This study investigated the change of pre-service science teachers' epistemological views of education according to the stages of the field education programs application. For this study, surveys and interviews were carried out threes times before and after participation through participant observation of classes and teaching practices. All data recorded and collected of 28 pre-service science teachers who had answered entire surveys were transcribed and analyzed. The conclusion is as follows; before the participant observation of classes, the pre-service science teachers had views of traditional education affected by epistemology of objectivism. After the participant observation of classes, the views of traditional education increased due to in-service teachers that showed teaching methods through the course of the participant observation. However, it was changed significantly into the views of modern education affected by epistemology of constructivism through the course of the teaching practices. Based on the conclusions of this study, it was identified that the field education programs might have both positive and negative influence on the change of the views of education for the pre-service science teachers. Therefore, Pre-service science teachers should have a opportunity to intensify of constructivism epistemological views of education through the field education programs. The teacher training institutions have to provide systematic and organic cooperation with schools.

The purpose of this study is to investigate earth science pre-service teachers' perceptions and educational utilization of geoparks. It is intended to provide implications of geopark education in the current curriculum and effective geopark education. Education using geoparks has the effect of helping students cultivate inquiry and learning skills, enhancing students' participation in classes. To provide education with these results, it is necessary to deliver meanings of the geopark education to of earth science pre-service teachers who will educate future generations. However, despite the advantages and needs of geopark education, earth science pre-service teachers lack an understanding of geoparks. In this study, 56 pre-service teachers enrolled in earth science education at a university in Gyeongsangbuk-do were investigated for: their perception levels of geoparks, experience, necessity, and learning method of geopark education. As a result, earth science pre-service teachers were well aware of the geoparks, but they lacked knowledge of domestic and global geoparks, confirming the need for geopark education. Currently, the degree of geopark education in the secondary curriculum is insufficient, and earth science pre-service teachers feel the need for it. However, since the understanding of geopark is lacking, support for geopark education is needed. Earth science pre-service teachers being positive about the need for geopark education, it is expected that geopark education will be active in the field of earth science, social, and comparison education when they become teachers in the future.

This study aimed to investigate pre-service science teachers' perceptions of significance and usefulness of evolution and genetics. To this end, 82 pre-service biology teachers and 159 non-biology science teachers answered the items to measure the perceptions of significance and usefulness of evolution and genetics. The validity and reliability were examined using Cronbach alpha, two-dimensional rating scale model Rasch analysis, and factor analysis. The finding illustrated that the test items met the benchmark to be valid and reliable test items. Second, pre-service teachers' perception of significance and usefulness of evolution was independent to that of genetics. The level of pre-service teachers' perception of significance and usefulness of evolution was lower than the level of genetics. Lastly, the levels of pre-service teachers' perceptions of significance and usefulness of evolution and genetics were not significantly different across academic years and majors (biology and non-biology). The findings of this study stressed the importance of teaching significance and usefulness of evolution and genetics in pre-service science teacher education program.
