The purpose of this study is to explore how the practical knowledge used by an elementary school science teacher during learner-centered science instruction can promote elementary students' construction of positive emotion. Using an auto-ethnographic approach over a period of three months, the researchers collected students' interest diaries, post interviews with students, video recordings in science classes, and students' personal diaries and analyzed them by means of the constant comparative method. In this way, the researchers categorized the structure of the practical knowledge held by the teacher and explained how it was applied in learner-centered science instruction to promote students' construction of positive emotion. Three images of an elementary science teacher's practical knowledge emerged and can be categorized under the following headings: 1) 'From science classroom to science $caf{\acute{e}}$', 2) 'Pleasant experiment class for all students and the teacher', and 3) 'A science class for students who were marginalized'. These images were backed up by principles and rules, and the teacher came to embody these images as he implemented these rules. This study also discusses how the impact of a science teacher's practical knowledge on students' construction of positive emotions can be interpreted as promoting positive outcomes rather than negative sanctions, meeting students' expectation from lab activities, and meeting the specific needs of marginalized students in a science class.

The purpose of this study was to investigate beginning elementary teachers' characteristics and improvement of their teaching skills in science class. The methodology of this study was a qualitative approach that included interviews, classroom observations, and teaching materials. In urban area, low beginning elementary teacher were selected. Four beginning elementary teachers were observed and recorded with VCR in their classroom at seven-times. The results showed that the beginning elementary teachers did not improve in their teaching skills in science teaching, and their characteristics of teaching skills in science were summarized as following; 1) their teaching methods were not inquiry-based science teaching, but explaining-based science teaching, 2) their main aims of the science teaching were focused on the science knowledges, 3) there were little students' science processes involved in their classes, 4) they focused on using textbook as teaching materials, 5) there were little waiting times after their questioning, and they usually used closed-questions rather than open-ended questions.

This study explores the features of sociocultural context of experiment classes taught by a science subject teacher. Two experiment classes on electric circuit for fifth graders were observed and video recorded. The data was also collected through student interviews and teacher interviews. Using the cultural historical activity theory, we extracted the six sociocultural factors and analyzed their interactions. This study could identify that four features of the sociocultural context of the cases. First, the rules of science classes were not decided by the teacher, but formed and modified through the negotiation between the teacher and students or between the students. Second, elementary students played a game, i.e. 'Countdown game', during their electricity experiments, which had both positive and negative influences on science learning. Third, the science teacher feels a limit on life guidance because of the position as a subject teacher in an elementary school. Lastly, although the science teacher had enough time to prepare science classes, there was no guarantee of the improvement of teaching quality. Based on the results of this study, educational implications are discussed in terms of teaching science experiments and of the science subject teacher system.

The purpose of this study was to investigate elementary student teachers' conceptions about the mechanism of the greenhouse effect, the greenhouse gases, the global warming, and their learning experiences of the greenhouse effect and the global warming. Participants were 82 student teachers in their second year of studies (science education: n=28, not science education: n=27) and in their fourth year of studies (science education: n=27). The open-ended questionnaire was used to examine the teachers' spontaneous ideas depicted by their drawings and/or writings. The results of this study are as follows: First, the student teachers' scientific response rate about key concepts related to the mechanism of the greenhouse effect was low (6.1%~28.0%); Second, although there are various greenhouse gases, it was only carbon dioxide that the student teacher's response rate was more than 80%; Third, only 17.1% of the student teachers clearly distinguished the greenhouse effect and the global warming; Fourth, there was a tendency that the student teacher group in the fourth year of studies and science education showed higher scientific response rate about the concepts than the other two groups.

The purposes of this research are to analyze preservice elementary teachers' degree of difficulty in classes of seasonal variation and suggest the measures of classes so that preservice elementary teachers can progress classes of seasonal variation effectively. To achieve them, the research was conducted for 90 first graders completing teaching method of elementary science in P university of education from Sep. to Dec. 2012. This research was conducted, based on the results of in-depth interview for 9 preservice elementary teachers who performed classes of seasonal variation, survey on the degree of class difficulty and evaluation of classes on 8 classes theme of Earth sector in elementary science. The results of this research are as follows. The first, preservice elementary teachers had relatively high class difficulty for teaching seasonal variation among the sector of the earth in elementary science. The second, in the evaluation of preservice elementary teachers' classes, the more the subject showed high class difficulty, the more the score of class evaluation was low. The reason is analyzed that high class difficulty reduces teacher's confidence. The third, preservice elementary teachers had insufficient knowledges and concepts which are basically necessary for the classes of seasonal variation. Especially, it was more serious for preservice elementary teachers who didn't learn Earth-science during their high school time. The fourth, it is necessery that concrete and systematical teaching method should be developed so as to improving preservice elementary teachers' teaching method for the classes of seasonal variation.

This study surveyed the elementary school teachers' use of visual representations and their perceptions of the functions of visual representations in the teaching of electricity unit. A total of 110 elementary teachers who have experiences in teaching electricity unit responded to online survey. The result showed firstly that most of the teachers use visual representations in their teaching and it is mostly limited to those presented in textbooks or images that they can get easily from internet search. Secondly, elementary teachers thought that they have high ability in using visual representations and low ability in understanding students' visual presentation ability. Thirdly, visual representations are more often preferred to be used as teacher-centered ways than student-centered ways for motivating students and conceptual understanding. However, in case of scientific inquiry, both teacher-centered and student-centered ways were equally preferred. Lastly, the teachers' perceptions of the functions of visual representations were categorized into 'teaching-instrumental function', 'learning-instrumental function', 'communicative-instrumental function' and 8 subcategories were found. The most frequent function was the 'information delivery function' in the 'teaching-instrumental function' category. Implications for teacher education and further studies were discussed.
