The purposes of this study were to analyze the contents of sulfuric acid in Science textbooks and Chemistry II textbooks, and to survey 10 pre-service teachers' perceptions who majored chemistry education related to sulfuric acid. As results, most of the Science textbooks represented that sulfuric acid was divided into two $H^+$ and one $SO_4{^{2-}}$. But this mistake might be corrected because sulfuric acid was divided into one $H^+$and one $HSO_4{^-}$. Most of Chemistry II textbooks represented ionization steps of sulfuric acid, but same mistake was represented in some of Chemistry II textbooks. $HSO_4{^-}$ is a weak acid, but some Chemistry II textbooks represented $HSO_4{^-}$ as a strong acid. As results of the survey related to pre-service teachers' perceptions, some pre-service teachers didn't know the situation of particles in sulfuric acid solution, and they were affected on by the learning of high school classrooms.

This study examined pre-service science teachers' perceptions of informal learning by adopting a discourse analysis method suggested by Mortimer and Scott(2003). The guiding research questions were: (1) What are some general patterns of the discourse occurring in science museums between a teacher and a student? (2) In what ways do the pre-service teachers perceive informal learning and teacher's role in informal settings? The 7 pre-service science teachers participated in this study. Each of them shepherd an elementary student around the museum and implemented their own instruction using a pre-planed lesson plan. Results indicated that even though the teachers had learned some characteristics of informal teaming in their college courses, they tended to implement their traditional view of science teaming into the instruction and the view affected them to set up their teaching purposes and contents, and to select communicative approach, patterns of discourse and ways of intervention.

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.

The purpose of this study was to gain a suggestion how to educate pre-service elementary teachers in science education. One hundred and twenty three students were involved in the questionnaire to investigate the perception of science. Many of pre-service elementary teachers had a negative image of science. They consider science to be stiff, inflexible and dull. They suggested much more of foreign scientists than Korean ones as respectable scientists. They are very interested in science related to society, and themselves. It is necessary for elementary pre-service teachers to be educated to positively improve the images of science and scientist, and to understand modern scientific philosophical perspectives. And, Korean scientific history education should be educated formally or informally for them to count on about Korean scientists as respectable ones in science education.

This study is intended to find out pre-service teachers' perceptions of effective teaching behaviors. 89 pre-service teachers observed teaching demonstrations of each other and rated the degree of importance of teaching behaviors and their own performance level. It was found that Class Operations received the highest score in both the importance and performance levels, followed by Lesson Organizations and Verbal Expressions. However, they considered Gesture and Clothing as well as Facial Expressions and Gaze less important. The results of t-tests showed that the differences between the importance and performance levels for all five areas were statistically significant. The results of importance-performance analysis indicated that Verbal Expressions, Eye Contacts, Time Control, and Emphasis on Important Contents are the factors which need to be improved for effective teaching.

The purpose of this study is to explore the possibility of enhancing teachers' pedagogical design capacity using ChatGPT. For this purpose, a survey was conducted to investigate preservice teachers' perceptions of ChatGPT, and lesson plans created using ChatGPT were analyzed from the perspectives of design elements, conversations with ChatGPT, and information transforming. The results showed that pre-service teachers have a rather passive attitude toward the use of ChatGPT, and that teacher moderation and ChatGPT characteristics affect pre-service teachers' perceptions of the use of ChatGPT. In addition, pre-service teachers mainly used ChatGPT for motivational activities and play activities, and there were significant differences in the level of utilization of ChatGPT among individuals, i.e., how they interacted with ChatGPT and how they transformed information. Based on these findings, we explored the possibility of using ChatGPT for teacher professional development and teacher education.
