Abstract During the first ten days of the academic year the Physical Estimation and Attraction Scales (PEAS) and Bialer's Locus of Control Scale were administered to seventh and eighth grade middle school males. Subsequently, calls were issued for the fall sport season (flag football, cross-country). Stepwise discriminant analysis produced a function containing Attraction first and Estimation second, which accurately predicted athletic participation, canonical r = .35 p < .001. Use of smaller, previously factored collections of PEAS items improved the prediction, canonical r = .40, p < .001. Prediction of a single, more specific activity, cross-country, by means of the more specific factor scores produced a canonical coefficient of .47, p < .001. PEAS Factor 5, referring primarily to activities of running and hiking, developed the largest relationship with cross-country participation of any study variable. Control did not enter either of these two equations. No significant relationship was found between any study variable and adherence (remaining on the cross-country team for the complete season). It was concluded that PEAS variables are capable of predicting initial exercise involvement. In terms of developing optimal psychometric predictions of exercise recruitment and adherence, it is recommended that attitude statements be developed which are more specific and congruent to corresponding desired behaviors. 相似文献

In social constructivist educational theory, the classroom is seen as a community of learners. According to social constructivists, learning occurs through peer interactions, student ownership of the curriculum and educational experiences that are authentic for students. The purpose of this study was to investigate how teachers used social constructivist strategies to encourage student construction of knowledge and meanings, and how students constructed knowledge and meanings in two middle school physical education classrooms. A qualitative naturalistic design was used to collect data over a five-month period with two experienced middle school physical education teachers. Data included 11 weeks of observational field notes and interviews with teachers and students. Data were analyzed using cross-case and inductive analysis. Findings indicated that the teachers' strategies created a learning environment in which students actively constructed knowledge and meanings by making connections to their peers and by connecting physical education to their lives, their communities, and the real world. Students shared information, assumed leadership and responsibility, and became decision-makers. By connecting to their peers, students felt supported in their learning. This study offers additional findings in support of social constructivist pedagogy in physical education that encourages individual growth and social awareness in communities of learners. 相似文献

In recent years there has been a growing interest in arming physical education teachers with critical pedagogies. The purpose of this study was to determine the influence of a critically oriented methods course and early field experience (EFE) on 20 preservice teachers' (PTs) conceptions of the teaching–learning process. Data were collected using the critical incident technique and a reflective questionnaire. They were analyzed by employing the analytic induction method. Results indicated that the inward focus of the methods course and EFE on the analysis of teaching had a considerable influence on the PTs. Conversely, the outward focus on curriculum studies as well as four permeating themes (elitism, racism, classism, and sexism) appeared to have virtually no impact on them at all. Possible reasons for and implications of these findings are discussed. 相似文献

和日常社会生活过程一样，社会的变迁过程也是一个具有高度复杂性的过程。吉登斯、莫兰等人对此都做过一定的论述，但他们的论述都有局限性。本以美国学皮奥雷和撒贝尔有关现代工业生产技术变迁的一项研究成果为例，具体分析和说明了应该怎样全面准确地描述和理解社会变迁过程的复杂性。 相似文献

贵族作为社会特权阶层,是史前社会复杂化的产物.它滥觞于中石器时代,形成于新石器时代晚期.从产生之日起,贵族便合法掌控了世俗和宗教特权.其地位合法化的实现主要归因于“习惯性认可”和“制度性规范”两大因素.二者相互作用,共同保障了贵族地位合法性的延续. 相似文献
