Which seating arrangement permits instructor presentation and total group discussion but not small-group interaction?

The auditorium or theater seating arrangement is designed to focus attention on the instructor or presenter while allowing for total group discussion. This setup typically features rows of seats facing the front, which is optimal for lectures or presentations where the instructor delivers information to the entire audience. Since the seating is often fixed and does not allow for movement or reconfiguration, it does not support small-group interactions effectively.

In contrast, the other arrangements like circled chairs, fan or chevron, and horseshoe or U shape are designed specifically to facilitate interaction among smaller groups. These arrangements encourage engagement, dialogue, and collaboration among participants, making them less suitable for scenarios where small-group interaction is not desired. Thus, the auditorium or theater arrangement is the best choice for an environment that prioritizes instructor-led presentation with the possibility of whole group discussions while inhibiting small-group dialogue.
