Final answer:
The strategy that uses graphic representation of chapter major headings is the creation of outlines, which supports structured learning and information retention through visualization.
Step-by-step explanation:
The textbook learning strategy that results in a graphic representation of each of the major headings in a chapter is an outline. Creating chapter outlines is an effective pedagogical framework that helps students structure their learning and retain information more effectively. The process involves distilling the content into manageable sections, based on the major headings, learning objectives, key terms, and summaries provided in the chapter.
These outlines serve as a visualization of the chapter's structure, enabling students to see the relationships between different sections and the progression of ideas. It's an approach that aligns well with educational practices that activate students’ thinking about new information by chunking content into sections and objectively guiding them through learning outcomes. Moreover, embedded questions and brief activities within the chapters encourage active learning and ensure students engage with the material in a meaningful way.
