Enhancing Orthographic Communication and Literacy Outcomes for AAC Learners
Enhancing Orthographic Communication and Literacy Outcomes for AAC Learners: Investigating Effective Instructional Strategies
Source: ClinicalTrials.gov · Last updated 3 Feb 2026
Brief summary (registry, in English)
The goal of this clinical trial is to determine whether adding Integrated Decoding and Encoding instruction to the ALLSTAR literacy program improves reading outcomes for students with significant literacy and communication needs. The study will also examine how students' reading skills change over time across instructional conditions. The main questions it aims to answer are: Do students who receive ALLSTAR with Integrated Decoding and Encoding instruction demonstrate greater improvements in literacy outcomes than students who receive ALLSTAR as standard care alone? How do students' literacy skills change from baseline to mid-intervention and post-intervention across the two instructional conditions? Researchers will compare two groups using a randomized controlled trial design. One group will receive 60 lessons of ALLSTAR as the standard of care (ALLSTAR-SC), and the other group will receive 60 lessons of ALLSTAR with the addition of Integrated Decoding and Encoding lessons (ALLSTAR-I\*). Literacy outcomes will be measured using repeated assessment probes at baseline (0 Lessons), after 30-40 lessons, and after 60 lessons to evaluate differences between groups and changes over time in the individuals.
