The Palgrave Handbook on Participatory Action Research with Children seeks to explore the diverse approaches to participatory action research (PAR) with children across disciplines and in various settings and contexts from around the globe. As interest in participatory action research with children grows, there is a need for more literature detailing the processes and approaches across its various stages. The Handbook offers insights from researchers across six continents coming from diverse academic and professional backgrounds at varying stages of their careers and experiences in conducting PAR with children. It focuses on the importance of children&s participation in research while taking into account their rights, diverse lived experiences and contexts, ethical considerations, power dynamics, social inequalities as well as acknowledging limitations and challenges. The chapters explore the possibilities of advancing methodologies and approaches to PAR with children, inclusive practices throughout the PAR process, relational and curricular impact of PAR with children, and the ethics, challenges and opportunities of conducting PAR with children in different settings with the support of or co-led by community-based organizations. This volume seeks to impress upon the reader that PAR with children can be empowering to everyone involved - adults and children - if done ethically, with adequate training and support, and with the active participation and involvement of children as researchers/co-researchers and co-creators of knowledge throughout the process.
