In this article, we demonstrate how Legitimation Code Theory (LCT) can be enacted to explore the nature of Scholarship of Teaching and Learning (SoTL) in higher education. Specialization and semantics from LCT are applied to define SoTL practice and map cumulative knowledge building processes. As members of the Faculty Development Committee (FDC), we enact LCT tools to conceptualize our professional development. We provide SoTL narratives as well as vignettes depicting how LCT led to positive transformative learning. The article concludes that LCT tools, with their explanatory power, can be utilized to form highly effective components of a faculty development program.
