  • The purpose of this study is to provide meaningful basic materials for organizing a science curriculum in future by analyzing the status and changes of contents about astronomical phenomena in textbooks according to the changes of the science curriculum of elementary school. A main target of analysis is science textbooks of elementary school in curriculums from 1st to 7th. For the analysis, the analytic frame based on contents in astronomy textbooks of teachers colleges and colleges of education was used. The result of the analysis is as in the following. First, astronomy accounted for average about 7% of all pages of textbooks in all of science curriculums. The 1st educational curriculum had the most learning quantity of 10.40%, and the 6th curriculum had the least quantity of 4.39%. These results show that astronomy was not a small part and was considered important in each science curriculum of elementary school considering that earth science accounted for 17-26% of all pages in elementary school science curriculum. Second, the things that have been dealt with in common in all science curriculums from 1st to 7th of elementary school are the shape of the earth, the rotation and the revolution of the earth, the occurrence of the seasons, the apparent motion of the sun, the status and motion of the moon, the movement of a star, the brightness and distance of a star, constellations, the sun, planets and others. These contents are expected to be dealt with continuously as basic contents to organize astronomy regardless of the changes of curriculum. Third, in science curriculum of elementary school, astronomical phenomena based on life experiences regarding the earth, the moon and the sun are mainly dealt with in the first and the second grade. Contents requiring principles-understanding and research are dealt with in the fifth and sixth grade. These results show that elementary school science curriculum dealing with astronomy reflects the developmental stages of students and considers principle of learning possibility.

  • 이 연구의 목적은 천문학적 사고를 반영한 과학관 천문교육 프로그램을 개발하고, 그 프로그램이 고등학생들의 천문학적 사고 능력의 향상에 미치는 효과를 확인하는 것이다. 문헌 연구를 통해 천문학적 사고의 구성 요소를 선정한 후 사고력 학습 발달 모형을 응용하여 시연과 관찰, 문제 제시와 사고 활동, 지원과 모둠 토의, 시연과 평가의 네 단계로 구성된 천문교육 프로그램을 개발하였다. 이 프로그램의 효과를 검증하기 위하여 실험군과 대조군의 사전, 사후 검사에 대해 공변량 분석을 실시하였고, 프로그램을 이용한 교수 학습 활동의 사전과 사후에 학생들의 수준 변화를 살펴 보았다. 연구 결과, 천문학적 사고를 반영한 과학관 천문교육 프로그램은 학생들의 천문학적 사고를 증진시키는 데 효과가 있는 것으로 확인되었다. 특히 이 프로그램은 천문 영역의 공간적 사고와 관련하여 관측된 천문 현상을 우주에서 보는 관점에서 재구성하여 모델링하는 능력을 신장시키는 데 효과가 있었고, 시스템 사고와 관련하여 천문 시스템을 구성하는 요소들 간의 관계를 파악하여 시스템을 조직할 수 있는 능력을 향상시키는 데 효과가 있었다. 이 연구는 학생들의 천문학적 사고를 발달시키기 위한 구체적인 교수 학습 프로그램을 제시하였다는 데 그 의의가 있다.

  • There is no doubt that science -and, therefore, science education- is central to the lives of all (NGSS, 2013). This manuscript focuses on ideas in astronomy that are at the foundation of elementary students' understanding of the discipline: the apparent motion of the sun explaining the day / night cycle on Earth. According to prior research demonstrating that neither children nor adults hold a scientific understanding of the big ideas of astronomy (NRC, 1996), understanding of concepts may base students' progress towards more advanced understanding in the domain of astronomy. We have analyzed the logic of the domain and synthesized prior research assessing children's spatial representation from an earth- and a space based perspective to develop a set of learning trajectories that describe how students' initial ideas about apparent celestial motion as they take school science can be build upon. In this study elementary students' representations were compared by their resident context including urban and rural. This study may present a first look at the use of a learning progression framework in analyzing the structure of astronomy education. We discuss how this work may eventually lead towards the development and empirical testing of how children learn to describe and explain apparent patterns of celestial motion.

  • A series of high resolution spectra of CH Cygni obtained at the Bohyunsan Optical Astronomy Observatory (BOAO) in April 2004 has been analyzed. The emission components of the [O I] 6300 A lines are de-convoluted and fitted with Gaussian functions in order to investigate the characteristics and the structure of CH Cygni system along with the analysis for $H{\alpha}$ and [O III] lines. A present geometrical structure of the components of CH Cygni system is suggested.

  • A total of 842 observations (277 in B, 282 in V, and in R) for U Pegasi were made in October of 1996 at Mt. Sobaek Observatory. With our data we constructed the BVR light curves and determinded 5 times of minimum light. We also obtained physical parameters of the system by combined analysis of both light and radial velocity curves using the Wilson-Devinney code.
