Pedagogical content knowledge (PCK) has been regarded as an indication of science teachers' professionalism. The purpose of this study was to analyze topic-specific PCK of pre-service and in-service science teachers, comparatively. For this purpose, we developed an analytic framework for explicitly documenting science teacher' PCK and applied the framework for analyzing the difference within the same topic and with two different topics. Findings are as follows: (1) With the same topic, there was considerable difference between pre-service and in-service teachers in the components of PCK, not to mention individual difference. (2) In case of two different topics, we did not recognize a tendency of change in PCK, but remarkable differences in PCK were identified between two different topics. This study affirmed the topic specificity of PCK, and discussed a possibility of employing PCK analytic framework and its profile as one of the tools that could be used to develop and assess teachers' professionalism.

This qualitative research investigated how to improve preservice and in-service teacher education programs through in-depth interviews with 10 exemplary science teachers. Data from interviews were used to analyze how the teachers perceived current situations of teacher education and what they suggested as an improvement plan. In terms of preservice teacher education, exemplary teachers argued that teacher education programs should (1) ensure the teacher education program's identity and goals, (2) provide preservice teachers with practical knowledge by translating theory into practice, and (3) secure faculty members who majored in science education. In light of in-service education, the teachers contended that (1) teachers should acknowledge the continuing processes of their own professional development, (2) the content and method of in-service training should incorporate teachers' practical needs in the classroom, and (3) the teaching community should implement a clinical supervision to improve their classroom practices. The central role of teacher (re)education in a successful classroom reform is also discussed.

How a pre-service teacher understands and comments on mathematics instruction can serve as the foundation of her teaching expertise. Given that prospective teachers observe demonstrative mathematics teaching implemented by an in-service teacher and make a comment on it during their practicum period, this paper specified the levels of their ability in commenting on mathematics instruction and explored the characteristics of such levels. It is significant that this paper provides a systematic and comprehensive analysis of such levels in terms of topic, agent, stance, evidence, and alternative perspective. The results of this study showed that the commenting levels may be classified by Level 1 (fragmentary), Level 2 (inspective), and Level 3 (analytical), and that the most frequent level of this study was at Level 2. Multiple regression analysis demonstrated that stance is the most influential in determining the levels of comments among their analytic components. An analysis of the participants' anecdotes showed that the experience of observing demonstrative teaching during the practicum may have impact on the belief of mathematics instruction and self-image as a teacher. Building on these results, this paper provides implications of teacher preparation programs to enhance prospective teachers' ability to analyze elementary mathematics lessons.

In this study, by measuring and analyzing the motivation of prospective mathematics teachers in learning mathematics, we tried to understand the features of prospective teachers' learning motivation and find the implications of developing expertise in terms of learning motivation. Prior research related to learning motivation identifies the three elements that consist of learning motivation as values, self-efficacy, and interest. Based on these elements, a survey tool was developed to investigate the learning motivation of prospective mathematics teachers. This survey was then carried out for 120 students in the mathematics education department of a local college. In addition, the survey asked what methods prospective teachers would choose for motivating their future students. According to the results of this study, the overall motivation of prospective mathematics teachers differed by grade (academic year) and there were significant differences between grades in self-efficacy and interest factors. In addition, the prospective teachers preferred to use interesting materials rather than inform the value of learning mathematics to induce learning motivation. Therefore, it is necessary to enhance this self-efficacy and interest in learning and to provide various material to strengthen this motivation for learning.

The purpose of this study is to find out what their professionalism is and how their expertise grows among Christian alternative school teachers. Professionalism refers to the broad expertise such as specific knowledge, skills, and attitudes needed for a particular profession. The teacher expertise is also closely related to the life cycle of a teacher. The present study collected and analyzed the data using a mixed research method that combined a survey and interview. The survey, which involved 276 Christian alternative school teachers, asked about the current teacher's interest, the importance and retention of each element of professionalism, and, in addition, the level of external efforts and help in developing professionalism. The in-depth interview was conducted on 7 Christian alternative school teachers and identified the meaning of teacher professionalism, teacher quality and competencies, and environment for the professional growth. The results reveal that the professionalism recognized by Christian alternative school teachers is rather complex. It includes communication and relationship, calling and identity in addition to the curriculum and instruction expertise that reconstructs the curriculum from a Christian perspective. It is further found that teachers' decision to respond to the calling, subsequent continuous self-development, the teacher community that embodies such calling and efforts, and the school environment where autonomy and responsibility coexist, are equally important for their professional growth. Thus, in order to promote the professionalism of Christian alternative school teachers more effectively in the future, it would be necessary to provide programs that take the teacher's whole life cycle into account and are also directed to teachers themselves rather than to institutions. Considering the emphasis on the expertise in communication and relations, pre-service teacher education should focus not only on developing subject matter expertise, but also fostering communication and relational skills with students and other school community members.
