The research was applied in 2010 academic year in the province of Burdur which is in the first numbers in the overall success of national examinations in Turkey. In this context, semi-structure questionnaire which consists of 3 parts was applied to 8 science teachers through individual interviews.

The last part is about the place of NOS in science curriculum, science teaching and teacher's self-assessments. According to results of research, it is found those science teacher's views about nature of classification schemes and scientific experiments are sufficient but the most of teachers have naive and insufficient level of views about the concept of science, scientific method, law and theory. Besides, it can be said that teacher's views about NOS models and observations are complex.
