Theoretical Foundations

This project draws on research on learning disabilities and adult literacy development, particularly studies examining the cognitive and linguistic processes involved in reading and writing. According to Improving Adult Literacy Instruction: Options for Practice and Research (National Research Council, 2012), many adolescents and adults experience difficulties with core literacy processes such as decoding, reading fluency, comprehension, and written expression. These challenges are often associated with learning disabilities, a group of developmental conditions that affect the acquisition of specific academic skills.

Learning disabilities do not reflect low intelligence or lack of motivation. Rather, they involve unexpected difficulties in learning particular skills, especially reading and writing, despite adequate intellectual ability and educational opportunities (Fletcher et al., 2007; Gregg, 2009). Research also suggests that these difficulties are influenced by complex interactions among cognitive, linguistic, neurobiological, and environmental factors (Grigorenko, 2009; National Research Council, 2012). Importantly, advances in neuroscience show that the brain retains a degree of plasticity, meaning that effective instruction and targeted interventions can support literacy development even in adolescence and adulthood (Shaywitz, 2003; Pugh et al., 2010).

Among the different types of learning disabilities, reading disabilities are the most prevalent, affecting a large proportion of individuals identified with learning difficulties (Lyon et al., 2001; Kavale & Reese, 1992). These challenges typically involve weaknesses in decoding, reading fluency, and comprehension, often linked to difficulties in phonological processing, language development, working memory, and metacognitive strategies (Swanson & Siegel, 2001; Berninger et al., 2006).

One instructional strategy that has proven beneficial for learners who struggle with comprehension is the use of story maps. Story maps visually organize the key elements of a narrative—such as characters, setting, conflict, events, and resolution—helping readers recognize the underlying structure of a story. Research suggests that graphic organizers like story maps can improve comprehension, support recall, and help learners better understand relationships between events within a narrative (Idol, 1987; Kim, Vaughn, Wanzek, & Wei, 2004). By making narrative organization explicit, story maps support comprehension and encourage deeper engagement with texts.

Together, research-based instruction, structured supports, and strategies such as story mapping can help learners develop stronger reading and writing skills and participate more fully in meaningful literacy experiences.
