The authors pursue three aims in this article. The first is to underscore critical praxis as an especially valuable approach to understanding and enabling teamwork. The second is to offer four dimensions of teamwork--vision, roles, processes, and relationships--as salient areas to interrogate using critical praxis. The third aim is to consider the implications and methods for teaching teamwork in the classroom context. In the process of doing so, the authors highlight limitations of prevailing theoretical approaches and note changes in their own practice of teaching and facilitating teamwork that have occurred through a commitment to critical praxis.
