Abstract

This study aims to investigate the geomorphology and geology of Solseom and Jangyeo areas located on the southern coast of Goseong-gun, where the distribution of dinosaur footprints has not been known so far, and to suggest an educational use by evaluating the potential geological educational value. The research results are as follows. The coastal topography of Solseom consists of sea cliffs, wave-cut platforms, gravel beaches, and tidal flats. The coastal topography of Jangyeo, an uninhabited island, consists of sea cliffs and wave-cut platforms. The sedimentary rocks of the research area are mainly composed of conglomerate, sandstone, and shale with developed stratification. In the sedimentary rock strata, dinosaur footprints fossils, ripple marks, mud cracks, faults, and dikes penetrating sedimentary rocks are distributed. The relationship between the geomorphological and geological landscape distributed in the research area and the learning contents of elementary school science, middle school science, and high school earth science I in the current curriculum is as follows. The coastal topography of the study area, such as sea cliffs, wave-cut platforms, gravel beaches, and tidal flats, were formed by erosion and sedimentation on the coast and are related to the learning contents of the "Change of earth's surface” unit of the third grade of elementary school science. Conglomerate, sandstone, shale, strata, stratification, and dinosaur footprints are commonly related to the learning contents of elementary school science, middle school science, and high school earth scienceⅠ. The fault is related to the learning contents of elementary school science and high school earth scienceⅠ. The sedimentary structures, such as graded beddings, ripple marks, mud cracks, geological structures such as joints and columnar joints, and intrusive structures, are related to the learning contents of high school earth scienceⅠ. In this way, various geomorphological and geological landscapes distributed in the research area are judged to have geological educational value in relation to learning contents by school level. In order to educationally utilize the geomorphological and geological landscape of the research area, an outdoor geological learning method according to the three-step outdoor learning model is as follows. In the preparation stage, the teacher introduces the outdoor geological learning place to the students using a map or satellite map. In the outdoor learning stage, students conduct observation and exploration activities at a designated place in the outdoor geological learning sites. Teachers guide students to a designated place to participate in exploration activities. Students engage in activities using pre-prepared inquiry notes, and teachers respond to students' questions if necessary. In the summary stage, after the exploration, students in the classroom present and discuss the organized data by inferring the geological conditions of the past based on the evidence observed and experienced in the outdoor exploration by individual or group. This area is well accessible and safe, and is suitable as an outdoor learning and training place for teachers as well as students for geological learning. In addition, this area is introduced as Solseom natural ecological park in Goseong-gun, attracting many tourists. However, only the walking course is introduced on the installed information board. It is necessary to reset and further update the information board so that general public and students visiting this place can understand the changes and history of the earth and appreciate the natural scenery.
