We investigated South Korean workers’ reflections on career chance events in terms of types of chance occurrences and factors that influence how these are reacted to. A critical incident technique was used to collect data from 85 participants using an open-ended questionnaire. Various types of events that happened unexpectedly were identified through a two-dimensional framework: whether an event was relationship based or experienced based, and whether it occurred in personal areas or work areas. Influencing factors that affected the participants’ reactions were also categorized using a two-dimensional framework: internal or external, and facilitating or discouraging dimensions.

Mobile devices are highly portable, easily distributable, substantially affordable, and have the potential to be pedagogically complementary resources in education. This study, incorporating mixed method analyses, discusses the implications of a mobile learning technology-based learning model in two public primary schools near the Mexico-USA border in the state of Baja California, Mexico. One school was located in an urban slum and the other in a rural village community. Empirical and ethnographic data were collected through a series of achievement tests, observations, surveys, and interviews involving 160 s grade school children recruited by convenience sampling. The general technology infrastructure, distinctive features of mobile learning to supplement literacy development, profound contextual phenomena arising from the two uniquely underserved communities, and social factors possibly influencing the educational experiences are discussed. The findings suggest that students in the rural village, seriously lacking educational resources and technology exposure, may have benefited substantially more from mobile technologies than urban school students possibly due to their relatively higher socio-economic status and higher parental involvement and interest in education. In contrast, there was no evidence of interaction with parental education levels, the experience of teachers or school principals, or the teacher’s perception or preparation of the technology. Overall, the mobile learning technology adoption was rapid, seamless, and actively driven by the students rather than the teacher. The challenges of the phenomenal migratory nature of most families in this unique geographical region are also discussed to benefit future studies.  相似文献

This study examines what a Korean heritage language school means to Korean immigrant families and their children, considering Korean immigrant mothers’ perspectives on American early schooling. As part of an ethnographic research project on Korean-American children’s peer culture in a heritage school, seven mothers, two guardians (grandmothers), and their young children were observed and interviewed during one academic year. The analysis showed that the heritage language school functions as a social and emotional support system, a buffer for reducing the detachment from parents, and a safety net for the Korean-American children’s challenging lives. The Korean immigrant mothers also showed that they felt burdened by different cultural views of their children’s behaviors, and described how their children were often considered problematic. The social and culture barriers caused by their immigrant status profoundly influenced their reasons for sending their children to a Korean heritage language school. This study suggests that teachers’ deep understanding of culturally different perspectives on children’s behaviors, along with systematic social and emotional support, can help these children attain psychological well-being.  相似文献

Part II of “Reclaiming Kindergarten” continues the discussion related to responding to the crisis in today’s kindergarten. In Part II, two policy questions are posed, the answers to which seek to respond to this continuing crisis. The questions center on issues related to engaging families in kindergarten and the need to consider a new early childhood paradigm where kindergarten is part of a continuous and seamless educational experience spanning prekindergarten through third grade. As in Part I, examples of classroom practice are used to illustrate the effective implementation of these principles in a kindergarten classroom.  相似文献

Attention-deficit/hyperactivity disorder (ADHD) and learning disabilities (LD) are the most commonly diagnosed childhood disorders, and they frequently co-occur with each other. It has been found that students with comorbidity of ADHD and LD experience more difficulties in school. Even though the research interests in the comorbidity of ADHD and LD are increasing, there are inconsistent results in research studies and insufficient understanding of the comorbidity of ADHD and LD. This study attempts to grasp the progress of the studies in the comorbidity of ADHD and LD in Korea and to suggest the future directions for following research. A total of 90 studies published between 1987 and 2009 are examined. First, we analyze the studies that examined the learning problems of ADHD and then identify the characteristics of the learning problems in ADHD group. Afterwards, we investigate the studies that dealt with the attention problems of LD and then discuss the characteristics of the attention problems in LD group. Third, we identify the differences between ADHD and LD and synthesize the research findings. Finally, we analyze the studies conducted in conjunction with the comorbidity of ADHD and LD. On lightening the research of the comorbidity on three aspects, we find the research trend in Korea and provide the implications for future studies on the comorbidity of ADHD and LD. Furthermore, we suggest that it is important to identify comorbid conditions at the early stage, and it is necessary to conduct multidisciplinary research and international comparison research.  相似文献

The authors evaluated an unfolding case‐based approach to a practicum in counseling course infusing crisis, trauma, and disaster preparation for changes in students’ crisis self‐efficacy across a semester. The course, informed by constructivist‐developmental pedagogy and centered on the unfolding case, resulted in significant increases in students’ crisis self‐efficacy.  相似文献
