What factor is crucial for a teacher to consider when selecting texts for student assessments to enhance comprehension?

A reader's cultural background knowledge is crucial for a teacher to consider when selecting texts for student assessments to enhance comprehension because it directly influences how students connect with and understand the material. Texts that resonate with a student's personal experiences, values, and community narratives engage them more effectively, thereby facilitating deeper comprehension and meaningful analysis. When students encounter content that reflects their backgrounds and realities, they are more likely to relate to, empathize with, and critically evaluate the text.

By recognizing and incorporating students' diverse cultural experiences, teachers can create a more inclusive and relevant learning environment. This not only promotes comprehension but also encourages an appreciation for different perspectives. In contrast, the other factors—like the timing of assessments, popularity, or the age of the texts—may play a role in the selection process, but they do not significantly influence a reader's ability to comprehend the material in the same foundational way that cultural background knowledge does.
