The purpose of this study is to find out learning content for astronomical observation that could perform astronomical programs regardless of weather conditions as a case for the present conditions of astronomical observation and the methods of new education for astronomical observation, and to suggest the methods of synchronized multiple astronomical observation and actual cases using the Internet network. The results are as follows. First, the method of galaxy-oriented astronomical education helped those attempting to approach astronomy academically for the first time grasp useful concepts as to the astronomical space, and let them look at the space in an objective sense, which was effective in forming cosmic structure and concepts. Second, the administration curriculum of astronomical observation team was related to data that systematically contained annual astronomical education concerning the operation of astronomical observation teams; thus, they could be suggested as beneficial teaching materials to the teachers who wanted to organize a school club meeting. Third, it has been noted that the level of students' satisfaction in p2d program and MSO program was very high, and they turned out to be effective learning methods that could be implemented even in times of rain when it would not be possible to conduct astronomical observation activities.

The purpose of this study is to examine the effect of PBL-based astronomical observation on the science process skills and scientific attitudes in elementary science-gifted students. To verify research problems, the subjects of this study were forth-grade students selected from one classes of an elementary science-gifted class in Busan National University of education : the research group is composed of twenty students who were participated in PBL-based astronomical observation program. During four weeks, the PBL-based astronomical observation program instruction was executed in the reasearch group. Post-test showed following results: First, the research group showed a significant improvement in the science process skill. We look into detailly this, the research group showed a significant improvement in the basis science skill. The sub-factor 'expectation' of the science process skill effects a significant improvement. Second, the research group showed a significant improvement in the scientific attitudes. In conclusion, PBL-based astronomical observation program was more effective on science process skill and scientific attitudes. However, since the study has a limit on an object of the study and the applied program, the additional studies need to be conducted with an extended comparative group and program.

The purpose of this study is to develop an astronomy education program reflecting astronomical thinking to be used at science museum and to investigate the effect of the program on the improvement of astronomical thinking ability of high school students. After selecting the components of astronomical thinking through literature studies, we developed an astronomy education program consisting of four stages: demonstration and observation, and question and thinking, support and group discussion, demonstration and assessment. In order to verify the effectiveness of the program, we conducted a covariance analysis on the pre- and post-tests of the experimental group and control group to examine the level of students' thinking before and after using the program in teaching and learning. As a result, it was confirmed that the astronomy education program reflecting astronomical thinking was effective in promoting students' astronomical thinking ability. In particular, this program was effective in enhancing the ability of modeling by reconstructing the observed astronomical phenomenon from the viewpoint of the universe with respect to spatial thinking in the astronomy domain. It was also effective to improve the ability of organizing the system by grasping the relationship between the elements constituting the astronomical system in relation to the system thinking in the astronomy domain. This study is significant in suggesting a specific teaching and learning program to develop students' astronomical thinking.

The purpose of this study was to find out the effects of astronomical STEAM program using co-teaching on self-directed learning attitude. For this purpose, we developed an astronomical STEAM program and applied it to elementary science gifted students. Thirty six, $5^{th}$ and $6^{th}$ grade elementary science gifted students were participated in this study in total having 16 students in experimental group and 20 students in control group. The results were described as follows. First, astronomical STEAM program using co-teaching was effective in improving self-directed learning attitude. Second, the program was effective in improving participants' openness to learning opportunities and problem-solving. Third, students were satisfied with the co-teaching that provided ample feedbacks and detailed explanations, and teachers perceived that co-teaching was helpful to overcome a lack of professional knowledge, and to solve difficulties of evaluation and preparing teaching materials for STEAM classes. With findings, we discussed implications for co-teaching of STEAM lessons to improve students' self-directed learning attitude at the end of paper.

We report the discovery of four quasars with M₁₄₅₀ ≳ -25.0 mag at z ~ 5 and supermassive black hole mass measurement for one of the quasars. They were selected as promising high-redshift quasar candidates via deep learning and Bayesian information criterion, which are expected to be effective in discriminating quasars from the late-type stars and high-redshift galaxies. The candidates were observed by the Double Spectrograph on the Palomar 200-inch Hale Telescope. They show clear Lyα breaks at about 7000-8000 Å, indicating they are quasars at 4.7 < z < 5.6. For HSC J233107-001014, we measure the mass of its supermassive black hole (SMBH) using its C _IV λ1549 emission line. The SMBH mass and Eddington ratio of the quasar are found to be ~10⁸ M_⊙ and ~0.6, respectively. This suggests that this quasar possibly harbors a fast growing SMBH near the Eddington limit despite its faintness (L_Bol < 10⁴⁶ erg s^-1). Our 100% quasar identification rate supports high efficiency of our deep learning and Bayesian information criterion selection method, which can be applied to future surveys to increase high-redshift quasar sample.

The purpose of this study is to develop an astronomical observing education program that enables high school students to inquire the distance of astronomical bodies based on the research methods (observing open clusters and exploring collected big data) using small telescopes and DSLR cameras. After analyzing the 2015 revised science curriculum, we developed science club activity materials and teacher-student learning contents suitable for high school earth science education. A panel of six teachers and researchers of earth science education and astronomy, participated in developing the educational materials. The validity of the program was verified through establishing the agreement among the panels after in-depth discussions and clarifications. The program, developed with 10 lessons in total, showed high satisfactory content validity (CVI, .89) and conformity of school class (Likert's 5 point scales, 4.17). The feedback of the panels and the Delphi analysis continued to improve the quality of the program. The pilot testing result with high school students (N=9) showed that the students' satisfaction rate was high as 4.48. Using the astronomical observational education program of this study is expected to contribute in improving the convergence educational activity, interest, curiosity, and inquiry ability of students in the universe and the astronomical bodies.
