The purpose of this study is to use DARTs (Directed Activities Related to text) to foster inquiry problems while actively engaging accelerated gifted elementary students in the field of earth sciences. This study is continually evolving in the classroom on the proposition that accelerate the scientific thought whether inquiry problems show any change according to the extent of prior background knowledge through DARTs. Researchers appointed the accelerated gifted elementary students with 14 investigation problems and it was their duty to not only classify the inquiry problems, but to analyze using interviewing methods according to type classification framework. Many scientific terms were used concretely in the inquiry problems that were propose after DART. The students gave a direct effect to the inquiry problem to be proposed according to the level of the content that it is presented in the DARTs worksheet. As a result, the NP-IP type and the EC-IP, NC-IP inquiry problem type proposed above much as a whole in DARTs former and prior. Particularly, the EMC-IP type and etc. was variously proposed after the DARTs. And the students proposing the inquiry problem of above average proposed the inquiry problem of the EP-IP type much unlike the general average student after the DARTs. The EC-IP, NC-IP and NF-IP type were changed much after DARTs used. Particularly, the EC-IP and NC-IP type were changed much.

The purpose of this work is to investigate pre-service elementary teachers' belief in science gifted education. To do that, from September to November 2012, this research had been conducted with 42 students who were in the third year of P University of Education. The conclusions of this work are presented as follows: First, the pre-service elementary teachers considered exploration ability to be the most important talent for the gifted students in science, and chose task commitment as the next most important. They regarded intelligent ability and leadership ability as the relatively less important. Secondly, regarding the most important tool in choosing scientifically gifted students, the pre-service elementary teachers preferred creativity test. It was found that they considered the intelligence test and academic achievements, which require intelligent ability, to be the less important. Thirdly, regarding the special knowledge related to science gifted education, the pre-service elementary teachers considered pedagogical knowledge about the gifted to be the most important. Fourthly, regarding a class type for gifted students in science, the pre-service elementary teachers most preferred project learning. Project learning is a learning method in which students choose an interesting problem and solve the problem in cooperation with group members. It is the most widely used exploration class in gifted education. It is in the same context as the result that exploration ability is the most important factor to elementary gifted students in science. This work revealed that, with regard to a talent for the gifted in science, judgment of the gifted in science and science gifted education, the potential ability and affective ability of gifted students are considered to be more important than their intelligent ability. Therefore, it was analyzed that pre-service elementary teachers' belief in the gifted students in science is almost consistent with the recent trend of gifted education.

The concept of the center of gravity is presently being introduced in elementary school curriculums and is broadly applied to Mathematics, Physics, and the Engineering field in University education which are mostly theoretical classes much separated from actual life in the practical educational field. In 2013, ${\bigcirc}{\bigcirc}$ University of Science and Gifted Education, had developed the multidisciplinary approach program of verifying the center of gravity for gifted students, but this program was reconstructed and applied to ordinary students and the effectiveness was analyzed to lay the foundation and generalize this convergence education. Including experiments for verifying the center of gravity in an object with a hollow interior and the existence of a center of gravity outside an object, I proposed realizing the calculations by considering the weight of the lever, the Principle of the lever being a core factor when finding the center of gravity. We altered the existing 8 step program to a 4 step program for the told 65 students from elementary, Junior and High School students, letting them freely select the class lecture by themselves. The analysis attained from surveys, debates and interviews showed that by precise error analysis, students achieved a higher success experience, showing us the importance of the development of a new convergence program.

The physical computing education, as the emerging field, is a form of education that helps learners to develop the attitude of scientific inquiry by developing meaningful and creative output through the integration of hardware and software elements. Based on the literature, the authors of the study used science experience, school support and learning flow as the variables that predict the outcome variable which is the attitude of scientific inquiry. The authors collected data from 64 fourth and sixth graders who studied physical computing at an institution for the gifted and talented in Korea and then analyzed them using descriptive statistics, correlation, multiple regression and simple mediation analysis methods. As a result, science experience and learning flow significantly predicted the attitude of scientific inquiry. In addition, learning flow mediated the relationship between science experience and the attitude of scientific inquiry, and the relationship between school support and the attitude of scientific inquiry. Based on these results, the authors propose that to promote the attitude of scientific inquiry in physical computing education, strategies must be implemented for improving science experience, school support and learning flow in instructional design.

This study resulted from a study regarding creative STEAM System based upon an experiment with the center of gravity. The results of the study are constructed by a fusion of mathematics and physics, showing that they are the same as mathematical calculations. Also, students can find that center of gravity of an object is in equilibrium on a metal rod when the center of gravity exactly is placed on the rod. The fact that an experimental results are correspond to calculations can maximize the effectiveness of teaching. And also this study has the following effectiveness. First, the exact construction and calculations arouses good competition among students. Second, this experiment can give students a motivation for study and increase their thinking in classes because the theoretical background of center of gravity experiment is basically attributed to math and science classes in school. This study includes three different types of center-of-gravity experiments. One is a simple type of experiment in which center of gravity exists inside of an object. Another is a complicated one in which the center of gravity is also inside of an object. However, the third type is an experiment in where the center of gravity is outside of an object. Therefore, it gives students an opportunity to discuss how to confirm equilibrium on a metal rod when the object has its center of gravity outside. Having discussions in class will allow students to have a critical way of thinking. In addition, searching for a way to solve a problem will increase creativity of students as well. And the last type is finding the center of gravity of a big acrylic panel where multiple objects are on the panel. According to the survey and interview conducted by students who participated in this program, teaching based on creative STEAM system helps students to get a better understanding and more fast acquisition of knowledge. We can expect that a well-planned creative STEAM system through a continuous study will be both effective and efficient in educating critical and creative students.

The purpose of this study was to determine the discrete intelligences from multiple intelligence affecting the social adaptive behavior, help to understand their relation and draw educational implications to be used in supporting gifted students who have social and emotional difficulties by comparing and analyzing the relation between multiple intelligence and social adaptive behavior of gifted and general elementary students. The conclusions of this study are as follows. First, the levels of both multiple intelligence and social adaptive behavior were significantly higher in gifted elementary students compared to general ones on all sub-factores, indicating that the gifted elementary students are more adaptive in such constructs as self-efficacy, self-esteem, communicative skill, school life and interpersonal skill compared to general ones. Second, the association between multiple intelligence and social adaptive behavior was statistically significant both in gifted and general elementary students, indicating that the two constructs have close relation with each other. Third, for the gifted elementary students, the logical-mathematical and interpersonal intelligences had explanatory powers for self-efficacy, self-esteem, communicative skill, adaptation in school life, interpersonal skill while, for the general ones, intra- and inter-personal intelligences had explanatory powers for most domains of social adaptive behaviors, indicating that development of intelligences affecting the social adaptive behavior many have positive effects on social and emotional development of both gifted and general elementary students.

This study was carried out to analyze primary gifted education systems in Korea and China. The results of the research are as follows : (1) The objectives of the gifted children education of two countries are same. They intend to dig out hidden talent and giftedness of gifted children. They emphasize the development of creativity in the gifted children through the various special teaching methods. (2) Korea has been doing the gifted education limitedly focused on the 4th grade students in elementary school after regular school curriculum, but China has performed gifted education from primary school to university quite systematically. (3) Korea tend to select the students based on the objective sources such as teachers' observation, recommendation, school scores, but this has limit to find out the real potential genius. China has the similar problems, but they consider of the comprehensive talented and abilities in students at school unit level. (4) Both countries have the teacher training systems for study to make more efficient programs and methods in gited education. It has been emphasized the necessity of gifted education to expand the range and target. Most of all it is very essential to train the teachers to manipulate the gifted education programs. The government should be persue the multiplicity and professionality now. So there are so many things to learn from China since they managed the gifted education in a regular curriculum of the school.

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.
