The purpose of this article is to explore the concept of empowerment, reframing it in critical terms and in a precise and useful way. I approach this exploration through two participatory action research studies. "Why are our teachers racist?" took place over an 18-month period from 2012 to 2014 at a mid-sized high school in a rural dairy town in Idaho with 52 Latino/a students and their white teacher. "Who can do research?" was conducted in the fall of 2013 with a group of 60 pre-service teachers at a large university in the Midwest of the United States. Through the application of lessons learned from these two studies, I frame critical empowerment as a process whereby historically marginalized and oppressed individuals and groups can potentially lay claim to power as they/we engage in participatory approaches to knowledge production, thereby gaining control over processes by which we as a society determine what is useful and valuable knowledge.
