The purpose of this study is to explore their experience through teachers' interviews in research schools for the Education for Sustainable Development(ESD). The first issue for ESD in school was about how to approach ESD and how to combine it with the school curriculum. Of course, ESD can be approached through both subjects and discretion, which are operated with focus on experiential study. Most teachers approached ESD through subjects, but they had a lot of difficulties in its implementation because of insufficient understanding. The advantage of ESD programs is to provide students with an opportunity for experiential activity based on localization. However, difficult parts in applying ESD to school education were matters of budget for invitation of experts or for the experience learning as well as overworking of the teachers with conceptualization of ESD. Consequently, there has been change in the perception of teachers and students through ESD in schools, which have influence on the integrated thinking from diverse perspectives. Stories of research school teachers offered through categorization of interviews will provide a lot of help in the process of applying ESD to school education in the future.

Recently experimental class model is growingly recommended for mathematics instruction. Freudenthal(1973) points out the difficulties of learning probability and Fischebien suggested to teach probability more intuitively through games. However detailed explanations for such classes are not easy to find. This paper is to give more detailed materials for those lessons and to check its effectiveness. We give 6 topics of probability and statistics being taught in our middle school, such as histogram, concept of probability, probability calculations, expectations, standard deviations, and correlations and each of which is given along with the experimental materials to be used. We perform a trial of the methods and found some encouragement in the students' mathematical attitudes and interests but not in the achievements. We belive that the drawback of the achievement result is due to the short length of time of our experiments.

The purpose of this study is to make a list of scientific terms to decrease students' difficulties of science learning. By using inductive method, database has established from elementary school science textbooks and laboratory observation books. All terms from physics area of science textbooks and laboratory observation books at the levels of grade 3 to 6 were analyzed based on the Standard Korean Dictionary (1999) and Book of Physics Terminology (2005). As a result, we made a list of 204 scientific terms by grade level. Those were 51 words for grade 3, 55 words for grade 4, 56 words for grade 5, and 42 words for grade 6. And there were some incongruities among textbooks, the Standard Korean Dictionary and the Book of Physics Terminology.

지구과학 학습 내용들은 교실이나 실험실에서 통제하기 어려운 내용들이 많다. 따라서 이를 극복할 수 있는 하나의 방안으로 가상현실 기술을 도입하여 웹상에서 활용할 수 있는 3D 가상현실 학습프로그램을 개발하였다. 개발된 프로그램은 701명의 중학교 학생들에게 투입되었다. 그 결과 몰입감을 통한 흥미유발 및 동기유발에 아주 긍정적인 효과가 있었으며, 공간지각 능력 향상에도 큰 도움이 되는 것으로 보여졌다.

The current reform recommendations in the United States have been widely recognized but the outcomes with regard to the teaching practice in the classroom were evaluated as ineffective to faster students' mathematical learning. Given this, this paper reviews the current mathematics education reform in terms of the typical and the recommended teaching practices. An analysis of influences of theoretical perspectives is then provided as an attempt to explore the underpinnings that implicitly motivate the current reform movement. This paper then identifies the difficulties in implementing reform ideals. Building on the review and the analysis, this paper finally provides implications of re-conceptualizing mathematics instruction in the current reform era.

Recently, the number of students to choose to study in Australia has been increasing significantly. The purpose of this study is to examine how Korean primary school children perceive their own English language learning and cultural adaptation in Australia. A questionnaire survey was conducted with 34 Korean children aged 8-13 who were attending primary schools in Brisbane, Queensland. The study results show that they made diverse efforts to learn English language and culture in Australia, such as making English-speaking friends, watching TV/video/DVD, reading English books, and studying with a foreign tutor. Their English listening and writing abilities were thought to be improved most, followed by speaking, reading and cultural understanding after studying in Australia. The subjects were mostly satisfied with their study and life in Australia but they had difficulties with communicating in English, homesickness, foods, weather, insects, and discrimination. In particular, they had problems with understanding classes conducted all in English and participating in the classroom activities due to their low level of English ability and understanding of Australian classroom culture. The findings of this study have pedagogical implications for educators both in Australia and Korea.

developed by solving practical problems and gradually formalized and abstracted. But school mathematics seemed to stress the formalized and abstracted mathematics. The same is the case with calculus. In particular, it appeared extremely in teaching of calculus. It caused hindrance of learning and indeed, many students had difficulties in teaming of calculus. Therefore this study investigates the various approaches of calculus teaching and the history of calculus which include approaches by Archimedes, Galileo, Newton, Leibniz and Weierstrass etc. This may offer the implication for calculus teaching and we can find the alternative on the method of calculus teaching in historico-genetic principle. Finally we suggest the direction of calculus teaching from this perspective in tile concrete.

삼각형의 외심은 중학교 2학년에 처음 도입되는 논증기하의 부분에서 다루어진다. 증명을 통해 도형의 성질을 다루는 과정에 본질적으로 상당한 어려움이 내포되어 있긴 하나, 학생들 은 교과서에서 다루는 외심과 관련한 명제의 증명을 학습하는데 특히 많은 어려움을 겪는다. 따라서 본 연구에서는 우리나라 교과서에서 다루는 외심의 정의와 증명을 오랜기간 논증기 하의 교과서로 사용된 유클리드 원론 및 현행 미국 교과서의 방식과 비교함으로써 삼각형의 외심 지도에 관한 시사점을 끌어내고자 한다.

The goal of the textbooks of 2009 revised curriculum is to make customized lectures possible considering learning characteristics and understanding level of students. However, it is not easy to find a research result on sensed difficulty of the mathematics textbook, which is able to provide valuable information on the development of the diverse level textbooks. This research suggested criteria in analysing sensed difficulties of field teachers on the textbooks, and analysed sensory difficulty on the selective tracks textbooks based on 2007 revised mathematics curriculum using the criteria. The results of the analysis on 59 mathematics selective tracks textbooks show that all have average sensed difficulty. The criteria and research results are expected to provide valuable information in future mathematics textbook development.

This study investigated how elementary school teachers reconstruct science curriculum and how they perceive about their experiences. In-depth interviews were conducted with four elementary school teachers who had experience in restructuring science curriculum. Two distinct types of reconstruction were found; restructuring within the subject and integrating between subjects. The teachers who were restructuring science curriculum from personal needs usually substitute, delete, add some contents or activities and change the order of unit within science subject. In contrast, the teachers who were participating in research school usually integrated science with other subjects, developing a new unit or project. The latter recognized the need of teachers' reconstruction of science curriculum more strongly and the importance of teacher's voluntary learning community in implementing the reconstruction. Though they had some difficulties in identifying students' interests and level of understanding and lack of time, all teachers valued curriculum reconstruction by relating it to teacher professional development, identity as a teacher, and job consciousness.
