This project aims to gather empirical data on how assistive technology can support literacy and communication development in school-aged children with Angelman syndrome, in order to inform ongoing development of effective interventions for this population. Data gathered from this camp will contribute to the development of reliable evaluation models for students with Angelman syndrome. This camp provides an opportunity to field-test and refine existing assessment tools and to examine the role of assistive technology in more accurately assessing this population. We will evaluate students in the areas of phonological and phonemic awareness, developmental writing, and the use of symbols in communication. We will test the use of existing assessment tools such as early conventional literacy measures (e.g.: the QRI) and emergent measures, such as the Bridge Observational Rating Scales, the Developmental Writing Scales, Developmental Spelling Test, Pragmatics Profile, the Kovach AAC Profile, the Staugler Literacy Rubric, the Hanser 7 point rating scales, and more. Adults will be trained to self-assess their own support behaviors.
