In this paper, action research is explored as a process for professional learning and collaboration among post secondary teachers. Qualitative data from reflective journals maintained by instructors who taught multiple sections of a masters research course over a two-year period informed the exploration of responsive pedagogy. Action research is discussed as a methodology used by instructors to reflect on practice in order to engage in continuous quality improvement of learning in higher education. The authors share how action research proved to be a valuable methodology used to guide this reflective experience and can be used to inform ongoing instructional design processes and future research.
