The use of augmentative and alternative communication by children with developmental disability in the classroom: a case study

Abstract

Purpose Augmentative and alternative communication (AAC) systems are often introduced to children with disabilities who demonstrate complex communication needs. As attending school is an essential part of these children’s lives, it is important that they use their AAC system to communicate in the classroom. This study aimed to describe the nature of the use of AAC by students with developmental disabilities in the classroom. Materials and Method This study was conducted in Malaysia. Six students were observed twice each in their classroom and their classroom interactions were video recorded. The video recordings were transcribed and coded for the presence of a communication event, the student’s mode of communication and communication function, the communication partner involved, and access to the AAC system. Results Contrary to past studies, most students in this study spontaneously initiated interaction almost as many times as they responded. They primarily communicated with gestures and verbalizations/vocalizations despite having been introduced to an AAC system. When students communicated using their AAC system, they mainly interacted with the teachers, and for the function of either behavioral regulation or joint attention. It was found that for 39% of communicative events, the student’s aided AAC system was not within arm’s reach. Conclusion The findings highlight the need for efforts to encourage students with complex communication needs to use AAC more frequently in their classroom to be able to communicate more effectively and for a wider range of communicative functions. Speech-language pathologists can work closely with teachers to provide the necessary support to these students.
