Vygotsky suggests that successful learning, both for adults and children, is rooted in social participation and that learning takes place not in isolation, but with the assistance of others. The theory of andragogy also suggests that adults are task-centred and problem-centred in their approach to learning. In professional learning sessions, they bring a wealth of experience and practical knowledge that can serve as a valuable resource through the sharing of personal beliefs, practical challenges and success from their own classrooms. By expanding teacher conversations across schools, teachers can collaborate and learn from one another to enhance their professional growth and improve their practice.
