This article describes how preservice teachers accomplish and write up action research projects as part of their teacher preparation at one university in the United States. The paper is divided into four major sections. In the first section, the instructor describes how teacher research is introduced to teacher education students and how they are guided through the processes of conceptualizing, doing, and writing up their projects. The next two sections are the stories of two 1st-year teachers who describe and reflect on what they learned from completing action research projects under the direction of the instructor. The concluding section offers generalizations that synthesize lessons learned by the authors.
