This study examined the reasoning of gifted elementary science students in a socioscientific issues (SSI) classroom discussion on COVID-19-related trash disposal challenges. This study aimed to understand the characteristics of evidence use and decision-making difficulties in each type of SSI-related reasoning. To this end, the transcripts of 17 gifted students of elementary science discussing SSIs in a classroom were analyzed within the framework of informal reasoning. The analysis framework was categorized into three types according to the primary influence involved in reasoning: rational, emotional, and intuitive. The analysis showed that students exhibited four categories of evidence use in SSI reasoning. First, in the rational reasoning category, students deemed and recorded scientific knowledge, numbers, and statistics as objective evidence. However, students who experienced difficulty in investigating such scientific data were less likely to have factored them in subsequent decisions. Second, in the emotional reasoning category, students' solutions varied considerably depending on the perspective they empathized with and reasoned from. Differences in their views led to conflicting perspectives on SSIs and consequent disagreement. Third, in the intuitive reasoning category, students disagreed with the opinions of their peers but did not explain their positions precisely. Intuitive reasoning also created challenges as students avoided problem-solving in the discussion and did not critically examine their opinions. Fourth, a mixed category of reasoning emerged: intuition combined with rationality or emotion. When combined with emotion, intuitive reasoning was characterized by deep empathy arising from personal experience, and when combined with rationality, the result was only an impulsive reaction. These findings indicate that research on student understanding and faculty knowledge of SSIs discussed in classrooms should consider the difficulties in informal reasoning and decision-making.

The purpose of this study was to provide and analyze the fundamental data on leadership skills and to analyze leadership skills among giftd elementary students according to grade, subject and gender. The main research questions in order to achieve the purpose of research are as follow. First, are there any differences of gifted elementary students' leadership skills in gifted groups? Second, do leadership program have an effect on improvement of gifted elementary students' leadership skills? The subjects for this study were 488 gifted elementary in 4th-6th grade in Busan. The students in the experiential group went thought 16 session do leadership program. After that, they had pre-tests and post-tests. the devices used to verify the effectiveness of the program were leadership skill scales. For this research analysis, MANOVA was used to investigate the first research questions and MANCOVA was used to investigate the second research question. Results from this study are as follows. Firstly, students in higher grades received fewer leadership skills points. This fact suggests that the leadership programs from the fourth grade should be implemented in 5th and 6th grade gifted education as well. Secondly, in the analysis of the results from gifted mathematics and gifted science, little significant statistical difference was shown. Thirdly, the analysis of leadership skills according to gender showed statistical significance. Finally, the study showed that the leadership education program had a positive effect.

The purpose of this study was to analyze the scientific reasoning ability during open-inquiry activities of science-gifted 2nd middle school students. Open-inquiry activity is similar to process of scientists' science knowledge generation. Identifying and analyzing the scientific reasoning process and the scientific reasoning ability during open-inquiry activities of science-gifted students, will be able to provide implications for future research. CSRI Matrix(Dolan & Grady, 2010) was used to analyze the complexity of the scientific reasoning ability. The higher degree of complexity of the scientific reasoning is similar to process of scientists' science knowledge generation. The results showed that each process of the open-inquiry activities were distributed by various steps of complexity of the scientific reasoning. Particularly, 'The generating questions' and 'Connecting data to the research question' were 'most complex' step in all teams. On the other side, 'Posing preliminary hypotheses', 'Selecting dependent and independent variables', 'Considering the limitations or flaws of their experiments' were low steps in most teams. And 'Communicating and defending findings' was distributed by most various steps of complexity of the scientific reasoning.

과학교육은 학생들이 장차 과학 기술분야의 직업을 추구하도록 하는 것을 그 중요한 결실의 하나로 잡고 있다. 현재 한국은 과학과 기술의 발전을 교육의 주요목표의 하나로 삼고 있으며, 정부에서는 보다 많은 영재를 과학 기술분야로 유치하려고 여러 가지 정책을 펴고 있다. 그러나 이러한 정책도 결국은 학생이 과학 기술분야로 모여들지 않으면 그 효과가 없게 된다. 그런 점에서 학생들이 어떤 이유로 과학 기술분야를 선택하는지 혹은 기피하는지 그 원인을 아는 것을 중요한 과제라고 할 수 있다. 본 연구는 과학 및 기술분야의 직업을 갖게 되는데 결정적인 역할을 하는 고교생의 문 이과반 선택에 있어 그 진로결정에 영향을 주는 제 요인들을 규명하는데 목적을 두고있다. 연구대상은 대구시내외 남 녀 고교 1학년생 109명(문과 56명, 이과 53명)이었으며 조사방법은 설문지법을 사용하였다. 조사결과는 학생들의 문 이과반 선택에는 장래직업, 대학전공, 적성, 학과목에 대한 능력, 흥미 선호도, 가족 및 주위의 권유 등이 주요요인임을 보여주고 있다. 그중 문과를 지원한 학생들은 대체적으로 자신의 적성 이과과목에 대한 능력부족 인식, 내신 및 학력고사에서의 성적취득용이성 등 주로 자신의 내적 동기와 관련된 요인들을 들고 있는데 비해, 이과를 지원한 학생들은 밝은 직업전망, 가족 및 주위의 권유 등 외적인 동기도 큰 작용을 하고 있음을 보여 대조를 이루고 있다. 또 문과를 지원한 학생은 이과가 공부하기가 어렵고 성적을 올리기도 힘들어 이과를 기피한 경향을 보이는데 반해 이과 지원자는 문과를 기피하여 이과로 왔다는 응답은 별로 없는 점이 대조를 보였다. 본 논문은 이러한 결과가 던져주는 시사점과 과학교육의 개선책에 관한 제언을 제시하면서 결론을 맺고 있다.

The purpose of this study is to investigate various types of 'flow' that can be observed in the daily lives of science-gifted students, and the correlation between 'flow' and creativity. For two months, we have gathered data on 'flow' in the main activities of science-gifted students through a qualitative application of the Experience Sampling Method (ESM). We then use correlation analysis to determine whether there have been correlations between 'flow' and creativity. Among the four channels, activities involving 'flow' have been the most common (40.4%) in the daily lives of the students. The types of tasks done by the students are, in descending order of frequency, productive activities, social activities, leisure activities, and basic activities. The students have shown the least interest in tasks that do not require specific skills or pose significant challenges; thus the least interest show in basic activities and the most interest has been shown in productive activities. 'Flow' and creativity are significantly correlated at the level of 0.01, which means that the more the students experience 'flow,' the more they express creativity. Based on the results above, we have found that there is a need for the development of science programs or environments, including productivity while at the same time, to reduce uneasiness and patience raising activities, where students can experience more 'flow' in daily life.

The purpose of this study is to provide some necessary baseline data to the information prodigy related research through the study on the brain left/right tendency of information prodigies. Subjects were 298 gifted students(59 information, 79 mathematics, 80 science, 40 invention, 40 social science) and 114 general students summing up 412 in the schools of Daejeon metropolitan area. 'Brain Tendency Test' developed by Torrance and modified by Ko in Korean was used as a tool to measure the prodigies' brain tendencies. Data analysis has been done with the $x^2$ test of frequency with the alpha = .05. The results of this study are as follows. 1) The information gifted students have tendencies of utilizing right brain hemisphere at the most, both left/right brain(whole brain) utilization at the second, and left brain utilization at the last. 2) There was statistically no difference between information prodigies and general students in the left/right brain tendency. 3) There was statistically mild evidence to support the notion that there are some differences in the brain tendency between the group of information prodigies and the group of other area of the prodigies. The degree of inclination to utilize the whole brain hemisphere for the prodigies of the other area was the highest compare to other left/right brain utilization while the information prodigies tend to utilize the right brain hemisphere at the most. 4) The female information prodigies have tendencies of utilizing while brain area at the most, right brain utilization at the second, and left brain utilization at the last contrary to the brain utilization tendencies in the male information prodigies which are the same as the brain utilization tendencies of the information prodigies. However there was no difference in brain tendencies statistically between the two groups since the female subjects were too small.

The purposes of this study are 1) to revalidate the developed Measuring Instrument Systems Thinking and 2) to compare systems thinking skills between gifted and non-gifted high school students. For the test, 116 gifted science students and 553 non-gifted students were sampled from high schools. Exploratory factor analysis and confirmatory factor analysis were performed and Independent t-test was performed using the average of the two groups. The finding of the exploratory factor analysis indicated 5 factors in the model with 4 items per single factor. The result of confirmatory factor analysis was generally appropriate and acceptable (5 factor model: ${\chi}^2/df$ : 2.765, TLI=.907, CFI=.929, IFI=.930, RMSEA=.044). The reliability for 20 items turned out to be high because the Cronbach's alphas were at .875 and .693~.751 per each factor. In addition, the result of t-test showed that systems thinking skills among gifted science students were significantly higher than non-gifted students. This study could be expanded to measuring systems thinking with qualitative research tools and to various school levels.
