  • This study aimed to explore the characteristics and dimensions of of systematic functional gestures employed by pre-service Earth science teachers during instructional sessions. Data were collected from eight students enrolled in a university's Department of Earth Science Education. The data included lesson plans, activity sheets, and recordings of one class session from participants. The analysis, conducted using the systemic functional multimodal discourse analysis framework, categorized gestures into scientific and social functional dimensions. Further subdivision identified meta gestures, analytical gestures, and interrelated gestures. Additionally, pre-service teachers used gestures to explain scientific concepts, concretely represent ideas and facilitate communication during instruction. This study emphasizes the nonverbal strategies used by pre-service Earth science teachers, highlighting the importance of noverbal communication in teachers' professional development and the need for its integration into education. It also establishes a systematic conceptual framework for understanding gestures in the instructional context.

  • 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.

  • This study is a report of the collaborative action research which has been conducted between a Korean earth science teacher and science education researcher. A two-year long action research effort was made in order to improve the teacher’s earth science classrooms in pursuit of constructivist principles of learning. The process of the action research was described with the aim of increasing the awareness of science teachers and science education researchers regarding action research. Quantitative evidence was presented to indicate the effectiveness of the collaborative action research in creating constructivist learning environments in the classrooms. The process and quantitative evidence from the action research permitted a consideration of implications for future efforts to improve science classrooms.

  • Since the year 2000, emphasis has been placed on a more strict evaluation of national academic societies and their journals, which has caused most societies to endeavour to produce higher quality journals and research. Korean Earth Science Society (KESS) should be such an exemplary model. Thus, the purpose of this study was to isolate characteristics of well-evaluated academic societies and explore the direction KESS should proceed to better its educational agents and strengthen its research contributions. Back in 2002, the Korean Research Foundation graded the journal of KESS as an officially qualified journal. It was bequeathed the first institute to be registered in the category of Earth Science. Furthermore, such classification was accepted as national academic classification and Scientific Citation Index through a public hearing executed by the Korea Institute of Science and Technology Evaluation and Planning in 2003. Currently, the Korean Research Foundation is reviewing a proposal to approve Earth Science as a unique citation index category. This proposal is quite crucial in that such an approval would be followed by increased funding and affect the future status of KESS. More support and interest from all members of KESS are required to establish the identity of Earth Science as an independent academic entity.

  • 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.

  • 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.

  • Some fine specimens of Annulariopsis bunkeiensis were collected from two fossil sites of the Amisan Formation of Nampo Group distributed in the Jogaegol, Boryeng City, Chungnam Province. According to our detailed study from our new material, the leaves of A. bunkeiensis are not mucronate, but emarginate at their apices. Accordingly, we revised the diagnostic characters given by Kimura and Kim (1988) mainly in regard to the leaf apex.

  • The purpose of this study was to investigate research trends of Japanese earth science education published in Chigakukyouiku by the Japan Society of Earth Science Education. A total of 129 articles published in the Journal between 1998 and 2003 were analyzed. The Journal published six issues each year, and each issue contained about four articles that were fewer numbers than Journal of the Korean Earth Science Society's. About Sixty percent of the papers were written by a single author. Analyzing the content of the papers, it was noted that the most articles were geology-related (41.1%) followed by oceanography-related (1.6%) and general science education papers (1.6%). In summary, the characteristics of research trends of Japanese earth science education are as follows: First, the most topics of the papers were related to environmental sciences including earthquake, volcano, and tsunami. This trend seems natural because Japanese schools are situated within the reach of these environmental events. Second, there found many papers that dealt with geological field trip or fossils adjacent to the local community. Third, there were several papers that established a relationship between environmental education and earth science education. Obviously these papers tried to incorporate environmental education into earth science education at the school level. Last but not least, there found an effort to introduce computer into earth science education as an innovative educational method, for example, 'computer and earth science education'.

  • 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.
