In this dissertation study, I examine the writing development of five culturally and linguistically diverse (CLD) students in an elementary classroom, where English is the language of instruction. Interest in written literacy for monolingual and bilingual learners has increased as a result of high-stakes testing, No Child Left Behind, and state adoption of the Common Core Standards. Additionally, National Assessment of Educational Progress (U.S. Department of Education, National Center for Education Statistics, 2007) shows that CLD students score significantly lower on writing performance tasks than their mainstream English-speaking Caucasian peers. This study seeks to better understand the process by which CLD students develop the specific characteristics of procedural and persuasive writing given the instruction in these genres.

This year-long qualitative research study used a multiple case-study design (Hancock & Algozzine, 2006; Merriam, 1998) and included classroom observations, videotaped examples of the nexus between classroom instruction and student writing, the collection of students' writing samples, student interviews, and formal and informal teacher interviews. For this study, I followed one fifth-grade teacher and five of her students as they worked on the two genres. Guided by systemic functional linguistic theory—a linguistic theory that reveals features that encase cultural and social expectations, making the language demands of schooling explicit—the analysis examined students' writing development in the two genres, the context and process of their development in the genres, and an in-depth examination of the impact of the context and process on their procedural and persuasive writing pieces.

The results suggest that CLD students' writing development is multifaceted and complex. CLD students' writing development of procedural and persuasive writing was mediated by interrelated factors: the individual student, the peers, the teacher, and the texts themselves. I discuss the role of each of the mediating factors and argue for adopting a model of writing that incorporates a combination of genre- and process-writing theories with a particular understanding of the unique nuances pertinent to CLD students.
