Modes of collaboration are gendered in the sense that they define power relationships among members of a group. In this study, the authors define three collaborative modes: dialogic, asymmetrical, and hierarchical. Dialogic and asymmetrical modes are emancipating and characterized by flexibility, open-ended inquiry, and concern for the growth and development of the individuals involved. Hierarchical modes are oppressive and are characterized by rigidity and suppression of the voices of others in the group. Two collaborative writing groups in a chemical engineering design course exemplify these modes. The first, composed of two women and two men, was primarily dialogic, and the second, composed of two women and three men, exhibited characteristics of all three modes.
