Which potential obstacle might affect a visually impaired student's engagement in the classroom?

Inadequate lighting can significantly hinder a visually impaired student's ability to engage in classroom activities. Proper lighting is crucial for visually impaired individuals as it can improve the contrast of materials and enhance visibility for those who may have some residual sight. Without adequate lighting, even students who use magnifying devices or Braille may find it difficult to read materials or follow visual presentations on the board or screen. This limitation can cause frustration, reduce participation levels, and ultimately impact their overall learning experience.

Other factors like peer relationships, access to technology, and curriculum difficulty may also play roles in a student's engagement, but they do not directly affect the fundamental ability to see and interact with visual materials in the classroom environment in the same immediate way that lighting does.
