Which type of arrangement is designed for a small class size and facilitates effective discussion and demonstrations?

The U-shaped arrangement is specifically designed to enhance interaction and visibility, making it particularly effective for small class sizes. This format facilitates group discussions and allows everyone to see and engage with both the instructor and each other, which is essential for demonstrations and collaborative activities. The open side of the U permits easy access for the instructor to engage directly with students, and it fosters a more intimate learning environment.

In contrast, a circular arrangement can be effective for discussions as well, but it may not provide the same level of visibility for demonstrations as the U-shaped arrangement. The theater-style arrangement is typically used for larger audiences where lectures or presentations take place without interaction, limiting discussion opportunities. The boardroom arrangement is often used in formal meetings and may not accommodate demonstrations as effectively as the U-shaped setup does. Thus, the U-shaped arrangement stands out as the optimal choice for promoting engagement and effective communication in a small class setting.
