Effective management is the foundation from which learning can occur. In addition to its impact on student learning, the ability to manage effectively is an important factor in teacher job satisfaction. Management struggles have been linked to teacher stress and burnout and to an inability to care about students. In this study, the authors attempted to address the lack of available research on pedagogical knowledge from teachers' perspectives. The specific research questions that guided this study were: (1) What do elementary physical education teachers know about management?; and (2) How was that knowledge gained, and did the knowledge of elementary physical education teachers change over time? Understanding what teachers know and how they know it should provide insights into preservice education and inservice education. With better insights into teacher knowledge bases, teacher educators, researchers, and administrators can improve professional development plans to better meet teachers' needs. Improved teacher management would then likely lead to increased learning opportunities for students.
