The effect of number of siblings and birth order on educational attainment: Empirical Evidence from Chinese General Social Survey     

《International Journal of Educational Development》2020

Data from China demonstrate that the effect of the number of siblings on education is restricted by many factors, such as children’s gender, urban or rural household registration, whether there is only one child, the birth order of children within the family, and parents’ status. Chinese families have significant preferences for the eldest son and the youngest son. Moreover, research based on the natural experiment and instrumental variable approach suggests that market-oriented reform of education has increased the cost of family education expenditures since China’s reform and opening up, which further aggravates the negative impact on education of having many siblings in an urban setting.  相似文献

Basic skill requirements for selected Army occupational training courses     

Nancy K. Moore  Margaret T. Shaffer  Rita Furst Seifert 《Contemporary educational psychology》1985,10(1):83-92

This study investigated the basic cognitive skills soldiers must possess before entering the Army, skills that are needed for successful completion of entry-level training. Judgments of 126 instructors from 25 military occupational specialties were obtained on 129 candidate skills, which resulted in the identification of 55 basic skills. Factor analysis of these 55 skill items resulted in 11 interpretable factors. Mean scores on the factors were compared across factors and across Army training schools. The results of the study suggest that, for all occupational specialties studied, skills related to the learning process are as crucial as traditional academic skills for successful training course completion. These results have important implications for training for the Army as well as for industry.  相似文献

Hebe Schaillée  Reinhard Haudenhuyse  Lieve Bradt 《Sport in Society》2019,22(6):885-896

Abstract

This opening article examines the relationship between community sport and social inclusion in research and practice. We discuss the notion of community sport, its multifarious meanings and diverse applications in different parts of the world. We further explore the conceptual and practical links between community sport and different conceptions of social inclusion. In doing so, the article draws together key themes, issues and debates addressed in the collection of articles in this special issue. We conclude by formulating implications and directions for future research and practice.  相似文献   

英国新学习文化运动的宣言书——《21世纪的学习》述评及启示     

马爱民 《外国教育研究》2007,34(4):1-6

新学习文化的创建和发展是终身学习深入发展的必然趋势,日益受到各发达国家的重视。英国在新学习文化的研究和实践方面都走在世界前列,自1997年以来先后出台了一系列相关报告,发起了一场新学习文化运动。其中《21世纪的学习》是发表最早,也是影响最深远的报告,可谓英国新学习文化运动的宣言书。目前中国在新学习文化方面的研究十分匮乏,有必要学习借鉴英国在发展新学习文化方面的实践,最终形成和发展符合中国国情的新学习文化,以逐步实现学习型社会。  相似文献
