Action research: what, why and how?

Action research is a form of research that enables practitioners to investigate and evaluate their own work. It is increasingly used in health care research; it is a research strategy in which the researcher and practitioners from the setting under study work together in projects aimed at generating new knowledge and simultaneously improving practice. This article gives an overview of the theoretical background of action research, its international historical development and explanations of its varied forms and related practical applications. Ethical problems are discussed as are questions of rigour The article shows that action research can be used to bridge the gap between theory and practice by generating knowledge fitting the particular circumstances in the practical setting, thereby avoiding problems of implementation of research findings due to lack of fit or lack of motivation. Action research lastingly increases the capacities of practitioners to solve problems encountered in practice.
