Grouping students is extremely important. This allows students to learn from one another. You can have formal or informal groups. Formal groups are teacher-driven allowing for students to be in groups that are diverse or homogeneous based on what is in involved. Group work should be rigorous, but not so rigorous that the students give up. Making sure each group member knows their role and what they are responsible for doing in the group is also important. Students can be graded as a group, individually, or self-assess.
