We analyze the admission test problems used in 1998 at the Science Education Center for Gifted Youth at Kyungpook National University (SECGY, KNU). The test consists of two parts, an evaluation of the scientific thinking skills and an evaluation of the achievement for Mathematics and Sciences, the former of which includes evaluations of scientific process skills and logical thinking skills. The problems for the test of scientific thinking skills were developed and standardized by the Korea Education Development Center, while those of the achievement for Mathematics and Sciences were made at SECGY. We calculate the indices of the difficulty and discrimination for each problem to determine whether or not the test is appropriate to apply for selecting number of gifted students among the recommended students from 389 middle schools in Taegu-city and Kyungsang-pook-do Province. We find that both indices of most problems for the test of scientific thinking skills were out range of the appropriate level and. moreover, even those problems which fall into the appropriate range showed very low efficiencies for distractors. We, thus, conclude that the problems of the test of scientific thinking skills are inappropriate to use as a test for admission to SECGY. On the other hand, the problems of the achievement test showed extreme results; the Mathematics problems appeared to be too difficult, whereas the Physics problems appeared too easy. However, overall scores showed a normal distribution, indicating that those problems played crucial role in selecting gifted students. We finally propose several suggestions in developing the test problems and in selecting students at the SECGY.

Teaching aids Robot Education, through early education and contests, is very commonly known to elementary school students, their parents and teacher. However, not only we do not have complete knowledge of how robot education for after school performs, but also we lack a proper management skills in educating new teachers and running a structured program. Thus, through this research, we would like to identify the problems in teacher's knowledge and how the robot education is running according to provinces, size of cities, public private school, and size of schools and provide proper and most effective way of teaching after school robot class. According to the result of this research of running 'Robot class' in different area, sub-areas and size of schools, there was a meaningful difference and the biggest problem in performance was the class organization. In addition, about the expectation through after school classes, the research showed that the teachers expect lower cost of private education and improvement in creativity the most.

수학사는 수학적 사실이나 수학자에 대한 연대기적 나열만을 의미하는 것은 아니다. 수학사에서는 수학적 개념들, 정리들, 연구 방법의 발생, 축적, 그리고 발전에 대한 폭넓은 견해를 접할 수 있다. 특히, 수학사에서 접할 수 있는 수학 문제해결의 다양한 방법은 수학 교수-학습 과정에서 교사의 올바른 교수학적 선택을 위한 중요한 기초 자료가 될 수 있다. 본 연구에서는 그리스의 수학자 아르키메데스가 구의 부피를 구하기 위해 사용했던 공학적 문제해결 방법을 살펴보고, 공학적 방법의 활용에 관련된 수학적 기초를 살펴보고, 공학적 문제해결 방법을 중등학교 수학 영재교육에 활용할 수 있는 가능성을 모색할 것이다.

This survey is to know the present situation and effective alternatives of mathematics gifted education program for the 5-8 grade students in Korea. This is aiming at finding effective ideas useful to the definition of the gifted, the development of the methods and tools for identification, the proper organization of program and urgent issues. The number of collected questionnaire available by mailing is 92; 21 specialists, 24 experienced teachers and 47 scholars who are concerned with the education for the gifted. Not translated original Korean-Questionnaire is in the appendix.

밀러-유리 실험은 1950년대 처음으로 초기 지구의 대기 방전 실험으로 아미노산을 합성한 실험이다. 생명의 기원에 대한 내용이 교과서나 책에 실릴 때마다 빠지지 않고 등장하는 실험으로, 학생들의 탐구 활동 연구주제로 실험을 설계하여 진행하였다. 실험실 설계부터 시작하여 실험 과정인 유리기구 세척, 진공 만들기, 기체주입과 방전실험을 소개한다. 실험 장치가 완성 된 후, 실험 시간 23시간 중 약 4시간 동안 방전하여 갈색 용액을 얻는데 성공하였다. 아민기와 반응하는 ninhydrin 반응에서 양성반응을 보여 아미노산 수용액임을 확인하였다.

The centroid of triangle is physical property but almost mathematics teachers do not teach centroid by the help of experiments an so they have misconception on principle of centroid. In this paper we investigate whether teachers have made an experiment on centroid of triangle, and we check up on the level of understanding on centroid for mathematics teachers. We introduce the method of teaching centroid and study the process of generalization about centroid of triangle for gifted students.

This study is to find the properties of Diffy activity and to investigate the problems and conjectures which could be posed in the Diffy activity. The Diffy is a simple subtracting activity. But, 1 think it is a field where the mathematical thinking can take place. I proposed some problems and conjectures which can be posed. I solved the problems using excel and the software I developed and proposed the related data. I think such problems and the data will be the good materials for elementary students and gifted to think mathematically with.
