Which classroom arrangement is best for the discussion method of instruction?

The hollow square arrangement is ideal for the discussion method of instruction because it facilitates open communication and interaction among all participants. In this setup, all learners are positioned in a way that allows them to see and engage with each other directly, promoting a sense of equality and collaboration. The configuration encourages dialogue and makes it easier for instructors to involve everyone in the discussion, creating an inclusive environment where diverse perspectives can be shared and explored.

In contrast, the large U-shaped arrangement also supports discussion but can be less effective for larger groups as the width of the U can sometimes lead to participants feeling disconnected from each other. The auditorium arrangement does not support interactive discussion effectively, as it typically involves a one-way flow of information from the instructor to the audience. Similarly, the theater arrangement is designed primarily for presentations and performances, which limits the opportunity for participants to engage in discussions or interact with one another.
