In our chosen article, written by Katie Hart, Greta Massetti, Gregory Fabiano, Meaghan Pariseau and William Pelham Jr., the topic and research discussed is classroom behaviour of children with ADHD. ADHD is a chronic health disorder, causes students with ADHD to have “difficulty paying attention, losing control of their impulses, and activity modulation”, which results in an impairment of their social and academic success. These can result in off-task behaviour in students with ADHD, as well as conflicts with students, teachers, and disruption of classroom instruction and environment.
