Using an interactive platform to recognize the intersection of social and spatial inequalities     

Lisa Poling  Travis Weiland 《Teaching Statistics》2020,42(3):108-116

With the creation of interactive tasks that allow students to explore spatial ways of knowing in conjunction with their other ways of knowing the world, we create a space where students can make sense of information as they organize these new ideas into their already existing schema. Through the use of a Common Online Data Analysis Platform (CODAP) and data from Public Use Microdata Areas (PUMA), students can explore the communities in which they live and work, critically examining opportunities and challenges within a defined space.  相似文献

Closing the gap: supporting literacy through a computer-assisted-reading-intervention     

Kerry Vincent 《Support for Learning》2020,35(1):68-82

Schools in England are expected to ‘close the gap’ for a range of vulnerable pupils who are achieving below the levels seen amongst their same-aged peers. They are also highly accountable for additional funding that is provided to support this goal. The project reported here involved collating and analysing a range of data in order to evaluate the impact of a widely used computer-assisted-reading-intervention (CARI). Sixteen primary school pupils, all of whom were identified by their school as underachieving in literacy, used the CARI daily over a five-week period. The post-intervention data showed some clear gains in reading and spelling skills for all bar one of the children. The findings are discussed in relation to the wider literatures on CARIs. The research concludes that the CARI under investigation offers a useful and cost-effective adjunct to whole-class and group reading instruction and may be particularly beneficial for supporting the learning of pupils who are struggling to consolidate the knowledge and skills covered in their regular classroom reading instruction.  相似文献   

北美户外运动营地建设与经营管理模式研究     

张〓璐 《广州体育学院学报》2019,(4):54-56

新媒体时代打破了体育传统媒体的话语权垄断，迎来了“个人赋权”的体育媒体话语权格局。体育媒体话语平台多元化；体育媒体话语权的弥散化；体育媒体话语权的平民化是当前体育媒体话语权的态势。传统体育媒体也应积极面对新格局，化解危机。为此，拓宽话语平台，跨媒介融合；提升话语质量；整合话语体系是重塑传统体育媒体话语权的有效路径。  相似文献

共享模式下的集装箱空箱调运优化     

孙家庆  刘明丽  徐林坤  赵媛 《上海海事大学学报》2019,40(3):14-20

为解决共享模式下的集装箱空箱调运问题,基于航线、船舶运力、运输时间等限制性因素,以多决策期的空箱调运总成本最低为目标,建立集装箱共享系统的不确定需求随机机会约束模型。使用MATLAB,利用模拟退火(simulated annealing, SA)算法与遗传算法(genetic algorithm,GA)结合的混合算法进行数值求解和算例分析,表明模型是有效的,对船公司制订空箱共享、舱位共用策略有参考价值。  相似文献   

坦桑尼亚县域与城乡交通通达水平空间格局特征     

张家旗  陈爽  高群  ISMAEL A. Kimirei 《中国科学院大学学报》2019,36(6):766-773

坦桑尼亚是"一带一路"倡议通向非洲、辐射非洲内陆的重要门户，它在快速城市化过程中面临交通基础设施严重短缺问题。基于坦桑尼亚公路、铁路、机场、港口、人口和城市分布数据，运用GIS空间分析技术，结合交通通达指数模型，从县域与城乡两个层面对坦桑尼亚交通通达水平的空间格局特征进行定量分析。研究发现：1）坦桑尼亚县域交通通达水平空间分布极不均衡，高值连片区主要位于东北沿海和维多利亚湖沿岸，低值连片区主要位于中央铁路线中段以北、中央铁路线南部的广大地区；2）受地理区位、资源禀赋、殖民历史、政府政策等影响，城市与乡村地区之间的交通通达水平差异十分显著。研究结果有助于坦桑尼亚制定区域交通发展政策和优化资源配置，同时对中-坦产业精准对接和产能转移具有一定的促进意义。  相似文献   

Validity and reliability of a linear positional transducer across commonly practised resistance training exercises     

Harry F. Dorrell  Joseph M. Moore  Mark F. Smith  Thomas I. Gee 《Journal of sports sciences》2019,37(1):67-73

This study investigated the validity and reliability of the GymAware PowerTool (GPT). Thirteen resistance trained participants completed three visits, consisting of three repetitions of free-weight back squat, bench press, deadlift (80% one repetition maximum), and countermovement jump. Bar displacement, peak and mean velocity, peak and mean force, and jump height were calculated using the GPT, a three-dimensional motion capture system (Motion Analysis Corporation; 150 Hz), and a force plate (Kistler; 1500 Hz). Least products regression were used to compare agreeability between devices. A within-trial one-way ANOVA, typical error (TE; %), and smallest worthwhile change (SWC) were used to assess reliability. Regression analysis resulted in R² values of >0.85 for all variables excluding deadlift mean velocity (R² = 0.54–0.69). Significant differences were observed between visits 3-2 for bench press bar displacement (0.395 ± 0.055 m; 0.383 ± 0.053 m), and deadlift bar displacement (0.557 ± 0.034 m; 0.568 ± 0.034 m). No other significant differences were found. Low to moderate TE (0.6–8.8%) were found for all variables, with SWC ranging 1.7–7.4%. The data provides evidence that the GPT can be used to measure kinetic and kinematic outputs, however, care should be taken when monitoring deadlift performance.  相似文献   

‘Teaching’ the path towards university: understanding student access through storied-futures and meritocratic grand narratives     

Neil Anthony Buddel 《British Journal of Sociology of Education》2018,39(1):16-31

The notion that the stories of our lives shape dispositions towards imagined futures is another lens through which university underrepresentation should be viewed. A storied lens attends to how futures, like university attendance, are storied during childhood to the extent that some youth imagine, and therefore plan, these futures as natural progression. Such was the case for study participants, indicating that childhood stories contain answers for mitigating social reproduction connected to parental education and cultural forces within the home. Examining social mobility through the underexplored storied-futures grand narrative presents unique solutions that lay hidden within the dominant meritocratic grand narrative.  相似文献
