SMK of NOS of the pre-service teachers is determined by the researcher using "Views on The Nature of Science (VONS)" questionnaire which is adapted to Turkish from VOSTS (Views on Science-Technology-Society) questionnaire. In this survey study descriptive model is used. In this regard, the pre-service teachers' responses on the VONS are analyzed based on subject matter experts' encodings. According to the results, pre-service science teachers have enough SMK about some issues such as tentativeness of scientific knowledge, scientific approach for researches and public influence on scientists. However, SMK of NOS of pre-service science teachers is not in a level to develop the students' level of understandings and knowledge of NOS. Pre-service teachers' insufficient SMKs are related to scientific theories, laws and hypothesis also their epistemological status and nature of scientific models
