In this study; the effects on the ethnocentrism levels of prospective teachers have been examined upon providing education under the scope of intercultural education. The study has been designed as a quasi-experimental design with pre-test, final-test control group. The study took place during the spring semester of 2014-2015 academic year. The study group consists of a total of 118 prospective teachers, 74 of whom (trial group) are students at a public university in Ankara and 44 (control group) from a public university in Nigde. At the beginning and end of the study, the ethnocentrism levels of the prospective teachers have been assessed. The 20-item Ethnocentrism Scale has been used as the data collection tool. In order to interpret the points scored in "Ethnocentrism Scale", an independent sample t-test and "One-Way Covariance" analysis have been used. The research findings indicated a positive oriented change in the ethnocentrism points and between both the trial and control group students' pre- and final test grade averages in the in-group comparisons. However, this positive change was in favour of the trial group in the inter-group comparisons. In other words, the project assignment made by the prospective teachers had a positive impact on the students' ethnocentrism levels.
