Multi-age-grouping paradigm for young swimmers

The purpose of this study was to examine the adequacy of "multi-age" classification systems in youth sports with a specific focus on the unisex multi-age-groupings used by USA Swimming. In addition, we offer an analytical rationale for the multi-age-groupings and potential alternatives. We examined the top 100 US swim performances for three years (2005, 2006, and 2007) for girls and boys in 15 age-groups (7 to 20 years and a singular group of 21 years and older). Data for each age and sex were pooled over the three years and means were calculated for each of seven competitive swim events. Swim times differed among each age up to the 14-year age-group in girls (F (14,30885) = 183.9, P < 0.01, Cohen's d = 1.19-3.72, large effect) and 16-year age-group in boys (F (14,30885) = 308.7, P < 0.01, Cohen's d = 0.81-3.64, large effect) for all events. Age-related differences in swim times continued later in boys than girls likely due to differences between the sexes in timing of growth and maturation. Because of the differences in swim performance in contemporary multi-age-groups, stratifying swimmers by a single age is the best means to ensure competitive fairness and equality, although there is no rationale for swimmers under the age of 8 years to compete in separate unisex competitive groups.     

Can High School Achievement Tests Serve to Select College Students?

Postsecondary schools have traditionally relied on admissions tests such as the SAT and ACT to select students. With high school achievement assessments in place in many states, it is important to ascertain whether scores from those exams can either supplement or supplant conventional admissions tests. In this study we examined whether the Arizona Instrument to Measure Standards (AIMS) high school tests could serve as a useful predictor of college performance. Stepwise regression analyses with a predetermined order of variable entry revealed that AIMS generally did not account for additional performance variation when added to high school grade-point average (HSGPA) and SAT. However, in a cohort of students that took the test for graduation purposes, AIMS did account for about the same proportion of variance as SAT when added to a model that included HSGPA. The predictive value of both SAT and AIMS was generally the same for Caucasian, Hispanic, and Asian American students. The ramifications of universities using high school achievement exams as predictors of college success, in addition to or in lieu of traditional measures, are discussed.     

Longer-term effects of minimalist shoes on running performance,strength and bone density: A 20-week follow-up study*

This study investigated whether male runners improve running performance, running economy, ankle plantar flexor strength, and alter running biomechanics and lower limb bone mineral density when gradually transitioning to using minimalist shoes for 100% of weekly running. The study was a planned follow-up of runners (n?=?50) who transitioned to minimalist or conventional shoes for 35% of weekly structured training in a previous 6-week randomised controlled trial. In that trial, running performance and economy improved more with minimalist shoes than conventional shoes. Runners in each group were instructed to continue running in their allocated shoe during their own preferred training programme for a further 20 weeks while increasing allocated shoe use to 100% of weekly training. At the 20-week follow-up, minimalist shoes did not affect performance (effect size: 0.19; p?=?0.218), running economy (effect size: ≤?0.24; p?≥?0.388), stride rate or length (effect size: ≤?0.12; p?≥?0.550), foot strike (effect size: ≤?0.25; p?≥?0.366), or bone mineral density (effect size: ≤?0.40; p?≥?0.319). Minimalist shoes increased plantar flexor strength more than conventional shoes when runners trained with greater mean weekly training distances (shoe*distance interaction: p?=?0.036). After greater improvements with minimalist shoes during the initial six weeks of a structured training programme, increasing minimalist shoe use from 35% to 100% over 20 weeks, when runners use their own preferred training programme, did not further improve performance, running economy or alter running biomechanics and lower limb bone mineral density. Minimalist shoes improved plantar flexor strength more than conventional shoes in runners with greater weekly training distances.     

Effects of a minimalist shoe on running economy and 5-km running performance

The purpose of this study was to determine if minimalist shoes improve time trial performance of trained distance runners and if changes in running economy, shoe mass, stride length, stride rate and footfall pattern were related to any difference in performance. Twenty-six trained runners performed three 6-min sub-maximal treadmill runs at 11, 13 and 15 km·h^?1 in minimalist and conventional shoes while running economy, stride length, stride rate and footfall pattern were assessed. They then performed a 5-km time trial. In the minimalist shoe, runners completed the trial in less time (effect size 0.20 ± 0.12), were more economical during sub-maximal running (effect size 0.33 ± 0.14) and decreased stride length (effect size 0.22 ± 0.10) and increased stride rate (effect size 0.22 ± 0.11). All but one runner ran with a rearfoot footfall in the minimalist shoe. Improvements in time trial performance were associated with improvements in running economy at 15 km·h^?1 (r = 0.58), with 79% of the improved economy accounted for by reduced shoe mass (P < 0.05). The results suggest that running in minimalist shoes improves running economy and 5-km running performance.     

Higher education recruitment in the United States: a chronology of significant literature

ABSTRACT

Given the absence of a chronology of the historical philosophies, perspectives, and practices of recruitment within the higher education institutions in the United States, the authors have assembled an overview of the material on recruitment strategies and ideologies of American higher education institutions. Literature from and about the past aids in illuminating the current context while helping to navigate the future of higher education recruitment. The authors have identified five general periods: prior to 1920, 1921 to the end of the Second World War, the post-War decade, mid-1950s through the 1970s, and 1980s to the present. Documentation for each period varies significantly in quality and amount, with the densest data found for the two later periods. Future researchers may explore how recruitment practices and language encourage or discourage under-represented populations in higher education. Further research in other areas of educational recruitment is also suggested.     

Secondary school initiative in creating advanced placement opportunities

The most important opportunity available to secondary school students to earn college credit for college-level work done in high school is the series of advanced placement tests provided by such organizations as the College Entrance Examination Board. This paper presents three models of initiatives that can be taken by secondary school educators to create exams in those areas for which advanced placement tests do not currently exist and better serve the needs of their students who could prepare for current exams: adapt existing exams as credit-earning proficiency exams; work with interested universities in creating new advanced placement programs; and reorganizing the existing advanced placement program offered in the high school.     

Beyond the global city: a comparative analysis of cosmopolitanism in middle-class educational strategies in Australia and Brazil

ABSTRACT

The global middle class (GMC) is a theoretical construct that seeks to globalise a set of attributes identified in studies of school choice in the global north, and to a lesser extent in developing nations in Asia. As theorised by Ball a mobile middle class with cosmopolitan sensibilities drives international education options in global cities. This proposition is challenged through analysis of the histories of curriculum and class relations in two national settings (Australia and Brazil) and examination of contemporary class profiles (i.e. economic and cultural properties) in expanding forms of international education in these countries. The paper argues that the forms of cosmopolitanism associated with the educational practices of the GMC must be examined within broader historical relationships of cultural domination. We conclude by arguing that broadening the historical horizon is an important exercise to challenge the claim of the GMC to be a novel category involving exceptional forms of cultural contact generated by the dynamics of the ‘global city’.     

Supporting Personalized Learning through Individualized Learning Plans

Individualized Learning Plans (ILPs), an effective strategy to promote students’ college and career readiness, are increasingly used in US school systems as a mechanism to encourage students’ career exploration and identification of career goals. After describing features of ILPs, we provide an example of the ILP process developed and implemented in the junior high schools in McLean County (Illinois) Unit District No. 5. Based upon this experience, we share important factors for school leaders that can affect successful implementation in their schools.
