The purpose of this study was to develop an inquiry-based professional development program for in-service secondary science teachers and to investigate it's application. The inquiry-based professional development program was reconstructed based on SSCS problem-solving model, which is composed of 4 stages of search, solve, create, and share. The 28 science teachers' understanding of the SSCS program were investigated as implementing the program. As a result of this study, 8 SSCS modules have developed as the science teachers have searched, solved, created, and shared various situated problems. The science teachers found themselves to have positive perception of SSCS program. The SSCS program was effective in changing the learners' teaching/learning attitude and to develop individual scientific thinking. To make the SSCS problem solving successful and more effective, both science teachers' professionalism and pedagogical knowledge for selecting topic as the levels of learner should be considered.

The purpose of this study was to search pre-service teachers?and chemistry teachers?conceptions related to electrolysis process by predicting electrolysis products in NaI solution. A questionnaire developed by the researchers and following interviews were adopted for the research. By the methods, the conceptions of the groups were compared. Also, the relationship between their conceptions and explanations of chemistry II textbooks and general chemistry books was examined. From the analysis, it was found that most of the pre-service teachers had difficulties in using standard electrode potential when they predicted products of electrolysis. Most of the chemistry teachers could use standard electrode potential, but it was difficult to understand water electrolysis in redox reaction. The explanations of chemistry II textbooks also contained misconceptions.

This study aims to investigate how the university educational programs about quadratic curves are operated in relation to the high school curriculum and what their effects may be, and the degree of understanding for the prospective and current teachers of the mathematical content knowledge about quadratic curves. To solve this research questions, we randomly selected three universities and one high school. Then we investigated the curricula of each department of mathematics education, compared them with the high school curricula, and conducted surveys of the professors' and students' conception on how much mathematical content knowledge they need to know about quadratic curves. The study resulted in the following conclusions. First, the curriculum on the subject of quadratic curves in the college of education is closely connected to the high school programs. This study's results showed that the college of education's curriculum includes a series of lectures regarding quadratic curves, and that within them, the mathematical content about quadratic curves associated with high school mathematics was thoroughly covered. Also, a large number of students who attended the lecture reported a significant increase in their understanding in regards to the quadratic curves. Second, it is strongly recommended to strengthen the connection between the college of education's curriculum and the actual high school education field. The prospective teachers think that there is a substantial need to learn about the quadratic curves because it is closely connected with the high school curriculum. But they find it challenging to put what they were taught into practical use in the high school education field, and feel that an improvement in this area is much needed. Third, it is necessary to promote, encourage and support the voluntary efforts to expand the range of the content knowledge in quadratic curves to cover the academic content associated with the high school mathematics.

This study analyzed characteristics which emerged while 45 secondary school teachers observed a video clip about a statistics instruction. The aim of this study based on the analysis was to deduct implications in terms of the various means which would enhance teachers' knowledge in teaching statistics and assist in designing statistics education programs for teachers and professional development initiatives. To achieve this goal, this research firstly developed framework descriptors which provided this study with theoretical foundations to investigate what characteristics appeared in the teachers' observation. Secondly, this study probed the observation results from the teachers in the light of the framework. Therefore, some issues in the teacher education program for teaching statistics were thirdly identified in the categories of 'focus of instruction', 'role of the teacher and discourse' and 'data and technology' based on the analysis. This research inspires the elaboration of exactly what features effective statistics classes have through the framework descriptors and additionally the elucidation of essential matters relevant to statistics education on the basis of the issues.

This study is aimed to determine whether there is any meaningful correlation between predictors and is intended to examine the relative influences that the pedagogical content knowledge of science teaching, scientific attitudes, science teaching intentions have on their science teaching efficacy. The results, showed that the childcare center teachers' pedagogical content knowledge of science teaching, scientific attitudes, science teaching intentions, and science teaching efficacy are all correlated with each other. The teachers' science teaching efficacy are predicted by their scientific attitudes, science teaching intentions, and pedagogical content knowledge of science teaching-learning methods. Specifically, for teachers of 0 to 2-year-olds, their science teaching efficacy is predicted by their science teaching intentions and scientific attitudes. For teachers of 3 to 5-year-olds, their science teaching is affected by their scientific attitudes and their pedagogical content knowledge.

This study examines the effects of mindfulness training on job stress, burnout, and teacher efficacy for middle school and high school teachers. For this study, twenty-four middle school and high school teachers were divided into experimental and control groups. Data analysis was performed using a Mixed ANOVA for teacher's job stress, burnout, and teacher efficacy according to pre-training, post-training and delayed post-training periods. As a result, we found support for time interval and between-group interaction effects for all the dependent variables. In order to investigate any delayed effects, a t-test was performed to analyze measurements taken one month after the completion of training period. The delayed post-training results indicated a significant effect between pre and post scores, meaning the program effects were sustained. Therefore, this study indicates that the mindfulness training program implemented in this research is an effective method for preventing job stress and burnout, as well as influencing the efficiency of work performance for middle school and high school teachers.

The purpose of this study was to general needs and identify the educational needs for teaching competency of home economics teachers. based on their perception on teaching competency revealed in Previous studies. Data were collected from 1,104 schools selected by stratified sampling. based on school district, ranking and size. The 616 items of survey materials were collected from 417 schools and the levels of importance and performance were measured on Likert scale with 7- and 5- points, respectively. The analysis reveled that the educational needs for improving teaching competency were high in the following three areas out of seven areas. 1) interfacing ability with the local community and diverse human resources. 2) ability managing space and materials for learning 3) ability diversifying lesson development and evaluation ability. In addition. diversifying and professionalizing present development program for home economics teachers made higher score than improving education program for home economics teachers. These two needs of teachers showed significant differences according to their educational experiences and foundation types of their schools.

The goals of this study are basically to analyze the lectures related to mathematics education in national universities of education and in education training institutes, and ultimately to suggest the collaboration in the lectures related to mathematics education in national universities of education and education training institutes. In order to achieve the above goals, five universities were selected. Summing up these results, we suggest several ways to collaborate the mathematics education lectures in national universities of education and education training institutes. First, the training education in the national university of education has to offer more lectures which deal with the theory related with mathematical education and the fundamental area of mathematics. In addition to this, teaching in contents in terms of the area has to focus on the background knowledge related to the teaching contents. Second, based on the training education, the assigned education training institute has to reflect the periodical and social condition. In addition to this, it has to reflect the real condition around the school environment. With those efforts it has to make new kinds of lectures which concentrate on the recent trend or the understanding of the theory related with mathematical education. In this case, both obligatory and elective courses have to be offered. Third, the education training institute responsible for the staff development program has to open lectures with the contexts of real time teaching activities based on the experiences of the teachers. In this case, one or two particular subjects have to be dealt with in depth and lecturers have to be selected who are suitable for the lectures.

This study aims to confirm whether both the emotional labour and job stress contribute to the turnover intention of infant teacher. The correlation analysis and parametric analysis were sequentially performed for our study. Analyzed results showed that the emotional labour was related to the job stress and turnover. Also, a statistical significance between the job stress and turnover intention was observed. Besides, the job stress partially mediated the relation between the emotional labour and turnover intention. Nsidering that the emotional labor of teacher caring or lived with infants occurred inevitably, our study proposed three approaches to reduce the job stress that partially mediated relation between the emotional labour and turnover intention. Generally, the infant teacher with excellent qualification produced the good education. Therefore, we suggested that the it was necessary that a work environment had been improved and working motivation was ameliorated to employ the infant teacher with excellent qualification.

Science class is the starting point of science education where science teacher and students meet together to teach and learn science. Therefore successful science class is the main concern of various educational partakers, such as teachers, students, parents, school administrators, and science education researchers. In order to find what is important among the teaching abilities of science teachers, a survey was conducted to the various educational partakers. As the result of survey, students chose 'progressing a lesson' and 'teacher's attitude' are important, and in-service teachers chose 'analyzing learner characteristics and curriculum' and 'teacher-student interaction' are important, while the pre-service teachers and parents chose 'teacher-student interaction' and 'progressing a lesson' are important. In addition, the school administrators chose 'setting up teaching-learning strategy' and science education researchers chose 'understanding curriculum and developing teaching-learning method' is important along with 'analyzing learner characteristics and curriculum.' In the communication on science education among different educational partakers, these result can be used as the basic information to understand the different perspectives on a science class.
