This study explores how teacher leadership develops in virtual communities of practice (vCoPs), focusing on the roles of teacher agency and distributed leadership. Using a phenomenological approach with semi-structured interviews, the research highlights the importance of vCoPs in fostering teacher leadership through collaborative learning and shared expertise. Teacher agency enables educators to take initiative in their professional development, while distributed leadership allows teachers to assume leadership roles regardless of formal positions. These two concepts work together to create a supportive environment that encourages collaboration, innovation, and professional growth. The study found that vCoPs provide opportunities for teachers to share resources, collaborate on projects, and develop professional networks, all of which contribute to the development of teacher leadership. Teachers in vCoPs are seen as active participants who take on leadership roles, support colleagues, and contribute to school improvement. The study also emphasizes the importance of teacher agency in promoting self-directed professional development and collective leadership. Distributed leadership is shown to break down traditional hierarchies, allowing for more inclusive and collaborative decision-making. The findings suggest that vCoPs are effective platforms for teacher leadership, offering a flexible and accessible environment for professional growth. The study concludes that teacher leadership in vCoPs is a dynamic and collaborative process that benefits both educators and students.This study explores how teacher leadership develops in virtual communities of practice (vCoPs), focusing on the roles of teacher agency and distributed leadership.
