The purpose of this study was to assess the effect of periodized resistance training on accelerative sprint performance. Sixteen physically active men participated in a randomized controlled study. An experimental group (n = 10) completed an 8-week periodized resistance training intervention, while a control group (n = 6) did not train. Pre- and post-training measures of 20-m straight-line sprint time, including a 10-m split, maximum strength, and explosive strength, were recorded. Flight time, stance time, stride length, and stride frequency were quantified from digitized video recordings of the first three strides of the 20-m sprint. Resistance training resulted in significant increases in maximum strength (parallel back squat: 19%) and explosive strength (6-10%). However, both groups increased 0-10 m sprint times (experimental group = 6%; control group = 3%) while 10-20m times were reduced (experimental group = 7%; control group = 4%), highlighting the mechanical differences between the distinct sprint phases. The change during the 0-10m interval was accompanied by a reduction in stride frequency during the first three strides. Strength coaches should be aware that the potential benefits of increased muscular strength during short sprints are likely to be affected by mechanical specificity and that improvements in sprinting performance may not occur immediately after a period of resistance training.  相似文献

Examples of Good Practice when Dealing with Bullying in a Further/Higher Education College     

Gavin Hughes 《Pastoral Care in Education》2001,19(3):10-13

This qualitative study, conducted via interviews, focuses on the strategies used by tutors and support staff in dealing with bullying in an FE/HE college. This area is under researched and yet studies have shown that 10 per cent of students in FE experience bullying (McDougall, 1999). It was found that bullying was being dealt with effectively using a range of approaches. The examples of good practice found in this study correspond with the more extensive work into primary and secondary schools by Byrne (1994), Tattum and Herbert (1993) and Sharp and Smith (1993). All respondents treated the issue seriously and relationships built up between tutors/support staff and the students were the crucial factor.  相似文献

Self-regulation of assessment beliefs and attitudes: a review of the Students’ Conceptions of Assessment inventory     

Gavin T. L. Brown 《教育心理学》2011,31(6):731-748

How students understand, feel about and respond to assessment might contribute significantly to learning behaviour and academic achievement. This paper reviews studies that have used a relatively new self-reported survey questionnaire (Students’ Conceptions of Assessment – SCoA) about student perceptions and understandings of assessment. Confirmatory factor analyses and structural equation modelling results have shown, consistent with self-regulation theory, that the SCoA inventory has meaningful relations with academic performance among New Zealand high school students. Further, German, Hong Kong, American, and New Zealand studies have shown that the SCoA has relations to motivational constructs (e.g. effort, learning strategies, interest, self-efficacy and anxiety) that are also consistent with self-regulation. The SCoA inventory extends our understanding of how student conceptions of assessment are an integral part of self-regulation and provide a warrant for use in research studies investigating test-taker responses to assessment practices and innovations at both university and high school levels.  相似文献   

Internal and external focus of attention in a novice form sport     

Lawrence GR  Gottwald VM  Hardy J  Khan MA 《Research quarterly for exercise and sport》2011,82(3):431-441

In the current experiment, we examined optimal focus for novices during a movement sequence in which performance was measured on accurate movement form/technique. A novel gymnastics routine was practiced under either an internal skill-relevant, internal skill-irrelevant, external, or no attention focus. Retention and transfer tests were then completed. During acquisition, adopting an internal irrelevant focus significantly improved performance, whereas an external focus degraded performance. There were no significant group differences in the retention and transfer tests. This suggests that learning of movement form/technique did not benefit from a specific focus of attention. The results are interpreted via an attentional capacity viewpoint and the notion that form tasks do not always contain obvious movement effects central to common coding and the constrained action hypothesis.  相似文献   

Understanding outcome-based education changes in teacher education: evaluation of a new instrument with preliminary findings     

Christopher Deneen  Gavin T.L. Brown  Trevor G. Bond  Ronnie Shroff 《Asia-Pacific Journal of Teacher Education》2013,41(4):441-456

Outcome-based education (OBE) is a current initiative in Hong Kong universities, with widespread backing by governments and standards bodies. However, study of students’ perceptions of OBE and validation of understanding these perceptions are lacking. This paper reports on the validation of an OBE-specific instrument and resulting preliminary findings. Instrument responses (n = 89) were analysed using Rasch and exploratory/confirmatory factor analyses. Both approaches identified two dimensions (i.e. evaluation and comparison). Challenges and modifications to the instrument items and their relationships to constructs are discussed. Preliminary findings suggest students did not perceive significant differences between OBE and traditionally organised courses. Lack of explicit discussion of OBE with the students may have denied students the ability to make fully informed evaluations of OBE innovations. Implications for instrument validation and evaluation of initiatives in an OBE context are discussed as is the broader issue of transparency in teacher education curriculum design and implementation.  相似文献   

Factors influencing early adolescents’ mathematics achievement: High-quality teaching rather than relationships     

Sandra Winheller  John A. Hattie  Gavin T. L. Brown 《Learning Environments Research》2013,16(1):49-69

This study used data from the Assessment Tools for Teaching and Learning project, which involved data on the academic performance of more than 90,000 New Zealand students in six subjects (i.e. reading, writing and mathematics in two languages). Two sub-samples of this dataset were included for detailed re-analysis to test the general applicability of the Australian model of Quality of School Life (Ainley et al. 1986) in the New Zealand context. The first sample comprised 336 year 8 students from elementary schools and the second sample consisted of 272 year 10 students from high schools. Furthermore, two structural equation models were developed and tested, expressing relationships between students’ quality of school life perceptions, students’ attitudes to mathematics, and their effects on mathematics achievement. The quality of school life questionnaires scales [Ainley and Bourke, in Res Pap Educ 7(2):107–128, 1992] were used as indicators of students’ perceptions regarding learning, teachers and peer relationships. The model proposed that perceived quality of school life would affect students’ attitudes of liking and confidence in mathematics, which would in turn affect their academic performance. After controlling for other variables in the model, students’ perception about their self-efficacy to learn mathematics was more directly related to outcomes than to perceptions of teacher quality or peer involvement. Data analyses revealed no apparent relationships of these factors to mathematics achievement. Moreover, results for both samples led to the conclusion that the perceived quality of learning is connected with ‘confidence in’ and ‘liking mathematics’, which in turn predict students’ mathematics achievement.  相似文献
