A survey was done to figure out the HPLP(health promotion lifestyle profile) of the teachers of health-related disciplines and not-health-related disciplines. 205 teachers in middle and high school were surveyed from 4th February to 2nd April 2003. The results of this study were as follows; 1. The HPLP score of the teachers of health-related disciplines (mean $2.73{\pm}0.44$) was higher than that of the teachers of not-health-related disciplines (mean $2.48{\pm}0.40$). Sub category's mean of the teachers of health-related disciplines was self-realization 2.99, interpersonal-relationship 2.92, health responsibility 2.65, nutrition 2.64, stress management 2.52, exercise 2.27 and that of the teachers of not-health-related disciplines was self-realization 2.84, interpersonal-relationship 2.70, health responsibility 2.24, nutrition 2.39, stress management 2.23, exercise 1.98. 2. When HPLP score were examined according to demographic characteristics, health status and self-efficacy, the results showed that of the teachers of health-related disciplines was higher than that of the teachers of not-health-related disciplines. 3. Gender, degree of grief and depression, and self-efficacy have statistically significant effect on the HPLP score of the teachers of health-related disciplines, and subjective health status, concern about health, degree of stress, and self-efficacy were significant on that of the teachers of not-health-related disciplines. This results were indicated the teachers of health-related disciplines show better role model in health than the teachers of not-health-related disciplines. As self-efficacy is the most important factor on the HPLP score, it is very important to introduce programs to raise self-efficacy of teachers in middle and high school.

This study investigated the relationship between science high school teachers' beliefs of gifted education and classroom practices. The data of this case study were collected from three science teachers who worked in a science high school through qualitative research methods such as interviews and classroom observations. The other various data related to science high school management and the teachers' teaching were collected and analyzed using the constant comparative method. The results of the study are as follows: the teacher of long period in-service experience in science high school had teacher-centered belief, and his classroom practices were matched with his beliefs. The teacher of short period in-service experience in science high school had student-centered belief, and her classroom practices were matched with her beliefs, also. The teacher of medium period in-service experience in science high school had student-centered belief, but her teacher-centered classroom practices were mismatched with her beliefs. From the results, it could conclude that school culture affects on teachers' classroom practices stronger than beliefs. The longer career period of science high school changed easier teachers' beliefs into knowledge education for university entrance examination removed from gifted education. To solve these problems, we suggest the needs of teacher education programs for science high school teachers.

The purpose of this study is to investigate various conceptions of secondary school earth science teachers on some concepts in secondary school earth science courses; wind in cyclone, western intensification of ocean current, westerly wave, greenhouse effect, ozone layer and atmospheric pressure. The subject is 26 in-service teachers of earth science teachers. The results were analyzed on the view of teaching sources for earth science teachers. The results show that earth science teachers have also various misconceptions on some concepts selected in this study. A number of partial understandings were found that were not enough to apply to teaching concepts. Those misconceptions were related to gradient wind on wind in cyclone and frictional force, related to earth rotation on western intensification of ocean current, related to angular momentum conservation and related to the roles of westerly wave. And misconceptions on greenhouse effect are related to main role of greenhouse effect gases, related to sources of ozone gas and phenomenons by atmospheric pressure. The various understanding types found in this study could be apply to teach the selected concepts in secondary school earth science course.

The purpose of this study is to investigate the formation and development of science teachers' practical knowledge by life history. In the sociocultural perspective, a science teacher is a producer and consumer of knowledge. There were two secondary science teachers who participated in this study. Each of them had three to six years experience in teaching. They were familiar with the researchers because they had been to the same university or were colleagues with them in graduate school for several years. The two science teachers had formed their practical knowledge for their professional development based on their biographical backgrounds. Model of Life history and structure of personal practical knowledge were used as analytical tools. As a result, the science teachers' practical knowledge has shown a significant difference in the main concern and weight according to their life contexts. The science teachers' formation of their practical knowledge played a role as an important motive to improve their professionalism based on the teacher's life path. In addition to that, the science teachers' practical knowledge showed a tendency to be solidified with continuous reflection.

Constructivist theory and teaching science in the social context are a main stream in science education. This study was purposed to introduce the STS in-service program implementing in Chonnam National University. and to analyze the results of the program in terms of changes of teachers' and students' perceptions and attitudes. The major features of the STS in-service program were as follows: teacher-centered. teaching in the social context. emphasis on constructivist approach. development of STS module and implementations. A total of 20 secondary science teachers participated in the in-service program. and filled out two questionnaires. Science Education Reform Inventory and Constructivist Teachings Survey. Three of the 20 teachers were selected to gain information from their implementations of a STS module into their respective classrooms. The students completed two instruments. Constructivist Learning Environment Survey. and Scientific Attitude Survey. The responses from teachers and students are as follows: 1. The participating teachers were very aware of the necessity of reform in science education. and the degree of the perception of the necessity increased after the STS in-service program. 2. The STS program significantly improved constructivist teaching techniques. 3. The perceptions of the students about constructivist learning environments improved significantly after the STS in-service program. 4. Students' scientific attitudes improved significantly through STS approach. The STS in-service program with the above mentioned features was found to be effective in our current school system. and could be implemented successfully if teachers were willing to learn and participate in the reforms of science education.

In this study, a questionnaires survey was administered to Korean and Japanese junior high school science teachers in the capital area to investigate the extents of Science-Technology-Society(STS) education practiced in science classroom. The responses of 69 Korean teachers and 33 Japanese teachers were analysed. The results showed that most of teachers in both country knew well about the meaning and the purpose of STS education. Also they realized the needs of applying the STS education in science class and had wills to do it. However, only about a half of teachers - more than a half of Japanese and less than a half of Korean - were practicing the STS related subjects, activities and assessments in the class. Teachers in both country responded that their science textbooks did not contain enough amounts of STS related contents and other STS education materials available were not much. Therefore, it is needed to include more STS related contents in the science textbooks and to develop various STS education materials and circulate them as well as to establish adequate teaching and assessment methods for STS education. Also activating teachers' meetings to circulate the informations and materials and improving the school environments are recommended.

Prospective high school students and science teachers' perceptions of 'advanced material', which was first introduced in the science textbooks of the 2009 revised curriculum, were surveyed. One thousand four hundred and ninety nine students and 123 teachers from Seoul, Incheon, and the Kyeonggi areas participated in this survey. The results are as follows. First, the attitude of students and teachers towards 'advanced material' was positive, but their interests in 'advanced material' was low. Also, some teachers mentioned that 'advanced material' was one of the difficult subjects to teach. Second, the perception of 'advanced material' was relatively low for both students and teachers. Both of them had heard of 'advanced material' through various routes, however not many of them thought that they knew what 'advanced material' was exactly. Also there were some teachers who didn't understand the detailed information of 'advanced material'. Third, both students and teachers agreed that 'advanced material' was worthwhile to learn and teach. However, each party had their own desire of 'what to learn', 'what to teach', 'how to learn' and 'how to teach'. Based on the results, some suggestions were made for effective teaching of this new subject.

Despite the growing importance of socio-scientific issues (SSI), little work has focused on teachers' pedagogical knowledge, and few studies have examined how in-service teachers use and apply SSI-related instructional methods and strategies. Consequently, the purpose of this study was to explore how science teachers with lots of SSI teaching experience determined teaching orientation, selected and revised instructional methods, and devised assessments in science classroom. We used a case study approach aimed at a deep description of these teachers' teaching experiences and employed semi-structured and in-depth interviews with five experienced teachers. Our findings indicate that teaching orientation and learning objectives seemed to influence the selection and modification of instructional strategies and methods. In addition, students' learning experiences or classroom environment were considered and modified in light of achieving these learning objectives. However, introducing SSI into the classroom assessment is not seriously considered by most teachers. This study can provide teachers with useful information when designing and developing SSI classes, taking into account various aspects of the PCK such as learning orientation, instructional methods, learner expereince and curriculum standards.

This study intended to find evidence of changes in teacher beliefs of teaching and learning and a case of infusing research experiences in teaching modules since their research participation. As part of this study, twenty three science and math teachers in Korea were provided with science research labs and field experiences in the University of Iowa for three weeks. The research units that teachers participated in for three weeks covered seven fields of subjects such as: geology, astronomy, chemistry, physics, mathematics, computer science, and environmental engineering. In the course of this study, the effectiveness of science research participation program was explored in terms of changing teacher beliefs and their production of teaching modules based on their research. This study especially focused on identifying changes of beliefs on science teaching and learning after participating in the research. A case study of a participant teacher was also conducted by comparing descriptively teaching modules before and after experiencing the program. It was found that the program affected the new modules and the research experiences affected participants' beliefs toward student centeredness.

Many science teaching models have been devised and published for the students' conceptual change by researchers. However, the science teachers have been confused with so many models to be used in teaching science. Since the models are composed of ambiguous statements, it seems to be difficult for the teachers to understand their characteristics and natures. Therefore, the models were difficult to be adopted in science instructions. In this study, the researcher developed two checklists which were devised especially for the teachers who apply the Cognitive Conflict Process Model (the Procedural Teaching Model using Cognitive Conflict Strategy) in Science Concept Instruction. One is for planning instructions using the model, the other is for examining or analysing them. Each of them consisted of 20 items and 33 items, respectively. Using these checklists, the Cognitive Conflict Process Model can be checked whether it was applied properly in actual instruction or not.
