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.

Geological information on the Korean Peninsula plays a significant role in science education because it provides a basic knowledge foundation for public use and creates an opportunity to learn about the nature of geology as a historical science. In particular, the Mesozoic Era, when the Korean Peninsula experienced a high degree of tectonic activity, is a pivotal period for understanding the geological history of the Korean Peninsula. This study aimed to analyze whether content regarding the geology of the Mesozoic Era are reliably and consistently presented in the 'Geology of the Korean Peninsula' section of Earth Science II textbooks based on the 2015 revised curriculum. Four textbooks for Earth Science II were analyzed, focusing on the sedimentary strata, tectonic movement, and granites of the Mesozoic Era. The analysis items were terms, periods, and rock distribution areas. The consistency within and among textbooks and of textbooks and scientific knowledge was analyzed for each analysis item. Various inconsistencies were found regarding the geological terms, periods, and rock distribution areas of the Mesozoic Era, and suggestions for its improvement were discussed based on these inconsistencies. It is essential to develop educational materials that are consistent with the latest scientific knowledge through collaboration between the scientific and educational communities.

This study aimed to analyze the conception of an extra-solar planet perceived by university students. To conduct this, we developed an extra-solar planet education program and questionnaires which help to figure out changes between before and after the program, and then applied them to the targeted students. The results of the study are as follows. First, as to the conception of an extra-solar planet, participants understood it merely as a planet outside the solar system before they got training. However, they expanded it to the one revolving around a star that appears outside the solar system based on keywords after the training. Second, they gave brief responses regarding exploration strategies (e.g., observing the extra-solar planet by using the Doppler effect, dietary phenomenon, and gravitational lens) based on indirect experiences they encountered in the media. The responses indicated their lack of concept of the extra-solar planet exploration methods. However, their recognition of the extra-solar planet observation became concrete while students learned about the exploration of the extra-solar planet. Third, they were expanding the importance of the exoplanet observation simply beyond the discovery of extraterrestrial life to the creative process and research methods, including the solar system and the development of humanity. Fourth, they recognized that exoplanet education is necessary for curriculum as it will be able to bring about students' interest and curiosity as well as scientific knowledge if contents related to the extra-solar planet appear in the earth science curriculum.
