Turnout, or external rotation (ER) of the lower extremities, is essential in ballet. The purpose of this study was to utilise physical examination and a biomechanical method for obtaining functional kinematic data using hip and knee joint centres to identify the relative turnout contributions from hip rotation, femoral anteversion, knee rotation, tibial torsion, and other sources. Ten female dancers received a lower extremity alignment assessment, including passive hip rotation, femoral anteversion, tibial torsion, weightbearing foot alignment, and Beighton hypermobility score. Next, turnout was assessed using plantar pressure plots and three-dimensional motion analysis; participants performed turnout to ballet first position on both a plantar pressure mat and friction-reducing discs. A retro-reflective functional marker motion capture system mapped the lower extremities and hip and knee joint centres. Mean total turnout was 129±15.7° via plantar pressure plots and 135±17.8° via kinematics. Bilateral hip ER during turnout was 49±10.2° (36% of total turnout). Bilateral knee ER during turnout was 41±5.9° (32% of total turnout). Hip ER contribution to total turnout measured kinematically was less than expected compared to other studies, where hip ER was determined without functional kinematic data. Knee ER contributed substantially more turnout than expected or previously reported. This analysis method allows precise assessment of turnout contributors. 相似文献

Students’ transition to academia comes with a number of challenges which, if inadequately addressed, may negatively affect their academic performance and psychological well‐being. Hence, the question of support becomes critical and has been reflected in the variety of practical measures to provide support with learning and facilitate newcomers’ integration into higher education. However, while forms of institutional aid have increased and diversified in recent years, the kind of support the students actually need and prefer to use – from the pool of available resources – remains insufficiently understood in current research. To address this gap, this paper advocates a social network approach to first‐year students’ experiences of coping with academic life and suggests an agenda for further investigation, which would contrast support ‘from above’ and support ‘from below.’ 相似文献

The problems of shifting from norm-referenced assessment to criterion-referenced assessment have been identified by several scholars in recent years. These important critiques touch on a number of areas, but neglect a key question about how assessors learn to accomplish what Shay calls a ‘socially situated interpretive act'. Research that does exist tends to focus on salaried, full-time academics. This overlooks the heterogeneity of the academic labour force in higher education and the substantial contribution made by contract (hourly-paid) lecturers, particularly in applied disciplines such as Business and Management. This study explores how nine newcomers to a UK Business School – including salaried and contract staff – attempt to understand local assessment practice. We use a situated learning lens to analyse their diary entries and interviews about their experiences of learning to mark. Drawing on scholars such as Sadler, we examine the suggestion that exemplars are important for newcomers coming to understand local assessment practice. We argue for the fundamental importance of dialogue about exemplars and other aspects of practice, both to develop inter-subject understandings of assessment ‘anchor points' and also to foster among newcomers (and especially contract lecturers) a greater sense of participating in, and being valued by, the local assessment community. 相似文献

From copying to learning: using exemplars to engage students with assessment criteria and feedback 总被引：3，自引：2，他引：1
Feedback is central to pedagogic theory, and if feedback is to be effective, students need to engage with it and apply it at some point in the future. However, student dissatisfaction with feedback – as evidenced in the National Student Survey – suggests that there are problems which limit student engagement with feedback, such as their perception that much of their feedback is irrelevant to future assignments. This article reports on a study which sought to enhance engagement by giving students exemplar assignments annotated with feedback before submission of their final assignments. This was done by providing an online facility where students could view exemplars and post comments or questions to tutors and peers on a discussion board. The exemplar facility was highly valued by students, although there were no quantitative effects such as an increase in students’ assignment marks when compared with the previous cohort. The article reflects on possible reasons for this result and discusses ways to improve the exemplar facility, for example by facilitating dialogue between tutors and students. The article concludes with lessons learned about how to construct exemplars, and considers how exemplars might also be used within marking teams to improve consistency of marking. 相似文献

Achievement differences shown by teaching clerical skills through use of computer-assisted instruction (CAI) and traditional self-paced instruction were investigated. Differentials in correlations of achievement with aptitude and learning style measures for students taught by the two methods were determined. A randomized pretest-posttest design with analysis of covariance was used to compare achievement differences. Group differences in relationships between learning-related variables and achievement were compared through Fisher r to z transformations. The CAI group achieved significantly higher than did the traditional group. Arithmetic aptitude and learning styles associated with sociability traits correlated higher with achievement in the CAI group than in the traditional group. Different aptitude-learning style patterns were associated with higher achievement in the two groups. 相似文献

Matrix metalloproteinase-3 (MMP3) is a mediator of matrix remodelling and a proposed susceptibility locus in the genetic profile of musculoskeletal soft tissue injuries. Therefore, this study aimed to validate the MMP3 gene as a risk marker for these injuries by conducting a case control genetic association study in two independent samples groups. Three previously investigated MMP3 variants (rs679620, rs591058 and rs650108) in addition to the functional promoter variant (rs3025058) were genotyped in 195 Australian control participants and 79 Australian individuals with chronic Achilles tendinopathy. Similarly, 234 South African individuals with acute anterior cruciate ligament ruptures and 232 matched control participants were also analysed. Based on high linkage with the previously associated MMP3 variant rs679620, rs3025058 was inferred and found to be associated with increased risk for Achilles tendinopathy within the South African group (P = 0.012; OR: 2.88; 95% CI: 1.4 to 6.1). Lastly, the 6A-G-C-G haplotype, constructed from the investigated variants, was significantly associated with reduced risk for Achilles tendinopathy (29% CON vs. 20% TEN, P = 0.037) in the Australian group. In conclusion, a signal surrounding MMP3 is apparent with respect to Achilles tendinopathy. However, whether the investigated variants are contributing to injury susceptibility or whether they are merely linked to the risk conferring variants mapping elsewhere within the MMP gene cluster on chromosome 11, still requires refining. 相似文献
