Purpose: A relationship exists between attitudes toward physical education and future physical activity. The purpose of this study was to examine changes in attitude toward physical education as students progressed from upper elementary school (Grade 4) through middle school (Grade 8). Method: Three cohorts of students (Cohort 1, Grades 4–6, = 96; Cohort 2, Grades 5–7, = 71; and Cohort 3, Grades 6–8, = 73) were each followed for 3 years to examine changes in attitudes toward physical education. Results: After an initial increase from Grade 4 to Grade 5, a significant decrease was observed from Grades 5 to 8 in students’ positive attitudes toward physical education, with a faster rate of change for girls than boys. Conclusion: This longitudinal study provides further insights regarding the attitudes of students as they progress from Grade 4 to Grade 8 and expands on previous findings identifying decreasing positive attitudes toward physical education as students age, particularly for girls. The results provide evidence to support targeted interventions.  相似文献

Research illustrates the positive roles of perceived competence, autonomy, and mastery climate and the negative role of performance climate in student motivation in physical education. Less research has examined perceptions of relationships within this setting (i.e., perceived teacher support and relatedness) and their role in student motivation. The purpose of this study was to test the mediating roles of perceived competence, autonomy, and relatedness in the relationship between social contextual factors and motivation in physical education students (N = 508). Results from structural equation modeling showed that perceived competence, autonomy, and relatedness partially mediated the relationship between perceived teacher support and self-determined motivation and that mastery climate related directly to self-determined motivation. The results highlight the importance of perceived teacher support, mastery climate, and relatedness to motivation in physical education.  相似文献

Females and youth are frequently described as "special" populations in football literature, but together these two populations outnumber male players. What makes females "special" is that they tend to eat less when training and competing than their male counterparts, leading to lower intakes of energy, carbohydrate, and some nutrients. Youth football players are special in regard to energy and nutrient requirements to promote growth and development, as well as to fuel sport. There is limited research on the dietary habits of these two populations, but the available literature suggests that many female and youth players need to increase carbohydrate intake, increase fluid intake, and develop dietary habits to sustain the demands of training and competition.  相似文献

One aspect of human resources development in which performance technologists are frequently involved is the establishment of selection procedures and criteria. There is a trend toward increased use of standardized tests in the selection process. A performance technologist might be involved in the selection of, or development of, tests for screening of applicants. Alex L. Chew and John D. Morris in their article “Investigation of the Lollipop Test as a Pre-Kindergarten Screening Instrument” provide a useful review of validation procedures.  相似文献

This study hypothesized that: (a) the MSSST would identify the same proportion (15%) of high-risk children in a group (N = 580) of first-grade urban black children as estimated for the general population; (b) the Myklebust would discriminate between high-risk (N = 22) and low-risk (N = 21) children within the minority group using the MSSST as the criterion variable; and (c) Myklebust ratings for the high-risk and low-risk young minority children would approximate ratings reported elsewhere for older white suburban samples of high-risk and low-risk children. All three hypotheses were confirmed. The MSSST may be appropriate for minority group children. The small number of teachers (N = 6) participating in the Myklebust ratings makes generalization about it hazardous without further replication.  相似文献
