In this autoethnography, I inquire into naming the histories and dynamics behind some of the embodied and affective experiences I have had as a Korean American woman of color while studying up/down, across/within, in White-dominant professional spaces such as K-12 schools. This ‘in-between’ status is part of the nature of being Korean American. In this inquiry, I draw on vignettes from my experiences in the field as an ethnographic researcher. These experiences form the heart of the paper in the form of epigraphs and narratives from experiences in multiple studies to capture the reverberations of fleeting moments – hauntings – that have accumulated over time. In doing so, I am joining existing conversations about Korean American women and about researcher reflexivity and positionality, bringing them together across time and space.  相似文献

This study investigated how Health Information National Trends Survey (HINTS) data from the U.S. National Cancer Institute (NCI) was cited in the scholarly literature. It addressed the following research questions: (1) What patterns of citations exist among authors of research articles using HINTS data? and (2) How is the citation format of HINTS data characterized? We collected scholarly articles that used HINTS data as primary or secondary data for analysis from Web of Science databases and HINTS publications on the NCI website. Among the resulting 250 articles, we identified citations to HINTS data themselves (data citations) and those to HINTS‐related documents (data‐related citations). Among the 250 articles, 156 articles (62.4%) cited HINTS data or HINTS‐related documents; only 29 articles (11.6%) cited HINTS data, while 127 (50.8%) cited HINTS‐related documents. Both data and data‐related citations increased over time. Data citation format varied, and 13 different compositions of citation elements were identified. Author, Title, and Location (URL) were common elements. The frequent use of URLs is undesirable due to URL instability. Furthermore, the data citations showed not only various compositions of citation elements but also ill‐defined element formats. Standardized citation formats are therefore needed.  相似文献

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

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 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

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

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

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
