The participants were 406 high school students studying in Batman and Diyarbakır infall of 2012 who were considered under two separate study groups. Expert review was done to check content and face validity. The exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were performed in order to check construct validity. As a result of the EFA, a 27-itemthree-factor structure emerged, explaining 40.57%of variance. The emerging factors were called as a belief of that learning depends on effort (BLDE), a belief of that learning depends on talent (BLDT), and a belief of that there is only one truth (BTOOT). The findings indicated all 27 items and a three-factor structure related to the MOEBS have satisfactory indices of goodness of fit.As a result of reliability analysis, it was determined that internal consistency and test-retest coefficients were acceptable.The findings of the item analyses showed that all of the items were discriminatory. In light of these findings, it can be argued that the scale is reliable and valid and can be used to measure high school students’ mathematics-oriented epistemological beliefs.}, number={3}, publisher={Afyon Kocatepe Üniversitesi}
