We studied the effects of science high school students on the change of epistemological beliefs in chemistry and the academic achievement of chemistry by completing 'advanced chemistry'. For seven months from July 2023 to January 2024, 80 first-year students at G Science High School in Gyeongnam were surveyed and analyzed for epistemological beliefs about chemistry before and after classes in advanced chemistry. Chemistry academic achievement was classified by 'upper' and 'lower' levels based on the end-of-semester grades of 'advanced chemistry' in the second semester of the first year and analyzed with the SPSS 28 program. After completing advanced chemistry, the epistemological belief in chemistry increased in the proportion of favorable responses. After completing advanced chemistry, the proportion of favorable responses increased in detailed factors such as 'effort', 'math link', 'outcome', 'reality link', and 'concepts', while the 'visualization' factor decreased. Although completing 'advanced chemistry' positively changed students' epistemological beliefs about chemistry, visual expression showed little contribution to understanding chemical concepts. Based on the above results, we will have to focus on the design of instructors' teaching-learning, such as learner-centered inquiry experiments, creative visual expressions, etc., for successful chemistry teaching-learning.

The educational policy of a nation should be based on the results of nation-wide studies and their analyses. This study is the third one in a series of research on "development of improvement plan and monitoring system for secondary school science", focusing on the three major areas, such as students' achievements, science instruction and conditions for science education in vocational high schools. In general, the results showed that science achievements in vocational high schools were significantly lower than those of general high schools. While the achievement level in physics was lower by one percent, the achievement levels in chemistry and biology were significantly lower by more than 5 percents. In the case of scientific inquiry, the results showed much lower scores compared to those of general high schools. Concerning the inquiry abilities, most of the students did not possess the formal operational thinking skills such as controlling variables and combinatorial thinking. The ability of experimental skills seemed to be closely related to the students' majors. Students in industrial arts schools could measure electric resistance very well, while students in agricultural high school students failed completely. In the area of students' attitude toward science, the greater part of the students had the experiences of using scientific equipments (68.6 %), experimentation (54.3 %), and extracurricular science activities (56.9 %). They also showed positive attitude towards the nature of science (59.8%). The results of the survey on science instruction and school conditions for science education showed the needs for improvement In general, the priority of science education in vocational high schools was very low compared to their major subjects. The teachers as well as students thought science text books nor to be difficult These responses and the low achievement levels seemed to be contradictory to each other. The facilities for science experiments were better equipped and installed to general high schools. However. the lack of budget was a major problem for performing experiments uning the facilities. Therefore. science education in vocational high school have many things to be improved For the improvement of science education in vocational high schools, financial support as well as the intention for the improvement must be the essential factors.

The purpose of this study is to obtain science high school students' perceptions of scientists and their work before and after the Green Investigation program with scientists. This study also attempts to determine whether the program affected the participants' perceptions of scientists and their work. A modified DAST was carried out with 64 high school students. Findings revealed that Korean science high school students had normal perceptions of scientists, such as images of 20 to 30 year old males wearing laboratory coats and working alone in research labs with test tubes, flasks, and several machines in the background. After the intervention, students drew fewer typical items representing scientists and had significantly different perceptions of their work places between the pretest (M=1.69, SD=1.14) and posttest (M=1.96, SD=1.24, t=4.43, p<0.001) with the eta squared statistics (.24). These findings reflect the need for continued efforts of developing green investigation programs with scientists for students. Some future studies based on this study are also introduced.

The purpose of this study was to analyze high school students' school uniform wearing attitude by group according to clothing attitude targeting Gyeongnam area. This study aims to provide preliminary data in the field of school uniform and marketing that clothing propensity by groups is considered. This study conducted a survey targeting 762 high school students in Gyeongnam. For statistical analysis, SPSS for Window 14.0 was used for frequency analysis, factor analysis, reliability analysis, multiple sponse analysis, cluster analysis, ANOVA analysis and Duncan's ex-post analysis method. As a result of cluster analysis on the clothing attitude, students were divided into 4 segmentation of fashion seeking group, fashion indifference group, conformity group and modesty group. As a result of verification on the difference in perception toward wearing school uniform by groups which were classified according to the propensity of clothing attitude, activity, stability, and practicality were all varied according to the propensity of clothing attitude. 4 groups were significant differences in the degree of consent to wearing school uniform, price of school uniforms, tendency to prefer famous brand when purchasing school uniform, experience of transforming school uniform, opinion about school uniform modification and reason for school uniform modification. While low graders were many in 'modesty group', upper graders were many in 'fashion seeking group', which means that more segmentalized satisfaction of clothing by group may be raised if such a fact is considered when planning clothing for high school students segmentalized by age.

Purpose: The aim of this study was to describe the status and associated factors of mental health on girls' high school students. Methods: The participants were 446 academic girls' high school students and 240 vocational girls' high school students of the 1st graders in Busan. The data were collected from April 28, 2009 to May 30, 2009. Survey was developed in the form of self-report five-point likert scale(1-5) using Lees Instrument of mental health(1986) that revised from Derogatis et al's Symptom Check List-90(1976). The higher score of this scale means worse status of mental health. Result: The score of mental health of subjects was low and the mean was $1.69{\pm}.50.$ The depression mean was the highest among mental health sub-variables. The mental health of the vocational girls' high school students was worse than the academics. As for subjects in mental health by their various characteristics, there are significant by school type(p<0.001), economic status(p<0.001), father's job(p<0.001), parent's marrital status(p<0.001), cognitive health status(p<0.001), record(p<0.05), character(p<0.001), satisfaction of life(p<0.001), needs for help on mental health(p<0.001). Conclusion: The intervention program needs to improve mental health of vocational high school girls' students as well as academic high school girls' students, and need to establish depression relieving nursing intervention program for girls' high school students.

The purposes of this study was to investigate high school girl students’concerns about the family life education in Home Economics and their needs for learning in home economics classes in order to develop an advisable co-education curriculum. The questionnaires were completed by 196 first grade students in Seoul in 1993 and 765 first grade students in Tokyo and Kanagawa Prefectures in 1991. The contents of the questionnaire were as follows：1) students’interests in the areas of Home Economics education, 2) students＇concerns in their daily life 3) students’interests in a new curriculum for family life education：16 contents from human birth to death. 4) students’experience with their family, and 5) students’educational needs in Home Economics’teaching method. The result of our research showed that：1) Most of senior high school students in Korea and Japan had strong interests in their life and life span. 2) Although there are some differences in the degree of concerns between Korea and Japan, senior high school students in Korea and Japan had strong concerns with their “characteristics and personality”, their “future job”, their “looks and figure”and their “hobby and amusement”, these had not been the contents of home economics in Korea and Japan, but had been in U.S. 3) Very few senior high school students in Japan and especially in Korea had contacts with their grandparents. 4) Senior high school students in Korea and Japan showed strong interests in their near future stage, but they showed less interest in the stage of early childhood. 5) Senior high school students in Korea and Japan showed their diverse needs for learning in home economics classes. The results indicated that co-education curriculum for family life education should meet adolescent needs and concerns, and our new curriculum, “from one’s birth to death/one’s life span”, would be more advisable.

The aims of this study are to investigate how Kepler found a scientific problem for the retinal image theory and to investigate how the science high-school students respond when the same situation is applied to them. And their results was compared with general high-school students' results. Kepler found the scientific problem in the eye vision through the critical analysis of contemporary theories of vision, based on his relevant knowledge of optics. When we applied the same situation to the Korean science high school and general high-school students, only a few of science high-school students found the scientific problem as same as Kepler's finding. From the results, it is suggested that in development of creativity teaching material, the situations like Kepler's problem finding need to be included in the programs.
