The first concept of equity norm is a social standard that encourages distributing rewards and resources to members in proportion to their input. This means that a project assigned to a group, each member gets his own grade according to the work and effort he put into the project. This means that each member gets a grade rather than a group grade that the entire group gets based on the outcome and the final stage of the project. This is a problem to some students who try to slack off on their part of the project and depend on others to get a good group grade, rather than get graded for their own efforts. .
The equality norm is a social standard that encourages distributing rewards and resources equally among all members. This means that in the case of a group project, each member gets the same grade as the others. This is in contrast to the equity norm, that divides the grade or percentage according to individual efforts. The equality norm is in a sense unfair to group members who work really hard on a project and even do the assignments of the others who try to slack, and at the end get the same grade as the slackers. This is also unfair in the sense that people who only do 20% percent of the project get the same grade as people who did 80% of the project. This can be the cause of conflict between group members.
A Resource Dilemma is a situation which tempts individuals in ways that will benefit them initially, but will prove detrimental, in the long run, both to them and to the group as a whole. I don't think this dilemma forms to much between project groups at schools. I think the only resource they are all competing for is the grade, so unless the grade is distributed on equity basis then I can see how one member would try to take the highest grade, but I think if the rest work just as hard they will get the same high grade. One member getting a high grade does not mean that there are no more points left for the rest of the members.
