Providing students with autism an appropriate education is a growing challenge. The prevalence of autism is increasing rapidly, with as many as 1 in every 150 children diagnosed with the disorder (Centers for Disease Control and Prevention, 2007). Recent federal mandates hold schools accountable for student achievement in math, language arts, and science, including students with disabilities (No Child Left Behind Act, 2002;Yell, Drasgow, & Lowrey, 2005). In addition, special education law requires that students with disabilities have access to and make progress in the general education (GE) curriculum (Individuals With Disabilities Education Improvement Act, 2004). As a result of these federal mandates, more students with autism and other disabilities are receiving their education in GE settings (U.S.
Department of Education, 2008).Yet much remains unknown about how adolescents with autism learn core academic skills in both general and special education settings. In large measure this is because of a notion that academic skill development is less crucial than functional skills curriculum for children with autism (Dunlap, Kern, & Worcester, 2001). Thus, studies of instructional strategies for academic content knowledge for children with autism are sparse. Furthermore, many children with autism are denied access to academic skills because they are perceived to lack the cognitive abilities or readiness skills needed for academic content instruction (Kliewer & Biklen, 2001;Mirenda, 2003). In addition, many children with autism do not follow a typical developmental sequence when developing academic skills, leaving teachers and families to believe that these children will not benefit from academic instruction (Kluth & Darmody-Latham, 2003). Despite these findings, a growing body of research has occurred in academic skill development for students with autism. For example, literacy development in people with autism has received growing research attention (Eikeseth &
