A study by Florida International University researchers found that certain changes to classroom programs for students with attention deficit hyperactivity disorder show promise, while some widely used accommodations do not appear to help. The findings were published in JAMA Pediatrics.
Behavioral interventions cut classroom rule violations by 37% compared with a general classroom setting. Stimulant medication reduced rule violations by 61% and helped students complete more assignments correctly.
Researchers recommend setting clear expectations, giving consistent feedback and praise, and rewarding children when they meet their goals.
Tools such as extra time, frequent breaks and quiet workspaces are often recommended for students with ADHD. According to the study, none of the four accommodations tested significantly improved classroom behavior or quiz scores, and some led to lower productivity.
The researchers followed about 200 children from kindergarten through sixth grade in FIU’s Summer Treatment Program. The work builds on decades of research by the late William E. Pelham Jr., founding director of FIU’s Center for Children and Families.
Dr. Gregory Fabiano, a psychology professor at FIU, said educators and caregivers should focus on social relationships, emotional regulation and academic achievement.
