Abstract

Faulting is one of the various pieces of evidence for crustal movement. The rock masses on both sides of the fracture in the crust and is caused by crustal movement move relatively. This fracture is called a fault. Faults can occur on all rocks. Faults in massive rocks such as igneous and metamorphic rocks may be difficult to recognize. However, faults in sedimentary rocks with developed stratification are relatively easy to find. In addition, the degree of movement of the rock mass in the fault can be observed. The fault, one of the geological structures created by a tectonic process such as crustal movement, is a very interesting structure for students to understand the history of the Earth. The fault is presented as learning content in the 2015 curriculum, elementary school science, and high school earth science 1 subjects. In textbooks, photographs and illustrations about faults are presented as learning materials instead of real faults or models. In textbooks, it is necessary to consider presenting fault photos to help students observe quantitatively. This study introduces the faults of various characteristics distributed on islands in Yeosu-city, Jeollanam-do as localized data and proposes a reorganization plan to present fault photos for geo-educational use. The results of this study can be used as basic data for the revision of the next curriculum as well as localization learning materials for the fault centered on Yeosu-city, Jeollanam-do. The research results are as follows. The size of a total of seven fault photos analyzing science and earth science 1 textbooks varied from 5cm to 18cm in width and 4cm to 9.5cm in length. Out of a total of 7 fault photos, the distribution indicators of the fault were three in Korea and one in foreign countries. There was an example of a geological hammer being used as a scale in one of a total of seven fault photos. Two places on Myodo, one on Odongdo, two on Sado, two on Nangdo, and one on Jeokgeumdo of Yeosu-city were surveyed, and a total of eight photos were taken of the faults distributed in these areas were presented as localized learning materials. As a way to reconstruct fault photos, an enlarged or close photograph of the fault part along with the stratified strata should be presented. In addition, in order for students to quantitatively observe the thickness of the stratum or the displacement of the stratum in the fault photo, a scale or ruler must be displayed together on the fault photo.
