Educational Design Research (EDR) is an emerging approach that attempts to bridge the demand for rigorous research with the development of relevant solutions to educational problems, particular those that involve technology. EDR constitutes a family of design-oriented approaches to educational research, including but not limited to design-based research, design and development research, and design-based implementation research. The purpose of this special issue is to advance EDR by showcasing exemplars of high quality design-oriented research in technology-supported post-secondary educational settings.
