This paper examines the potential for teachers to act as researchers within their own classrooms. It utilizes a four-step process for such classroombased research: observation, reflection, planning, and action. The focus of the research described is the creation of a Communicative Writing Framework (CWF) to aid in the examination and evaluation of linguistically diverse children’s writing. Research by James Cummins, Katherine Perera, and Linda Flower provide the theoretical basis for such a framework. Application of the CWF is made to (a) data from the Language Assessment Scales-Writing, a national assessment tool, and (b) writing activities of students in a first-grade Spanish-English bilingual classroom. Suggestions are provided for teachers interested in implementing and adapting the CWF model to their own writing classes.
