This study intends to delineate the characteristics of various perspectives on the nature of science (NOS) through the textbook analysis. Thus, centering on a science textbook called Science Laboratory Experiments, this study analyzes the elements of the NOS from three different perspectives: the consensus view, features of science (FOS), and family resemblance approach (FRA). While the consensus view highlights the similar elements of the NOS across the topics, the FOS is concerned about empirical ways for doing science. The FRA rather focuses on socio-cultural aspects of science activities. While the consensus view is useful to reify the features of the NOS, the FRA helps to understand science from various viewpoints. Regarding the philosophical account for three perspectives, all of them are ambiguous to some extent. The consensus view holds contradictory dispositions e.g., relativism vs. (post-)positivism, and critical realism and instrumentalism. The FOS supports empirical tradition but cannot effectively cope with the anomalous situation. The FRA is useful to show up the ways of science in both microscopic (personal) and macroscopic (social) viewpoints. However, the broader concept about science may mislead understanding of the NOS. Consequently, this study provides some implication for improving the framework of the NOS and teaching the NOS in the classroom.

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.

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.

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.
