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 participants’ responses were analyzed and new DM model named the Fractal Model of DM which reflects real life situation DM process especially referendum case was constructed. In DM, NOS lens usages of five NOS aspects about creativity and imagination, observation and inference, empirical-basis, subjectivity, and social and cultural embeddedness, and, 23 other lens usages such as animal rights (morality), economic, risk factor etc. were detected and explained through the Fractal Model. It was understood that, with multiple lens usage, each participant had multi-perspective considerations in DM. While Group S used NOS lenses mainly parallel with their NOS understandings, in same case Group U used NOS lenses in a more complicated way. Generally, Group U with rational ritualism and Group S with go-for-it approach ended the referendum simulation with YES for sale of the artificial meat in Turkish markets. Three participants with mixed-scanning voted NO and they were only participants who used sophisticatedly NOS lens about empirical-basis in their decision.

Investigation of Preservice Science Teachers' Nature of Science Understanding and Decision Making on Socioscientific Issue through the Fractal Model
Adal, Elif Ece; Çakıroğlu, Jale (2022-01-01)
The paper reports a qualitative study to reveal how preservice science teachers' decision making (DM) processes on socioscientific issue (SSI) in a referendum case compare between unsophisticated (Group U) and sophisticated (Group S) views 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, one-on-one semi-structured in-depth interviews of the main study for DM on SSI, the artificial meat was d...
DEVELOPMENT OF NATURE OF SCIENCE SCALE (NSS) FOR ADVANCED SCIENCE STUDENTS
Koksal, Mustafa Serdar; Çakıroğlu, Jale (2010-01-01)
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 ...
Investigation of the preservice science teachers̕ views on science technology and society issues
Kahyaoğlu, Elvan; Çakıroğlu, Jale; Department of Secondary Science and Mathematics Education (2004)
The aim of this study is to investigate the views of preservice science teachers on science-technology-society, STS, issue. A total of 176 preservice science teachers participated in the study. A 26-item أViews on Science-Technology-Society (VOSTS)ؤ instrument, translated and adapted into Turkish, were utilized to assess participants̕ views on STS. The VOSTS (Aikenhead, Ryan and Fleming, 1989) is a pool of 114 empirically developed multiple-choice items with nine categories. In order to understand participa...
A new fuzzy-chaotic modelling proposal for medical diagnostic processes
Beyan, Timur; Baykal, Nazife; Department of Information Systems (2005)
Main reason of this study is to set forth the internal paradox of the basic approach of the artificial intelligence in the medical field to by discussing on the theoretical and application levels and to suggest solutions in theory and practice against that. In order to rule out the internal paradox in the medical decision support systematic, a new medical model is suggested and based on this, concepts such as disease, health, etiology, diagnosis and treatment are questioned. Meanwhile, with the current scie...
Investigation of undergraduate students' mental models about the quantization of physical observables
Didiş, Nilüfer; Eryılmaz, Ali; Erkoç, Şakir; Department of Secondary Science and Mathematics Education (2012)
The purpose of this research is to investigate undergraduate students’ mental models about the quantization of physical observables. The research was guided by ethnography, case study, and content analysis integrated to each other. It focused on second-year physics and physics education students, who were taking the Modern Physics course at the Department of Physics, at Middle East Technical University. Wide range of data was collected by interview, observation, test, diary, and other documents during 2008-...
