This work aims at presenting the reader the common features that outline the concept of action research, not only to establish the basic elements that describe this research model, but also to establish a rough look that allows a critical review from the pedagogical stance in order to establish theoretical and practical tools that enable the construction of a scenario for their legal application. The approach for this study, besides being reflective, will tend to establish a dialectic confrontation between reality and communities so as to achieve a response in the practical experience of the researcher. To do so, two main topicswill be expounded: (i) action research: common elements for a critical discussion; and (ii) action-research applied to legal research.
