This study explores the processes occurring during technology workshops which built on interests and enhanced social engagement for students with autism spectrum disorders (ASD). The workshops used a community based research design and focused on teaching a creative three-dimensional (3D) design programme (SketchUp™) to students with ASD. Seven boys (ages 8-17) participated in this pilot programme over a 6-month period. The methodology was a qualitative thematic analysis of videotapes and transcripts of workshop sessions. The two key themes that emerged were: (1) development of authentic peer relationships through humour, common interests, physical actions, and playful competition; and (2) the importance of a scaffolded learning environment with support from peers and an adult mentor, as opportunities for social engagement. These findings indicate that 3D design technology can build on strengths and interests of students with ASD and promote social engagement in naturally occurring environments. A positive youth development philosophy focusing on technology interests may be useful with students with ASD, especially in connection to existing service delivery models.
