ABSTRACT

Background: Schoolchildren’s personality development is considered a central goal of physical education (PE). With regard to the relationship between psychological well-being and global self-esteem over the life course, the promotion of positive self-esteem is an issue of particular significance. Past research revealed that PE taught with an individualized teacher frame of reference (iTFR) and a reflexive teaching style is associated with positive effects on facets of children’s perceived sports competence. However, it remains an open question whether this teaching styles has the potential to promote positive self-esteem.

Purpose: The present study investigated whether a five-month teacher training, aimed to enhance the teachers’ iTFR and their reflexive teaching style in PE, has a positive effect on students’ perceived sports competence and their global self-esteem. To analyse the implementation quality, changes in students’ perceived iTFR and perceived reflexive teaching style were investigated.

Method: A total of 21 teachers were assigned to either an intervention group (n?=?13), receiving the five-month teacher training, or a control group (n?=?8) consisting of regular teaching without teacher training. The teacher training encompassed five three-hour consecutive sessions during which the teachers acquired theoretical and practical knowledge about the promotion of competence perceptions in PE with a reflexive teaching style and an iTFR. Between the sessions, the teachers were instructed to implement an iTFR and a reflexive teaching style into their own PE classes. To evaluate the effects of the teacher training, their students’ (N?=?315, 53.7% girls, M_age?=?13.2 y, SD_age?=?1.3 y) perceived teaching style (iTFR and reflexive teaching), perceived sports competence and global self-esteem were measured with paper-pencil questionnaires at three measurement points (pre, post and follow-up).

Findings: Linear mixed effect models showed that students of the intervention group reported an increase in their teachers’ reflexive teaching style, but there were no changes with regard to iTFR. With regard to students’ perceived sports competence and global self-esteem, there were significant interaction effects between time and group over a period of eight months (from pre-test to follow-up), indicating positive effects on these self-concept dimensions due to the teacher training.

Conclusion: The present study indicates that a long-term teacher training supports PE teachers to implement teaching styles with the aim to promote students’ self-concept. Furthermore, the findings lead to the assumption that a more pronounced iTFR in combination with an enhanced reflexive teaching style has the potential to positively influence schoolchildren’s perceived sports competence and global self-esteem.  相似文献   

Application of network meta-analysis in the field of physical activity and health promotion

Continued advancement in the field of physical activity and health promotion relies heavily on the synthesis of rigorous scientific evidence. As such, systematic reviews and meta-analyses of randomized controlled trials have led to a better understanding of which intervention strategies are superior (i.e., produce the greatest effects) in physical activity-based health behavior change interventions. Indeed, standard meta-analytic approaches have allowed researchers in the field to synthesize relevant experimental evidence using pairwise procedures that produce reliable estimates of the homogeneity, magnitude, and potential biases in the observed effects. However, pairwise meta-analytic procedures are only capable to discerning differences in effects between a select intervention strategy and a select comparison or control condition. In order to maximize the impact of physical activity interventions on health-related outcomes, it is necessary to establish evidence concerning the comparative efficacy of all relevant physical activity intervention strategies. The development of network meta-analysis (NMA)—most commonly used in medical-based clinical trials—has allowed for the quantification of indirect comparisons, even in the absence of direct, head-to-head trials. Thus, it stands to reason that NMA can be applied in physical activity and health promotion research to identify the best intervention strategies. Given that this analysis technique is novel and largely unexplored in the field of physical activity and health promotion, care must be taken in its application to ensure reliable estimates and discernment of the effect sizes among interventions. Therefore, the purpose of this review is to comment on the potential application and importance of NMA in the field of physical activity and health promotion, describe how to properly and effectively apply this technique, and suggest important considerations for its appropriate application in this field. In this paper, overviews of the foundations of NMA and commonly used approaches for conducting NMA are provided, followed by assumptions related to NMA, opportunities and challenges in NMA, and a step-by-step example of developing and conducting an NMA.  相似文献   

中美竞技体育国际竞争力比较研究     

朱玉霞 《河北体育学院学报》2020,34(1):37-42

运用双框架模型对中美竞技体育国际竞争力进行比较研究。认为:①从显现性框架分析,美国竞技体育国际竞争力一直稳定处于高位,而中国则呈现以2008年为峰顶的倒“U”型发展特征,且与美国还存在一定差距;②从解释性框架分析,美国竞技体育国际竞争力已趋于顶峰,而中国稳步提升;③中国竞技体育发展潜力巨大,但短时间内难以赶超美国;④“举国体制”有利于中国竞技体育显现性竞争力的提升,但与美国社会办竞技体育的发展模式相比,市场、社会在竞技体育发展中的作用发挥不足,不利于高经济性项目、高欣赏性项目的发展;⑤坚持“举国体制”、承办2022年冬奥会有利于中国竞技体育显现性竞争力的提升和冬季项目的发展,但同样存在竞技体育项目布局转型的困难和群众体育基础薄弱的困境。  相似文献   

我国冬季项目跨界跨项选材研究与启示     

郝月蓉 《河北体育学院学报》2020,34(3):42-46

运用文献资料法和逻辑分析法，对冬季项目跨界跨项选材问题进行辩证分析。认为，2022年北京冬奥会、政府专项政策导向及国内外成功的跨界经验，为我国开展冬季项目跨界跨项选材工作提供了重要的机遇和支持，但跨界跨项选材任务艰巨、冬季项目人才缺口大、运动员培养时间不足、跨界跨项风险大等问题也不容忽视。为进一步做好跨界跨项选材工作，为我国冬季项目持续发展提供充足的人力支持，应积极落实国家政策，做到科学跨选；依托同项群项目选材，跨用传统优势项目人才；抓住冬奥发展机遇，尽快建立完善的人才培养体系。  相似文献   

服务于乡村治理的民间武术组织转化路径研究     

张望龙 《河北体育学院学报》2020,34(5):86-90

自治、法治、德治“三治合一”的乡村治理体系，为探索民间武术组织服务于乡村治理提供了新思路。在传统社会，民间武术组织以武德传承强化乡村德治机制，以门规戒约规范乡村法治秩序，以家长制参与乡村自治实践。而进入现代社会，民间武术组织服务于乡村治理面临着传统德治弱化、法治建设不完善、参与自治机制不健全三方面的困境。提出，民间武术组织要建立新的道德体系，营造乡村治理的德治氛围；加强组织治理，强化乡村治理的法治理念；深化自治实践，主动承担乡村治理职责功能，旨在为更好促进民间武术组织有效治理、推动乡村发展提供参考。  相似文献   

唐代保辜制度对当代刑事和解制度的启示     

刘喆玉 《保定学院学报》2020,(3):36-42

保辜制度是我国古代一项极具特色的法律制度,在唐代臻于成熟。保辜制度的目的在于确定伤害行为与结果的因果关系,具有对受害人进行保护、对加害人赋予悔改机会以平稳修复社会关系的深层内涵,从某种意义上其与当代的刑事和解制度的目的有着一定的相通性,对于完善我国的刑事和解制度具有积极意义。借鉴唐代保辜制度理念,可以从扩大适用范围、增加审查起诉阶段观察期、加大司法机关参与力度、实行执行阶段保证人制度等方面完善我国刑事和解制度。  相似文献

鉴于在当前轮机模拟器中油水分离器控制模块缺少含油质量分数的仿真、报警记录和参数的存储以及人机交互界面的设计等功能,通过分析RWO油水分离器的工作原理和运行逻辑,提出一种新型嵌入式油水分离器仿真模块。根据模块的功能需求,选取STM32F103xx为主芯片,W5100为网络芯片,通过Altium Designer设计16DI8DO4AI印制电路板(printed circuit board,PCB)。进行嵌入式操作系统μC/OS-II的裁剪和移植,根据所使用的模块对板载外设库进行初始化,基于运行逻辑进行多任务程序设计。试验表明,嵌入式油水分离器控制模块能够实现含油质量分数的采集,适时触发含油量超限报警并同步更新报警信息和阀位,用TFT液晶屏能够实现对参数值和运行状态的实时显示。该模块具有很高的应用价值和良好的可扩展性。  相似文献

针对救助船消防训练中存在的海况复杂,对外消防炮射流受风影响大,往往无法准确控制其射向目标区域的问题,在理想状态下射流理论的基础上探究风对射流轨迹的影响,建立自然风条件下射流轨迹的数学模型,模拟对外消防炮射流的运动情况。应用3ds Max构建船舶模型,用Unity3D构建救助船在面临大风浪、遇险船着火等状况时对外消防系统的工作场景,提出一种精确构建粒子系统轨迹的方法,使射流模型能精确体现在场景中。通过虚拟现实设备能实现救助船对外消防培训仿真系统的立体显示和人机交互,起到更好的虚拟仿真和培训效果。  相似文献   

Digital Module 05: Diagnostic Measurement—The G‐DINA Framework https://ncme.elevate.commpartners.com     

Wenchao Ma  Jimmy de la Torre 《Educational Measurement》2019,38(2):114-115

In this ITEMS module, we introduce the generalized deterministic inputs, noisy “and” gate (G‐DINA) model, which is a general framework for specifying, estimating, and evaluating a wide variety of cognitive diagnosis models. The module contains a nontechnical introduction to diagnostic measurement, an introductory overview of the G‐DINA model, as well as common special cases, and a review of model‐data fit evaluation practices within this framework. We use the flexible GDINA R package, which is available for free within the R environment and provides a user‐friendly graphical interface in addition to the code‐driven layer. The digital module also contains videos of worked examples, solutions to data activity questions, curated resources, a glossary, and quizzes with diagnostic feedback.  相似文献
