In which arrangement does the facilitator have a low degree of control while providing high interaction opportunities?

The arrangement that allows the facilitator to have a low degree of control while providing high interaction opportunities is the half-round or crescent setup. This arrangement promotes a more open environment where participants can easily see and engage with one another, fostering communication and interaction.

The half-round design creates a more relaxed and informal atmosphere, making it easier for participants to discuss ideas, share feedback, and collaborate. Participants are facing each other, which encourages dialogue rather than just a one-way flow of information from the facilitator to the audience. This setup helps to facilitate participatory learning, where the group is empowered to take an active role in the learning process, rather than being passive recipients of information.

In contrast, the other arrangements often have a more structured setup that limits interaction. For example, an amphitheater typically has seats arranged in a way that emphasizes the speaker and minimizes participant engagement, leading to a higher degree of control by the facilitator. Similarly, a traditional classroom layout focuses on rows of desks directed toward the front, where the instructor leads the session, while a semi-circle may still not provide the same level of engagement as the half-round.
