Learning through South–South development: Cuban-African partnerships in sport and physical education     

Simon C. Darnell  Robert Huish 《Compare》2017,47(2):286-299

Since the 1990s, Cuba has offered scholarships to students from low-resource countries to attend the Escuela Internacional de Educación Física y Deporte (EIEFD) for a six-year degree in sport, physical education, and coaching. Drawing on the experiences of EIEFD graduates from four Southern African countries (Zambia, South Africa, Mozambique, and Lesotho) the authors discuss the meanings that this South–South cooperation through education holds for international students and for the self-sufficiency of sport and physical-education systems within partner countries. The authors also show that upon returning home, many EIEFD graduates are left to negotiate insular job markets and inconsistent domestic commitments to public sport and physical education. The implications for South–South development through international education, and the place of sport and physical education therein, are discussed.  相似文献   

Integration and Physical Education: A Review of Research     

Risto Harri Juhani Marttinen  Gabriella McLoughlin  Ray Fredrick III  Dario Novak 《Quest (Human Kinetics)》2017,69(1):37-49

The Common Core State Standards Initiative has placed an increased focus on mathematics and English language arts. A relationship between physical activity and academic achievement is evident, but research on integration of academic subjects with physical education is still unclear. This literature review examined databases for the years 2004–2013, focusing on physical education or physical activity and core academic subjects for school-aged youth. 23 studies were found that focused on integration and physical education that met the inclusion criteria. These were from 16 different publication outlets, ranging in research methods, country, and population. This review provides information on the status of integration and physical education. Since classroom teachers are increasingly being encouraged to incorporate core subjects with physical activity into their classes, it would be appropriate for physical educators to understand the desired outcomes of integration of core subjects before attempting its implementation.  相似文献

Examining Chi-Square Test Statistics Under Conditions of Large Model Size and Ordinal Data     

Dexin Shi  Christine DiStefano  Heather L. McDaniel  Zhehan Jiang 《Structural equation modeling》2018,25(6):924-945

This study examined the effect of model size on the chi-square test statistics obtained from ordinal factor analysis models. The performance of six robust chi-square test statistics were compared across various conditions, including number of observed variables (p), number of factors, sample size, model (mis)specification, number of categories, and threshold distribution. Results showed that the unweighted least squares (ULS) robust chi-square statistics generally outperform the diagonally weighted least squares (DWLS) robust chi-square statistics. The ULSM estimator performed the best overall. However, when fitting ordinal factor analysis models with a large number of observed variables and small sample size, the ULSM-based chi-square tests may yield empirical variances that are noticeably larger than the theoretical values and inflated Type I error rates. On the other hand, when the number of observed variables is very large, the mean- and variance-corrected chi-square test statistics (e.g., based on ULSMV and WLSMV) could produce empirical variances conspicuously smaller than the theoretical values and Type I error rates lower than the nominal level, and demonstrate lower power rates to reject misspecified models. Recommendations for applied researchers and future empirical studies involving large models are provided.  相似文献

Addressing Physical Education Teacher Socialization Through Standards-based Reform of Physical Education Teacher Education     

K. Andrew R. Richards  Lynn D. Housner  Thomas J. Templin 《Quest (Human Kinetics)》2018,70(3):334-353

Research suggests that progress in the physical education profession is slowed by a cycle of nonteaching and dominance of traditional methodologies. Socialization factors operate to preserve and perpetuate the status quo of the profession, which is rooted primarily in team sport content. Teacher education programs are challenged to persuade pre-service teachers to question their initial belief structures while also preparing them for the sociopolitical realities of schools. There is not, however, a formal mechanism through which to accomplish these goals, because current accreditation standards do not include an emphasis on socialization. As a result, the purpose of this article is to stimulate further discussion by reviewing relevant research related to socialization, describe evidence-based practices for overcoming these challenges, and propose an addition to the Society of Health and Physical Educators America (2017) standards for initial physical education teacher education to specifically focus attention on socialization issues.  相似文献   

浅析学校体育与终生体育之有机结合
