Elementary school teachers' perception of desirable learning activities: a Singaporean perspective     

Ai-Girl Tan 《Educational research; a review for teachers and all concerned with progress in education》2013,55(1):47-61

A total 209 teachers (103 initial and 106 experienced) of various elementary schools in Singapore rated the perceived children's desirable learning activities on a five-point Likert scale. Four factors emerged (50.5 per cent variance): conventional learning activities; motivational activities; student-directed activities that foster independence and collaboration; and teacher-directed group activities. Two clusters were formed: motivational learning activities, and all kinds of learning activities. About half of the initial teachers belonged to each of the clusters, while the majority of experienced teachers (83 per cent) belonged to the latter cluster. Multivariate analysis of variance on the items yielded a main significant effect for initial and experienced teachers. Implications of the study for Singaporean classroom learning are presented.  相似文献   

Pedagogical distance: explaining misalignment in student-driven online learning activities using Activity Theory     

Nicola Westberry 《Teaching in Higher Education》2013,18(3):300-312

This paper provides an Activity Theory analysis of two online student-driven interactive learning activities to interrogate assumptions that such groups can effectively learn in the absence of the teacher. Such an analysis conceptualises learning tasks as constructed objects that drive pedagogical activity. The analysis shows a disconnect between the codified curriculum plan and its actual enactment, and a misalignment of interpretations of the object by different participants in the activity. We name this ‘pedagogical distance’. We argue that a teaching presence is important to guide both student and tutor interpretations of the learning task, and offer suggestions for decreasing pedagogical distance.  相似文献   

南京市部分业余体校运动员参训动机分析     

滕勇  王雪峰 《福建体育科技》2013,(6):56-57,60

运用文献资料、调研、访谈、专家咨询、问卷调查等方法,对南京市部分业余体校314名运动员的参训动机进行调查分析。主要结论：功利性的和世俗性的动机、意愿是受现代社会因素和时代影响。这表明学生及家长对参加竞技体育训练多是为孩子将来的职业考虑,希望通过竞技体育这条道路能够获得更高的荣誉、奖金,或成为一种职业,晋升到社会的中上阶层;应加强爱国主义教育,培养为国争光的荣誉感;鉴于运动员家庭对子女参加竞技体育训练的期望,为其将来的职业选择准备条件。  相似文献   

关于高校体育课内与课外结合的思考   总被引：7，自引：0，他引：7  

任宏权 《四川体育科学》2002,(1):61-62

针对高校体育中重视课内体育教学，忽视课外锻炼的现象，从论证两者关系的角度入手，揭示出课内与课外不仅有着互相联系、相互补充的关系，还存在着互相影响、互相作用、服务与被服务、检验与被检验的关系；揭示出没有高校体育课内与课外的结合，便没有高校体育与社会体育的结合：揭示出“让学生运动起来”是高校体育要实现的首要目标。  相似文献

Physical activity is important in obesity prevention, but the effectiveness of different physical activity modalities remains to be determined among children. The main purpose of this study was to compare the effects of a 6-month soccer programme and a traditional physical activity programme on changes in body composition, cardiometabolic risk factors, inflammatory and oxidative markers, cardiorespiratory fitness and perceived psychological status in obese boys. Eighty-eight boys (8–12 years; BMI > +2 standard deviations of WHO reference values) participated in one of three groups: soccer, traditional activity and control. Soccer and traditional activity programmes involved 3 sessions per week for 60–90 min at an average intensity of 70–80% of maximal heart rate. Control group participated in activities of normal daily living. All boys participated in school physical education, two sessions per week of 45–90-min. Measurements were taken at baseline and after 6 months, and included body size and composition, cardiometabolic risk factors, inflammatory and oxidative markers, cardiorespiratory fitness and perceived psychological status. Physical activity and dietary intake were assessed before and immediately following the intervention. The three groups had similar characteristics at baseline. After 6 months, both intervention groups had significantly lower relative fatness (% fat), waist circumference and total cholesterol, and higher cardiorespiratory fitness, self-esteem, perceived physical competence and attraction to physical activity compared with control group. In conclusion, physical activity interventions over 6 months positively influenced several indicators of health status among obese boys. The results also suggested that soccer has the potential as an effective tool for the prevention and reduction of childhood obesity and associated consequences.  相似文献
