Behaviors exhibited by children diagnosed with Attention Deficit Hyperactivity Disorder tend to be disruptive and straining on all individuals in the classroom. As a result, several research-based best practices have been developed through previous studies in order to facilitate learning in students with ADHD. A guiding principle in these practices includes an instructional approach based on the strengths and needs of individual learners. The purpose of this study was to determine whether the specific use of constructivist practices are more appropriate/successful than traditional practices when used with elementary-aged students diagnosed with ADHD.
