This paper summarizes findings from investigations into the development and application of English bible study materials for middle school students in two local churches in Seoul, Korea. Six pre-service Christian English teachers have participated in the development of the materials. After the application of the new materials, the pre-service teachers' and bible study teachers' perception of the new materials have been investigated. To analyze the data, the pre-service teachers and bible study teachers were interviewed. The interview data was recorded, transcribed and analyzed based on content analysis method. The findings indicated that the pre-service teachers' church service learning gave them a sense of satisfaction and it also helped them develop professionalism in teacher education. To both the pre-service teachers and bible study teachers, keeping balance between bible teaching and English teaching was found to be a difficult task. The fact that the themes in the new materials are closely related to the lives of the students has been positively evaluated by the bible study teachers.

As the importance of technology increases, the need for TPACK, an knowledge for pre-service teachers, to integrate technology into education has increased. In order to improve TPACK of pre-service teachers, programming-based TPACK education program was developed. However, the developed educational program did not affect the self-efficacy of pre-service teachers. In order to solve this problem, in this study, the improved TPACK-P education program was applied to pre-service teachers to verify the change of self-efficacy. As a result, the improved TPACK-P education program was effective in the development of self-efficacy of pre-service teachers. In detail, pre-teacher's self-confidence and preference of task difficulty were significantly improved than previous. The TPACK-P education program, which is improved through this, confirms that the pre-service teacher promotes the integration of technology into the classroom rather than the existing education program.

The purpose this research was to develop the practicum-affiliated coursework for pre-service chemistry teachers to enhance their instructional professionalism. The researchers developed the syllabus and the materials of the practicum-affiliated coursework and opened the class 'Practice of Chemistry Lesson' for the pre-service chemistry teachers who were expected to participate in the practicum. Semi-constructed individual interviews revealed that pre-service chemistry teachers thought the developed coursework, which linked science education theory and practice, helped them to develop educational connoisseurship about good science class and to be prepared practically to the practicum, and as the result, they could enhance their teaching ability. The result identified that the reconstruction of the practicum experience through the process of 5 steps of the curriculum could develop the instructional professionalism of pre-service chemistry teachers.

The purposes of this study were to examine what kinds of educational activities were carried out during the practice teaching based on CoRe and to identify the role of CoRe and its influence on the development of expertise of student teachers. This study was performed as qualitative case study. The subjects of this study were one practice supervisor teacher and two student teachers. Data were collected through recording CoRe discussion process, student teachers' instructional scene, and semi-constructed interview, and analyzed by an inductive method. Student teachers noticed their own misconceptions, and clarified the concepts based on CoRe during the discussion with supervisor teacher. They also supplemented their lack of knowledge and made up new strategies through the process of sharing their ideas. During the discussion, the supervisor teacher conveyed his teaching experience based on his own orientations toward science teaching. In this course, CoRe plays roles as follows. Firstly, CoRe played a role as guiding supervisor teacher's coaching process. Secondly, CoRe helped for the supervisor teacher to recognize their own PCK. Thirdly, CoRe served as a tool of helping their communication. In turn CoRe proved to be a useful frame for teaching student teachers during practice teaching. Student teachers were provided with a useful framework for preparing lessons by developing CoRe for the topic they teach. Developing CoRe with supervisor teacher at the planning stage of lessons enhenced student-teachers' subject matter knowledge and their PCK including knowledge of science curricula and knowledge of student's understanding of science. Also student teachers understood the components of PCK and experienced the positive understanding toward students, teaching activities, and themselves as a science teacher.
