Action research is a participatory approach that is used in an array of contexts. From its first proposition it comprises four core principles: participation and collaboration; a constant spiral cycle of self-reflection; knowledge generation; and practice transformation. Praxis and emancipation are two important analytical categories in AR, but are conceptualized differently in the two existing AR traditions. These conceptualizations reveal different AR aims, which lead to either the use of AR as a method (Northern tradition) or as a methodology (Southern tradition). Much depends on the researchers’ interest and worldview. Our objective in this paper is to compare how emancipation and praxis are theorized in both traditions. This discussion intends to add insight into the methodological understanding and utilization of AR.
