In this method, each student in the group is assessed compared to the other members of the group. For example:
This person: works with the group to reach a consensus view and then abides by that consensus; works with others to finish the assignment; compromises; does their assigned tasks and does not intrude on others' tasks
Score 0 : no help at all in this respect
Score 1 : quite poor in this respect
Score 2 : not as good as most of the group
Score 3 : about average for this group
Score 4 : better than most of the group
Score 5 : really excellent for this group
The assessment may be completed by the lecturer but is normally done by self and peers. Three to six criteria are used and the marks are normalized to give a final group contribution weighting between ~0.5-1.5. For a worked example of how to normalize the marks to get a group contribution weighting, see http://www.webpaproject.com/?q=node/125 .
The product mark is then multiplied by this group contribution weighting. For example, the group gets 80% for the product.
- A student with a group contribution weighting of 1.2 gets 1.2x80% = 96% for the assignment
- A student with a group contribution weighting of 0.8 gets 0.8x80% = 64% for the assignment
The aim of a well functioning group is for every member to receive a weighting of 1.
n.b. The Statement of Assessment Methods needs to include a statement along the lines of, "The maximum mark for this assignment is 100%." Note that a student cannot get less than zero using this method.
