This paper considers long-standing concerns about research/theory practice gaps in kinesiology, and proposes one potential solution. An analysis of the problem is followed by an overview and illustration of a new translational research mechanism: pedagogical cases (Armour, 2014). This mechanism has been designed to support the training and career-long development of practitioners in the broad field of physical activity education (PAE). It is argued that PAE practice is always interdisciplinary, therefore researchers in the kinesiology sub/disciplines have a responsibility to collaborate across disciplinary boundaries to develop new, interdisciplinary knowledge that meets the needs of practitioners. It is also argued that researchers and practitioners have a responsibility to work together to do the difficult synthesis work required to improve both research and practice.
