Abstract: One of the significant goals of science classes is to make students to understand nature of science appropriately. However, there are many myths related to nature of science. It is known that those myths may be as a result of science education in schools. Although the traditional views about nature of science are widely reported to be quite common, there is no certain evidence whether a person who has got realistic views about nature of science is more successful or better decision-maker. In this context, pre-service science teachers’ views about nature of science was examined and the relationship of their views with their decision-making skills. This research is a cross-sectional survey study and the data was collected through the use of Views of Nature of Science Questionnaire (VNOS) and Simple Electric Circuits Three-Tier Test (SECTT) from64preservice science teachers. Consequently, it has been observed that pre-service science teachers possess (1) merit and realistic views about definition of science and characteristics of scientists, (2) naïve and merit views about social structure of scientific knowledge, and (3)naïve and realistic views about characteristics of scientific knowledge. Also, a statistically significant relationship between pre-service science teachers’ views about nature of science and their decision-making skills was observed.
