Purpose: The purpose of this study was to determine the extent to which a sport education season of fitness could provide students with recommended levels of in-class moderate-to-vigorous physical activity (MVPA) while also increasing students’ fitness knowledge and fitness achievement. Method: One hundred and sixty-six 5th-grade students (76 boys, 90 girls) participated in a 20-lesson season called “CrossFit Challenge” during a 4-week period. The Progressive Aerobic Cardiovascular Endurance Run, push-ups, and curl-ups tests of the FITNESSGRAM® were used to assess fitness at pretest and posttest, while fitness knowledge was assessed through a validated, grade-appropriate test of health-related fitness knowledge (HRF). Physical activity was measured with Actigraph GT3X triaxial accelerometers. Results: Results indicated a significant time effect for all fitness tests and the knowledge test. Across the entire season, the students spent an average of 54.5% of lesson time engaged in MVPA, irrespective of the type of lesson (instruction, free practice, or competition). Conclusions: The results suggest that configuring the key principles of sport education within a unit of fitness is an efficient model for providing students with the opportunity to improve fitness skill and HRF knowledge while attaining recommended levels of MVPA. 相似文献

This article describes a laboratory servomechanism and an associated laboratory sequence which were designed to complement theoretical first courses in servomechanisms at either senior-year undergraduate or first-year graduate level. The primary aims were to provide the student with the means for an experimental verification of theoretical results and, at the same time, to encourage him to establish some feeling for the physical reality of an operating feedback system. 相似文献

The purposes of this study were to describe and compare the specific physical activity choices and sedentary pursuits of African American and Caucasian American girls. Participants were 1,124 African American and 1,068 Caucasian American eighth-grade students from 31 middle schools. The 3-Day Physical Activity Recall (3DPAR) was used to measure participation in physical activities and sedentary pursuits. The most frequently reported physical activities were walking, basketball, jogging or running, bicycling, and social dancing. Differences between groups were found in 11 physical activities and 3 sedentary pursuits. Participation rates were higher in African American girls (p < or = .001) for social dancing, basketball, watching television, and church attendance but lower in calisthenics, ballet and other dance, jogging or running, rollerblading, soccer, softball or baseball, using an exercise machine, swimming, and homework. Cultural differences of groups should be considered when planning interventions to promote physical activity. 相似文献

Empirical evidence suggests that a domain-specific coping style may play an important role in the way students manage stressful academic events and perform at college. The purpose of this research was to examine the extent to which college students' academic coping style and motivation mediate their academic stress and performance. A structural equation analysis showed that the relationship between college students' academic stress and course grade was influenced by problem-focused coping and motivation but not emotion-focused coping. As expected, greater academic stress covaried with lower course grades; however, students who engaged in problem-focused coping were more likely to be motivated and perform better than students who engaged in emotion-focused coping. Strategies for promoting more effective coping in college students are discussed. 相似文献

This article describes a situative approach to studying motivation to learn in social contexts. We begin by contrasting this perspective to more prevalent psychological approaches to the study of motivation, describing epistemological and methodological differences that have constrained conversation between theoretical groups. We elaborate on issues of the unit of analysis, the conceptualization of contexts, and the role of identity as a central construct. Finally, we argue that the design of learning environments and interventions to change learning environments are informed by attention to the relationships among meanings, identities, and motives in context. We illustrate our argument with examples of design-based research and design-based implementation research focused on motivation to learn in children and adults. 相似文献
