A Formative Evaluation Of Augmentative And Alternative Communication Approaches To Promote Literacy In Young Children With Severe Speech And Physical Impairments

Abstract

This thesis describes an educational intervention with three children with severe speech and physical impairments. The intervention focused on storybook reading experiences for early literacy development through the use of Augmentative and Alternative Communication technologies and methods. The review of literature focused on the main aspects relating to children with SSPI, and in particular on the difficulties they experience in developing emergent literacy skills. This review suggests the hypothesis that the use of AAC Techniques in storytelling achievement can provide emergent literacy experiences, which can promote the development of literacy in children with SSPI. In particular the study set out to enquire whether AAC techniques can be used to enhance participation with SSPI in storytelling activities, and whether such activities improve a pupil’s opportunities to become emergent readers. A six-month intervention was designed which included strategies proposed for increasing the children’s participation during storybook reading sessions, like repeated readings of the same story, abundant use of graphic symbols and access to AAC techniques. Qualitative data were gathered from the professionals at the Centre, and from the mothers. Storybook reading sessions with the teacher at school and with the mothers or significant other at home were videotaped, at the beginning and at the end of the intervention. Quantitative data were collected by videotape analysis. Communicative acts of children and adults were divided into communication categories, and their meaning was discussed as to form, use and content. One of the main conclusions of the study was that the use of stories promoting communication and language learning in storybook reading sessions can develop literacy skills if carried out in conjunction with AAC techniques, including graphic symbols and the technology to generate them. A second conclusion is that there is no automatic transfer of the improvement of communicative skills in the classroom to the interaction with the mothers
