In this study, we investigated the relationships among elementary school teachers' perceptions of constructivist science assessment, views on science teaching and learning, science teaching efficacy belief, and the perceptions of constructivist science learning environment. An exploratory factor analysis was conducted to validate the factor structure of the perceptions of constructivist science assessment test. The test consisting of 3 factors with 21 questions in the previous research was reconstructed as one consisting of 2 factors with 22 questions as a result of the factor analysis. A stepwise multiple regression analysis was also conducted to predict the explanatory powers of the variables on perceptions of constructivist science assessment. The results indicated that the perceptions of constructivist science learning environment, views on constructivist science teaching and learning, and personal science teaching efficacy belief were the significant predictors of the perceptions of constructivist science assessment.

Scientific creativity is necessary for all ordinary students in ordinary school settings. In this study, a practical format for teaching scientific creativity is suggested, and sample teaching materials based on this format are developed. To facilitate the practical use of the teaching materials in ordinary schools, the model of IS3CA(Iterative Small Scale Scientific Creative Activity) was proposed. Using this format and the proposed teaching materials, a brief in-service program was developed and implemented. Here, the aim is to improve teachers' actual professional ability to develop their own teaching materials rather than just using the pre-developed teaching materials provided by the researcher. Positive responses about the in-service program were collected from the teachers, and the results also showed that the development of teaching materials by teachers was possible. Therefore, I expect that the teaching of scientific creativity by ordinary teachers is possible for ordinary students in ordinary school contexts. Finally, based on the results and experiences of this study, a curriculum for teaching scientific creativity is suggested.

This study explores the impact of a STEM integration teacher professional development program focusing on teachers' perception of engineering and their attitudes toward integrating engineering into teaching. A total of sixty-eight teachers from ten schools participated in the program for five days. Data are collected from three main sources including (1) pre and post concept maps probing teachers' perceptions about the engineering discipline, (2) a pre and post survey measuring teachers' self-efficacy of teaching science/mathematics within the engineering context, and (3) engineering integrated science and (or) mathematics lesson plans and teaching reflections. This study utilizes both qualitative and quantitative research methods depending on the data we have collected. The results show that both science and math teachers thought that integrating engineering into teaching provided valuable outcomes, i.e., promoting students' learning about engineering and improving their interest in science or math through real-world problem solving exercises. Participants also felt more comfortable about integrating engineering in their teaching after the program. The results also imply that the teachers' understandings of engineering become more concrete after the program. This study also provides an overview of the challenges and advantages of teaching engineering in K-12 science and mathematics classrooms.

This study explored changes of preservice biology teachers' pedagogical knowledge and science teaching efficacy belief after the science pedagogy course. Preservice biology teachers who did not take any science pedagogy courses had an opportunity to engage in discussions of educational theories and group activities of instructional design utilizing science instructional models as a first step to develop practical knowledge. These preservice teachers represented a statistically significant increase in their scores on pedagogical knowledge including theory, student development, planning, and implementation, but no statistical difference in their scores measuring science teaching efficacy belief. In addition, the correlation results indicated that the science teaching efficacy belief is related to implementation even though the magnitude is relatively moderate.

The self-efficacy of pre-service teachers has been reported as a major factor in the instruction of the curriculum. In particular, considering the importance of science learning instruction for underrepresented students from the viewpoint of science education for all, pre-service elementary teachers' self-efficacy about science instruction for underrepresented students will be an important factor of science education for these students. The purpose of this study is to investigate the self-efficacy of pre-service elementary teachers in science instruction for underrepresented students. To this end, the science teaching and learning self-efficacy test tool (Lee & Im, 2010) was revised in accordance with the context of science teaching for underrepresented students into a total of 24 items using 5 Likert scales. Through using the test tool consists of 3 dimensions as Learning Efficacy, Teaching Efficacy and Outcome Expectancy, 81 pre-service elementary teachers were surveyed and the reliability of test tool was verified through factor analysis and assessing construct validity by using the responses. As a result of the analysis, setting 5 as the standard perfect score, the average score of self-efficacy per dimension was shown as 3.29 in Learning Efficacy, 2.89 in Teaching Efficacy, and 3.39 in Outcome Expectancy. We confirmed the tendency and difference of self-efficacy of the research objects according to their background factors in which direct and indirect experience relating to the science education for the underrepresented students. Also, we verified that pre-service elementary teachers' interest in science subject matter, teaching science and their perception of the value of science learning had significant relations with self-efficacy on science teaching for underrepresented students.

This study explore characteristics of teaching orientation and pck of science teachers in online-offline mixed learning environment. Data consisted of open-ended survey, semi-structured interview, class observation, field notes from 12 science teachers. We categorized teaching orientation considering both science education goals and science teaching·learning orientation. There were 8 different teaching orientations such as 'understanding science concepts-lecture centered' 'constructing science concepts-inquiry based' 'applying science concepts and inquiry-inquiry based' 'applying science concepts and inquiry-lectured centered' 'analyzing and judging science information-inquiry based' 'developing scientific attitude-inquiry based' 'developing scientific attitude-lecture centered' and 'developing perception of interrelationships among science, technology, and society-inquiry based'. Teachers with inquiry based teaching·learning orientation seemed to have knowledge of science curriculum specific to online learning environment for student inquiry. While teachers with 'understanding science concepts-lecture centered' teaching orientation appeared to have questioning strategy of checking student understanding and strategy of repeating a lecture, teachers with 'constructing science concepts-inquiry based' teaching orientation appeared to have knowledge of instructional strategies to perform online group activities targeting student construction of knowledge and to replace face-to-face group activities with virtual experiments and individual experiments. While teachers with 'understanding science concepts-lecture centered' teaching orientation did not show knowledge of student science learning, teachers with 'constructing science concepts-inquiry based' teaching orientation appeared to have knowledge of student difficulties in inquiry based learning.
