This study aims to investigate the effects of pre-service elementary teachers' scientific self-efficacy by science motivation according to the academic track in high school. The subjects of this study were 525 pre-service elementary teachers of which 350 pre-service elementary teachers were selected from the humanities and social sciences track in high school and 175 pre-service elementary teachers were selected from the science-engineering track in high school. In order to investigate the difference between scientific self-efficacy and science motivation among pre-service elementary teachers, Independent sample t-test and Cohen's d were done. In order to find out about the Influencing of scientific self-efficacy on science motivation, multiple regression analysis was used. The results of this study were as follows: First, there were statistically significant differences in scientific self-efficacy and science motivation, and the average of pre-service elementary teachers who selected science-engineering were significantly higher. Second, explanation power of scientific self-efficacy on science motivation appeared as 66.7~68.3%. The explanatory power of pre-service elementary teachers' who selected humanities and social sciences were higher. The relative importance was high in task difficulty preference factor to humanities and social sciences, was high in self-regulation efficacy to science-engineering. In conclusion, in order for pre-service elementary teachers to achieve high achievement and motivation in science subjects, and to teach science well to students in the school field, teacher education that can improve scientific self-efficacy should be conducted.

The purpose of this study is to consider pre-service and in-service elementary school teachers' beliefs about STS (Science-Technology-Society), by investigating their opinions on STS interactions. 222 of the seniors in Jinju National University of Education, namely pre-service elementary school teachers, and 185 of the active teachers in Kyung-Nam Province were selected as the objects for researching these matters. Their beliefs about STS interactions were examined. The results were analyzed with a percentage as an examining tool of TBA-STS(Teachers' Beliefs about Science-Technology-Society). The results were as follows; First, on the nature of science, most of them showed simple opinions. On the nature of technology, most of them also showed simple opinions. most of them recognized the interactions among science, technology, and society affirmatively. They showed simple opinions on the interactions between science and technology. In fact, they didn't recognize the interactions between science and society, but they knew the influence of technology on society relatively concretely. Second, if one consider the cognitive situation or the distributing route of STS, he can easily find that most teachers never or little know it. At present, pre-service teachers learn STS from the lectures in their universities, and in-service teachers get information about it from science magazines/newspapers and training.

The purpose of this study was to investigate the astronomy-related concepts formed by elementary school pre-service teachers and analyze the distribution of misconceptions. The study was conducted on 43 pre-service teachers enrolled in the second year of an elementary teacher training college located in the central region of Korea. As a result of the study, first, pre-service elementary school teachers' misconceptions about astronomy concepts showed a diverse distribution. In particular, pre-service elementary school teachers still had misconceptions regarding seasonal changes, which were pointed out in many previous studies. Second, pre-service elementary school teachers had formed concepts at the level of simple memorization of astronomy concepts and were having difficulty applying the concepts they knew to various cases. Based on these research results, future astronomy-related education should be directed toward understanding astronomical phenomena through the application and application of various cases rather than simple memorization, and astronomy education in teacher training courses and teacher training should also reflect this content.

The purpose of the study is to enhance the teaching competence for pre-service elementary teacher by using DGE in order to enhance SMK and PCK for them. To do this, we investigated the initial SMK and PCK for 23 pre-service elementary teachers, the reality of implementation activity of DGE and the change of SMK and PCK after quest activity by DGE. As results, 3 pre-service elementary teachers made errors which are misunderstanding a general angle as special angle, an excessive jump of logic and a circulation logic in the aspect of an initial SMK. In the aspect of contents of PCK, most of pre-service elementary teachers proposed teaching focused on the character using in the problem solving. And most of pre-service elementary teachers proposed teaching methods which are based on explanation, measurement and material manipulation. The reality of implementation activity of DGE was classified 4 cases which are a difficulty in understanding the concept of dynamics and embodying in DGE, an obsession about construction of $75^{\circ}$ and generalization, a difficulty in interpreting 'folding activity' mathematically and a good implementation activity. After quest activity by DGE, the case which is misunderstanding a general angle as special angle could be improved, but the others are not. And after quest activity by DGE, most of pre-service elementary teachers still proposed teaching focused on the character using in the problem solving in the aspect of contents of PCK, and some of pre-service elementary teachers added only teaching methods which are involving visual confirmation by GSP. From these results, we could extract some pedagogical implications helping pre-service teachers to reinforce SMK and PCK by DGE.

The purpose of this study was to explore strategies used by pre-service elementary science teachers in planning a science lesson. The participants were six senior students from a national university of education located in the midwestern area of Korea. Data regarding their planning strategies were gathered through both thinking-aloud and observation. Research findings suggest that: three of the teachers had little understanding of the necessity of reviewing unit contents or prior learning for planning a science lesson; five student teachers relied heavily on learning objectives presented in teachers' guidebooks without considering their appropriateness; all teachers exhibited an intention of composing different activities or teaching approaches from teachers' guidebooks; only two teachers thought about learners' prior knowledge or understanding levels; five and three teachers had poor understanding of discovery learning models and importance of teacher's questioning, respectively; and five teachers paid little attention to assessment.

The purpose of the research was to analyze the characteristics which appeared to the process of designing experiment for pre-service elementary teachers. This study were participated 26 pre-service elementary teachers. The findings indicated that first, the researcher figured out the process elements could constructed in 12 elements such as 'states problem or question, predicts outcome or hypothesizes, lists materials needed, arranges steps in sequential order, lists more than 3 steps, Explore variables and select one or more variables, plans to control variables, plans to measure and observation, plans data collection, plans to repeat testing and tells reason, states plan for interpreting data, states plan for making conclusion based on data, states plan for making conclusion based on data' but did not figure out 2 elements such as 'defines the terms of the experiment, practice safety'. second, the characteristics of pre-service elementary teachers in the process of designing experiment were as follows; pre-service elementary teachers designed experiments unstructured process listed types and showed the superficial level of the design experiment. The results show that the programs of designing experiment activity should be constructed with the process elements which were concentrated by pre-service elementary teachers, should provide feedbacks to design experiment more accurately.

Through the criticism and evaluation of different classes teaching the same lesson topic, this study compared the viewpoints by two ways between two groups including pre-service and experienced teachers. Through free-style criticism, this study analyzed the differences between pre-service and experienced teachers' areas of attention. Through criteria-based analysis, the study analyzed the judgement of each area and the criteria of each judgement. The results of the study found that pre-service teachers criticised more limited areas, but somewhat more positive than their experienced teacher counterparts. Also, pre-service teachers did not observe thoroughly whether or not the teacher was well-informed of the science content, the sequence of curriculum, and whether or not meaningful interaction had occurred. As well as, pre-service teachers were not actually feel importance of student-oriented lessons, and they could not look room and materials are useful to students on students' sides. Additionally, pre-service teachers thought highly of lessons which were connected to other subjects rather than connected to daily life. Therefore, to notice diverse areas in the class, pre-service teachers need to criticise lessons using a diverse criterion. Also, pre-service teachers realized simple questions and that mechanical group activities are not always effective and that they need to think how to improve meaningful interaction. Moreover, they have to perceive that an inquiry-oriented student-lead approach is very important. Lastly, pre-service teachers have to closely consider the room efficiency and materials available to the students, and they must internalize that science class has to be connected with daily life.

This study used questionnaires to investigate how pre-service elementary teachers understand ocean acidification. As a result of gender, female teachers were more aware of ocean acidification than male teachers, but male teachers had a higher average rate of correct answers, with a lower standard deviation. Teachers from the natural sciences knew more about ocean acidification than did teachers the liberal arts. Teachers ranked environmental crisis in order of most dangerous to least dangerous as follow: global warming and the greenhouse effect, ozone depletion, ocean acidification, and acid rain. About 46.7% of teachers learn about ocean acidification through education, followed by broadcasts, school lectures and the internet. The educational materials most desired for teachers were videos related to ocean acidification. Pre-service elementary teachers have two broad perspectives on ocean acidification. Firstly, they refer to economic loss and food shortages, and secondly, they note that there is a need for improved awareness and publicity about ocean acidification. The role of elementary school teachers is important because their awareness of environmental issues has a considerable effect on teachers perception of the environment. Revitalizing education on ocean acidification and government support are necessary to effectively communicate the seriousness of ocean acidification. Lastly, we need to study ocean acidification in detail so as to be able to persevere toward protecting our ocean ecosystem.

The purpose of this study is to examine how elementary pre-service teachers have a perception of 'science'. Especially, this study used photo-narrative method to analysis pre-service teachers' perception of 'science'. Photo-narrative is a way of describing what a study participant wants to say by taking a picture. Participants were 66 elementary pre-service teachers. The results of this study were as follows: First, elementary pre-service teachers used many words such as people, life, everyday as well as scientific terms such as phenomena and principles to explain science. Secondly, the pictures used by elementary pre-service teachers to explain science included household goods, natural phenomena, advanced devices, and living things. Third, elementary pre-service teachers explained science with knowledge of science, knowledge, convenience, and nature of science. As a result of this study, it was found that elementary pre-service teachers recognized that science is closely related to life and that it is necessary for learning. The results of this study can contribute not only to curriculum composition and curriculum content of elementary and middle school science education but also to curriculum development for teacher training.
