This design-based investigation displays how nurse educators could design and implement a debriefing procedure to facilitate students' clinical reasoning skills and how students could learn from this. This method integrates research, innovation and collaboration. The design and enactment under real-life hospital conditions generated design principles for educators and researchers which may be useful for those seeking to improve teaching and learning clinical reasoning in practice. More clarification is needed about the path from design through enactment to real change in practice.
