In this study, it was aimed to examine the impact of transformative learning theory on students' conflict resolution skill in social studies course. Embedded design, one of the mixed research methods, was used in the study. The participant group was formed by multi-stage mixed sampling method. The participant group included a social studies teacher and 51 students in the 5th grade. Conflict resolution skill scale, two semi-structured interview forms and unstructured observation were used to collect the data. Independent sample t-test and covariance analysis were used to analyse the statistical data, while content analysis was used to analyse the qualitative data. At the end of the study, it was found that transformative learning theory increased students' conflict resolution skills. The results also revealed that social studies courses conducted with transformative learning theory were seen by the participants as processes that confuse students' minds, surprise them, make them doubt, lead them to questioning and multidimensional thinking. It was also found that the participants thought that the courses provided students with various knowledge and values, encouraged them to research, analyse and synthesize, and act in a controlled manner. Depending on the results obtained, recommendations for education planners and researchers were developed.
