Mathematical modeling is the one of the prominent research areas in establishing connections between real life and mathematics. Future teachers need to be competent about mathematical modeling so that their students experience the learning environments that enable them to move between mathematical world and real-world. Before practicing, pre-service teachers ought to have a grasp of basic knowledge about nature of mathematical modeling. In this context, a theoretical program was developed within the scope of action research and forty pre-service secondary mathematics teachers, nineteen of them in the pilot study and twenty one of them in the main study, participated to the study. Data was collected through open-ended questionnaire, observation notes and video recordings and analyzed by content analysis. While it was found that the participants had perceptions about model and modeling concepts relating to concrete teaching materials, mock-up and role model at the beginning of the study; it was reached that their answers were close to the definitions of mathematical model and modeling concepts in the literature at the end of the study. It was concluded that the program carried out in the study enabled pre-service teachers to enhance their knowledge about the nature of mathematical modeling.
