The purpose of this conceptual replication study was to investigate the efficacy of an early literacy intervention when it was implemented by special educators in general education classrooms with students in the class participating in the lessons. The study was conducted in 16 schools in three states. Eighty students with severe disabilities participated in the study. Students in the intervention group received Early Literacy Skills Builder (ELSB) instruction, and students in the "business-as-usual" control group received literacy instruction planned by special education teachers to address the students' individualized education program literacy goals. Literacy assessments were conducted in five waves scheduled across the school year. Results showed that students receiving ELSB instruction made greater gains in assessed literacy skills than students in the control group. These findings provide evidence that students with severe disabilities can benefit from comprehensive emergent literacy instruction when it is implemented in general education settings.

This study evaluated the effectiveness of a multicomponent early literacy curriculum that included phonics and phonemic awareness in comparison to a sight word approach. A total of 93 students with severe developmental disabilities who were enrolled in Grades K through 4 were randomly assigned to either a multicomponent early literacy curriculum or a sight word comparison curriculum. The instructional interventions were implemented over an academic school year. Results indicated that students in the multicomponent early literacy curriculum had significantly higher mean literacy scores than the students in the sight word condition, with small to moderate effect sizes (0.30-0.49). Further analysis indicated that phonics skills appeared to contribute most to the differences between the two curriculum approaches. Implications for teaching decoding skills, one of the components needed for students to become fully literate, are discussed. (Contains 3 tables and 1 note.)

This study evaluated the impact of a curriculum called the Early Literacy Skills Builder on the language and early literacy skills of students with significant developmental disabilities. Students in the control group received the ongoing sight word and picture instruction prescribed by their individualized education programs. Results indicate statistically significant interaction effects for the treatment group for two research team-designed measures of early literacy (the Nonverbal Literacy Assessment and a pretest/posttest for the experimental curriculum). Significant interaction effects were also found for two standardized measures (Peabody Picture Vocabulary Test III and Memory for Sentences of the Woodcock Language Proficiency Battery). Implications and future research needs are provided.
