An Alternative Method For Assessing Views About The Nature of Science: Vignettes The aim of this study is to determine the effectiveness of the short stories (vignette) for assessing the pre service science teachers' views about the nature of science. For this purpose, the validity and reliability studies of vignettes and rubrics used in the research are given. The research comprised two stages: the pilot and the authentic application. The piloting was carried out in 2009 spring term with the participation of 90 pre service science teachers who had taken History and Nature of Science course while the main study included 79 pre service teachers in 2010 spring term. At the end of the analyses positive results were obtained as to the validity and reliability of vignettes. It was understood that vignettes can be used as a method of determining opinions on the nature of science.
