Nowadays, there is a growing interest in transdisciplinary approach to university curriculum development. Transdisciplinary studies are about the realms and goals of the transition field. The early phases of transdisciplinary in higher education curriculum can be complex and so there are challenges to defining and operationalizing this approach to the university curriculum. In this paper, with respect to the different perspectives on the subject, the conceptual framework and the model of the curriculum based on the causal layered learning are explained and the challenges and obligations of the subject are conceptualized based on four different types of curricular issues: philosophical and pedagogical considerations, issues and responsibilities affecting the teaching process, issues and responsibilities affecting students learning, issues and responsibilities affecting course design and issues and responsibilities affecting learning assessment. In the end, it has been pointed out that curriculum, teaching and learning in higher education encompass a range of institutional adjustments and adaptations that are not easily adaptable and structured within the framework of current situation, thus it is very useful to address obligations and responsibilities in designing a course of study, curriculum goals, and evaluation and preparation of students to face the challenges posed by new forms of curriculum.
