The group task (production of the collective report) is not assessed and the
activity remains optional. However the group's task is linked to individual
assessment task and students are encouraged to make reference to peer
contributions in their individual assessment. By completing this task, students
can combine their efforts to cover a bigger portion of the work than they could
achieve on their own and in turn this may help their completion of the course
assignment (leading to positive interdependence and promotive interaction).
