Robert and David Johnson, two published authors and faculty members of the College of Education at the University of Minnesota, stated that when working in groups, there are three ways in which students their team interacts with the rest of the world; they may compete to see who is “better” in the group, they may not pay attention to other students and work individually, or they may work cooperatively with the rest of the team while having an interest in the learning styles of others. Some children become dependent on the work ethic of other students, causing a decline in the student's motivation and responsibility for doing their work. When grouping multiple students to perform a shared task, more advanced students can take on most of the project for ease and speed. However, this action does not help those who have difficulty learning and can lead to students relying on others to complete their work. This result may overall decrease their effort in class. Due to inaccurate individual assessments, sometimes all members receive equal 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 being credited for your work
