The purpose of this study was to develope a high school level physics curriculum for the gifted in science. The research method for this study was Delphi Survey, which is appropriate for social agreement of experts in a certain area. For the Delphi survey, 11 experts of gifted education in physics field, who consist of 4 physics professors, 3 physics education professors, and 2 science high school teachers, and 2 experts in other institutes, were sampled intendedly. In first survey, free description questions about objectives, contents, teaching methods, and achievement test methods were asked, and their answers were analyzed by frequency. And then, frequent answers were adopted and elaborated. In second survey, they were asked to write numbers according to priority(degree of agreement) for the adopted and elaborated answers in each area. Finally, by analyzing the results of second survey, the physics curriculum for the gifted was developed.

This paper is focused on the development of sea wave experimental module for the science gifted students and the potential of its application in high school earth science. Sea wave experimental module for the gifted was characteristics by five phases: Engagement, Exploration, Explanation, Elaboration, and Expansion. Subjects were 16 gifted students, who were 10th graders and have been taught in the adjacent Education Institute for the gifted of Education Districts, Daejeon Metropolitan Office of Education The changes of inquiry ability and knowledge achievement were analyzed according to analysis of experimental report and pre-test and post-test. Experimental module for the gifted was very effective on inquiry skills as follows: control of variables, experimental designing, and selecting tools of experimental process. And also it was positively effective on achievement. The result of this study suggested that experimental module for the science gifted should be very meaningfully to improve scientific ability of them, and the development and application of experimental module for the science gifted be needed for them.

Sonoluminescence (SL) is the light emitting phenomenon accompanied with ultrasonic cavitation in liquid. It attracts many interests because physics behind it remains uncertain and few applications have appeared. It has been known that the color of SL changes in solutions which include metallic ions. In the present work, colors of SL in alkali metallic and alkaline earth metallic ions were considered. RGB component was used to analyze the color of SL. By using RGB component, it was found that color of SL in metallic solution can be resolved into color of SL in pure water and flame color of metal which is different from high intensity color of line spectrum of alkaline earth metal. From this result, influence of metallic ion on SL and the temperature on violent collapsing of cavitation bubble was discussed.

This study is intended to reconsider the meaning of the education for gifted/talented children, the foundation object of science high school by examining the behavior characteristics between gifted students and talented students in open-end mathematical problem solving and to provide the basis for realization of 'meaningful teaming' tailored to the learner's level, the essential of school education. For the study, 8 students (4 gifted students and 4 talented students) were selected out of the 1 st grade students in science high school through the distinction procedure of 3 steps and the behavior characteristics between these two groups were analyzed according to the basis established through the literature survey. As the results of this study, the following were founded. (1) It must be recognized that the constituent members of science high school were not the same excellent group and divided into the two groups, gifted students who showed excellence in overall field of mathematical behavior characteristics and talented students who had excellence in learning ability of mathematics. (2) The behavior characteristics between gifted students and talented students, members of science high school is understood and a curriculum of science high school must include a lesson for improving the creativity as the educational institutions for gifted/talented students, unlike general high school. Based on these results, it is necessary to try to find a support plan that it reduces the case which gifted students are generalized with common talented students by the same curriculum and induces the meaningful loaming to learners, the essential of school education.

We have investigated the recognition for the gifted science education program of middle school students being educated at the local center for the gifted. We developed a questionnaire that includes items for contents of the program, learning environments, participation attitude, effects of the program and improvements, and consists of it5-point Likert items and related descriptive items. 161 students at the local centers for the gifted responded to the questionnaire. The total score was 3.70 on a 5-point Likert scale. The score of effects of the program was highest, learning environments was the lowest. Most of the students referred that the participation of the programs help their schoolwork because of schoolwork preparations & review, learning the process of the solving problem and principle. On the contrary, difficult contents and long lesson hours interrupted their schoolwork. Students recognized that the programs are mainly composed of students' self-activities and the role of teachers is subsidiary. The programs have a good effect on them to increase interest in science and creative thinking. It is necessary that the program be improved in lesson hours, contents of the program, school facilities, and full service.

In this paper, it conducted the following works to develop the selective test for the gifted of information science in elementary schools. First, it presented the discrete mathematical thinking as an essential competence of elementary information science gifted, through theoretical research with many expert's studies, in order to investigate the definition and characteristics of information science gifted. Second, it developed a test to measure the discrete mathematical thinking, according to the results of analysis of discrete mathematical elements, appeared in the 7th national mathematics curriculum, in order to extract the characteristics of selective test for elementary information science gifted. Third, regarding the verification of items in a newly developed test, it adjusted the difficulty and discrimination by conducting 2 sessions of preliminary test, and then finally confirmed that the standards of items in the test, by testifying sufficient level of validity after the application to a main experiment.

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.
