Group Work
Graded group work is always assessed with a rubric specific to the assignment which is discussed with students in advance. Students are assessed individually on their contribution to and the quality of their individual performance; the quality of the group's overall performance (which is defined in advance in the rubric) is also assessed.
For example, in a group translation, translation mastery is assessed for the whole group (since the whole group worked together on it), but a student's comprehension and on-task behavior during the translation process are graded individually.
