Fitness is an important component of health, and obese adolescents regularly have poor fitness. Unfortunately, few have assessed the impact of community-based lifestyle interventions on multiple components of fitness. The purpose of this study was to assess the impact of participation in a community-based intervention involving adolescents and parents on multiple components of fitness of obese adolescents. In a within-subject, waitlist controlled clinical trial with 12 months follow-up in Western Australia, participants (n = 56) completed multiple fitness measures at baseline, immediately prior to beginning an 8-week intervention and at 3, 6 and 12 months during a maintenance period. Performance on the shuttle walk was improved immediately post-intervention (increase of 42.8 m, 95% CI: 7.5, 78.2) and at 12 months post-intervention (increase of 44.6 m, 95% CI: 1.3, 87.8) compared with pre-intervention. Muscle performance of quadriceps and deltoids were improved post-intervention (increase of 1.1 (95% CI: 0.1, 2.1) kg · F and 1.0 (0.02, 2.1) kg · F, respectively) and all muscle performance measures were improved at 12 months following the intervention. There were no changes in waist circumference. A community-based lifestyle programme such as Curtin University’s Activity, Food and Attitudes Program (CAFAP) may be a viable strategy for improving fitness in overweight adolescents. 相似文献

This article is concerned with student engagement and understanding in large group teaching in Higher Education (HE). Specifically, it is concerned with the application of Multimedia Learning (MML) methods in Politics, History, International Relations, Sociology, Social Work, and Business and Economics teaching that privilege the use of images to complement text in lecture presentations. This ‘visual’ method, it is claimed in the literature, generates engagement and understanding better than text alone. This article develops, applies and empirically tests with students, MML methods across a range of Higher Education disciplines over three years. The research deploys Participatory Action Research (PAR) methods engaging students as active agents of investigation and change. It finds evidence to support the hypothesis that apposite images combined with reduced text increases students’ engagement and understanding with academic content, but that much formal research needs to expand on the range of demographics tested. 相似文献

Teacher competency frameworks comprise a number of competencies that enable a teacher to develop effective teaching practices. However, their conception, value, use and recognition vary widely. Equally, assessment and measurement of such competencies differ across contexts. More recently, a body of research has emerged which focuses the lens of teacher preparation on the inclusion of high leverage practices. The focus of this study is to report a synthesis of the literature pertaining to the ‘core competencies’ and ‘high leverage practices’ selected for inclusion in teacher preparation. A systematic review of the literature was conducted in order to synthesis available evidence. Results are presented in two sections; competency-based approaches; and high leverage practice approaches in teacher preparation. Findings are discussed from the perspective of epistemological and methodological questions emerging from the research and the implications for teacher preparation. 相似文献

This paper takes as a case study an undergraduate field class from a UK university to rural Uganda. It describes and evaluates the use of video diaries as a tool for investigating the process of transformative learning in the context of education for sustainability. The applicability of threshold concept theory to this learning is investigated. Results show the video diary technique to be much more successful in capturing the development of student learning than written diaries. Despite some practical difficulties, rich data were generated. Analysis demonstrated that learning met three of the five criteria for threshold concepts: the learning was transformative, integrative and troublesome. Further research could test whether the learning in this case study met the threshold concept criterion of irreversibility. Further elaboration of the theoretical relationship between threshold concepts, transformative learning and education for sustainability is also needed. It is concluded that the video diary method is potentially transferable to other educational research contexts and may be particularly suitable for researching learning in threshold spaces. 相似文献
