Peer mediated interventions have been effective in teaching academic and social skills to students with disabilities. The present study assesses the effectiveness of students with autism spectrum disorder serving as the tutor and tutee. Four peer mediators and four students with autism spectrum disorder used technology and the simultaneous prompting procedure to teach acquisition of social studies vocabulary. Results indicate that both students with and without autism spectrum disorder effectively delivered instruction using technology and all students learned a portion of the vocabulary taught by a same-aged peer.
