The purpose of the study was to investigate the change of students' conceptual structures about sedimentary rocks through the field trip. A semantic network analysis method was utilized to assess the change. An open-ended questionnaire was developed to assess high school students' knowledge of sedimentary rock including its definition, classification, formation process, and characteristics. Fifteen high school students participated in the field trip of this study. The text data were analyzed using the semantic network analysis method. Results are as follows. First, high school students' conceptual structures about sedimentary rocks were more expanded after the field trip. Second, students' conceptual structures formed a 'small world network' by combining the sub-clusters. Third, the size of students' conceptual structures was decreased after a few month of field trip. Nonetheless, the connection among the clusters remained the same.

This study was to investigate the eating attitutes, food habits, perceived stress of high school students. Three hundred and fifty four high school students in Seoul area were surveyed to obtain the information from Sep. 18 to 26 in 1997. The average height and weight of high school students were 173.7 cm, 62.9 kg for male students and 162.5 cm, 52.6 kg for female students. The 52.5% of high school students were normal weight and 41.5% of them were underweight. Female students(46.7%) showed higher proportion of underweight than male students(37.0%). The students(50.9%) ate breakfast irregularly and most students(92.5%) ate Korean food for breakfast. The dietary changes of high school students over past few years showed that the intake of vegetable, fruit and yogurt were increased. The food habit score showed no significant difference by gender, mother's employment and monthly spending money. The nutritional knowledge score of female students were higher than the score of male students. Most high school students(93.9%) were highly stressed in their living. The stress score(3.35) of female students were higher than those of male students(3.15). However, excercise, eating slowly and good appetite could lower their perceived stress.

This study was to examine perceptions of information technology(IT) competencies among gifted and non-gifted students(i.e., information science high school students and technical high school students). Of the 370 high school students surveyed from 3 high schools(i.e., gifted academy, information science high school, and technical high school) in three metropolitan cities, Korea, 351 students completed and returned the questionnaires yielding a total response rate of 94.86%. High school students recognized the IT professional competence as being most important when recruiting IT employees. And they considered that practice-oriented education was the most importantly needed to improve their IT skills. In addition, the most important sub-factors of IT core competencies among gifted academy students and information science high school students were basic software skills. Also Technical high school students responded that the main network and security capabilities were the most importantly needed to do so. Finally, the most appropriate training courses for enhancing IT competencies were recognized differently among gifted and non-gifted students. Gifted academy students responded that the 'algorithm' was the mostly needed for enhancing IT competencies, whereas information science high school students responded that 'data structures' and 'computer architecture' were mostly needed to do. For technical high school students, they responded that a 'programming language' course was the most needed to do so. Results are discussed in relations to IT corporate and school settings.

This research was executed in order to analyze the factors and strengths of learning difficulties that science-gifted high-school students experienced in Korea Science Academy. The subjects are 284 gifted high-school students from Korea Science Academy who responded to a paper-and-pencil questionnaire survey. The questionnaire used in this research was developed by focusing on the difficulties in the learning situations of science-gifted highschool students based on Rhodes' 4P theory of creative achievement. The data was analyzed using cross-tabulation analysis, frequency analysis, MANOVA by the SPSS 12.0 program. The analysis of the questionnaire survey on the learning difficulties showed (i) a grade difference in interpersonal relationship and (ii) gender differences in learning ability and learning strategies. Also, it was observed that the students tried to solve their learning difficulties most frequently by meeting their school peers except for methods of 'the others' such as relying on religious power.

Special educations for gifted students have not been given enough attention in Japan with a little exception. Indeed, such educations were sometimes despised in Japan by teachers and parents as well as by boards of education, because one of the features of postwar education system in Japan was an excessive egalitarianism. The other is cramming of knowledge in school education, which is necessary for high school graduates to pass entrance examinations for famous universities such as University of Tokyo, or Kyoko University. However, in 1997, some trials of special educations for gifted students started. The Ministry of Education, Sports, Culture, Science and Technology admitted 'skipping a year to enter universities.' In this paper, the following three topics would be discussed. 1. Enrollment of high school students aged 17 into Chiba University. 2. Summer seminars conducted by Japan Mathematics Foundation of Olympiad. 3. Super Science High School Program funded by the Ministry of Education.

This study examines the various types of consciousness about sexuality exhibited by girls' high school students. The analysis was carried out utilizing two subject groups with the first being academic course students and the second being vocational course students. A 51 question questionnaire was prepared based on a literature review and previous research. The questionnaire was developed based on the results of two preliminary surveys, a reliability test, and a correction. A total of 721 questionnaires were distributed to students of 3 vocational and 3 academic courses. The analysis of the results was carried out using by means of SPSS 10.0. The study generated conclusive findings about each groups' viewpoint toward sex, the actual condition of their relationship with members of the opposite sex, the passages of knowledge about sex, the content of current sexuality education at school and the ideal type of sexuality education. This study shows that the current standardized content of sexuality education is ineffective. Sexuality education at schools in South Korea has reached a point, where research for more effective sexuality education is required.

The purpose of this study was to investigate the cognition of high school students and science teachers on the endocrine disruptors. Subjects of this study were 204 high school students and 26 science teachers. The results were as follows. Students obtained informations about endocrine disruptors mainly through mass media like TV, radio or lesson in school. Most of them were interested in endocrine disruptors and they thought that endocrine disruptors were very dangerous for people. And they preferred learning materials such as movies, images, and animations, but they didn't want to participate in activity of education on endocrine disruptors actively. Science teachers has agreed to needs of education on endocrine disruptors and has required education programs such as movies, images or animations for effective endocrine disruptors education.

Comparative studies on mathematical modeling cognition feature were carried out between 15 excellent high school third-grade science students (excellent students for short) and 15 normal ones (normal students for short) in China by utilizing protocol analysis and expert-novice comparison methods and our conclusions have been drawn as below. 1. In the style, span and method of mathematical modeling problem representation, both excellent and normal students adopted symbolic and methodological representation style. However, excellent students use mechanical representation style more often. Excellent students tend to utilize multiple-representation while normal students tend to utilize simplicity representation. Excellent students incline to make use of circular representation while normal students incline to make use of one-way representation. 2. In mathematical modeling strategy use, excellent students tend to tend to use equilibrium assumption strategy while normal students tend to use accurate assumption strategy. Excellent students tend to use sample analog construction strategy while normal students tend to use real-time generation construction strategy. Excellent students tend to use immediate self-monitoring strategy while normal students tend to use review-monitoring strategy. Excellent students tend to use theoretical deduction and intuitive judgment testing strategy while normal students tend to use data testing strategy. Excellent students tend to use assumption adjustment and modeling adjustment strategy while normal students tend to use model solving adjustment strategy. 3. In the thinking, result and efficiency of mathematical modeling, excellent students give brief oral presentations of mathematical modeling, express themselves more logically, analyze problems deeply and thoroughly, have multiple, quick and flexible thinking and the utilization of mathematical modeling method is shown by inspiring inquiry, more correct results and high thinking efficiency while normal students give complicated protocol material, express themselves illogically, analyze problems superficially and obscurely, have simple, slow and rigid thinking and the utilization of mathematical modeling method is shown by blind inquiry, more fixed and inaccurate thinking and low thinking efficiency.
