论体育运动中情绪过程的功能意义

1　前言让我先讲个小故事吧。有一位年青的网球运动员 ,他对自己能够闯入决赛感到非常兴奋 ,这在赛前他是想也没有想到过的。进入中心赛场后 ,听到观众如潮的掌声 ,一种骄傲的感觉油然而生 ,但同时他也感到自己心跳强烈 ,手心出汗 ,他不禁问自己 :我是不是能够不负众望 ?是不是能和两周前打得一样好呢 ?心中涌出一丝害怕失败的感觉。在赛前适应场地时 ,他在场内来回跑动、击球 ,注意力开始集中于球赛 ,紧张的感觉逐渐减轻 ,在场上的感觉也越来越好。比赛开始了 ,……比赛中 ,他时而为了一个幸运球而兴奋 ;时而为了自己愚蠢的回球后而懊悔不…     

The effect of limb dominance on lower limb functional performance – a systematic review

Lower limb dominance (or lateral preference) could potentially effect functional performance. Clinicians are often asked to make judgements as to when a patient has sufficiently “recovered” from an injury, typically using strength and dynamic performance outcome measures. The primary purpose of this study was to systematically review the literature in relation to limb dominance within active adult populations and discuss some limitations to current methods and relate this to current clinical practice. A search of MEDLINE and CINAHL and EMBASE databases and reference lists of those articles identified was performed. Eleven articles were selected for meta-analysis. There was no statistical effect of limb dominance for any of the functional tests: isokinetic quadriceps and hamstring tests, hamstring:quadriceps ratios, single-leg hop for distance, single-leg vertical jump and vertical ground reaction force following a single-leg vertical jump. Pooled symmetry values varied from 94.6% to 99.6% across the tests, above the clinically accepted benchmark of 90% used in clinical practice. Although the results of this study must be used with discretion, asymmetries in the tasks described in this analysis should be viewed as undesirable and remedied accordingly. Further research is needed to quantify asymmetries, particularly in relation to sport-specific contexts.     

The influence of self-efficacy and past behaviour on the physical activity intentions of young people

The aim of the present study was to assess the influence of self-efficacy and past behaviour on young people's physical activity intentions using an augmented version of Ajzen's Theory of Planned Behaviour. We hypothesized that self-efficacy would exhibit discriminant validity with perceived behavioural control and explain unique variance in young people's intentions to participate in physical activity. We also expected that past physical activity behaviour would attenuate the influence of attitude, subjective norms, perceived behavioural control and self-efficacy on intention. The sample comprised 1,152 young people aged 13.5 +/- 0.6 years (mean +/- s) who completed inventories assessing their physical activity intentions, attitudes, subjective norms, perceived behavioural control, self-efficacy and past physical activity behaviour. A confirmatory factor analysis demonstrated that the constructs of the Theory of Planned Behaviour achieved discriminant validity. Furthermore, the measures of attitudes, subjective norms, perceived behavioural control and self-efficacy were significantly related to their respective belief-based measures, supporting the concurrent validity of the measures of the Theory of Planned Behaviour. A non-standard structural equation model demonstrated that attitude and self-efficacy were strong predictors of physical activity intention, but perceived behavioural control and subjective norms were not. Self-efficacy attenuated the influence of attitudes and perceived behavioural control on intention. Past behaviour predicted intention directly and indirectly through self-efficacy and attitude. The present findings demonstrate that young people with positive attitudes and high self-efficacy are more likely to form intentions to participate in physical activity. Furthermore, controlling for past physical activity behaviour revealed that the unique effects of self-efficacy and attitudes on young people's physical activity intentions were unaltered.     

Teaching Hypertext Composition

Composing hypertext documents can be an enriching path into the world of technical communication. In learning to produce hypertext, students are introduced to an important form of written composition that encompasses not only text generation, but also visual communication and information architecture. In this article, I provide a rationale for teaching hypertext composition and then some specific curricular suggestions in two parts, one for teaching beginners, and one for teaching more advanced students.     

Organization of schooling: Achieving access and quality through inclusion

Conclusion Michael Fullan, Dean of Education at the University of Toronto and an acknowledged expert on educational change, reform and improvement, has noted that reform in special education ‘represents just about all the issues involved in bringing about educational reform.’ complexity and leadership are particularly difficult challenges. Fullan has noted that, ‘the solutions to inclusion are not easily achieved. It is complex both in the nature and degree of change required to identify and implement solutions that work. Given what change requires—persistence, coordination, follow-up, conflict resolution, and the like—leadership at all levels is required...’ (Fullan, 1991b). Organizational support for inclusive education must be in place at the provincial/state level, the regional/school district level, and at the school level. These structures, programmes and policies must deliver the support needed by classroom teachers and their students. We have set out specific ways that this can be done, consistent with an inclusive policy framework. The commitment to equity, as well as access and quality, requires continuing development by building on these approaches. In so doing, we can achieve better results for students with special needs while simultaneously creating more effective schools for all students. A former teacher and school principal, Gordon Porter is now director of student services for the public schools in Woodstock, New Brunswick. A well-known advocate for integrated education, he has been instrumental in developing inclusionary programmes for all students in the schools in the Woodstock area, and throughout the province of New Brunswick. Dr. Porter has conducted training in many parts of Canada as well as the United States. He is currently vice-chair of the Committee on Integrated Education of the International League of Societies for the Mentally Handicapped.     

DEVELOPING PARENT‐PROFESSIONAL PARTNERSHIPS IN A POSTSECONDARY EDUCATION PROGRAM FOR STUDENTS WITH DISABILITIES

Opportunities are increasing for students with intellectual and/or developmental disabilities to attend postsecondary education programs located at college campuses around the nation. Students who attend postsecondary education programs experience numerous positive outcomes, including independent living skills and expanded social networks. However, although parent‐professional partnerships could significantly enhance long‐term outcomes such as competitive employment and independent living, there is a paucity of information about the nature of these partnerships in postsecondary settings. The purpose of this expository article is to describe how staff from a midwestern postsecondary education program facilitate parent‐professional partnerships through parent involvement and support.     

Threats to student evaluative judgement and their management

ABSTRACT

Students’ capacity for making evaluative judgements of their own work is widely acknowledged as central to their learning within programmes as well as being vital to their subsequent professional practice. In higher education literature, the act of evaluative judgement is usually portrayed as a process of deliberative, analytical reasoning requiring student agency and objectivity, typically scaffolded by points of reference such as explicit criteria, rubrics or exemplars. This article challenges this common portrayal of judgement by drawing attention to research from outside higher education on the role of unconscious factors in judgement and decision-making. Drawing from the field of heuristics and bias studies, the article outlines six unconscious factors that have the potential to distort students’ analytical judgement of their work. A recent challenge to the heuristics and bias approach that radically repositions the place of reasoning in judgement is also considered. Since these unconscious factors have received scant attention in higher education literature, the purpose of this article is to draw attention to them, to identify the challenges they pose to current understandings of evaluative judgement, and to outline their implications for enhancing assessment practice.     

Techne and Technical Communication: Toward a Dialogue

The classical Greek discourse on techne has much to offer technical communication teachers concerned about the relationship between theory and practice, but this potential has not yet been realized. Plato's and Aristotle's discussions about the relationship between techne and rhetoric, for example, encompass questions about the rhetorical goals of the speakedwriter and about the role of theory in teaching rhetorical art that are of continuing relevance to the modern discourse on technical communication. The aim of this article is to identify several points upon which a fruitful dialogue between ancient and modern discourses can begin. First, I supply some background on how the term techne was used up through the fourth century BCE. Then I discuss how the modern discourse on technical communication (including material from popular textbooks) both converges with and departs from Plato's and Aristotle's statements on the relationship between techne and rhetoric. Finally, I point out areas for further discussion as teachers of technical communication continue to reflect upon and refine their pedagogies.
