The paper summarizes the political economy of knowledge production in
an increasingly privatized, postindustrial world of knowledge society.
This analysis is linked to the emergence of participatory research mo
vements. It argues that the participatory approach to community resear
ch offers epistemology and methodology that address people, power and
praxis in our postmodern, information society. The paper then describe
s how a participatory research project is carried out in community pra
ctice, articulating key moments and the roles of the researcher and pa
rticipants. In order to develop this understanding further it examines
the efforts of two specific projects and shows how knowledge producti
on can serve as a conceptual entry point in community organizing throu
gh which people make choices, shape action, and create social movement
s.
