Which text feature most effectively supports comprehension of expository texts and should be taught explicitly?

• A. Headings, subheadings, and graphic organizers, along with glossaries.
• B. Color of font.
• C. Page margins.
• D. Page numbers.

Answer: (A)

Expository texts are organized to present information clearly, so teaching students to use features that reveal structure and meaning is key. Headings and subheadings signal what each section is about and how ideas are organized, which helps readers preview content, locate details, and understand relationships between ideas. Graphic organizers provide a visual way to map out main ideas, supporting details, and how concepts connect, making complex information easier to grasp and remember. Glossaries help students build and recall the specialized vocabulary often found in informational texts, so terms don’t block comprehension.

Color of font, page margins, and page numbers don’t actively support understanding the content in the same way. They may affect readability or navigation but don’t guide students in identifying main ideas, organizing information, or clarifying vocabulary. Because the combination of headings, subheadings, graphic organizers, and glossaries directly enhances students’ ability to locate, connect, and understand information, it’s the most effective set to teach explicitly.
