The purpose of this study was to investigate the effectiveness of using Disc ‘O’ Sits, on improving third grade students' on-task behaviors while engaged in a language arts task. A single subject, A-B-A-B design was utilized which included three third-grade students ranging in age from 8 to 10 years. All three participants were male and had a documented history of attention difficulties within the classroom. During baseline and withdrawal phases, participants sat on their classroom chairs, while during the intervention phases, they sat on Disc ‘O’ Sit cushions. The target students were observed for in-seat behavior and engagement. Data were graphed and visually analyzed for differences between study phases. Results were varied for each student. Marked improvement in in-seat behavior was noted in one student, while another student demonstrated possible improvements in engagement. A third student did not show improvements in either in-seat behavior or engagement.
