Assign Roles

The submissions limitation helps all group members take the work seriously and encourages your students to think carefully before they submit their responses.

Well-defined roles help your students to work productively together; preferably students should change roles during the term in order to practice the skills required for each role. Common roles for 3- and 4-person groups are described in the following table.
