Whilst the measurement and quantification of vertical leg stiffness (Kvert) asymmetry is of important practical relevance to athletic performance, literature investigating bilateral asymmetry in Kvert is limited. Moreover, how the type of task used to assess Kvert may affect the expression of asymmetry has not been properly determined. Twelve healthy males performed three types of performance tasks on a dual force plate system to determine Kvert asymmetries; the tasks were (a) bilateral hopping, (b) bilateral drop jumping and (c) unilateral drop jumping. Across all the three methods, Kvert was significantly different between compliant and stiff limbs (P < 0.001) with a significant interaction effect between limb and method (P = 0.005). Differences in Kvert between compliant and stiff limbs were ?5.3% (P < 0.001), ?21.8% (P = 0.007) and ?15.1% (P < 0.001) for the bilateral hopping, bilateral drop jumping and unilateral drop jumping methods, respectively. All the three methods were able to detect significant differences between compliant and stiff limbs, and could be used as a diagnostic tool to assess Kvert asymmetry. Drop jumping tasks detected larger Kvert asymmetries than hopping, suggesting that asymmetries may be expressed to a greater extent in acyclic, maximal performance tasks. 相似文献

学校场域里的教育公正何以可能 总被引:1,自引:0,他引:1
教育公正是社会公正在教育中的体现,是促进教育和谐、社会和谐的重要力量。学校场域里存在诸多教育不公,对此进行揭示和批判是创造良好教育的前提性条件。学校场域里教育公正得以实现的可能方式在于促进教育中的制度公正、营造宽容的氛围、使教师转变为教育设计师角色和走向师生幸福关怀。 相似文献

分权理论认为政府职能的分立是防止专制的有效手段,但政府机构是多功能的,每个机构不可能只限于某种特定的职能,而且当工业文明发展到一定阶段,社会正义成为突出的价值观时,需要更为积极的自由观,政府之间的协调比控制更重要,此时,主要司法机关行使司法职能的原因并不是因为权力的制衡需要,乃是因为司法程序的独特性适应了这一职能.实质上,司法机关行使司法职能,既体现了职能的分立,亦是追求公正的选择,是"职能"(外力)与"程序"(内力)的合力作用.中国是个注意统一、协调、效率的国家,政党与人民代表大会都发挥了巨大的整合作用,政府机构不会因分立而陷入僵局.在这样的背景下,司法独立在程序上的技术改革受到鼓励,在职能上的独立就不可避免就有一定的难度. 相似文献

The aim of this study was to develop and validate an instrument of inclusive teachers’ competencies for teaching students with special educational needs in China. Data were obtained from a preliminary and large-scale investigation in Beijing. The primary analyses included exploratory factor analysis and confirmatory factor analysis. The findings indicated that Chinese inclusive teachers’ competency is underpinned by four factors: teaching and instruction; communication and cooperation; attitudes and beliefs; and reflection and development. The four-factor model was obtained with satisfactory reliability and validity. The validated questionnaire generated a theoretical understanding of inclusive education teachers’ competency in China. In addition, the findings of the study provided knowledge that will allow for the development of professional standards and teacher education programmes for inclusive education. 相似文献

Intervention at scale with the aim of improving student participation, engagement and outcomes in mathematics education is
a challenge for educational policy makers and reformers. This article argues that an iterative annual cycle of policy formulation,
implementation and evaluation enabled ongoing adjustments to the strategic focus, the professional development model and the
system infrastructure as the New Zealand Numeracy Development Project was taken to scale. The analysis draws on the project’s
evaluation data over a 6-year period to demonstrate how adjustments were made over time to the pedagogical tools and to the
professional development processes. The ongoing development of knowledge supported the management of strategic risks in taking
the project to scale: the ongoing appropriation of adequate levels of resourcing to support the school-based professional
development model and the availability of system-wide expertise for effective implementation. The analysis suggests that conceptualising
implementation as an interdependent and interrelated component of an iterative policy process and as an opportunity for knowledge
building ensured a continuing focus on student outcomes. The dynamic approach to the policy process appeared central to building
this intervention’s effectiveness and feasibility at scale. 相似文献
