이 연구는 전국 초등학교의 영재학급이나 지역교육청 영재교육 센터에서 영재학생들을 대상으로 현재 가르치고 있거나 과거에 가르친 경험이 있는 교사 122명을 대상으로 과학의 본성에 대한 인식과 본성에 대한 교수 태도를 알아보기 위한 것이다. 이 연구에는 Chen(2006)이 개발한 VOSE 검사지가 이용되었다. 과학의 본성에 대한 인식은 7개 영역으로 나누어 조사되었으며, 과학의 본성에 대한 교수태도에 대한 것은 5개 영역별로 조사하였다. 조사한 자료를 분석한 결과, 첫째, 과학의 본성에 대해 과학영재 지도교사들은 대체적으로 바르게 인식하고 있었다. 둘째, 과학의 본성에 대한 교수태도 측면에서는 과학영재 지도교사들은 과학의 본성에 대해 가르치고자하는 긍정적인 태도를 지니고 있음을 확인하였다. 셋째, 과학영재 지도교사들이 인식하고 있는 과학의 본성에 대한 인식 정도와 교수태도는 높은 상관을 보이지 않았다. 이러한 결과는 교사의 과학의 본성에 대한 신념이 교수학습과정에 반영되지 않을 수도 있다는 개연성을 보여주는 결과라고 할 수 있다. 이러한 결과는 교사의 과학의 본성에 대한 바른 인식뿐만 아니라 과학의 본성에 대한 교수 전략 연구가 병행되어야 함을 시사해준다.

Twenty years ago, the American Journal of Epidemiology published David Sackett's brief description of. clinical epidemiology and its practitioners [1]. This commentary was a useful focal point for an emerging discipline. By 1983, with clinical epidemiology already thriving in many academic medical centres, Walter Holland called into question both the term, 'clinical epidemiology', and the nature of the discipline [2]. More recently, clinical epidemiology has drawn strong criticism from John Last, a noted academician whose contributions include the editorship of the Maxcy-Rosenau Textbook of Public Health. Writing in the Journal of Public Health Policy in 1988 [3], Last referred to the 'uncritical enthusiasm' for clinical epidemiology in medical schools as 'a danger to health', and staked. a claim to the term 'epidemiology' as appropriate only to the description of what classical or population epidemiologists do. Faced with such views, practitioners and proponents of clinical epidemiology can respond in three ways. They can ignore the criticism, and go on about their business. They can reaffirm their differences and resort to defensive rhetoric. Or, the critique can become an opportunity for reflection about the nature of clinical epidemiology and its relations with sister disciplines in modem medical schools. The latter course is followed here by four physicians who-despite diverse backgrounds and interests-all consider their work to be in the field of clinical epidemiology.

Science education has been in a state of crisis for some time. To understand the science teacher's role, it is helpful to reconsider an aspect as fundamental as the nature of science. Since teaching cannot be separated from learning and knowledge, their very close dynamic processes need to prescribe the role of the teacher and student simultaneously. However, traditional views are limited because they tend to emphasize some particular selected aspect of learning and teaching. This paper investigates the epistemology of Michael Polanyi (1891 1976), which is often considered to transcend the confrontation between objectivity and subjectivity of knowledge. Polanyi reconceptualized science knowledge as 'personal knowledge' based on his own experience as a scientist and a thinker. In this study, I discuss 1) the nature of science in light of Polanyi's epistemology, 2) what this says about the meaning of science learning and teaching, 3) the potential of these ideas for the role of the science teacher.

이 연구에서는 과학사를 이용한 소집단 토론 수업이 학생들의 과학의 본성에 대한 이해, 학업 성취도, 과학 수업에 대한 즐거움, 과학 학습 동기에 미치는 효과를 조사했다. 연구 대상은 서울시에 소재한 중학교 3학년 학생 138명이며, 학생들은 전통적 수업 집단과 과학의 본성 수업 집단으로 무선 배치되었다. 처치 집단의 학생들은 과학의 본성에 대한 서로 다른 두 입장을 제시받았으며, 이를 바탕으로 소집단 토론을 실시했다. 처치는 5차시 동안 이루어졌다. 사전 검사에서는 처치 집단과 통제 집단 사이에 과학의 본성에 대한 견해 차이가 나타나지 않았으나, 사후 검사에서 처치 집단의 학생들이 과학의 본성에 대해 보다 적절한 이해를 나타내었다. 과학 수업에 대한 즐거움과 과학 학습 동기 검사에서도 처치 집단의 평균이 통제 집단에 비해 유의미하게 높았다. 그러나 학업 성취도에서는 집단 간에 유의미한 차이가 나타나지 않았다.

이 연구는 원자모형 사례를 이용한 과학의 본성 검사지를 사용하여 중등예비 과학교사들이 가지고 있는 과학의 본성에 대한 인식이 '원자모형'이라는 과학지식과 관련되어 어떻게 드러나는지를 살펴보고, 기존의 선행연구와 비교해 보았다. '모형에 관한 인식', '과학지식의 잠정성', '과학에서의 주관성', '추론과 상상력의 사용', '보편적인 과학적 방법에 대한 잘못된 신념', '과학과 예술의 비교'라는 6 관점을 조사하였다. 연구결과, 예비과학교사들은 과학지식(구름원자모형)의 잠정성, 과학에서의 주관성(톰슨과 러더퍼드의 알파입자 산란실험에 대한 해석)에 대해 비교적 잘 이해하고 있는 것으로 나타난 반면, 보편적인 과학적 방법과 관련하여 가장 바람직하지 못한 인식을 드러냈다. 모형(원자모형)에 관한 인식과 과학(보어의 원자모형)과 예술(피카소의 작품)을 비교하는 영역에서는 존재론적 관점과 구성주의적 관점이 혼재되어 나타났으며, 과학연구에서 상상력의 사용은 필수적인 동시에 최대한 자제되어야 한다는 다소 모순된 생각을 보여줬다. '모형'이나 '과학이론'과 같은 일반적인 용어를 사용하여 조사된 기존의 선행연구들을 본 연구결과와 비교한 결과, 과학지식의 잠정성에 대해 보다 높은 긍정을 나타내게 했으며, 과학자의 연구방법에 대해 구체적인 과학자를 제시하였을 때, 응답자들은 좀 더 바람직한 인식을 드러내는 경향을 보였다.

Natural Medicine is a medical system that tries to find the cause and cure of the disease in the nature emphasizing on natural healing power of human body. The most important value of traditional medicine in east Asia lies on the fact that this medicine is a medical culture and natural medicine that was selected by instinct and human nature reflecting the best possible remedy by the wisdom of evolution, and views the living phenomenon based on relation and circulation. This medicine is a natural medicine that tries to recover and promote the natural healing power by vitality and is a system that cumulates various empirical information about unique and complicated life phenomenon as a legacy of evolution in the body and the disease. The understanding of variation and adaptation of human species should be based on thorough knowledge of origin, instinct and nature of human as well as knowledge of survival and adaptation of human and environment based on evolution. And through this insight, the prevention and treatment of modern diseases should be developed. In this regards, traditional medicine in east Asia should be highlighted again as a study on adaptation and harmony of penetrating the cultural history of mind which has led the history of biological body and change of society and culture, and the repository of practical wisdom and knowledge.

최근 유수 과학교육연구자들은 세계 여러 나라의 과학교육 현장은 물론, 과학교육 연구 전통에서 과학의 본성 교육의 중심축을 형성해 온 '합의 과학의 본성 관점'에 대한 비판과 옹호 및 대안적 견해들을 갑론을박 형세로 제기하고 있다. 합의 과학의 본성 관점은 다각적인 경로를 통해 NOS 교육 표준화를 위해 구축한 '보편적 과학 지식의 본성'에 해당한다. 그 교의에는 과학 지식의 잠정성, 주관성, 이론 의존성, 법칙과 이론, 관찰과 추론, 상상력과 창의성, 사회문화적 착근성 주제 등이 포함되며, 몇 가지 선언적 문장으로 구성된 리스트 형식을 취하고 있다. 본 연구자는 지금까지의 서구 과학교육 연구 내 NOS 개념화 전통은 물론, 현 시점에서 논의되는 NOS 교육의 동향을 파악하는 것이 현대적이며 미래 지향적 과학적 소양인 교육을 위해 필수적이라고 판단하였다. 이에 먼저 문헌 연구를 통해, 특히 과학에 대한 전체론적 인식론을 주창해 온 저명 과학교육 연구자들이 제시한 합의 NOS 관점에 대한 논쟁과 비판의 요지를 파악하여 제시하였다. 이어 과학의 본성이 갖는 본유적 가치는 다양한 학문적 렌즈를 통해 과학이 기능하는 실제 방식을 표현하는데 있으므로, 그러한 기능을 충분히 수행하도록 이끌 수 있는 과학의 본성 개념에 다가가기 위해, 여러 대안적 과학의 본성의 내용 요소에 대한 제안 및 과학의 본성 교육에 대한 의견들을 살펴 보았다. 즉 '과학의 본성 개념이 갖는 논쟁적 요소에 대한 교수', '비판적 과학의 본성', '비판적 사고력 과학의 본성', '전체 과학', '과학의 특성', '재개념화 된 가족유사성 접근 과학의 본성' 등을 고찰하여, 현대적 과학철학과 과학지식사회학에 기반을 두어 과학의 본성 내용 지식의 보편성과 다원성을 중심으로 그 함의를 제시하였다.

This study started from the need to change the technocentric view of environment into the ecocentric one to overcome ecological crisis today. Thus, the purposes of this study are to reorganize characteristics of ecocentrism, to analyze ecocentrism of Native North Americans as a realistic model, and to finally find suggestions to environmental education. The results of this study can be summarized as follows; Frist, the ecocentric perception on relationship between human beings and nature pursues co-existence through harmony and balance based on holistic understandings. And the ecocentric perception on relationship among human beings attempts to preserve environment by overcoming rule structure among them. The ecocentric perception on relationship between human beings and spirituality is to set life goals to achieve spirituality rather than to pursue material life. Second, Native North Americans have a holistic world view that human beings and nature are an inseparable one through the symbol of 'the Sacred Circle'. They also lived simple lives which satisfies vital needs instead of pursuing material lives in terms of the perception on relationship among human beings. When it comes to the perception on relationship between human beings and spirituality, they feel sacredness from all things in daily life and want to have peaceful relationships with their own inside through spirituality toward 'Mother Earth'. Third, the ecocentrism of Native North Americans make suggestions that environmental education confirm again what roles of human beings are in ecosystem, and that it helps students develop ecological sensitivity by giving them many opportunities to go to field trips. Furthermore, environmental education helps them positively think about and actively choose simple life. In addition, it has to be designed to help students seek sacredness in daily life through ecological imagination. This study has values of newly organizing characteristics of each ecocentric idea by integrating it from complementary aspects, and pursuing direction of ecocentrism and its realistic possibility by analyzing the ecocentrism of Native North Americans as a model of ecological life.

An alternative vision for science inquiry that appears to be important and challenging is model-based inquiry in which students generate, evaluate and revise their explanatory model. Pre-service teachers should be given opportunities to develop and use their mechanistic explanatory models in order to participate in the practice of science and to have a sound understanding of science. With this view, this study described a case of pre-service elementary teachers' scientific modeling in magnetism. The aims of this study were to explore difficulties preservice elementary teachers encountered while they engaged in a model-based inquiry, and to examine how their understandings of the nature of scientific models changed after the model-based inquiry. The data analysis revealed that the pre-service teachers had difficulties in drawing and writing their own thinking because they had little experience of expressing their own science ideas. When asked to predict what would happen, they could not understand what it meant to make a prediction "based on their model". They did not know how to use or consider their model in making a prediction. At the end of the model-based inquiry they reached a final consensus of a best model. However, they were very anxious about whether the model was the "correct" answer. With respect to the nature of scientific models, almost all of the pre-service teachers initially viewed models only as a communication tool among scientists or students and teachers to help understand others' ideas. After the model-based inquiry, however, many of them understood that they could create, test, and revise their "own" models "by themselves". They also realized the key aspects of scientific models that a model can be changed as evidence is accumulated and a model is a knowledge production tool as well as a communication tool. The results indicated that pre-service elementary teachers' understandings of the nature of scientific models and their previous school science experiences could affect their performance on a model-based inquiry, and their experience of scientific modeling could help them enhance their understandings of the nature of scientific models.

Protected area based ecotourism is now the most interesting topic to the nature lover and policy maker throughout the world because of its linkage with economic benefits, protected area management and biodiversity conservation. Based on this premise our study explores the visitors' perception on the recreational potential of Kaptai National park and its potentiality in ecotourism development in Bangladesh. The field survey was carried out both in holidays and non-holidays of the week from the late winter season in 2009 to the spring season in 2010. A total of 118 visitors were interviewed with the help of a semi-structured questionnaire. Study findings revealed that about 62% male constitute the visitors group with the maximum number of visitors in the age of between 15-25 years (35.59%). The tourists were very much attracted by boat riding (93.22%) followed by scenic beauty of Rampahar-Sitapahar (85.59%). A major portion of about 57.14% tourists wished to visit the park within a year because they got a lot of pleasure from Natural and green environment (86.44%) followed by boating on Kaptai Lake (85.59%). Most of the visitors (36%) were happy about existing facilities but defined some problems such as tour guiding facility, food and drinking water supply, etc. About 71% and 66% respondents perceived that Kaptai National Park made them to be concerned and protective of nature and supports and sustains local ecosystem respectively and 43% respondents agreed that Kaptai National Park ensures the social equity and involve local people in ecotourism which are the most important elements of sustainable ecotourism. The present study results also predict that the park might be a good recreational area for enjoying with family members and group of friends through proper management and promoting the relationships among tourism, local people and biodiversity conservation.
