Frequent use of open-ended questionnaire plus interview application for nature of science as a requirement for informed decision making has been criticized by many researchers and a need for an easily administrable and scorable instrument has been emphasized. At the same time, existing instruments were developed with the students out of advanced students. Therefore, the purpose of this study is development of a nature of science scale for advanced science students. The study was conducted with 224 advanced science students. Both confirmatory and exploratory factor analysis were done to collect evidence for validity of the scores on the instrument and it was found that both of the analyses approved appropriate validity of the scores. Cronbach alphas for subscales were found as from .55 to .77 as acceptable values. The implications and importance of the instrument will be discussed in this article.


Development and validation of nature of science instrument for elementary school students
HACIEMİNOĞLU, ESME; Yılmaz Tüzün, Özgül; ERTEPINAR, HAMİDE (2014-05-01)
The purposes of this study were to develop and validate an instrument for assessing elementary students’ nature of science (NOS) views and to explain the elementary school students’ NOS views, in terms of varying grade levels and gender. The sample included 782 students enrolled in sixth, seventh, and eighth grades. Exploratory factor analysis factor structures and confirmatory factor analysis fit indices confirmed the existence of the hypothesised four dimensions in the structure of the nature of science i...
Investigation of preservice science teachers’ nature of science understanding and decision making on socioscientific issue through the fractal model
Adal, Elif Ece; Çakıroğlu, Jale; Department of Elementary Education (2019)
This is a qualitative grounded theory study to reveal how decision making (DM) processes on socioscientific issue (SSI) in a referendum case are operated by unsophisticated (Group U) and sophisticated (Group S) ones in terms of nature of science (NOS) understandings. Firstly, pre-study was conducted with focus group interviews with pre-service science teachers. With the findings, semi-structured in-depth interviews of main study for DM on SSI- the artificial meat was developed. In main study, 12 participant...

Demirdöğen, Betül; Kondakçı, Esen; Köseoğlu, Fitnat; Department of Secondary Science and Mathematics Education (2012)
The purpose of this study was to delve into the complexities of development of preservice chemistry teachers’ science teaching orientation, knowledge of learner, knowledge of instructional strategies, and knowledge of assessment during Pedagogical Content Knowledge (PCK) for Nature of Science (NOS) instruction. Thirty pre-service chemistry teachers enrolled Research in Science Education course participated to the study. Case study, one of the qualitative research methods, was used as research design. PCK fo...
Research Assistants' Suggestions on the Improvement of Graduate Programs Regarding Science Perception
Yasan, Nehir; Yıldırım, İbrahim Soner; MEDENI, Tunc (2013-02-08)
The purpose of this study was to explore research assistants' opinions to improve science perception at graduate programs. The research questions include the research assistants' suggestions on the improvement of the graduate program regarding science perception and, in this respect, what their suggestions about a possible course. The sample for the present study contains 12 interviewees from four different institutes of Middle East Technical University. The interviewees are all PhD candidates at METU. The ...
Investigation of the relationship between pre-service science teachers' understandings of nature of science and their personal characteristics
Çetinkaya, Gamze; Çakıroğlu, Jale; Department of Elementary Science and Mathematics Education (2012)
The purpose of this study was to investigate the possible relationships between pre-service science teachers' understanding of nature of science (NOS) and their personal characteristics; understanding of nature of scientific inquiry (NOSI), epistemological world views, self-efficacy beliefs regarding science teaching, attitudes towards science teaching, metacognitive awareness level and faith/worldview schemas. The sample of the present study were 60 PSTs that are 3rd year students at elementary science edu...
