With the aim of determining both the acute and the chronic effects of textured insoles on the ankle discrimination and performance ability of dancers, 60 ballet dancers from the Australian Ballet School, aged 14–19 years, were divided into three groups (two intervention groups and a control group), age- and level-matched. In the first 5 weeks (weeks 1 to 5), the first intervention group (GRP1) was asked to wear textured insoles in their ballet shoes and the second intervention group (GRP2) was not given textured insoles to wear. In the next 5 weeks (weeks 6 to 10), GRP2 was asked to wear the same type of textured insoles and GRP1 did not wear the textured insoles. The control group (CTRL) did not wear textured insoles during the whole 10 weeks. All participants were tested preintervention, after 5 weeks and after 10 weeks for ankle discrimination score (AUC scores). Dance performance was assessed by 5–7 dance teachers. Pre-to-post change in AUC scores was significantly greater for the groups wearing insoles than for the controls (P = .046) and the size of pre-to-post changes did not differ between the two intervention groups (P = .834). Significant correlation was found between ankle discrimination score and performance scores, using the textured insoles (r = .412; P = .024). In conclusion, the stimulation to the proprioceptive system arising from textured insoles worn for five weeks was sufficient to improve the proprioceptive ability and performance ability of ballet dancers.  相似文献   

Elite coaching and the technocratic engineer: thanking the boys at Microsoft!     

Shaun Williams  Andrew Manley 《Sport, Education and Society》2016,21(6):828-850

The primary purpose of this article is to provide an in-depth understanding of the manner in which surveillance technologies have become readily appropriated and utilised by elite Rugby Union coaches. It is conceded that positions adopted by populist writings commonly categorise the act of coaching as an educational activity that harnesses holistic intentions. Through reflecting upon semi-structured interviews with players located at an Aviva Premiership Rugby Union Club, we provide insight into an elite sporting institution that more accurately depicts coaching as a technocratic activity. The resultant analysis is critical in its review of surveillance mechanisms embedded in institutional practice, extending to the sports coaching setting, which explicate sinister rather than pastoral motives to enforce a disciplinary power that enhances the quantification of athletic performance. The article concludes by emphasising the impact of such practices upon establishing a sense of trust and the construction of self autonomous to the sporting domain. We argue that the emerging and steadfast acceptance of technology in the elite coaching environment is threatening to circumvent the learning potential of players by merely viewing them as functionaries. In adopting this position, we tentatively suggest that future research seeking to inform the practice of coaching and coach education should continue to pursue this critical dialogue to question whether, and to what extent, an overreliance on technology is becoming perceived as the ‘gold standard’ of professional practice amongst the coaching fraternity.  相似文献

Talent identification and selection in elite youth football: An Australian context     

Donna O'Connor  Paul Larkin  A. Mark Williams 《European Journal of Sport Science》2016,16(7):837-844

We identified the perceptual–cognitive skills and player history variables that differentiate players selected or not selected into an elite youth football (i.e. soccer) programme in Australia. A sample of elite youth male football players (n?=?127) completed an adapted participation history questionnaire and video-based assessments of perceptual–cognitive skills. Following data collection, 22 of these players were offered a full-time scholarship for enrolment at an elite player residential programme. Participants selected for the scholarship programme recorded superior performance on the combined perceptual–cognitive skills tests compared to the non-selected group. There were no significant between group differences on the player history variables. Stepwise discriminant function analysis identified four predictor variables that resulted in the best categorization of selected and non-selected players (i.e. recent match-play performance, region, number of other sports participated, combined perceptual–cognitive performance). The effectiveness of the discriminant function is reflected by 93.7% of players being correctly classified, with the four variables accounting for 57.6% of the variance. Our discriminating model for selection may provide a greater understanding of the factors that influence elite youth talent selection and identification.  相似文献

How do instructional designers evaluate? A qualitative study of evaluation in practice     

David D. Williams  Joseph B. South  Stephen C. Yanchar  Brent G. Wilson  Stephanie Allen 《Educational technology research and development : ETR & D》2011,59(6):885-907

This study employed a qualitative research design to investigate how instructional designers use evaluation in everyday design practice. While past research has examined how designers spend their time, how they generally make decisions, and expert-novice differences, little attention has been paid to use of context, input, process, or product evaluation, from the perspective of practicing designers. Based on interviews of practitioners, our findings included ten themes regarding how designers use evaluation to improve their products. While these results substantiate to some degree the claim that practitioners believe clients will not pay for formal evaluations, they also suggest that practitioners use evaluation in important but less formal ways. Other conclusions regarding the role of evaluation in design are provided and future directions for training and research are discussed.  相似文献   

Instructional design and project management: complementary or divergent?     

Shahron Williams van Rooij 《Educational technology research and development : ETR & D》2011,59(1):139-158

This paper reports the results of a study to identify the extent to which organizations that develop educational/training products are committed to project management, as measured by their project management implementation maturity, as a methodology that is separate and distinct from the processes of instructional design. A Web survey was conducted among 103 public and private sector organizations worldwide that develop educational/training products. Results show no significant difference by project management maturity level in the roles of instructional designer and project manager, although there is some relationship between maturity level and how organizations perceive the skills/competencies of project managers versus those of instructional designers. Further, organizational decision-makers have very specific expectations about the formal education and training of educational/training product development project leaders. The findings should be of value to institutions of higher education in evaluating programs that prepare students for careers in instructional design.  相似文献

Empathetic-Reflective-Dialogical Restorying for decolonisation: an emancipatory teaching-learning strategy for Religion Education     

Janet Jarvis 《British Journal of Religious Education》2021,43(1):68-79

ABSTRACT

This article argues for the inclusion of Empathetic-Reflective-Dialogical Restorying as a teaching-learning strategy for Religion Education. This strategy, employed in three small-scale research projects in a South African Higher Education Institution, addresses decolonisation of the Religion Education curriculum in the following ways: changing how teaching-learning takes place; transdisciplinary engagement; empowering students as agents of their own learning; depatriarchisation; and dispelling the myth of African inferiority. Both self-dialogue and self-narrative were used to create open space stories when approaching content that is relevant to the lived experience of gender (in)equality and patriarchy. Engaging in a safe space in Communities in Conversation, Communities in Dialogue, and Communities for Transformation, students troubled entrenched beliefs and worldviews and co-constructed (restoried) understandings. They expressed the view that this emancipatory teaching-learning strategy has the potential to facilitate classroom praxis that is both reflective and reflexive. This can be transformative for the greater society.  相似文献
