This document provides an overview of design-based research (DBR) as a methodology for educational research. It discusses several key characteristics of DBR, including that it aims to develop theory through iterative design, implementation, and analysis of educational interventions in authentic contexts. The document also outlines typical stages in a DBR process, including developing potential solutions based on existing principles and innovations, implementing those solutions through iterative testing and refinement, and reflecting on how to further develop theories, principles, and solutions.
