The purpose of this study is to explore the variables of knowledge, acceptance of theory of evolution and epistemology that could be keys for teaching and learning the theory of evolution within school contexts, and to suggest instructional tips for teaching evolution in relation to the grade levels of education. This cross-sectional study examined the grade level differences (8th, 11th, and preservice teachers) of four variables: evolutionary knowledge; acceptance of theory of evolution; and both domain-specific epistemology (nature of science in relation to evolution) and context-specific epistemology (scientific epistemological views) and their relationships. This study, then, built conceptual models of each grade level students' acceptance of theory of evolution among the factors of evolutionary knowledge and epistemology (both domain-specific and context-specific). The results showed that the scores of evolutionary knowledge, evolution in relation to NOS, and scientific epistemology increased as the grade levels of education go up(p<.05) except the scores of acceptance of theory of evolution(p>.05). In addition, the 8th graders' and the 11th graders' acceptance of evolutionary theory was most explained by 'evolution in relation to NOS', while the preservice teachers' acceptance of evolutionary theory was most explained by evolutionary knowledge. Interestingly, 'scientific epistemological views' were only included for the 8th graders, while evolutionary knowledge and 'evolution in relation to NOS' (context-specific epistemology) were included in explaining all the level of students' acceptance of evolutionary theory. This study implicated that when teaching and learning of the theory of evolution in school contexts, knowledge, acceptance of evolutionary theory and epistemology could be considered appropriately for the different grade levels of students.

As science programs emphasize an understanding of the nature of science, it is needed to assess students' views on a wide range of science-technology-society topics. The purpose of this study is to investigate the views of high school students about some selected topics of the epistemology of science. The selected topics include the meaning of science, scientific assumptions, values in science, conceptual inventions in science, scientific method, consensus making in science, and characteristics of the knowledge produced in science. Identified preconceptions in the study are as follows: Science was seen as improving the world(20%), and technology was defined as the application of science(35%). Almost half of the sample(49%) subscribed to a view consistent with a creationist posture and large group of students(46%) expressed a purely ontological view. Only minority of the students(5%) discounted the role played by private science values, but one half of the sample denied the fact that gender-related values can influence the knowledge that scientist construct(53%). Only a small potion of the sample(5%) held a view contrasting to contemporary epistemology of science, but the majority(67%) expressed a simplistic hierarchical relationship in which hypotheses become theories and theories become laws. One third of the students(33%) held a preconception that the scientific method composed of questioning, hypothesizing, collecting data, and concluding. Students did not appreciate the role of consensus making in science(33%). An out-dated epistemic perspective describes the progress of science as simply an accumulation of knowledge(4%). In general, it was concluded that most high school students did not hold efficient understanding on the nature of science. It can be said that no adequate and consistent instruction took place to provide students with an authentic view of the nature of science.

이 연구의 목적은 경기도 소재의 한 과학관 전시 설명에 반영된 과학의 인식론적 특징을 탐색하는 것이다. 과학의 인식론적 이해는 오랜 시간 다양한 경험을 통해 형성되는 암묵적 차원이 크기 때문에, 학교 밖의 일상 경험을 통해 학생들은 다소 안정된 과학의 이미지를 형성하게 될 가능성이 크다. 따라서 본 연구의 대상은 학교 밖 과학교육 맥락의 하나인 과학관의 전시 설명으로 정하고, Ryder 등(1999)의 인식론적 범주를 사용하여 분석하였다. 연구의 결과는 '근거와 지식주장의 관계', '과학적 탐구의 본질', '과학의 사회적 차원'의 범주로 나누어, 각 범주에 대한 인식론적 특징을 세부적으로 탐색하고 해당 범주의 전시 설명 사례를 제시하였다. 전시 설명 사례는 주로 한 범주의 인식론적 특징을 반영하는 것으로 나타났다. 하나의 근거와 하나의 지식주장을 연결하거나, 개인적 흥미 혹은 과학 학문내적 탐구를 통해 지식을 생성하는 과정을 기술하거나, 과학 공동체 혹은 기관 차원의 과학 활동을 소개하는 등이었다. 본 연구의 결과를 토대로, 과학관 전시물의 여러 매체를 활용하여 다양한 범위의 인식론적 특징을 반영할 것이 제안되었다.

The purpose of this study was to explore ecological concepts, epistemological reasoning and reasoning processes through constructing 'food web and food pyramid' in ecology. We conducted classes which involved a 'food web and food pyramid' for $6^{th}$ grade students. Each class is constructed of small groups to do modeling and epistemological reasoning through communication. The researcher had videotaped and recorded each class and have made transcription about classes. We analysed patterns of 'food web and food pyramid models' and reasoning processes according to scientific epistemology using transcription data and student outputs. As a result, students represented phenomenon-based reasoning, relation-based reasoning and model-based reasoning in scientific epistemology from their modeling. Students usually did relation-based reasoning and model-based reasoning in food web which explains ecological phenonenon, while they usually did model-based reasoning in food pyramid which expects ecological phenomenon. Student's reasoning can be limited when they have misconception of scientific knowledge and are limited by fragmentary knowledge. This represents that students has to do relation-based reasoning and model-based reasoning is beneficial in their ecological model. It also suggests that students need to define correct-conception related to ecological modeling(food web, food pyramid).

사회현상은 복잡한 변수들에 의해서 변화되고 있기 때문에 새로운 과학적 인식론과 방법론의 기초가 요구되며, 우리가 직면한 문제들을 분석하기 위해서는 패러다임 전환의 체계적 이해가 필요하다. 본 연구는 자연과학에서 발전시킨 카오스 이론을 제시하여 현대 사회의 비정상성을 논함으로써 카오스 패러다임의 중요성을 제안하였다. 카오스 이론은 정치, 경제, 그리고 사회학의 주제를 가로지르는 광범위하고 다양한 사회현상에도 적용된다. 사회과학 연구에서 카오스 이론을 유효적절하게 개발하고 응용한다면, 사회현상을 탐구하기 위한 방법론적 및 이론적 기초를 강화하기 위한 수단으로서 유용한 패러다임의 역할을 수행하게 될 것이다.

The purpose of this investigation was to examine and compare pre-service and in-service elementary school teachers' beliefs about Science-Technology-and Society (STS), particularly beliefs about the nature of science and technology, their interaction within society, and the epistemology of science. Large percentage of pre-service and in-service elementary school teachers were understood to perceive as follows : 1. they regarded the science as 〃Knowledge scheme aiming content'and technology as 'skill for solution of actual problems'. 2. they revealed themselves to perceive tat science/ technology influence our lives through new terms and ideas, that science/ technology is affected by governmental policies and that all the people concerned including scientist and technologist should participate in the course of decision making. 3. they perceived that scientist perform their studies by characteristic abilities and that the studies are affected by their religious viewpoint. Moreover, they were understood to perceive that scientific knowledge are constructed through social interaction. 4. they perceived that scientist discover and develop scientific laws by scientific methods such as verification and certification, and that those scientific laws could be changed later.

Science teachers' beliefs about science and school science and their perceptions of the science laboratory learning environment were investigated with an assumption that science laboratory teaching would be affected by science teachers' beliefs. Likert-scale questionnaires of BASSSQ and SLEI were used in this study. The major findings were as follows: 1. Science teachers showed inconsistent beliefs about science and school science. Their responses reflected a patch-like view of postmodern epistemology and objectivism They also showed somewhat different views about science and school science. It was found that science teachers had strong objectivist views about science in some parts. but they had moderate constructivist views about school science in other parts; 2. The mean scores of student cohesiveness, integration. and rule clarity on the actual version in SLEl were relatively high, but those of open-endedness and physical environment were very low; 3. There was no association between teachers' beliefs about science and their perceptions of the science laboratory learning environment. But some associations were found between teachers' beliefs about school science and their perception on student cohesiveness, integration, and rule clarity of the actual science laboratory learning environment. Teachers' beliefs about school science had some statistically significant correlations with their perceptions on all scales of the preferred version of SLEI. We could not show a causal relationship between teachers' beliefs and their science laboratory learning environment through these results. But it can be suggested that teachers' beliefs about school science do have a role in constructing a desirable science laboratory learning environment, as we found that there were statistically significant correlations between them.

Prior research has reported that student epistemological beliefs might affect their participation in learning and the process of conceptual change. The purposes of this study were to investigate the characteristics of sixth grade students epistemological beliefs about science and the relation between their epistemological beliefs about science and factors related their learning. For this research questions, 245 sixth grade students participated and various test instruments were used in this study. Students answered two types of questionnaires on epistemological beliefs about science and three test instruments on factors related students' learning(achievement in science, science inquiry skills, and cognitive levels). The results of this study were as follows. First, a large number of elementary school students believed that the purpose of science to perform activities like simple experiments. A lot of students believed that scientific knowledge was changeable according to the nature of scientific knowledge and that scientific knowledge could be learnt on their own. Also, many students believed experiment results to be basis on which to form personal scientific conceptions. Second, students who believed in more modern epistemology about science represented higher levels of science learning achievement, science inquiry skills, and cognitive levels. Therefore, when developing science curriculum, science educators need to consider how to develop student modern epistemological beliefs about science.
