The focus of the latest research moves from students and their understanding of teachers and preservice teachers. One of the most important reasons for this movement is the proven impact of the knowledge, skills, attitudes and beliefs teachers have on the educational decisions taken at teaching and learning environments. In light of this fact, the aim is to familiarize mathematic students with the process of mathematics teaching with role play and to help them re-examine their traditional views of mathematics learning and teaching. The mathematic students made effective use of their mathematical knowledge and ideas when they played their role in problem-solving. They also began to realize that if they behave in a slightly different way, others may also modify their behaviour, and problems become easier to solve.
