  • 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.

  • The purpose of this study was to analyze epistemological beliefs in science as perceived by elementary school students and to examine the purpose of science, the nature of scientific knowledge, the source of scientific knowledge, and the role of experimentation. The subjects of this study were 99 elementary school students. As a tool for examining epistemological beliefs in science, we used adapted questionnaires comprising elements constituting epistemological beliefs, as proposed by Elder (1999). The results of the analysis are as follows: First, in terms of the purpose of science, sixth graders had the most modern beliefs compared to other grades. Second, a statistical significance was found between fourth graders and students in other grades based on the analysis of the nature of scientific knowledge. Third, there was no significant difference in each grade's beliefs concerning the source of scientific knowledge or the role of the experiment.

  • The purpose of this study is to gain an understanding of scientifically gifted students' views on the nature of science. A multiple-choice format questionnaire was administered to 237 Korean 10th, 11th and 12th graders at the Korea Science Academy. The differences and similarities by gender and experience of R&E program on the students' views of the nature of science were investigated. The questionnaire developed by Lim(2004) was implemented for this investigation. We found that the majority of scientifically gifted students had highly possessed the tentativeness of scientific knowledge. The students who experienced R&E program have relatively high apprehension of scientists' motivation for researches and activities in social context compared to the students who did not experience an R&E program. Scientifically gifted students had relatively high apprehension that government should not control researches of scientists and relatively low apprehension of social responsibilities of scientists comparing to general high school students. The experience on R&E program was identified as a factor to effect changes in the students' views on the nature of science. The study has implications for the development of gifted program and curriculum such as running and assessing R&E program, and also the pre-service preparation of science teacher, teacher education reformat in both the practical and the policy levels.

  • The purpose of this study was to develop, field test an instrument to assess secondary school students' conceptions of the nature of science. The instrument named Philosophical Perspectives Probe(PPP) is a pool of 24 multiple-choice items that address a wide range of philosophical topics of science. The statements and the choices of this instrument were derived from an analysis of various philosophical positions. The main philosophical systems of the instrument are inductivism, falsificationism, and relativism, respectively. Major distinctions depend on the issues of the criteria of demarcation, patterns of scienctific change, epistemological status of scientific knowledge, and the scientific methods. The researchers also offer teachers a new way of assessing and interpreting their students' conceptions on a wide variety of topics related to the nature of science.

A Study on the Understanding about Nature of Scientific Knowledge and Attitude toward Scientific Inquiry of Pre-service Science Teacher through Open Inquiry (개방형 탐구를 경험한 예비과학교사의 과학 지식의 본성에 대한 이해와 과학 탐구에 대한 태도 변화)

  • The purpose of this study is to investigate the understanding of nature of scientific knowledge and attitudes toward scientific inquiry of pre-service science teachers experienced open inquiry. The study was conducted in 10 sessions of open inquiry-based chemistry experiment. The subjects were 40 pre-service science teachers recruited from the experiment class. They received pre-test, mid-test, post-test on understanding nature of scientific knowledge and attitudes toward scientific inquiry of open inquiry activities. 20 pre-service science teachers among them participated in the interview. The results of this study are as follows. First, there was a significant difference in pre-service science teachers' understanding of the nature of the scientific knowledge (p<.05). In particular, understanding of creativity and sociality parts improved gradually. Second, pre-service science teachers' attitude toward scientific inquiry had changed negatively until the middle of the semester, and then changed positively later. The post-test score was significantly higher than the mid-test score (p<.05).

  • This study aimed to explore elementary teachers' beliefs about science teaching, science learning and the nature of science and consistency among these beliefs. Data was collected by using an open questionnaire and semi-structured individual interview. Teachers' beliefs were classified as traditional beliefs and constructivist beliefs. Traditional beliefs were further divided into content knowledge-centered beliefs and procedural knowledge-centered beliefs. The result showed that a relatively large number of teachers among the total 30 teachers had traditional beliefs about science teaching, science learning, and the nature of science(respectively 60.0%, 66.7%, 83.3%). Most of traditional beliefs were identified as content knowledge-centered beliefs. The proportion of teachers with consistent beliefs for all three aspects was 40.0%, the proportion of those with consistent beliefs for two of them (those with related beliefs) was 53.3%, the proportion of those with different beliefs for them (those with divergent belief) was 6.7%. Most of the teachers with the consistent beliefs had the content knowledge-centered beliefs of traditional beliefs. Although constructivism has been widely emphasized in science education from the 1980's, the rate of the teachers with the consistent beliefs in constructivism was as low as 6.7%.

  • Scientific observation has been recognized as one of the fundamental aspects in scientific inquiry. However, more detailed discussions and practical guides for teachers' and students' understanding about the nature of scientific observation have not been conducted. Therefore, based on literature reviews, we described the nature of theory-laden scientific observation as 11 detailed statements. Using theses statements, we investigated science teachers' and students' recognition of each statement. According to results, certain aspects of theory-laden scientific observation were determined as important aspects to be considered for science teachers' in-service programs or for students' learning activities in understanding the nature of science.
