What is an abstract?
An abstract is a condensed version of a longer piece of writing that highlights the major points covered, concisely describes the content and scope of the writing, and reviews the writing's contents in abbreviated form.
How to write an informative abstract?
communicate specific information from the report, article, or paper.
include the purpose, methods, and scope of the report, article, or paper.
provide the report, article, or paper's results, conclusions, and recommendations.
length: from a paragraph to a page or two, depending upon the length of the original work being abstracted. Usually informative abstracts are 10% or less of the length of the original piece.
allow readers to decide whether they want to read the report, article, or paper.
·After you've finished rereading the article, paper, or report, write a rough draft without looking back at what you're abstracting.
Don't merely copy key sentences from the article, paper, or report: you'll put in too much or too little information.
Don't rely on the way material was phrased in the article, paper, or report: summarize information in a new way.
1. Make the abstract easy to read.
a. Use familiar words. If unfamiliar words are necessary, define them.
b. Avoid jargon.
c. Use active verbs rather than passive verbs.
d. Use short sentences, but vary sentence structure so that the abstract doesn't sound choppy.
e. Use complete sentences. Don't omit articles or other little words in an effort to save space.
f. Unless the abstract is very short (100-125 words), divide it into several paragraphs.
2. Be concise.
a. Rephrase ideas from the original document in your own words to condense the meaning into fewer words than the original used.
b. Use standard abbreviations.
c. Give information only once.
3. Be exact and unambiguous. If the article itself is unclear, use exact quotes from the article in quotation marks.
4. Use the same tone and emphasis that the original used. however, it is not necessary to follow the author's organization, wording, or even proportions. The more poorly the original article is written, the more changes you will need to make in the abstract.
5. Organize the information in the way that will be most useful to the reader. Most readers find that a thesis-first abstract is most useful, that is, start with the thesis, conclusion, or findings, then go on to the supporting data or details.
6. Do not comment on or evaluate the article. An abstract should not be confused with a review.
