What strategy would most help students identify the structure of a nonfiction text they are about to read?

Previewing titles, headings, and captions is an effective strategy for helping students identify the structure of a nonfiction text. This approach allows students to quickly grasp the main topics and subtopics presented in the text, which is crucial for understanding the organization and flow of information. By examining the titles, students can infer the main ideas, while headings and subheadings break down the content into manageable sections, making it easier to anticipate the topics covered.

Additionally, captions provide context to images and diagrams, further enhancing comprehension. This initial overview sets a framework for students and enables them to navigate the text more effectively, allowing them to engage with and retain the information presented. Other strategies, while useful for different purposes, do not directly target the structural elements of the text in the same way.
