The purpose of this study is to develop the syringe experiment device which is able to analyze the relationship between the length of the air pillar and resonance frequencies quantitatively for the education of sound resonance. We made an air pillar resonance device with a 'Head', which is used by the disposable syringe and the plastic sphere for constructing molecular models. We also assembled PC experiment equipment which is used by commercial software. As a result, it appears this equipment can be used instead of the current device used by experts. It was proved that this syringe device is not the 'pipe' but the 'Helmholtz resonator'. It appears that data through resonance experiments can prove the sound resonance phenomenon. In conclusion, this syringe resonator is the experiment device that can be used in the gifted education for middle-high school students and acoustic experiments for university students.

The purpose of this study was to analyze perfectism, interpersonal characteristic between the gifted & talented students and the general. The subject of this study were 112 the gifted students and 120 the general. They answered the questions about perfectism and interpersonal characteristic. To compare the gifted and general students' tendency, collected data was classified by their gender and grade. And correlation analysis was done in oder to analyze the relation between the gifted students' perfectism and interpersonal characteristic. The important results of this study were as follows. First, the grade gap of perfectism was not meaningful in both groups. Otherwise, the gender gap of perfectism was meaningful in both groups. Female's perfectism was higher than male's. And the gifted students' perfectism was higher than the general students'. Second, Differently, the gender gap of interpersonal characteristic was meaningful in the same group. Female had higher positive social-relationship, expression tendency than male. But female had lower competition-aggressiveness propensity than male. In the general group, the 6th grade students showed more positive role, social-relationship than 5th grade. And male showed more competition-aggressiveness propensity than female. Comparing the gifted and the general, the gifted had more dominant-superior, exhibitionistic-narcissistic propensity. It could be a reason of the gifted students' social problem. Third, among self-oriented perfectism and dominant-superior, independent-responsible propensity had meaningful correlation. Also socially-prescribed perfectism had influenced on dominant-superior, sociability-friendliness, exhibitionistic-narcissistic propensity.

This study aims to analyze the relationship between scientific content knowledge of science-gifted elementary students and their expression of scientific creativity, and the characteristics of divided groups according to the levels of their scientific content knowledge and scientific creativity. A science-gifted program was implemented to 33 forth-graders in the Science-Gifted Education Center of an education office in Seoul, Korea. The method of evaluating scientific knowledge was divided into well-structured paper-pencil test (asking specific and limited range of content knowledge of plants) and ill-structured descriptive test (stating all the knowledge they know about plants) to find out which methods were more related to scientific creativity. In addition, in order to find out the characteristics of each group according to the level of scientific content knowledge and scientific creativity, students were required to answer a questionnaire about their own self-perception of scientific knowledge and scientific creativity and how to obtain scientific knowledge. The main results of this study are as follows. First, Both well-structured paper-pencil test (r=.38) and ill-structured descriptive test (r=.51) results of elementary science gifted students were significantly correlated with scientific creativity. Second, As a result of the regression analysis on scientific creativity of science-gifted elementary students, both the knowledge measured by the two evaluation methods have the ability to explain scientific creativity. Third, the students were categorized into four groups according to the levels of their scientific content knowledge and their expression of scientific creativity, and the result showed that the higher the knowledge of science, the higher the scientific creativity. Fourth, the description about self-perception of scientific knowledge revealed that the highest percentage of Type LL students of all 13 students (53.8%, 7 students) answered 'I have little knowledge of plants because I have little interest in them.' Fifth, the description about self-perception of scientific knowledge revealed that the highest percentage of Type HH students of all 15 students (40%, 6 students) answered 'I think my science creativity is high through my experience of scientific creativity. Sixth, the responses to the Questionnaire revealed that 'reading' was the most popular way to obtain scientific knowledge, with 27 out of total 33 students choosing it. In particular, all 18 students from Type HH (high scientific knowledge and high scientific creativity) and Type HL (high scientific knowledge and low scientific creativity) - those with high scientific knowledge - gave that response. On the basis of this research, we should explore practical teaching methods and environment for gifted students to improve their scientific creativity by revealing the nature of the factors that affect scientific creativity and analyzing relationship between knowledge and scientific creativity.

This study analyzed the relationship between self-directedness of science-gifted elementary students and their expression of scientific creativity in science-gifted class. A science-gifted program on the topic of Hydraulic Machine was implemented to 34 fifth-graders in the Science-Gifted Education Center of an education office in Seoul, Korea for four weeks. The self-directedness of the gifted students was divided into three types of 'General, Scientific, and Topic-Related Self-Directedness'. The products of the students' activities were assessed by using a scientific creativity assessment formula. Qualitative research, such as analysis of observations and interviews, was also conducted in order to identify characteristics that were not apparently revealed by quantitative data. The main results of this study are as follows: First, science-gifted elementary students' general self-directedness and their scientific creativity were significantly correlated (r=.373). Second, the students' scientific self-directedness and scientific creativity did not have a significant correlation (r=.294). Third, there was a positive correlation between the students' topic-related self-directedness and their expression of scientific creativity. Their self-rated scores (r=.420) for the topic-related self-directedness and the number of activity types associated with the topic had a positive correlation (r=.350). Fourth, the students were categorized into four groups according to the levels of their self-directedness and scientific creativity, and the result showed that Type HH (high self-directedness and high scientific creativity) was the most common type (15 students, 38.5%), followed by Type LL (low self-directedness and low scientific creativity) (11 students, 28.2%). Eight (20.5%) and five students (12.8 %) belonged to Type LH (low self-directedness and high scientific creativity) and Type HL (high self-directedness and low scientific creativity) respectively. Fifth, the classroom observation of the students in groups revealed that groups with more number of Type HH demonstrated better cooperation and performance. Sixth, the analysis results of the observation were almost matched to the results of the self-directedness and scientific creativity tests. The students with higher self-directedness demonstrated active class participation and good cooperative skills. The students with higher scientific creativity had a tendency to generate creative ideas more frequently in given situations. Seventh, dynamic activities were perceived as enjoyable and exciting by 76.9% of the students, but static activities that require creativity were regarded as interesting only by 23.1% of the students. Among the students who were satisfied with both the creative and static activities, Type HH accounted for the largest proportion (55.6%). In conclusion, factors such as students' interests, initiatives, and attitudes displayed through voluntary participations originated from their own daily life can predict the degree of scientific creativity associated with the topic. Also, when students were categorized into four types according to the level of self-directedness and scientific creativity, there was a tendency of active behavior in class, cooperative skill, and activity satisfaction. This suggested that we should consider self-directedness and scientific creativity in selecting the gifted, grouping them in class, and designing and executing programs for science-gifted elementary students.

The purpose of this study was to investigate the relation between the learning styles and science process skills of students of the gifted class in elementary school. Subjects were forty-eight students of the gifted class who are in the fifth grade studying at the gifted class of S elementary school in Bucheon, M and Y elementary school in Incheon on learning styles and science process skills of students. Learning Style Profile (LSP) was used as instrument to survey learning style of students of the gifted class which was developed by NASSP, and consists of four categories (cognitive skills, perceptual response, orientation and teaming preferences) and twenty-four subscales. The results of this study were as follows: 1. In the learning styles test, students of the gifted class have higher scores of spatial skill, sequential processing skill, persistence orientation, manipulative preference, temperature preference and afternoon preference than general class students, but they have lower scores of discrimination skill and lighting preference, and there were statistically significant difference. 2. In science process skills test, there were statistically significant difference between students of the gifted class and general students. 3. In the correlation between the learning styles and science process skills, there was positive correlation of observing skill with spatial skill and manipulate skill of cognitive skill domain. For classifying skill, there was positive correlation with visual perceptual response, but was negative correlations with auditory and emotive perceptual response of perceptual response domain and with evening preference and verbal risk orientation of study preference domain. For measuring skill, there was positive correlation with sequential processing skill of cognitive skill domain. For formulating hypotheses, there was controlling variables, there was positive correlation with sequential processing skill and simultaneous processing skill of cognitive skill domain, and with verbal-spatial preference and early morning study preference of study preference domain. When planning and managing the gifted class, it will be beneficial and effective to consider the meaningful relations between the elements of loaming style and science process skills in order to improve science process skills.

This study aims to compare student self-, teacher-, and objective assessments of elementary science-gifted students' scientific creativity. A science-gifted program on the topic of Hydraulic Machine was implemented to 40 fifth-graders in the Science-Gifted Education Center of an education office in Seoul, Korea for four weeks. The products of the students' activities were assessed by three types of 'Student Self-Assesment', 'Teacher-Assesment', and 'Objective Assessment using Formula'. Based on two essential components of creativity, the scientific creativity is divided into two parts of originality and usefulness. Ideas that satisfy both components can be counted as scientifically creative. The main results of this study are as follows: First, the scores of each week and the average of the overall four-week scores on scientific creativity were significantly correlated. Student self-assessment (r=.687), teacher-assessment (r=.715), and objective assessment (r=.724) appeared consistently over instructional periods. Second, the average scores of student self-, objective, and teacher-assessments were 73.15, 35.72, and 26.60, respectively. The result of student self-assessment on scientific creativity tended to be higher than those of formula and teacher. Third, among the three types of assessment on scientific creativity, a strong correlation appeared between teacher- and objective assessment (r=.974), but neither between student self- and objective (r=.161) nor between student self- and teacher- (r=.213). Fourth, the scores on originality component had a positive correlation between teacher- and objective assessment (r=.713). The scores of student self- and teacher-assessments had a significant correlation too (r=.315), but not between student self- and objective assessment (r=.279). Fifth, the scores on usefulness component did not have a significant correlation between student self- and teacher-assessment (r=.155). Sixth, there was no significant difference on scientific creativity between student self- and objective assessment [${\chi}^2$(1, n=40)=1.667, p<.197]. Not between student self- and teacher-assessment either [${\chi}^2$(1, n=40)=1.616, p<.204]. On the contrary, there was a significant difference between teacher- and objective assessment [${\chi}^2$(1, n=40)=32.593, p<.000]. Seventh, the students were categorized into four groups according to the levels of their scores by student self- and teacher-assessment. The result showed that factors influencing student self-assessment are inherent in the personality traits of gifted individuals, such as self-esteem and perfectionism. The findings suggested that there are challenges for the educators to make efforts to construct consistent assessment methods for scientific creativity.

How would environmental education be implemented for effectiveness today? Deep reflection on the way of teaching environment in classes to achieve effectiveness is required. If there exist differences in students' environmental perception depending on environment class pattern, its most effective way should be looked for. In environmental education, inducing the students to have advisable attitude voluntary about environment is more important than teaching them environmental knowledge. From such view, students' active participation is necessary for successful environmental classes. Students need to be set to share their principle, values, attitude about environment problems at environmental class through presentation which is important factor to make them have advisable environmental attitude. Therefore, environmental class need to be carried out student-led way. For that, a class model need to be designed which will be helpful for the students to arrange and elaborate their emitting thought about environment problems through disclosing their thoughts to share them with fellow students which will end up in their advisable environmental attitude. This study aimed to find out the effectiveness of environmental collage making class contributive to offering various environmental perception to students and grasping others' thinking about environment. Fifty-eight 10th graders at U Science High School in Ulsan metropolitan city were selected for the study that carried out from 2010 April to June by choosing total 10 environmental themes divided into environmental collage making class applied to the 30 test group students, and general environmental class applied to 28 control group students. Following are the study results. First, in students' environmental sensitivity, the students in the environmental collage making class appeared to be higher compared with them in general environmental class. Second, in students' intentional environment action, the students in the environmental collage making class appeared to be higher compared with them in general environmental class. Third, in students' satisfaction with environmental class, the students in the environmental collage making class appeared to be higher compared with them in general environmental class.

Math classes has been regarded as an independent area of a teacher and his/her students of a particular class. In Recent discussions about the professional development of teachers, for the improvement of practices, the point of view of that the community of teachers must work together is spreading. What are the considerations in organization and operation of learning communities for professional development of teachers? In this study, we analyzed the case of the learning community of math teachers in a Science Academy for the purpose of improving math classes to promote the participation of learners. Research results show that teachers share the principles and goals of mathematics teaching through the learning community. Also, through participation in learning communities, the members were practicing the lessons improved by reflection on the lessons of his/her and their colleagues. These results provide implication that it is important to provide opportunities for objectifying his/her classes through the learning community for a substantial improvement in math classes.

Today, the importance of environmental education is a matter we are all concerned about. The environment surrounding us, such as the air we breathe, the water we drink, and the soil plants grow in, is critical for our survival. Currently there is a lot of interest in environmental education at the elementary, middle, and high school levels. This is a result of the deep recognition of the importance of the environment. However the environmental education being conducted in schools is not yet at a satisfactory level. The practical issues, including an entrance exam-oriented atmosphere, student' and parents' lack of understanding, and teachers' lack of expertise in environmental education, interfere with the stability of environmental curriculum in the schools. Accordingly, we need to devise an alternative environmental curriculum due to the fact that it hasn't been included as a regular subject in the curriculum of many national schools. This study, carried out from April to December 2009, was an examination of the effect of volunteer work at the place of ecology experience on the environmental sensitivity & state-trait anxiety of the 61 Gifted Students. The students were divided into two groups. The test group consisted of 30 gifted students who did volunteer work at the place of ecology experience run by Ulsan Science High School, in Ulsan Metropolitan City. The control group consisted of the rest of the students. The following are the study results: First, the volunteer work at the place of ecology experience was influential in increasing the environmental sensitivity of the gifted students. Second, the volunteer work at the place of ecology experience was influential in decreasing the state anxiety of in gifted students. Third, the volunteer work at the place of ecology experience was influential in decreasing the trait anxiety of in gifted students. Fourth, the volunteer work at the place of ecology experience positively influenced not only the gifted students' view of environmental education, but also their overall character.
