Many studies on the professional development of science teachers demonstrated that induction teachers' conceptions of teaching science are important factors in developing their professionalism. The present study was conducted to describe in detail the progress of two science induction teachers, June and Mike, towards conceptual change teaching, and to investigate secondary induction science teachers' conceptions of teaching science by analysing their conceptual ecologies. The study was interpretive, using multiple data sources to achieve a triangulation of data. Both June and Mike held strongly positive learning in their views of knowledge and science. Holding positivist views of knowledge and of science is likely to be a major obstacle for anyone coming to understand constructivism and its implications in teaching for conceptual change. This argument resonates in several key ways with the teachers' cases, even though I recognize differences between scenario and teachers, and between teachers themselves.

Developing pedagogical content knowledge (PCK) has been emphasized for teacher's professionalism and it should be done from systematic teacher training courses. In this study, we investigated changes of elementary pre-service teachers' PCK of science teaching and motivational strategies before and after a training course. For the analysis of pre-service teachers' PCK, their lesson plans, surveys, and interviews were collected. According to the results, in the beginning of the semester, pre-service teachers in the experimental group usually used didactic or combination of didactic and inquiry teaching strategies and a few pre-service teachers used inquiry or discovery teaching strategies when making lesson plans. However, at the end of the semester many pre-service teachers used inquiry teaching strategies in their lessons which included activities of asking students' prior knowledge, conducing experiments, finding conclusion, and comparing teachers' explanations with students' explanations. Regarding motivational strategies, in the beginning of the semester they focused using activities to create student's emotional interest in science lesson but at the end they used other strategies to create positive atmosphere for learning, capture intellectual interest in science, and connect science to students' everyday lives. The changes in pre-service teachers' PCK in the experimental group was meaningful because there was less change in pre-service teachers' PCK in the control group. This study implies the need for effective professional development programs for developing pre-service teachers' PCK.

In this study, we analyzed the influences of lecture design using CoRe upon the professor's teaching professionalism in the aspects of pedagogical content knowledge (PCK). The participants are three professors from the college of science-engineering located in Chungcheong-do. After collecting their syllabi, we observed their lecture and conducted the orientation. Afterward, we collected the CoRes which they prepared before the lecture. Then we observed their lecture and conducted semi-structured interviews. This process was carried out twice. We analyzed their syllabi, CoRes, videotaped lectures, field notes, the teaching materials, and interview transcripts. The results revealed that professors not only clarified the learning objectives and the characteristics of students but also reflected them in the lecture. In addition, they established the teaching strategies according to the characteristics of contents in the unit. As they recognized the necessity of understanding students' achievement, they selected the assessment method and applied it in the lecture. In some cases, however, they lacked presenting learning objectives specifically and explained students' misconceptions without inducing new concepts. They also presented a shortage of considering students' prior knowledge. They lacked providing students with an opportunity to participate in lectures, and their assessment method was not effective. Based on the results, we discussed implications to improve teaching professionalism using CoRe.

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.

The purpose of this study was to analyze the perceptions of the students about expectation and performance on the elementary teachers' science teaching. For this study, questionnaires were made based on the advanced article, and conducted to 279 elementary school students. The collected data were analyzed by the t-test, ANOVA, and $Scheff{\grave{e}}$. The results of this study were as follows: The perceptions of the students on the elementary teachers performance can not reach to those of their expectation. There was statistically significant difference in the some of the sub-domains of expectation and performance according to personal backgrounds (gender, grade, and interest toward science class). Based on the result of this study, implications to improve teachers' professionalism about science teaching were suggested.

The purpose of this study was to examine whether the new introduction of elementary science experiment specialist is appropriate under the current situation of serious emphasis of the importance in science experiments in elementary science in Korea. For this study, the survey items were developed twice through the preliminary study. The results show that most elementary teachers consider the importance of experiment in elementary science and the critical role of science experiments to increase students' curiosity and scientific understanding. About 80% of the teachers stressed the professionalism in elementary science. Although 65% of the teachers believed their having basic professionalism, 53% of them appealed the difficulty in teaching science experiments to students. Nevertheless, 67.5% of the teachers opposed to the idea of teaching elementary science in separation between experiment and theory in science, and only 8% of them agreed the idea of induction or adoption of the college graduates majoring in science and engineering, or holding the secondary teacher's certificate. Further, over 60% of the teachers responded no necessity of inducing the new policy of elementary science specialist. Many numbers of teachers revealed their serious worries about the new policy because of their past experience to suffer from the side effects of inducing the teachers with secondary teacher certificate to the elementary school. In particular, they also made a proposal to make a good use of the current system of exclusive elementary science teacher in Korea. The educational implication and suggestions for policy making were discussed.

Scientific creativity is necessary for all ordinary students in ordinary school settings. In this study, a practical format for teaching scientific creativity is suggested, and sample teaching materials based on this format are developed. To facilitate the practical use of the teaching materials in ordinary schools, the model of IS3CA(Iterative Small Scale Scientific Creative Activity) was proposed. Using this format and the proposed teaching materials, a brief in-service program was developed and implemented. Here, the aim is to improve teachers' actual professional ability to develop their own teaching materials rather than just using the pre-developed teaching materials provided by the researcher. Positive responses about the in-service program were collected from the teachers, and the results also showed that the development of teaching materials by teachers was possible. Therefore, I expect that the teaching of scientific creativity by ordinary teachers is possible for ordinary students in ordinary school contexts. Finally, based on the results and experiences of this study, a curriculum for teaching scientific creativity is suggested.

As a case study on the changes of beginning science-gifted education teachers' teaching professionalism through coteaching, this study deeply investigated the change processes in the aspects of pedagogical content knowledge. We selected two beginning teachers whose teaching careers in secondary science-gifted education were less than five years. The teachers planned, performed, and reflected together their science instructions for secondary science-gifted students during nine class hours over three times. We observed coteaching of science instructions of the teachers, and analyzed the taped videos, the materials, the transcripts for discussions between them and in-depth interviews with them, their reflective journals, and researcher's field notes by using the constant comparative method. This study revealed that the coteaching positively changed the two teachers' practical knowledge about the curriculum for science-gifted education, the instructional strategies for science-gifted education, the assessment in science-gifted education, the science-gifted students, and the science contents although there were some limitations. The results suggest that the coteaching will be useful in improving beginning teachers' teaching professionalism, and provide practical implications in finding the ways to use it effectively in science-gifted education.

This study investigated the changes in teaching professionalism of beginning science-gifted education teachers through mentoring in the aspects of pedagogical content knowledge. We selected two beginning teachers whose teaching careers in science-gifted education were less than five years. The teachers planed, performed and reflected on science instructions for secondary science-gifted students through mentoring during nine class hours over three times respectively. We observed their instructions and analyzed the taped videos, the materials, the transcripts for in-depth interviews with mentees, and discussions between mentor and mentee, researcher's field notes by using the constant comparative method. This study revealed that the mentoring, although there were many limitations, positively changed the mentees' practical knowledge about the curriculum for science-gifted education, the instructional strategies for science-gifted education, the assessment in science-gifted education, the science-gifted students, and the science content. These results suggest that the mentoring will be useful in improving the teaching professionalism of beginning science-gifted education teachers and provide meaningful implications in finding the ways to use it effectively in science-gifted education.
