This article argues for a scholarly research agenda in the Scholarship of Teaching and Learning (SoTL) for the broad discipline of professional communication by distinguishing SoTL from other types of teacher-scholar practice, including anecdotal publications, action research, traditional educational research, and scholarly teaching. Doing so carefully positions SoTL as an extension of the pedagogical roots of business and technical communication and as a way to reinforce our teaching fortes, unite the fields within the discipline via research, and strengthen arguments for disciplinarity and academic respect.
