The purpose of this study is to analyze characteristics of problem solving in mathematics for gifted students through case study on solving the mathematical problem for gifted students, and to investigate what are relationships with the cognitive and affective characteristics. To this end, this study was to analyze the characteristics on the problem solving in mathematics by using qualitative research method after it selected two students who had specific education for brilliant students. As a result, this study has shown that it had high preference for question with clear answer, high preference for individual inquiry learning, high adhesion to answer for question, and high adhesion for assignment on characteristics of process of problem solving, but there was much difference in spirit of competition. As to the characteristics of thoughts in problem solving, this study has shown that it had high grasp capacity, intuitive insight, and capacity for visualization, but there were differences in capacity for generalization and adaptability. However, both two students had low values in deductive thought. In addition, as to the home environment and cognitive and affective characteristics, they were not related to the characteristics on problem solving directly, but it has shown that it affected each other indirectly. As to the conclusion of this study, this researcher thinks that it will be valuable documentation in order to improve curriculum, development of textbooks, and teaching method for special education for the gifted students and education for secondary mathematics.

In the TIMSS assessment goal and open TIMSS 2007, Singapore recorded a lower overall achievement level compared with Korea; however, the excellent results shown by Singapore furnished an opportunity for various countries to research into the education in Singapore. This paper conducted a comparative analysis of the "Proportion, Proportional Expression, and Percentile" area out of the three topics involving "Fractions and Decimals", "Proportion, Proportional expression, and Percentile", and "Measurement", in all of which Singapore exhibited a higher percentage of correct answers than Korea. The paper was able to discover the following differences through a comparative analysis of how Korean and Singaporean textbooks deal with the open questions of TIMSS 2007 after looking into them according to four assessment goals. First, the Singaporean textbook introduced the concept of proportion one year ahead of the Korean textbook. Second, the Singaporean textbook repeatedly coped with the topic of "Proportion, Proportional Expression, and Percentile" in depth and by academic year, and its volume was larger than that of the Korean textbook. Third, there was a difference in the introduction and definition of the concept of proportion. Fourth, the way of introducing a proportional expression was also different, and the Singaporean textbook proposed many more questions that utilize this expression in ordinary life. Based on these differences, the paper suggested implications that could be applied to the Korean curriculum and textbook.

In this paper, the life of Emmy Noether is reviewed in context of today's society where progress in social and educational equality for women have not significantly impacted the participation of women mathematician at the highest level of mathematics study. Recent studies have shown that there is little or no gender difference in mathematics performance if the women are treated equally in the country. Yet, the number of women scientists/mathematicians at the university level or related research centers are very low for all countries including the U.S. as well as Korea. Emmy Noether became a mathematician in early 20th century Germany where women were discouraged(not allowed) from even studying mathematics at the University. She overcame gender, racial, and social prejudices of the time to become one of the greatest mathematicians of the 20th century as a founding contributor of Abstract Algebra. Overcoming all the difficulties to focus on the study of mathematics to contribute at the highest level of mathematics provides an example of leadership for both men and women that is relevant today. Especially for women, Emmy Noether's life is a study in perseverance for the love of mathematics that proves that there is no gender difference even at the highest level of mathematics.

Educating gifted students in invention is a totally new area for researchers as well as educators. Establishing the theoretical concept of the gifted in invention has been a challenging task to many education researchers in Korea for last several years. This study was conducted to understand characteristics of the gifted in invention with the eventual purpose to conceptualize 'giftedness in invention.' The Future Mind by Gardner was adopted as the frame for categorizing the characteristics of the gifted in invention. Based on Five Minds, this study listed 25 factors with their 80 characteristics after intensive literature review and field surveys. The findings of this study are expected to contribute to establishing the theoretical base of educating the gifted in invention, to identifying gifted youngsters to be great inventors, and to designing the educational programs for them.

This study is to understand gifted students' suicidal ideation and its related variables among gifted students. For this, this study explores the relationship between maladaptive perfectionism of gifted students and suicidal ideation, confirming mediating effects of depression and academic stress. For the study 320 middle school students who were identified as the gifted at a gifted education center affiliated with the university. The results are summarized as follows. First, the fit of measurement model was found to be ${\chi}^2$=228.571(df=110, p=.000), CFI=.972, TLI=.966, RMSEA=.058, indicating most of fit indexes were acceptable. Second, suicidal ideation was found a significant positive relationship with maladaptive perfectionism, depression, academic stress. Third, as a result of examining path coefficient, it was found to be influenced significantly by all of the path from maladaptive perfectionism to depression and academic stress, the path from depression to suicidal ideation, the path from academic stress to suicidal ideation. However, the path from maladaptive perfectionism to suicidal ideation was found to be statistically insignificant. Fourth, the result showed that depression and academic stress worked as complete mediators between maladaptive perfectionism and suicidal ideation. These findings give useful information about affective aspects of gifted adolescents in hard circumstances. The results of the study will be helpful in devising consultation and educational programs for the gifted who are in danger of suicide.

In this study, using a questionnaire about camp programs, we surveyed 375 gifted education institutes, including 285 classes for the gifted, 70 institutes for the gifted at education offices, and 20 institutes for the gifted at universities. The survey questionnaire consists of questions relating to camp design, camp operation, and camp introspection. The questions relating to camp operation are subdivided into questions relating to content, process, product, and learning environment of the camp. In the analysis of camp design, experience-centered camps entailing visits to research institutes, science museums, and so on showed the highest ratio. The camps were generally carried out in summer vacation as two day/one night programs. The average score of camp content was 3.72, that of camp process was 3.78, that of camp product was 3.77, and that of camp environment was 3.58. In the analysis of camp introspection, the item 'a lack of information about diverse camp activities' showed the highest difficult thing. Integrating these results, we suggest that information about diverse camp activities should be developed and supplied and the camp environment strengthen the freedom of students to select camp activities.

The research attempts to explore legal issues related to teacher certification in gifted education. For this end, first, the institutional processes of the 'Law of the Promotion of Education for the Gifted and Talented' and its legal characteristics were reviewed. The 'Law of the Promotion of Education for the Gifted and Talented' appeared to be superior to the 'Law of Elementary and Secondary School Education' in order to ensure the right of the gifted to receive a proper education. In consequences, regulations related to teacher certification in gifted education should require to obtain professional knowledge and ability in addition to general education teacher certification. Second, the differences between 'Law of the Promotion of Education for the Gifted and Talented' and 'Law of Elementary and Secondary School Education' were analyzed. It was found that the 'Law of the Promotion of Education for the Gifted and Talented' is not sufficiently articulated in terms of required and elective courses and hours to certify teachers for the gifted as well as their employment at gifted educational institutions. In conclusions, further attentions to legal imperatives in gifted education are called for establishing and upgrading teacher certification in gifted education.

As a way of improving social receptivity of using radiation, this study looked into the difference of understanding the need of using radiation in various fields between students majoring in radiation and non-radiation related studies, who will influence public opinion in the long term. This study also provides data needed for developing efficient strategies for projects promoting the public's awareness of using radiation. Of the students in the 79 schools sampled, 24%(177) were in 4 year colleges and 146 were junior colleges in educational statistics service (http://cesi.kedi.re.kr) In November 2010 1,945 students were selected as a sample, and they were given surveys on the need of using radiation in different fields. As a result, both between students majoring in radiation and non-radiation related studies showed a high level of understanding the need for radiation in the medical field and showed a low level of understanding of the need for radiation in the agricultural field. In all 6 fields of radiation use, students majoring in radiation related studies showed higher levels of understanding for the need to use radiation than students majoring in radiation and non-radiation related studies. In each field, male students and those who have experience medical radiation and relevant education had higher level of understanding. This shows we need to improve the understanding of the cases of female students and those who have not had experiences with medical radiation and to provide relevant education through various kinds of information. The characteristics of the groups that are shown in the results of this study are considered to be helpful for efficiently for project promoting the public's awareness of using radiation.
