The purpose of this study was to investigate the process and the effect of pre-service teacher's scaffolding in environmental camp program about global climate change. For this study, developed the environmental camp program based pre-service teacher's scaffolding and applied to 78 $5^{th}$ students. We analyzed the role of pre-service teacher in the process of scaffolding. In the result, the pre-service teachers conducted cognitive scaffolding like as "Focus", "Hint", "Tell or Summarize" and "Technical Help". They carried out the emotional scaffolding like as "Create Cheerful Atmosphere", "Encourage", and "Help in Living". Teaching and learning about global climate change, the theme of the camp, was regarded uncertain and complex. So, pre-service teacher's scaffolding was effective to promote environmental literacy about climate change of primary students (<0.05). The student teachers understanded the characteristics of the children through emotionally close relationships. The primary students were learned easier about global climate change through cognitive and emotional scaffolding. They experienced environmental practice with communal living in camp.

In this study, we analyzed the change of teacher knowledge through task design in the teacher-researcher community focused on knowledge of students in the area of derivatives application. The following subjects were studied. First, we have analyzed the focus of the discussion related to teacher knowledge of students within the teacher-researcher community. Second, we have analyzed the change of teacher knowledge of students according to the focus. The results of this study are as follows. First, community member' different knowledge of students led the discussion on the task solving paths. The main focus of the discussion was the possibility in inducing responses and motivation. Second, the process of reviewing and evaluating task solving paths and reaching consensus led the improvement of teacher knowledge. Teachers and researchers led changes of teacher knowledge by sharing the knowledge based on previous research and experience, respectively. This ultimately shows the necessity of co-learning between teachers and researchers in teacher education.

Research shows that formative assessment has a more powerful effect on student learning than summative assessment. This case study of an 8th grade algebra classroom focuses on how the implementation of Formative Assessment Lessons (FALs) and the participation in teacher learning communities related to FALs changed in the teacher's instructional practices, over the course of a year, to promote students' mathematical reasoning and justification. Two classroom observations are analyzed to identify how the teacher elicited and built on students' mathematical reasoning, and how the teacher prompted students to respond to and develop one another's mathematical ideas. Findings show that the teacher solicited students' reasoning more often as the academic year progressed, and students also began developing mathematical reasoning in meaningful ways, such as articulating their mathematical thinking, responding to other students' reasoning, and building on those ideas leading by the teacher. However, findings also show that teacher change in teaching practices is complicated and intertwined with various dimensions of teacher development. This study contributes to the understanding of changes in teaching practices, which has significant implications for teacher professional development and frameworks for investigating teacher learning.

The purpose of this study is to develop the questionnaire on pre-service elementary teachers' recognition of self-understanding and change capacity for science education and to investigate their recognitions with it. At the beginning of the study, we made a tool to investigate the self-understanding and change capacity of pre-service elementary teachers through literature review and discussions. The former half of the questionnaire was related to self-understanding with factors such as 'self-concept clarity,' 'career identity' and 'self-efficacy:' 'self-understanding as a pre-service elementary teacher' (12 items) and 'self-understanding as a pre-service elementary science teacher' (12 items). Its latter half was about the change capacity with factors such as 'change sensitivity,' 'goal consciousness,' 'collaboration,' 'reflection,' and 'mastery.' It consisted of three parts: 'general change capacity,' 'change capacity as a pre-service elementary teacher' and 'change capacity as a pre-service elementary science teacher' with 17 items, respectively. With this tool, we surveyed 153 pre-service elementary teachers. The results are as follows: First, pre-service elementary teachers have a positive recognition about self-understanding and change capacity, but the recognition of self-understanding and change capacity as pre-service elementary science teachers were relatively less positive. Second, factors of self-understanding and change capacity as pre-service elementary science teachers have a significant correlation with each other. Especially, there was a high correlation between 'self-efficacy' of self-understanding and 'goal consciousness' and 'mastery' of change capacity. Based on these results, some implications for self-understanding and change capacity related to science education were discussed.

This Qualitative study investigated a preservice teacher's developing views of learning with the influence of constructivist epistemology taught in the Math, Science, and Technology Education (MSAT) Master of Education (M. Ed.) preservice teacher education program. The MSAT teacher education program employs constructivist aspects of teacher education and generates applications of constructivism to the practice of teaching, as revealed by faculty interview data. It is important at this point to emphasize that there are significant epistemological and ontological differences between different versions of educational constructivism (i.e., individual, radical, and social constructivism) and that these differences imply different pedagogical practices. For the 16 preservice teachers included in a larger study, the epistemological and ontological characteristics for each teacher's developing views of learning were identified through four in-depth interviews. Data from interviews were used to construct a constructivist profile for each preservice teacher's views of learning (i.e., a profile containing ontological beliefs, epistemological commitments, and pedagogical beliefs). Of the sixteen participants in the larger study, five significantly changed ontological and epistemological beliefs and eleven did not. Profile changes for the five who did change also resulted in changes in their conceptions of science teaching and learning (CSTL). In this article, one of the five teachers case was presented with rich quotes. This case study documents how a preservice teacher transferred his ontological and epistemological beliefs to his pedagogical beliefs and maintained the consistency between his philosophical beliefs and CSTL. It also demonstrated implications that changes in components for an educational constructivist profile have for a preservice teacher's view of himself as teacher. Data indicated the possibility that a constructivist-oriented preservice teacher education program can influence students' conceptions of science teaching and learning by explicitly introducing constructivism as an epistemology rather than as a specific method of instruction. Implications for both instructional practices of teacher education programmes and research are discussed.

For the current study, five Asian English teachers participated in their case studies to investigate an in-depth understanding of their beliefs about teaching and learning English as a foreign language. Data were collected through structured and unstructured interviews, written documents, observations of teacher-participants' micro teaching, a research methodology journal and a self-reflection journal. This study described the beliefs that Asian English teachers brought to the teacher preparation program and examined to see if these teacher-participants who were involved in case studies perceived change in their beliefs. The study found that formal and informal learning experiences greatly shaped the way teacher-participants' beliefs about the way learning and teaching ought to be. In addition, early experiences of learning and teaching influenced teacher-participants' change in beliefs.

The purpose of this study was to investigate the influences of organizational culture and childcare teachers' job satisfaction on their intention to change jobs. The participants of this study were 290 childcare teachers from the Busan and Gyeongnam areas. The instruments used in this study were the Organizational Culture Scale (4 factors with 16 items), Childcare Teacher's Job Satisfaction Scale (6 factors with 40 items), and Childcare Teacher's Intention to Change Jobs Scale (1 factor with 7 items). The data were analyzed by descriptive statistics, one-way analysis of variance, Pearson's product moment correlation, and stepwise multiple regression with SPSS ver. 21.0 software. The results were as follows: First, the higher childcare teachers' intention to change jobs, the lower was their monthly income, age, and career level, and the total number of children that they had to serve. Second, there were significant positive correlations between childcare teachers' intention to change jobs and their innovative, collective, and rational organizational culture. Further, there were significant negative correlations between childcare teachers' intention to change jobs and hierarchical organizational culture. and between childcare teachers' intention to change jobs and their job satisfaction. Finally, childcare teachers' intention to change jobs was found to be 46% about job satisfaction and organizational culture and was explained the most by the director's childcare center management. This study primarily suggests that a director's role is important in the lowering of childcare teacher's intention to change jobs.

This study explored the relationship between argumentation and the conceptual change model in a science teacher's explanations. Ten audiotape recordings (about 9 hours) collected in a high school physics classroom were all transcribed. The transcripts were analyzed using the components of Toulmin's argument framework and two constructs of the conceptual change model: the status of a conception, and the conceptual ecology. This analysis reveals that there are dynamic relationships among Toulmin's argument components, the status of a conception, and the conceptual ecology. The episode extracted from the transcripts shows the science teacher's explanations in the flow of classroom discourse, as directed and guided by her, presenting the intelligibility or plausibility of a conception by using warrants or backings such as examples or anomalies, two components of conceptual ecology.

The authors examined a college mathematics professor's change process in teaching practice by analyzing the teacher's reflective journal. Her change engaged cooperative learning method in a college Algebra course and was geared toward the reform-oriented methods. The change processes were revealed as a bumpy road that was full of struggles and challenges to both the teacher and students. The analysis also showed that a reflective journey needed a proper means and support system from a teacher's environment such as institution. This research clearly showed that brining a genuine change in teaching practice toward a broad educational goal was a combined effort among the participants of education.

The objective of this study was to investigate whether childcare teachers' job satisfaction plays a mediating role between their intention to change jobs and directors' emotional leadership. The participants of this study were 282 childcare teachers in Seoul. The instruments for this study were Director's Emotional Leadership Scale (2 factors with 18 items), Childcare Teacher's Job Satisfaction Scale (K-CTJSS, 6 factors with 40 items), and Childcare Teacher's Intention to Change Jobs Scale (1 factor with 7 items). These instruments were verified by Cronbach's ${\alpha}$ as a reliability and factor analysis as a validity. The data were analysed by Pearson's productive correlation, stepwise multiple regression and path analysis by the SPSS ver. 20.0 and AMOS ver. 20.0. The results were as follows: First, there were significant negative correlations between directors' emotional leadership and childcare teachers' intention to change jobs, and between childcare teachers' job satisfaction and their intention to change jobs, whereas there were significant positive correlations between directors' emotional leadership and childcare teachers' job satisfaction. Second, the directors' emotional leadership was explained by 22% and the childcare teachers' job satisfaction was explained by 9% of their intention to change jobs. Last, the childcare teachers' job satisfaction mediated between the directors' emotional leadership and childcare teachers' intention to change jobs.
