This account identifies some of the tensions that became apparent in a large interdisciplinary technology-enhanced learning project as its members attempted to maintain their commitment to responsive, participatory research and development in naturalistic research settings while also "enacting" these commitments in formal research review processes. It discusses how these review processes were accompanied by a commitment to continuing discussion and elaboration across an extended research team and to a view of ethical practice as an aspect of "phronesis" or "practical wisdom" which demands understanding of specific situations and reference to prior experience. In this respect the interdisciplinary nature of the project allows the diverse experience of the project team to be brought into play, with ethical issues a joint point of focus for continuing interdisciplinary discourse.
