NMA, and a step-by-step example of developing and conducting an NMA.  相似文献   

液滴撞击凹凸槽道表面液膜的动态演变     

周鑫  王宏  朱恂  陈蓉  廖强  丁玉栋 《中国科学院大学学报》2020,37(2):255-262

为研究固体表面结构对液滴撞击液膜后演变行为的影响规律，采用CLSVOF方法模拟液滴撞击不同尺寸槽道上的表面液膜的流动过程，获得不同槽道高度和宽度时液滴撞击液膜后的演变行为，探索撞击速度、液膜黏度和表面张力对撞击后液膜铺展行为、水花飞溅高度和二次液滴形成的影响。结果表明，槽道结构对液滴撞击液膜后的动态行为具有显著影响，随着槽道高度的增加，冠状水花厚度越薄，越容易产生二次液滴；随着液膜黏度的增大，则抑制冠状水花形成与二次液滴的产生；液膜表面张力减小时，射流更加明显，二次液滴数更多，飞溅现象提前，冠状水花消失时间延后。  相似文献
