The purpose of this study was to investigate and analysis the elementary teachers' and students' views about the difficulties in teaching and learning in geology units of elementary school science. For the purpose of this study, semi-structured interviews were conducted individually with seventeen elementary teachers who have serviced more than three years, and with sixteen elementary students located in Cheongju City. The interview questions were developed through Seidman's step to acquire a reliability in the interview data with triangulation, then in-depth interview questions were modified and completed through pre-interview after constructing the trustworthiness of interviewees. In-depth interviews were performed in applying the analytic induction method and the interviews were recorded. From the interviews, we found that elementary teachers' views about the difficulties in teaching geology units; teachers' inner difficulties, the difficulty of lab activities, the problems of rock samples, the problems of curriculum in geology units, the difficulty of the geological feature, the problems of the cramming education, the lack of the opportunity for the speciality, and so on. And the students have the views about the difficulties in learning geology units; the difficulty of the unit contents understanding, the problems of learning by heart, the lack of the interest, the lack of materials, the problems of rock samples, the difficulty of the field learning, and so on. Based on the results, the study suggested that an interesting lab activities should be included in the geology units and taught in the geological field trip to help elementary school students more fully comprehend contents of the geology units.

This study aimed to explore the geo-educational value of Deokmyeong-ri in Goseong-gun, Gyeongsangnamdo, through field research. The study area comprises well-exposed outcrops, which can be used as field sites during field trip for studying sedimentary structures (normal grading bedding, cross bedding, ripple, and desiccation crack), coastal depositional environments (coastal cliff, shore platform, and gravel beach), basic principles of relative dating (unconformity, fault, intrusion, and xenolith), and columnar joints. This study evaluated the field sites based on the achievement standards and textbooks used in the science curriculum. The field sites have a high educational value because they exhibit typicality, as mentioned in the textbook, and provide study materials for enrichment learning. Furthermore, Deokmyeong-ri Area has well-developed tourist and educational infrastructures; thus, it is a safe place for geological education.

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.

The purpose of this study is to draw an educational implication by analyzing the context of narrative texts, students' narrative thinking, and their academic achievement. We investigated text types in students' geological field trip reports, the reason why students favors narrative texts, the relationship between narrative texts and their scientific knowledge recall, and the relationship between narrative thought and academic achievement. All students used expository texts, 82% of them expressed argumentative texts, and 36% of them used narrative texts. It is likely that students use more narrative texts because students were in the context of outdoor activity and so, their emotional feelings were more activated than when they are doing lab activities. The academic characteristics of earth science seemed to contribute more narrative texts in students' reports. The post-test revealed that students with narrative texts recalled better than the others. On the other hand, there were no statistically meaningful differences in academic achievement between the two groups. However, we have noted that female students whose reports contain narrative texts achieved significantly higher scores than female students whose reports are without narrative texts. From in-depth interviews, we found that students who properly used both paradigmatic and narrative mode of thought were in a more advantageous position than those who used narrative thought only. It was also found that some narratively thinking students tended to feel uncomfortable with the way of learning or evaluating questions about science. In the future, a complementary approach of narrative and paradigmatic mode of thoughts would be encouraged by understanding students' tendency of thinking.

This study is to search the problems of schoolyard teaching material developed by pre-service earth science teachers and the critical factors affecting material making. The 258 schoolyard teaching materials was collected from 54 pre-service earth science teachers (male: 18, female: 36) major in Earth Science Education in Jeonju, Korea. The schoolyard teaching materials was greatly influenced by making process type of it and the prior knowledge of pre-service earth science teachers. As schoolyard preference exploratory type rely on their prior knowledge to develop the schoolyard teaching materials, they made use of the limited concepts like fault in material making. But the concept preference exploratory type made use of concepts not accessible to majority of pre-service earth science teachers because they selected a concept from the earth science textbook first of all. The pre-service earth science teachers having wrong prior knowledge selected inappropriate resources, as well as fell into the error of concept connecting. The pre-service earth science teachers having right prior knowledge partly considered only shape of resources, but had a disregard for formation process of it in material making. Accordingly, we need to reflect richly Geological Field Trip and Solid Earth Science to curriculum for earth science teacher education. And we have to educate pre-service earth science teachers to create holistic concept on the geological subject matter knowledge, field based teaching and learning strategy, material making process.
