The purposes of this study can divided into three parts: First, to investigate high school science teachers' understanding concerning geologic time; second, to analyze contents related to geologic time in the secondary school science textbooks and teachers' guidebooks; and third, to compare the response type of science teachers using the results of the contents. Forty high school science teachers in the Chungbuk province are chosen to answer to the questionnaire. Many teachers (50%) think that the age of Earth is simply measured by radioisotope. However, most of them do not know the measuring method in detail. The over 50% of the teachers think that the uniformitarianism, law of superposition, law of faunal succession law of unconformity, and law of intrusion are the great five laws of historical geology. Many part of the contents related to geologic time in the textbooks and guidebooks are incorrect and described distinctly from each other. Such content includes the age of Earth, age of the oldest rock in Earth, definition and range of geologic time, measuring method of the Earth's age, and law of historical geology. Many of the science teachers do not have a complete understanding of the contents related to geologic time. This study suggests that the reason lies heavily on the contents described in the textbooks and guidebooks. Therefore, it is necessary to review and revise the contents related to geologic time in the textbooks and guidebooks.

The purpose of this study is to examine the pedagogical content knowledge (PCK) elements and the changes in the science lesson planning and implementation difficulties experienced by high-career elementary school teachers with over 20 years of educational experience through the instructional consulting case of the Seoul City Office of Education Scholarship Support Group in order to find implications on effective instructional consulting support plan for improving the science teaching professionalism of high-career elementary school teachers. The result of this study is as follows : First, the pedagogical content knowledge (PCK) elements on the science lesson planning and implementation difficulties experienced by high-career elementary school teachers with over 20 years of educational experience were related to teaching strategy and they experienced difficulties in lesson content organization using lesson model and experiment facilitation and questioning, as well as in the area of interest and motive management that are definitional characteristic of learner in the learner element. Second, as for the changes in the PCK through science instructional consulting, they recognized the importance of the designing and experimenting process as students become the subject in the experiment facilitation in lesson, and they ended up attempting the postscript for promoting the thinking power of students. In addition, it was found that not only the cognitive characteristic but also the definitional characteristic of learner is important in science lesson and that students' motive is also an element that needs to be continuously managed. Third, as for effective instructional consulting plan for enhancing the science teaching professionalism of high-career elementary school teachers, it was revealed that it is necessary to first develop lesson expertise improvement consulting program that takes into account of teaching profession advancement phase of high-career teachers, and establish instructional consulting system and human resource pool of high-quality consultants based on the administrative and financial support from the Office of Education. The academic significance of this study is in the fact that it examined and searched for support plan on science teaching professionalism of high-career elementary school teacher, but a more extensive and in-depth study is needed since there is a limitation in this study on the object of study and the period.
Purpose: The purpose of this study was to identify needs of health education of the students, parents, general teachers, and health teacher of the elementary, middle, and high schools. Method: 279 schools of elementary, middle, and high school were sampled nonproportionally during the period from June 28 to July 26, 2004 The data were collected by the questionnaire from 1,888 students, 1,876 parents, 1,695 general teachers, 279 health teachers. A frequency, % and $x^2-test$ were used to analysis by SAS program. Result: 1. It showed that 98.1% of elementary school students, 92.3% of middle school students, 89.6% of high school students answered that they need health education. The most of students, parents, and general teachers had high interests in health education. 2. In the case of students, main causes of needs of health education was 'to prevent diseases or accidents'. But parents answered that it was 'to build up a healthier behavior'. General teachers answered that it was 'more effective systematic and continuous health education'. 3. Over 80% of students, parents, and general teachers about the question of who qualified person is to teach health education as a regular class responded that health teacher is available. Especially 93% of elementary school students answered like that. 4. The most of students, parents, and general teachers answered that health education in the classroom is favorable 1 to 2 hours per week. Conclusion: As results of the study, the majority of students, parents, general teachers agreed needs of health education. Therefore, on the basis of this study, systematic and continuous health education is necessary. Additionally the establishment of independent health subject is required certainly.
To meet the objectives of environmental education, teachers especially have to perceive the importance of environmental education, comprehend various characteristics of teaching/learning methods, and be able to conduct classes by choosing proper teaching/leaming methods in accordance with a specific purpose and educational focus about environmental education. Therefore, it Bs necessary to investigate the current status of Korean environmental education and provide teachers with appropriate environmental teaching/leaming methods. To this end this study aims to examine Korean science teachers'perceptions'on environmental education and the kind of teaching/learning methods which can be utilized in environmental education. Teachers who completed the survey were 135 science teachers from middle and high schools in Seoul, and 126 social science teachers from Kyoungki province. The majors of the science teachers were in physics, chemistry, biology, geology, and earth science. Also, there was one teacher who majored in special education. For social science teachers two majors were common, geography and general sociology. After analysis of the data from the surveys the results are as follows. First, science and social science teachers in middle and high school recognized the necessity of environmental education in school education. Second, most teachers had applied environment related topics to their subject of study occasionally, but they mostly concurred that environment related contents should be included in their textbooks. Third, science teachers agreed that field trip, discussion, and the STS approach were the most proper methods for environmental education, and social science teachers agreed that field trips, inquiry, and discussion were the most appropriate methods for a teaching environment. They realized that they should decide good teaching-learning methods appropriate to the objectives and content needed for effective environmental education as they selected different teaching-learning methods according to detailed environmental objectives and contents in their textbooks.

Various modern social problems are also related with science and technology. Thorough understanding about Technology-Society(STS) interactions is required to take informed action about how to deal effectively with these problems. In this case, there is a need for STS education. The purpose of this study was to examine the perceptions of high -school students and science teachers about Technology-Society interactions and differences of their perceptions. It is my hope that this thesis will contribute to future "General Science" class in Korea. We obtained the data by a survey of 414 high school students who took "General Science" courses in Seoul and 54 of their science teachers. The survey was made using 10 multiple-choice items selected from the VOSTS (Views On Science-Technology-Society) item pool. The results of this study are as follow: 1. More than half of the students and teachers thought that science is exploring the unknown and discovering new things. Their perceptions about the science are somewhat stable, but about the technology various. 2. Most students and teachers thought that science and technology interact and complement each other. They also thought that the improvement in the quality of life needs investments in both science and technology 3. Most students and teachers thought social facts as community, government, and politics influenced scientists and scientific research. They also had a good understanding about the effects of science and technology on society. We can conclude from this that they had a Science-Technology-Society oriented viewpoint. 4. There are significant differences between the perceptions of boys and girls in following categories (p<.05): Influence of Community or Government Agencies on Scientists Influence of Politics on Scientists Role of Scieoce/Technology in Resolving Social Problems 5. There are significant differences between the perceptions of students and teachers in following categories (p<.05): Definition of Science Influence of Politics on Scientists

As part of the second-year monitoring study on the implementation of the 2015 revised science curriculum, this study investigated high school science teachers' perception and realization of instruction and assessment of elective courses to derive measures to settle and improve the science curriculum. A total of 244 high school science teachers responded to the survey questionnaire, and 9 teachers participated in interviews. In survey results, science teachers are contemplating ways to increase students' science competencies and their participation in classes, but still, lecture-oriented classes are most often used in their teaching. Regarding assessment, teachers responded that there were positive changes in all of the questions related to process-based assessment (PBA). Regarding the difficulty of managing science elective courses, teachers most often selected increased numbers of subjects being covered, overload of work, and the burden of restructuring classes considering various ways of teaching and assessment. Through in-depth interviews, teachers argued the difficulty for Science I courses to emphasize student participatory classes compared to integrated science, and the difficulty to implement student participatory classes for Science II courses, which are mainly placed in the third grade. Teachers also argue that it is necessary to secure time to implement PBA in science elective courses, and that there is no need to implement PBA for the science experiment since there are no tests on the SAT. Based on the results of the study, discussed in the conclusion are support plans for the settlement of PBA in elective courses, and the need for in-depth analysis of the direction and cause of student participatory classes and PBA at the school.
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.

The purpose of this study is to inquire the properties and relationship of attitudes toward science and process skills of preservice elementary teachers. Two instruments were used to collect the data, SAS(Science Attitude Scales) for checking up attitude toward science and TIPS II(Test of Integrated Process Skill II) for inspecting science process skills. Three main results were revealed. First, preservice elementary teachers' the attitude toward science and science process skills could not show the significant differences by gender. This result is differ from the results of preceding researches which had set up the students of elementary, middle and high school as objects. Second, the properties of preservice elementary teachers' the attitude toward science and science process skills according to the course in high school were also differ from those of preceding researches having students as objects. The preservice elementary teachers who got the literary courses in high school were more confident in science learning and perform that those who have the academic background of science courses in high school. In addition, although they showed better abilities in two sub-scales of science process skills, the preservice teachers with science course didn't show the better science process skills than those who had taken the literary course in total score of science process skill test. Third, there was a significant relationship between attitude toward science and science process skills of preservice elementary teachers but just one sub-scale was related with science process skills. According to these results, it can be said that the preceding results with students as objects can not be applied to and preservice elementary teachers should be guided by the methods which are considering their special properties.

The field is a good learning environment that offers many opportunities. Status of conducting field trip in the middle and high school was investigated As a result, there was few teachers who disagree that a course in science should include learning in the field. Yet, on practical side, teachers who used to conduct the field trip over once a year in science class appeared to be about 23% only. Most of schools conducting field trips hadn't well-planned program for instructional activities. Many of teachers appealed that they should not get release time for conducting an extended field experiences, and that they could not obtained good information in relation to the contents, the methods and strategies of field activities. It says that a good field trip needs administrative and financial surport, many informations, and the teacher's exertion.
