  • 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.

  • 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 the study is to develop an effective model of a science teachers' professional development program. This study consists of two parts: (1) the theoretical review of science teachers' professional development and (2) a case study of a science teachers' professional development programme in the UK. After reviewing recent research on pedagogical content knowledge and new approaches to educational research, the following suggestions emerged: (1) Continuing Professional Development(CPD) should be embedded in teachers' real practice in the classroom and (2) embedded in the everyday life of learners' within the community. (3) CPD should support the development of teachers' communities of professional practice. The case study of 'CPD through Portfolios of Evidence' in the British programme indicated that collecting explicit evidence of good practice in the classroom and establishing agreement as to what constitutes good practice in a teachers' community helped teachers' professional development. Finally, what emerged from the case study of the CPD programme in the UK and the theoretical review of PCK was the following. An effective CPD model of science teachers should comprise these three stages: (1) providing opportunities of professional development, (2) changing practice in the classroom and research, and (3) spreading and sustaining change. The whole process is circular.

  • This study explored pre-service teachers' mental models about eclipse phenomena to investigate their understandings on the earth science concept needed f3r an integrated approach. We conducted in-depth interviews with two different contexts on 30 secondary and 36 primary pre-service teachers participants, and analyzed phenomenological primitives (p-prims) and facets of causal explanations about eclipses. Based on this study, we identified four different levels of mental models about eclipses. Four mental models were categorized as (1) Screening model, (2) Orbital plane model, (3) Hybrid model, and (4) Shadow cast model. Screening model is a flawed mental model, orbital plane model is an incomplete correct mental model, and shadow cast model is a scientifically correct mental model. Hybrid model, composite of two or more mental models, use multiple mental models simultaneously. Orbital plane model was the most widespread mental model in secondary pre-service teachers group, whereas screening model was used frequently in primary group. It was found that the level of mental model could be determined by the level of facet and p-prims. We confirmed context sensitivity of the mental models and perceived the necessity of integrated approaches to promote progression of mental models. Implications of our findings for enhancing pre-service science teachers' topic-specific pedagogical content knowledge (PCK) associated with eclipse phenomena are also discussed here.

  • The following experiment was designed to test the students' involvement in the interactive activities and objectives of the relevant chapters in the newly revised curriculum of 2007. The experiment was carried out with the purpose of understanding the level of participation of the Grade 9 students who have successfully completed the Grade 8 "Choice of Food and Diet" and "Table Manners and Dining Etiquette" courses with classified materials such as tables/diagrams/pictures, reading, and activity resources from Technology Home Economics textbooks. The chapters "Choice of Food and Diet" and "Food Preparation and Etiquette" generally emphasize the practical and experiential part of domestic life through using various activity resources; while the tables/diagrams/pictures and reading materials do not provide the students with first-hand experience, they support the students' learning by explaining the basic knowledge required for doing the activities and solving various problems. Within the main training courses, the objectives which the students achieved the highest marks were(in a descending order) "Table Manners and Dining Etiquette" (3.24), "Checking Nutrition Labels, Food Expiration Date, Country of Origin When Buying Food" (3.18), Additionally "Making Food" and "Planning a Healthy, Balanced Diet" hardly met the goals, the result of which shows clear relations to the well achieved objectives from the list of in-class activities that students directly participated in. Therefore, in order to increase the students' interest in the Food and Diet section of Technology Home Economics textbooks, it is recommended to encourage the students to actively engage in the class activities by developing various learning resources and teacher education/pedagogical materials, rather than following the conventional lecture-based teaching methods.

  • The purpose of this study is to investigate pre-service science teachers' difficulties in the 'inquiry mentoring' program, which was developed to improve pre-service science teachers' inquiry teaching ability. For this study, I developed the 'inquiry mentoring' program in which pre-service science teachers taught high school students. This program was adapted for 2.5 months, and 45 pre-service science teachers participated and taught 44 high school students. During this program, pre-service science teachers kept 'mentor diaries' and wrote 'mentoring reports' at the end of the program. Interviews were conducted with all pre-service science teachers. Results are as follows: first, pre-service science teachers thought that the difficulties in inquiry mentoring resulted from their inadequacy (mentor factor) than students' inadequacy (mentee factor). Second, pre-service science teachers perceived their lack of cognitive ability, inquiry ability and teaching ability as a mentor factor. Third, pre-service science teachers thought that they had difficulties in students' differences and lack of activity as a mentee factor. Fourth, they described difficulties caused by emotional distance as well as physical distance as an interaction factor. They also mentioned the difficulties related to teaching range and online interaction. Fifth, pre-service science teachers expressed a sense of frustration with the inquiry environment. Additionally, some implications were discussed for pre-service science teacher education through the 'inquiry mentoring' program.

  • This study investigated how the unique educational contexts in the Republic of Korea (RK) impacted two science teachers' teaching practices in a public middle school and what the science teaching experience means to them. In particular, we explored how the middle school science teachers decide pedagogical approaches to use in their teaching based on classroom climate, students' attitude toward learning science, school curriculum and classroom culture. Using a phenomenological research approach, we analyzed classroom observation data and interview data to interpret the teachers' science teaching experience. Results of the study showed that the teachers' practice was dominantly affected by two external factors. First, the teachers' teaching practice was affected by the amount of science content knowledge they need to cover within a given class time. Second, the teachers' teaching practice was affected by students' attitudes toward science learning and their science preparedness in private tutoring centers. Implications of the study results are discussed in the paper.

  • Teachers' philosophies have not been emphasized enough in the current teacher education curriculum even though teacher's philosophy palys a critical role in schools and classrooms. The examination on pre-service teachers' teaching philosophies is necessary to improve teacher education curriculum so that teaching philosophies are often discussed in the courses of 'pedagogical content knowledge' as well as 'general education.' Therefore, the current study investigated 44 pre-service teachers' teaching philosophies, their sub domains, and relationships among the sub domains. The previous studies regarding mathematics teacher's teaching philosophy were more about 'teacher's belief' and employed deductive inference approach using surveys or questionnaires. These studies commonly pointed out that there were three major domains of 'belief on mathematics itself,' 'belief on teaching mathematics,' and 'belief on learning mathematics.' As these three domains of teacher's philosophy has been strengthened, there were very few studies examining the other potential domains of teacher's teaching philosophy. According to the findings of the present study, which employed inductive inference approach and pre-service teachers' free essay writing assignment, 'belief on teacher's role in mathematics classroom,' 'belief on the purpose of mathematics education,' and 'motivation to be a mathematics teacher' were additionally illuminated as sub domains of teacher's teaching philosophy. Moreover, the interrelationship among the sub-areas of teacher's teaching philosophy was disclosed. Specifically, 'belief on the purpose of mathematics education' and 'motivation to be a mathematics teacher' influenced the other sub domains. This implies that the relationships among the sub domains of teacher's teaching philosophy were more likely to be causal and vertical relationships rather than independent and parallel relationships. Finally, the findings from the current study provide implications indicating how pre-service teachers' teaching philosophies might be established in mathematics education courses for future research and education.

  • The purpose of this study is to probe secondary science teachers' perception on scientific models and modeling. A total of 50 experienced science teachers were surveyed with 10 open-ended questions about several aspects of models and modeling: definition, examples, purpose, multiplicity, changeability, design/construction, evaluation and beliefs in the use of models and modeling as a teaching tool. The analysis of the data shows the following results: 1) understanding of models and modeling held by a majority of experienced secondary science teachers was far from that of experts as they concentrated on a model's superficial, representative, and visual functions, 2) when it comes to their view toward the use of a model, a model does not remain in the stage of 'doing science' but in the stage of being a subsidiary teaching tool for the teacher's explaining and the students' understanding of scientific concepts, 3) the subjects they majored in made meaningful differences in their contextual understanding of models and modeling, 4) though most of the teachers acknowledged the importance of teaching about models and modeling, even a lot of them showed a negative position toward the opinion that they are willing to apply modeling to their classes. Implications of the results were discussed in terms of intervention in order to enhance secondary science teachers' understanding and pedagogical content knowledge of models and modeling.
