Compared to competitive runners, recreational runners appear to be more prone to injuries, which have been associated with foot strike patterns. Surprisingly, only few studies had examined the foot strike patterns outside laboratories. Therefore, this study compared the foot strike patterns in recreational runners at outdoor tracks with previously reported data. We also investigated the relationship between foot strike pattern, speed, and footwear in this cohort. Among 434 recreational runners analysed, 89.6% of them landed with rearfoot strike (RFS). Only 6.9 and 3.5% landed with midfoot and forefoot, respectively. A significant shift towards non-RFS was observed in our cohort, when compared with previously reported data. When speed increased by 1 m/s, the odds of having forefoot strike and midfoot strike relative to RFS increased by 2.3 times and 2.6 times, respectively. Runners were 9.2 times more likely to run with a forefoot strike in minimalists compared to regular running shoes, although 70% of runners in minimalists continued to use a RFS. These findings suggest that foot strike pattern may differ across running conditions and runners should consider these factors in order to mitigate potential injury.  相似文献

Disruptive silence: deepening experiential learning in the absence of technology     

Carol A. Smith  Rodney Parks  Jesse Parrish  Ryan Swirski 《Journal of Adventure Education & Outdoor Learning》2018,18(1):1-14

Technology plays an integral role in the lives of the majority of the US population. As technology becomes integrated into young people’s lives, questions arise regarding its effects on learning. This exploratory study draws on interviews with students who attend university in the United States to determine how separating students from technology deepens experiential learning. Participants were interviewed following a study abroad course to New Zealand, during which they were disconnected from technologies such as cell phones, the Internet and social media. In the interviews, students discussed their feelings of being disconnected and describe how disconnecting impacted their overall experience. Participants agreed that disconnecting from technology had positive effects on experiential learning and the global experience. Major themes that emerged include students’ enhanced immersion and engagement, the value of disconnection in providing opportunities for personal growth and the difficulty of initial separation from technology as a result of conditioning.  相似文献   

Steps to abstract reasoning: An interdisciplinary program for cognitive development     

Dr. C. Rodney Killian  Dr. Catherine M. Warrick 《Innovative Higher Education》1980,4(3):189-200

A learning cycle approach to undergraduate instruction was implemented in a variety of subjects in the liberal arts and sciences. The students in the experimental program were typical representatives of an institution with liberal admissions policies. Significant gains were made in critical thinking and cognitive skill development by the experimental group. Additionally, retention of the experimental group was improved. Gains of this sort have the potential to rekindle hope in college faculties that some of the traditional goals of higher education that center on critical thinking and cognitive skill development need not be abandoned in institutions with liberal admissions policies.  相似文献   

A LONGITUDINAL STUDY OF THE DEVELOPMENT OF MATHEMATICS STRATEGIES AND UNDERLYING COUNTING SCHEMES     

Barry Biddlecomb  Martha Carr 《International Journal of Science and Mathematics Education》2011,9(1):1-24

The purpose of this study was to determine whether patterns of strategy use in second, third and fourth grade children’s arithmetic supported Steffe’s model of numerical development. In addition to student-generated strategies, we looked at commonly taught algorithms not considered in Steffe’s model to determine whether these algorithms reflected underlying schemes. 206 children were assessed on their strategy use while solving arithmetic problems in the second grade, the third grade and again in the fourth grade. Factor analyses indicated some support for Steffe’s model, but there were exceptions. Not all children progressed in their number knowledge and strategies as a function of schooling and schooling appeared to affect the types of strategies children use independent of underlying schemes.  相似文献

Cognitive Development in Gifted Children: Toward a More Precise Understanding of Emerging Differences in Intelligence   总被引：3，自引：0，他引：3  

Hillary Hettinger Steiner  Martha Carr 《Educational Psychology Review》2003,15(3):215-246

To truly understand gifted performance, it is necessary to merge research on giftedness with current thinking in cognitive development and intelligence. This article presents traditional research on gifted children's cognitive development then considers how the application of newer models and theories from the field of cognitive development can be combined with research on giftedness to change the way people think about gifted performance. First four factors that have often been associated with giftedness are discussed from the perspectives of cognitive developmental psychology and gifted education. Next, emphasis is placed on investigating the strategic development of gifted children. Specifically, R. S. Siegler's (Emerging Minds: The Process of Change in Children's Thinking, Oxford University Press, New York, 1996) model of strategy development is addressed in terms of what it may contribute to understanding gifted cognition. Finally, future lines of research using models from cognitive development and complex systems models of development are recommended.  相似文献

10 School decentralization and empowerment     

Rodney J. Reed 《教育政策杂志》2013,28(5):149-165

School results for children of poverty ‐ those forced by that poverty to live in inner‐city neighbourhoods ‐generally indicate educational failure at a much higher rate than is seen for students nurtured by wealthier school districts. This failure in school severely limits chances of social and economic upward mobility, which translates into a waste of human capital for the nation's business‐industrial‐political complex, and dashed hopes, dreams and self‐esteem for the individual. Parents and concerned citizens from across socio‐economic strata, long aware of the general inadequacy of schools in poor communities, have demanded improvement, often seeking it through legal and political means. Important strategies among the various federal, state and local school reform efforts to make schooling a meaningful process for all students, and particularly the minority poor, are decentralization and citizen/parent empowerment, the focus of this chapter. The movement to decentralize school governance ‐ an effort to place control into the hands of the people being served ‐ has gained momentum and exists in some form in most large‐city school districts today. An extension of administrative decentralization, citizen/parent empowerment is seen as one of several factors, including teacher and administrator preparation, curriculum renewal, school financing, and school restructuring, vital in the improvement of schools. A look at the meaning and scope of decentralization, operationalized through citizen/parent empowerment, and its probable effectiveness in improving school outcomes indicates that, alone, it is insufficient to ensure positive academic and social performance in school.  相似文献
