A multiple baseline single subjects design across participants has been utilized. The participants of the study were 8 elementary students with ADHD diagnosis who were selected from two special education school-based settings. The results were analyzed by visual analysis of data points(level and trend)in experimental phases and the effects of these treatments techniques for students with ADHD have been discussed.
