Current research aiming to understand the gaps between research and practice in K-12 education often overlooks the importance of grasping the indirect relationships that develop between research and practice communities via the various people and organizations positioned to serve as knowledge brokers. The purpose of this study is to understand both how research brokerage by such individuals and organizations can lead to research use and how knowledge brokers can be leveraged to better support research use in practice. Specifically, this study aims to identify what happens in the space between research and practice by using qualitative methods to explore three areas of inquiry: (1) understanding which individuals and organizations serve as knowledge brokers, (2) understanding the types of research-based products that move through brokerage systems and how research-based products are transformed in that system, and (3) understanding the paths by which information moves from research into practice. To better understand what occurs between the production of research findings and their ultimate use, the authors focus on the set of actors, activities, motivations within which research is exchanged, transformed, and otherwise communicated--that is, the dynamic and complex phenomenon of brokerage. This body of work utilizes backward tracking case studies and examines the brokerage process through a five-step approach to produce credible stories of what happens as research moves between research and practice.
