Purpose: Even though physical education (PE) is an evidence-based strategy for providing and promoting physical activity, alternative programs such as the Junior Reserve Officer Training Corps (JROTC) are commonly substituted for PE in many states. The purpose of this study was to compare student physical activity and lesson contexts during high school PE and JROTC sessions. Method: The System for Observing Fitness Instruction Time was used to assess PE and JROTC sessions (N = 38 each) in 4 high schools that provided both programs. Data were analyzed using t tests, negative binomial regression, and logistic regression. Results: Students engaged in significantly more moderate-to-vigorous physical activity during PE than during JROTC sessions and they were significantly less sedentary. Significant differences between the 2 program types were also found among lesson contexts. Conclusions: PE and JROTC provide substantially different content and contexts, and students in these programs engage in substantially different amounts of moderate-to-vigorous physical activity. Students in JROTC, and perhaps other alternative programs, are less likely to accrue health-supporting physical activity and engage in fewer opportunities to be physically fit and motorically skilled. Policies and practices for providing substitutions for PE should be carefully examined. 相似文献

Abstract This study investigated the effects of sex and athletic status on reaction latencies and movement time. One hundred subjects, categorized into five groups of 20 subjects each—male athletes (MA), female athletes (FA), male nonathletes (MNA), female nonathletes (FNA), and control group (CG)—were tested over a period of five consecutive days. Several different types of incentives were used to ensure that subjects provided the fastest times possible. Two blocks of 25 trials were administered to each subject on each day. A 2 × 2 × 2 × 5 × 2 mixed factorial analysis of variance was used to test for between-subject differences of group (experimental/control), sex, and athletic status and for within-subject differences of days and blocks. The four dependent variables were reaction time (RT) mean, RT consistency, movement time (MT) mean, and MT consistency. Results did not support the classic finding of male superiority over females in RT/MT or athletes' superiority over nonathletes. Evidence of athletic superiority emerged, but for the first day of practice only. As subjects were allowed extended practice over a 5-day test period in which knowledge of results (KR) and other incentives were provided, differences in the experimental groups disappeared. Sex was the predominant factor in consistency, with males being less variable in RT (p = .02) performance than females. There were no sex differences in MT consistency. 相似文献

There are substantial pressures for changes in teaching practice which are now clearly reflected in government policy. It is argued that these pressures have emerged from changes in the culture of technologically based societies and the resulting changes in the needs of all students in schools. The implications of recent theories of learning and new needs for learners are discussed with respect to teacher education. An attempt to change the way in which students are prepared in mathematics education is reported. Data collected as part of the study indicate the need for a system‐wide approach to change. 相似文献

One reason we have difficulty finding sustainable solutions is in part because we are unable to see the bigger picture. Capra (2000) argues, “To become ecologically literate we must learn to think systemically – in terms of connectedness, context and processes” (p. 270). We have attempted to structure connected learning experiences through our transdisciplinary approach to teaching for learning science, mathematics and ecological aspects of society and environment. We support Jucker's (2002) view that we must have lateral rigor across disciplines and vertical rigor within disciplines in order to best prepare students for teaching. This paper explores the theoretical underpinning of this complex approach to undergraduate teaching and reports on how our teaching team has worked collaboratively to structure a sequence of three, one semester integrated, core courses that explicitly uses an educating for ecological sustainability theme as the basis for each course and associated assessment. 相似文献

Season of birth is related to child retention rates, achievement, and rate of diagnosis of specific LD 总被引:1,自引:0,他引:1
A sizable literature has demonstrated that the achievement of children in early elementary school is related to their season of birth: Those born in summer typically perform less well than those born in the fall. A small literature indicates that more children diagnosed with specific learning disabilities (SLD) are born in the summer. We have begun to explore the possibility that the same processes may account for both outcomes. In order to better understand these processes, the standardized achievement levels and rates of diagnosis of SLD for children born during each season were studied in one geographical area of the State of Georgia served by 28 school districts. Standardized achievement scores in reading, mathematics, and science were reliably lower for those born in the summer. Furthermore, there was a strong relationship between season of birth and the rate at which children received a diagnosis of SLD. Summer-born children were diagnosed with SLD at a higher rate than their peers. Four hypotheses for both the lower performance in the general school population and the greater rate of SLD diagnosis among these children are discussed. 相似文献

Drawing from literature on communication as a physical, material experience, this article expands Cargile Cook’s “layered literacies” (2002) pedagogical framework to include a seventh literacy—embodied literacy. The article uses a classroom case study in which students coproduced a cookbook with low-income, elderly, disabled users, to demonstrate how students can become more responsible and effective technical communicators by recognizing users’ divergent embodied experiences. The article includes suggestions for concrete classroom practices that encourage such embodied literacy. 相似文献

The New Zealand Ministry of Education has introduced a Numeracy Project for students aged 5–14 years in selected schools. The project encourages the adoption of flexible strategies for solving numerical problems, and discourages reliance on standard computational algorithms. One potential benefit of the project is that the methods students acquire in the project may provide a foundation for algebraic thinking through the use of quasi-variables in numerical operations. In order to evaluate this possibility, we constructed a 21-item test of numerical manipulation that required an underlying awareness of the presence of quasi-variables. The test was administered to 431 12-year-old students who participated in the project and to 468 students who did not. The test consisted of six sections, each of which examined the application of a different aspect of reasoning to numerical problems. The results showed that students who participated in the Numeracy Project solved numerical problems that required manipulation with more success than did students who had not participated in the project. This proved to be the case for three different levels of analysis: for the test as a whole, for each of the six sections of the test, and for every individual item of the test. The results were interpreted as showing that the project fostered students awareness of numbers as quasi-variables and thus provided an early indicator of algebraic thinking. 相似文献

The review acknowledges that research on the family and its contribution to achievement in ethnic minority children is important. Past research and theorizing suggest the need for new directions, however. For example, research in educational achievement predicts educational failure for African-American students and educational success for Asian-American students. Little differentiation is made either among African-Americans or among Asian-Americans of different cultural, language, immigration, and economic backgrounds. The theory and design of research on family and educational achievement have been influenced by prevailing societal stereotypes. Research and policy implications of this review include the need to move toward cultural/ecological theories of achievement socialization and development. 相似文献
