Cumulative childhood trauma and psychological maladjustment of sexually abused children in Korea: Mediating effects of emotion regulation     

Ji Young Choi  Kyung Ja Oh 《Child abuse & neglect》2014

The purpose of the present study was to identify the mediating effects of emotion regulation on the association between cumulative childhood trauma and behavior problems in sexually abused children in Korea, using structural equation modeling (SEM). Data were collected on 171 children (ages 6–13 years) referred to a public counseling center for sexual abuse in Seoul, Korea. Cumulative childhood traumas were defined on the basis of number of traumas (physical abuse, witnessing domestic violence, neglect, traumatic separation from parent, and sexual abuse) and the severity and duration of traumas. Children were evaluated by their parents on emotion regulation using the Emotion Regulation Checklist and internalizing and externalizing behavior problems using the Korean-Child Behavior Checklist. SEM analyses confirmed the complete mediation model, in which emotion dysregulation fully mediates the relationship between cumulative childhood traumas and internalizing/externalizing behavior problems. These findings indicate that emotion regulation is an important mechanism that can explain the negative effects of cumulative childhood traumas and that there is a need to focus on emotion regulation in sexually abused children exposed to cumulative trauma.  相似文献   

Korean-American student perceptions on literacy and identity: perspectives from an ethnographic case study     

Jeonghee Choi  Heriberto Godina  Yeon Sun Ro 《Asia Pacific Journal of Education》2014,34(3):259-272

This ethnographic case study examines perceptions of literacy and identity for a Korean-American student in a third-grade classroom. The researchers examine how teachers can misinterpret Asian identity in the classroom due to perceptions related to the Model Minority Myth and other stereotypical representations of Asian culture. By focusing solely on academic success, teachers miss opportunities to gain insight for nurturing other areas of student success and adjustment in the classroom environment. Implications for identity formation and authentic integration of language and literacy practices are discussed. Educators interested in culturally-relevant instruction for immigrant students should find this study informative.  相似文献   

Development and Implementation of Science and Technology Ethics Education Program for Prospective Science Teachers     

Hyang-yon Rhee  Kyunghee Choi 《Science & Education》2014,23(5):1101-1130

The purposes of this study were (1) to develop a science and technology (ST) ethics education program for prospective science teachers, (2) to examine the effect of the program on the perceptions of the participants, in terms of their ethics and education concerns, and (3) to evaluate the impact of the program design. The program utilized problem-based learning (PBL) which was performed as an iterative process during two cycles. A total of 23 and 29 prospective teachers in each cycle performed team activities. A PBL-based ST ethics education program for the science classroom setting was effective in enhancing participants’ perceptions of ethics and education in ST. These perceptions motivated prospective science teachers to develop and implement ST ethics education in their future classrooms. The change in the prospective teachers’ perceptions of ethical issues and the need for ethics education was greater when the topic was controversial.  相似文献   

Developing Character and Values for Global Citizens: Analysis of pre-service science teachers’ moral reasoning on socioscientific issues     

Hyunju Lee  Hyunsook Chang  Kyunghee Choi  Sung-Won Kim  Dana L. Zeidler 《International Journal of Science Education》2013,35(6):925-953

Character and values are the essential driving forces that serve as general guides or points of reference for individuals to support decision-making and to act responsibly about global socioscientific issues (SSIs). Based on this assumption, we investigated to what extent pre-service science teachers (PSTs) of South Korea possess character and values as global citizens; these values include ecological worldview, socioscientific accountability, and social and moral compassion. Eighteen PSTs participated in the SSI programs focusing on developing character and values through dialogical and reflective processes. SSIs were centered on the use of nuclear power generation, climate change, and embryonic stem cell research. The results indicated that PSTs showed three key elements of character and values, but failed to apply consistent moral principles on the issues and demonstrated limited global perspectives. While they tended to approach the issues with emotion and sympathy, they nonetheless failed to perceive themselves as major moral agents who are able to actively resolve large-scale societal issues. This study also suggests that the SSI programs can facilitate socioscientific reasoning to include abilities such as recognition of the complexity of SSIs, examine issues from multiple perspectives, and exhibit skepticism about information.  相似文献   

Factors influencing the higher education of international students from Confucian East Asia     

Serene H.-J. Choi  Timo A. Nieminen 《高等教育研究与发展》2013,32(2):161-173

Higher education, especially that leading to a degree from a high-prestige university, is strongly related to social status and employment opportunities in East Asian countries. This is a consequence of both traditional Confucian attitudes to education and the social and economic changes accompanying industrialisation. Since the number of places available at high-prestige universities is limited, competition is intense. Successful entry to such a university is not only an important achievement for the future career of the student, but also a victory for the family. In contrast, failure to do so is often seen as shameful for the family, sometimes resulting in psychological problems or suicide. This background affects the international education of East Asian students, who often have a high level of family support, with correspondingly high expectations of their success. Motives for international study vary, from avoidance of the hyper-competitive domestic system, pursuit of an overseas degree as an ‘easy option’ of moderate prestige, to an expectation of more up-to-date teaching and content. Understanding this background can be a first step for Australian or other Western educators to better meet the needs of East Asian international students and to attract students from East Asia in the long term.  相似文献   

Reliable automatic word spacing using a space insertion and correction model based on neural networks in Korean     

Sihyung Kim  Gihyeon Choi  Harksoo Kim 《Information processing & management》2019,56(3):1046-1052

Automatic word spacing in Korean remains a significant task in natural language processing owing to the extremely complex word spacing rules involved. Most previous models remove all spaces in input sentences and insert new spaces in the modified input sentences. If input sentences include only a small number of spacing errors, the previous models often return sentences with even more spacing errors than the input sentences because they remove the correct spaces that were typed intentionally by the users. To reduce this problem, we propose an automatic word spacing model based on a neural network that effectively uses word spacing information from input sentences. The proposed model comprises a space insertion layer and a spacing-error correction layer. Using an approach similar to previous models, the space insertion layer inserts word spaces into input sentences from which all spaces have been removed. The spacing error correction layer post-corrects the spacing errors of the space insertion model using word spacing typed by users. Because the two layers are tightly connected in the proposed model, the backpropagation flows are not blocked. As a result, the space insertion and error correction are performed simultaneously. In experiments, the proposed model outperformed all compared models on all measures on the same test data. In addition, it exhibited reliable performance (word-unit F1-measures of 94.17%～97.87%) regardless of how many word spacing errors were present in the input sentences.  相似文献   

Improving Item-Exposure Control in Adaptive Testing     

Wim J. van der Linden  Seung W. Choi 《Journal of Educational Measurement》2020,57(3):405-422

One of the methods of controlling test security in adaptive testing is imposing random item-ineligibility constraints on the selection of the items with probabilities automatically updated to maintain a predetermined upper bound on the exposure rates. Three major improvements of the method are presented. First, a few modifications to improve the initialization of the method and accelerate the impact of its feedback mechanism on the observed item-exposure rates are introduced. Second, the case of conditional item-exposure control given the uncertainty of examinee's ability parameter is addressed. Third, although rare for a well-designed item pool, when applied in combination with the shadow-test approach to adaptive testing the method may meet occasional infeasibility of the shadow-test model. A big M method is proposed that resolves the issue. The practical advantages of the improvements are illustrated using simulated adaptive testing from a real-world item pool under a variety of conditions.  相似文献   

The rise of the organisational society in Canadian and U.S. textbooks: 1836-2011     

Minju Choi  Nadine Ann Skinner 《Globalisation, Societies & Education》2021,19(1):7-22

ABSTRACT

This paper examines how organisations have increasingly been portrayed in textbooks as solving social problems as well as contributing to national development. Findings from 527 Canadian and U.S. textbooks illustrate the rise of an organisational society during the time period between 1836 and 2011. Discussions of for-profit and non-profit forms of organisations rise early on in both countries, creating the foundation for an organisational society, which expands to incorporate global organisations in the post-World War II period. We argue that such portrayals in textbooks both reflect and legitimise the role of organisations in society, strengthening their taken-for-granted status as social actors.  相似文献   

Practitioners’ celebrity endorser selection criteria in South Korea: an empirical analysis using the Analytic Hierarchy Process     

Bongchul Kim  Hana Kim  Myungil Choi 《亚洲交流杂志》2017,27(3):285-303

This study investigated how clients and advertising agencies in Korea prioritized celebrity selection criteria differently. Responses from 50 client-side and 50 agency-side executives in Korea were analyzed using the Analytic Hierarchy Process. Results show that the brand-centered factor ‘Match-up’ was considered most important by both clients and agencies but that the celebrity-centered factor ‘Popularity’ was ranked quite differently (i.e. second by agencies and fourth by clients, out of five factors). Other factors (i.e. Availability and Potential Risk) were ranked similarly. The main finding of the study is that Korean ad agencies and clients placed different weight on celebrity endorser selection criteria. This finding is particularly valuable to national and international advertisers who are deliberating about celebrity endorsement for the Korean market.  相似文献   

Political Discussion,Political News,and Internet Use: Factors of Media Trust in South Korea     

Hyunjung Kim  Yoon-jung Choi 《Communication Research Reports》2017,34(3):211-220

This study examines political and communicative factors predicting trust in mainstream newspapers and television by analyzing a set of survey data collected in South Korea. The results show that supporters of the opposition party are less likely to trust the mainstream news media than supporters of the ruling party. Daily Internet use negatively predicted trust in media only for nonpartisans. However, for supporters of the opposition party, daily Internet use moderated the interaction effect between political discussion and exposure to political news on trust in media.  相似文献
