This paper presents a theoretical model describing processes involved in a collaboration between education and research actors. The epistemological nature of collaborative research is presented to set up the model. The design-based research methodology aims at achieving theoretical and pragmatic production objectives. The suggested model aims to create a better understanding of the processes at work in collaborative research by describing the contribution of each actor as a representative of his/her institution, while addressing the complex aspects of collaboration that go beyond the sum of individual contributions The discussion focuses on the limitations of the model and on the articulation of the following concepts: boundary object, praxeologies, participation, negotiation, valuation, and brokering.
