La ricerca azione: questioni epistemologiche e di metodo

The chapter analyzes the methodological principles that characterize and define action research and discusses how these principles have been differently applied within the various approaches to action research. It is argued that these differences are due to different assumptions about the nature of reality and the possibility of the researcher to know this reality.
