When students work in groups there may be some discussion about individual opinions and ideas. It is almost impossible for people to work in groups to always agree. In cooperative goal structures students may have trouble agreeing on how to achieve the group's goals (Johnson, 2003, p. 11). Not everyone thinks the same way, so an obvious conflict may arise, especially when everyone must agree unanimously since it is a group effort and the outcome represents everyone. Another disadvantage I found in my research was when working in groups, some may want to socialize or relax more. Some students may do less because they know others will cover their load because they don't want to fail. This is called social loafing. Anderson suggests that one way to eliminate this problem is to “have total individual responsibility that eliminates the positive interdependence that is the basis of cooperative work” (Anderson, 2006, p. 7). Since the cooperative learning structure has so many other benefits, I don't think it's feasible
