The purpose of this study was to investigate the correlation among science gifted students' self-reported knowledge and self-perceived importance about Earth systems, and their science motivation. Ninety three seventh graders participated in this study who enrolled at Science Gifted Institute of K university. The correlation was measured by a validated Earth systems survey and Science Motivation Questionnaire (SMQ). The data were analyzed at the margin of error probability 0.05 using correlation and regression analysis. The result of reliability for items turned out high because the Cronbach's alphas were .896~.937. Results indicated that the correlation between self-reported knowledge on Earth systems and science motivation showed a correlation coefficient .656, whereas the correlation between importance on Earth systems and science motivation was .387, which was regarded as low. On the other hands, the result of regression analysis depicted that non-std. coefficients between students' self-reported knowledge about Earth systems and science motivation were .548 (.077), which lead to the conclusion that students' knowledge on Earth systems explained 43% of science motive-variation. It implied that Earth systems education program could impact the increased motivation of science gifted-students. Therefore, this study suggests that the various Earth systems education programs could be developed and implemented in order to increase students' motivation on studying science in general and Earth science in specific.

This study aimed at identifying the characteristics of current Earth Science Curricula in several countries in terms of their format, objectives and contents and discussing about them. The curricula(including textbooks) were collected from 6 countries The United States of America, England, Australia, Japan and The Republic of China. Here are the results of this study ; 1. Earth Science should be teached in high school and assigned at least 8-10 unit. 2. In Earth Science objectives, scientific inquiry methods through observation and experiment and mutual relationship among science, technology and society must be stressed. 3. The contents of Earth Science must did with experimental and activity rather than understanding in order to induce students to how more intersts in Earth Science. 4. There is a growing tendency for Earth Science Education to be attached importance to life environment and career education.

This research is aimed to examine the differences through comparative analysis of the Earth Science contents in the science textbooks between Korea and DPRK. The contents of level and scope in science textbooks between Korea and DPRK are analysed by TIMSS frameworks. The results of this research are as follows : 1. The science textbooks of DPRK is lower in quality of paper, printing to that of Korea, and the illustrations, editing design in the textbooks of DPRK are fewer, monochromic and monotonous while those in Korea. 2. The contents of Earth Science in DPRK's science textbooks rank 37.0%, but those of Korea's science textbooks rank 25.5% of the whole textbooks. The learning units related to Earth Science are generally similar to the level and scope in science textbooks between Korea and DPRK. The type of inquire activities in the textbooks of DPRK largely takes on the model experiment, and it was shown that the number of experiments directly made by children is very small compared to Korea' textbooks. 3. There are lots of differences in Earth Science learning terms and predicates used in the textbooks between Korea and DPRK.

The purpose of this study is to explore the applying possibility of the Earth Systems Education(ESE) in elementary school science education through the improving of students' recognition with the earth systematic nature by systems thinking education - for this was the recognizing as earth systematic nature was the key element of ESE, and the systems thinking skill is accredited very effective tool for the understanding with earth systematic nature. For this, the systems thinking's teaching-learning programs were developed and applied to the 6th students (21s) for 10hours' classes. The results of this study are as follows; In most of the 6th students didn't recognize with earth systematic nature from a lack of understanding of the vapor being in every nature environments. In systems teaching-learning classes, most of students participated positively in learning activities and achieved the aim of a lesson. In the testing results for students' recognition improving to earth systematic nature after the systems thinking education, about 24% students were showed the improving results of the recognition with earth systematic nature. Consequently, It is suggested that just as the achieving of the points of ESE in elementary school science education, the approaching method of the systems thinking education is worth attempting to applying of the ESE.

The purpose of this exploratory study was to investigate the influence of pre-service science teachers' selection of earth science I, II in the high school and their college major on their self-perceived attitude and academic achievement in general earth science lecture at university. The participants in the study were 273 who enrolled in the division of science education, college of education and took the general earth science lecture from 2012 to 2015. The data was analyzed with two-way ANOVA by using SPSS 23.0. The results indicated that there was no significant difference of students' attitude and examination difficulty in general earth science lecture between earth science major and other subject major. However, students who took earth science I and/or II in high school showed positive attitude toward the lecture and higher achievement scores than students who didn't take earth science I, II in their high school. The results of the study imply that it is essential to consider students' attitude toward science and achievement in pre-service science teacher education.

In this study, we propose research methods to explore the nature of earth science by applying the phenomenological approach and NOS-family resemblance approach based on literature review. The phenomenological approach exploring the nature of earth science is a method of collecting, analyzing and synthesizing multifaceted features of earth science from intuitive sensory phenomena without prejudice. As a way of exploring the nature of earth science from a phenomenological point of view, we propose the NOS-family resemblance approach to the NOS. This approach provides a comprehensive explanation of NOS by combining the characteristics shared by different areas of science with distinct differences. Applying this method to exploring the nature of earth science, we can identify both domain-general and domain-specific characteristics that make sub-areas of earth science a 'family.' For example, through the networking of features shared by such sub-areas as geology, atmospheric science, oceanography, astronomy, earth system science, etc., we can extract the family-resemblance characteristics that make these sub-areas a family called earth science. Through these approaches to the nature of earth science, the richness, complexity, and dynamic nature of earth science can be revealed as a whole. In addition, we will be able to grasp the change in the sub-areas that constitute the earth science, which in turn changes the nature of earth science, and to contribute to establishing the status and development system of earth science as a school subject.

The atmosphere strongly affects the Earth's spin rotation in wide range of timescale from daily to annual. Its dominant role in the seasonal perturbations of both the pole position and spinning rate of the Earth is once again confirmed by a comparison of two recent data sets; i) the Earth orientation parameter and ii) the global atmospheric state. The atmospheric semi-diurnal tide has been known to be a source of the Earth's spin acceleration, and its magnitude is re-estimated by using an enhanced formulation and an up-dated empirical atmospheric S2 tide model. During the last twenty years, an unusual eastward drift of the Earth's pole has been observed. The change in the Earth's inertia tensor due to glacier mass redistribution is directly assessed, and the recent eastward movement of the pole is ascribed to this change. Furthermore, the associated changes in the length of day and UT1 are estimated.

The purpose of this study is to investigate Earth Systems Education, its matter and also its possibility of practical application in Korea. Some attempts are made to see the value of the Earth Systems Education. Adopting two kinds of Korean science textbooks of middle school and activity of Earth Systems Education were analyzed. The interview with teachers is implemented for the study on objective, the structure of matter and teaching strategy in Earth Systems Education. The program is given to 96 students(2 classes, the first grade at middle school). To analyze the effect of Earth Systems Education program, students were interviewed by their teacher. The conclusions of this study are as follows: 1. The Earth Systems Education is contributed to the way to enable students to have a cognitive perspective about the earth and to look for the nature. Earth Systems Education is to use interdisciplinary approaches for integration in science. 2. The result of analysis in the contents of Korean science textbooks, the viewpoints about Earth Systems Education were not found, but the accounts about the interactions among subsystems were found. 3. According to the results of interview with teachers, they approve of system approach, the structure of matter and teaching strategy of Earth Systems Education. 4. According to the results of interview with students, they understand the interactions among subsystems which are elements of Earth Systems. As a results, Earth Systems Education is a effective method for informed judgements about Earth and science and manner for work for integration in science curriculum. So Earth Systems Education be applied to science education in Korea.

This study aimed to explore how to characterize the earth science inquiry in schools in terms of science teaching interaction and constructivist teaching practice. The constructivist teaching practices were analyzed with Reformed Teaching Observation Protocol (RTOP) in three aspects including (1) student oriented class implementation, (2) subject knowledge and representation, and (3) classroom communication. Fourteen earth science classes were observed and scored with RTOP. The class was evaluated to be transitional stage in terms of constructivist teaching, e.g., moving toward student-centered teaching practice. Especially, Korean teachers tend to lean their classes more on propositional knowledge than procedural knowledge. To interpret science teaching interactions, an earth science teacher with a RTOP top rank was selected. Her class was then videotaped for detailed analysis. I adopted the analytical framework of communicative approaches and discourse patterns among the five aspects of interactions presented by Mortimer and Scott (2003). It was found that this earth science teacher used more authoritative patterns than the dialogic. In addition, she used IRE discourse pattern more frequently. Interestingly, teachers interacted with their students more frequently in the form of repeated (or IRE chain pattern), that is IRFRF (teacher initiation-student response-teacher feedback-student response-teacher feedback) in the context of dialogic communicative approaches, while simple IRE occurred in an authoritative approach. In earth science classrooms, typical interaction may well be constructed in the form of IRFRF chains to allow students free conjectures and abduction.
