This is how I want you to approach reading, to preview material before reading it. That means scrolling through the text, scanning the table of contents, major headings, any words in bold or italics, visual aids, and any information that seems relevant. Preview is one of the most valuable steps readers can take to improve reading speed and comprehension. That’s because previewing gives the mind a framework of what will be discussed. It helps the mind understand the type of information that will be presented and how it will be organized.
