The 7th science curriculum has the characteristics of humanistic philosophy of education. The humanistic curriculum emphasized learner-centered education, which claims to stand for learners' experiences. This study searched for the significances of the 7th science curriculum, and discussed its tasks and perspectives based on the backgrounds, characteristics, and objectives mentioned in the history of reforming science curriculum. The 7th science curriculum emphasizes learners' experiences and everyday life materials are favored in teaching-learning activities. For the desirable effects related to this commitment, pre-service and in-service training programs are required about the social elements in the nature of science, and everyday life contexts should be examined in views of educational and cognitive perspectives, so the contextual differences between science and everyday life should be clarified.

In this study, the scientific description of Earth was analyzed by targeting the item titled '1. Introduction to the Earth World', which is part of the 'first section' of SeoYuGyeonMun(西遊見聞) written by Yu Giljun(俞吉濬). This part served as an introduction to the entirety of SeoYuGyeonMun. It was also one of the earliest documents in Korean literature to mention 'the earth as a celestial body', rather than solely focusing on it as land which was a departure from traditional thinking. Yu Giljun made deliberate efforts to translate the concept of Earth's rotation into "Jashinjeon(自身轉)" and Neptune as "Haeryongseong(海龍星)". He included the latest scientific debates and facts in SeoYuGyeonMun, such as the theories of Western scholars explaining the types of seismic waves and discussions at international conferences related to the establishment of the original meridian. Yu Giljun, who was not a science major, would have used HunMongGungRiDoHae(訓蒙窮理図解, 1868) written by Fukuzawa(福澤諭吉) and GeokmulJiji(格物地誌, 1876) which was translated by Matsumoto(松本駒次郎) as references to describe scientific descriptions. The contents described in 'Introduction to the Earth World' cover the foundational composition and subject matter that are typically found in modern-day Earth science textbooks.

The purpose of this paper is to identify college students' conceptions of the earth system cycles as learners of earth science education (ESE) and draw educational implications. An eight-week creative story writing project was held with 62 non-science students taking a general course on earth science. Their creative stories were categorized by analyzing the conceptions and types of cycle with a story mapping technique. The cycle conceptions of earth systems were expressed diversely into 32; most of the cycle types were circular and complex, while the others were branch-shaped and linear types that fail to complete the cycles. College students' conceptions of the earth system cycles is biased toward natural-abiotic systems; less than 30% of them are shown to be aware of all three categories: natural-abiotic, natural-biotic, and human systems. It is essential to diversify the content of education on earth system cycles and help learners develop systematic methods of thinking so that they will be able to recognize the impacts of feedback from human activities through ESE.

The purpose of this study is to suggest improvements in the science concepts and inquiry activities presented in the earth science section in the 2015 revised curriculum elementary science textbooks. For this study, two science educator and three elementary school teachers developed a survey questionnaire to investigate science concepts, inquiry activities, and suggest improvements. The survey was conducted two times, and 30 elementary school teachers and three earth science professors (geology, meteorology, astronomy) participated in the survey. As a result, it was investigated that eight concepts in the solid section, three concepts in the fluid section, and one concept in universe and integration section contained misconceptions. It was investigated that the content of inquiry activity needs to be supplemented, with seven elements in solid section, three elements in fluid section, and one in the universe and integration section. According to the research results, if the textbook is revised, it is necessary to accurately confirm the science concepts or content of inquiry activities. Also in the case of science concepts presented in textbooks, it will be necessary to consider not only the scope and sequence of contents but also the process of learning progression.

제7차 교육과정에 따라서 집필된 지구과학 I, II 교과서와 국내외 각종 지구과학 교재의 지질 연대 자료를 검토하였다. 지구과학 I, II 교과서의 자료는 대부분 최신의 자료가 아니며, 많은 자료들은 지질학 원론과 지구과학 개론 등의 국내 대학 교재에 제시된 수 십년 전의 자료를 그대로 따랐다. 또한 외국 대학의 지구과학 또는 지질학 개론서의 경우에서도 유사하게 수 십년 전의 자료를 제시하고 있다. 최근 국제 층서 위원회(ICS)에 의하여 연구 제시된 국제 층서 챠트(ICS 2000), 국제 지질 연대표(IGTS 2003) 및 지질 연대표(GTS 2004) 등의 많은 새로운 자료들이 제시되어 있다. 새로운 자료 중에서 중요한 것들에는 신생대의 고제3기와 신제3기, 석탄기의 미시시피아세와 펜실베니아세, 원생이언의 고원생대, 중원생대 및 신원생대 그리고 시생이언의 시시생대, 고시생대, 중시생대 및 신시생대를 들 수 있다. 이들 새로운 지질 연대 자료는 새로운 지구과학 교과서 집필시 인용되어야 할 것이다.

In this study, we apply a lesson design process using an argumentation structure to preservice earth science teachers and analyzed argumentation levels displayed in the lesson plans written by preservice teachers in the process. As a result of the study, the preservice teachers designed a logically structured lesson by reflecting more argumentation components in the final lesson plan than the first one. In addition, in the case of lesson topics in which all argumentation elements were not explicitly presented in textbooks or curriculum, preservice teachers could not clearly reflect some argumentation components in the lesson plan. The conclusions and implications based on the results are as follows: First, it is necessary to use the argumentation structure as a tool to design logical science lessons, considering that argumentation levels of lesson plans written by preservice science teachers were improved by using argumentation structures in instructional design. Next, it is necessary to cultivate the preservice science teacher's ability to reconstruct the curriculum for science lesson design using the argumentation structure since argumentation levels of lesson plans written by preservice science teachers were limited to the argumentation components presented in the textbook and curriculum. Additionally, it is necessary to develop and apply a preservice teacher education program that uses the argumentation structure in the context of actual teaching activities so that preservice science teachers can not only understand argumentation but also improve their class expertise.

The purpose of this study was to determined the conceptual structure used by earth science teachers to classify metamorphic rocks as well as the criteria applied in the process of classifying metamorphic rocks. To this end, the researchers collected verbal data uttered in the process of classifying metamorphic rock using think-aloud from 21 earth science teachers in middle and high schools in Jeollabuk-do, Republic of Korea. The collected verbal data were analyzed using the semantic network analysis method, and the following results were obtained. First, in the process of classifying metamorphic rocks, earth science teachers classified them based on characteristics such as color, compositional minerals, and particle size, which can be generally observed in rocks, and foliation that appears in metamorphic rocks. Second, earth science teachers recognize the classification criteria for metamorphic rocks and focus on metamorphism such as contact metamorphism or regional metamorphism. However, there were cases where rocks were mistakenly classified through incorrect identification. Therefore, it is necessary to provide sufficient observational information about, and experience of, metamorphic rocks to enable earth science teachers to recognize and relate to the scientific process of identifying metamorphic rocks through the phenomena observed.
