  • On top of several peaks of Seoraksan National Park. many extensive blockfields are found. After initial report was made in year 2000, further field work and analysis of satellite image have been made. Blockfields on top of mountain peaks exhibit evidence of chemical weathering including gnammas and grooves. Also, several lichen colonies larger than 80 cm in diameter have been found on the surface of many blocks. High resolution IKONOS image has been used to delineate the boundary of blockfields which are hard to access during the field trip. Blockfields of Mt. Seoraksan lack fine material necessary for age dating and clay mineral analysis because they experienced long period of wash and erosion during the Holocene. The ages of blockfields seem to be pre-Holocene on the basis of size of lichen colony and weathering pits.

  • The scientific culture programs of 13 Government-supported Research Institutes in the field of Science and Technology (GRIST) in Daedeok Innopolis are studied and classified according to the activities and operational types of programs conducted by GRIST over the past three years (2017~19). The total 150 scientific and cultural programs of GRIST were operational with annual average of 11.5 programs per institution. Science festival and field trip, as a scientific culture activity, account for 72%. By means of operational entity, the programs were identified as 68(45.3%) for PPOI(Programs Planned and Operated by Institute) and 82(54.7%) for PCPI(Programs Contributed and Participated by Institute). Also the 87.2% of all participants were elementary, middle, high school, and college students and the program for adult participants was none. From this study, we suggest that open lab type of science festival programs, which organized and operated by each GRIST, to inform ongoing and advanced research for public understand of research (PUR) and science concerts for targeting adult audiences.

  • The purpose of this study was to examine the perceptions of novelty space among pre-service elementary and secondary earth science teachers. We conducted a survey to explore the perceptions of 38 pre-service elementary school teachers at the National University of Education and 31 pre-service secondary earth science teachers at the Department of Earth Science Education at B University. Semi-structured interviews were conducted with 12 participants, including three pre-service elementary teachers and nine pre-service secondary science teachers. In addition to the elements of novelty space, prior knowledge (cognition), prior outdoor learning experience (psychology), familiarity (geography) with outdoor field learning, and social and technical elements were added. When classified based on elementary and secondary levels, there were statistically significant differences in cognitive, psychological, geographic, and social areas for the elements of novelty space. Statistical differences indicated that the experience or capital related to outdoor learning may have resulted from more pre-service secondary earth science teachers than pre-service elementary teachers. In additional interviews, both elementary and secondary pre-service teachers reported that competencies in the technical domain would be emphasized in the future owing to the necessity and the technical development of virtual-reality-based outdoor field learning programs. This study emphasizes the academic significance of novelty space that should be considered to conduct geological field learning for elementary and secondary earth science pre-service teachers while considering the current post-pandemic educational context.

  • While virtual field trips (VFT) are considered as an attractive alternative to traditional field experience, it is unclear how VFT are best used in Earth Science curriculum. In this study, we investigated the effects of flash panorama-based VFT on students' spatial visualization ability and their understanding of volcanic concept in high school Earth Science class. To investigate the effects of instructional treatment, we conducted pre and post-test on participants' spatial visualization ability and their understanding of volcanic concept, and analyzed using analysis of covariance (ANCOVA) and linear regression. Findings are as follows: First, the change in students' spatial visualization ability in experimental group was significantly higher than that of control group, especially in spatial manipulation category. Second, the change in students' understanding of volcanic concept in experimental group was higher than that of control group in most of the categories, but it is statistically not significant. Last, the change in correlation between spatial visualization ability and understanding of volcanic concept in experimental group was remarkably high compared to control group.

  • The purpose of this study was to qualitatively examine the meaning of students' drawings in outdoor classes and modeling-based learning cycles. Ten students were observed in a gifted education center in Seoul. Under the theme of the Hantan River, three outdoor classes and three modeling activities were conducted. Data were collected to document all student activities during field trips and classroom modeling activities using simultaneous video and audio recording and observation notes made by the researcher and students. Please note it is unclear what this citation refers to. If it is the previous sentence it should be placed within that sentence's punctuation. Hatisaru (2020) Ddrawing typess were classified by modifying the representations in a learning context in geological field trips. We used deductive content analysis to describe the drawing characteristics, including students writing. The results suggest that students have symbolic images that consist of geologic concepts, visual images that describe topographical features, and affective images that express students' emotion domains. The characteristics were classified into explanation, generality, elaboration, evidence, coherence, and state-of-mind. The characteristics and drawing types are consecutive in the modeling-based learning cycle and reflect the students' positive attitude and cognitive scientific domain. Drawing is a useful tool for reflecting students' thoughts and opinions in both outdoor class and classroom modeling activities. This study provides implications for emphasizing the importance of drawing activities.

  • This study analysed inquiry process and activities of the inquiry area in the chemistry field of middle school science textbooks by the inquiry elements based on the 7th science curriculum. The purpose of this study is to grasp a degree of reflecting the 7th science curriculum in the 9th grade science textbooks, and to find out educational implications for the various inquiry learning. Overall, for the analysis of inquiry elements, basic inquiry elements except classification were well reflected on the middle school science textbooks in 9th grade. However, for the integrated inquiry elements, interpreting data occupies almost half of them. This phenomenon is shown in the analysis of inquiry process and inquiry activities, as well. Especially, project and field trip introduced in the 7th science curriculum are hardly found in the textbooks. 9th grade is classified as an upper grade in the 7th science curriculum in terms of inquiry level. Integrated inquiry elements and inquiry activity types, however, are not thoroughly reflected in the 9th grade science textbooks. It is desirable that a variety of inquiry learning of 9th grade be implemented by reconstructing inquiry area based on the results of this study. Hence the degree and ratio of utilizing the integrated inquiry elements and inquiry activity types to the inquiry area of science textbook in 9th grade should be studied.

  • The period from 1946 until his retirement from Department of Forest Resources, Seoul National University was a time of research and professional activity on many fronts for Korean Plant Taxonomy. From 1952 to 1984, he travelled south Korea and collected more than 70,000 specimens. Working out of this project, Dr. Lee developed the SNUA herbarium (Herbarium of The Arboretum of Seoul National University) as the best University herbarium in Korea for the modem floristic work. Dr. Lee's first interest rests on his contributions to our understanding of the twig identification in early 1950. Asian deciduous oak taxa have attracted particular focus to him late 1950 and early 1960. Accordingly Dr. Lee has been one of the specialists on systematic study of Asian oak which is a basis of identification in eastern Asia now. Dr. Lee's contributions concerning rare and endangered plants in Korea provide a tremendous information after a Japanese taxonomist, T. Nakai did in early 1920 to late 1930 in Korea. During his fourteen year career from 1970 to 1984, Dr. Lee spent time to investigate flora of many local and National Park sites. Much of his effort was directed to the voucher specimens for which he worked for the Illustrated Flora of Korea and also served as a field collector. These collections at SNUA enabled us to extend our educational outreach from the local to the national flora research. Although Dr. Lee has been and continues to be the soul of SNUA, collection records about his purpose and aim for each trip are not well documented except date and field studied sites. This lesson enables us to tackle the same issue of balancing quantity and quality with well documented specimens now.

  • As a foundational research for formulating a comprehensive operation plan for Ulsan Library, this study has been undertaken to develop directions for the future library services by performing surveys on the users and library staffs. Consequently, first, the users have demonstrated such a high demand for collaborative services, such as make possible variable library services using a single membership ID across the nation. Second, there is a significant difference in the awareness among the two groups in regards to the awareness of promotional methods for the facilitation of the use of public library in Ulsan. That is, while the staffs highly preferred the use of media such as newspaper, magazines, and radios, users demonstrated the converse and, instead, preferred field trip programs. Third, there seemed to be a certain level of agreement by and among the users and staffs in respect of the library's roles such as that of providing diverse education and programs on reading activities, and that of enabling diverse cultural activities such as arts and culture.

  • This study aims to develop STS modules which consider the local concerns of Korean society and their authentic evaluation instruments. Their titles are as follows: 'Health-Aiding Foods, are they necessary?', 'Competition between Alien and Native Species', 'Living Lesson of Lake Shihwa', and 'Problems of food wastes; Would you like to throw them away, if they are money?' All of them deal with issues unique to Korean local situations. Each module consisted of two versions; a student worksheet and a teachers' guide. Students' activities were categorized into six processes such as group activities, investigation, discussion and presentation, experiments, field trip, and multiple intelligence activities. Various assessment tools and abilities for the decision-making in their STS classes were also included. In order to validate these modules, 24 teachers who have been teaching science, biology and environmental science in the secondary schools reviewed these modules and provided feedbacks about their validity and usefulness. We expect that the various rubrics included in each module will provide teachers creative and flexible assessment methods for students' understandings and their decision-making abilities toward the issues.
