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).

This study aims to find out science talented students' percentage of cognition about the views of nature of science and science inquiry which are essential for having a good understanding with science concepts. Each group of 40 science gifted students and 35 ordinary students was tested with a test of views of nature of science and science inquiry which consisted of 19 items with index of content validity 97% and reliability index 0.86, then its results being compared and analyzed. A group of science gifted students' percentage of cognition about the views of nature of science ranges from 20% to 97.5% -although it differs according to detailed views-showing its mean of 67% (50% in a group of ordinary students). Especially, the percentage of cognition about the sub view that there can be different opinions among scientists was high among woman science gifted students. A group of science gifted students' percentage of cognition about the views of science inquiry ranges from 27.5% to 77.5% -although it differs according to detailed views- showing 53% in their mean (41.8% in a group of ordinary students). Especially, the percentage of cognition about the sub view that scientists can have different research methods was high among woman science gifted students. The percentage of mistaken cognition by science gifted students about views of nature of science and about views of science inquiry was 33%, 47% respectively.

In order to teach the nature of science which is one of the goals of science education, the aesthetic model of science was developed into a two-dimensional model through theoretical reviews on the aesthetic aspect of science. We represented 10 kinds of scientific experiments that scientists thought are beautiful in the aesthetic space of science. This paper tried to represent the greatest and famous scientific experiments in the history of science into the aesthetic space of science to find the suitability or usefulness of that model. At the same time, we were able to develop measuring tools as the Likert-scale with pictures of scientific experiments. Through this, we propose various teaching approaches on the nature of science (NOS) based on the aesthetic model of science and the potential for utilization in measuring the effects of the ways of teaching NOS.

The nature of science has been recognized in a great deal in the field of science education. However, only few innovative programs are offered for science-gifted students to improve their recognition of the nature of science. The current study describes and analyzes science-gifted students' understandings of the nature of science (NOS). In addition, the study looks into contradictory views among the aspects of NOS, which are fundamental data in constructing target programs on NOS for science gifted students. Data used in this study were collected from 73 middle school science-gifted students using an open-ended questionnaire, VNOS. The results of this study showed that the participants' understanding of NOS was significantly distributed on naive or transition view except for 'tentative NOS', and the results revealed inconsistent view among the aspects of NOS. This study proposes two suggestions to enhance the recognition of science-gifted on NOS of science to informed state and to have consistent perspectives with other areas. First, the role of experiment has to be changed-it should be the process in constructing scientific knowledge rather than an instrument to check scientific knowledge to transform perspective on experimental data and scientific knowledge. Second, various opportunities must be provided to science-gifted students, so they can experience the culture and community of scientists and science to gain a wider insight of science.

This study investigated whether there was a difference of the change in perspective of the nature of science depending on subjects of the history of science, after designing for two kinds of topics of role play programs based on the history of science to be transformed into a modern perspective. Before the history of science-role plays, the degree of the modern perspective was statistically no difference between group I(the atomic model transition-role play) and group II(the Mendeleev's periodic table-role play). However after treatment of the history of science-role plays for the each group, the degree of group I was higher than the degree of group II in the modern perspective. The results of this study indicate that the degree of changes into modern perspective of the nature of science by performing a history of science-role play may be depend on the subject of the history of science combined with the role play, and suggest the possibility that may be more effective to change the nature of science into the modern perspective, in case of performing of role play based on the history of science that includes the scientific knowledge established by a number of scientists with time series.

In line with the emphasis on the importance of nature of science recently, this paper examines the degree and level at which the 2009-revised convergence science textbook, developed from the common science under the 7th curriculum in South Korea, reflected nature of science according to the development of curriculum. 'Nature of science' was classified according to scientific view - which represents scientists' view - and naive view - which represents general thinking and scientific error concepts. Also, 'Nature of science' was classified according to the explicit method and implicit method in terms of teaching method. The level of nature of science was defined using the four occasions of scientific view, naive view, explicit teaching and implicit teaching. In order to identify the components and level of nature of science reflected in the textbook, using the 10 items which refer to Lederman(2001)'s 7 definitions, NOSAT (Nature of Science Analyzing Tool) was developed and used. The results are that, since the educational curriculum is changed from common science under 7th curriculum to 2009-revised convergence science, the degree of reflection was rather a withdrawal. On parts of theories of 7th common science curriculum except research parts, it was difficult to find explicit nature of science. Also on 2009-revised curriculum, nature of science, which is seen on 2007 curriculum, disappeared. It is suggested that the future curriculum emphasizes the importance of nature of science, and bolster the reflection of nature of science according to the changing curriculum. Nature of science should not be expressed limitedly, but instead, should be more positively reflected, and the reflection method should be not implicit but explicit, allowing direct teaching. Towards that end, writers of the textbook should have an accurate understanding of nature of science. And, for the right teaching, teachers' capabilities are important and it is necessary to train teachers to understand and act for nature of science.

The purpose of this study is to analyze the difficulties with scientific research faced by leading Korean scientists and suggest implications for science education. Data were collected through semi-structured interviews with 13 leading Korean scientists and were qualitatively analyzed using constructivist grounded theory. The results of the study showed that the leading scientists encountered 11 subcategories of difficulties, which were grouped into three main categories: uncharted territory, unexpected situations, and a lack of resources in domestic research environments. 'Uncharted territory' comprised anxiety due to uncertainty about research performance, insufficient knowledge accumulation in the field of research, and the burden of maintaining research influence as an academic leader. 'Unexpected situations' included encountering new phenomena that cannot be explained by existing theories, an inability to utilize research results, and repeated failures. 'A lack of resources in domestic research environments' included inadequate research funding support systems, a shortage of expert networks, limitations on employment and career opportunities for students, poor research equipment, and insufficient support policies for retired researchers. This study provides science educators with implications for the direction of science education and R&E. For students, it can serve as career education material, their attitudes towards science and their understanding of its nature. Lastly, the study may contribute to finding ways to improve scientific research policies and to developing a culture that fosters expertise in science.

The purpose of this study was to examine preservice secondary science teachers' understanding of the nature of science, by using nature of science (NOS) questionnaire on the basis of atomic model, and compare this to pre-studies. 'Understanding of nature of scientific model,' 'Tentativeness of scientific knowledge,' 'Subjectivity in science,' 'Use of inference and imagination,' 'Myths of the scientific method,' and 'Comparison between science and art.' were examined. Preservice teachers showed great comprehension of the tentativeness of scientific knowledge (the orbital model) and the subjectivity in science (the different interpretation about the experiment of particle scattering), but displayed the lowest comprehension of the scientific method. For understanding of nature of scientific model (the atomic model) and the comparison between science (Bohr's atomic model) and art (Picasso's work), preservice teachers brought out a combination of ontological and constructivist perspective and showed the contradictory thought about imagination in science research. In the result of comparison to pre-studies using the NOS instruments contains general terms, represented high levels of agreement about the tentativeness of scientific knowledge by using concrete examples of 'atomic model'. When concrete scientists such as Thomson, Rutherford, Bohr were presented, respondents revealed more informed views about the scientists' research method.

This study aims to investigate tenth graders' understanding of the nature of scientific inquiry (NOSI). A total of 100 public school students participated. A questionnaire of Views about Scientific Inquiry was used to assess their understanding of the NOSI, and data were collected using qualitative research methods such as open-ended questionnaires and, when necessary, semi-structured interviews. By employing a constant comparison method to analyze their responses, five students were consistently categorized as the group with informed views regarding all the eight aspects of the NOSI. The rest of the students showed different levels of understanding regarding each aspect. A large portion of the students represented a group with mixed views about four aspects and informed views about three aspects, whereas naive views about one aspect prevailed among them. The results showed that many students comparatively lacked understanding of the aspect related to the scientists' process of constructing explanations and formulating theories. This study discusses the relationship between its results and the current science curriculum and presents implications for the overall enhancement of students' understanding of the NOSI. Finally, it encourages the acquisition of scientific inquiry ability and makes suggestions to promote further studies.
