Extracurricular activities are a large part of society. There are professional athletes and leagues for almost every sport possible. Sports can even provide an opportunity to earn collegiate scholarships and have some, if not all, of someone’s college education paid for. Outside the sports world, there are things such as music, art, dancing, etc. that people also participate in for enjoyment or expression. Many people start out participating in these activities during their middle-school years. Middle-school years can also bring more severe behavioral problems in children as they continue to develop more into their own people, and their personalities continue to emerge, which can have an effect on their choice participate in extracurricular activities or not. This research reviews different studies in order to answer the question of: Do middle school-aged children that participate in extracurricular activities have better classroom behavior than their peers that do not?
