Astronomy is one of the recurrent comtemporary issues in the mass media where news related to comets, new exoplanets, satellites, space tests, etc., frequently appear. From this perspective, students at all levels are especially motivated to learn astronomy. Nevertheless, students’ interest does not improve their astronomical knowledge, which leads students’ difficulty in understanding astronomy in school science. In this context, we felt the need to review astronomy education research trends in domestic and other countries, especially focused on the education programs. The purpose of this study is to analyze and compare the program characteristics during last three decades. The total number of analyzed cases is 88(89 for double counting). As a result, we found different characteristics of program types and learning methods between Korea and other countries. Based on the results of this study, we suggested the direction to improve the astronomy education in Korea.
