What should be visible behind the instructor in a classroom?

In a classroom setting, having a blank wall or a projection screen behind the instructor is often optimal for several reasons. This arrangement ensures that the focus remains on the instructor and the materials being presented, such as slides or videos displayed on the projection screen. A blank wall or projection screen provides a clear and unobstructed view, minimizing distractions that could divert attention from the lesson.

Moreover, a projection screen serves as a functional space for visuals that enhance the learning experience, allowing the instructor to integrate multimedia effectively. It also enables the projection of important information, diagrams, or other educational resources that support the lesson. The absence of clutter or unrelated visuals behind the instructor helps maintain a professional environment conducive to learning.

While posters, maps, real-life photographs, and other visuals can enrich a learning space, they can also potentially distract students from the focal point when situated directly behind the instructor. Therefore, a blank wall or projection screen is preferable for maintaining clarity and focus during instruction.
