There has been growing discourse related to the importance of the scholarship of educational development (SoED), but less discussion related to clearly defining principles for guiding engagement in SoED or contextualizing SoED within literature related to the scholarship of teaching and learning (SoTL). Expanding upon Felten's (2013) principles for SoTL, as well as evolving discourse related to principles of educational development (e.g., Gibbs, 2013; Taylor & Rege Colet, 2010; Timmermans, 2014), this paper presents seven principles for SoED. Two additional principles (transforming practice and reflective practice) are added to Felten's principles to further contextualize SoED in relation to educational development and SoTL. Three cases are provided to illustrate educational development, SoTL, and SoED within the context of these principles. The interrelationships between educational development, SoTL, and SoED are complex. While SoED offers many opportunities for further legitimizing the individual and collective practices in educational development, it also presents many additional tensions and questions for further research.
