Students performing in a group have their individual assignments to turn in for their individual grade. The students who work in a cooperative learning environment will turn in a group assignment and each get the same grade for the finished product. Since tasks are usually assigned in a cooperative learning task by the members, all the students are in charge of their own job instead of group work where one student usually takes charge and does all the work. Group work is usually set up in large amounts of students and cooperative learning groups have no more than five students (Johnson & Johnson, 1991). Based on this evidence, when cooperative learning is not overused, this approach is best to use.
