Cooperative inquiry, also known as collaborative inquiry was first proposed by John Heron in 1971 and later expanded with Peter Reason. The major idea of cooperative inquiry is to “research ‘with’ rather than ‘on’ people.” It emphasizes that all active participants are fully involved in research decisions as co-researchers. Cooperative inquiry creates a research cycle among four different types of knowledge: propositional knowing (as in contemporary science), practical knowing (the knowledge that comes with actually doing what you propose), experiential knowing (the feedback we get in real time about our interaction with the larger world) and presentational knowing (the artistic rehearsal process through which we craft new practices). The research process iterates these four stages at each cycle with deepening experience and knowledge of the initial proposition, or of new propositions, at every cycle.
