Augmentative and Alternative Communication in the Classroom: Teacher Practices and Experiences

Leveraging Communication Partner Speech to Automate Augmented Input for Children on the Autism Spectrum Who Are Minimally Verbal: Prototype Development and Preliminary Efficacy Investigation

PURPOSE

Augmentative and alternative communication (AAC) technology innovation is urgently needed to improve outcomes for children on the autism spectrum who are minimally verbal. One potential technology innovation is applying artificial intelligence (AI) to automate strategies such as augmented input to increase language learning opportunities while mitigating communication partner time and learning barriers. Innovation in AAC research and design methodology is also needed to empirically explore this and other applications of AI to AAC. The purpose of this report was to describe (a) the development of an AAC prototype using a design methodology new to AAC research and (b) a preliminary investigation of the efficacy of this potential new AAC capability.

METHOD

The prototype was developed using a Wizard-of-Oz prototyping approach that allows for initial exploration of a new technology capability without the time and effort required for full-scale development. The preliminary investigation with three children on the autism spectrum who were minimally verbal used an adapted alternating treatment design to compare the effects of a Wizard-of-Oz prototype that provided automated augmented input (i.e., pairing color photos with speech) to a standard topic display (i.e., a grid display with line drawings) on visual attention, linguistic participation, and (for one participant) word learning during a circle activity.

RESULTS

Preliminary investigation results were variable, but overall participants increased visual attention and linguistic participation when using the prototype.

CONCLUSIONS

Wizard-of-Oz prototyping could be a valuable approach to spur much needed innovation in AAC. Further research into efficacy, reliability, validity, and attitudes is required to more comprehensively evaluate the use of AI to automate augmented input in AAC.

Identifying Implementation Strategies to Increase Augmentative and Alternative Communication Adoption in Early Childhood Classrooms: A Qualitative Study

PURPOSE

The goal of this study was to identify promising implementation strategies that may increase teachers' and speech-language pathologists' (SLPs) adoption of augmentative and alternative communication (AAC) during routine classroom activities.

METHOD

A grounded theory approach was used to collect and code online, semistructured interviews with six special education teachers and 14 SLPs who taught children aged 3-8 years who used AAC in inclusive and self-contained special education classrooms. Interviews were transcribed and coded verbatim using the constant comparative method. During a member checking process, six participants (n = 30%) confirmed their transcripts and commented on emerging themes.

RESULTS

Participants shared a range of implementation strategies to increase AAC use during typical classroom activities, which were organized into seven themes: distribute modern AAC equipment, provide foundational training, share video examples, develop a systematic plan for adoption, deliver practice-based coaching, alter personnel obligations to provide protected time, and connect with professionals. A preliminary thematic map was created to link implementation barriers, strategies, and potential outcomes.

CONCLUSIONS

AAC interventions effective in clinical research can be difficult to translate into routine practice unless investigators directly explore the needs of and demands on educational professionals. Future research should define implementation strategies clearly, solicit feedback from school-personnel, and match implementation strategies to the needs of local schools to support the uptake of AAC interventions in routine classroom settings.
