Action unites with the research and it is the collective process of the self investigation. In all the way, each of the component is understood and the relative emphasis is receives nonetheless PAR theory to another. Constantinou (2009) says that PAR means participatory action research where the community consisting of the various people assemble together and the experience of them are shared in the manner that will give the root to the understanding of the facts and the circumstances.
