习惯行为、执行意向与青少年身体活动意向与行为:基于计划行为理论的扩展模型     

王丽娟  郑丹蘅 《上海体育学院学报》2020,(2):22-32

在计划行为理论(TPB)的基础上,引入身体活动习惯行为与执行意向,构建扩展TPB(METPB)模型,检验该模型对9~19岁青少年群体的中高强度身体活动(MVPA)的适用性,探讨该模型对小学、初中及高中阶段青少年MVPA影响的差异。结果显示:假设模型的拟合度可以接受,纳入习惯行为与执行意向后,METPB显著地提高了其对身体活动行为的解释力。态度和感知行为控制对MVPA行为意向有显著性影响,解释了31.4%的行为意向方差;行为意向和习惯行为对MVPA行为有显著性影响,解释了18.7%的行为方差;执行意向加强了行为意向朝实际行为的转换。METPB模型对于不同学习阶段青少年MVPA意向及行为的影响有显著性差异。其中:主观规范对小学生与初中生MVPA意向产生了显著性影响,而对高中生的MVPA意向并无显著性影响;感知行为控制对3个阶段学生的MVPA意向产生的影响随着学习阶段的上升不断增强。建议:在对于青少年身体活动的干预中,政府、家庭、学校应重视培养学生对于身体活动参与的正确态度,提高其参与身体活动的意愿,培养其参与身体活动的行为习惯,且在对青少年身体活动干预时考虑学习阶段的差异。  相似文献   

定向行走课程与教学专业能力研究     

杞昭安 《现代特殊教育》2020,(2):26-37

从感觉训练、概念发展、行动技能、定向系统、求助技能、安全议题、小区资源与大众运输系统七个方面选取50项能力指标,对海峡两岸64名担任定向行走课程的教师进行问卷调查。调查结果显示:大多数被调查者认可这50项能力指标;定向行走教师对自己的课程与教学专业能力认可度多为中等,需要进一步作培训。同时发现,在定向行走课程与专业能力各向度的重要程度上,海峡两岸定向行走教师的认知有显著差异,各向度胜任程度的差异更加明显;而定向行走教师的年龄对定向行走课程与教学专业能力在重要程度和胜任程度上并没有显著差异;海峡两岸担任定向行走课程的教师,多数认为有培训的必要。建议将重要性在3.5以上的题目编制为《定向行走专业能力检核表》;将定向行走专业能力胜任程度在3.5以下的向度作为定向行走师资培训的参考。  相似文献   

《黄帝内经》“阴阳二十五人”人格理论的优势与不足     

王彦 《教育教学论坛》2020,(19):98-99

《黄帝内经》是中医重要典籍,它将五行与人体形态、体质、人格特征等属性进行联系,提出“五形人”并推演出“阴阳二十五人”学说。“阴阳二十五人”包含了理论驱动式、演绎式的人格理论,不同于西方数据驱动式、归纳式的人格理论,因此具有重要的理论价值。与此同时,该学说也存在一些明显的瑕疵,需要加以完善和修正。  相似文献   

体育强国建设下幼儿家庭体育的现象学研究     

白翠瑾  李哲  杨光 《沈阳体育学院学报》2020,(2):34-40

2019年是中国体育划时代的一年,以《体育强国建设纲要》的颁布为起点开启了体育事业的全新征程。幼儿家庭体育是学前教育的薄弱环节,父母的体育引导是家庭体育的重中之重。采用现象学方法,以幼儿父母访谈为抓手诠释幼儿家庭体育现象。结果认为:父母观念下幼儿家庭体育的掣肘包括主观因素的理念束缚、安全焦虑、指导孱弱、精力局限,客观因素的经济无力、规划无序、保障无依。针对存在障碍提出化解路径:通过革新理念调解传统意识的偏颇,通过制定指南消解育教于体的困惑,通过家园共育缓解精力、经济的压力,通过社会支持纾解供需之间的失衡。  相似文献   

Three suggested teaching strategies for students who are deaf or hard of hearing     

Tina J. Herring  M. Lynn Woolsey 《Support for Learning》2020,35(3):346-358

This paper addresses current issues in deaf education including poor academic progress and employment outcomes of individuals who are deaf and hard of hearing (D/HH) as well as provides suggestions for improving overall academic achievement of this population. Specifically, three instructional strategies are recommended for teachers: choral responding, response cards, and peer tutoring. These three strategies have been shown to increase active student responding in classrooms for children who are typically developing and children who have disabilities. For international deaf students in countries that may rely on volunteers who lack basic requisite skills these general education teaching strategies are easy to use even by novice teachers. Recommendations are tendered for how teachers can include these simple teaching strategies in classrooms serving students who are D/HH.  相似文献   

Impact of combining data from multiple instruments on performance of patient-based real-time quality control     

Qianqian Zhou  Tze Ping Loh  Tony Badrick  Chun Yee Lim 《Biochemia medica : ?asopis Hrvatskoga dru?tva medicinskih biokemi?ara / HDMB》2021,31(2)

IntroductionIt is unclear what is the best strategy for applying patient-based real-time quality control (PBRTQC) algorithm in the presence of multiple instruments. This simulation study compared the error detection capability of applying PBRTQC algorithms for instruments individually and in combination using serum sodium as an example.Materials and methodsFour sets of random serum sodium measurements were generated with differing means and standard deviations to represent four simulated instruments. Moving median with winsorization was selected as the PBRTQC algorithm. The PBRTQC parameters (block size and control limits) were optimized and applied to the four simulated laboratory data sets individually and in combination.ResultsWhen the PBRTQC algorithm were individually optimized and applied to the data of the individual simulated instruments, it was able to detect bias several folds faster than when they were combined. Similarly, the individually applied algorithms had perfect error detection rates across different magnitudes of bias, whereas the error detection rates of the algorithm applied on the combined data missed smaller biases. The performance of the individually applied PBRTQC algorithm performed more consistently among the simulated instruments compared to when the data were combined.DiscussionWhile combining data from different instruments can increase the data stream and hence, increase the speed of error detection, it may widen the control limits and compromising the probability of error detection. The presence of multiple instruments in the data stream may dilute the effect of the error when it only affects a selected instrument.  相似文献   

From user-generated data to data-driven innovation: A research agenda to understand user privacy in digital markets     

《International Journal of Information Management》2021

In recent years, strategies focused on data-driven innovation (DDI) have led to the emergence and development of new products and business models in the digital market. However, these advances have given rise to the development of sophisticated strategies for data management, predicting user behavior, or analyzing their actions. Accordingly, the large-scale analysis of user-generated data (UGD) has led to the emergence of user privacy concerns about how companies manage user data. Although there are some studies on data security, privacy protection, and data-driven strategies, a systematic review on the subject that would focus on both UGD and DDI as main concepts is lacking. Therefore, the present study aims to provide a comprehensive understanding of the main challenges related to user privacy that affect DDI. The methodology used in the present study unfolds in the following three phases; (i) a systematic literature review (SLR); (ii) in-depth interviews framed in the perspectives of UGD and DDI on user privacy concerns, and finally, (iii) topic-modeling using a Latent Dirichlet allocation (LDA) model to extract insights related to the object of study. Based on the results, we identify 14 topics related to the study of DDI and UGD strategies. In addition, 14 future research questions and 7 research propositions are presented that should be consider for the study of UGD, DDI and user privacy in digital markets. The paper concludes with an important discussion regarding the role of user privacy in DDI in digital markets.  相似文献
