Opportunities for children to be physically active during school time are sparse and becoming increasingly so. The purpose of this investigation was to determine if children would compensate for school days (9 a.m.-3 p.m.) of restricted physical activity opportunities by increasing activity levels after school (3 p.m.-7:30 p.m.). Third and fourth grade children (N = 76) each wore a CSA accelerometer for 4 nonconsecutive days. Two days were categorized as active--during school, all children participated in outdoor recess and physical education class. Two days were categorized as restricted--all children spent their recess time indoors at a computer terminal, and no physical education class was scheduled. Dependent t tests revealed that children did not compensate for a sedentary school day by increasing their levels of physical activity after school. In fact, average movement counts per minute were higher in the 3 p.m.-7:30 p.m. period following the active day (525 counts.min-1) versus the restricted day (186 counts.min-1). These findings suggest cause for concern if children's opportunities to be active within school time are limited. Several reasons are given as to why children did not compensate or "make up" for the physical activity opportunities missed during the restricted school day. 相似文献

This paper explores the notion of the 'evidence-based practitioner' in relation to the National Numeracy Strategy (NNS). The exploration is dealt with in the context of a pilot study of the implementation of the NNS one year before its national launch in September 1999. We begin by describing some of the milestones encountered in the relatively short life history of evidence-based practice (EBP) and exploring some of its various articulations. Challenging the appropriateness of current externally derived formulations of 'evidence' we develop the notion of 'warranting' in order to examine alternative ways in which teachers legitimate their professional practice in relation to the NNS. We conclude that what we observe is a series of shifting and multiple meanings and justifications, carrying different constraints and possibilities for practice. 相似文献

Achievement and underachievement in able children were investigated in three schools in the South of England. Phenomenological techniques were used to explore teachers', parents' and pupils' behaviour and perspectives. Models of achievers and underachievers which arose out of this research were compared with the literature. Particularly important factors which contributed to the children's achievement were supportive parents and teachers who acted in cooperation, although the child also had to have good skills of concentration and presentation, task commitment, high self-esteem and the ability to relate well to peers. In contrast, achievement was demonstrated to be limited when various combinations of these factors were missing. Sample vignettes of participant children are provided to illustrate these points. 相似文献

Delphine Hanna was a pioneer in both disciplinary scholarship and the establishment of professional programs. In this paper I contend that we must follow her example if we are to survive in the 21st century. In the past half century we have evolved from a profession primarily associated with teaching to a group of subdisciplines and many different professions. We got where we are as we both reacted to criticism and conformed to university concepts of centrality. For optimal development of both the disciplines and professions of kinesiology/physical education, it is suggested that we must become a field that includes both the disciplines and professions. The field should reward the many different roles equally in the pursuit of its common goals. We learn from nature and history that working together is critical for survival. By working together, we can make kinesiology/physical education the renaissance field of the 21st century. 相似文献

This article traces the history of the Conceptual Physical Education (CPE) movement and the important role this movement has played in college and university physical education departments in America over the past 50 years. CPE emerged out of basic instruction programs (i.e., skill-based, activity classes) during an era characterized by the accumulation of a large body of scientific evidence regarding the health benefits of physical activity, the formation of subdisciplinary areas of study, and a dramatically changing curriculum in higher education. CPE merges the practice and science of the field through a lecture-laboratory approach. First introduced in the 1960s by innovators, CPE classes are now offered by most college and university physical education programs in the United States, suggesting that CPE is a true innovation, rather than simply a passing fad. 相似文献

The American professoriate is shifting its majority makeup from tenure track to non-tenure track faculty members. Less known, though, is what the implications of this shift are for students’ course experiences. We sought to examine the extent to which the teaching practices, with regard to academic rigor and cognitively responsive teaching, differ between faculty category using observational measures of teaching in the classroom. We found that broad categorizations of faculty may not be meaningful unless they are examined in particular contexts, such as discipline and class size. 相似文献

Sedentary women (n = 92) classified as low (L), medium (M), and high (H) in baseline step counts and assigned to 10,000-step goal (TSG) and personal step goal (PSG) groups (within levels) were compared on goal attainment and step counts. A significant interaction for goal attainment, F(2, 86) = 4.51, p = .014, indicated that the L group was significantly less likely to meet the TSG than the M and H groups. Step counts increased after goal assignment, but not more for one group than the other. Results of this research support the previous finding that women with low baseline step counts are unlikely to meet a TSG, but a TSG does not result in lower step counts than a PSG. 相似文献

The purpose of this study was to determine whether taking 10,000 steps in a day is equivalent to meeting the current minimum physical activity guidelines of accumulating at least 30 min of moderate physical activity (IMPA). Fifty-nine women ages 20-65 years wore a pedometer and accelerometer concurrently on their right hip for 1 day. There were no differences in the age, body mass index, or the amount of time the pedometers and accelerometers were worn between the 10K+ and the < 10K groups. The 10K+ group accumulated significantly more steps and minutes of MPA than the < 10K group (M = 13,084 steps, SD = 2,603 vs. M = 7,518 steps, SD = 1,956; and M = 62.1 min, SD = 27.7 vs. M = 38.8 min, SD = 18.9; p < .05). A 2 x 2 chi-square analysis demonstrated no difference between the proportions of 10K and < 10K participants who met the step goal, when all minutes of MPA accumulated throughout the day were considered (chi2 = 1.8, df = 1, p = .175). When only continuous bouts of MPA lasting > 5 min and > 10 min were considered, a significantly greater proportion of 10K participants met the current physical activity guidelines than the < 10K participants (chi2 = 11.5, df = 1, p = .001, and chi2 = 5.9, df = 1, p = .015, respectively). Our finding, suggest that individuals who accumulate 10,000 steps/day are more likely to meet the current physical activity guidelines by engaging in the length of bouts promoted by the Centers for Disease Control and Prevention and the American College of Sports Medicine (Pate et al., 1995) and the US Surgeon General (U.S. Department of Health and Human Services, 1996). However, the data also reveal that accumulating 10,000 steps/day does not guarantee meeting the guidelines in the bout lengths documented to confer the health benefits of physical activity. 相似文献
