Virtual reality technology (VR) was growing strongly and applied in education in general and special education in particular. Many studies have shown the benefits of using virtual reality in the education of children with disabilities. By using experimental methods and case studies, the article presents in detail how to conduct as well as the results of 09 experimental sessions for 02 students with Attention Deficit – Hyperactivity Disorder (ADHD) in Hanoi. Experimental results show that both children showed improvement in concentration at the end of the sessions, but 09 training sessions are too short because each session lasts for only 7-20 minutes; therefore, it is not enough to conclude the progress for 02 children with ADHD. Hence, this study proposes that a longer experimental period is needed in combination with educational therapies for children with ADHD. Additionally, VRapeutic software also needs to be further improved in both quality and price adjustment in order to match with the Vietnamese context.
