It is used to quickly identify the main ideas of a text. When you read the newspaper, you're probably not reading it word-by-word, instead you're scanning the text. Skimming is done at a speed three to four times faster than normal reading. People often skim when they have lots of material to read in a limited amount of time. Use skimming when you want to see if an article may be of interest in your research.
There are many strategies that can be used when skimming. Some people read the first and last paragraphs using headings, summarizes and other organizers as they move down the page or screen. You might read the title, subtitles, subheading, and illustrations. Consider reading the first sentence of each paragraph. This technique is useful when you're seeking specific information rather than reading for comprehension. Skimming works well to find dates, names, and places. It might be used to review graphs, tables, and charts.
You quickly go through a twenty-page report in a few minutes, and determine the overall subject, tone, and a few key points. This is skimming.
You pick up the newspaper in the doctor's office, thumb through the first few pages, and gather the gist of the events happening in the world. This is skimming.
What is Scanning?
It is a technique you often use when looking up a word in the telephone book or dictionary. You search for key words or ideas. In most cases, you know what you're looking for, so you're concentrating on finding a particular answer. Scanning involves moving your eyes quickly down the page seeking specific words and phrases. Scanning is also used when you first find a resource to determine whether it will answer your questions. Once you've scanned the document, you might go back and skim it. When scanning, look for the author's use of organizers such as numbers, letters, steps, or the words, first, second, or next. Look for words that are bold faced, italics, or in a different font size, style, or color. Sometimes the author will put key ideas in the margin.
Reading off a computer screen has become a growing concern. Research shows that people have more difficulty reading off a computer screen than off paper. Although they can read and comprehend at the same rate as paper, skimming on the computer is much slower than on paper.
Example:
You flip through an accounting report to find a particular set of data. This is scanning.
You open the classified section of a newspaper, find the automobile section, and then mark a few cars within your price range. This is scanning.
