It is assumed that to appreciate a knowledge contribution in research-through-design, we all agree on what the act of designing is and should deliver in research. However, just from a glance at contributions in an HCI context, this is far from the case. The course is based on the book: Drifting by intention - four epistemic traditions in constructive design research authored by the instructors. It unpacks different ways of knowing in practice-based design and provides operational models and hands-on exercises applied on participants cases to help plan and articulate the contribution of design in each participant's individual research project.
