Many
people consider skimming and scanning search techniques rather than reading
strategies. However when reading large volumes of information, they may be more
practical than reading. For example, you might be searching for specific
information, looking for clues, or reviewing information.
Skimming
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.
Scanning
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.
There
are different styles of reading for different situations. The technique you
choose will depend on the purpose for reading. For example, you might be
reading for enjoyment, information, or to complete a task. If you are exploring
or reviewing, you might skim a document. If you're searching for information,
you might scan for a particular word.
