In this study, the relationships between university students and their perceptions of gender roles and epistemological beliefs were investigated. Gender roles are a phenomenon that are determined by culture, and begin to emerge at an early age, which may include some stereotypical behaviors along with a number of attitudes, duties and obligations that the individual is expected to perform as a woman or a man. Epistemological belief is seen as an individual feature of how knowing and learning take place. In this study, a mixed method was used. The quantitative study group consists of 517 students from both universities, while the qualitative study group consists of 85 people. Gender Role Attitudes Scale and Epistemological Beliefs Scale were used to collect quantitative data. In order to obtain qualitative data, participants were given a form consisting of open-ended questions. According to the analyses, it was determined that there was a significant relationship between the participants' epistemological beliefs and gender roles attitudes and, epistemological beliefs were a significant predictor of gender roles attitudes. The results obtained are discussed in line with the existing literature.
