Abstract: | Proficiency in letter–sound correspondence is important for decoding connected text. This study examined the effects of an evidence-based intervention, incremental rehearsal (IR), on the letter–sound expression of three kindergarten English language learners (ELLs) performing below the district benchmark for letter–sound fluency. Participants were native speakers of Hmong, Spanish, and Polish. A multiple-baseline design across sets of unknown letter sounds was used to evaluate the effects of IR on letter–sound expression. Visual analysis of the data showed an increase in level and trend when IR was introduced in each phase. Percentage of all non-overlapping data (PAND) ranged from 95% to 100%. All participants exceeded expected growth and reached the spring district benchmark for letter–sound fluency. Results suggest that IR is a promising intervention for increasing letter–sound expression for ELLs who evidence delays in acquiring letter sounds. |
