This study analyzed the characteristics of National Science Curricula in the UK, Australia, New Zealand, Canada, Singapore, and Korea with respect to core competencies. In the case of overseas countries, literature review on their curricula was conducted, and four common features were extracted: 'association of cross-curricular competencies with science-specific competencies', 'a combination of science contents and scientific practices', 'an emphasis on communication skills', and 'representation of an achievement level of competency'. In addition, the common core competencies of science education were 'critical thinking', 'creative thinking', 'problem solving', 'inquiry skills', 'communication skills', 'cultural literacy', 'ability to integrate discipline', 'application skills', and 'personal/social competency'. In relation to these features, this study also investigated Korean science teachers' perceptions of core competencies in science education. A survey was conducted on 135 teachers in elementary, middle, and high school in Korea. Teachers were not well aware of what core competencies are, and after introduction, they thought that they wanted to and needed to teach core competencies to their students. Teachers claimed that critical core competencies in science education are 'creative thinking', 'problem solving', and 'inquiry skills'. Teachers thought that core competencies-based science class would help develop students' scientific literacy and communication skills. However, they have difficulties in conducting core competencies-based science class because they are not familiar with how to conduct the class and they expect that it will take a long time to prepare such a class.

The new paradigm of the 21st Century science education explores a wide range of possibilities that can foster students' interest toward science and creative convergence thinking. In this study, through the analysis of programs that were developed in 'STEAM leader school' and 'STEAM teacher association for research' supported by the 'Ministry of Education, Science, and Technology,' we analyzed the linking frequency with each of STEAM education's fields and teachers' perception for the convergence strategy of technology and engineering. The results of this study show that linking frequency of technology and engineering is lower than the field of arts and mathematics in elementary school, but higher in middle and high school. 'Introduction technology contents in lives' in technology and 'crafts activity' in engineering are the most used teaching and learning strategy in STEAM education. But, although 'crafts activity' is engineering's major way of learning, many teachers understand and use it as a technological teaching learning strategy. It is important to understand that each of STEAM education's field has a unique nature and educational implications, for the effective settlement of STEAM education, we need to consider teaching and learning strategy in various way.

The purpose of this study was to investigate the relationship between career barrier and career maturity of the adolescents who were concretely worried about their career and occupation. 672 middle school students were participated to analyze the Pearson Correlation and Multiple Regression Analyses with data collected by the questionnaire. This study revealed the following results. First, the correlational analysis showed that career barrier associated negatively with career maturity. Second, the multiple regression analysis revealed that sub-elements of career barrier which the adolescents conceived, such as the shortage of self-understanding, the shortage of self-reliance, gender-role conflict and gender discrimination, and the shortage of career and occupational information were significantly effecting their career maturity. Third, as a result of multiple regression analysis to estimate the explanability of career barrier on career maturity, career barrier among various independent factors which were correlated statistically with career maturity showed most effects on it. Also, school academic achievement was confirmed as a significant factor effecting the career maturity. Above these results imply that the perception on the career barrier of the adolescent should be reduced for increasing the career maturity. For this, career education and counselling should be positively intervened and reinforced through the school curriculum and activities.

This study evaluated the perception, school stress, psychological factors, and association of students in middle and high school groups in terms of their BMI (Body Mass Index). The '2010 Korea Youth Health Survey 'was used to study data 7187 people. The subjects were classified into the underweight group (BMI < 20), normal group (BMI 20 - 24), overweight group (BMI of 25-29), and obese group (BMI of 30 or higher). The subjects found to have experienced smoking were as follows: underweight BMI group (17.2%), normal weight group (18.4%), overweight group (21.8%), and obese group (25.8%) (p=0.016). The level of satisfaction was as follows: $14.24{\pm}3.15$ for the normal weight group, $13.67{\pm}3.13$ for the overweight, and $12.84{\pm}3.72$ in the obese group. The normal-weight group had a higher level of satisfaction (p=0.005). Underweight, normal, overweight, and obese BMI group were at school for an average of $33.57{\pm}5.76$, $33.45{\pm}5.50$, $33.12{\pm}5.34$, and $32.21{\pm}7.43$ hours per week, respectively (p=0.044). Therefore, the development of social misfit youths needs to be managed properly and effectively to improve their physical and mental health. Industry, academia and government need to collaborate with programs to achieve this aim.

This study reveals the aspects of subjectivity in the test results in a science-specific aspect when assessing science-related affective characteristic through self-report items. The science-specific response was defined as the response that appear due to student's recognition of nature or characteristics of science when his or her concepts or perceptions about science were attempted to measure. We have searched for cases where science-specific responses especially interfere with the measurement objective or accurate self-reports. The results of the error due to the science-specific factors were derived from the quantitative data of 649 students in the 1st and 2nd grade of high school and the qualitative data of 44 students interviewed. The perspective of science and the characteristics of science that students internalize from everyday life and science learning experiences interact with the items that form the test tool. As a result, it was found that there were obstacles to accurate self-report in three aspects: characteristics of science, personal science experience, and science in tool. In terms of the characteristic of science in relation to the essential aspect of science, students respond to items regardless of the measuring constructs, because of their views and perceived characteristics of science based on subjective recognition. The personal science experience factor representing the learner side consists of student's science motivation, interaction with science experience, and perception of science and life. Finally, from the instrumental point of view, science in tool leads to terminological confusion due to the uncertainty of science concepts and results in a distance from accurate self-report eventually. Implications from the results of the study are as follows: review of inclusion of science-specific factors, precaution to clarify the concept of measurement, check of science specificity factors at the development stage, and efforts to cross the boundaries between everyday science and school science.

The main purpose of this research is to investigate Korean adolescents' perception of stress experiences, and related social support. To this end, adolescents were asked about stress events, as well as stress symptoms, in their lives. Also, the adolescents were asked about the people that provided social support and the types of social support provided. The participants were 952 Korean adolescents (Primary 219; Middle 280; High 212; University 241). Among the four measures (stress events, stress symptoms, social supporters, and types of social support), the measure of stress symptoms yielded a reliability of Cronbach α=.88, while the remaining three measures yielded an inter-judger reliability of 89.6%, Kappa=.87. The results were as follows. First, for stress events, the most frequent responses were related to Academic Achievement, followed by Career/Job, Family Relations, Friend Relations, Lack of Capacity, and Financial Difficulties. For high-school students the most frequent responses were related to Academic Achievement, while for university students Career/Job. Second, for stress symptoms there were significant differences among the groups, in that the high-school students showed the highest level of symptoms, while primary school students the lowest. Third, for social supporters, the most frequent responses were related to Friends, followed by Myself, Parents, Teacher, Siblings, and Seniors/Juniors. As the groups aged (from primary to university), support from Friends and Seniors/ Juniors increased, while support from Parents decreased. Fourth, for the types of social support, the most frequent responses were related to Emotional Support, followed by None, Advice, Supporter Directly Solved Problem, and Talked with Me. The highest frequencies of responses were found for Emotional Support among all groups. As the groups aged (from primary to university), Advice increased while Supporter Directly Solved Problem decreased.

This study examined preferences for the clothing and textiles section of 'Technology and Home Economics' course, comparing males to females, and subdividing three groups based on the preference of the clothing and textiles section: a high-preference group, a medium-preference group, and a low-preference group. Their perceptions of the section. need to study, level of practice of teamed content, and learning needs were compared between males and females and among the three sub-groups. The subjects of this study were 176 male and 176 female high school students in Seoul. Data were collected using questionnaires with a 5-plint scale in September, 2004. Finally, 352 questionnaires were analyzed by the SPSS program. The results showed that all preferences for the clothing and textiles section were average and girls' preferences were higher than boys' preferences. General perceptions of the clothing and textiles section were positive, and there were no significant differences by gender. The perceptions of the high-preference group were more positive than those of the other two groups. The perceived importance of studying was high. especially with respect to clothing care and storage. Girls reported a greater need to study than boys did. Among both boys and girls, the high-preference group reported a greater need to study than the middle and low-preference groups did. The level of practice of learned content was leo, except for contents related to attire and the purchase of clothing. Girls practiced contents learned about attire more than boys did. Among boys, the high-preference group practiced contents teamed in all areas more than boys in the other two groups. However, among girls. only content related to attire was preferentially practiced by the high-preference group. Both boys and girls exhibited tile greatest learning need for fashion coordination. Girls had more learning needs than boys in all contents, except for clothing and environment. Among all students, the higher the level of preference, the higher their learning needs.

The purpose of this study was to examine the mediating effect of self-efficacy moderated by social support in the influence of local children's center cultural program commitment on career awareness and development of children and adolescents using Local Children Centers' Services. For this purpose, the questionnaires of local children's center cultural program commitment, career awareness and development, social support, and self-efficacy was conducted to 190 elementary school students in the 3rd grade and middle and high school in 22 children's centers in N city. The statistical packages were SPSS PC+ 25.0 and SPSS MACRO. The main results are as follows: First, cultural program commitment had positive correlation with self-efficacy, social support, career awareness and career development. Also, self-efficacy had a positive correlation with social support, career awareness and career development, and social support had a positive correlation with career awareness and career development. Second, the hypothesis model was supported that cultural program commitment positively affects career awareness mediated by self-efficacy moderated by social support. In other words, the more they participated and commited in cultural programs, the more self-efficacy increased leading to more career awareness. Also, the more social support was felt, the more the positive influence of cultural program commitment on self-efficacy increased. The hypothesis model was supported that cultural program commitment positively affects career development mediated by self-efficacy moderated by social support. In other words, the more they participated and commited in cultural programs, the more self-efficacy increased leading to more career development. Also, the more social support was felt, the more positive influence of cultural program commitment on self-efficacy increased. The limitation and future tasks were discussed.

Mathematics textbooks as the main resources to support mathematical teaching and learning are used importantly in Korean lessons. Although the scope of mathematics textbook research has been expanded and the research has increased, few studies have analyzed the overall trends of mathematics textbook research in Korea. This study analyzes the overall trends of textbook research on 418 papers pertinent to mathematics textbooks published in domestic mathematics education journals. The results of this study showed that the proportion of textbook analysis research was the highest, followed by textbook use and textbook development research in order. There were more textbook studies at the elementary school level than at the middle or high school levels. Regarding textbook analysis studies, the most frequent topic was to analyze how specific mathematical concepts were presented in textbooks. Regarding textbook use studies, many studies asked both teachers and students to review the appropriateness of textbooks under development or analyzed the perception and use of specific activities of textbooks based on a survey. Regarding textbook development studies, the most popular topics included the directions and examples of new development, such as storytelling-based or electronic textbooks. This paper finally presented implications for textbook research in light of the domestic mathematics education context and the international mathematics textbook research trends.

The purpose of this study was to investigate the BMI, dietary behaviors, body satisfaction and factors affecting the weight control interest according to gender of middle school students (195 boys and 251 girls) in Wonju area. The average height and weight of the boys were $164.8{\pm}8.3\;cm$ and $55.5{\pm}12.3\;kg$ respectively. Those of the girls were $158.8{\pm}5.0\;cm$ and $48.7{\pm}7.4\;kg$ respectively. The average body mass index (BMI) of the boys and girls was 20.3 and 19.3 respectively. In both boys and girls, 69.7% of them had regular meals and the main reason for skipping meals was insufficient time to eat due to oversleeping (33.6%). Most of the subjects consumed snacks more than once a day (95.5%). The dietary intake attitude score of the girls ($35.08{\pm}5.91$) was higher than that of the boys ($33.81{\pm}5.45$) (p<0.01). The eating disorders score of the girls ($12.92{\pm}6.22$) was higher than that of the boys ($10.70{\pm}9.82$) (p<0.01). Also, 87.2% of the subjects showed normal behavior and 12.8% of the subjects had eating disorders, but there was no significant difference according to gender. The body satisfaction score of the boys ($30.16{\pm}5.08$) was higher than that of the girls ($28.00{\pm}5.52$) (p<0.001). In general, body satisfaction score correlated positively with dietary intake attitude score, but correlated negatively with eating disorders score (p<0.05). Multiple regression analysis revealed that body satisfaction score was the most significant variable which affected the weight control interest. Therefore, development of the nutrition education program for adolescents will be effective not only for the improvement of dietary behaviors but also for the positive change in the misleading perception about the ideal body shape.
