Interventions

  • ALL Phonics Instruction — BEHAVIORAL
    The Accessible Literacy Learning (ALL) App is available in the app store and created by TobiiDynavox (an AAC device company). The ALL app is evidence informed and includes pre-made lessons in early phonics/phonological skills including: letter-sounds, sound blending, decoding, phoneme segmentation, sight words, and encoding. The materials made in the app are adapted and created for children with minimal or no speech.
  • ALL Sight Word Instruction — BEHAVIORAL
    The Accessible Literacy Learning (ALL) App is available in the app store and created by TobiiDynavox (an AAC device company). The ALL app is evidence informed and includes pre-made lessons in early phonics/phonological skills including: letter-sounds, sound blending, decoding, phoneme segmentation, sight words, and encoding. The materials made in the app are adapted and created for children with minimal or no speech. This group will only use the sight word lessons, as well as the library for sight word books. No phonics instruction will be provided through the app.

Study Details

The goal of this clinical trial is to test a phonics-based literacy program for children with limited or no speech who use augmentative and alternative communication. More specifically, this study aims to: 1. Understand if using a literacy app (Accessible Literacy Learning) created to support individuals with limited or no speech, with instruction provided by a service provider, will increase their literacy skills 2. Understand how many trials/how much time it takes to acquire each of the 6 early literacy skill assessed 3. Understand if service providers think the Accessible Literacy Learning app is appropriate for this population that needs many literacy adaptions due to challenges with speech. 4. Understand if any characteristics lead to more learning of the skills, for example, diagnosis or age Participants will be asked to complete 100 lessons using the app. The lessons will be phonics-based for the intervention group. The comparison group with use the same app and complete 100 lessons, but will only complete lessons in sight word (no phonics).

Arms

  • Experimental: ALL Phonics Instruction
    Lessons for the treatment group will be 30-min. long using the ALL app with a known service provider. Lessons will include systematic instruction with four subskills per session (e.g., letter-sounds, sound blending, typing, and sight words). The words and subskills with rotate based on the data collected and the machine learning within the technology. The child will complete 100 lessons. The systematic instruction with subksills (e.g., sound blending, decoding) includes 10 trials per word and an instructional sequence that introduces the skill, two models, six trials of guided practice, and two trials of independent practice with corrective feedback.
  • Active Comparator: ALL Sight Word
    Lessons for the comparison group will be 30-min. long using the ALL app with a known service provider. Lessons will include systematic instruction with sight words. The child will also complete 100 lessons.No phonics instruction will be provided to this group through the ALL app.
