High school students' evolving alternative conception related to the volume of gas: A Lakatosian perspective     

Chulkyu Park  Seonyeong Mun  Hun-Gi Hong 《科学教学研究杂志》2024,61(3):674-705

The purpose of this case study, informed by a Lakatosian perspective, is to identify how an alternative conception that originates in present learning but is related directly to subsequent learning contexts can be constructed. Before the study, one of the authors found by accident that a student who had learned about Avogadro's principle and chemical reaction in South Korea constructed an alternative conception related to the volume of gas. Later, we identified seven Korean high school students with the alternative conception through a test and analyzed their underlying understandings qualitatively through interviews. The results show that they had a scientific conception—core conception—and intuitive assumptions about implicit information of external representations—implicit assumptions—in common. The students' implicit assumptions could be divided into three types again: core assumption, auxiliary assumption, and context-inducing assumption. The core assumption, like the core conception, played a significant role in constructing the alternative conception (hard core), while the auxiliary assumptions were incomplete implicit assumptions to protect the alternative conception (protective belt). The context-inducing assumption was an implicit assumption bringing the context of the subsequent curriculum, and the core conception and the core assumption could be interpreted in this induced context. At the end of the study, the implications related to learning progressions were discussed.  相似文献   

Teacher commitment and its effects on student achievement in American high schools     

Insim Park 《Educational Research and Evaluation》2013,19(5):461-485

This study explored the effects of teacher commitment on student achievement. Three teacher commitment dimensions of organizational, professional, and student commitment were derived. The three-dimensional teacher commitment measurement model was tested by a confirmatory factor analysis. Then, the relationships among individual and organizational variables, teacher commitment, and student achievement were analyzed by a 2-level hierarchical linear modeling method. As the results, the greater portions of teacher commitment and student achievement variances were within schools. The individual and organizational variables had differential impacts on each teacher commitment dimension. Finally, while teacher commitment effects on student achievement were differentially found depending on teacher commitment dimensions at the individual level, there was no evidence to support significant impacts of teacher commitment on student achievement at the organizational level.  相似文献   

Why are we using action learning and in what contexts?     

Sunyoung Park  Ingu Kang  Taryn R. Valencic  Yonjoo Cho 《Action Learning: Research and Practice》2013,10(1):4-24

The purpose of this study was to examine the contexts in which action learning has been used and provide implications for the design of action learning programmes. We performed a content analysis of 127 articles (case studies and case reports included) published in Action Learning: Research and Practice between 2004 and 2012. In this study, we address the following research questions: (a) In what contexts has action learning been used? (b) What are the distinctive features of cases identified? (c) What are the implications for the design of action learning programmes? The results showed that the UK and European countries have most frequently used action learning, and the most dominant purposes for action learning were leadership development, organization development, and professional development. We also elaborated on design considerations and implications for action learning research and practice.  相似文献   

Influential factors for knowledge creation practices of CTE teachers: mutual impact of perceived school support, transformational leadership, and work engagement     

Ji Hoon Song  Sang Hoon Bae  Sunyoung Park  Hye Kyoung Kim 《Asia Pacific Education Review》2013,14(4):467-482

This study examined the structural relationships among perceived school support, transformational leadership, teachers’ work engagement, and teachers’ knowledge creation practices. It also investigated the mediating effects of transformational leadership and work engagement in explaining the association between perceived school support and knowledge creation practices. Samples included 284 career and technical education teachers in the United States. Structural equation modeling was employed. Perceived school support was positively associated with transformational leadership and teachers’ work engagement, but had no direct impact on knowledge creation practices. Transformational leadership was found to affect knowledge creation practices, but not work engagement of teachers. Although a supportive school climate had no direct relationship with knowledge creation practices, it indirectly affected this outcome variable through transformational leadership and teachers’ work engagement. The results suggest that in order to increase teachers’ knowledge creation activities, a supportive school climate should be provided with efforts to improve teachers’ work engagement and transformational behaviors of the principal.  相似文献   

Cross-cultural language learning and web design complexity     

Ji Yong Park 《Interactive Learning Environments》2013,21(1):19-36

Accepting the fact that culture and language are interrelated in second language learning (SLL), the web sites should be designed to integrate with the cultural aspects. Yet many SLL web sites fail to integrate with the cultural aspects and/or focus on language acquisition only. This study identified three issues: (1) anthropologists’ cultural models mostly adopted in cross-cultural web user interface have been superficially used; (2) web designers deal with culture as a fixed one which needs to be modeled into interface design elements, so (3) there is a need for a communication framework between educators and design practitioners, which can be utilized in web design processes. This paper discusses what anthropology can contribute to language learning, mediated through web design processes and suggests a cultural user experience framework for web-based SLL by presenting an exemplary matrix. To evaluate the effectiveness of the framework, the key stakeholders (learners, teachers, and designers) participated in a case scenario-based evaluation. The result shows a high possibility that the framework can enhance the effective communication and collaboration for the cultural integration.  相似文献   

Stabilization of switched linear singular systems with state reset     

Xiaoqing Xiao  Ju H. Park  Lei Zhou 《Journal of The Franklin Institute》2019,356(1):237-247

This paper investigates the stability and stabilization of switched linear singular systems with state reset at switching instants. Based on the dynamics decomposition of singular subsystems, a sufficient stability condition for the system with the given state reset is obtained. Then, the stabilization problem by state reset is investigated and an algorithm for computing the reset matrices is presented. The obtained results extend some previous works on both singular switched systems and reset control for normal switched systems. Finally, a numerical example is presented to illustrate the effectiveness of the proposed approach.  相似文献   

The current state of human performance technology: A citation network analysis of Performance Improvement Quarterly, 1988–2010     

Yonjoo Cho  Sung Jun Jo  Sunyoung Park  Ingu Kang  Zengguan Chen 《Performance Improvement Quarterly》2011,24(1):69-95

This study conducted a citation network analysis (CNA) of human performance technology (HPT) to examine its current state of the field. Previous reviews of the field have used traditional research methods, such as content analysis, survey, Delphi, and citation analysis. The distinctive features of CNA come from using a social network analysis approach to see relational and network patterns in the citation data. This CNA found that the Performance Improvement Quarterly network showed more widely but loosely connected and less centralized structural attributes than the human resource development network; the 10 most influential articles in the field were identified; frequently co‐cited articles were recognized as having a strong relationship by subsequent researchers; and five cohesive subgroups showed key topics in the field (performance, instructional design, performance support, organization/workplace, and transfer of training). Implications from the results of the CNA were elaborated on for future research in HPT.  相似文献   

Embodied inter-referencing: encounters with and among “Asian” students in the Australian classroom     

Jane Chi Hyun Park 《Inter-Asia Cultural Studies》2019,20(2):271-289

ABSTRACT

This essay examines the pedagogical practice of referencing my experiences as a transnational Korean American woman in the classroom and considers how it opens up space for domestic and international students of East, Southeast, and South Asian backgrounds to reflect on their different identities, histories, and cultures. In particular, it focuses on how this practice enables Asian students to share their experiences of and insights about racial difference, racism, and whiteness in Australia and other parts of the world. Building on the concept of Asian “inter-referencing” from Chua Beng Huat (2015), I coin the term “embodied inter-referencing” to describe the strategic ways I use autobiographical narrative to create an inclusive, interactive, and mutually respectful learning space. I centre here on how some Asian students respond to this strategy by telling their own stories and in the process, create transnational, diasporic, and inter-Asian affective communities inside and outside the classroom.  相似文献   

Extended Validation of the Korean Version of the Quality of Life Survey     

SeYun Park  Erin Reifsteck  Diane L. Gill 《Measurement in physical education and exercise science》2019,23(2):110-117

In this study, we examined the factor structure and reliability of the Korean Quality of Life (KQoL) survey and compared the KQoL survey to both the World Health Organization Quality of Life-Brief Version (WHOQOL-BREF) and the Satisfaction with Life Scale (SWLS). We also assessed associations between KQoL scores and physical activity (PA) participation. Participants were 557 (male = 281, female = 276) healthy Korean adults with ages between 18 and 71 years (M = 33.2, SD = 14.2). Results of confirmatory factor analyses confirmed the 7-subscale model and indicated acceptable values supporting convergent validity (χ² = 1,678.758, df = 443, p < .001, RMSR = .045, RMSEA = .071, TLI = .880, CFI = .892). Correlations of KQoL subscales with similar subscales of WHOQOL-BREF and with SWLS supported concurrent validity. Results confirm that the KQoL survey can assess multidimensional aspects of quality of life (QoL), including spiritual, physical, social, and psychological. KQoL scores were positively related to PA participation, in line with previous research supporting the positive association of PA with QoL.  相似文献   

Engagement with news on Twitter: insights from Australia and Korea     

Robert Ackland  Mathieu O’Neil  Sora Park 《亚洲交流杂志》2019,29(3):235-251

ABSTRACT

This study examines the patterns of news engagement among news consumers with different political affiliation and cultural background. We use computational methods and data from Twitter in a cross-country comparison of engagement with six online news sources in Australia and South Korea. For our analysis, we used a subset of Twitter users who retweeted at least one political story during the period of collection, and for whom we were able to predict political affiliation using correspondence analysis and data on Twitter follower ties to politicians. We find that right-wing Australian retweeters are more intense in their news engagement, compared with their left-wing counterparts, whereas in South Korea it was the opposite. Australian right-wing political retweeters have more diverse information sources, while there was no difference in information diversity between the right and left in South Korea. We discuss how the political situation in South Korea at the time of data collection may have affected our analysis. We emphasise the methodological contributions of our research and its connection to on-going research into the behavioural foundations of ‘filter bubbles’.  相似文献
