The purpose of this study was to apply machine learning techniques (Decision Tree, Random Forest, XGBoost) to data from the 4th~6th year of the Seoul Education Longitudinal Study to find the factors predicting the career maturity of middle school students in Seoul city. In order to evaluate the machine learning application result, the performance of the model according to the indicators was checked. In addition, the model was analyzed using the XGBoostExplainer package, and R and R Studio tools were used for this study. As a result, there was a slight difference in the ranking of variable importance by each model, but the rankings were high in 'Achievement goal awareness', 'Creativity', 'Self-concept', 'Relationship with parents and children', and 'Resilience'. In addition, using the XGBoostExplainer package, it was found that the factors that protect and deteriorate career maturity by panel and 'Achievement goal awareness' is the top priority factor for predicting career maturity. Based on the results of this study, it was suggested that a comparative study of machine learning and variable selection methods and a comparative study of each cohort of the Seoul Education Termination Study should be conducted.

This is a pilot study of multifaceted longitudinal research project to explore educational experiences of students with multicultural family backgrounds in Korea. Especially for this pilot study, I selected three foreign-born immigrant youths and tried to explore how these youths describe constraints of their learning experience in different culture. The data for this study were mainly collected through qualitative research methods. For a better understanding of the research participants' perceptions in this study, narrative inquiry and series of semi-structured in-depth interviews were conducted for a period of four months which corresponds to one semester of school system in Korea. As a result, this study found that there is an urgent need to establish a systemic and developmentaly appropriate language education programs that ensure educating the language to the foreign-born immigrant youths because their academic achievement, interpersonal relationships, and future depend greatly on the fluency of Korean language. It was also found that it is necessary to take appropriate educational actions in supporting alternative schools where the foreign-born immigrant youths can fully and seriously considered as a whole person. Although this study has some limitations in examining every single aspect of the current state of education of students with multicultural backgrounds in Korea, it provides deep insight into some of their initial educational experiences and proposes several ways to improve these educational programs for them.

This qualitative study explores how Mongolian migrant workers, with a marked tendency for family migration, plan and put into practice their child's education and attach meaning to it in relation to the social network they form during their stay in Korea. Specifically, it analyzes in particular ways the social network Mongolian migrant workers form affect their settlement in Korea, the process by which the social network affects their planning of their child's education, and how the education planning and its realization lead to the formation of new social networks. The results show that parents were divided between those who made a deliberate decision in sending their child to the Seoul Mongol School as a part of their plan and those who chose the school due to forced circumstances. While some parents preferred the Seoul Mongol School over regular Korean schools for their child's education and future, others sent their child to the Seoul Mongol School, regardless of their preference, because they did not have access to information about regular Korean schools, were afraid of divulging their illegal status, or were afraid their child would not be able to adjust to the school life in Korean schools. Based on such analysis, this paper stresses the urgency of further research in this area, and suggests direction for future policy measures.

The study was aimed to find out whether there are differences in perception toward multicultural youth's career problems according to the four stages of life cycle(adolescence, pre-marriage, family formation child rearing), and multicultural families and non-multicultural respondents. Also is was aimed to find out if there is an interactive effect on problem recognition. A nationwide survey was conducted using questionnaire on the perception of multicultural youth careers and a total of 1,338 responses were used for the final analysis. For the research purpose, a two-way MANOVA was performed. First it was found that multicultural family members had higher negative perceptions of multicultural appearances than non-multicultural family members had and the adolescents had relatively low negative perceptions of personal relationships and social life adaptation of multicultural youth. Also, as a result of examining whether there is an interaction effect on perception of career problems of multicultural adolescents between multicultural families and their life cycle stages, interaction effects existed in all aspects of family environment, career activities, education, and institutions. It has been shown that there are differences in the perception of career issues among members of multicultural families or among non-cultural families.

This research investigates gifted students' mothers' rearing stress based on the concept mapping method. For this, 12 gifted students' mothers solicited, gathered and analyzed related statements, and then did multidimensional scaling and hierarchical cluster analysis. The stress value was .273 which was appropriate for the two level concept mapping study. In addition 101 mothers of gifted students rated for the rearing stresses they experience. Results were as follows. First, 79 concrete statements were solicited and as a result of concept mapping were categorized as 'burden and conflict as mothers of the gifted', 'possible negative characteristics due to the giftedness', and 'self-esteem and pressure by the title of the gifted'. Especially following items showed relatively high average: worrying about how to give the child a specific help for his/her career(M=4.65); worrying that she might be intervening too much in their child's behaviors(M=4.60); getting pressured supporting the child to get involved in the gifted education system continually(M=4.46); worrying if her child is not developing his/her talent enough due to the lack of time and money(M=4.44); being concerned that her high expectations might be putting her child under too much pressure (M=4.43). Implications of the study related to gifted education practices were discussed.

This study analyzed the differences in parents' perceptions toward children's adjustments after grade skipping and early graduation. Parents of an early entrancer to K university(n=43) and parents of a non-early entrancer to K university(n=12) responded two kinds of questionnaires, one is for parents' perceptions towards children's needs for grade skipping and early graduation, and the other is for parents' perceptions toward children's adjustments to university experiences. Parents' responses were analyzed by MANOVA and MANCOVA. Results indicated that there was the significant difference in parents' perceptions for 'information about early graduation.' That is, parents of an early-entrancer had more 'information about early graduation' than their counterparts. However, there was no significant difference in parents' perceptions, after the effect of 'information about early graduation' on parents' perceptions toward children' academical and social-emotional adjustments. Thus, parents having more 'information about early graduation' considered more seriously the needs of grade skipping and early graduation in their children and worried less about their children's adjustments to university experiences.

The purpose of this study is to qualitatively investigate how career women form their self-identity in relationship to their parents from the viewpoint of life-span development, and to provide practical information helpful for understanding the change of relationship between parents and adult children and forming desirable parents-daughter relationships by developing the substance theory which suits the socio-cultural context of Korea. In this study, 24 unmarried women who have parents and engage in professional jobs were selected for an in-depth interview. From the findings of this study, 67 concepts, 29 subordinate categories and 13 categories were extracted during the process of open-coding; a research model was then constructed according to the paradigm of the grounded theory. It was found that there are three types: the reality-convinced type, the conflict-compromising type and the self-regulated type who "persistently worry about themselves and try to develop". These results verify the process of career women "worrying about themselves and developing constantly" and its structure by forming their self-identities, adjusting the effects of several contextual factors and using mediatory strategies in the developmental process of self-identity.

This study examined the structural relationships among parental attitudes and expectations toward mathematics, mathematics motivation and achievement of their child in PISA 2012 of South Korea. Data were analyzed using structural equation modeling(SEM) analysis. The results were as follows: First, parental attitudes toward mathematics had positive effects on parent academic and professional expectations in mathematics. Second, parental expectations also had positive effects on intrinsic motivation, instrumental motivation and math achievement for their child. Third, instrumental motivation had strongest effects on math achievement. The next factors which had effects on math achievement were intrinsic motivation and parental expectations in order. This results shows that the parental awareness of the usefulness and necessity of mathematics will help to increase the interest and value toward mathematics, math achievement and interest of math related carriers of their child.
