This document discusses the importance of visualization in reading comprehension. It notes that some challenges with teaching visualization include students lacking background knowledge or vocabulary. Effective visualization involves making words and ideas into mental pictures, sounds, feelings and connections. When expert readers visualize, they place themselves in the text and become engaged with it, which improves comprehension and enjoyment. The document provides examples of visualizing a passage about a day at the beach and recommends explicitly teaching visualization by reviewing components, modeling it with a familiar text, and having students practice visualizing.
