The aim of this study is to determine preservice science teachers’ knowledge and views about nature of science. Phenomenology, one of the qualitative research designs, was used in this study. The study group was determined with the appropriate situation (easily accessible situation) sampling, which is one of the purposive sampling methods. The study group comprised eight pre-service science teachers studying in the third and fourth grades of science teaching at the Faculty of Education of a University in the Central Anatolia Region. As a data collection tool, the Form of Opinions on the Nature of Science (VNOS-C), which was rearranged by the researchers, was applied during the course process. During the research process, interviews with the participants were recorded by taking permission from the participants. After the voice recordings were written, content analysis was performed by creating codes, categories and themes. Validity-reliability studies were carried out at every stage of the study process. According to the results of the study, it was observed that there were errors and deficiencies in the knowledge and opinions of preservice science teachers about the nature of science and scientific knowledge. In addition, it was observed that all preservice teacher participating in the study were at the "expert" level in the dimensions of " The influence of imagination and creativity on science" and " The effect of social and cultural values on science ", and mostly third grade preservice teacher were at the "expert" level in all other dimensions.
