An increasing challenge for many secondary special education teachers is preparing students for the writing demands in postsecondary settings. The self-regulated strategy development (SRSD) model of writing instruction, considered an evidence-based practice, is an effective strategy for enhancing the writing skills of students with disabilities, such as learning disabilities or behavioral disorders, at the secondary level. This article discusses the flexibility and practicality of the SRSD model by describing ways in which secondary teachers can effectively use this strategy to enhance the argumentative writing skills of their students in English language arts, science, history, and mathematics and to teach students how to self-advocate through writing. Information about supports, materials, and other resources for teachers to utilize are included.
