Abstract

The purpose of this study was to investigate differences between the oversized racquet and the standard-sized racquet in (1) a tennis shot accuracy test on four basic strokes (ground strokes, volley, return of serve, and serve), and (2) a measure of players' subjective evaluation of playability (control, accuracy, power, and feel). Research participants (n = 57) were undergraduate students separated into two skill levels, intermediate (n = 29) and beginners (n = 28). Data were analyzed using a two-factor ANOVA with repeated measures on one factor. Result from the skills tests indicated that both beginning and intermediate groups scores significantly higher when using the oversized racquet. The scores received when using the oversized racquet tended to reflect a general increase in all four components of the skill test, particularly the return of serve. Data indicated that the subjective evaluation of the playing characteristic of each racquet was influenced by the player's skill level. Beginning players favored the oversized racquet, yet intermediate players rated the two racquet types about equal. The investigation suggests that beginning and intermediate tennis players, educators, and tennis teaching professionals should consider using and encouraging the use of oversized racquets.  相似文献

Abstract

The Sport Orientation Questionnaire (SOQ) was developed as a multidimensional, sport-specific measure of individual differences in sport achievement orientation. Exploratory and confirmatory factor analyses revealed a stable, three-factor structure across three separate samples of university and high school students. The three separate but related subscales of competitiveness, win, and goal orientation demonstrate high internal consistency and stability over time. The SOQ competitiveness score differentiates students in competitive activities from those in noncompetitive activities, providing evidence for construct validity. The overall factor stability, reliability and validity evidence suggests that the SOQ can be a valuable measure for the investigation of competitiveness and achievement behavior in sport and exercise settings.  相似文献

Abstract

Two experiments were conducted to investigate the effects of competition and instructional sets on the speed and accuracy of a dart-throwing task. In both experiments individuals competed against another subject on one day, and performed under noncompetitive conditions on a second day. The five distinct instructional sets varied from extreme emphasis on speed to extreme emphasis on accuracy. Multivariate analyses of variance revealed main effects for instructional sets on speed and accuracy in both experiments. Strong tradeoffs occurred with speed slowing and accuracy improving as the instructional emphasis changed from speed to accuracy. A competition by instructional sets interaction in Experiment 2 indicated that competition facilitated speed when speed was important, but when instructions emphasized accuracy, speed was slower in competition than in noncompetition. Accuracy was not affected by competition.  相似文献

Data gathered as part of a recent research project into the provision of collective worship in schools in England and Wales reveals the existence of a marked variation in approach and provision between schools in the primary and secondary sectors. Consequently, the point of transfer often becomes a watershed in pupils’ experience. This sudden change, which is most apparent in community schools, is accompanied by a slower but pre-existing transition in attitudes which is common to pupils in all types of institution. Using material gathered from interviews with young people, this article examines the issue of participation in school worship from the pupils’ perspective and analyses the reasons they give for their opposition to provision. It then compares these attitudes with those of a previous generation, as demonstrated in the work of Loukes (1961 Loukes H (1961) Teenage Religion (London, SCM)  [Google Scholar]) and Goldman (1964 Goldman R (1964) Religious Thinking from Childhood to Adolescence (London, Routledge & Kegan Paul)  [Google Scholar], 1965 Goldman R (1965) Readiness for Religion (London, Routledge & Kegan Paul)  [Google Scholar]) in order to explore the underlying changes which influence students’ thinking. It concludes with a consideration of the implications of these findings for practice and policy.  相似文献

Since the early years of the twenty‐first century there has been an increasing interest in using Web 2.0 technologies to support learning in Higher Education. However, previous research suggests that the integration of blogging into courses can be difficult and cites problems with issues such as student compliance. We adopt a learner‐centred perspective and explore students’ (rather than their educators’) understanding of how blogs and blogging can support distance learning in Higher Education. We report on a study of UK Open University (OU) students on an online distance learning Masters course, that has enabled us to determine the issues that are important to these bloggers, and we describe five ways in which they appropriated blogging to suit their individual needs. We discuss the importance of making blogging activities flexible so that students can blog to meet their own needs whilst still attending to the requirements of their course.  相似文献

Breast cancer is one of the most feared diseases in contemporary Western society. Popular women's magazines are important sources of information about and orientation to the disease. The current study applies problematic integration theory in an interpretive analysis of all breast cancer articles appearing in five top-circulating women's magazines between 1997 and 2002. In so doing, the study illuminates two major challenges (uncertainty and ambivalence) and several imperfect approaches to coping constructed in this discourse (simplification, information-seeking/provision, affect management, trusting intuition, sustaining hope, and metaphoric reframing). These results have several clear and important practical implications and highlight a major and largely untried direction for future research.  相似文献

This paper describes how students are empowered in an action research project. The author argues that, given the opportunity, students are willing and have the ability to exercise their power to control their learning. In addition, the author contends that the more power students have in deciding what and how to learn, the harder they will work, the stronger their learning motivation will be, and the more they will gain in their learning. The experience gained in this project pointed to three important components of student empowerment efforts, i.e. empowerment through involvement, empowerment through partnership and empowerment through action research.  相似文献
