Based on the importance of spatial thinking to understand celestial motion, this study aimed to investigate how spatial thinking was treated in astronomy classes. For this study, we analyzed four elementary teachers' science classes about the unit 'solar systems and stars' in 5th grade in terms of spatial thinking. The results showed that sharing perspectives and orientation explicitly between a teacher and students were important for students to understand celestial motion. Providing the earth-based and the space-based viewpoints simultaneously were helpful for students' understanding of celestial motion. Based on these results, this study suggested that clarifying the viewpoint and orientation, showing the earth-based and the space-based viewpoint simultaneously, and reorganizing the relative units of astronomy based on celestial motion and spatial thinking.

This research analyzed elementary teacher's scientific questioning during science teaching. This research studied 4 elementary school teachers in Gyeongnam were observed and the classes were videotaped. all teacher's questioning and student's answering were transcribed. Teacher's questionings were categorized into 2 types such as simple questions and productive questions. The findings of the research were as following. First, in the teaching-learning activities of the science subject, teacher-student conversation was used 202 times on average, and questions asked by the teachers were 72 times on average. The teachers use productive questions more than simple questions. Second, in the type of simple questions, management questions were used the most, and the next were simple confirmation questions and rethink questions in order. Third, productive questions used by the teachers in the class were mostly the attention-focussing questions, but the type of higher level questions such as problem-posing questions, comparing questions, action questions and reasoning questions was rarely adopted.

Genetic determinism of human behaviors is considered as a philosophical perspective that genes in humans determine biological as well as social traits. However, many biologists agree that human traits are determined by interactions between genes and genes, as well as between genes and environments. In this context, genetic determinism still affect ideas of the general public as well as research directions of biologists. According to Cl$\acute{e}$ment's KVP model (Cast$\acute{e}$ra & Cl$\acute{e}$ment, 2012), teachers' conceptions of genetic determinism influence students' concepts of genetics. This study intends to investigate teachers' conceptions on genetic determinism of human behaviors. For this end, a questionnaire adopted from a previous research (Cast$\acute{e}$ra & Cl$\acute{e}$ment, 2012) has been administered to 308 teachers including 151 pre-service and 157 in-service. Factor analysis has been conducted to extract major factors and one-way ANOVA has been employed to find out differences in extracted factors among different groups of teachers. Four factors have been extracted from 14 items of questionnaire, including factor 1, a perspective of genetic determinism of gender differences in intellectual ability, social status, and emotional traits; factor 2, a perspective of genetic determinism of individual differences in intellectual ability; factor 3, a perspective of genetic determinism of individual differences in biological immune function and behavioral trait; and factor 4, a perspective of genetic determinism of ethnic differences. From the results of One-way ANOVA among teacher groups on four factors, first, it has shown a significant difference in factor 1 (F=3.325, p=.006), factor 3 (F=3.320, p=.006) and factor 4 (F=4.325, p=.001) due to their subject matters. In post-hoc comparison there have been no significant difference between biology teachers and other teachers. It has also been found that there was a significant difference between pre-service and in-service teachers in factor 1 (t=-3.938, p=.000) and factor 4 (t=-3.121, p=.002) and in-service teachers are more genetic deterministic than pre-service teachers. Finally, different religions have no influence on teachers' conceptions of genetic determinism of human behaviors.

The purpose of this study is to explore the research trend changes of convergence education since 2011 compared to the convergence education research that has been steadily continuing in science education. The trend in convergence education were investigated by comparing the number of publications, research subjects, research content, and topic linkages with previous studies, and using the network analysis method to check recent research trends. In the field of science education, the number of papers related to convergence education has been published more than 8.0% steadily, and it has been increasing since 2012, then decreasing again from 2015 and gradually increasing again from 2017. The subjects of study were high in elementary school students, while those in middle school, high school, and university students were low. While the number of in-service teachers increased, the number of pre-service teachers decreased, and the literature and public increased somewhat. In study content, effectiveness studies decreased, while development studies increased, and theoretical and perception studies appeared similar. In thematic linkage, the intra-science linkage was 23.9%, and the extra-science linkage was 76.1% and engineering/technology and art were high in extra-science linkage. In network analysis, elementary, science, STEAM, and program words have a high frequency of appearance and appear together with other words to lead the network. The educational implications of the research trend of convergence education will be more emphasized in the field of science education in the future, and in order to take root in the education field, research on secondary students should be more actively studied. In addition, it is necessary to move away from research on STEAM-centered program development and effects, and to increase research to establish the philosophical basis and theoretical of convergence education.

The purpose of this study was to explore changes of elementary science class in student oriented group inquiry activities using a Science Writing Heuristic (SWH) template that enhance scaffolding of inquiry. The changes focused on students' written reports and perceptions of their learning environment as well as discourse patterns. One fourth-grade class of 29 students participated in this study, and a developed work sheet of science writing was utilized to scaffold student's inquiry activities. Four units in the first-semester text book for fourth grade of the-, 2007 Educational Curriculum Revision were chosen for scaffolding inquiry, and sixteen lessons of instruction were all videotaped. For investigating students' written reports, a framework based on the aspects of science inquiry by Millar (2010) was used to evaluate the coherence between student inquiry activities and their claims. Secondly, a regular fourth-grade class was selected as the control group and was compared with the experiment group using the pre- and post-test of the survey on the perception of science class and science. Lastly, students' discourse patterns of the beginning science lesson were compared with those of the closing lesson. We found that the coherence in the last class increased significantly in students' written reports compared to the first one. Findings also indicated that students' perceptions on their learning environment moved toward student-centered. Based on our discourse patterns analysis, the last class was more student-centered from being teacher-centered than the first one.

This study investigated the types of elementary school students' coping strategies for anomalous situations in science classes. Their epistemological beliefs were then analyzed on the basis of types. To do this, the students (N=75) from 2 elementary schools were asked to respond to an open-ended question about their coping strategies on anomalous situations and some of them underwent in-depth interviews. The analyses of the results indicated five types of coping strategies and were identified as follows: Abandoning, asking a teacher for help, trying the experiment again with same methods, trying the experiments again with different methods, and trying the experiment again after actively analyzing the causes. Among these, the major types were 'trying the experiment again with same methods', 'trying the experiments again with different methods', and 'asking a teacher for help'. The five types were grouped again into four categories such as 'transferring facts', 'constructing facts', 'transferring meanings', and 'constructing meanings' on the basis of the epistemological beliefs toward knowledge and the epistemological beliefs toward relation. The results revealed that 'trying the experiment again after actively analyzing the causes' was only included in 'constructing facts' and the others were included in 'transferring facts'. Educational implications of these findings are discussed.

The purpose of this study is to find out the Learning elements in 'Curriculum Reconstruction' of Elementary Pre-service Teachers in Connection with 'The weather and our daily life'. The pre-service teachers who participated in the study formed a research group of 29 students in 2nd grade who are attending the first semester of A university of education and taking courses in 'teaching research 1'. Participants described the learning topics and contents they would like to add to curriculum 'The weather and our daily life'. Each response was analyzed and classified based on scientific terms related to weather or climate. The results of the study were as follows. First, there were three learning topics related to weather, such as water phenomena in the atmosphere, fine dust and yellow dust phenomena, and light or electricity phenomena, and two topics related to climate such as abnormal climate and global warming. Second, interest in the problem of fine dust and yellow dust in the atmosphere was relatively high. Third, the interest in learning in the knowledge area was relatively higher than in the learning in the function or attitude area. Through these research results, it can be confirmed that it is necessary to develop a climate change or climate crisis education program.
