The purpose of this study is to identify the conceptions of elementary school teachers regarding the variation scale about astronomical distance and its accuracy with distance increased. The astronomical distance questionnaire was administered to 69 elementary school teachers, then; three teachers were selected to interview about their conceptions. Results showed that many elementary school teachers overestimated the distance from the Earth to the Moon and to the Sun, and dramatically underestimated the distances to the nearest star and to the nearest galaxy. They inferred astronomical distance with the use of both intuitive (psychological) measure and theoretical (calculative) measure. They well recited the terminology such as AU and a light-year, yet they did not show a good understanding of what the terms exactly means. Some teachers thought that the distance to Neptune is farther than the distance from Earth to the nearest star. There was a considerable variability in the participants' estimates of astronomical distances. Elementary school teachers showed a tendency to overestimate the distance as it gradually increases to the outer solar system.

In this study, data were collected from currently employed early childhood teachers in order to explore the factors affecting the teacher efficacy of early childhood teachers and 202 data were analyzed. Frequency analysis, correlation analysis, and multiple regression analysis were performed on the subjects' general characteristics, empathy, resilience, and teacher efficacy. As a result of the study, factors influencing early childhood teachers' teacher efficacy were identified as educational experience, job achievement, empathy, and resilience, and the explanatory power of the variable was 57.2% (F=45.848, p<.001). In conclusion, the higher the resilience (β=.480), job achievement (β=.286), teaching experience (β=.197), and empathy (β=.141) of early childhood teachers the higher the teacher efficacy was. Therefore, the development and education of a curriculum that combines regular and non-regular education programs that can improve resilience, job achievement, and empathy from the period as pre-service teachers are required to improve teacher efficacy of early childhood teachers.

Frequently, pre-service elementary teachers are asked to write reflective journals on their teaching during teacher education program. However, writing reflective journals can not guarantee pre-service teachers to learn from their experience. In this study, 44 reflective journals of pre-service elementary teachers on their science teaching were analyzed in terms of 'productive reflection', a concept suggested by Davis (2006). Productive reflection may help teachers' effective learning by considering interrelationships among aspects of teaching including learners and learning, subject matter knowledge, assessment, and instruction. The result showed what aspects of teaching were included, emphasized, and integrated in the pre-service elementary teachers' reflective journals. Implications for teacher education would be discussed.

This study is a basic research to apply ESD linked to SDGs to pre-service teachers majoring in earth science education. The purpose of this study is to evaluate carbon literacy by analyzing the awareness, attitude and knowledge, subjective norms, and behavioral control of the carbon footprint internalized by pre-service teachers. Pre-service teachers recognize the carbon footprint as their responsibility, but are not willing to pay the cost and accept inconveniences of the actions to reduce carbon footprint. They also support actions to reduce carbon footprint, but do not demand the actions from others. While they have sufficient knowledge about carbon mitigation actions, their conception of causes and effects of global warming is unstable. Pre-service teachers will go out to school sites and teach millions of students about global warming. It is essential to educate these teachers on the economic cost and social responsibility of reducing their carbon footprints. It is also important to find ways to bridge the gap between their thought and action. It is hoped that this study on pre-service teachers' carbon literacy will lead to realizing ESD.

The purpose of this study is to analyze the perception of integrated school education and education for sustainable development of secondary school science teachers, judging that the existence of a common science teacher qualification certificate is related to the expertise of the common science map. To that end, the survey was conducted for three months from June to August 2018 for secondary school science teachers, and multiple choice questions were analyzed as statistical processing and descriptive questions as topical modeling. According to the analysis, teachers with a common science teacher qualification certificate had a high awareness of integrated school education, and the response average was high in all areas of value, direction and success condition of integrated school education. In addition, the average response of teachers with a common science teacher qualification certificate was also found to be higher than those with a common science teacher qualification. There were no major differences in perception between the two groups on the strength of science education and ESD integration, but the difference was that teachers with a common science teaching certificate focused on science in all topics and recognized science as a medium for each topic compared to teachers who did not.

This study aims at investigating the perceptions of science teachers about the role of visual representations in the teaching of electromagnetism, and finding out how science teachers use visual representations in their teaching of electromagnetism and the difficulties they experience in dealing with those representations. A total of 121 science teachers responded to the online survey. The results showed that most of the teachers agreed to the significance of using visual representations in the classroom but regarded their role as means of simply delivering science knowledge rather than constructing or generating knowledge. For the three visual representations widely used in teaching of electromagnetism in secondary schools (electrostatic induction on electroscope, magnetic field around current carrying wire, structure and principle of electric motor), the teachers preferred teacher-centered use of visual representations rather than student-centered and teacher's construction of representations were the most frequent among four types of use; interpretation, construction, application, and evaluation. The difficulties of teaching with these three visual representations were categorized into several factors; teachers, students, the characteristics of the representations, and lack of resources and classroom environment. Teachers' limited perceptions about the role of visual representations were associated with the ways of using visual representations in their teaching. Implications for the effective use of visual representations for science learning and teaching were discussed.

This study investigated the common features of the best practices in the science classroom, which is the core of school education. The underlying assumption of this research is that the fulfillment of school education is possible with substantial instruction of school curricular areas. The substantial learning of any curricular area depends on each classroom lesson. Data from classroom observations in-depth interviews with teachers and a group of students, a collection of instructional materials were used to extract common characteristics of best practices implemented by 10 exemplary secondary-school science teachers. Common features of best science practices were analyzed in terms of (1)reorganization of science content, (2)pedagogical skills, (3)evaluation, and (4)teachers' efforts for professional development. Results indicated that exemplary science teachers adapted curriculum and textbook content according to students' level and learning context, were able to use a variety of instructional methods and strategies, provided cooperative and intellectually challenging learning environment, and improved their instruction based on assessment results. Also, these exemplary teachers not only improved their own classroom practices, but also participated actively in various professional community of science teachers to share their practical knowledge with their colleagues. They took an active role in teachers' in-service education.

The purpose of this study is to analyze the science lesson plan of pre-service elementary teachers about condensation. Pre-service elementary school teachers in A national university of education was included in this study. Through the analysis of prior research and expert review, a framework for analysis of science lesson plan of pre-service elementary teachers was derived. The results of the using the analysis frame are as follows: First, the ability to apply the instructional model in the science lesson plan about condensation differences in pre-service elementary teachers need to be enhanced due to deviations, and teaching on the exact understanding of condensation-related concepts of pre-service elementary teachers is also needed. Second, there is also a deviation of pre-service elementary teachers in the beginning, development, and finishing composition of lesson course, so feedback should be supplemented. Third, in the sub-domain of lesson environment, there was a demand for specific know-how on the lesson environment. Therefore, support is needed for related PCK growth. Fourth, the sub-domain of lesson evaluation have a variety of perspectives on timing and subjects, and some missing about learning objectives in the composition of evaluation content are found to require complementary teaching. In order to improve this situation, it was found that there was a need to prepare conditions for improving science teaching professionalism of pre-service elementary teachers through in-depth discussions on the teaching methods and organization related to science education in the university of education course.

This study aimed to investigate the current state and educational needs of risk education related to science and technology as perceived by secondary science teachers. A survey was conducted with a total of 366 secondary science teachers. The results are as follows. First, There were more teachers who had not provided education on risks arising from science and technology in terms of risk perception, risk assessment, and risk management than those who had not. Global warming was the most common risk taught by teachers, followed by earthquakes, artificial intelligence, and traffic accidents. Second, teachers recognized that they lacked understanding that the achievement standards of the 2022 revised science curriculum include risks that may occur due to science and technology, but they thought they were prepared to teach. Third, teachers recognized that their understanding of risk perception was higher than that of risk management and risk assessment. Fourth, the experience of teachers in training on risk was very limited, with fewer having training in risk assessment and risk management compared to risk perception. The most common training experienced was in laboratory safety. Fifth, teachers recognized that their capabilities for the 10 goals of risk education were not high. Middle school teachers or teachers majoring in integrated science education evaluated their capabilities relatively highly. Sixth, many teachers thought it was important to address risks in school science education. They prioritized 'information use', 'decision-making skills', and 'influence of mass media', in that order, for importance and called for urgent education in 'action skills', 'information use', and 'influence of risk perception'. Seventh, as a result of deriving the priorities of education needs for each of the 10 goals of risk education, 'action skills', 'influence of risk perception', and 'evaluate risk assessment' were ranked 1st, 2nd, and 3rd, respectively.
