The purpose of this study was to analyze the introduced contents and the nature of science on the history of science in elementary school science textbooks according to the 2009 revised curriculum. For this purpose, first of all, the frequency of contents of history of science in 8 kinds of science textbooks in elementary school is analyzed by grade cluster and content part. Analysis framework for analyzing the introduced contents on the history of science was characterized with three-dimensional combination of the context, the role and the types(Park, Lee, & Lee, 2011). Analysis framework for the nature of science on the history of science was developed by Leite(2002) and revised by Choi (2005) and Kim(2010) and complemented under one expert in science education. The results of this study are as follows: First, the frequency of contents of history of science in textbook is 26 and it were not equally distributed into science textbooks in elementary school as a result of the analysis by grade cluster and content part. Second, with three-dimensional combination framework only 13 kinds were used in all 48 different types through analyzing the textbooks. It implies that ways of introducing contents of history of science into textbooks were limited to certain types. Third, the nature elements of science were not equally distributed on the history of science in elementary school science textbooks. In conclusion, in order to understand the nature of science through the history of science and to foster scientific literacy ultimately, it implicates that it is need to present various kinds of the history of science for one theme in consideration about the grade cluster and content part. Also more multilateral approach is need to introduce equally distributed into textbooks to reflect the elements of the nature of science.

In this study, we developed a explicit and reflective scientific inquiry learning program about nature of scientific inquiry, and compared its instructional influences with those of implicit scientific inquiry learning. We also compared students' perceptions of the program. Eighth graders at a middle school were assigned to the treatment and the control groups. The students of the treatment group participated in the program, while those of the control group participated in general scientific inquiry instruction. The analyses of the results revealed that the program was more effective in improving students' epistemological views on scientific inquiry than general scientific inquiry learning. However, there were no statistically significant differences in both test scores of science achievement and enjoyment of science lessons. The students of the treatment group perceived that group discussion on the nature of scientific inquiry was an advantage of the program. However, they still had difficulties in performing group discussion, understanding the nature of scientific inquiry, and writing and presenting their thoughts. Educational implications of these findings are discussed.

The purpose of this study was to explore how 9th grade students' understanding of the nature of science developed during a one-year implementation of NOS learning materials. The lessons were a combination of short readings in episodes in the history of science with accompaning response booklets consisting of illustrations and questions. The lessons were designed to be 45 minutes in length and were implemented over ten months of the school term. Data on students' understanding as it developed during the implementation were obtained from test items, questionnaires, and students' journal. Findings indicate that students showed changes in their understanding of the nature of science towards modern views of the nature of science. However, they showed understanding of tentativeness of scientific knowledge, they also showed belief of absoluteness of scientific knowledge.

This study is an investigation regarding the understanding of the nature of science among pre-service science teachers majoring in science education. We interviewed 22 senior students in science education who finished their internship courses. Students were interviewed individually for approximately 20 minutes each. Data from semi-structured interview were audio-recorded and transcribed for the analysis. Findings indicated that participants held more complete understanding of the nature of scientific knowledge than the nature of scientific enterprise. Their understandings of the nature of scientific method was that hypothetical-deductive method is more scientific than descriptive-narrative method and there is a single stepwise scientific method to solve problems. These results showed that they have a narrow view of the nature of science. Thus, teacher education programs need to integrate the understanding of the nature of science throughout.

The purpose of this study was to investigate pre-service biology teachers' perception of the evolution. This study was to compare the views of pre-service biology teachers with no religion with those of christian preservice teachers. Subjects were 77 pre-service biology teachers who enrolled in an university and graduate school of education located in Seoul. The instrument of this study was a questionnaire which consisted of 14 items on 2 domains: the nature of science, the origins of human beings. The key results are as follows. Most pre-service teachers showed highly understanding of the characteristics of science. However pre-service biology teachers still possessed naive views on the distinction of law and theory. In terms of the methods of science, many of the pre-service biology teachers considered scientific theories to progress through the accumulation of observation and experiments or through changes and modifications in existing theories. Compared with the pre-service teachers with no religion, christian pre-service teachers had conflicting views and misconceptions about the origins of human beings. The factors of religion were found to be one of the important barriers which prevent them from understanding the origins of human beings. The results suggested that the education program for pre-service biology teachers integrating the concepts and development process of the scientific knowledges should be effective for understanding the nature of science. For pre-service biology teachers, It is important to understand conflicting views of the christian pre-service teachers who understand creationism as a science.

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.

This study investigated to describe how the nature of science is revealed in the four natural history museums in Korea. Natural history museums are well considered as informal settings of education, and the nature of science has been one of major topics stressed in science education. Therefore, the revelation of this topic is supposedly reflected in developing museum exhibitions. In each of the four target natural history museum or natural history exhibition, the representative exhibits subtitled by scientific inquiry and cases dealing with history of science were selected for the study. The analyzing exhibits focused on whether exhibitions were labeled with emphasis on declarative description or interpretative one. In analyzing the contents, the focus was on the concerns of scientists, scientific community, social and cultural aspects, uncertainty of scientific knowledge, and providing sufficient evidences. All things considered, it was hard to conclude that every target exhibit clearly considered the nature of science as an essential element, in designing and developing their exhibitions. More deliberate input of nature of science is suggested for worldly renowned natural history museums, because previous researches keep insisting that the nature of science would be more efficiently achieved in an informal educational setting rather than in classrooms.

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.

This study is a survey conducted to explore what art high school students specifically see as nature of science. Third-year students of a high school of arts in Gyeonggi-do participated in the survey. The questionnaire was classified into three categories - the formative arts in the fine arts, the sound arts in music, the performing arts in dance, and drama and play. The study analyzed what they think of as similar aspects of science and art respectively according to their majors, with focus on the extracts. As a result, they mentioned 'creative imagination', 'correlation with technology', 'social and cultural relation', 'subjectivity', 'variability', and 'inquiring attitude' as similarities between science and art. The results are almost the same as the elements of the nature of science as agreed on by scientists. From the result, we can assume that students majoring in art, indeed, need an education on the nature of science. Also, while the fine arts students have more tendency to perceive inquiring attitude than others, music students are more likely to perceive variability than others. Therefore, teaching strategy in experimental inquiring context for the former is more helpful in understanding the nature of science, and teaching strategy in the context of scientific history for the latter.

The purpose of this study was to develop 'Science History Based Chemist Inquiry Program' for the science-gifted in high school and investigated the application effects on the understanding toward the nature of science, scientific attitudes, and science career orientation. This study was conducted with one class of 17 scientifically gifted high school students, and the 'Science History Based Chemist Inquiry Program' was applied during 22 class hours. The results of this study were as follows: First, the science gifted students' understanding toward the nature of science showed a statistically significant improvement (approximate significance probability .005). Property of the scientific model, sub-domain of the nature of science, is significantly improved (approximate significance probability .029). This result show that 'Science History Based Chemist Inquiry Program' can improve the scientifically gifted high school students' perception about nature of science. Second, the scientifically gifted students' scientific attitude wasn't changed significantly. However, the openness and creativity in the sub-domains of the scientific attitude showed a statistically significant improvement (p<.05). Third, science career orientation of science-gifted did not show a statistically significant change. But the value of the level of awareness about the science career has been significantly improved (p<.05).
