  • The purposes of this study were to analyze high school students' understanding about the Earth system and systems thinking process, and to develop science writing programs designed to assess students' understanding about themes of Earth Science such as global warming, volcanoes, and desertification. A total of 8 $11^{th}$ grade students from general high schools participated in the writing program and draw the causal maps. The methods of this study are as follows. First, DAET-C was used to investigate the way of students' understanding about the Earth systems. What the students' best understood was the component of the Earth systems followed by the interaction of the Earth systems and the scientific literacy of Earth science. Second, feedback circulations on the causal maps were found in four students in global warming section, one student in volcanic eruption section, and four students in desertification section, which means that systems thinking was not largely employed by the students. Consequently, the student participants understood that the global change was happening in correlation with complex concepts and factors, but they were short of using systems thinking in their science study. Therefore, the result of this study suggests that more studies be conducted to develop systems thinking in Earth Science learning through science writing programs.

  • Inquiring earth science phenomena is characterized by the followings: a big scale of time and space, inaccessibility, uncontrollability, and complexity. Thus, it is very difficult or, in some cases, impossible to investigate them through the actual manipulation in laboratories. Therefore, it is necessary to provide chance for students to experience scientific inquiry without actual manipulation in earth science classes. This study is to explore the role of reasoning based on a thought experiment as a representative model without actual manipulation, and to investigate features of various inquiry models using reasoning in classes. We can make implications when applying for applying each inquiry model to earth science classes, proposing a reasoning-based inquiry model embedded in earth scientific phenomena.

  • Graph is a major aspect of science textbooks. In this study, we investigated graph types and characteristics used in high school earth science subject by comparative analysis of science textbooks. The results of the analysis revealed that line graph and contour map was the most widely used graph types in earth science. Among line graphs, multiple line graph and YX graph was dominant. Comparing earth science graphs with other science graphs, earth science graphs exhibited superior in the number and variety. In earth science graphs, the portion of line graph was small, but the portion of contour map and scatter graph was larger than that of other science graphs. YX graph was the most specific graph type in earth science textbooks. The results of our study have implications for reform in function and structure of graph. We suggest that future studies be focused on students' ability of earth science graph interpretation.

  • This study is to search the problems of schoolyard teaching material developed by pre-service earth science teachers and the critical factors affecting material making. The 258 schoolyard teaching materials was collected from 54 pre-service earth science teachers (male: 18, female: 36) major in Earth Science Education in Jeonju, Korea. The schoolyard teaching materials was greatly influenced by making process type of it and the prior knowledge of pre-service earth science teachers. As schoolyard preference exploratory type rely on their prior knowledge to develop the schoolyard teaching materials, they made use of the limited concepts like fault in material making. But the concept preference exploratory type made use of concepts not accessible to majority of pre-service earth science teachers because they selected a concept from the earth science textbook first of all. The pre-service earth science teachers having wrong prior knowledge selected inappropriate resources, as well as fell into the error of concept connecting. The pre-service earth science teachers having right prior knowledge partly considered only shape of resources, but had a disregard for formation process of it in material making. Accordingly, we need to reflect richly Geological Field Trip and Solid Earth Science to curriculum for earth science teacher education. And we have to educate pre-service earth science teachers to create holistic concept on the geological subject matter knowledge, field based teaching and learning strategy, material making process.

  • In the celebration of the $50^{th}$ anniversary of the Korean Earth Science Society, the whole articles published in Journal of the Korean Earth Science Society (JKESS) were quantitatively analyzed. JKESS has played a major role in exchanging academically among earth science education specialists and in educating next generation for the last 36 years since it was founded in 1979. The total number of 1544 articles in thirty five volumes about the earth sciences and the earth science pedagogy has been published by August, 2014, and the number of the yearly published articles has been increasing. Regarding the research area, 69.3% was published in earth sciences and the other 30.7% was in earth science education; the percentage of research articles in geology, atmospheric science, environmental science, oceanography, and astronomy was 55.2, 17.6, 16.0, 6.0, and 5.2%, respectively. The number of research articles on atmospheric science and environmental science has recently been increasing, whereas, earth science education research articles have been" decreasing, which was similar to the pattern seen fifteen years ago. We thought that one of the reasons was related to a new journal named, "Journal of the Korean Society of Earth Science Education" started to publish in December, 2008. The number of articles authored or co-authored with foreigner scholars was totaled 53, which is only 3.4% of the entire number of published articles. It suggests that international advertisement via public relations as well as the development of English homepage be necessary. In order to become an excellent registered academic journal, it is the time to comprehensively discuss how to improve both the quality growth and the quantity of JKESS. According to the Ministry of Education, it is now in its planning stage to convert the current registration system of the academic journals to the autonomous evaluation system in academia. Therefore, we recommend that Journal of the Korean Earth Science Society be prepared for the upcoming future change.

  • Numerical data of the geological time scale in Earth Science I, II textbooks and those of University textbooks of Korea and other countries are briefly reviewed. Numerical data of the geologic time scale shown in Earth Science I, II textbooks are mostly out of date and many of them follow those in the University textbooks of Korea. The same situation is apparent for introductory Earth Science or Geology textbooks of other countries as old data exist in their text books as well. There are many new data in the International Stratigraphic Chart (ISC 2000) and International Geologic Time Scale (IGTS 2003) recently updated by International Commission on Stratigraphy (ICS) and A Geologic Time Scale (GTS 2004). Among the new data, some important things are Paleogene and Neogene Periods of Cenozoic Era, Mississippian and Pensilvanian Epochs of Carborniferous Period, Paleoproterozoic, Mesoproterozoic, and Neoproterozoic Eras of Proterozoic Eon, and Eoarchean, Paleoarchean, Mesoarchean, and Neoarchean Eras of Archean Eon. These new data should be used in the new Earth Science textbooks.

  • Teachers play key roles in classroom instruction. The perceptions and orientations of teachers about teaching have substantial effect on the practical context of science teaching. Analyzing science teacher's perceptions and orientations about Earth Systems Education (ESE) offers an opportunity to figure out how the goals of ESE might be dealt with. In this study, lesson plans developed by and in-depth interview results with two teachers were analyzed in terms of ESE perceptions. ESE orientations were also investigated in terms of teaching orientations and integration orientations. Research results showed that the teacher's deep understandings about 'Global Scientific Literacy (GSL)', the ultimate goal of ESE, precede the sound ESE teaching in the classroom. To enhance teachers' GSL, exemplary aspects of various integration, including networked integration, should be provided specifically to teachers. Also, the institutionalized approaches to developing ESE curriculum could help classroom teachers activate ESE teaching in their classroom.

  • 지구과학은 실생활과 직접적으로 관련되거나 학생들이 친숙하게 생각하는 많은 개념들을 포함하고 있으며 이런 특성은 과학캠프나 자연탐사 활동에서 지구과학과 관련한 탐구주제가 학생들의 큰 호응을 얻는 사실을 설명할 수 있다. 하지만 정규 수업에서 이루어지는 지구과학 실험 수업은 교과서에 제시된 자료해석 위주의 실험이 많아 학생들의 흥미를 반감시키는 경우가 많으며 자료 측정과정에서 과학자가 느낄 수 있는 중요하고 귀중한 경험을 놓칠수 있다. 그런데 인터넷에서는 해양과 대기, 천문, 지질 각 분야에서 지속적으로 갱신되는 실시간 관측 자료를 제공해 주는 곳이 많으며 이 실시간 자료들을 고등학교의 지구과학 실험에 이용할 수 있도록 학습 프로그램을 개발하면 기존의 자료해석 실험이 가지는 한계를 극복하고 학생들의 지구과학에 대한 호응도를 높일 수 있으며 보다 다양한 탐구 능력을 향상 시킬 수 있다. 이러한 학습 프로그램의 특징은 탐구 중심 혹은 문제 해결 학습을 강조하는 현재의 교육 목표를 잘 반영할 수 있다. 본 연구의 목적은 인터넷에서 제공되는 지구과학 관련 실시간 자료들을 활용할 수 있는 고등학교 지구과학 학습 프로그램을 개발하고 이를 지원할 수 있는 홈페이지를 구축한 후 실제로 수업에 적용하여 교육적 효과를 확인하는 것이다. 연구 결과 실시간 자료를 이용하는 고등학교 학생들을 위한 지구과학 학습 프로그램을 12개의 주제에 대해서 완성했다. 먼저 지구과학실험 시간에 적용할 수 있는 2차시 분량의 학습 프로그램 6주제를 개발했는데 개발 주제는 '지진이 일어나고 있는 곳은 어디인가?', '진앙으로 판의 경계를 결정하기', '진앙의 위치를 찾아라', '암영대를 찾아라', '태양의 자전 주기를 측정하기', '태양활동' 이다. 각 주제별로 수업소개, 학습목표, 과정, 학습자료(학생 활동지, 기타 자료, 수업 내용과 관련한 실시간 자료 제공 사이트 목록), 평가 자료를 만들었다. 학생들의 활동 내용은 <지진이 일어나고 있는 곳은 어디인가?>의 주제를 예로 들면 학생들이 실시간으로 전 세계의 지진활동을 모니터하는 사이트에 접속하여 최근에 지진이 어디에서 일어났는지 알아보고 지난 30일 동안에 일어났던 규모 4 이상의 지진 자료를 다운 받아 세계 지도에 점으로 표시한다. 이 때 학생들은 손으로 진앙의 위치를 지도에 그리는 대신 엑셀의 그래프 기능을 이용하여 지도에 진앙의 위치를 나타내게 한다. 또 개인 과제 연구에 적용할 수 있는 학습 프로그램을 5가지 개발하여 학생들이 특정한 주제에 대하여 탐구 과제를 수행할 수 있게 했는데 개발된 주제는 '태양 활동으로 오로라 예측하기', '국제 우주 정거장을 찾아내자', '한반도 부근의 해양 기상과 해수의 물리적 상호 관계', '일기도 분석을 통한 태풍의 진로 예측', '우리 나라 조석 예측' 이다. 마지막으로 사이버 학습을 통해서 수업 시간의 제약 없이 과제 형태로 처치 가능한 학습 프로그램 개발 했는데 그 주제는 '태풍이 저위도에서 북상하는 이유?'이다. 개발된 프로그램 중 2차시 학습 프로그램은 과학고 중학생 영재반에게, 개인 탐구 과제는 과학고 1학년 학생들에게, 사이버 수업 형태는 과학고 2학년 학생에게 적용시켰다. 실시간 자료 활용을 지원하는 홈페이지를 만들어 자료 제공 사이트에 대한 메타 자료를 데이터베이스화했으며 이를 통해 학생들이 원하는 실시간 자료를 검색하여 찾을 수 있고 홈페이지를 방분했을 때 이해하기 어려운 그래프나 각 홈페이지가 제공하는 자료들에 대한 처리 방법을 도움말로 제공받을 수 있게 했다. 실시간 자료들을 이용한 학습은 학생들의 학습 의욕과 탐구 능력을 향상시켰으며 컴퓨터 활용 능력과 외국어 자료 활용 능력을 향상 시키는데도 도움을 주었다.

  • The purpose of this study was to compare what meanings of earth science pre-service teachers and primary pre-service teachers about science books and reading through science disciplinary reading and how their thoughts on science education are reflected in the science disciplinary reading process. For the study, 24 third-year students majoring in earth science education and 25 second-year students majoring in primary education were selected as subjects for the study at a teacher training college located in the central part of Korea. As a result of the study, first, earth science pre-service teachers used disciplinary reading a lot to acquire knowledge of science content, but primary pre-service teachers used it for the purpose of using it in class, scientific interest, and curiosity solution. Second, earth science pre-service teachers and primary pre-service teachers showed differences in their thinking in using science related books for science education. While earth science pre-service teachers rarely described the use of science books in their classes, primary pre-service teachers actively described science classes. Third, from the perspective of science disciplinary reading, primary pre-service teachers were more actively emphasizing the meaning of disciplinary reading compared to earth science pre-service teachers. In light of the research results that the reading activity in science has a lot of effect, it is thought that a wide range of research on science disciplinary reading should be conducted as a teaching strategy in school field classes.
