Interdisciplinary learning improves cognitive skills and increases motivation for learning and teaching in higher education. Interdisciplinary education, which requires the collaboration of different disciplines, contributes to the development of students by integrating disciplinary knowledge and providing a multidimensional perspective. Thus, interdisciplinary education has become an alternative approach to discipline-centered education in higher education. Interdisciplinary learning is necessary for postmodern life because it eliminates the limitations of disciplinary education. The complex nature of the problems posed by postmodern life requires the collaboration of many disciplines. Current political, economic, social, religious, and legal issues are too complex to be solved from the perspective of a single discipline. Discipline-centered education may not be sufficient to provide solutions to current problems or to equip students with problem-solving skills. For this reason, this study reveals that interdisciplinary learning, which is increasing in higher education, can also be applied to higher religious education. The purpose of this study is to demonstrate the outcomes of interdisciplinary learning in higher religious education through a sample training. In the academic year 2023/2024, an interdisciplinary training was conducted on the common problems of theology and other disciplines, and the results were revealed through the views of 16 participants. The research was conducted as a case study by using the qualitative research method, and the research data were coded under four themes: (1) need for interdisciplinary learning in higher religious education, (2) disciplines associated with higher religious education, (3) outcomes of interdisciplinary learning, and (4) suggestions for interdisciplinary education. According to the research findings, the participants believe that courses in higher religious education have interdisciplinary content, that interdisciplinary education is necessary in higher religious education, and that interdisciplinary learning contributes to personal and professional development. It is recommended that studies be carried out using alternative approaches to improve higher religious education.
