Preservice teachers perspectives and experiences teaching personal and social responsibility     

K. Andrew R. Richards  Jennifer M. Jacobs  Victoria Nicole Ivy  Michael A. Lawson 《Physical Education & Sport Pedagogy》2020,25(2):188-200

ABSTRACT

Background: Pedagogical models have become an established component of physical education over the past several decades. One such model, the Teaching Personal and Social Responsibility model, has gained momentum in practice and research, though little is known regarding its use in preservice teacher training. The model follows a flexible format focused on teaching life skills (e.g. leadership) that can be applied in all lived ecologies. Occupational socialization theory provides insight into the pretraining and teacher education experiences of preservice teachers that shape their understanding and practice of physical education and associated pedagogical models.

Aims: The purpose of this study was to understand the influence of a sequence of methods courses and early field experiences on U.S. preservice teachers’ understanding and implementation of the teaching personal and social responsibility model with youth from a community affected by poverty.

Method: This study took on a phenomenological and social constructivist approach. Ten preservice teachers (9 males, 1 female) took part in the study. The participants were an average age of 22.10 years old (SD?=?4.38) and seven identified as White and three as Black. Each participant was enrolled in methods and early field experience coursework that provided scaffolded training in primary education in a community affected by poverty. Preservice teachers team-taught groups of 10–15 children twice a week along with one day committed to on-campus reflection. Data collection included autobiographical essays, critical incident reports, reflective journals, non-participatory observations and field notes, and semi-structured interviews. Data were analyzed deductively through the lens of occupational socialization theory, and inductively as theory divergent trends were sought. Open and axial coding was completed with member checking throughout, resulting in a final set of themes and subthemes.

Findings: The preservice teachers initially struggled to connect with their students due to conflicting backgrounds, but the teaching personal and social responsibility model guided the relationship-building process. As the model was continuously utilized, more empathy and care were shown towards the children. Preservice teachers felt there was a lack of progression in positive behaviors but were able to empower youth and felt that the model was culturally relevant. Overtime, the students began to appreciate the affective domain despite the challenge of working in a community affected by poverty through frustration towards the larger system limiting any potential progress was present.

Conclusions: Subjective theories transitioned to include relationship building and life skills learning, likely because of the extended field experience and faculty support. The preservice teachers desire to connect with and teach the students well displays the connection between models-based practice and positive relationships. Preservice teachers’ knowledge of their students was limited as it was based on secondhand knowledge of youth, teacher educators, and school staff. Evidence indicates some cultural responsiveness development though there were also elements of a deficit model due to white privilege and class differences. Further work explicitly integrating a culturally relevant approach and social justice in teacher education programming should occur.  相似文献   

在军校引入TMF训练方法可行性的研究     

杨祥红  王正磊  陈宏昱  窦文博 《当代体育科技》2020,(1):33-34

抗阻力训练是军校体能训练常用的训练方法,而训练至肌肉失败(TMF)作为抗阻力训练中一种新兴的训练方法,已经在健身领域引起越来越广泛的关注,并已经逐步应用于专业运动员训练中。TMF在军校这类对体能要求较高的机构内具有广阔的应用前景,但现阶段TMF在军校还未得到推广,大部分军校仍然沿用过去的传统抗阻力训练模式。本文从介绍抗阻力训练与TMF的相关概念出发,分析了TMF的作用机制,提出了在军校训练中引入TMF的可行训练项目。为了进一步研究TMF对于军校学员体能训练效果的影响,本文选取成绩相近的部分学员进行分组对照实验,运用统计学方法处理实验结果,从而证明了TMF对于学员体能具有明显提升作用,最后对本次研究工作进行了总结和展望。  相似文献

基于ICWGT和灰色关联分析法的起重机安全评价     

肖汉斌  熊楚宸  祝锋  刘敏 《上海海事大学学报》2020,41(2):117-122

针对目前起重机安全评价过于依赖主观权重且忽视起重机安全状态变化趋势的问题，建立基于改进博弈论组合赋权法（improved combination weighting method of game theory，ICWGT）和灰色关联分析法的起重机安全评价体系。在该评价体系中，收集样本数据以确定评价值，构建评价等级空间来计算起重机行为特征序列与标准行为特征序列的关联系数。运用ICWGT在层次分析法和信息熵 未确知测度理论确定的主、客观权重中寻找平衡。充分考虑专家经验和样本数据，确定优化权重以改善关联系数的分配问题，从而获取起重机灰色关联度评价值和安全等级，旨在对起重机安全状态变化趋势进行更加准确的定量描述和定性分析。实例分析验证了该评价体系的有效性。  相似文献   

基于正态云可拓理论的锚泊安全评价     

鲁峰  李伟  宁君  于仁海 《上海海事大学学报》2020,41(4):30-35

为提高锚泊安全评价精度，保障船舶锚泊安全，针对传统锚泊安全评价方法未考虑评价等级界限的不确定性和模糊性等问题，将正态云可拓理论应用于锚泊安全评价中。采用层次分析法和基于可拓学的简单关联函数确定权重的方法分别确定锚泊安全评价指标的主观和客观权重，通过经验因子将主观与客观权重进行结合。构建基于正态云可拓理论的锚泊安全评价模型，计算待评物元与标准可拓物元的关联度，通过信息熵理论确定锚泊安全等级。根据信息熵理论定义可信因子，使得评价结果的可信度易于定量计算。实例计算验证了本模型的有效性和优越性。  相似文献   

面向科技强国的科技评价制度需要科技体制的结构性变革          下载免费PDF全文

李培楠  张苏雁 《中国科学院院刊》2019,34(5):552-559

习近平总书记在2016年"科技三会"上发出建设世界科技强国的号召。建设世界科技强国不仅需要资源要素的支撑,更需要有将这些要素进行合理配置的制度安排,需要新的模式来激发新的创造力。其中,对评价制度的改革在寻找科技体制新模式的改革关键举措中具有基础性作用。为此,回顾过去,文章从科技体制与科技评价的关系视角重新审视这一问题,从回归科技评价的本源出发,探究科技评价异化的体制问题。相应地,面向未来,文章从改革主线、改革结构、评价体系3个方面提出推动以科技创新为核心的科技体制改革建议,为建成百年科技强国提供政策依据。  相似文献   

Journalism in Disguise: Standpoint Theory and the Ethics of Günter Wallraff’s Undercover Immersion     

Willa McDonald 《Journalism Practice》2020,14(1):34-47

ABSTRACT

Deception is a key element of immersive undercover journalism, achieved through the omission of information, the perpetuation of misconceptions, or possibly the assumption of a false identity. Usually when proponents defend going undercover, they use the-ends-justify-the-means arguments; that despite the journalist’s duplicity, public benefit outweighs the dishonesty that lies at the heart of the practice. Yet, such statements are usually made in the absence of in-depth theoretical analysis. This paper seeks to redress this by applying Standpoint Theory, testing it against the work of Günter Wallraff, Germany’s lauded but controversial undercover journalist who uses disguises to report on that country’s marginalized and disadvantaged. While the authors applaud Wallraff’s exposure of the deplorable illegal and immoral dealings he uncovers, and do not seek to dismiss the significant results he has achieved, this paper uses the case study of his work to test the applicability of Standpoint Theory to undercover journalism, concluding that even under this accommodating theory, there may be ethical limits to journalism’s most ethically contentious practice.  相似文献   

基于生态位理论的高校众创空间建设策略研究     

张超  张育广 《科技管理研究》2019,39(8)

高校众创空间作为高校创新创业人才培养的新兴重要载体，对高校创新创业教育具有重大作用。在创新驱动发展战略背景下，各高校结合自身优势对众创空间建设模式进行了各具特色的实践探索，但在理论研究方面仍缺乏科学梳理和系统思维，在空间布局和功能定位上，缺乏从生态系统的视角打造高校创新创业生态系统。本文通过阐释众创空间的内涵，分析高校众创空间的存在问题，在高校创新创业教育的实践经验基础上，探索以生态位理论视角剖析众创空间的系统结构模型以及要素互动关系，提出高校众创空间生态系统构建的建设策略，全面提升高校众创空间的科学发展。  相似文献
