选取在国际上有代表性的美国及亚洲的新加坡与中国的小学及初中数学课程标准为研究对象,从内容分布与认知要求两个维度进行编码比较研究。主要研究结果显示三国数学课程标准分别呈现如下特征:中国在内容维度上,几何内容拥有的认知要求最多,在认知要求维度上最重视数学推理,并且数学推理主要是以几何内容为主要载体的;美国和新加坡在内容维度上,数与代数拥有最多而丰富的各类认知要求,在认知要求维度上两国均十分重视“问题解决”,美国还重视“关联”类认知要求。  相似文献

Given that physical activity (PA) tends to decrease with age during adolescence, addressing factors that affect change is important. This study examined the similarity and interdependence of PA as influenced by psychosocial factors among adolescent best friend dyads. A total of 660 adolescents, representing 330 best friend dyads, completed questionnaires with regard to PA, sitting time, perceived exercise benefits and barriers, physical self-perception and social support for PA. Dyads were also identified as reciprocal and non-reciprocal best friends; reciprocal means that both considered each other best friends and non-reciprocal were those in which only one considered the other a best friend. Data were analysed using a hierarchical linear model framework. Results indicated significant similarities between reciprocal best friend dyads for PA and sitting time, and for sitting time in non-reciprocal best friends (P values <.01). Psychosocial variables were associated with PA in reciprocal best friend dyads and with sitting time in reciprocal and non-reciprocal best friend dyads. Best friend gender, regular sports practice of the person, perceived exercise barriers of the best friend and best friend social support were the best predictors for PA.  相似文献

Abstract

This paper examines the confluence of global, regional, and national politics in the lead up to the 1991 Pan-American Games hosted by Cuba. Cuba’s contentious selection as host was wholly underpinned by the international politics of the time. Once selected, the preparations for the Games in Havana were surrounded by an unprecedented domestic economic crisis fueled by shifts in global politics. This paper analyzes how international politics informed the hosting of the 1991 Pan-American Games, and shaped the political challenge the Cuban government faced in hosting such an event. The Revolution’s use of sport domestically and internationally came to the forefront in its efforts as host and the results of those efforts proved to be providential given the emerging political economic contexts during and in the ensuing years after the Games.  相似文献

Abstract

This paper explores the migration of female basketball players from Taiwan to China. Governance theory is adopted as the framework in this study to analyze the phenomenon of players’ migration and to understand how it was shaped over the years. The empirical work draws on a qualitative approach, which is based on a review of documentary materials and semi-structured interviews; coding and analysis were undertaken with a content analysis approach in order to investigate the decision-making processes and their consequences for the players’ migration. The feature of systematic governance for the development of women’s basketball has been revealed in this study. Stakeholders with personal interests caused the downturn of women’s basketball development in Taiwan, and it eventually led to the players’ migration abroad. Through the lens of governance theory, it has been revealed that a number of factors – namely, political, financial, personal, socio-economic, and cultural – all intertwine with one another dynamically to influence the female players’ decision to move abroad. This finding broadens the scope for the research of Taiwanese athletes’ migration to China, extending the focus from only business or industry to other aspects, thereby highlighting the fact that the subject is more complex than previously understood.  相似文献

Sit–stand workstations offer a potential strategy to reduce prolonged occupational sitting. This controlled intervention study examined the effects of an environmental intervention on occupational sedentary time, musculoskeletal comfort and work ability, and the usability of sit–stand workstations in office work via a self-reported questionnaire. The intervention group (n?=?24) used sit–stand workstations during the 6-month intervention period, and the control group (n?=?21) used traditional sitting workstations. The results showed that working at sit–stand workstations can reduce sitting time significantly compared to control workstations (?6.7% vs. 5.0%, p?=?.019), which is reallocated mostly to standing (r?=??0.719, p?p?=?.028), as well as work ability (p?=?.022). The majority of intervention subjects rated sit–stand workstation adjustability as good (83.3%), and 75.0% were satisfied with the workstation. About 41.7% of the intervention participants, who were exclusively female, used the sit–stand function on a daily basis. While the environmental change alone was effective, it is likely that promoting the daily use of sit–stand workstations with counselling would lead to even more substantial positive effects.  相似文献
