The relationships between team performance indicators and match outcome have been examined in many team sports, however are limited in Australian Rules football. Using data from the 2013 and 2014 Australian Football League (AFL) regular seasons, this study assessed the ability of commonly reported discrete team performance indicators presented in their relative form (standardised against their opposition for a given match) to explain match outcome (Win/Loss). Logistic regression and decision tree (chi-squared automatic interaction detection (CHAID)) analyses both revealed relative differences between opposing teams for “kicks” and “goal conversion” as the most influential in explaining match outcome, with two models achieving 88.3% and 89.8% classification accuracies, respectively. Models incorporating a smaller performance indicator set displayed a slightly reduced ability to explain match outcome (81.0% and 81.5% for logistic regression and CHAID, respectively). However, both were fit to 2014 data with reduced error in comparison to the full models. Despite performance similarities across the two analysis approaches, the CHAID model revealed multiple winning performance indicator profiles, thereby increasing its comparative feasibility for use in the field. Coaches and analysts may find these results useful in informing strategy and game plan development in Australian Rules football, with the development of team-specific models recommended in future. 相似文献

The purpose of this study is to demonstrate that performance assessment increases educational value in teachinglearning activities
using a quasi-experimental research design. In this research, the three measurement criteria of educational value are suggested
as ‘improvement & advancement,’ ‘sincerity & enthusiasm,’ and ‘individuality & wholeness.’ A pre-test was administered to
4 classes (156 students) in 7th grade. Classes were divided into an experimental group (2 classes, 79 students) and a control
group (2 classes, 77 students), according to the pre-test results. Only the experimental group was involved in the performance
assessment for 9 weeks. The results of this study show that performance assessment has a positive effect on the educational
value of teaching-learning activities in schools. 相似文献

This study aimed to investigate if moderate to vigorous physical activity (MVPA) and aerobic fitness are associated with cardiovascular risk factors in HIV+ children and adolescents. Sixty-five children and adolescents (8 to 15 years) provided minutes of MVPA measured by accelerometers and peak oxygen uptake (peak VO2) by breath-by-breath respiratory exchange. Cardiovascular risk factors were characterized by body fat, blood pressure, total cholesterol, HDL-c, LDL-c, triglycerides, glucose, insulin, C-reactive protein (CRP), interleukin (IL)-6, tumor necrosis factor-alpha (TNF-α) and carotid intima-media thickness. Results indicated that higher MVPA was associated with lower values of total (β = ?3.566) and trunk body fat (β = ?3.495), total cholesterol (β = ?0.112) and LDL-c (β = ?0.830). Likewise, higher peak VO2 was associated with lower total (β = ?0.629) and trunk body fat values (β = ?0.592) and levels of CRP (β = ?0.059). The physically active participants had lower total cholesterol (?24.4 mg.dL?1) and LDL-c (?20.1 mg.dL?1) compared to participants judged to be insufficiently active. Moreover, participants with satisfactory peak VO? showed lower total (?4.1%) and trunk (?4.3%) body fat, CRP (?2.3 mg.L?1), IL-6 (?2.4 pg.mL?1) and TNF-α (?1.0 pg.mL?1) compared to low peak VO2 peers. High levels of MVPA and aerobic fitness may prevent developing of cardiovascular risk factors in children and adolescents HIV+. 相似文献

Representative learning design provides a framework for the extent to which practice simulates key elements of a performance setting. Improving both the measurement and analysis of representative learning design would allow for the refinement of sports training environments that seek to replicate competition conditions and provide additional context to the evaluation of athlete performance. Using rule induction, this study aimed to develop working models for the determination of high frequency, representative events in Australian Rules football kicking. A sample of 9005 kicks from the 2015 Australian Football League season were categorised and analysed according to the following constraints: type of pressure, kick distance, possession source, time in possession, velocity and kick target. The Apriori algorithm was used to develop two models. The first consisted of 10 rules containing the most commonly occurring constraint sets occurring during the kick in AF, with support values ranging from 0.15 to 0.22. None of the rules contained more than three constraints and confidence values ranged from 0.63 to 0.84. The second model considered ineffective and effective kick outcomes and displayed 70% classification accuracy. This research provides a measurement approach to determine the degree of representativeness of sports practice and is directly applicable to various team sports. 相似文献

From the contextual perspective, researchers argue that the relevance and weight of motivational variables of students' functioning vary depending on different dimensions related to individual, cultural or situational characteristics. The first objective of this study examined this contention by comparing self-perceptions of competence, learning goals and judgments of usefulness of school subjects as motivational determinants of high school students' commitment and achievement according to their assignment to their learning abilities. The second objective was to compare how these variables related to academic commitment and achievement according to the type of student and two school subjects. Two-hundred-and-twenty-six high school students from a same school participated sixty-one were learning disabled students, 60 were high achievers and 105 were average students. Findings suggest that the relevance of the motivational variables did not vary much across either the type of student or the school subjects. They also support Bandura's view about the primary role of self-perceptions of competence in students' academic commitment and achievement. 相似文献

The research described in this article aimed to explore and examine the dominant ‘assessment’ and ‘participation’ stories of upper‐primary pupils with long‐standing and marked literacy learning needs, their views on how their level of participation in the assessment and remediation of their additional needs might be increased and also how they perceive themselves as literacy learners. This qualitative small‐scale study adopted a case study approach and utilised creative methodologies in the context of focus groups to investigate sensitively the views and experiences of Key Stage 2 pupils with additional needs in literacy. The findings discussed here are based on the outcomes from the four Northern Irish schools that participated in the original cross‐border (Northern Ireland/Republic of Ireland) study. Findings are discussed in the context of strategies for promoting holistic and empowering pathways for learners with additional needs in literacy. 相似文献

This article presents a horizontal perspective on the dynamics of governance sites currently active for the European of Knowledge and places the Bologna process in this wider European level context. It introduces two dynamics of change in political organisation: a) institutional differentiation and specialisation and b) the interaction between institutional spheres and sectors. Signs of sectoral differentiation are identified in the history of European integration that is relevant to the Europe of Knowledge. The argument is that the nature and sequence of the differentiation process are key to understand current governance processes. It is illustrated by showing how a horizontal dynamics has been played out in the case of the EU's Lisbon strategy and in particular the cooperation taking place in the framework of the EU's “Education and Training 2010” work programme. The analysis shows how the Bologna process, although perpetuated as a sector internal governance site, has co-evolved and interacted with this strategy, partly as an object of emulation and source of support and partly as a competing governance site. A horizontal dynamics of change is also evident in the larger Lisbon strategy as it lifted research and higher education policy to the centre of the European integration project. It resulted in the development of several governance sites with different foci targeting European higher education. A more prominent place on the political agenda came together with demands that research and education should be integrated with the overall political and economic objectives of the EU. 相似文献

This study examines and evaluates special provision for pupils with dyslexia in three different settings: reading schools, reading units and mainstream support. The research focused on the teaching and learning context for pupils with dyslexia, the support teacher, the mainstream teacher and the experience of the student. The main participants were teachers and tutors supporting pupils with dyslexia, and the parents of these children. Survey methods included questionnaires, focus group discussions, interviews and quantitative data on pupils' reading attainment. In addition, a total of six schools, two representing each model of support, were selected as case studies. This article reports part of a larger survey, which evaluated the effectiveness of three models of special provision for children with dyslexia in primary school. The study shows that there are academic and social benefits for the child with dyslexia who is enrolled in a special setting. However, placement in a reading school or reading unit per se does not guarantee that a child will ‘catch up’ with his or her peers. The findings reported a similarity in the methods and practices teachers use in both mainstream and special settings. The discussion suggests that if teachers are to ‘catch them before they fall’ there are serious questions that must be asked about how we are teaching basic literacy skills. The findings suggest an urgent need for a more balanced approach to teaching reading and writing. 相似文献
