The purpose of this study was to develope the education program using multimedia for endocrine disruptor, and to examine the learning effects of it on high school students. The subjects were 70 tenth grade students in the academic high school located in Chungnam. With dividing them into two groups: the controlled group and the experimental one, lessons were executed respectively. Total average of achievement was significantly different between control and experimental groups. Using multimedia learning can be effective in improving in terms of knowledge achievement. Meaningful difference did appear from almost, but did not appear between using multimedia materials group and traditional approach to tuition classes. The most of experimental group students were interesting of the education program using multimedia, and thought that multimedia learning materials were helpful to understand the lesson about endocrine disruptor. And experimental group students were more active and positive in the lesson using multimedia than in the traditional ones. By providing students with the proper learning materials that go with their traits and preference, the educational environments that students can take part in the class more positively and actively should be provided.

This study was aimed at finding what effects pro-con discussion classes have on students' environmental decisions and set a series of research questions as follows. First, in a small group discussion, how a student's environmental decision is affected by opinions of other students in the same group. Second, what would be the relations between a students' personal factors including gender, environmental knowledge, attitude, and behavior and their decisions. A decisional experiment was applied to 185 students consisting of 2 girl classes and 4 boy classes of K highschool located in Kongju City, Chungnam. These students were taking 'Ecology and Environment' as one of the few general selective subjects once a week. Decision issue introduced to the experiment was regarding of constructing a wind power station on Baekdu Mountains which is protected by the law. This issue can be characterized as not conflict between conservation and development but conflict between two different types of environment friendly approaches that make students experience more difficult while making a decision. The results of this study an be summarized as follows. First, after taking the class introducing environmental issues and having a debate other students on the issue both within a small group or all classmates together, just less then 30% of the students changed their selections. Second, students were found to be affected by other students' opinion while making his or her own decision. Third, no relationship was found to be statistically considerable between students decisions and their personal factors except of their courses, liberal or science.

This study was aimed at developing and providing textbook writers with information and materials required to introduce forest education ideas and paradigm into primary, middle, and high school students, responding to establishment of the new national curriculum. Research methods included interview with school teachers, literature review on forest education and policy, analysis of writings and drawings of elementary school students. As a primary result, the study produced a framework that can be applied to analyze and understand how people think of and put a value on forest, consisting of 1) Resource-Economic Perspective, 2) Environmental-Ecological Perspective, 3) Cultural-Educational Perspective, and 4) Existential-Ethical Perspective. To test its validity, the developed framework was applied to the processes of reorganizing and interpreting the outcomes of teacher interview and writings and drawings of elementary school students. The results of applications showed that current school education mostly focused on ecological-environmental (about 50%) and cultural-educational (about 30%) perspectives on forest. To improve the quality of current forest education in schools, five main directions including integration, balance, interrelatedness, identity, and systematic approaches were suggested.

This study is to consider the fundamental perceptions of pre-service elementary school teachers to natural environments. The recognition items of questionnaire for those environments include ones of water, atmospheric, soil, biologic and oceanic environments constituting of the earth system. From the results of the study, they affirmatively recognized biologic environment, but they showed highly negative recognitions to others. In other side, it is considered that their recognitions to natural environments were probably transferred by the things which involve press media, curricula and real lives. On the basis of the study results, systematic teaching-learning for natural environments is essential because the encouragement of eco-friendly attitude, one of main goal for environmental education, is budded from basic understandings to natural environments. Affirmatively environmental worldviews for elementary school students are important for reasons why teacher's quality and practice will is fundamental, and then teacher could change the views of the students for environmental education. So, preparing balanced attitudes, right concepts and connection to applicable knowledges for natural environments, pre-service elementary school teachers in environmental education must be pointed to organized education between human and natural environment.

The purpose of Environmental subject in the Korean school is pretty much similar to that of international organization. Because it doesn't apply the characteristics of School Education to environmental education, this school environmental education purpose needs to be discussed. The purpose of this study is to establish the reasonable purpose of school environmental education by analyzing the educational views. This study have been done through review of research literature, which usually includes references and papers on environmental education, school environmental education, educational point of view, educational purpose. It analyzed three kinds of views on education: technological view on education, initiation view on education, socialization view on education. The results are as follows: The purpose of school environmental education from technological view on education is environmental education activity itself that educates students to put the environmental preservation value into action. Initiation view on education aims at school environmental education as activities that instruct students on intellectual ability in order to develop a comprehensive view of intelligence. The purpose of environmental education in school on the basis of socialization view on education focuses on activities that authoritative teachers transmit the social value of environmental preservation to students in school.

The purpose of this study is to analyze the status of new & renewable energy education in elementary school textbooks and to develop workbook related new & renewable energy education for elementary school students. The results of this study are as follows. First, in the result of contents analysis energy education and new & renewable energy education through textbooks on 7th elementary school curriculum, subjects including contents related energy are Disciplined Life, Intelligent Life, Moral Education, Social Studies, Science, and Practical Arts. Contents related new & renewable energy are taught $4{\sim}6th$ grades but the quantity and quality of contents are very poor. Second, this study developed workbook related new & renewable energy education for 5th and 6th grades. The workbook is organized with 5 themes that are the need of new & renewable energy, the definition and kinds of new & renewable energy, strengths and weakness of new & renewable energy development, a case of new & renewable energy, and the application of new & renewable energy to practical life. Third, to improve workbook developed, it was applied to 6th grade and then more appropriately modified. Based on the results, it suggests the following for new & renewable energy education. Energy education in elementary school must equally be taught through the all scope of energy education. To solve the energy problem, the content related new & renewable energy education should be included much more both quantity and quality. New & renewable energy education workbook developed in this study is expected to reinforce current textbooks that is being taught a little content of new & renewable energy education.

이 연구의 주요한 목적은 환경교육과 학생의 진로 발달을 고찰하는데 있으며, 구체적인 연구목적은 그들의 진로 전망 인식, 진로 준비 과정, 대학의 진로발달지원을 이해하는데 있다. 대부분의 대학생에게 학교를 다니는 주요한 목적은 진로를 준비하는 것이지만 대학의 교육은 그들이 원하는 직업을 얻기에 충분하지가 않다. 전공이 특정한 진로경로를 가지고 있지 않거나 또는 전공이 특정한 진로경로를 가지고 있지만 흡족하고 질 높은 직업을 제공하지 않을 때 진로 준비는 더 복잡해진다. 학부 환경교육과 프로그램이 최근의 전형적인 예이다. 학부 환경교육과 학생들과 그들을 둘러싼 환경을 이해하기 위해 2007년 8월 17일부터 8월 20일까지 인스턴트 메신저를 통해 항구대학교(가칭) 환경교육과 학부, 졸업생 6명에 대하여 반구조화된 인터뷰를 실시하였다. 인터뷰는 연구 참여자 한 사람 당 $1{\sim}2$회, 1회 2시간 정도 개별적으로 실시하였다. 연구의 결과는 다음과 같다. 첫째, 그들은 진로 전망, 진로 결정에 대한 긍정적인 태도를 가지고 있었지만 잘 발견되지는 않았다. 두 번째, 진로 탐색, 진로준비는 개인적으로 수행되며, 학교는 많은 체계적인 진로 지원을 제공하지 않고 있었다. 세 번째, 프로그램의 교과과정과 그들의 미래진로는 관련을 보이지 않았다. 이 연구의 결과로부터 대학에서 진로 발달과 관련된 몇 가지 주요한 함의가 도출되었다. 첫 번째, 환경교육과 프로그램의 학부 학생들은 전공과 관련된 직업 기회의 탐색으로부터 직업 탐색 스킬의 개발에 이르기까지의 종합적인 진로 발달 지원이 필요한 것으로 보인다. 특히 경험적인 진로 탐색이 환경교육이 자신의 적성과 흥미에 적합한지를 이해하는데 도움이 되는 것으로 보인다. 두 번째, 이들 학생들을 위한 진로 발달 지원은 대학교 저학년부터 실시해야 한다. 세 번째, 이들 학생들은 다른 학문적 영역뿐만 아니라 그들의 전공과 관련된 다양한 기회를 탐색하는 데 있어서 도움을 필요로 할 것이다.
