  • This study examined the changes of preservice biology teachers' NOS pedagogical content knowledge through two consecutive science methods courses: NOS understandings; attitudes toward teaching science; difficulties of NOS teaching; NOS teaching strategies; and views of orientation of NOS teaching. During the science methods course I, the preservice teachers engaged in discussions and reflections on what science is and how scientific knowledge has produced, drawing NOS aspects from episodes of history of science, and planning the lessons cooperating NOS instructional objectives. Then the next semester, through the science methods course II, the preservice teachers had a chance of the simulated teaching by adopting NOS teaching and learning activities in the context of the secondary biology context. The preservice teachers, further, reflected on their NOS teaching. The results showed that the preservice teachers constructed the NOS pedagogical content knowledge. They significantly improved their views of NOS and its teaching(p<.05) after the science methods course I, and retained their understanding after the science methods course II(p>.05). The preservice teachers mentioned the difficulties of teaching NOS in the secondary biology context, and further suggested effective NOS teaching methods in their reflective journals.

  • Citizens should be sensitive to the complex and controversial SSIs (Socioscientific Issues), be able to make a responsible decision with evidence and empathy, and furthermore take political action for the larger welfare. The premise of this research is that understanding the nature of science (NOS) takes an important role when students and adults participate in the discourse on SSIs because SSI reasoning requires individuals to examine information and counter-information with skepticism. We therefore designed SSI programs that were incorporated with NOS by adapting a contextualized-reflective approach. The leading research question was to what extent SSI contexts contributed to promoting students' understanding of NOS. A total of 71 11th grade students participated in this program. The school was located in an urban city near the capital city of Seoul, South Korea. We designed SSI programs to cover the issues of genetically modified organisms, climate change, and nuclear energy. Each issue required four to six class periods to complete. We conducted pre- and post-program tests using the revised VNOS-C, recorded group discussions or debates and collected student worksheets to observe the increase of student NOS understanding. As a result of this program, students showed moderate improvement in their understanding of NOS.

  • Nature of Science(NOS) has been a well-organized focus of science education and one of the key elements in defining and cultivating scientific literacy for more than a century. In recent years, a specific description of NOS, which is often known as 'the consensus view of NOS', has become very influential and has gained ready acceptance as an arrangement for both curriculum building and research into understanding of NOS by students and teachers in many countries around the world. This study has two purposes; one is to review some debates and criticism on the consensus view of NOS which consists of a list of sentences to describe nature of refined and general science, which have been heated up for the last few years by many prominent science education researchers, and the other is to consider alternative perspectives on NOS for the purpose of a new direction of NOS education. As a result of an investigation into such views as 'Teaching about NOS', 'Critical NOS', 'Critical Thinking-NOS', 'Whole Science', 'Features of Science' and 'Reconceptualized Family Resemblance Approach to NOS', some implications which focus on the generality and plurality of content knowledge of NOS based on current philosophy of science and sociology of scientific knowledge are suggested for the improvement of teaching and learning NOS.

  • Understanding of the nature of science (NOS) has been a consistent topic as one of the most important goals in science education for the past several decades. Even though there is a variety of research related with the NOS conducted in science education, few researches has been conducted for the conception of scientists regards to the nature of science (Bayir et al., 2014; Taylor et al., 2008; Wong & Hudson, 2008). Recently, researchers in science education turned their attention to identifying views of scientists about the nature of science since they recognized the importance of participation of scientists in science education (Southerland et al., 2003; Taylor et al., 2008). This study was conducted to examine the Korean scientists' views of the nature of science. Through the use of semi-structured questionnaire and in-depth interview the views of 35 scientists who belong to the Korean-American Scientists and Engineers Association (KSEA) regards to the nature of science were explored. Findings show that while the scientists have more informed views with respect to the tentativeness of scientific knowledge, cultural and social influence embedded in science, the limitation of science, and the collaboration of science with others, the scientists have more na${\ddot{i}}$ve views about the distinction between laws and theories, the existence of a universal scientific method, and the importance of imagination and creativity. As such, it can be assumed that the scientists cannot conceptualize their notion in a philosophical sense even though they are engaged in scientific work in reality (Bayir et al., 2014).

  • 이 연구의 목적은 인지적 전략인, 갈등도(Oh, 2011)를 기반으로 학생들이 명시적으로 과학의 본성(NOS)의 교육을 돕기 위하여 과학의 본성요소뿐만 아니라 과학의 역사를 담은 NOS Flow Map을 개발 제안하는 것이다. 예비적으로 과학의 본성의 교육을 위해 제안한 NOS Flow Map을 사용에 대한 이해를 탐색하기 위하여, 자신들의 NOS 이해를 강화하기 위해 우리가 제안한 NOS Flow Map의 유용성에 대한 예비 초등교사들의 인식를 조사하였다. 과학의 본성에 대한 중요한 관점들은 Kuhn의 과학철학과 역사가 아주 잘 일치된다. 즉 Kuhn의 과학혁명의 예로 가장 중요한 Copernicus의 혁명과정이 과학의 본성 중요한 요소들과 잘 일치됨을 보여준다. 따라서 이 연구에서 인지갈등을 통한 NOS 흐름도는 과학의 소양교육을 강화하는데 명시적이고 반성적인 도구이며 유망한 방법이라고 조심스럽게 제안한다.

  • In 21st century, it is essential to understand Nature of Science (NOS) related to science educational curriculum. The study analyzed Earth Science components of third- through sixth-grade science textbooks in terms of incorporated NOS themes and their relative proportions. Modified analysis methods of Chiappetta et al. (1991) and Lee (2012) are devised and adapted. The results of analysis indicates that the current elementary school textbooks include and explain all the four themes of NOS, but do not include sub-areas of each theme of NOS in a balanced way. In addition, the themes of NOS in Earth Science are not treated equally among different grades. Such results warrant the efforts to include balanced themes of NOS into elementary school science textbooks with the ultimate goal of fully and properly comprehending NOS to the students.

  • The purpose of this study is to identify the status of the science museum reflected in the exhibition, and develop and apply Nature of Science(NOS) education programs based on the science museum exhibition. The analyse tool was developed to understand the NOS in the science museum. The researchers recognized the nature of science reflected in four exhibition halls in Korea. Based on the analysis, we developed the NOS education program. NOS education programs were developed and applied to supplement the NOS that appears to be limited to scientific exhibitions based on the prior analysis of science exhibition. The results of the study were as follows. First, we analyzed the nature of science reflected in the exhibition of two main science museums, and it was mostly implicit and most were to understand the relationship among STS(Science-Technology-Society). And also we analyzed the NOS reflected in the exhibition of two national history museum, and it was also mostly implicit and most were about the way of how to find out the knowledge, inference. Second, in order to supplement the NOS of the science museum, we developed the NOS education program based on the exhibits. After applying it to the science museum, we conducted a qualitative study. As a result, there was a positive change only in the aspects of NOS (science is tentative, science is from creativity and imaginative, science is the produce of social and culture, science is from the scientific method) that reflected explicitly. The conclusions derived from this study are as follows : For the cultivation of science in the scientific museum, various factors are needed depending on the theme of the science museum. Also, it is helpful to actively implement the NOS educational programs that utilize the exhibit. Therefore, the exhibit planners' and developers' competencies are critical to develop explicit NOS education programs in its expertise.

  • In this study, 46 teaching materials for understanding the nature of science (NOS) were developed based on the 42 statements describing the NOS. Each teaching material involves scientific knowledge and scientific inquiry skills as well as NOS statements. Teaching materials consist of students' learning worksheets and teachers' guides. Among the materials, 11 materials for understanding the nature of scientific thinking (NOST) were applied to 3 scientifically gifted students. As results, the degree of difficulty was appropriate and students showed interests in scientific thinking rather than new concepts or inquiry activities involved in the materials. It was expected that understating the NOST would be helpful for conducting scientific inquiry in more authentic way. And similarly to the Park's (2007) theoretical discussions about the relationship between the NOS and scientific creativity, students actually responded that undertrading the NOST could help their creativity. Therefore, it was expected that teaching the NOST would be plausible elements for teaching scientific creativity.

  • This study aimed to investigate a perception of teachers engaged in special education for scientifically gifted regarding nature of science and identify attitudes toward teaching nature of science. The sample of this study consists of 122 science teachers who are teaching or taught students attending gifted classes of any primary school in Korea and any gifted education center of every District Office of Education. We made a partial amendment of a VOSE that was developed by Chen(2006) and then used. We tested their perception and attitudes in regard to nature of science. In terms of nature of science, we devide it into 7 sub-areas to analyse. For attitudes toward teaching nature of science, we investigate and analyse following 5 sub-areas; tentativeness of scientific knowledge, nature of observation, scientific methods, theories and laws and subjectivity and objectivity. The result showed that the generally teachers have a desirable recognitions about a nature of science. For attitudes toward teaching nature of science, the teachers showed that they have positive attitudes. However between degrees of teachers' recognition about a nature of science and attitudes toward teaching nature of science showed a low correlation. To increase their understanding of nature of science and develop attitudes toward teaching nature of science, there should be more training time for the teachers and training contents also should be changed. In addition, we hope that this study contribute to develop contents and direction of training for the teachers as a basic reference.

  • In this study, we propose research methods to explore the nature of earth science by applying the phenomenological approach and NOS-family resemblance approach based on literature review. The phenomenological approach exploring the nature of earth science is a method of collecting, analyzing and synthesizing multifaceted features of earth science from intuitive sensory phenomena without prejudice. As a way of exploring the nature of earth science from a phenomenological point of view, we propose the NOS-family resemblance approach to the NOS. This approach provides a comprehensive explanation of NOS by combining the characteristics shared by different areas of science with distinct differences. Applying this method to exploring the nature of earth science, we can identify both domain-general and domain-specific characteristics that make sub-areas of earth science a 'family.' For example, through the networking of features shared by such sub-areas as geology, atmospheric science, oceanography, astronomy, earth system science, etc., we can extract the family-resemblance characteristics that make these sub-areas a family called earth science. Through these approaches to the nature of earth science, the richness, complexity, and dynamic nature of earth science can be revealed as a whole. In addition, we will be able to grasp the change in the sub-areas that constitute the earth science, which in turn changes the nature of earth science, and to contribute to establishing the status and development system of earth science as a school subject.
