Design-based research seminar for the Schwartz Wieman Lab Uber Meeting (SWLUM), Stanford University. The discussion centred on key topics in design-based research and the learning sciences, with participants examining how to design bespoke solutions to meet the local requirements of diverse learning settings, but as design-based researchers, aiming to contribute also to the broader knowledge base of principled, systematic design in the learning sciences.
