The gift program developed at KEDI is based on Enrichment Triad Model. The output of the students who completed Enrichment Triad Model has to be new and useful in creative knowledge. However, most of the students' output has been the summaries of what is learned that they were not creatively developed as experts' would be. Thus, this study follows the KEDI's guideline for developing gift program so that it could give suggestion on how to develop students' research skills when developing and applying gift program.

Currently, the robot is widely utilized in various educational settings such as after-school classes, and special classes for gifted students. The robot is widely recognized as a useful tool for helping students solve problems. The core activities of programming learning with robot need to provide various problem contexts to the students and guide students' problem solving process. Students gain cognitive and affective benefits when they solve problems with robots. This paper describes the impact of programming learning using robot based on schoolwide enrichment model on elementary school students' creative potential. As a result, the students of experimental group than the students of the control group improved creative personality and ideational behavior, and the gifted students of experimental group than the gifted students of control group improved ideational behavior.

Development of Learning system and learning activity based on web in accedence with development of information communication technology are active. From teaming system with web, teaching-teaming data for student's leaning level is not systematic and interactions between students and teachers are insufficiency. Only result of teaming evaluation is showed not supply reason what is correct or not and there is no relationship or linking deeping teaming. In this paper, we tried to improve the interaction between teachers and students by analyzing study system through virtual system on high school's Introduction to computer science. And we designed and implemented the WBI system Using ASP, the system is maximize the effect of study related to further study. It will improve the feedback between the teachers and the students and help the learners enlarge the faculty of comprehension ability.

This paper studies on introduction of online education to provide opportunities for spreading university-level program by analyzing perception of high school students and teachers. The university-level program can be defined as the fulfillment of learning needs and the value offer of excellence education for outstanding high school students who want to improve their potential capabilities. For the study, a survey was conducted at high school students and teachers. As the result of the survey for high school students, the efficiency of education was the most important factor for the university-level program. The order of next important factors was the aid to entering university, the method of education, the satisfaction, and the recommendation of others. The result of high school teacher indicated that the efficiency of education was the most important factor as the high school students. The order of next important factors by high school teachers was the satisfaction, the aid to entering university, and the method of education. An activation of the university-level programs can be spread by analyzing the results of the survey. With the introduction of online education for the university-level program can conclude the guarantee of the right of studying and the reduction of education gap. This paper proposed an online education for the university-level program to guarantee the right of studying and to reduce the education gap.

Geometry having long history of mathematics have important role for thinking power and creativity progress in middle school. The regular polygon included in plane geometry was mainly taught convex regular polygon in elementary school and middle school. In this study, we investigated the denotation's extension of regular polygon by mathematical basic knowledge included in school curriculum. For this research, first, school mathematical knowledge about regular polygon was analyzed. And then, basic direction of research was established for inquiry. Second, based on this analysis inductive inquiry activity was performed with research using geometry software(Cabri Geometry II). Through this study the development of enriched learning material and showing the direction of geometry research is expected.

The purpose of this study is to analyze the contents of pi of Chosun-sanhak and organize the teaching and learning activities to help to understand the concept of pi deeply using the analysis results. The results of this study are as follows. First, Chosun-sanhak used various approximate values of pi and those were represented as the form to reveal the meaning of the ratio of radius and circumference. Second, There were the freedom of selection of the approximate values of pi suitably. Lastly, the enriched leaning about pi need to draw a distinction pi from approximate values of pi, choose the suitable approximate values of pi and compare the method of calculation of circumference and the area of circle of Chosun-sanhak and today's mathematics. In conclusion, I proposed several issues which is worth exploring further in relation to pi and Chosun-Sanhak.

The purpose of this study was to find out the characteristics of learning contents structure of K-12 science textbooks. The characteristics are related to 7 main concepts of matter properties; reaction rate, other reaction, density, solution, state change, absorption, and surface property. The contects are analyzed into 5 types of characteristics; type of concept extension, type of concept deepness, type of same level concept, type of confusion with other concepts, and type of concept interruption. First two types are positive content structures, but the others are negative structures. The findings are as follows. First, a lot of learning contents have the characteristic of 'type of same level concept'. There are few which have the characteristic of 'type of concept deepness'. Second, there are a lot of concepts related to 'properties of matter' which are not represented any more in middle and high school science textbooks. Those concepts are importantly taught in early childhood education and elementary school science. Most of the learning contents don't represent 'type of concept deepness'. Therefore the science textbooks needs to be restructuring.

본 논문에서는 과학영재교육원 초등심화 수학 정보 과정의 30명을 대상으로 프로그래밍 학습을 수행한 후 사회성의 변화를 분석하였다. 수업에서는 교육용 프로그래밍 언어인 스크래치의 리믹스 기능을 활용하였으며, 협동학습이 가능하도록 동료 학습자의 프로젝트를 수정 보완하도록 하고 최종적으로 팀 단위의 결과물을 도출하였다. 연구결과에 따르면, 스크래치의 리믹스 기능을 활용한 프로그래밍 학습이 사회성 향상에 통계적으로 유의미하며, 사회성 구성 요소인 사교성, 자주성, 협동심에서 긍정적인 효과가 있는 것으로 나타났다.
