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   

Protective behavior in ride-sharing through the lens of protection motivation theory and usage situation theory     

《International Journal of Information Management》2021

The frequent occurrence of security incidents in ride-sharing is a challenge for the survival of IT-enabled ride-sharing platforms. Passengers’ protective behavior is an effective means to alleviate this issue, with benefits to both the passengers and the platforms. This study explores the mechanisms of passengers’ protective behavior in the ride-sharing context by combining protection motivation theory (PMT) and usage situation theory. We test our hypotheses using data (n = 346) collected from a field survey based on a real scenario. The findings reveal that PMT and usage situation theory work well to explain passengers’ protective behavior during ride-sharing. This study explains the motivation behind passengers’ protective behavior in the ride-sharing context, extends the contents of PMT by exploring its antecedents, and extends the contents of usage situation theory by introducing a new dimension. Our findings can help ride-sharing platforms take appropriate strategies to improve passengers’ protective behavior.  相似文献   

Efficacy of using non-linear pedagogy to support attacking players’ individual learning objectives in elite-youth football: A randomised cross-over trial     

Simon J. Roberts  James R. Rudd  Matthew J. Reeves 《Journal of sports sciences》2020,38(11-12):1454-1464

ABSTRACT

The present study examined the efficacy of a coaching curriculum, based on non-linear pedagogy, on improving attacking players’ individual learning objectives (ILOs) in elite-youth football. Participants included 22 attacking players (i.e., centre-forwards, wide-players and attacking midfield players) from a professional football academy in England. The players were randomly appointed to both control (CON) and intervention (INT) periods following baseline measures. The INT (non-linear) and CON (linear) periods were both designed to support the ILOs provided to each player as part of the elite player performance plan. The study adopted a randomised cross-over design and ILOs considered important for attacking players (i.e., strong foot finishing, weak foot finishing, 1-v-1 and decision-making) were evaluated using the Loughborough Shooting Skill Test. The results showed significant differences for INT in 1-v-1 (P< 0.02) and decision-making (P< 0.01). However, there were no significant differences for strong foot finishing, weak foot finishing or time taken. These results support non-linear pedagogy in developing 1-v-1 game play and decision-making but not for technical shooting proficiency.  相似文献   

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

Reliably Assessing Growth with Longitudinal Diagnostic Classification Models     

Matthew J. Madison 《Educational Measurement》2019,38(2):68-78

Recent advances have enabled diagnostic classification models (DCMs) to accommodate longitudinal data. These longitudinal DCMs were developed to study how examinees change, or transition, between different attribute mastery statuses over time. This study examines using longitudinal DCMs as an approach to assessing growth and serves three purposes: (1) to define and evaluate two reliability measures to be used in the application of longitudinal DCMs; (2) through simulation, demonstrate that longitudinal DCM growth estimates have increased reliability compared to longitudinal item response theory models; and (3) through an empirical analysis, illustrate the practical and interpretive benefits of longitudinal DCMs. A discussion describes how longitudinal DCMs can be used as practical and reliable psychometric models when categorical and criterion‐referenced interpretations of growth are desired.  相似文献   

Intersectional agencies: Navigating predominantly White institutions as an administrator of color     

Robert J. Razzante 《Journal of International and Intercultural Communication》2018,11(4):339-357

Administrators of color in predominantly White institutions (PWI) navigate from dual positions of privilege and marginalization. Within PWIs, administrators of color experience marginalization in terms of their racial/ethnic makeup. Specifically focusing on the administrative level, 95.8% of executive provosts and 86.2% of deans of academic colleges are White. At the faculty level, nearly 10% of full professors are people of color. However, even with such exclusionary practices, 87.7% of chief diversity officers are racial minorities. The current study seeks to understand how highly educated administrators of color work for diversity, inclusion, and equity initiatives while navigating from their dual positions of marginalization and privilege. Using the theoretical lenses of co-cultural theory, dominant group theory, and intersectionality, the study seeks to understand how privilege and marginalization ebbs and flows depending on particular contexts. Findings indicate that optimizing privilege through co-cultural praxis and impeding through mentoring are two common strategies used by administrators of color.  相似文献   

Toward a moral economy of money? Money as a creature of democracy     

Jakob Feinig 《Journal of Cultural Economy》2020,13(5):531-547

ABSTRACT

This paper proposes a novel approach for understanding money users’ relation to monetary governance institutions. It first describes the stakes involved in monetary governance from a neo-chartalist/MMT perspective. In a second step, it discusses existing contributions on the relation between money issuer and money users, highlighting the literatures on central bank legitimacy and the social construction of money. It argues that neither allows for an analysis of the relation between monetary institutions and money users that takes the latter’s knowledge seriously. It then argues that the concept of moral economy can enrich scholarly analysis. Moral economies of money are defined as collective practices in which money users articulate demands as part of an understanding of money as a public good. Finally, the paper deploys the moral economy of money perspective to reconstruct the changing relation between institutions of monetary governance and money users since the Great Depression in the U.S. It shows how New Dealers silenced a moral economy of money, discusses fragmented moral economies after World War II, and the partial reemergence of such moral economies after the Great Financial Crisis. The paper concludes by discussing political implications and suggestions for further research.  相似文献

From shanzhai chic to Gangnam style: seven practices of cultural-economic mediation in China and Korea     

Tommy Tse  Victor Shin  Ling Tung Tsang 《Journal of Cultural Economy》2020,13(5):511-530

ABSTRACT

This paper examines the social construction of ‘fashionability’ – namely, what is ‘desirable’ and ‘fashionable’ – with reference to the concept ‘cultural mediators’ that foregrounds agency, negotiation and the contested practices of market actors in cultural production. It zeroes in on the cultural mediators’ attitudes and positions in the two markets by drawing on 25 in-depth interviews with industry veterans. It shows that the mediators in South Korea and China increasingly occupy hybrid occupational roles and social positions across industries and sectors yet achieve limited success in countering the status quo of Western fashion through mediation. The analysis contributes to the literature with a categorisation of seven mediation practices that shape the valuation of fashion products (i.e. ‘fashionability’) in two ways. Empirically, this categorisation illuminates how cultural mediators make reference habitually to the broader social and cultural contexts to co-construct cultural-aesthetic objects. Theoretically, it advances a cultural-economic approach to the understanding of cultural mediation and challenges the reductionist viewpoint of actor–network theory through the notion of a matrix of cultural-economic agency.  相似文献
