Order of importance is most often used in description, narration, cause and effect, comparison contrast, or argument essays when the writer wants to emphasize the most to least important ideas or the least to most important ideas.
is it true? thanks!
The answer I would give you to this question is a qualified yes. Many writers use the most important to least important ideas while others use the opposite of least important to most important. For cause and effect, this works well, as it does for comparison/contrast or argument pieces. So that is true; however, that does not mean that these two are the only ways to organize especially if you include narration and description. Sometimes it is more effective to use chronological order. However, if your one objective is to emphasize which ideas are the most or least important, it is true that this is the way to organize. I just would caution you that you must look first at what you are writing about and what you want to achieve.
No. Order of importance is not used for all modes of writing. For example, if you are writing a narrative essay that tells a story, often using order of time is most logical. For example, if you are writing a narrative about how a person changed your life, you would probably begin chronologically and discuss when you first met that person, and work up to the climax of the story, which would be the event or events that involved you and that person; you would then mold that story into how the person changed you.
Order of importance would work best with Argument and Causal Analysis (cause/effect). Most likely you would begin with the least and work to the strongest so that your essay ends strongly. You may use compare/contrast with order of importance, but I think it would depend on the topic choice.
