What does consistently tilting the head to read letters indicate about a student?

Consistently tilting the head to read letters typically indicates that a student is utilizing an eccentric viewing pattern. This behavior often arises when an individual has a visual impairment or limited central vision, which leads them to use peripheral vision instead. By tilting their head, they are attempting to create a better line of sight to read more effectively, compensating for their vision challenges. Eccentric viewing is a strategy employed by those with macular degeneration, for example, where they find alternative ways to focus on text or objects that are difficult to see directly.

This behavior contrasts with options suggesting severe eye pain or attempting to enhance vision, as those would likely lead to different responses or strategies rather than head tilting. Similarly, head tilting would not typically be characteristic of someone practicing for a vision test. Therefore, the use of an eccentric viewing pattern is the most accurate indication in this context.
