The relationship between qualified personnel and self-reported implementation of recommended physical education practices and programs in U.S. schools     

Davis KS  Burgeson CR  Brener ND  McManus T  Wechsler H 《Research quarterly for exercise and sport》2005,76(2):202-211

The authors analyzed data from the School Health Policies and Programs Study 2000 to assess the associations between the presence of a district physical education coordinator and district-level physical education policies and practices recommended by federal government agencies and national organizations. The authors also examined the relationship between teacher qualifications and staff development related to physical education and self-reported implementation of recommended teachingpractices. District-level data were collected by self-administered mail questionnaires from a nationally representative sample of school districts. Classroom-level data were collected by computer-assisted personal interviews with teachers of randomly selected classes in elementary schools and randomly selected required physical education courses in middle/junior high and senior high schools. Nearly two thirds (62.2%) of districts had a physical education coordinator, and those were generally more likely than other districts to report having policies and practices that corresponded with national recommendations for high-quality physical education programs. More than two thirds of teachers (66.9%) met the criteria for teacher qualifications based on their education and certification. These teachers were more likely than others to report use of certain recommended physical education teaching practices. Teachers who participated in staff development also were more likely to use recommended teaching practices in their classrooms. Using a district physical education coordinator and teachers with appropriate qualifications as well as offering staff development opportunities on physical education may enhance school physical education programs.  相似文献   

A review of literacy frameworks for learning environments design     

Kristen Radsliff Rebmann 《Learning Environments Research》2013,16(2):239-257

This article charts the development of three literacy research frameworks: multiliteracies, new literacies, and popular literacies. By reviewing the literature surrounding three current conceptions of literacy, an attempt is made to form an integrative grouping that captures the most relevant elements of each for learning environments design. Rather than showcasing the merits and weaknesses of each perspective (resulting in theoretical ‘winners and losers’), the frameworks are used to derive a core set of principles which might inform the design of interventions and artifacts to promote learning within informal learning environments for youth. These principles include exploring lifeworlds, recognising sources of power, multimodality, intertextuality, play and popular culture, design and production, and changing roles for adults.  相似文献   

How different are they? A comparison of Generation 1.5 and international L2 learners’ writing ability     

Kristen di Gennaro 《Assessing Writing》2013,18(2):154-172

A growing body of literature in second-language writing suggests that the writing ability of international second language (L2) learners, who attend post-secondary education abroad after having completed high school in their home countries, and the so-called Generation 1.5 population, that is, L2 learners who enter post-secondary education after attending high school in the new country, differs. The present study provides much-needed empirical evidence concerning potential differences in the writing ability of these two groups. Many-facet Rasch measurement procedures were used to analyze learners’ writing scores in five components, based on a theoretical model of writing ability: grammatical, cohesive, rhetorical, sociopragmatic, and content control. Results revealed that the international learners performed better overall than the Generation 1.5 learners and that the two groups had opposing strengths and weaknesses in grammatical and sociopragmatic control. Language program administrators and practitioners can use these results when designing curricula addressing the needs of diverse groups of L2 learners.  相似文献   

A Socioecological View of Higher-Performing Diverse Elementary Schools     

Kristen Campbell Wilcox 《Journal of Education for Students Placed at Risk》2013,18(2):101-127

This multiple case study relied upon a socioecological framework and the lens of resilience to investigate practices and processes that are correlated with higher academic achievement among African American, Hispanic, and English language learners. Utilizing quantitative measures for sample selection of 10 higher-performing and 5 average-performing schools and qualitative data collection and analysis methods, findings indicate that 4 interrelated practices characterize higher-performing diverse schools: close engagement with and understanding of the student population; intensive literacy- and technology-enriched instruction; a collaborative and iterative approach to curriculum revision and data use; and fluid adaptation and deployment of resources. One of the 15 diverse high-poverty case study schools is discussed in detail as an exemplar. The findings from this study suggest that research cutting across levels of classrooms, schools, and districts sheds light on the interrelated proximal and distal processes that promote resilience and higher academic achievement among ethnically and linguistically diverse students.  相似文献   

Fluency Has a Role in the Simple View of Reading     

Rebecca D. Silverman  Deborah L. Speece  Jeffrey R. Harring  Kristen D. Ritchey 《Scientific Studies of Reading》2013,17(2):108-133

The Simple View of Reading (SVR) suggests that the components of reading comprehension are decoding and linguistic comprehension. Given research that suggests that fluency is a separate construct from decoding and linguistic comprehension in fourth grade, the aim of this study was to examine the role of fluency in the SVR model. Analyses of data from 248 fourth-grade children explored whether the influence of fluency on reading comprehension is direct or whether fluency plays an indirect role on reading comprehension as a mediator or moderator of decoding. Structural equation modeling and latent regression analyses revealed that reading fluency plays a mediating role in explaining the relation between decoding and reading comprehension. This novel finding is placed in the context of studies that reported either a direct effect or no effect of reading fluency in SVR.  相似文献

Power training in elite young soccer players: Effects of using loads above or below the optimum power zone     

Irineu Loturco  Lucas A. Pereira  Valter P. Reis  Chris Bishop  Vinicius Zanetti  Pedro E. Alcaraz 《Journal of sports sciences》2020,38(11-12):1416-1422

ABSTRACT

This study aimed to examine the effects of two jump squat (JS) training programs involving different loading ranges in under-20 soccer players during a preseason period. Twenty-three elite young soccer players performed sprint speed (at 5-, 10-, and 20-m), change-of-direction (COD) speed, JS peak-power (PP), and countermovement jump (CMJ) tests pre and post four weeks of training. Athletes were pair-matched in two groups according to their optimum power loads (OPL) as follows: lower than OPL (LOPL; athletes who trained at a load 20% lower than the OPL) and higher than OPL (HOPL; athletes who trained at a load 20% higher than the OPL). Magnitude-based inferences were used to compare pre- and post-training measures. Meaningful increases in the PP JS were observed for both groups. Likely and possible improvements were observed in the 5- and 10-m sprint velocity in the LOPL group. Meanwhile, possible and likely improvements were observed in the CMJ, 5- and 10-m sprint velocity, and COD speed in the HOPL group. Overall, both training schemes induced positive changes in athletic performance. Soccer coaches and sport scientists can implement the JS OPL-based training schemes presented here, either separately or combined, to improve the physical performance of youth soccer players.  相似文献   

Making Connections: Linking Cognitive Psychology and Intervention Research to Improve Comprehension of Struggling Readers     

Kristen L. McMaster  Christine A. Espin  Paul van den Broek 《Learning disabilities research & practice》2014,29(1):17-24

Many studies have demonstrated the efficacy of reading comprehension interventions for struggling readers, including students with learning disabilities. Yet, some readers continue to struggle with comprehension despite receiving these interventions. In this article, we argue that an explicit link between cognitive psychology and intervention research contributes to knowledge regarding for whom and under what conditions reading comprehension interventions are most likely to be beneficial. First, we provide a brief overview of a cognitive perspective on reading comprehension. Next, we illustrate an application of this perspective by describing a collaborative project in which we examined interactions among reader characteristics, text properties, and instructional contexts. Last, we highlight directions for future research and implications for practice.  相似文献   

The effect of exercise interventions on resting metabolic rate: A systematic review and meta-analysis     

Kristen MacKenzie-Shalders  Jaimon T. Kelly  Daniel So  Vernon G. Coffey  Nuala M. Byrne 《Journal of sports sciences》2020,38(14):1635-1649

ABSTRACT

The systematic review and meta-analysis evaluated the effect of aerobic, resistance and combined exercise on RMR (kCal·day^-1) and performed a methodological assessment of indirect calorimetry protocols within the included studies. Subgroup analyses included energy/diet restriction and body composition changes. Randomized control trials (RCTs), quasi – RCTs and cohort trials featuring a physical activity intervention of any form and duration excluding single exercise bouts were included. Participant exclusions included medical conditions impacting upon RMR, the elderly (≥65 years of age) or pregnant, lactating or post-menopausal women. The review was registered in the International Prospective Register of Systematic Reviews (CRD 42,017,058,503). 1669 articles were identified; 22 were included in the qualitative analysis and 18 were meta-analysed. Exercise interventions (aerobic and resistance exercise combined) did not increase resting metabolic rate (mean difference (MD): 74.6 kCal·day^-1[95% CI: ?13.01, 161.33], P = 0.10). While there was no effect of aerobic exercise on RMR (MD: 81.65 kCal·day^-1[95% CI: ?57.81, 221.10], P = 0.25), resistance exercise increased RMR compared to controls (MD: 96.17 kCal·day^-1[95% CI: 45.17, 147.16], P = 0.0002). This systematic review effectively synthesises the effect of exercise interventions on RMR in comparison to controls; despite heterogenous methodologies and high risk of bias within included studies.  相似文献
