The aim of this study is to determine pre-service classroom teachers' beliefs and thoughts about the roles of teachers and students in the classroom before taking the Mathematics Teaching I course. With this purpose, the study employed the survey method, a descriptive research technique. The study sample included 75 pre-service teachers (55 females and 20 males) who studied in Omer Halisdemir University's education faculty's primary level teaching department classroom teaching programme in the 2013-2014 academic year, and took the Mathematics Teaching I course. The study data were collected using a survey form including three open-ended structured questions. The data were analysed using the qualitative data analysis method. The study results indicated that the pre-service teachers' beliefs, in terms of both teachers' and students' roles, were between the absolute and transitional levels based on Baxter Magolda's epistemological reflection model. This reveals that pre-service teachers' beliefs are in line with conventional teaching and learning approaches.
