Interaction with cluster seating is a little.This can be beneficial to shy students or students who wish not to talk in a larger group. Also, the smaller group allows students an opportunity to formulate beliefs, receive feedback in a relatively safe confine of a few, and practice voicing their thoughts before opening up to the whole class. In this way, interaction can first be within a smaller safe area before moving to the larger area.
Another great feature of cluster seating a class is the teacher mobility among the students to observe or assess work. The maneuverability is great for larger classes.
