Here are a few things to keep in mind when doing so. Choose between a topic outline and sentence outline. With a topic outline, the headings and subpoints are all given in single words or short phrases. With a sentence outline, all of the headings and subpoints are provided in complete sentences. Topic outlines are usually used when your research deals with many different issues that can be arranged in different ways.
Sentence outlines are usually used if your research focuses on complex issues. Some instructors will insist that you must not combine these two forms. Many others, however, offer one exception to this guideline by allowing the main section headings to be short phrases while the remaining subpoints are written as full sentences.
Most outlines use an alpha-numerical structure. This structure uses a series of letters and numbers to identify and arrange section levels. In sentence outlines, headings and subpoints are almost always written with correct sentence capitalization rules.
This is not always the case with topic outlines, though. One school of thought indicates that first level headings should be written in all capital letters while all remaining headings use standard sentence capitalization rules. Another school of thought suggests that the first level headings should only have the first letter of each word capitalized, rather than the entire word.
