Which factor can restrict interaction with a larger class?

The factor that can restrict interaction with a larger class is the learning environment arrangement. This refers to how the classroom or training space is set up, including the layout of desks, seating arrangements, and availability of resources. An arranged environment that does not foster interaction—such as rows of seats facing the front or limited space for group work—can inhibit communication and collaboration among students.

In contrast, a well-structured learning environment promotes engagement and interaction, facilitating discussions and teamwork. If the arrangement is not conducive to moving around or grouping up, it limits opportunities for students to engage actively with one another and their instructor, which can detract from the overall learning experience.

While factors like student diversity, weather conditions, and changing instructors can affect a class's dynamics, they do not directly control the layout or organization of the learning environment in the same way that the arrangement does. A well-planned environment is crucial for maximizing participation and interaction, especially in larger groups.
