한국지구과학회 창립 50주년을 맞아 1979년 창간 한 이후 36년간 지구과학과 지구과학교육 전문가들의 학술교류와 다음 세대 교육에 큰 역할을 한 한국지구과학회지에 출판된 논문을 정량적으로 분석하였다. 한국지구과학회지를 통하여 2014년 8월 기준 35권 1,544편의 논문이 실렸고, 년 간 실리는 논문 수도 증가하여 왔다. 한국지구과학회지에 실린 논문들은 지구과학 내용학 관련 논문이 69.3%, 지구과학 교육학 논문이 30.7%이며, 내용학 논문 중 지질학 55.2%, 대기과학 17.6%, 환경과학 16.0%, 해양학 6.0%, 천문학 5.2%의 분포를 보였다. 최근 들어 대기과학과 환경과학 논문 수가 크게 증가하고 있으나, 지구과학 교육학 관련 논문수는 15년 전 수준으로 감소하였다. 이는 2008년 12월 창간호를 낸 대한지구과학교육학회지의 창간과 관련이 있는 것으로 보인다. 한국지구과학회지에 게재된 외국인 저자들의 공동 참여 논문 수는 53편으로 전체 논문의 3.4%에 불과하여 한국지구과학회지가 우수등재학술지로 정착하기 위해서는 학회지의 양적인 팽창 뿐만 아니라 질적인 성장에도 관심을 기울여야 할 것으로 생각되며, 영문 홈페이지 개선과 함께 국제적 홍보가 필요하다고 생각된다. 교육부는 앞으로 학술지 등재제도의 지나친 문제점의 발생으로 학술지 등재제도 폐지를 통한 학계 자율평가체제로의 전환을 구상 중이며 한국지구과학회지도 이러한 미래의 변화에 대해 철저히 준비하여 학회의 위상을 제고하여야 할 것으로 생각된다.

During the last three decades, earth science has been re-conceptualized as an interdisciplinary discipline entitled Earth System Science (ESS), which is based on knowledge of the physical earth system and human impact on the earth. While there is increasing effort to teach earth as a system in K-12 education, teachers' preparedness of to teach earth system is still in its infancy. This article focuses on reviewing the literature of teachers' knowledge of earth systems and of how teachers' knowledge of subject matter affects their teaching practice and pedagogical content knowledge (PCK). First, the study investigated a literature of PCK in general as well as in science teaching. Then this study duscuss what teachers' subject matter knowledge (SMK) is and what it means to be in teaching earth system science. Third, a literature of teachers' knowledge of earth system was reviewed. Finally, a number of suggestions and implications are made as to what teacher education program should do to better prepare future teachers to teach earth systems.

This study identified and examined earth science education department programs in Korea. Major courses provided by 11 universities and their course requirements were analyzed, and the main research results are as follows. First, many basic courses, other major requisite, and elective courses are provided in geology, astronomy, and atmospheric science. oceanography, geophysics, earth environmental science, and natural disaster and energy resources had fewer major requisite courses provided in addition to basic courses, and few elective courses were offered. Second, many courses in science education focused on earth science, while others focused on general science and there were few courses that covered education theory regarding the specific subject. Third, science course application requirements emphasized the understanding of science in general or of earth science specifically. From the above results, additional studies are proposed to reflect on the current state and supplement these programs.

Three species of Pseudolarix including P. japonica, P. sp. A, and P. sp. B, all belonging to Pinaceae, are systematically described from the Middle Miocene Duho Formation of the Yeonil Group based on the detached seminiferous scales. The presence of Pseudolarix in the Yeonil flora indicates that various kinds of Pinaceae did flourish during the Middle Miocene. The occurrence of Pseudolarix is the first record in the Korean Tertiary flora.

Cupressinocladus sp. found from the upper part of the Jinju Formation of the Shindong Group, Korea is described here based on the newly found leafy shoots. This species is characterized by the branched leafy shoot with decussate scale leaves. The presence of Cupressinocladus in the Jinju Formation indicates that the Early Cretaceous flora-sites in Eastern Eurasia are in a close association with territories of the mixed-type floras. The finding of this species records the first report for the Nakdong flora.

Since 1984, the author has been studying the Daedong flora and has collected a large number of fossil plants from the Amisan Formation of Nampo Group distributed in Chungnam Coal-Field. One of the fossil plants was bennettitalean male flower, which was collected in 1986. The author described it as Weltrichia sp. The occurrence of Weltrichia sp. is the first record in the Early Mesozoic Daedong flora of Korea.

The purpose of this study is to analyze students' learning characteristics regarding spatial ability, orienteering ability and earth science content learning ability and their relationship through development and application of earth science activities using orienteering. The programme aims to improve students' spatial ability using orienteering activity which requires spatial ability. Topics in the programme included map, compass, contour, movement of celestial, and constellation application. Students were to orienteer in the field using the method they learned in class. This programme was applied to five 7th graders. The results are, first, students who have positive attitude toward science and do well at school tended to perceive their orienteering ability high. Second, all parts of spatial ability, spatial visualization, spatial orientation, spatial relation were used during orienteering, especially spatial visualization and spatial orientation. The relationship between spatial ability, orienteering ability, and earth science content learning abilities was not clear. However, orienteering ability and earth science content learning ability were in similar tendency.

This paper presents an analytical framework of Conceptual Understandings of Earth Systems (CUES) that shows a relationship between disciplinary knowledge of Earth systems and the specific thinking skills required to understand that knowledge. This framework is developed through an extensive literature review of students' and teachers' understandings of earth systems concepts and systems thinking in earth science context. This study first presents the categories of disciplinary knowledge of Earth systems, Earth System Knowledge (ESK). This study then illustrates a relationship between categories of ESK and the ontological categories (Matter, Process, Systems) that has been used to study students' conceptual understandings of Earth systems. Finally, this study presents the CUES framework to show the relationship between disciplinary knowledge and thinking skills. The implications of using this framework for curriculum development, assessment, and teacher education and ESS research are discussed.

Nine species of fossil plants were described based on the new material collected from the Hasandong Formation. They are as follows: Thallites yabei, Onychiopsis elongata, Cladophlebis denticulata, C. shinshuensis, C. (Eboracia ?) lobifolia, C. (Klukia ?) koraiensis, Brachyphyllum japonicum, Elatocladus tennerima, and Taeniopteris ? sp. cf. T. auriculata. The floristic composition of the Hasandong flora is very similar to that of the Nakdong flora. This means that both floras might have flourished under subtropical warm arid climate. This flora contains both the Tetori-type and Ryoseki-type floras. It is considered that the Hasandong flora is a member of the Mixed-type floras that existed in eastern Eurasia during the Late Jurassic to Early Cretaceous time.
