Social communication deficits associated with Autism Spectrum Disorder are often exacerbated during adolescence. Group based approaches are effective intervention techniques for facilitating improved social communication skills in people with ASD; however, science, technology, engineering, and math activities, while highly preferred areas of interest, are overlooked as a therapeutic tool. This study determines the effectiveness of peer collaborations using a STEM activity on social communication for adolescents with ASD. Using solarbotics kits, peer dyads worked together over the course of a 12-week period to construct a functioning robot. Measures of social communication were collected prior to the initiation of the intervention, during the intervention, and after the intervention. Results indicated that the collaborative peer intervention using a STEM focused approach facilitated non-verbal and pragmatic improvements.
