This book presents a guiding framework for designing and supporting participatory research with young children. The volume shares detailed approaches to research designs that support collaborative work with young children and teachers in a wide range of early learning environments. It presents conceptual and ethical considerations for participatory work, and explores children's agency through engagement in participatory practices. It examines challenges to accepted practices and understandings of young children, and discusses the analysis and dissemination of participatory work with children. In doing so, the book informs readers about the conceptual understandings and methodological approaches that can be used to support participatory research investigations where the young child is viewed as knowledgeable and capable of sharing unique opinions, interpretations, and understandings of her experiences as embedded within social, cultural, and political worlds. The book sets the stage for early childhood researchers and educators to develop new understandings grounded in post-developmental, critical, and social constructivist theories while exploring supportive methodological approaches.
