写作智慧内涵及构成刍议

建构写作智慧体系是写作教学的出发点和归宿。建构写作智慧体系,需要整合五个方面的内容:传递写作知识、提升认识智慧、传导认知策略、培养写作技能、传授写作策略。

中国四省市与新加坡学生科学素养表现之比较——基于PISA2015数据的分析

PISA2015科学素养测试结果于2016年底正式公布后,受到社会各界的广泛关注。研究者从OECD在线公布的数据库中选取中国四省市与新加坡的有关数据,对两个经济体15岁在校生的科学素养表现进行比较分析,并通过多水平分析探讨影响学生科学素养的关键因素。结果发现:中国四省市学生在科学素养测试总量表及各分量表上的成绩均非常显著地低于新加坡学生,分差在32.82~43.29之间,效应量达到中等强度;中国四省市学生在工具性动机上得分非常显著地高于新加坡学生,但在科学乐趣与科学自我效能得分上非常显著地低于新加坡学生;在影响因素方面,家庭经济、社会和文化地位、科学乐趣、科学课纪律氛围、教师中科学教师的比例等因素对两个经济体的学生成绩具有显著正向预测效应,但考试焦虑、工具性动机、教师探究式教学等因素表现出显著的负向预测效应。中国四省市要有意识地借鉴新加坡教育经验,改革与完善科学教育,具体建议有:(1)进一步推动课程与教学改革,重视探究式教学与学生批判性思维的培养;(2)加强学校人力资源管理,提高教师专业水平;(3)关注学生非认知表现,激发学生科学学习的内部动机。     

浅析CET-4听力理解题与答题技巧

大学英语的教学目的是“使学生能以英语为工具,获取所需信息”。听车理解,即“听而理解意思”。在考试中要求考生边听、边理解、边阅读、边猜测（推断）,边作选择。本文通过对大学生英语CET－4听力理解题的分析谈一些答题技巧。     

利用引文确定领域关键文献的方法探析

[目的/意义]确定基于引用关系提取关键文献时各种方法的优缺点、适用场合,从而使用户快速捕捉领域重要文献,掌握领域概貌。[方法/过程]基于文献引用关系,从文献被引频次、文献引用网络、文献共被引网络3个角度,结合HistCite、CiteSpace等软件探讨领域关键文献的识别方法,通过同源数据的实际验证,对不同方法进行判别比较。[结果/结论]基于被引频次的方法更适合选择特定领域中哪些文献对总体文献的科学进步产生重大影响角度提取关键文献,对应的关键文献集合呈现非常分散的特性;基于引用网络的方法更适合从特定领域研究动态提取发展过程中的关键文献,对应的关键文献集合呈现非常明显的集中特性;基于共被引网络的方法更适合从特定领域研究基础角度提取关键文献,对应的关键文献集合呈现较强的集中性,且能发现原始采集中未发现的大量关键文献。     

英语阅读障碍的克服

在第二语言学习中，阅读英语阅读能力不高，主要原因是阅读时有很多障碍，克服这些障碍，是提高阅读阅读能力的关键。

Mediating effects of resistance training skill competency on health-related fitness and physical activity: the ATLAS cluster randomised controlled trial

The purpose of this study was to examine the mediating effect of resistance training skill competency on percentage of body fat, muscular fitness and physical activity among a sample of adolescent boys participating in a school-based obesity prevention intervention. Participants were 361 adolescent boys taking part in the Active Teen Leaders Avoiding Screen-time (ATLAS) cluster randomised controlled trial: a school-based program targeting the health behaviours of economically disadvantaged adolescent males considered “at-risk” of obesity. Body fat percentage (bioelectrical impedance), muscular fitness (hand grip dynamometry and push-ups), physical activity (accelerometry) and resistance training skill competency were assessed at baseline and post-intervention (i.e., 8 months). Three separate multi-level mediation models were analysed to investigate the potential mediating effects of resistance training skill competency on each of the study outcomes using a product-of-coefficients test. Analyses followed the intention-to-treat principle. The intervention had a significant impact on the resistance training skill competency of the boys, and improvements in skill competency significantly mediated the effect of the intervention on percentage of body fat and the combined muscular fitness score. No significant mediated effects were found for physical activity. Improving resistance training skill competency may be an effective strategy for achieving improvements in body composition and muscular fitness in adolescent boys.     

Dribbling determinants in sub-elite youth soccer players

Dribbling speed in soccer is considered critical to the outcome of the game and can assist in the talent identification process. However, little is known about the biomechanics of this skill. By means of a motion capture system, we aimed to quantitatively investigate the determinants of effective dribbling skill in a group of 10 Under-13 sub-elite players, divided by the median-split technique according to their dribbling test time (faster and slower groups). Foot-ball contacts cadence, centre of mass (CoM), ranges of motion (RoM), velocity and acceleration, as well as stride length, cadence and variability were computed. Hip and knee joint RoMs were also considered. Faster players, as compared to slower players, showed a 30% higher foot-ball cadence (3.0 ± 0.1 vs. 2.3 ± 0.2 contacts · s^?1, P < 0.01); reduced CoM mediolateral (0.91 ± 0.05 vs. 1.14 ± 0.16 m, P < 0.05) and vertical (0.19 ± 0.01 vs. 0.25 ± 0.03 m, P < 0.05) RoMs; higher right stride cadence (+20%, P < 0.05) with lower variability (P < 0.05); reduced hip and knee flexion RoMs (P < 0.05). In conclusion, faster players are able to run with the ball through a shorter path in a more economical way. To effectively develop dribbling skill, coaches are encouraged to design specific practices where high stride frequency and narrow run trajectories are required.
