This applied doctoral course introduces educational leaders to inquiry as a leadership practice, drawing on principles of action research and insider inquiry. The course emphasizes how leaders examine and respond to complex problems of practice within their own organizational contexts through cycles of reflection, evidence, and action. Students explore foundational concepts such as scholar-practitioner identity, knowing-in-action, positionality, ethics, and organizational context as they relate to leadership decision-making. Rather than focusing on implementation, the course centers on the design of an action-research-informed leadership inquiry that is responsive to context, values, and organizational dynamics. Through engagement with scholarly literature, applied examples, and peer dialogue, students develop a structured inquiry plan that prepares them to lead thoughtful, ethical, and evidence-informed change.
