In this study, we investigated the characteristics of the pedagogical content knowledge (PCK) components and their integrations in the processes of developing performance assessment tasks of pre-service chemistry teachers who participated in the constructive performance assessment workshop. Eight pre-service teachers participated in this study. After three weeks of the constructivist performance assessment workshop, they developed their own performance assessment tasks. The think-aloud method was used to investigate their developing processes. Their activities were recorded and videotaped, and semi-structured interviews were also conducted. The analysis of the results revealed that the PCK component considered in the planning step showed similar frequencies for assessment, instructional strategies, students, and subject matter components. In the embodying step, assessment component was most frequent. In the discussion step, the frequencies for assessment, instructional strategies, and students components were similar. However, curriculum component and the subcomponent of science process skill were rarely used. The integrations among the PCK components were found to be centered on the instructional strategies component in the planning step and the students component in the embodying and discussion step. However, curriculum and subject matter components were rarely integrated with other PCK components. On the basis of the results, educational implications are discussed.

This study investigated the interactions among the PCK components of pre-service secondary chemistry teachers considered in the processes of making written test items individually and in small groups. The processes of making written test items individually for 8 pre-service teachers was studied through the think-aloud method. The analysis of the results revealed that the 'assessment in science education' of the five PCK components was most frequently used in making test items. 'Curriculum for science education,' 'subject matter knowledge,' and 'students' were also frequently used although fewer than the previous component. However, 'instructional strategies and instruction for science education' was hardly used. The integrations between two or three components with various types were frequently found. However, integrations among four to five components were not found. The processes of making written test items in two small groups consisting of four pre-service teachers were observed. The analysis of the results revealed that the PCK components used in small groups were similar to those in the individual processes. However, 'curriculum for science education' was less frequently used, and the numbers of subcategories used at a relatively high frequency increased from other four components in small groups. In the aspects of integration, the proportion of the integrations between two components decreased and that for three components increased compared with those in the individual processes. The integrations among four or five components were also newly found. However, the integrations of 'curriculum for science education' with the other components were less frequently found. The integrations of 'instructional strategies and instruction for science education' with other components were still hardly found.

The aim of this paper is to explore and understand, using in-depth interviews, the participant's enthusiasm for and involvement in studying mathematics and the deeper nature of his/her interest in mathematics teaching. In addition a larger aim is to understand how the individual's interest in mathematics and teaching are linked to his/her larger personal fulfillment. We conducted in-depth interviews with 4 pre-service teachers' subjective experiences focusing on deep motivation, pedagogical content knowledge, inner vision. Interviews focus much more on the participant's spontaneous feeling, consciousness, and state as these arise in the interview, and on past foiling, consciousness and state as they appear to the participant subjectively retrospectively in his/her memory. The output of this research consists of 2 portraits out of 4 individual participants, highlighting and conceptually developing the specific aspects under study; different ways in which individuals' involvement with the subject area affects their motivation, inner visions and academic efforts toward becoming teachers. Larger aspects of pre-service teachers' subjective experiences were sketched by contrasting the two cases. Several suggestions were put at the end to enhance mathematics education concerning curriculum development.

The purpose of this research is to explore types of pedagogical content knowledge (PCK, hereafter) for effective science teaching. In this research, we explored three science teachers' PCK on light, who were effective in teaching the topic with particular students. The data analysis consisted of identifying the three teachers' unique PCK and ways to improve each teaching episode through the teacher meetings. These analyses, which consisted of verbal exchanges among the participants, were identified on the basis of our understanding. Using grounded theory methods, the types of science PCK drawn from this research are: (1) teaching through curriculum reconstruction, (2) teaching to help students build their own explanation models about surrounding nature, (3) teaching for learning the social language of science, (4) teaching to motivate students' learning needs based on relevance of science to students, (5) teaching through lowering students' learning demand by providing scaffolding, (6) teaching based on the teacher's understanding of students, (7) teaching through inquiry with argumentation, (8) teaching through reification of abstract science concepts, and (9) teaching none marginalized science. Common features of science teachers with quality PCK and their professionalism in teaching are discussed.

In this study, we investigated the characteristics of the PCK components in the chemistry units of middle school science teacher's guidebooks developed under the 2009 Revised National Curriculum. The analysis of the results revealed that the sub-components of topic-specific strategies, vertical articulation, and lesson objectives were systematically handled in most teacher's guidebooks. However, subject-specific strategies, assessment methods, and curricular changes were mainly dealt with only in the general guidelines. Experiments and inquiries, assessment questions, and assessment dimensions were lack of constructivist approaches in the aspect of presented contents or forms. Horizontal articulation and knowledge of students were either lacked in relevant content or presented in the form of simple presentation. Concepts and theories accounted for the largest proportion of teachers' guidebooks, but some of them were beyond appropriate levels. On the bases of the results, the implications for the development of the teacher's guidebooks are discussed.

This thesis has a research focus in effectively Practicing cooperative instruction where teacher-librarians play a role. The cooperative Instruction means to practice cooperatively with the subject teachers and teacher-librarians, in teaching subject matters(Korean, English, Social studies. Science, History, and so forth), using the school library. This thesis presents three steps by theory-model-support for a practice method through developing a cooperative instruction model. This is based on curriculum which is an axis of school education and an instructional design theory which is a base theory for subject matters.

This study investigated the level of academic passion for elementary school teachers' science pedagogical content knowledge (PCK) and examined the factors that influence the passion. To this end, 161 elementary school teachers in Seoul were selected, and academic passion tests were then administered to evaluate their academic passion for science subject matter knowledge and science pedagogical knowledge. Individual in-depth interviews were also conducted with some of the participating teachers. The results revealed that 'importance' and 'harmonious passion' for learning science subject matter knowledge and science pedagogical knowledge were found at a high level. However, 'time/energy investment' and 'obsessive passion' for learning the knowledge were slightly higher or lower than normal. The 'like' for learning science subject matter knowledge was relatively high, but the 'like' for learning science pedagogical knowledge was slightly higher than normal. The differences in academic passion for science subject matter knowledge and science pedagogical knowledge were greater according to advanced major at undergraduate than teaching career. The teachers evenly selected some factors that influenced their academic passion for science subject matter knowledge and science pedagogical knowledge. These identified characteristics included 'individual interest', 'high school track', 'experience in advanced major at undergraduate', 'experience in science-related graduate school', 'experience teaching science in elementary school', 'experience teaching science at the gifted education institute', 'experience in charge of science subject teacher', 'experience in science-related teacher training', 'experience in developing science-related teaching and learning materials', 'experience in charge of science or science-gifted related work', and 'experience in a science-related teacher community'. However, a slight difference was noted in the selection ratio depending on advanced major at undergraduate. Based on these results, the practical implications for improving their academic passion for science PCK are suggested.

This study investigated the level of academic passion for pre-service elementary teachers' science pedagogical content knowledge (PCK) and the factors that influence the passion. To this end, 182 first to fourth grade students in advanced non-science majors who were taking science-related courses in the second semester were selected, and two tests were then administered to evaluate their academic passions for science subject matter knowledge and science pedagogical knowledge. Individual in-depth interviews were also conducted with some of the participants. It was found that the factors such as "importance" and "harmonious passion" for learning science subject matter knowledge and science pedagogical knowledge were found at a high level. On the other hand, the factors such as "like" and "investment of time and energy" were slightly higher than normal, and the factor such as "obsessive passion" was slightly lower than normal. The differences in academic passion for science subject matter knowledge and science pedagogical knowledge were greater according to the high school track than the grade. The pre-service elementary teachers selected more often the factors such as "individual interests", "high school track", "contents of science-related courses at the university of education", "characteristics of professor in charge of science-related courses at the university of education", and "experience in teaching practicum" as the factors that influenced their academic passion for science subject matter knowledge and science pedagogical knowledge. However, there was a slight difference in the selection ratio depending on the high school track.
