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.

In this study, a block-base coding that could develop computing thinking was applied to Earth science teaching and learning to identify how the perception of computational thinking and scientific attitude was changed as part of creativity education. Based on the results of the study, the conclusions are as follows: First, an Earth science education program was developed using a block-based coding for elementary school students. The 12-hour program was designed for inquiry activities to encourage students to engage in various thinking by providing them with activity-oriented problems. Second, the Earth science education program using a block-based coding showed significant results in confidence in the use of a computer program, integrated learning with a computer, computational thinking, and problem-solving factors with computational thinking. Third, the Earth science education program using block-based coding showed significant differences in the categories of curiosity, criticism, cooperation, persistence, and creativity. It could be judged that it was effective for students in the process of questioning and trying to solve the problem themselves.

This research was conducted with an intention to develop a teaching program that possesses a goal of elevating higher thinking ability within the science class and to investigate its effect. The hypothetico-deductive teaching model was developed and its' program was designed to be directly put into the practical use, and apply it in class. The application of the hypothetico-deductive teaching program had a positive effect in the improvement of students' creative thinking ability and critical thinking ability. And it had a positive influence on scientific attitudes. After completing the program the opinions of the students who participated in this research by a poll were gathered and analyzed. The students felt uneasy and had a lot of difficulties during the program activity because they had to keep on thinking newly, critically, and scientifically, but they admitted that they gained the ability to think on their own when the program was completed.

The purposes of this study are 1) to develop a pre-education program for teaching the basic concepts of systems thinking and STEAM program based on systems thinking and 2) to investigate the effects of the program on middle school students' systems thinking. The subjects were 4 seventh-graders and 4 ninth-graders in a middle school located in the province of Gyeongsangbuk-do. Data related to students' systems thinking was analyzed using the rubrics developed by Hung(2008). The results were reviewed by experts to verify the validity of the rubrics and the reliability of students' system thinking. In addition, the data analyzed with the rubrics, students' awareness of systems thinking, word associations, causal maps and interviews were systematically analyzed to investigate the effects of the program on students' systems thinking. The findings of this study were as follows: First, a pre-education program and teachers' guidebook for teaching and learning the concept of systems thinking and causal maps were developed. The pre-education program consisted of familiar TV entertainment program-Infinite Challenge (Muhandojeon)-with a theme of Global Warming. Second, a STEAM education program based on systems thinking which was composed of 5 steps: Analysis-Design-Build-Assessment-Systems thinking. The major theme of the program was an air extinguisher. The developed STEAM education program had positive effects on improving middle school students' systems thinking abilities such as understanding systems, relations within a system and system generalization. Therefore, it was concluded that the STEAM program could be instrumental for cultivating students' STEAM literacy with improved systems thinking.

The purpose of this study was to investigate the general transfer effects of Thinking Science program on the problem solving with compensational reasoning of the elementary school students. For this study, 156 5th grade and 138 6th grade students were selected from four elementary schools. The students were tested with SRT(Science Reasoning Task) and compensational reasoning task. Statistically significant gains on the development of compensational reasoning were shown by the experimental group implemented with Thinking Science activities compared to the group implemented with compensation activity only. The achievement of the experimental group was higher than that of the compensation activity group in solving problem with compensational reasoning, specially for the boys and students in both the mature concrete and the concrete generalization stage. The results of this study implied that implementation of Thinking Science program related to several formal reasoning were effective for the development of reasoning ability as a general-transfer.

The purpose of this study was to investigate the effects of Thinking Science program on the cognitive acceleration and cognitive processing skills of the elementary school students. Subjects included 305 5th grade students in three elementary schools. Subjects were divided into the experimental and the control groups. Thinking Science program was implemented to the experimental group over a period of two years. Statistically significant gains on the cognitive acceleration were shown by the experimental group compared with the control group. The intervention effects on the cognitive acceleration were shown for the girls of the elementary schools. It was also found that Thinking Science program exerted significant effect on the development of the cognitive processing skills of the students. The experimental group gained higher scores of attention and simultaneous processing skills compared with the control group. This implied that Thinking Science program was effective not only on the cognitive acceleration but also on the development of the cognitive processing skills as a far-transfer.
