Final answer:
A circular seating arrangement is most suitable for whole-class discussions planned by Mr. Hernandez as it facilitates visibility, participation, and equality among students.
Step-by-step explanation:
The most suitable classroom arrangement for Mr. Hernandez's new unit focused on whole-class discussions would be a circular seating arrangement. This setup allows all students to face each other and facilitates eye contact and equal participation. Unlike U-shaped seating or rows of desks facing the front, which can limit visibility for some, or small clusters of desks for group discussions, which is more suitable for small group interactions, a circular arrangement ensures that every student can be seen and heard by both the teacher and their peers.
In a whole-class discussions setting, it is essential to create an environment where students feel connected to the conversation. In a circle, there is no front or back of the room, which minimizes feelings of hierarchy among students. This classroom setup also signals to the students that their ideas and contributions are considered on equal footing. Moreover, circular setups can help in addressing classroom dynamics where some students might otherwise feel marginalized or less inclined to participate due to their placement in the room.
