Robert and David Johnson, two published authors and faculty members at the University of Minnesota's College of Education, said that when working in groups, students will interact in three ways with the rest of their team; they may compete to see who is "the best" in the group, they may pay attention to other students and work individually, or they may work cooperatively with the rest of the team while paying attention to learning styles of others. Some children become dependent on the work ethic of other students, leading to a decline in the student's motivation and responsibility to complete their own work. When you group multiple students together to complete a shared task, more advanced students can take on the majority of the project for simplicity and speed. However, this action does not help those who have difficulty learning and can lead to students relying on others to complete their own work. This result can generally reduce their efforts in class. Due to inaccurate individual assessments, all members sometimes receive the same credit despite their unequal efforts, which can cause students to fall behind due to false assessments. This act can clearly have a negative impact on students who rely on others to do their work. Advance in a class after receiving credit for work completed
