While participating in the Bilingual Teacher Research Forum (a teacher inquiry group), I decided to do research in my classroom to investigate the ways in which emergent bilinguals (EBs) expanded their appreciation and understanding of writing in English as a second language. The purpose of this study was to examine and describe first-grade EBs' development of writing. A variety of assessment tools were used to document students' writing growth over time. All the children made progress both in their spelling and in their writing of stories. Engaging in teacher-based research became a professional development tool to document and reflect on my teaching practice and its impact on the writing attitudes and skills of a group of first-grade EBs.
