Outlining is helpful in brainstorming, structuring and defining arguments and relationships before writing begins. When creating outlines in APA style, roman numerals define the main topics in a project. The second level, or sub-topic, should be specified with capital letters. Third level topics, subsumed in second level subject matter, are denoted with Arabic numerals, followed by lowercase
. letters for fourth-level topics. Note that not all four levels are mandatory when creating an APA outline, but each level should contain at least two headings.Most universities have resource centers to assist students in writing APA style outlines. Important stylistic concerns include making sure that each heading and subheading maintains parallel structure. Top level headings should be coordinated so that each one contains level of the highest importance, and subheadings should contain more specific, or subordinate, information.A sample APA outline would appear as follows:I. Top Level Point (General)A. Subtopic 1 (Specific)B. Subtopic 2i. Idea 1 (More specific)ii. Idea 2a. Idea 1 (Most specific)b. Idea 2II. Second Top Level Point (General and of same important as I.)III. Third Top Level Point (General and of same importance as II.)Another example of an outline written in APA format can be seen at http://owl.english.purdue.edu/owl/resource/544/03/.The APA style is a standard set of rules for scientific writing first established 80 years ago. The style is used in writing research papers for academic and research purposes. The APA, or the American Psychological Association, publishes a comprehensive, updated guide to the style called The Publication Manual of the American Psychological Association every few years. The most current version of The APA style is the 6th Edition. In general APA style emphasizes factual writing that highlights information rather than highly stylized prose. Its purpose is to standardize scientific writing across a variety of disciplines, particularly in regard to citation of sources.More reference links: http://www.apastyle.org/learn/index.aspx http://owl.english.purdue.edu/owl/resource/544/01/
