This study seeks to understand the emotional connection of teachers' academically productive talk (APT) with student learning from the students' perspective. Using a sample of 2,225 students (N_{7th grade} = 1,146 and N_{8th grade} = 1,079) from 16 middle schools in a city of China, we investigate the relationship between students' perceptions of their teachers’ APT, student emotions (enjoyment and anxiety) and their discursive engagement with others in the mathematics classroom. Results from structural equation modelling and mediation analysis show that after controlling for gender, family resources and mathematics achievement, student-perceived teacher APT was positively associated with their discursive engagement with classmates. Furthermore, student enjoyment and anxiety in class mediated the relationship between student-perceived teacher APT and student discursive engagement with classmates. Multi-group analysis revealed that the model was invariant across genders and grades, indicating that the associations were applicable to male and female students as well as to seventh and eighth graders. These findings shed light on the emotional relationship of teacher APT with the discursive engagement of their students. Although prior research observes a positive relationship between teacher productive classroom talk and student discursive engagement primarily through classroom observations and teacher reflections, this study provides evidence from the students’ perspective and highlights the mediating role of student emotions in the relationship.  相似文献   

Resolving the amalgam: connecting pedagogical content knowledge,content knowledge and pedagogical knowledge     

Vanessa Kind  Kennedy K. H. Chan 《International Journal of Science Education》2019,41(7):964-978

ABSTRACT

This paper concludes the Special Issue (SI) ‘Probing the Amalgam: the relationship between science teachers’ content, pedagogical and pedagogical content knowledge’. We review the five papers (Sorge et al; Gess-Newsome et al; Kind; Pitjeng-Mosabala and Rollnick; and Liepertz and Bronowski) by discussing evidence these present regarding the relationships between content knowledge (CK), pedagogical knowledge (PK) and pedagogical content knowledge (PCK); the development of CK, PK and PCK in novice and experienced secondary science teachers and how CK, PK and/or PCK impact students’ learning. In conclusion, we draw these findings together in offering proposals for future research via reconsideration of Shulman’s amalgam. This includes post-hoc examination of a PCK model known as ‘the Consensus Model’ (Gess-Newsome, [2015]. A model of teacher professional knowledge and skill including PCK: Results of the thinking from the PCK Summit. In A. Berry, P. J. Friedrichsen, & J. Loughran (Eds.), Re-examining Pedagogical Content Knowledge in Science Education (pp. 28–42). New York, NY: Routledge; Neumann, Kind, & Harms [2018]. Probing the amalgam: The relationship between science teachers’ content, pedagogical and pedagogical content knowledge.

Validation of the swimming competence questionnaire for children

ABSTRACT

Two studies were employed to test the reliability and validity of the Swimming Competence Questionnaire (SCQ) among primary school children. Study 1 was a cross-sectional survey in 4959 primary school children. Study 2 was a pre-post-test quasi-experiment among 1609 primary school children who underwent a 20-lesson learn-to-swim programme. In Study 1, exploratory structural equation modelling revealed excellent goodness-of-fit and scale reliability for a two-factor model comprising distance and skill factors, which supported the construct and convergent validity. SCQ scores were significantly and positively correlated with swimming outcomes (i.e., self-efficacy, intention, swimming frequency), which supported SCQ’s concurrent and criterion validity. Average variance extracted for the SCQ factors exceeded cut-off criteria supporting discriminant validity. In Study 2, pre-test SCQ scores correlated significantly and positively with the SCQ scores, self-efficacy, intention, and swimming frequency at post-test, which supported SCQ’s test-retest reliability and predictive validity. Positive intraclass correlation between SCQ scores and coach ratings at post-test provided evidence for SCQ’s inter-rater reliability. SCQ scores significantly improved at post-test, which supported SCQ’s ecological validity. In conclusion, findings indicate that the SCQ is a valid and reliable measure to assess primary school children’s swimming competence, in terms of swimming distance and basic water survival skills.  相似文献

Examining public acquisition of science knowledge from social media in Singapore: an extension of the cognitive mediation model     

Shirley S. Ho  Xiaodong Yang  Amber Thanwarani  Juliana M. Chan 《亚洲交流杂志》2017,27(2):193-212

This study extends the cognitive mediation model (CMM) by examining the role of social media in cultivating public science knowledge. A sample of 901 Singaporeans was collected through an online survey panel. The results showed that the CMM could be applied to a social media context with a focus on science literacy. Specifically, the findings indicated that people with higher levels of surveillance gratification and social utility motivations tended to pay more attention and to elaborate more about science news that they encounter on social media. Likewise, people with greater social utility motivation tended to engage in greater interpersonal discussions on social media. Notably, attention to news on social media had an indirect association with science knowledge through news elaboration and interpersonal discussion on social media. Implications for theory and practice for science communication were discussed.  相似文献   

网络信息资源著作权风险规避中的委托代理关系     

李婵  徐龙顺  张文德 《图书情报工作》2017,61(22):45-51

[目的/意义]通过对网络信息资源著作权风险中著作权人与网络服务提供者的博弈分析,在利益均衡的基础上提出著作权风险规避的策略。[方法/过程]运用委托代理理论的基本原理,分析著作权人与网络服务提供者的委托代理关系,构建信息不对称条件下著作权人为风险中性和风险规避时的委托代理模型,并进一步对两种情况下的各绩效指标进行探讨。[结果/结论]在委托代理机制下,著作权人与网络服务提供者在风险规避上的利益具有一致性;在两种不同情况下著作权人的激励程度、网络服务提供者的努力程度以及总的期望收益均有显著变化;著作权人的激励程度以及双方的最终收益与网络服务提供者的努力程度、努力成效、风险规避程度、项目完成能力等因素密切相关。基于此,可以通过健全奖惩激励机制、完善利益补偿机制、强化监督管理机制来规避网络信息资源著作权中的风险问题,实现委托代理双方收益的帕累托最优。  相似文献

新手教师实践性知识生成机制研究——以"多对多"师徒结对为分析对象     

汪明帅  王亚君  赵婵 《教育发展研究》2021,41(12):37-44

如何充分发挥师徒结对在新手教师实践性知识生成中的作用是本研究关注的焦点问题.本研究采取质化研究中的个案研究取向,对这一焦点问题进行了考察.个案显示,受惠于"多对多"师徒结对这一媒介,将新手教师所遭遇的问题变成研究的课题,通过师徒共同体一起探索,逐步解决问题,最终形成了追求契合学生心理特征的课堂管理的实践性知识.基于研究可知,实践性知识是在具体的教育教学情境中,通过不断建构、不断应用和不断改进而动态生成的.呈现出螺旋上升的样态;师徒结对是促进教师实践性知识生成的重要途径,"多对多"师徒结对作为师徒结对的创新形式,不但给新手教师提供了更多交流与沟通的机会,尤其是非正式的交流与沟通机会,还天然具备了相互学习、互相借鉴的机制,在很多方面更有助于新手教师实践性知识生成.需要注意的是,在"多对多"师徒结对的具体落实过程中,尤为需要统筹"多对多"师徒结对中师傅之间的指导节奏,并关照"多对多"师徒结对中不同新手教师特定的发展需求.  相似文献   

Faculty Liaisons: an embedded approach for enriching teaching and learning in higher education     

Afsaneh Sharif  Ashley Welsh  Jason Myers  Brian Wilson  Judy Chan  Sunah Cho 《International Journal for Academic Development》2019,24(3):260-271

This paper explores the experiences of a group of academic developers who support educational development work as Faculty Liaisons at a large, research-intensive university. These academic developers inhabit complex ‘third spaces’, providing support through an embedded partnership relationship that requires lateral movement across functional and organizational boundaries to create new professional spaces, knowledge, and relationships. The authors utilize narrative inquiry and auto-ethnographic approaches to present an interpretive qualitative analysis of their experiences supporting Faculty and University projects across complex and evolving organizational boundaries. From this analysis, they highlight key roles and responsibilities associated with their blended context and identify challenges that academic developers who occupy third spaces within academic organizations face as they negotiate competing interests, identities, and requirements associated with the diverse range of their projects and the blended experience of working in scholarly and administrative, central- and Faculty-based roles. The lessons they have learned from these experiences will be of particular interest to academic developers who are experiencing the flux of change within higher education settings that are impacting teaching and learning practices both for faculty in the classroom and for those across the institution who support them.  相似文献
