The purpose of this three-year long multiple qualitative case study was to explore and gain an in-depth understanding of the process of collaborative teaching as an alternative method of instruction in higher education. It was my intention to identify distinct stages of the process and depict issues involved in it. Comprehensive synthesis of acquired observations provides pedagogical and curricular insights for students, faculty, administrators, and broader academic community in the context of existing research. The collaborations were conducted by three teams of faculty members teaching in a major research university.
