In this article, Walt Haney, Michael Russell, and Damian Bebell summarize a decade of work using student drawings as a way to both document and change education and schooling. After a brief summary of more than one hundred years of literature on children's drawings, the authors point out that drawings have been little recognized as a medium of educational research in recent decades. Next they explain how the work reported here has evolved, recounting how they have used student drawings as a way to document educational phenomena. They then present reliability and validity evidence to support such use on a macro level. The authors go on to relate examples at the micro level of how drawings have been used to inform and change education and learning. Finally, they argue that student drawings, though only one form of inquiry, help illustrate the fundamental point that, if educational reforms are to succeed, we must treat teachers and students not just as the objects, but also as the agents, of reform and improvement.
