Rethinking collaborative learning through participation in an interdisciplinary research project: tensions and negotiations as key points in knowledge production.

As social and cultural psychologists of learning, we are persuaded of the crucial role of interaction in development and learning. But how do we experience this assumption in our own research practices and in our collaboration with colleagues? Taking as our object of study our own participation in a European Research and Development project that aimed to enhance interactive and argumentative skills in learning settings, this study shows how collaboration among project partners is not something that is to be taken for granted, but something that is elaborated and evolves in time, takes diverse forms, and is mediated by multiple tools. The psychological processes--more particularly tensions and negotiation--involved in collaboration are developed and discussed. The study explores the processes of establishing collaboration and, through the analysis of specific zones of tensions, sheds light on the way new knowledge (on how to do research, how to communicate, how to work together) is constructed. It contributes to the understanding of the issues and conditions for the development of a community of practice.
