Thinking About Assessment

So what if assessment becomes a way of thinking about our thinking, of documenting where we have been and making plans about where we are going.  What if we moved our thinking from a focus on the individual to the group--not group assessment like group A gets one grade and writes one paper--but group meaning--how did our being together during this time impact your thinking and how did you contribute to others in this group.  Is there a way to move assessment from a focus on the individual to a focus on the collective.  Need to think about this some more.
