Which setup is less effective for facilitating group discussions?

The theater style setup is less effective for facilitating group discussions because it primarily focuses on presentation rather than interaction. In a theater-style arrangement, attendees are seated in rows facing a speaker or a screen, which creates a one-sided flow of information. This configuration limits opportunities for participants to engage with one another, share ideas, or actively contribute to the discussion.

In contrast, setups like circle, square, or rectangle with an open center promote interaction and encourage attendees to face one another, fostering dialogue and collaboration. The Chevron or "U" shape also enhances visibility and communication among participants by allowing them to see and engage with each other directly. Individual workstations, while good for focused tasks, do not provide a conducive environment for group discussions either, as they create physical barriers to communication. Therefore, the theater style is notably the least effective arrangement for discussions within a group setting.
