This study included eleven elementary pre-service teachers who participated in the first and second teaching practices held by J Education College in 2015. After the pre-service teachers were encouraged to self-reflect on their mathematics teaching using a reflective survey sheet of mathematics teaching expertise, their uses of mathematics teaching expertise were analyzed according to the times of their mathematics practice instructions. The results are as follows: First, as the frequency of their mathematics teaching increased, the pre-service teachers' uses of mathematics teaching expertise increased, especially greatly with seven of them. However, the number of subcategories where the teachers' uses of mathematics teaching expertise increased was different from at least two to seven depending on the teachers. Second, the pre-service teachers who performed mathematics teaching practices four times used more of mathematics teaching expertise than those who did two times or three times. Third, some pre-service teachers who taught two or three times never reached 90% of the total score of any subcategory, even in the subcategory where they showed increase in their uses of mathematics teaching expertise. Fourth, the subcategory of 'reflection before class - teaching perspective - understanding of mathematics subject knowledge' was analyzed as the most difficult one for the study participants, and the reason is, they think, that there are not enough materials on the historical back grounds of mathematical concepts.

This research aims to examine the characteristics and main subjects of the mathematics class-criticism by elementary' teachers. In this aim, we analyzed the mathematics class-criticism by the 11 elementary teachers. As the results of this research, the elementary teachers criticized the mathematics class while understanding and describing the class as it is. And mathematics class-criticism by elementary teachers showed contextual and situational characteristics. Furthermore, the main subjects of mathematics class-criticism by elementary teachers were identified as mathematical communication, teacher's question to foster the students' mathematical thinking, appropriateness of task, motivation for students, concrete operational activity, appropriateness on teacher's mathematical behavior and teacher's use of mathematical term, experience of inductive reasoning. While, we identified the significance of mathematics class-criticism for elementary teachers. The elementary teachers pointed out the necessity and importance of the mathematics class-criticism on the mathematics class in usual context.

Even though identical science textbooks are used in elementary science classes, differences exist in teachers' teaching practices. The purpose of this study was to understand the relationships between elementary teachers' beliefs of science learning and their science teaching practices. An Likert-scale survey and interviews were performed on four elementary teachers to obtain information about the beliefs of teachers in science learning. In order to understand their teaching practices and the relationships between teachers' beliefs and their teaching practices, 2 classes per each teacher were recorded and instruction analyses were performed in the aspects of teaching contents, methods, and learning environments. The results showed that teacher A and B, who held traditional beliefs of science learning, taught their classes mainly based on teacher's explanation. While, teacher C and D, who held constructive beliefs of science learning, reorganized the contents of textbooks and applied various teaching methods and strategies in conducting their teaching practices. There were differences in teachers' beliefs of science learning and teaching practices. These differences in beliefs were related with their science teaching practices.

This study is a case study of an elementary school teacher's reflection and practice in the process of planning, executing and criticizing his lesson on division with decimals. The purpose of this study was to clarify what kinds of problems an elementary school teacher was thinking about and how his focus was changing in the process of planning and executing a lesson and criticizing his lesson with his peers. The teacher was set in three periods: a teacher planning a lesson, a teacher executing a lesson, and a teacher criticizing his or her own lesson. Each period was analyzed in eight aspects: Establishing the goals for mathematics, implementing tasks, connecting mathematical representations, facilitating mathematical discourse, posing questions, building procedural fluency from conceptual understanding, supporting productive struggles, and using evidences of students' thinking.

This study was to investigate what pre-service teachers pay attention to when designing science lessons. As a result of analyzing the responses of pre-service teachers, it is analyzed that pre-service teachers are designing science lessons with emphasis on science inquiry, considering students' interest, level, and treatment of misconceptions, and closely related to daily life. In particular, it was found that elementary school pre-service teachers made a lot of comments on science class design that emphasizes experimentation and inquiry, so it was found that emphasizing inquiry was recognized as an important point in science lesson design. It is very positive that pre-service teachers recognize important aspects of science education, such as emphasizing inquiry. In addition, it is suggested that the opportunities for class design and demonstration through collaboration with teachers and colleagues should be increased for pre-service teachers' professional development of teachers.

This study investigated the aspects of how three preservice elementary school teachers conducted the data-text transforming discourses in their science simulation teaching and how their epistemological conversations worked for learners' construction of scientific knowledge. Three preservice teachers, who had presented simulation teaching on the seasonal change of constellations, participated in the study. The results revealed that one preservice teacher, who had implemented the transforming discourses of data-to-evidence and model-to-explanation, appeared to facilitate learners' knowledge construction. The other two preservice teachers had difficulty helping learners construct science knowledge due to their lack of transforming discourses. What we should consider for improving preservice elementary school teachers' teaching competencies was discussed based on a detailed comparison of three cases of preservice teachers' data-text transforming.

The purpose of this study was to understand what orientations elementary school teachers have related to their science classes, what realities they encounter in real classes, how they overcome their frustrations and failures they experience. We employed a narrative inquiry method and analyzed the experiences of two early career elementary school teachers (Miss Park and Mr. Choi). Miss Park wanted to conduct students-driven inquiry classes, in which students become active investigators, but in reality, she faced herself who conducted teacher-driven classes. Mr. Choi wanted to conduct science classes based on constructivism, but in reality, he encountered himself as a knowledge giver rather than scaffolder. However, rather than giving up their orientations, the two teachers tried to keep them in their own way. It was expected that by understanding what strategies beginner teachers take when their theoretical orientation and ideals are not well implemented in actual educational reality, we could find a clue that will lead to a more successful transition from pre-service teacher to teacher.

This study investigated the impact of elementary school science classes based on collaborative problem-solving on the character competency of students. For this purpose, students from 2 classes in 5^th grade at an elementary school in a metropolitan city were targeted, and elementary science classes based on collaborative problem-solving were developed and applied to the 5 topics selected from the 'dissolution and solution' unit in the elementary science curriculum. In order to investigate the effect of science class based on collaborative problem-solving on the character competency of students, results of the character competence test before and after the class, reflective writing activity sheets filled out by the students in the experimental group, and questionnaires regarding their changes in character competency after the class were analyzed. The results showed that elementary science classes based on collaborative problem-solving were effective in cultivating the character competence of elementary school students.

This research intends to give a practice of mathematics lesson-critique and some perspectives on a mathematics lesson in the elementary school level. We carried out a mathematics lesson-critique on a lesson chosen as a good lesson by a local educational district in Korea. The main themes of mathematics lesson-critique were the reconstruction of lesson models, the pursuit of relational understanding, the activation of mathematical communication, and the didactical transformation by a in-service teacher. Meanwhile we confirmed that we need to discuss the properness and adequateness of contents about division of natural numbers given in the elementary mathematics textbook and teachers' guide according to the revised 2007 mathematics curriculum.
