This article reports an action research study that examined the Leadership Study Group, one learning activity designed to build knowledge and skills for aspiring school leaders and implemented in a six-credit introductory course for school leader certification. Through analysis of a variety of qualitative data collected over nine semesters, I assessed the value of this instructional module, reviewed the effectiveness of iterations, and determined the need and type of additional modifications to further students' leadership efficacy. This study, which informed my practice, highlighted the strength of this activity in promoting reflective behavior and developing team-building capability as well as led me to research additional strategies and instructional materials to enhance this experience. This study is also offered as a stimulus for professors of leadership to conduct action research to evaluate and improve other student-centered learning activities for emerging leaders.
