The purpose of this article is to provide an educational, theoretical, and methodological framework for using a special kind of action research, namely PALAR (participatory action learning and action research). This integrated methodology of lifelong action learning (AL) and participatory action research (PAR) has been developed over the past 25 years. It has been proven to be an effective approach to individual, professional, organizational, community (and generally practice) development. PALAR can be instrumental in pursuit of social justice and is well suited for both experienced and beginning researchers interested in researching and improving their own practice. The article illustrates with case examples how this framework has been put into practice for various programs in a variety of fields and countries. The PALAR framework is the basis for a generic program design, structure, and content, and for processes of learning, teaching, assessment, evaluation, and leadership development. It is a systemic and systematic program on how to design, justify, conduct, evaluate, write, and publish research that is particularly useful for community or work-based theses at master's, professional doctorate, and PhD levels. An original feature of this article is its comprehensive overview and summary of the theory and practice of PALAR for the first time, with references to further readings.
