It can be said that effective development of intercultural sensitivity depends on the regulations and practices in the curriculum. Integrated program implementations are seen as one of the ways of regulation. In the study, a nested integration model was used in a single discipline. In this context, scientific research methods are considered as a discipline, and the achievements of this discipline and intercultural sensitivity development activities are integrated. Understanding different cultures correctly and not being prejudiced are very important for the development of intercultural sensitivity. Scientific research methods course provides students with scientific attitudes and behaviors. In this course, it is thought that students will be able to develop sensitivity by examining different cultures with scientific attitudes and behaviors. In this context, it is aimed to reveal the effectiveness of intercultural sensitization development activities integrated with scientific research methods course gains. The quasi-experimental design with a pretest-posttest and a control group was used in the study. The study group comprised of 86 second-grade students in the English Teacher Training Department. In order to measure the intercultural sensitivities of the students before and after the test procedure, the five-point likert type "Intercultural Sensitivity Scale" developed by Chen and Starosta (2000) and adapted to Turkish by Bulduk, Tosun and Ardiç (2011) was used as data collection tool. It is concluded that the curriculum of scientific research methods integrated with intercultural sensitivity development activities is effective in developing students' intercultural sensitivities.
