Schools represent an ideal environment for increasing sports participation, but it is unclear how access and choice influence participation and whether characteristics of the school sports program differentially influence boys＇ and girls＇ participation. The purpose of this study was to evaluate the characteristics of high school athletic programs and determine the extent to which these characteristics influenced boys＇ and girls＇ sports team participation. Methods： Longitudinal telephone surveys were conducted with 1244 New Hampshire and Vermont students. Students self-reported their sports team participation at baseline （elementary school） and follow-up （high school）. High school personnel were surveyed to assess sports oppor- tunities, which were defined for this analysis as the number of sports offered per 100 students （i.e., choice） and the percent of sports offered that did not restrict the number of players （i.e., access）. Results： Approximately 70% of children participated on at least one sports team, including 73% of boys and 66% of girls. We detected sta- tistically significant interactions between sex and two school opportunity variables： 1） the number of sports offered per 100 students （i.e., choice） and 2） the percent of sports offered that did not restrict the number of players （i.e., access）. After controlling for children＇s baseline sports participation and other covariates, boys were more likely to play on at least one sports team per year if their school did not restrict participation in the most popular sports （relative risk, RR = 1.12, p 〈 0.01）; in contrast, girls were more likely to play on at least one sports team per year if their school offered a wider variety of sports （RR = 1.47, p 〈 0.001）. Conclusion： Sports participation has previously been shown to confer a number of health benefits; as such, school sports programs may be an important, effective, and underused target for public health efforts, including obesity prevention programs. Efforts to increase physical activity among youth should consider both access and choice in school athletic programs. Schools may need to use different strategies to increase sports participation in boys and girls.展开更多

Philosophy in school, on the one hand, is a progressive discussion about our future educational system so that it can provide safe training about how philosophy can be performed and mixed in school classes and auditoriums. Therefore, philosophy for children explains that how each teacher in each subject is able to accept a model of philosophical search and adapt it to the class situation. Philosophy is much better understood if considered as a public activity and a conversation according to what Socrates did, than just considered as an education subject which should be inserted in child＇s memory. On the other hand, philosophical opening, questioning, and surprising toward the word--the characteristics which are undeniable, admirable, and comprehensive----can be remained superficial and even bare. Unless, it founts from Socrates＇ dialectic insight： ＂I know that I don＇t know.＂ Philosophy for children is a program which involves them in every class discussion in the field of philosophical subjects. The aim of this program is the improvement of children though via introducing them numerous ＂Big Question＂ and enables them in considering these questions. Using this program, teachers encourage children to think more deeply on ideas about their schoolwork. This strategy mainly takes place in project community of classes. Children will deeply concentrate on their thoughts and skill and then improve them while considering and reinforcing their own and others＇ ideas in response to philosophical puzzles. This article aims to reply the following questions： What is philosophy for children？ What aims does it follow？ What is its content？ What skills does it consider？ How does it compose with the current educational programming？ What strategies does this curriculum follow？展开更多

This corporation emerged from the recognition of the strategic importance of science and necessity of institutionalization of encouragement and fostering research. This is a theoretical bibliographical study and documentary that evidences the contributions and limits of SI while political science training should be part of academic activities to provide the development and support of investigative spirit. The concept of SI was established in universities as an activity to be developed in order to encourage the student to become familiar with scientific practices. The study concluded that SI is based on institutionalized norms within higher education to foster the development of science, and it is considered as an important strategy of expansion of graduate studies in Brazil.展开更多
