  • This study searched secondary school students' epistemological views and ontological views about nature and the root causes of such their views. The subjects were 156 secondary school students and data were gathered by the questionnaire developed based on preceding researches. As a result, many secondary school students had epistemological views of unknowable nature. There were various root causes of their epistemological views such as regularity and harmony of nature, predictable and circular natural phenomenon, causation, the relation between human and nature. On the other hand, a lot of secondary school students had ontological view of supernatural nature. Their religious beliefs were very powerful influence their supernatural ontological views. The nature is the object of science and the physical world. Because those views supply science educators basic backgrounds how leaners understand science class, secondary school students' epistemological views and ontological views are precious information. From now on, it is necessary to study relations between students' epistemological views and ontological views and their science class processes.

  • The purpose of this study is to examine Korean journals related to science education in order to analyze research trends into Nature of science in Korea. The subject of the study is the level of Korean Citation Index (KCI-listed, KCI listing candidates), that can be searched by the key phrase, "Nature of science" in Korean language through the RISS service. In this study, the Descriptive Statistical Analysis Method is utilized to discover the number of research articles, classifying them by year and by journal. Also, the Sementic Network Analysis was conducted to Word Cloud Analysis the frequency of key words, Centrality Analysis, co-occurrence and Cluster Dendrogram Analysis throughout a variety of research articles. The results show that 91 research papers were published in 25 journals from 1991 to 2015. Specifically, the 2 major journals published more than 50% of the total papers. In relation to research fields., In addition, key phrases, such as 'Analysis', 'recognition', 'lessons', 'science textbook', 'History of Science' and 'influence' are the most frequently used among the research studies. Finally, there are small language networks that appear concurrently as below: [Nature of science - high school student - recognize], [Explicit - lesson - effect], [elementary school - science textbook - analysis]. Research topic have been gradually diversified. However, many studies still put their focus on analysis and research aspects, and there have been little research on the Teaching and learning methods.

  • In this study, the relationship between students' out-of-school science experience and their view on the nature of science was investigated. The participants were 267 sixth graders, 281 eighth graders, and 307 tenth graders from schools in Seoul. A test of views on the nature of science which consists of five items concerning the purpose of science, the definition of scientific theory, the nature of scientific model, the tentativeness of scientific theory, and the origin of scientific theory was administered. Students' out-of-school science experiences were measured with a subscale of the modified Science Experience Survey consisting of seven items. The results indicated that no statistically significant relationship was found between students' out-of-school science experience and their view on the nature of science in sixth graders. In eighth graders, high level students in terms of out-of-school science experiences were found to possess more contemporarily epistemological view in the item concerning the nature of scientific model but more falsificationist view in the item concerning the tentativeness of scientific theory. High level tenth graders in terms of out-of-school science experiences exhibited more epistemologically sophisticated understandings of the nature of science than their counterparts in the items concerning the purpose of science, the definition of scientific theory, and the nature of scientific model.

  • The main purpose of this study is to examine the effects of explicit instructions on the nature of science (NOS) on the understanding of science-gifted students. Participants were engaged in 8 explicit NOS instructions spanning 6 months. Data were collected before and after the instructions from 20 science-gifted students using student worksheets, open-ended questionnaires (Views of Nature Of Science, VNOS), and in-depth interviews. The results of this study showed that explicit instructions were helpful in improving the understanding of the tentativeness in science and socially and culturally embedded aspects of science. However, participants not only still possess naive views on the nature of science about the distinction of law and theory and the empirical aspects of science, but also had conflicting views and misconceptions in some areas. The study has implication for development of science-gifted program that the explicit instructions on NOS and science inquiry should be provided concurrently, given the complementary relationship of the two activities.

  • The objective of this study is developing an instrument for investigating views of the respondents on nature of science(NOS) by using experienced scientific knowledge, atomic model. It consists of total six questions and 36 detail items, and each question is reflected the aspects of different NOS which are 'recognition on the model', 'tentativeness of scientific knowledge', 'subjectivity in science', 'use of inference and imagination', 'myths of the scientific method', and 'comparison between science and art'. Particularly, 'comparison between science and art' is addressed almost for the first time in this questionnaire. In the class environment almost not to teach nature of science linking with concrete scientific knowledge, to inquire how the students recognize nature of science, relating to experienced scientific knowledge through this questionnaire will give the data of scientific knowledge based recognition on the nature of science and an important implication for nature of science teaching with concrete scientific knowledge. Developing processes have gone through four steps. In first step, we chose aspects of NOS and developed questions and details. In second step, we tested the draft into fifteen science teachers and, reflecting their opinions, corrected the form and contents of questionnaires. In third step, we tested the questionnaire included writing section for expressing thoughts of the respondents into 55 students in science high school and checked index of coincidence between Likert and open-ended responses which shows 88.2% degree of consensus. Furthermore, to identify the feature of using concrete scientific knowledge we applied this and views on science and education questionnaires together into six university students. We performed final test to 68 university students and measured Cronbach's, and ultimately completed final questionnaire in last step.

  • This qualitative study investigated two preservice teachers' conceptual ecologies in professional development during the science teacher preparation program. The notion of a conceptual ecology contains nature of knowledge, science and science teaching, learning, and content knowledge and comfort level. The data were collected during the participants' preservice year and their practicum experience. Both data collections and analyzing were from the various sources of interviews, teaching observations, journals, and information and profiles by the participants' supervisor. Two preservice teachers serve as cases representative of this study. Results show that problems preventing the preservice teachers from moving closer to conceptual change teaching were their understandings of the nature of science and the nature of knowledge. The preservice teachers' views about knowledge come from, and what knowledge is, are largely shaped by the nature of science and learning drive pedagogy and classroom practice. Knowledge of and comfort with the subject matter are also important.

  • The purpose of this study is to develop a nature friendly education program that would support ecological literacy of preschool children and to examine the effects of the program on their ecological knowledge and positive attitudes toward nature. The subjects of the study were 59 children from two child-care centers located at Gyeonggi Province. 30 preschoolers from one center were allocated into an experimental group, while 29 preschoolers from the other center were regarded as the control group. The program was composed of 24 sessions, performed three times a week for 20-30 minutes from May to June 2009. The instrument included the knowledge and attitudes toward the environmental scale for preschool children. The following results were obtained. First, the experimental group was found to attain higher level of ecological knowledge and more positive attitudes about nature as a result of the program. Second, after the program was administrated, the experimental group showed higher level of the knowledge and more positive attitudes about nature than the control group. These results suggest a program which conducts within a integrated teaching frame of meeting and getting familiar with nature and taking care of animals and plants, can become an effective early childhood education tool which fosters positive attitudes and knowledge concerning the environment.

  • The purpose of this study is to develop scientist vignettes and to explore their effects to change students' perceptions of scientists, scientific attitudes, and the nature of science. The scientist vignettes developed in this study include research cases on seven scientists, including British zoologist Jane Goodall. Each vignette consists of 4 to 6 pages in consideration of the reading level of elementary school students, and contains illustrations describing the main contents of the text. In addition, scientist vignettes contain descriptions on terms and text boxes explaining the higher concepts, and each vignette contains questions that students can think deeply based on the story of the scientist. To verify the educational effectiveness of scientist vignettes, we investigated changes in their perceptions of scientists, scientific attitudes, and the nature of science in 564 elementary school students. We conducted group interviews with four elementary school teachers. As a result of conducting pre-test and post-test using a narrative questionnaire consisting of 6 questions, students became more sophisticated in the understanding of the science and the characteristics of scientists after experiencing scientist vignettes and their understanding the nature of science changed into a more modern epistemological perspective. Also, in a group interview with teachers, teachers assessed that scientist vignettes would positively affect the understanding of science process skills and the nature of science, and forming a scientific attitude, especially in increasing understanding of the nature of science. We discussed ways to effectively utilize scientist vignettes in elementary school science education based on these result.

  • The purpose of this study was to examine university students' understanding of the nature of science, an aspect of scientific literacy, which is the goal of modern science education. To accomplish this, the differences and similarities by gender and major. on college students' understanding of the nature of science were investigated. 'Understanding of the Nature of Science' developed by Lee (2003) was implemented for this study. The instrument has three sub-scales; a scientific world view, scientific inquiry, and scientific enterprise. The instrument is only expected to give, and provides meaningful information on student understanding of the nature of science. A total of 120 college students, majoring in science education, liberal arts, and physical exercise participated in this study. Science education major students were verified to have a better understanding of the nature of science followed by liberal arts students and then physical exercise students. Moreover, men revealed slightly more comprehension that of women. More than 80% of students, majoring in science education, answered 11 out of 23 questions, approximately 50%. In the area of scientific inquiry, both science education and liberal arts students showed more comprehension that those in physical exercise. All participants showed relatively lower comprehension of the definition of scientific contribution than other subjects, but displayed a greater comprehension of the ethics of science. On the other hand, most students have relatively low apprehension in the contribution of science, while higher apprehension in the ethics of science.
