Feedback (F) Fueling Adaptation (A) Network Growth (N) and Self-Organization (S): A Complex Systems Design and Evaluation Approach to Professional Development     

Susan A. Yoon  Eric Klopfer 《Journal of Science Education and Technology》2006,15(5-6):353-366

This paper reports on the efficacy of a professional development framework premised on four complex systems design principles: Feedback, Adaptation, Network Growth and Self-organization (FANS). The framework is applied to the design and delivery of the first 2 years of a 3-year study aimed at improving teacher and student understanding of computational modeling tools. We demonstrate that structuring a professional development program around the FANS framework facilitates the development of important strategies and processes for program organizers such as the identification of salient system variables, effectively distributing expertise, adaptation and improvement of professional development resources and activities and building technological, human and social capital. For participants, there is evidence to show that the FANS framework encourages: professional goal setting, engagement in a strong professional community and personal autonomy by enabling individualized purpose—all fundamental components in promoting self-organization. We discuss three meta-level themes that may account for the success of the FANS framework: structure versus agency, exploration versus exploitation and short-term versus long-term goals. Each illustrates the tension that exists between competing variables that need to be considered in order to work effectively in real world complex educational systems.  相似文献

A cross-national analysis of election news coverage of female candidates' bids for presidential nomination in the United States and South Korea     

Youngmin Yoon  Yoomin Lee 《亚洲交流杂志》2013,23(4):420-427

This study has explored the US and Korean newspapers' election coverage in regard to their respective nations' female candidates relative to male rivals during the 2007–2008 presidential nomination campaigns. The findings reveal that both US and Korean newspapers displayed no bias in adopting personal, issue, and viability frames to cover the female candidates versus the male candidates. Additionally, the US dailies gave Clinton as much attention as Obama, as can be seen in the similar amount of articles, headlines, and primary coverage; however, Park, the female candidate in Korea, garnered a lower amount of articles and headlines, and was featured much less as the primary focus when compared to Lee, her male rival, in the Korean dailies. Evidence of biased coverage in the USA is found in the slant of coverage Clinton received. The overall tone of campaign coverage was less positive toward Clinton. While there was no tonal difference between Park and Lee in overall stories and headlines, the tone of Park's viability coverage was less positive than that of Lee, indicating that she was less likely to be the elected nominee for the party.  相似文献   

Testing Factorial Invariance in Multilevel Data: A Monte Carlo Study     

Eun Sook Kim  Oi-man Kwok  Myeongsun Yoon 《Structural equation modeling》2013,20(2):250-267

Testing factorial invariance has recently gained more attention in different social science disciplines. Nevertheless, when examining factorial invariance, it is generally assumed that the observations are independent of each other, which might not be always true. In this study, we examined the impact of testing factorial invariance in multilevel data, especially when the dependency issue is not taken into account. We considered a set of design factors, including number of clusters, cluster size, and intraclass correlation (ICC) at different levels. The simulation results showed that the test of factorial invariance became more liberal (or had inflated Type I error rate) in terms of rejecting the null hypothesis of invariance held between groups when the dependency was not considered in the analysis. Additionally, the magnitude of the inflation in the Type I error rate was a function of both ICC and cluster size. Implications of the findings and limitations are discussed.  相似文献   

A Field Test for Upper Body Strength and Endurance     

Jack K. Nelson  Seung H. Yoon  Karyn R. Nelson 《Research quarterly for exercise and sport》2013,84(4):436-441

Abstract

Historically, a measure of upper body strength and endurance has been included in fitness test batteries that are typically administered in the school setting. Pull-ups, or some modified form of pull-ups, have been the most popular test item used for the measurement of upper body strength and endurance. Despite the widespread usage of pull-ups, the test has often been criticized because of the large number of zero scores and the subsequent loss of discrimination among ability levels (Jackson & Griffin, 1983). The inability to achieve a score is perceived as failure on the part of the student.  相似文献   

The Challenges of Science Inquiry Teaching for Pre-Service Teachers in Elementary Classrooms: Difficulties on and under the Scene     

Hye-Gyoung Yoon  Yong Jae Joung  Mijung Kim 《Research in Science Education》2012,42(3):589-608

In the context of the emphasis on inquiry teaching in science education, this study looks into how pre-service elementary teachers understand and practise science inquiry teaching during field experience. By examining inquiry lesson preparation, practice, and reflections of pre-service elementary teachers, we attempt to understand the difficulties they encounter and what could result from those difficulties in their practice. A total of 16 seniors (fourth-year students) in an elementary teacher education program participated in this study. In our findings, we highlight three difficulties ‘on the lesson’ that are related to teaching practices that were missing in the classrooms: (1) developing children’s own ideas and curiosity, (2) guiding children in designing valid experiments for their hypotheses, (3) scaffolding children’s data interpretation and discussion and another three difficulties ‘under the lesson’ that are related to problems with the pre-service teachers’ conceptualization of the task: (4) tension between guided and open inquiry, (5) incomplete understanding of hypothesis, and (6) lack of confidence in science content knowledge. Based on these findings, we discuss how these difficulties are complexly related in the pre-service teachers’ understandings and action. Several suggestions for science teacher education for inquiry teaching, especially hypothesis-based inquiry teaching, are then explored.  相似文献   

Experiences With an Open Systems Computing Laboratory     

Bruce R. Maxim  Bruce S. Elenbogen  Kenneth L. Modesitt  David H. Yoon  Louis Tsui  Kiumi Akingbehin 《Computer Science Education》2013,23(2):247-256

Open Systems are computing systems which are based on industry standards and nonproprietary multivendor components. As an increasing number of computing installations move away from single‐vendor proprietary architectures to more and more open architectures, academic institutions are increasingly faced with the responsibility of appropriately introducing open systems concepts into the undergraduate curricula. Using funding from the National Science Foundation, an open systems computing laboratory was recently set up at the University of Michigan‐Dearborn. The laboratory is based on the three most popular computing platforms today in the PC to Workstation range; namely IBM/PC, Macintosh, and Sun/UNIX. Supporting equipment include a postcript printer, a Novell network, a tape mass storage, and appropriate software and interfaces. A three credit‐hour course titled Open Systems Computing was offered in Summer 1995 to computer science and computer engineering majors. The course utilized the laboratory fully. This paper describes the design and implementation of the laboratory. Initial experiences with the course and laboratory are also described. Student enthusiasm about the course and laboratory was much higher than anticipated. A side benefit of the course was the ability to introduce several contemporary computing‐related topics which would have otherwise been omitted from the curriculum.  相似文献   

Body-Mind-Spirit Practice for Healthy Aging     

Eun-Kyoung Othelia Lee  Hyunsook Yoon  Jungui Lee  Jiyoung Yoon  Eunjin Chang 《Educational gerontology》2013,39(7):473-485

This community-based, health promotion intervention for seniors provided a comprehensive review of the effect of body-mind-spirit (BMS) interventions on health behaviors. The 12-week curriculum offered sessions on exercise, nutrition, sexuality, leisure, stress management, cognitive behavioral therapy, forgiveness, and happiness. Gerontological experts carefully reviewed the adequacy of the program's objectives and instructional methods to meet the needs of older adults in South Korea. Seventy community-dwelling older adults were recruited at two community welfare centers and assigned to experimental (n = 32) and control (n = 38) groups. Extensive evaluations found that participation in the BMS program contributed to better outcomes in both physical and spiritual dimensions of health.  相似文献   

How does openness influence the impact of a scholar’s research? An analysis of business scholars’ citations over their careers     

Mustapha Belkhouja  Hyungseok Yoon 《Research Policy》2018,47(10):2037-2047

How do the effects of cognitive openness and structural openness on the research impact of business scholars vary over their careers? By analysing a longitudinal sample of 35,296 scholars who published in business and management journals, we show that the cognitive openness and the structural openness of business scholars have non-linear relationships with their research impact. In particular, we found that, whereas moderate levels of cognitive openness and structural openness are desirable for increasing young scholars’ citations, a high level of cognitive openness and a low level of structural openness contribute to senior scholars’ citations. This study contributes to our understanding of different search behaviour across business scholars’ career paths and its implications for scholars’ research impact.  相似文献
