Creating and disseminating knowledge through research and teaching has long been regarded as the hallmark of the modern university. However, new university business models have called into question the ‘bundling’ of teaching and research, and sustained research on the relationship between teaching and research has found little evidence of an insoluble connection between the two activities. In this article, we explore the relationship between teaching and research from the perspective of universities’ institutional discourse. We use corpus-assisted discourse analysis to examine the relationship between research and teaching as presented in two sets of institutional texts currently influential in UK Higher Education: Research Excellence Framework environment statements and Teaching Excellence Framework provider submissions (a total of 2143 documents and 12,492,071 words). Our findings show that, while universities emphasise the value of research to their teaching, they do not always emphasise (or sometimes even decry) the influence of teaching on their research. We empirically evidence that, according to what universities themselves write in institutional texts, teaching and research are not always in a mutually beneficial entanglement, but often rather a one-way relationship in which research expertise and institutional prestige are used to bolster claims of teaching excellence. This has implications for the communication of both the vision and the purpose of a university in regulatory exercises and wider policy, but also speaks to the broader idea and practice of being a university in the twenty-first century.  相似文献

Previous research has highlighted the positive effect that different warm-up protocols have on golf performance (e.g. Sorbie et al., 2016; Tilley & Macfarlane, 2012) with the design of warm-ups and programmes targeting and improving golf performance through the activation and development of specific muscle groups. This study aimed to examine the acute effects of two warm-up protocols on golf drive performance in comparison to a control condition. Using a randomised counterbalanced design over three testing sessions, twenty-three highly skilled golfers completed the control, dynamic and resistance-band warm-up conditions. Following each condition, a GC2 launch monitor was used to record ball velocity and other launch parameters of ten shots hit with the participants’ own driver. A repeated-measures ANOVA found significant increases in ball velocity (ηp2 = .217) between the control and both the dynamic and resistance-band warm-up conditions but no difference between these latter two, and a reduction in launch angle between control and dynamic conditions. The use of either a dynamic stretching or resistance-band warm-up can have acute benefits on ball velocity but golfers should liaise with a PGA Professional golf coach to effectively integrate this into their golf driving performance.  相似文献

ABSTRACT

This systematic review and meta-analysis aimed to determine differences in body compositionn between playing standard and age in male rugby union and rugby league athletes. The MOOSE (Meta-analysis of Observational Studies in Epidemiology) guidelines for design, implementation, and reporting were followed. Studies were required to be in male rugby union or league and have body composition as the primary or secondary outcome. Data was required to be presented separately for positional groups and body composition presented as whole-body. A systematic search was performed in PubMed, Cochrane Library, MEDLINE, SPORTDiscus, and CINHAHL via EBSCOhost. 57 studies were included for meta-analysis. Results highlighted significantly higher fat-free mass in senior elite than senior sub-elite or junior elite athletes for all RU and RL forwards. Small and non-significant differences were found in fat mass between rugby union playing standards and age categories. Rugby league senior elite forwards had less fat mass than junior elite forwards. Practitioners should prioritise training and nutritional strategies that maximise fat-free mass development, especially in junior elite cohorts.  相似文献

职业院校“情境——达标”式实训教学模式研究   总被引:6,自引:0,他引:6  
经济发展,需要职业教育规模发展,更需要其办学质量提高,而质量的评判需“社会化定位”。要克服职业院校“高分低能”、“高证低能”的现象,必须提高实训教学质量。以“三化”为主要内容的实训教学模式,抓住培养学生职业素质和能力的主线,通过在整个教学过程中创设职业情境的方式,达到真正提高实训教学质量的目的。  相似文献

我国新一轮高中课程标准修订的两个突出特色分别是以培养学生的学科核心素养作为课程目标,以学业质量标准来组织和优化评价方式.如何将学科核心素养和学业质量标准有机地融合在一起,是课程实施过程中迫切需要解决的问题之一.本文以高中化学学科为例,通过国际比较,从"内容设计""水平划分"和"特征分析"等方面探讨与素养导向学科学业质量标准研制有关的若干关键问题,以期在素养要素选择、规范表达和实践指导等方面为学科学业质量标准的设计和应用研究提供参考与借鉴.  相似文献

企业和高校之间存在人才需求端和人才供应端的联系,但两者性质、职能、价值目标、对社会变化反应速度等方面差别阻碍了产教融合进程。企业转型升级、高校人才培养急需产教携手,产教融合成为高等教育界和企业界的共同呼声。产教融合的实现基础是互信机制,即价值取向的互信认同、校企资源的互信共享、人才培养的互信联动,校企须遵循的价值取向应注重经济效益与社会效益的统一性、长期性、双向性和兼顾性,摒弃价值取向的短视性、单向性和片面性;充分认识校企拥有的物质资源和科技资源的互补性,构建资源的产教共享机制;积极挖掘双方人才培养中的合作潜能,企业认可及信任高校人才培养理念、方向、质量、规格,高校认同及信任企业人才培养不可替代的能力及作用,校企双方在人才培养方案修订与实施、理论教学与实践教学、工程能力培养与特殊技能培训三方面联动。  相似文献
