ABSTRACT

We compared cardiometabolic demand and post-exercise enjoyment between continuous walking (CW) and time- and intensity-matched interval walking (IW) in insufficiently active adults. Sixteen individuals (13 females and three males, age 25.3 ± 11.1 years) completed one CW and one IW session lasting 30 min in a randomised-counterbalanced design. For CW, participants walked at a mean intensity of 65–70% predicted maximum heart rate (HR_max). For IW, participants alternated between 3 min at 80% HR_max and 2 min at 50% HR_max. Expired gas was measured throughout each protocol. Participants rated post-exercise enjoyment following each protocol. Mean HR and V˙O₂ showed small positive differences in IW vs. CW (2, 95%CL 0, 4 beat.min^?1; d = 0.23, 95%CL 0.06, 0.41 and 1.4, 95%CL 1.2 ml.kg^?1.min^?1, d = 0.36, 95%CL 0.05, 0.65, respectively). There was a medium positive difference in overall kcal expenditure in IW vs. CW (25, 95%CL 7 kcal, d = 0.58, 95%CL 0.33, 0.82). Post-exercise enjoyment was moderately greater following IW vs. CW (9.1, 95%CL 1.4, 16.8 AU, d = 0.62, 95%CL 0.06, 0.90), with 75% of participants reporting IW as more enjoyable. Interval walking elicits meaningfully greater energy expenditure and is more enjoyable than CW in insufficiently active, healthy adults.  相似文献   

Bundled or unbundled? A multi-text corpus-assisted discourse analysis of the relationship between teaching and research in UK universities     

Adam Matthews  Ben Kotzee 《British Educational Research Journal》2022,48(3):578-597

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   

学分银行理念下开放教育综合实践教学改革初探     

谢妙忻  吴晓辉 《继续教育研究》2021,(1):33-36

随着信息技术日新月异、行业形态不断改变、新业态源源不断出现,社会对人才培养也随之提出更高的要求。在开放教育中,综合实践教学虽然处在战略性地位,但是在学习者专业技能培养中,往往只偏重于理论教育,实践技能教育存在流于形式、学习内容陈旧、实践资源缺失等问题,导致人才培养与实际岗位需求脱节。为了适应开放教育的发展趋势,结合当前开放教育综合实践教学中存在的实施不足、教学方式单一和实践基地弱化等问题,提出开放教育综合实践教学模式应以“学分银行”理念为基础,对综合实践教学进行行之有效的改革,以提升其教学质量和有效性。  相似文献   

'She just got me’: supporting care experienced young people negotiating relationships and identities at school     

Gale Macleod  Robin Dallas-Childs  Colin Brough  Martin Toye 《Journal of Research in Special Educational Needs》2021,21(Z1):25-35

In this article we examine the complex relationship between care experience, mental health and exclusion from school and how young people (YP) negotiate these different experiences and identities. The study is a secondary analysis, informed by symbolic interactionist theory, of interviews conducted with 19 care experienced YP in Scotland. Not all of the YP were excluded and not all had a formal mental health diagnosis, as such our study design allows interrogation of the contexts and relationships which not only facilitate but also disrupt pathways to exclusion. It also allows reconsideration of assumptions of vulnerability which are often applied to care experienced YP. Our findings suggest that these YP are moving beyond ‘role playing’ the identities ascribed to them and actively seek out relationships which enable them to construct alternative identities.  相似文献

高校排球课教学中异质分组教学法的应用研究     

杨荣俊 《体育科技文献通报》2020,(4):83-84

随着我国教学体制改革的不断完善,人们愈发的重视到了在实际教学过程中有关教学方法的应用,适当的教学方法应用不仅仅能够在很大程度上帮助教师获得更好的教学效果,同时还能够在根本上提升学生对于高校排球课程的理解。由此,本文拟通过对现阶段高校排球课教学过程中有关异质分组教学的方法应用进行研究,从而探究其实际的使用效果,同时帮助这一教学模式在后续高校排球课程中推广的不断深入,进而促进未来我国高校排球课程的发展。  相似文献   

人本关怀理念下普通高校体育课程改革探究     

戴飞 《体育科技文献通报》2020,(2):45-47

在升学与就业的双重压力下,无论学校、教师还是大学生本人都对普通高校体育课程存在不同程度的忽视心理与忽视行为。从体育课程的教学形式、教学内容、教学时长来看,并没有起到促进大学生综合素质提升的作用,也没有对高等教育体系完善做出应有的贡献。而在教学过程中,大学生的个人意愿、学习的主观能动性也没有得到挖掘与激发。可以说,大学体育课程缺乏以人为本的教学理念。这些问题成为大学体育课程亟待改革的弊端。  相似文献   

Professional knowledge or motivation? Investigating the role of teachers’ expertise on the quality of technology-enhanced lesson plans     

《Learning and Instruction》2020

In an expertise study with 94 mathematics teachers varying in their relative teacher expertise (i.e., student teachers, trainee teachers, in-service teachers), we examined effects of teachers' professional knowledge and motivational beliefs on their ability to integrate technology within a lesson plan scenario. Therefore, we assessed teachers' professional knowledge (i.e., content knowledge, pedagogical content knowledge, technological knowledge), and their motivational beliefs (i.e., self-efficacy, utility-value). Furthermore, teachers were asked to develop a lesson plan for introducing the Pythagorean theorem to secondary students. Lesson plans by advanced teachers (i.e., trainee teachers, in-service teachers) comprised higher levels of instructional quality and technology exploitation than the ones of novice teachers (i.e., pre-service teachers). The effect of expertise was mediated by teachers' perceived utility-value of educational technology, but not by their professional knowledge. These findings suggest that teachers’ motivational beliefs play a crucial role for effectively applying technology in mathematics instruction.  相似文献   

Promoting quality education in Chile: the politics of reforming teacher careers     

Alejandra Mizala 《教育政策杂志》2020,35(4):529-555

ABSTRACT

Reformers in developing countries increasingly seek to raise education quality. Yet we know little about the politics of improving education. One significant and instructive case of reforms designed to boost education quality comes from Chile, where in 2016 the government enacted a sweeping reform of teaching careers. This paper first uses a quantitative analysis of appearances in the news to identify key stakeholders and then turns to process tracing to analyze how and when these stakeholders influenced reform dynamics. Comparatively, the Chilean case differs from similar reforms elsewhere in Latin America due to the absence of business, the strong role of policy networks, and the final negotiated settlement with the teacher union. Theoretically, the analysis confirms general theories that emphasize the roles of distributive politics and policy networks.  相似文献   

苏北高职院校体育教学改革实施中教师阻抗的现象学分析及消除策略     

姜龙  秦博  骆勇 《体育科技文献通报》2020,(4):26-27,31

本文将教师阻抗定义为由于自身或外界因素导致教师对现有体育教学改革表现出的不满、反对、甚至抵制心理和行为。研究以教师阻抗为问题切入点,重点探究教师阻抗的内在原因。具体分析内容包括:现有体育教学改革实施现状、体育教师态度真相、冷落改革,阻抗缘由,并结合阻抗缘由提供相关消解建议。本研究主要以现象学研究方法作为方法论基础,由悬置与还原、体验与描述、反思与归纳、本质的呈现作为重点环节,参照Pollio的现象学研究方法流程,采用深度访谈,访谈对象20人,每轮访谈结束后及时将访谈录音转录为文本形式,访谈文本132571字。对访谈文本采取归纳与演绎相结合的形式,精简提炼并进行具体论证分析。结论:(1)高职院校体育改革情况并不理想,阻抗现象真实存在;(2)体育教师内心支持改革,主观排斥现象罕见,阻抗现象另有他因;(3)体育教师阻抗主要由于教师对公共体育课程教学指导纲要无从下手,各校围绕体育教学改革中需要变更新的大纲、教学方法、评价方式等工作茫然无措所导致。以此建议多安排一线教师参加培训学习;制定更为客观、易操作的教学方法和评价方式应用于高职院校体育教学一线;增大资金及人力投入;提高教师文化自信等方面,消除改革中出现的部分教师阻抗,也为高职体育改革提出一些思路。  相似文献
