These authors emphasize in this quotation the diversity of paradigms and the difficulty of defining qualitative research. A first observation that can be made is that researchers using qualitative methodology study social reality in its immediate context, and as it becomes, are trying to get the meaning and interpretation of the reality studied from the own of the protagonists of a determined social interaction meanings. Participatory research is an activity that combines, how to interrelate the research and actions in a particular field selected by the researcher, with the participation of the subjects investigated. The ultimate goal of this type of research is the search for changes in the community or population to improve living conditions. For example, the Choke researcher, infiltrates a group of tribes Ashaninkas to learn their customs, and thus able to observe the kind of daily life that occurs in this population. To do this he will have to put aside all their everyday ways of acting and will need to adapt to population. Gathered once the necessary data by observing Choke will seek the way to capture the kind of life that there has occurred, seeing their way of how you face the Ashaninkas daily life, and if somehow you could improve.
Also he will provide, through its research, some aid to the same techniques. Action research has similarity with the participatory, there currently are talk quite often participatory action research. It is one of the attempts to summarize the relationship of identity required to construct a theory that will be effective as a guide for action and scientific production, which is closely linked to the Science for the transformation and social liberation. It has a more striking style to research linked to education called diagnostic evaluation criteria. Ethnography examines the facts such as they occur in the context, historical and educational processes, socio-cultural changes, functions and roles of the members of a given community. It is characterized by the use of observation, whether participant or not. In either of these options observation attempts to register, as far as possible, what happens in the place that is being considered, making use of instruments to supplement the information obtained by observation.
